Description

  The present invention relates to an earthquake information distribution system that distributes earthquake early warnings to mobile communication terminals, and a mobile communication terminal and an earthquake information distribution apparatus used in this system.

  In recent years, with the advancement of earthquake engineering technology, the rapid development of information communication technology and computer technology is remarkable. By using these technologies comprehensively, the earthquake early warning technology that catches the occurrence of seismic waves at an early stage and transmits the earthquake early warning to the user terminal before the main motion of the earthquake arrives is being put into practical use. In.

  Seismic waves are broadly divided into P waves (primary waves; longitudinal waves) that propagate relatively fast, and S waves (secondary waves; transverse waves) that propagate late and cause major destruction phenomena. The fine movement, the vibration caused by the latter, is called the main movement. Earthquake destruction is mainly caused by the latter main motion.

  The Earthquake Early Warning Technology estimates the magnitude and location of earthquakes by observing P-waves and analyzing their characteristics, and uses the earthquake information related to the estimated magnitude and location of earthquakes to cause major earthquake motions. It is intended to minimize physical and human damage caused by the main motion of the earthquake by transmitting to the various areas in real time when the wave arrives. For example, when it is assumed that a Tokai earthquake has occurred, it is possible to transmit an emergency earthquake bulletin to Tokyo approximately 50 seconds before the main motion reaches Tokyo.

  Such earthquake early warning technology has been developed in Japan mainly by the National Institute for Disaster Prevention Science and Technology (hereinafter referred to as the National Research Institute for Disaster Prevention) and the Japan Meteorological Agency. We have a large scale seismic network. The real-time earthquake information provided by the National Institute for Disaster Prevention is called “real-time earthquake information” until January 2004, and is generated based on the signals generated from the earthquake observation network by the high-sensitivity seismometer, etc. possessed by the National Institute for Disaster Prevention. Is done. On the other hand, the real-time earthquake information provided by the Japan Meteorological Agency is called “Nowcast Earthquake Information” until January 2004, and is based on signals generated from the earthquake observation network by multi-function seismometers etc. possessed by the Japan Meteorological Agency. Generated. The “Real-time Earthquake Information” of the National Institute for Disaster Prevention and the “Nowcast Earthquake Information” of the Japan Meteorological Agency have been unified into the term “Emergency Earthquake Information” since February 2004.

On the other hand, in order to minimize disasters caused by earthquakes, it is not enough to improve the accuracy of earthquake information and increase the speed of earthquake detection. In addition, research, development and dissemination of a system that delivers accurately is essential. For example, a system for distributing emergency earthquake information to a mobile communication terminal registered as a user by using a mobile communication terminal such as a car phone or a mobile phone, which has recently been popular, has been proposed (for example, see Patent Document 1). ).
JP 2001-307265 A

  However, in spite of the fact that real-time performance is required for earthquake early warning, the conventionally proposed earthquake information distribution system has poor real-time performance, and emergency earthquake information often reaches the user terminal after the arrival of the main motion of the seismic wave. Further, the distributed emergency earthquake information generally includes only basic information elements such as an earthquake occurrence time, an epicenter location, and a magnitude. For this reason, the emergency earthquake information distributed in the user terminal is not fully utilized.

  The present invention has been made paying attention to the above circumstances, and its purpose is to improve the real-time property of earthquake early warning and provide an earthquake information distribution system capable of providing highly effective earthquake information for the user and its It is to provide a mobile communication terminal and an earthquake information distribution apparatus.

In order to achieve the above object, the first invention is connected via a communication network to an earthquake observation network that transmits emergency earthquake information including information indicating an earthquake occurrence time, an epicenter location, and an earthquake scale when an earthquake occurs. And an earthquake information distribution system comprising a mobile communication terminal capable of communicating with the earthquake information distribution apparatus via a mobile communication network,
Means for receiving emergency earthquake information transmitted from the earthquake observation network to the earthquake information distribution device, and converting the received emergency earthquake information into a format that can be transmitted by a short message, and converting the converted emergency earthquake bulletin Means for inserting into a short message and transmitting to the mobile communication terminal.

  The mobile communication terminal also includes means for receiving a short message transmitted from the earthquake information distribution apparatus and emergency earthquake information inserted in the received short message as a first report to the user of the mobile communication terminal. Based on the means for notifying, the means for detecting the current position of the mobile communication terminal, and the detected current position and the emergency earthquake information inserted in the short message, the main motion of the earthquake is detected by the mobile communication terminal. Means for predicting the time to reach the current position or a margin time until the current position and means for notifying the user of the predicted arrival time or the margin time for arrival as the second report are provided. .

  Therefore, according to the first invention, when emergency earthquake information is generated from the earthquake observation network, first, this emergency earthquake information is sent from the earthquake information distribution device to the short message service (Short Message Service; SMS) is distributed to the mobile communication terminal and notified to the user as the first report. For this reason, for example, when transmitting emergency earthquake information after a communication link is established between the earthquake information distribution device and the mobile communication terminal, or when distributing emergency earthquake information using e-mail via the Internet In comparison, it is possible to distribute emergency earthquake information with less delay time.

  In addition, after the notification of the first report, in the mobile communication terminal, there is a margin until the main motion of the earthquake reaches the current position of the mobile communication terminal based on the current position of the own terminal and the received emergency earthquake information. Time is predicted, and the predicted allowance time is notified to the user as the second report. For this reason, the user can know the allowance time until the main movement reaches the position where the user is present from the second report, so that the immediately preceding avoidance action such as fire extinguishing or evacuation under the desk as necessary. It becomes possible to take.

  That is, in the first invention, the emergency earthquake information is first notified as the first report, the prediction calculation of the arrival time of the main motion is performed after the start of the notification of the first report, and the result is notified as the second report. The For this reason, for example, after the calculation of the surplus arrival time is completed, the emergency earthquake information notification delay is minimized, and real-time characteristics are maintained, as compared with the case where the emergency earthquake information and the arrival surplus time are reported together. Is possible.

  In the first invention, the prediction calculation of the arrival allowance time is performed in the mobile communication terminal. For this reason, the earthquake information distribution apparatus only needs to transmit emergency earthquake information as the first report by a short message. In other words, there is an advantage that the present invention can be implemented with the function of the existing mail server without newly providing a special processing function in the earthquake information distribution apparatus.

On the other hand, in order to achieve the above object, the second invention provides, via a communication network, an earthquake observation network that transmits emergency earthquake information including information indicating an earthquake occurrence time, an epicenter location, and an earthquake magnitude when an earthquake occurs. In an earthquake information distribution system comprising a connected earthquake information distribution device and a mobile communication terminal capable of communicating with the earthquake information distribution device via a mobile communication network,
Means for receiving emergency earthquake information transmitted from the earthquake observation network to the earthquake information distribution device, and converting the received emergency earthquake information into a format that can be transmitted by a short message and converting the converted emergency earthquake early warning Is inserted into a short message and transmitted to the mobile communication terminal, means for acquiring information representing the current position of the mobile communication terminal from the mobile communication network, the acquired current position of the mobile communication terminal and the reception Means for predicting the time when the main motion of the earthquake reaches the current position of the mobile communication terminal or the surplus time until it arrives based on the emergency earthquake information, and the predicted arrival time or surplus time Means for inserting into an e-mail and transmitting to the mobile communication terminal.

  In addition, the mobile communication terminal includes a means for receiving a short message transmitted from the earthquake information distribution apparatus and a user of the mobile communication terminal as emergency earthquake information inserted in the received short message as a first report. Means for informing the user, means for receiving the e-mail transmitted from the earthquake information distribution apparatus, and means for informing the user of the arrival time or the arrival allowance time inserted in the received e-mail as a second report It is intended to provide.

  Therefore, according to the second invention, similar to the first invention, when emergency earthquake information is generated from the seismic observation network, the emergency earthquake information is first transmitted by a short message, which is used as the first report by the user. To be notified. For this reason, in order to distribute emergency earthquake information, mobile communication of emergency earthquake information with less delay time than when establishing a communication link between the earthquake information distribution device and the mobile communication terminal or using e-mail It can be distributed to terminals.

  In addition, after the short message is transmitted, the earthquake information distribution apparatus predicts a surplus time until the main motion of the earthquake reaches the mobile communication terminal of the distribution destination, and this surplus time is distributed to the mobile communication terminal by e-mail. This is notified to the user as the second report. For this reason, the user can know the allowance time until the main movement reaches the position where the user is present from the second report, so that the immediately preceding avoidance action such as fire extinguishing or evacuation under the desk as necessary. It becomes possible to take.

  That is, according to the second invention, emergency earthquake information is first delivered by a short message in response to the arrival of emergency earthquake information, and after this delivery, a prediction calculation of the arrival time of main motion is performed, and the calculation result is sent to an e-mail. It is delivered by. For this reason, compared with the case where the emergency earthquake information and the calculation result of the arrival allowance time are delivered together, for example, it is possible to minimize the notification delay of the emergency earthquake information, thereby ensuring the real time property.

  Moreover, the prediction calculation of the arrival allowance time is performed by the earthquake information distribution apparatus. For this reason, the mobile communication terminal only needs to have a short message and electronic mail receiving function distributed from the earthquake information distribution apparatus. In other words, there is an advantage that the present invention can be implemented with the existing configuration without newly providing a special processing function in the mobile communication terminal.

The first and second inventions are characterized by having the following various configurations.
In the first configuration, when an external display device can be connected to the mobile communication terminal via the short-range wireless interface, the mobile communication terminal transmits at least the first report out of the first report and the second report. The information is transferred to the external display device via the short-range wireless interface and displayed. Thus, for example, assuming a wristwatch as an external display device, the user receives and confirms the first report even when the mobile communication terminal is accommodated in a bag or the mobile communication terminal is set in a charger. It becomes possible to do.

  In the second configuration, the convergence time of the main motion of the earthquake or the convergence time required for the main motion to converge is predicted based on the emergency earthquake information, and the predicted convergence time or convergence time is described above. The user is notified as the third report following the second report that notifies the arrival allowance time. In this way, the user can know the time until the main motion converges after the main motion arrives, thereby reducing the user's anxiety.

  The third configuration predicts the seismic intensity scale at the current position of the mobile communication terminal based on the current position of the mobile communication terminal and the emergency earthquake information, and the predicted seismic intensity scale is the second and third reports. It is included in at least one of these to notify the user. In this way, the user can grasp the magnitude of the earthquake from the seismic intensity scale.

  A fourth configuration is provided with a memory for storing the seismic intensity level and a plurality of types of symbol figures representing the seismic intensity level in a shape when the seismic intensity level is notified, and a shape corresponding to the predicted seismic intensity level. The symbol figure is selected from the memory, and the selected symbol figure is blinked or lit. If it does in this way, a seismic intensity scale will be displayed using the symbol figure from which a shape differs, and, thereby, a user can grasp a seismic intensity scale easily and correctly at a glance.

  In the fifth configuration, when the seismic intensity level is predicted, when the user exists in the building, the existing level of the user in the building is detected, and the seismic level is predicted according to the detected existing level. The value is corrected. In general, seismic intensity levels of buildings are different depending on the level. Therefore, as described above, the seismic intensity scale can be predicted more accurately by detecting the level where the user exists and correcting the predicted value of the seismic intensity scale.

  In short, in the first and second inventions described above, when emergency earthquake information is generated from the seismic observation network, the emergency earthquake information is first distributed from the earthquake information distribution device to the mobile communication terminal by a short message, which is the first report. To the user. Then, in the mobile communication terminal or the earthquake information distribution apparatus, a margin time until the main motion of the earthquake reaches the current position of the mobile communication terminal is predicted based on the current position of the mobile communication terminal and the emergency earthquake information. The predicted arrival margin time is notified to the user as the second report.

  Therefore, according to these inventions, it is possible to provide an earthquake information distribution system, a mobile communication terminal, and an earthquake information distribution apparatus capable of improving earthquake real-time performance and providing earthquake information that is highly effective for the user. Can do.

Hereinafter, some embodiments according to the present invention will be described with reference to the drawings.
(First embodiment)
In the first embodiment of the present invention, when emergency earthquake information is transmitted from the earthquake observation network in the earthquake information distribution server, the format of the emergency earthquake information is converted and transmitted to the mobile communication terminal by a short message. On the other hand, when the mobile communication terminal receives the short message transmitted from the earthquake information distribution server, it first notifies the user of the mobile communication terminal of the emergency earthquake information inserted in the received short message as the first report. Next, the current position of the mobile communication terminal is detected, and the seismic intensity scale at the current position is predicted based on the detected current position and the emergency earthquake information inserted in the short message. At the same time, it predicts the surplus time until the main motion of the earthquake reaches the current position of the mobile communication terminal and the convergence time until the main motion converges, respectively. The time is sequentially notified to the user as the second report and the third report.

  FIG. 1 is a schematic configuration diagram showing a first embodiment of an earthquake information distribution system according to the present invention. This system includes an earthquake information distribution server SSV1 connected to an earthquake observation network via a communication network NW, a plurality of mobile communication terminals MS1 to MSk each possessed by a user, and wristwatches WT1 and WT2 that are always worn by the user. And.

  The earthquake observation network is composed of a plurality of seismometers D1 to Dn distributed in an observation area and an earthquake monitoring server DSV. Each of the seismometers D1 to Dn transmits a detection signal to the earthquake monitoring server DSV when it detects a seismic wave. The earthquake monitoring server DSV generates emergency earthquake information based on the detection signals transmitted from the seismometers D1 to Dn, and transmits the generated emergency earthquake information to the earthquake information distribution server SSV1 via the communication network NW. To do. The emergency earthquake information includes information indicating an earthquake occurrence time, an epicenter location, and an earthquake scale. The location of the epicenter is represented by latitude, longitude, and depth, and the magnitude of the earthquake is represented by earthquake magnitude.

  The communication network NW includes a wired communication network and a mobile communication network. In addition to public line networks such as PSTN (Public Switched Telephone Network) and ISDN (Integrated Services Digital Network), wired communication networks include computer networks such as the Internet, telecommunications carriers' dedicated lines and LANs (Local Area Networks). included.

  For mobile communication networks, mobile phone networks such as PDC (Personal Digital Cellular) network and IMT2000 (International Mobile Telecommunication 2000) network, PHS (Personal Handyphone System) (registered trademark) network, wireless LAN, commercial wireless system MCA (Multi Channel Access) system etc. are included. The communication network NW also includes an IP (Internet Protocol) network.

  The mobile communication network includes a mobile communication control station that supervises the entire mobile communication network and a plurality of base stations BS1 to BSm that are distributed in the service area. The mobile communication terminals MS1 to MSk are connected to any one of the base stations BS1 to BSm via a wireless line, and further from the base station to the earthquake information distribution server SSV1 via a mobile communication control station and a wired communication network. Connected.

  Between the mobile communication terminals MS1 to MSk and the wristwatches WT1 and WT2, a wireless interface adopting a short-range wireless data communication standard such as BT (Bluetooth) (registered trademark) or UWB (Ultra Wide Band) between the same users. Connected through.

  By the way, the earthquake information distribution server SSV1 is configured as follows. FIG. 2 is a block diagram showing the functional configuration. That is, the earthquake information distribution server SSV1 includes a central processing unit (CPU) 11. A program memory 13 and a data memory 14 are connected to the CPU 11 via a bus 12, and a communication interface 15 is further connected thereto.

  A communication interface (communication I / F) 15 performs communication between the earthquake monitoring server DSV and the mobile communication terminals MS1 to MSk according to a communication protocol defined by the communication network NW under the control of the CPU 11. For example, TCP / IP (Transmission Control Protocol / Internet Protocol) is used as the communication protocol.

  The data memory 14 is provided with a user information database 14a and an earthquake information storage database 14b. The earthquake information accumulation database 14b stores the reception history of emergency earthquake information sent from the earthquake monitoring server DSV and the distribution history of the emergency earthquake information to the user.

  The user information database 14a stores management information of users who wish to use the earthquake information distribution service. For example, as shown in FIG. 3, this user management information includes user identification information (user ID), a user's mobile phone number / short message address, presence / absence of distribution application, and position information and area indicating the user's current position. Information. The user position information is represented by, for example, latitude and longitude, and is periodically acquired and updated from the mobile communication terminals MS1 to MSk. As the area information, an earthquake early warning distribution service area is divided into a plurality of areas, and an area number including a position where the user exists is stored. The size of one area is set to a size that is estimated to be affected by almost the same effect, for example, based on the propagation speed of seismic waves.

  Further, the user information database 14a also stores calculation results of the predicted seismic intensity scale, the shaking start time, and the shaking stop time. The predicted seismic intensity level, the shaking start time, and the shaking stop time are calculated for the area where the distribution target user exists after the distribution of the emergency earthquake information. This calculation is performed by an earthquake detailed information calculation program (not shown) stored in the program memory 13.

  The program memory 13 stores an earthquake information reception control program 13a and an earthquake information distribution control program 13b as application programs for realizing the control function according to the present invention. The earthquake information reception control program 13a monitors the arrival of emergency earthquake information from the earthquake monitoring server DSV in real time, and stores the emergency earthquake information received by the communication interface 15 in the earthquake information storage database 14b.

  When the earthquake information distribution control program 13b receives the emergency earthquake information, the earthquake information distribution control program 13b sets a distribution target area based on the earthquake occurrence position and the earthquake magnitude included in the emergency earthquake information, and sets the distribution target area in the set distribution target area. An existing user is selected from the user information database 14a. At the same time, the received emergency earthquake information is converted into a format corresponding to the short message, and a short message in which the format-converted emergency earthquake information is inserted is generated. Then, this short message is transmitted to the mobile communication terminal of the selected user.

On the other hand, the mobile communication terminals MS1 to MSk are configured as follows. FIG. 4 is a block diagram showing the functional configuration.
In the figure, a radio signal transmitted from a base station (not shown) is received by an antenna 21 and then input to a receiving circuit (RX) 23 via an antenna duplexer (DUP) 22. The receiving circuit 23 mixes the received radio signal with the local oscillation signal output from the frequency synthesizer (SYN) 24 and converts the frequency into an intermediate frequency signal (down-conversion). Then, the down-converted intermediate frequency signal is orthogonally demodulated and a received baseband signal is output. The frequency of the local oscillation signal generated from the frequency synthesizer 24 is indicated by a control signal SYC output from the control unit 32.

  The received baseband signal is input to the CDMA signal processing unit 26. The CDMA signal processing unit 26 includes a RAKE receiver. In the RAKE receiver, the plurality of paths included in the received baseband signal are each subjected to despreading processing using spreading codes. Then, the signals of the respective paths subjected to the despreading process are synthesized after their phases are adjusted. Thus, received packet data in a predetermined transmission format is obtained. The received packet data is input to a compression / decompression processor (hereinafter referred to as a compander) 27.

  The compander 27 separates the received packet data output from the CDMA signal processing unit 26 for each medium by the demultiplexing unit. Then, the data for each separated medium is decrypted. For example, if audio data is included in the received packet data, the audio data is decoded by a speech codec. If the received packet data includes video data, the video data is decoded by a video codec.

  The digital audio signal obtained by the decoding process is supplied to a PCM code processing unit (hereinafter referred to as a PCM codec) 28. The PCM codec 28 performs PCM decoding on the digital audio signal output from the compander 27 and outputs an analog audio signal. The analog audio signal is amplified by the reception amplifier 29 and then output from the speaker 30.

  The digital video signal decoded by the video codec of the compander 27 is input to the control unit 32. The control unit 32 displays the digital video signal output from the compander 27 on the display 35 via the video RAM. The display 35 is configured by an LCD (Liquid Crystal Devise). The control unit 32 displays not only the received video data but also video data captured by a camera (not shown) on the display 35 via the video RAM.

  The compander 27 outputs the short message and the e-mail to the control unit 32 when the received packet data is a short message and an e-mail. The control unit 32 stores the short message and electronic mail in the storage unit 36. Then, the short message and the e-mail are read from the storage unit 36 and displayed on the display 35 in accordance with the display operation performed by the user in the input unit 34. The display 35 also displays information indicating the operation mode of the apparatus, incoming call notification information, information indicating the remaining battery level or charge state, a clock indicating the current time, and the like.

  On the other hand, the voice signal of the speaker input to the microphone 31 is amplified to an appropriate level by the transmission amplifier 33 and then subjected to PCM encoding processing by the PCM codec 28 to be converted into a digital audio signal to the compander 27. Entered. A video signal output from a camera (not shown) is digitized by the control unit 32 and input to the compander 27. Note that an e-mail created by the control unit 32 is also input from the control unit 32 to the compander 27.

  The compander 27 detects the energy amount of the input voice from the digital audio signal output from the PCM codec 28, and determines the transmission data rate based on the detection result. Then, the digital audio signal is encoded into a signal having a format corresponding to the transmission data rate, thereby generating audio data. The digital video signal output from the control unit 32 is encoded to generate video data. Then, these audio data and video data are multiplexed by a demultiplexing unit according to a predetermined transmission format to generate transmission packet data, and this transmission packet data is output to the CDMA signal processing unit 26. Note that even when an electronic mail is output from the control unit 32, the electronic mail is converted into packet data.

  The CDMA signal processing unit 26 performs spread spectrum processing on the transmission packet data output from the compander 27 using a spreading code assigned to the transmission channel. Then, the output signal is output to the transmission circuit (TX) 25. The transmission circuit 25 modulates the spread spectrum signal using a digital modulation method such as a QPSK (Quadrature Phase Shift Keying) method. Then, the transmission signal generated by this modulation is combined with a local oscillation signal generated from the frequency synthesizer 24 and frequency-converted into a radio signal. Then, the radio signal is amplified at a high frequency so that the transmission power level instructed by the control unit 32 is obtained. The amplified radio signal is supplied to the antenna 21 via the antenna duplexer 22 and transmitted from the antenna 21 to the base station.

  The input unit 34 is provided with a dial key and a plurality of function keys. The function keys include a transmission key, an end key, a power key, a volume adjustment key, a mode designation key, and a cursor key. A power supply circuit 38 generates a predetermined operating power supply voltage Vcc based on the output of the battery 37 and supplies it to each circuit unit. The battery 37 is charged by a charging circuit (not shown).

  Further, the mobile communication terminals MS1 to MSk are provided with a GPS receiver 39. The GPS receiver 39 receives GPS signals transmitted from a plurality of GPS satellites according to instructions from the control unit 32. The received GPS signals are supplied to the control unit 32 for the position calculation process of the terminal itself.

  Further, the mobile communication terminals MS1 to MSk are provided with a Bluetooth (BT) (registered trademark) interface circuit (BT I / F) 40. The BT I / F 40 transmits and receives wireless data to and from the wristwatch (for example, WT1) of the same user under the control of the control unit 32.

  By the way, the control part 32 is provided with a microcomputer, for example. As control functions according to the present invention, an earthquake information reception control function 32a, a position information detection control function 32b, an earthquake shaking time calculation function 32c, an earthquake early warning display control function 32d, and an earthquake early warning transfer control function 32e are provided. I have.

The earthquake information reception control function 32a receives a short message transmitted from the earthquake information distribution server SSV1, and extracts emergency earthquake information from the received short message.
The position information detection control function 32b periodically calculates the current position (latitude and longitude) of the mobile communication terminal based on the GPS signal received by the GPS receiver 39.

  The earthquake shaking time calculation function 32c predicts and calculates the seismic intensity scale at the current position of the mobile communication terminal based on the detected current position of the mobile communication terminal and the emergency earthquake information extracted from the short message. To do. Further, based on the detected current position of the mobile communication terminal and the emergency earthquake information extracted from the short message, an estimated time until the main motion of the earthquake reaches the current position of the mobile communication terminal is predicted. calculate. Further, based on the emergency earthquake information, a convergence time required for the main motion to converge is predicted and calculated.

  When the earthquake early warning display control function 32d receives emergency earthquake information by the short message, the earthquake early warning display control function 32d displays the received emergency earthquake information as the first report on the display unit 35. Following this first report, the seismic intensity scale and the arrival time of the main motion predicted and calculated by the earthquake shaking time calculation function 32c are displayed on the display unit 35 as the second report. Further, after the arrival margin time has elapsed, that is, after the main motion has arrived, the predicted earthquake convergence time is displayed on the display unit 35 together with the seismic intensity scale instead of the arrival margin time.

  The earthquake early warning transfer control function 32e generates a notification message for a wristwatch when emergency earthquake information is received by the short message. Then, the generated notification message is transmitted from the BT I / F 40 to the wristwatch WT1. As a notification message for a wristwatch, for example, a control message that causes an icon to blink on the wristwatch or generate vibration is used.

Next, the earthquake information distribution operation by the system configured as described above will be described. FIG. 5 is a sequence diagram used for the description.
First, when using the earthquake information distribution service provided by the system, the user accesses the earthquake information distribution server SSV1 from his / her mobile communication terminals MS1 to MSk and performs input processing for use registration. In this input process, a short message address is input in addition to attribute information such as the user's name.

  When receiving the predetermined input, the earthquake information distribution server SSV1 issues a user ID, and stores the input short message address and attribute information in the user information database 14a in association with the user ID. In the course of this registration process, the earthquake information distribution server SSV1 sends a position acquisition request to the mobile communication terminals MS1 to MSk that are registration request sources. Upon receiving this position acquisition request, the mobile communication terminals MS1 to MSk calculate the current position (latitude and longitude) of the terminal based on the GPS signal received by the GPS receiver 39, and the calculated current position (latitude Longitude) is returned to the earthquake information distribution server SSV1.

  The earthquake information distribution server SSV1 stores the current position (latitude and longitude) returned from the mobile communication terminals MS1 to MSk in the user information database 14a in association with the user ID. At the same time, an area including the stored current position (latitude and longitude) is selected from the area map stored in advance, and the number of the selected area is stored in the user information database 14a in association with the user ID. .

  Thus, the user registration process is performed. The current location of the user registered for use is periodically transmitted from the earthquake information distribution server SSV1 to the mobile communication terminals MS1 to MSk, and the mobile communication terminals MS1 to MSk respond to the acquisition request. It is updated by returning the latest current position.

  Now, assume that an earthquake occurred in the seismic monitoring area in this state. If it does so, an earthquake detection signal will be transmitted from each seismometer D1-Dn installed in the said earthquake monitoring area, and these earthquake detection signals will be collected by the earthquake monitoring server DSV. As shown in FIG. 5, the earthquake monitoring server DSV calculates an earthquake occurrence time, an earthquake occurrence position (latitude, longitude, depth), and an earthquake magnitude based on the collected multiple earthquake detection signals in step 5a. The calculated value is included in the emergency earthquake information and transmitted to the earthquake information distribution server SSV1.

  The earthquake information distribution server SSV1 constantly monitors the arrival of emergency earthquake information from the earthquake monitoring server DSV. When emergency earthquake information arrives in this state, in step 5b, a distribution target area is set based on the earthquake occurrence position and the earthquake magnitude included in the emergency earthquake information, and users existing in the set distribution target area are selected. Select from user information database 14a. This distribution target user is selected in units of areas based on the area information stored in the user information database 14a. For this reason, it becomes possible to select the user to be distributed in a very short time compared to the case of selecting based on the latitude and longitude.

  At the same time, the earthquake information distribution server SSV1 converts the received emergency earthquake information into a format corresponding to the short message. For example, if the data amount of the information element included in the emergency earthquake information exceeds the amount of data that can be transmitted by the short message, the information element data included in the emergency earthquake information is rounded up, rounded down, or rounded off. Reduce the amount. If the fonts are different, font conversion is also performed.

  Then, a short message in which the converted emergency earthquake information is inserted is created, and this short message is transmitted to the mobile communication terminal (for example, MS1) of the selected user. The short message is a simple mail transmitted using a protocol and a network unique to the carrier, and the time required from the creation instruction to transmission is short, and the transmission time is also short. For this reason, it is possible to deliver in a short time with a small delay time as compared with the case of using an electronic mail transmitted via the Internet.

  When a short message arrives from the earthquake information distribution server SSV1, the mobile communication terminal MS1 first generates a sound or vibration in step 5c as shown in FIG. 5, and also receives the emergency earthquake information of the received short message. It is displayed on the display unit 35 as one report. At the same time, in step 5d, an emergency notification message that the short message of the emergency earthquake information has been received is generated, and this message is transmitted from the BT I / F 40 to the wristwatch WT1 of the same user. When the wristwatch WT1 receives the emergency notification message, the wristwatch WT1 generates a sound or vibration and further blinks an emergency message reception icon. Therefore, even if the user does not have the mobile communication terminal MS1, it is possible to recognize the arrival of emergency earthquake information.

  Note that the sound or vibration generated in the mobile communication terminal MS1 and the wristwatch WT1 may be set to be different from that used when a normal short message and electronic mail are received. Whether the received mail is a short message including emergency earthquake information, a normal short message, or an electronic mail can be determined based on, for example, a transmission source address.

  When the notification of the first report is finished, the mobile communication terminal MS1 subsequently detects the current position of the terminal itself at step 5e. The detection of the current position may be calculated based on the GPS signal received at this time, but the closest current position detected in the past stored in the storage unit 36 may be used. As a result, the time required to detect the current position can be shortened.

  Next, the mobile communication terminal MS1 calculates a seismic intensity scale at the current position of the mobile communication terminal MS1 based on the detected current position of the mobile communication terminal and the emergency earthquake information extracted from the short message. To predict. The predicted seismic intensity scale is based on the seismic magnitude indicating the intensity of the earthquake, by considering the distance attenuation according to the distance R between the epicenter position included in the emergency earthquake information and the current position of the mobile communication terminal MS1. It can be calculated.

  At the same time, in step 5f, the mobile communication terminal MS1 determines the main motion (S wave) of the earthquake based on the detected current position of the mobile communication terminal and the emergency earthquake information extracted from the short message. A margin time until reaching the current position of the mobile communication terminal MS1 is predicted by calculation.

That is, the propagation velocity Vs of the main motion (S wave) of the earthquake is known and is about 3.5 km / sec. On the other hand, the distance R from the epicenter to the mobile communication terminal MS1 can be calculated from the current position of the mobile communication terminal MS1 and the epicenter position as described above. Therefore, from these values, the propagation time Ts of the main motion (S wave) from the epicenter to the mobile communication terminal MS1 is
Ts = Vs / R
Can be calculated as If the propagation time Ts of the main motion (S wave) can be calculated, the main motion (S wave) arrives using the earthquake occurrence time t0 and the current time t included in the received emergency earthquake information. The margin time T until
T = (t0 + Ts) -t
Can be calculated. It should be noted that the absolute time (t0 + Ts) when the main motion (S wave) reaches the current position of the mobile communication terminal MS1 instead of the margin time T until the main motion (S wave) reaches the current position of the mobile communication terminal MS1. ) May be calculated.

  When the predicted seismic intensity level and margin time are calculated, the mobile communication terminal MS1 subsequently generates earthquake detail information including the calculated seismic intensity level and margin time in step 5g, and the generated earthquake details. Information is displayed on the display unit 35 as the second report. FIG. 6A shows a display example thereof. As shown in the figure, the detailed earthquake information includes a symbol display unit 41 that represents a predicted seismic intensity scale in a symbol graphic having a different shape, a numerical display unit 42 that displays a predicted seismic intensity scale numerically, a margin time display unit 43, a caution And an item display unit 44. The symbol display unit 41 is a panic situation and allows the predicted seismic intensity scale to be easily and accurately confirmed visually at a glance. The symbol display unit 41 is a symbol combining a circular symbol and a triangle and a quadrangle. And symbols combining pentagons and hexagons. Among these symbols, the circular symbol is lit in blue when the predicted seismic intensity scale is less than 3. The triangular and square symbols are lit or blinking yellow when the predicted seismic intensity scale values are seismic intensities 3 and 4, respectively. The pentagonal and hexagonal symbols are lit or flashing red when the predicted seismic intensity scale values are seismic intensities 5 and 6, respectively. Note that “lighting” may be performed when the predicted seismic intensity level is weak, and “flashing” when the predicted seismic intensity level is strong.

  The allowance time is displayed by a message, for example, “after the arrival of the main motion“ ”seconds”. This extra time is displayed as a countdown at 1 second intervals. In addition, as notes, the content which a user should act in a short period immediately before main movement (S wave) arrival is displayed. For example, as shown in FIG. 6A, “fire extinguishment of fire” and “evacuation under the desk” are displayed.

In addition, the mobile communication terminal MS1 displays the convergence time (swing) required for the main motion (S wave) to converge based on the earthquake occurrence time and the earthquake magnitude included in the emergency earthquake information during the display of the second report. Stop time) Te is predicted by calculation. For the prediction of the shaking stop time Te, a relational expression between the magnitude of an earthquake that has occurred in the past and the duration of the earthquake is used. For example, the relationship between the magnitude of the earthquake and the duration of the earthquake draws a curve as shown by a solid line A in FIG. This relational expression is known as a relational expression of R. Dobly et al. Therefore, by calculating based on the earthquake magnitude notified by the emergency earthquake information and the above relational expression, it is possible to calculate the predicted value Te of the earthquake duration (swaying time).
Note that the prediction method using the relational expression such as R. Dobly is an example, and other known prediction methods can be applied.

  When the margin time T in the second report becomes zero, the mobile communication terminal MS1 displays the shaking stop time Te as the third report in place of the margin time T. FIG. 6B shows a display example thereof. The convergence time Te is displayed as, for example, “after the shake convergence,“ ”seconds”. The convergence time Te is also displayed in a countdown manner at intervals of 1 second, as with the margin time T.

  In FIG. 6B, the same content as that in the second report is continuously displayed as a precaution. However, different contents may be displayed. As precautions displayed in the third report, for example, check items after the shaking has converged, a wide area evacuation site in the vicinity, and the like can be considered.

  Further, the mobile communication terminal MS1 generates a drive signal for generating a different vibration pattern according to the calculated predicted seismic intensity scale and transmits it to the wristwatch WT1, whereby the wristwatch WT1 changes the predicted seismic intensity scale to a different vibration pattern. You may make it alert | report by. Further, instead of changing the vibration pattern, a light emission pattern or a sound generation pattern, or a different melody may be generated.

  As described above, in the first embodiment, when emergency earthquake information is transmitted from the earthquake monitoring server DSV, the mobile information registered by the short message after the earthquake information distribution server SSV1 converts the format of the emergency earthquake information. Transmit to terminals MS1 to MSk. On the other hand, when the mobile communication terminals MS1 to MSk receive the short message transmitted from the earthquake information distribution server SSV1, first, the mobile communication terminals MS1 to MS1 use the emergency earthquake information inserted in the received short message as the first report. Inform MSk users. Next, the current positions of the mobile communication terminals MS1 to MSk are detected, and the seismic intensity scale at the current position is predicted based on the detected current position and the emergency earthquake information inserted in the short message. At the same time, the estimated time for the main motion of the earthquake to reach the current position and the convergence time for the main motion to converge are predicted, respectively. And as a 3rd report, it notifies to a user one by one.

  Therefore, when emergency earthquake information is generated from the earthquake monitoring server DSV, this emergency earthquake information is distributed from the earthquake information distribution server SSV1 to the mobile communication terminals MS1 to MSk by a short message, and is notified to the user as the first report. Therefore, for example, when establishing a communication link between the earthquake information distribution server SSV1 and the mobile communication terminals MS1 to MSk and transmitting emergency earthquake information, or distributing emergency earthquake information using e-mail via the Internet Compared to the case, emergency earthquake information can be distributed with less delay time.

  In addition, after the notification of the first report, the mobile communication terminals MS1 to MSk, based on the current position of the terminal and the received emergency earthquake information, the predicted seismic intensity scale at the current position and the arrival margin of the main motion The time and the convergence time are calculated, and this is notified to the user as the second and third reports. For this reason, the user can know the predicted seismic intensity scale at the position where he / she exists and the allowance time until the main motion arrives by the above second report. It is possible to take appropriate avoidance actions. Furthermore, since the convergence time can be confirmed by the third report even after the arrival of the main motion, anxiety until the main motion converges can be reduced.

  That is, in the first embodiment, the emergency earthquake information is first notified as the first report, and after the start of the notification of the first report, prediction calculation of the seismic intensity scale and the arrival time of the main motion is performed, and the calculation result is the first report. The second report is notified, and after the start of the second report, the prediction calculation of the convergence time is performed, and the result is notified as the third report. Therefore, after all the predicted seismic intensity scale, margin time, and convergence time have been calculated, the emergency earthquake information notification delay is kept to a minimum compared to the case where emergency earthquake information is reported together with these calculation results. Thus, real-time property can be maintained.

  In addition, the prediction calculations of the seismic intensity level, margin time and convergence time are all performed by the mobile communication terminals MS1 to MSk. For this reason, the earthquake information distribution server SSV1 only has to transmit the emergency earthquake information as the first report by a short message, and the function of the existing mail server can be provided without newly providing a special processing function in the earthquake information distribution server DSV. Can be implemented as is.

(Second Embodiment)
In the second embodiment of the present invention, when emergency earthquake information arrives from the earthquake observation network, the earthquake information distribution server first converts the format of the emergency earthquake information and transmits it to the mobile communication terminal by a short message. Next, the current location of the mobile communication terminal of the delivery destination is acquired, and based on the acquired current location of the mobile communication terminal and the received emergency earthquake information, the seismic intensity scale and main motion at the current location are acquired. Is estimated by calculation, and the calculation result is inserted into an e-mail and distributed to the mobile communication terminal. On the other hand, the mobile communication terminal receives the short message transmitted from the earthquake information distribution server, notifies the user of the emergency earthquake information as the first report, and subsequently receives an e-mail transmitted from the earthquake information distribution server. The display data of the earthquake detail information is generated based on the content of the received text, and this is notified to the user as the second report.

FIG. 7 is a block diagram showing a functional configuration of the earthquake information distribution server SSV2 according to the second embodiment of the present invention. In the figure, the same parts as those in FIG.
In the program memory 13, as an application program for carrying out the present invention, an earthquake information reception control program 13a, a first report delivery control program 13b, a position information acquisition control program 13b, an earthquake shaking time calculation program 13e, A detailed information distribution control program 13f is stored.

  Among these, the 1st report delivery control program 13b respond | corresponds to the earthquake information delivery control program of the said 1st Embodiment. That is, when emergency earthquake information is received from the earthquake monitoring server DSV, the distribution target area is set based on the earthquake occurrence position and the earthquake magnitude included in the emergency earthquake information, and exists in the set distribution target area. A user is selected from the user information database 14a. At the same time, the received emergency earthquake information is converted into a format corresponding to the short message, a short message in which the format-converted emergency earthquake information is inserted is generated, and the short message is selected above. To the user's mobile communication terminals MS1 to MSk.

  The location information acquisition control program 13b periodically accesses the user-registered mobile communication terminals MS1 to MSk and sends a location acquisition request during a period when no earthquake occurs, and is detected by the mobile communication terminals MS1 to MSk. The obtained current position information (latitude and longitude) of the terminal is acquired and stored in the user information database 14a. In addition, when the current location stored in the user information database 14a has not been updated for a certain period of time when the emergency earthquake information is received, a location acquisition request is sent to the mobile communication terminal to Get the current position (latitude and longitude).

  The earthquake shaking time calculation program 13e corresponds to the earthquake shaking time calculation function 32c described in the first embodiment, and the current position of the mobile communication terminal acquired by the position information acquisition control program 13b and the earthquake monitoring server Based on the emergency earthquake information received from the DSV, a predicted seismic intensity scale at the current position of the mobile communication terminal is calculated. Further, based on the current position of the mobile communication terminal and the emergency earthquake information, an allowance time until the main motion of the earthquake arrives at the current position of the mobile communication terminal is calculated. Further, based on the emergency earthquake information, a convergence time required for the main motion to converge is calculated. Then, the calculated predicted seismic intensity scale, margin time, and convergence time are stored in association with the corresponding user in the user information database 14a.

  The detailed information distribution control program 13f inserts or attaches the seismic intensity scale, margin time and convergence time calculated by the earthquake shaking time calculation program 13e as detailed earthquake information into the e-mail body, thereby distributing the mobile communication to be distributed. Send to the terminal.

  The mobile communication terminals MS1 to MSk receive the short message and the e-mail sent from the earthquake information distribution server SSV2, respectively. The emergency earthquake information inserted in the short message is displayed on the display unit 35 as the first report. In addition, when an e-mail is received, display data for notifying the details of the earthquake is created based on the detailed information inserted in or attached to the body of the e-mail. It displays on the display part 35 as 2nd report.

Next, the earthquake information distribution operation by the system configured as described above will be described. FIG. 8 is a sequence diagram used for the description. The system configuration is the same as that of the first embodiment, and will be described with reference to FIG.
When emergency earthquake information arrives from the earthquake monitoring server DSV, the earthquake information distribution server SSV2 first sets the distribution target area based on the earthquake occurrence position and the earthquake magnitude included in the emergency earthquake information in step 8b. Among the users existing in the distribution target area, the user who has applied for the distribution service is selected from the user information database 14a. This distribution target user is selected in units of areas based on the area information stored in the user information database 14a. For this reason, selection of users to be distributed can be performed in a very short time.

  At the same time, the earthquake information distribution server SSV2 converts the received emergency earthquake information into a format corresponding to the short message in step 8c. Then, a short message in which the converted emergency earthquake information is inserted is created, and this short message is transmitted to the selected user's mobile communication terminal (for example, MS1) as the first report. As described in the first embodiment, the short message service (SMS) is a simple mail transmitted using a protocol and a network unique to the carrier, and the time required from the creation instruction to transmission is as follows. Short and short transmission time. For this reason, it is possible to deliver in a short time with a small delay time compared to the case of using an electronic mail transferred via the Internet.

  On the other hand, when a short message arrives from the earthquake information distribution server SSV2, the mobile communication terminal MS1 first generates a sound or vibration in step 8d as shown in FIG. The information is displayed on the display unit 35 as the first report. At the same time, in step 8e, an emergency notification message indicating that the emergency earthquake information short message has been received is generated, and this message is transmitted from the BT I / F 40 to the wristwatch WT1 of the same user. When the wristwatch WT1 receives the emergency notification message, the wristwatch WT1 generates a sound or vibration and further blinks an emergency message reception icon. Therefore, even if the user does not have the mobile communication terminal MS1, it is possible to recognize the arrival of emergency earthquake information.

When the transmission of the short message is completed, the earthquake information distribution server SSV2 performs calculation for predicting the earthquake shaking time in step 8f as follows. FIG. 10 is a flowchart showing the processing procedure and processing contents.
That is, first, in step 10a, the mobile communication terminal MS1 to which distribution has been applied is selected from the user information database 14a, and the current position of the selected mobile communication terminal MS1 is read from the user information database 14a. If the read current position has not been updated for a certain period or longer, a position acquisition request is transmitted to the mobile communication terminal MS1, and the latest current position (latitude and longitude) of the terminal is acquired.

  Next, in step 10b, based on the read current position and the received emergency earthquake information, the seismic intensity scale at the current position of the mobile communication terminal MS1 is predicted by calculation. As described in the first embodiment, the predicted seismic intensity scale is a distance between the epicenter position included in the emergency earthquake information and the current position of the mobile communication terminal MS1 based on the earthquake magnitude indicating the intensity of the earthquake. It can be calculated by considering the distance attenuation according to R.

  At the same time, based on the read current position and the received emergency earthquake information, the absolute time at which the main motion (S wave) of the earthquake reaches the current position of the mobile communication terminal MS1, that is, the shaking start time is calculated. Predict by calculation. In addition, it may replace with absolute time and may calculate the allowance time until main motion (S wave) arrives at the present position of mobile communication terminal MS1. Furthermore, based on the earthquake occurrence time and the earthquake magnitude included in the emergency earthquake information, the stop time of the main motion (S wave) at the current position of the user is predicted. Note that, instead of the shaking stop time, the convergence time required for the main motion (S wave) to converge may be predicted.

  When the predicted seismic intensity scale, the shaking start time, and the shaking stop time are calculated, the earthquake information distribution server SSV2CPU 11 proceeds to step 10c, where the calculated predicted seismic intensity scale, shaking start time, and shaking stop are calculated. The time is associated with the corresponding user ID and stored in the user information database 14a.

  Further, the CPU 11 of the earthquake information distribution server SSV2 inserts or attaches the seismic intensity scale, the shaking start time and the shaking stop time predicted by the above calculation in the e-mail body as detailed information in step 8g shown in FIG. This electronic mail is transmitted to the mobile communication terminal MS1 to be distributed.

  On the other hand, when an e-mail arrives from the earthquake information distribution server SSV2, the mobile communication terminal MS1 creates display data based on the detailed information inserted or attached to the e-mail body in step 8h. Is displayed on the display unit 35. FIG. 11 is a flowchart showing the detailed information display processing procedure and processing contents.

  That is, the mobile communication terminal MS1 monitors the arrival of e-mail at step 11a. When an e-mail is received in this state, first, in step 11b, the predicted seismic intensity scale in the detailed information inserted or attached to the received e-mail body is displayed. Subsequently, in step 11c, the difference between the shaking start time in the received detailed information and the current time of the clock provided in the mobile communication terminal itself is calculated, and this calculated difference is displayed as a margin time in step 11d. When the display of the margin time is started, the mobile communication terminal counts down the margin time every second in step 11e, and displays the counted margin time. FIG. 6A shows an example of a display result in a period before arrival of the main motion (S wave).

  On the other hand, when the margin time becomes zero, the mobile communication terminal shifts from step 11f to step 11g, where the difference between the shaking stop time in the received detailed information and the current time of the clock provided in the mobile communication terminal itself. And the calculated difference is displayed as the convergence time of the shake in step 11h. When the display of the convergence time is started, the mobile communication terminal counts down the convergence time every second in step 11i, and displays the counted-down convergence time. FIG. 6B shows an example of a display result in a period after arrival of the main motion (S wave).

  Then, when the value after the countdown of the convergence time becomes zero, the mobile communication terminal shifts from step 11j to step 11k, and displays support information that is useful after the earthquake has converged. As support information, for example, inspection items of houses, nearby evacuation sites, supplies to be carried, and the like can be considered.

  As described above, in the second embodiment, when emergency earthquake information is transmitted from the earthquake monitoring server DSV, the emergency earthquake information is first short-circuited from the earthquake information distribution server SSV2 to the mobile communication terminals MS1 to MSk to be distributed. Delivered by message. Next, in the earthquake information distribution or server SSV2, based on the current position of the mobile communication terminals MS1 to MSk to be distributed and the emergency earthquake information, the seismic intensity scale at the current position of the mobile communication terminals MS1 to MSk, main The shaking start time and the shaking stop time are predicted by calculation, and these are distributed as earthquake detailed information to the mobile communication terminals MS1 to MSk to be distributed by e-mail.

  Therefore, emergency earthquake information can be distributed to the mobile communication terminals MS1 to MSk without causing a significant delay. That is, the real-time property of emergency earthquake notification can be maintained. In addition, following the distribution of the above-mentioned emergency earthquake information, the seismic intensity level, the start time of the main motion and the stop time of the main motion are distributed by e-mail, so that the user can grasp the details of the earthquake more accurately. This enables quick and appropriate action immediately before and during the main movement.

  Furthermore, in this embodiment, the earthquake information distribution server SSV2 performs prediction calculation of the seismic intensity level, the main motion shaking start time, and the shaking stop time. For this reason, the mobile communication terminals MS1 to MSk do not need to newly provide a special processing function, and basically only have a function of receiving a short message and an e-mail distributed from the earthquake information distribution server SSV2. There is an advantage that the existing configuration can be implemented.

(Other embodiments)
In each of the above embodiments, the mobile communication terminal itself calculates the current location of the mobile communication terminals MS1 to MSk based on the GPS signal, and transmits this current location information in response to a request from the earthquake information distribution servers SSV1 and SSV2. I made it. However, the present invention is not limited to this, the earthquake information distribution servers SSV1 and SSV2 access the mobile communication network control station, and the mobile communication control station acquires location information managed by the HLR (Home Location Register). Also good.

  Moreover, in the said 1st Embodiment, the earthquake information delivery server SSV1 demonstrated as an example the case where the user information database 14a which stores the information of all the subscriber users was provided. However, the present invention is not limited to this, and only the distribution target user may be extracted from all the users, and only the information related to the extracted distribution target user may be stored as the user information database. An example is shown in FIG.

  Furthermore, not only the latitude and longitude but also the height direction position may be included in the current position, and the predicted seismic intensity scale may be calculated in consideration of the height direction position. In this way, for example, when the user is present in a building, the hierarchy in which the user exists is estimated based on the position in the height direction, and the predicted seismic intensity scale can be corrected based on the estimation result. It becomes possible.

  In addition, the correction | amendment of the predicted seismic intensity scale according to the position of the said height direction is realizable as follows, for example. That is, a radio tag such as a radio tag that transmits information representing the number of floors is installed on each floor in the building, and the floor information transmitted from the radio sign is received by the mobile communication terminal. Then, the predicted seismic intensity scale is corrected by multiplying the predicted seismic intensity scale by a correction coefficient corresponding to the rank. It is also possible to calculate the height of the mobile communication terminal based on the GPS signal, replace the calculated height with the floor number of the building, and multiply the predicted seismic intensity floor by a correction coefficient corresponding to the floor number. It is possible to correct the predicted seismic intensity scale. In addition, the mobile communication terminal has a built-in or attached atmospheric pressure sensor, replaces the atmospheric pressure detected by the atmospheric pressure sensor with the floor of the building, and multiplies the predicted seismic intensity floor by the correction factor corresponding to this floor. The seismic intensity level can be corrected.

  Furthermore, when calculating the predicted seismic intensity scale, the region-specific ground amplification factor may be considered. The ground amplification factor is a value representing the degree to which the acceleration of vibration caused by an earthquake is accelerated or decelerated depending on the state of the ground near the ground surface. For the correction of the predicted seismic intensity scale in consideration of the ground amplification factor, a database storing the ground amplification factor corresponding to the position (latitude and longitude) is prepared, and the ground amplification factor corresponding to the position of the mobile communication terminal is stored in the database. Can be realized by weighting the predicted seismic intensity scale.

  Further, in the embodiment, the predicted seismic intensity scale and the margin time or convergence time are displayed separately. However, the predicted seismic intensity scale and the margin time or convergence time may be displayed integrally. For example, the margin time or the convergence time may be expressed by changing the size of the symbol figure for seismic intensity scale display shown in FIGS. This display method is particularly effective in a device with a small display size such as a mobile phone or a clock.

  Furthermore, in the above embodiment, the predicted seismic intensity scale, margin time, convergence time, and precautions are visually displayed on the display of the mobile communication terminal. Also good. This makes it possible for the user to grasp the predicted seismic intensity scale, margin time, convergence time, and precautions even in situations where it is difficult to visually recognize a visually impaired person or a display.

  In the above embodiment, the predicted seismic intensity scale, margin time, convergence time and precautions are displayed as detailed earthquake information, but when the epicenter is on the seabed and the current position of the mobile communication terminal is near the coast. May also display a warning message for a tsunami. At that time, the height of the tsunami may be estimated based on the earthquake magnitude and displayed together.

Further, in the embodiment, an emergency notification message is transmitted from the mobile communication terminal to the wristwatch, and a sound or vibration is generated in the wristwatch by this message. However, the present invention is not limited thereto, and emergency earthquake information may be transferred from the mobile communication terminal to the wristwatch and displayed as the first report. Further, the seismic intensity scale, margin time and convergence time obtained by the prediction calculation may be transferred from the mobile communication terminal to the wristwatch and displayed as the second report and the third report. FIG. 13 shows an example of the display result, 51 is a watch body, and 52 is a display unit.
In general, a wristwatch has a display size smaller than that of a mobile communication terminal. For this reason, it is better to convert the emergency earthquake information, margin time and convergence time into a watch format and transfer it.

  Furthermore, the external display device is not limited to a wristwatch, but can be applied to other portable electronic devices such as a portable audio player, a television receiver, and headphones, and is also attached to a display of a car navigation device, a household appliance, etc. A provided display, a television receiver, a personal computer, or the like is also applicable. The wireless interface for performing communication between the external display device and the mobile communication terminal is not limited to Bluetooth (registered trademark), but other weak or low power wireless communication methods such as wireless LAN, FM communication, Infrared communication or the like can be used.

  In addition, signals are exchanged between the mobile communication terminal and an external display device such as a wristwatch, regardless of whether or not emergency earthquake information has arrived. When it is detected that the alarm has occurred, an alarm message to that effect may be notified on an external display device such as a wristwatch. In this way, when the user is about to leave the mobile communication terminal on the desk or to be lost, an alarm message is notified on the watch, so that the user can prevent the mobile communication terminal from being left behind or lost. Can do. As a result, when emergency earthquake information arrives, this information can be surely notified to the user.

  In addition, an acceleration sensor is provided in the mobile communication terminal, an impact when the mobile communication terminal is dropped is detected by the acceleration sensor, and an alarm message to that effect is transmitted to an external display device such as a clock to notify the user. May be. In this way, it is possible to prevent the mobile communication terminal from being misplaced or lost.

  In addition, when it is detected that the distance between the mobile communication terminal and an external display device such as a wristwatch is longer than a certain length and it is impossible to send / receive signals, the function of rejecting the operation of the mobile communication terminal is provided. The mobile communication terminal may be provided. With this configuration, for example, a mobile communication terminal that has been misplaced or lost can be prevented from being used by a third party without permission, or stored data such as a telephone directory cannot be seen. In addition, while the function for refusing the operation of the mobile communication terminal is operating, for example, a message such as “This terminal is away from the ubiquitous watch, so functions other than incoming calls are stopped” is displayed or voiced. It is good to do so.

  In addition, the above-described operation refusal function for a mobile communication terminal can be similarly applied to a stationary personal computer, a fixed telephone, and a facsimile as well as a mobile communication terminal such as a mobile phone or a PDA. Further, the operation refusal function may be provided for office furniture such as desks, cabinets, and rockers. In this way, for example, when the user is away from the seat by a certain distance or more, it is possible to prevent a third party from opening the desk drawer, cabinet, locker, etc. without permission. The security of storage can be further increased.

  Further, in each of the embodiments, emergency earthquake information is distributed by a short message. However, cell broadcast may be used in a GSM (Global System for Mobile Communication) or cdma2000 system as an alternative to this short message. Moreover, in PHS (Personal Handyphone System), you may make it transmit emergency earthquake information using the area | region (for example, facility) which the user prepared in the call setup message can use. Furthermore, in general, a mobile communication system uses a broadcast channel for incoming call notification. If there is an area available to the user in the broadcast channel, emergency broadcast information is transmitted using this broadcast channel. Also good.

  Further, in each of the above embodiments, an automobile / mobile phone system has been described as an example of a mobile communication network. It is also possible to use it. In addition, the types and configurations of earthquake information distribution devices and mobile communication terminals, control procedures, and control details, as well as predicted seismic intensity scale, main motion shaking start time (or arrival allowance time), and shaking stop time (or convergence time) The calculation method etc.) can be variously modified without departing from the gist of the present invention.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
