Description

  The present invention relates to an m2m network technology for efficiently communicating object objectives, and more specifically, a network system in which a management server manages measurement data transmitted from a wireless terminal using a management database, and the like Communication method.

There are attempts to apply communication means not only for person-to-person but also for object objectives. This is called machine-to-machine, abbreviated m2m communication, and the network is called m2m network.
As specific examples of m2m communication, (1) the wireless built-in sensor reports the remaining amount (usage amount) of consumables managed by itself to the manufacturer's remaining amount management device, and (2) the healthcare device measures Report numerical values to health management devices such as health management centers.
Here, healthcare equipment includes vital data such as pedometers, sphygmomanometers, thermometers, weight scales, body fat scales, blood glucose meters, electrocardiographs, diet equipment, exercise equipment (exercise bikes, etc.). Refers to all devices that are numerically acquired.

As a network mainly used in m2m communication, there are a mobile phone and a PHS (registered trademark). A cellular phone transmission / reception device or a PHS (registered trademark) transmission / reception device is attached to an object (for example, a wireless built-in sensor), and the transmission / reception device calls and communicates with a communication partner. (Cell phones may be in packet switching mode instead of circuit switching mode.)
FIG. 7 shows a basic configuration of a PDC (second generation mobile phone) network (circuit switching mode) as an existing network mainly used in m2m communication (see Non-Patent Document 1).

  The network is composed of two levels, a mobile gateway relay level and a mobile subscriber level, and a home location register (HLR) is provided as a location registration database. As basic components, it has an interconnection function with other networks, an automatic tracking connection function for incoming calls, and a relay gateway mobile communication control station (MGC: Mobile Gateway Center), presence management and subscriber connection functions Subscriber mobile communication control station (MCC: Mobile Control Center), HLR in which subscriber information such as mobile terminal number and area of service is registered, base station (BS: Base Station) and mobile terminal (mobile device) ( MS: Mobile Station). Here, base station control functions (assignment of radio channels to mobile terminals, execution of switching control, etc.) are built in the MCC.

The outline of the procedure of (1) location registration, (2) outgoing call processing, and (3) incoming call processing, which are basic operations of the mobile communication network, will be described below.
(1) Location Registration In the mobile communication system using the cell system, since the mobile terminal itself moves spatially, it is necessary to keep track of its location on the network side. For this purpose, location registration is essential.

  As for the position of the mobile terminal, the PA is held in the HLR for each terminal in a paging area (PA) unit. Paging means wireless calling and is called a paging area because when an incoming call arrives at a mobile terminal, it is called all at once in the area. The basic process of location registration is as follows.

(i) In the mobile communication network, the PA number of the location is transmitted from the base station using a broadcast channel that can be received by all mobile terminals. The mobile terminal receives the PA number and stores it inside.
(ii) When a change in the PA number received by the mobile terminal after moving is detected, location registration is performed. The mobile terminal transmits a location registration request to the HLR, and the HLR rewrites the location information.
(iii) When the location registration is completed, a location registration completion signal is transmitted from the HLR to the mobile terminal.

(2) Outgoing process An outline of a basic connection procedure when making a call from a mobile terminal is shown below.
(i) The transmission terminal requests the BS to set a signal channel for transferring a call setting signal, and the BS sets the signal channel.
(ii) Dial the destination telephone number from the calling terminal and send a call setup request including the telephone number to the MCC via the BS. The MCC authenticates the terminal based on the subscriber information stored in the HLR.

(iii) The MCC instructs the BS to allocate a voice channel for a call to the calling terminal.
(iv) The MCC issues a call setup request to the MGC. If the destination is a fixed network or a mobile terminal of another operator, the MGC routes the call there. On the other hand, if the destination is a mobile terminal of a subscriber of his network, the location information is inquired of the HLR.
(V) When the connection destination is a mobile terminal, a call setup signal is routed based on the location information, and a simultaneous call is made from the BS in the paging area to which the receiving terminal belongs. When the destination that is the connection target responds, the connection is established and a call can be made.

(3) Incoming call processing An outline of a connection procedure when a mobile terminal receives an incoming call is shown.
(i) An incoming request (call setting request) from a fixed network or another cellular network is first delivered to the MGC, including the destination telephone number.
(ii) The MGC routes the call to the MCC to which the receiving terminal belongs. For this reason, the HLR checks in which MCC cover range the destination mobile terminal is located from the held terminal location information. Based on information from the HLR, the MCC makes a simultaneous call through the BS of the corresponding paging area.

(iii) The mobile terminal that has received the paging signal requests the BS to set a signal channel for transferring a call setting signal, and the BS sets the signal channel.
(iv) The MCC authenticates the receiving terminal based on the subscriber information stored in the HLR, sends a call setup request signal to the receiving terminal, and instructs the BS to assign a voice channel for calling to the terminal. Put out.
(V) When the receiving terminal rings and the called party answers, a connection is established and a call can be made.

In the circuit switching method, the wireless line is monopolized even when information is not actually flowing, so in the case of data communication where the actual data transmission time is shorter than the overall communication time, the efficiency of using the wireless line is Extremely worse.
On the other hand, in the packet switching method, since it is possible to wait for each packet, a wireless line can be shared by a plurality of communications, and the use efficiency can be increased also in data communications.

  A typical PDC-P (Packet) network configuration as a wireless packet system is shown in FIG. A packet gateway relay processing device (PGW: Packet Gateway Module) is a device for interconnecting with other networks such as the Internet and corporate networks. When a user packet arrives from another network, the mobile communication service control device (M-SCP) : Mobile-Service Control Point) location information, and has a function of routing to a packet subscriber processing device (PPM: Packet Processing Module) that manages the area where the mobile terminal exists.

The PPM is opposed to the mobile terminal via the base station, transmits / receives user packets, and has functions such as assembly / disassembly of packets in the wireless section, authentication, secrecy, and accounting.
In addition, in order to enable i-mode communication, a mobile message packet gateway device (M-PGW: Mobile Message-) that terminates the communication protocol with the mobile terminal and the server and connects them to each other. PGW) is arranged.
On the other hand, the i-mode server has a gateway function that connects the PDC-P network and the Internet. Specifically, it has an information distribution function, a mail transmission / reception function, a storage function, an information provider management function, and an information fee billing function.

The IP address of the user IP packet is associated with the telephone number of the mobile terminal by the PGW having a gateway function, and accesses to the M-SCP to acquire the location information of the mobile terminal and the connection processing is performed using it. If the position of the mobile terminal changes due to movement, the movement is controlled by re-tunneling the route.
As an example of m2m communication by a low-function terminal with short-range wireless, the m2m communication by a mobile phone is mainly in a wide area and outdoors, but the wireless tag (RFID) network proposed by Auto-ID A configuration example is shown in FIG.

  In the Auto-ID center concept, RFID functions are limited to significantly reduce the cost of tags (the target is 5 cents per item), aiming to give RFID to every product. The RFID itself is read-only and stores only a 96-bit ID (Electronic Product Code: ePC) including a serial number that enables individual identification. For example, a resolve function that commonly reads an ID (ePC) from an RFID attached to each individual through an RFID reader installed at a merchandise delivery destination and resolves the address of a database that stores data about each individual having the ID By (common resolver), the application program specifies the target database.

Then, data about each individual product with the ID read by the RFID reader is obtained from the database, or new data about the individual with the read ID is written into the database (for example, delivery date, Delivery location).

  However, in order for the target of m2m communication to be expanded from electrical appliances to general items, 1) commercial power cannot be used, so low power consumption is necessary. 2) Many targets of m2m communication From the viewpoint of low power consumption, effective use of frequency is necessary. 3) It is necessary to be able to apply to moving objects. 4) It is necessary to be able to receive messages such as control instructions. 5) Data There was a problem that it was necessary to delete heavy protocols and heavy network addresses as much as possible.

In other words, m2m communication is practical with advanced wireless terminals such as mobile phones, but the amount of data to be transmitted and received is small when managing the remaining amount of consumables at home and managing the measurement values necessary for healthcare. Therefore, the immediacy of management is not required, and there are a great variety of sensors and healthcare devices that add wireless functions.
For this reason, there is immediateness as in the prior art, and using an advanced wireless terminal equipped with inter-area handover is an overspec, which increases the price of healthcare devices and sensors, and makes it unnecessary for users. There is a problem of compulsory cost burden.

Further, the conventional method using a tag reader has a drawback that the communication distance between the reader and the RFID tag is short (in the case of special power saving, the communication distance is about 100 m).
For this reason, in the conventional tag reader model, the user installs the reader, or the user himself / herself moves consciously in the vicinity of the reader, or the administrator installs the tag reader where the user always passes There was a need to do.

For example, in the case of a health care system, a reader is provided at a convenience store or a ticket gate of a station, a wireless tag function is added to a pedometer, and a wireless tag function is also provided to a scale, a blood pressure monitor, and the like. Then, the measurement values of the weight scale and the sphygmomanometer are transmitted to the pedometer, and each measurement value is stored in the pedometer. The user attaches the pedometer and stops at the convenience store when taking a walk. The measured value data stored in the pedometer is read or the measured value data is read by a reader provided at the ticket gate during commuting.
Therefore, it is necessary to install a tag reader by imposing some positional burden on the user or by an administrator who installs the tag reader being familiar with the user's behavior.

In addition, for tags that do not have a reception function, the user must manually adjust the time or add a radio clock function in order to accurately adjust the time when adding data with a time stamp. There is.

Hereinafter, a network system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a network system according to the embodiment.
In this figure, a wireless base station 1 is composed of a wireless transmission / reception unit that performs wireless communication (data transmission / reception) with a wireless terminal 2 and a data transmission / reception unit that performs data communication (transmission / reception) with a communication server 3. .
The wireless terminal 2 transmits a communication request (including its own terminal ID) to the wireless base station 1. When the wireless transmission / reception unit receives communication request data as an access by wireless communication from the wireless terminal 2, the data transmission / reception unit transmits the communication request data received by the wireless transmission / reception unit to the communication server 3.
The communication server 3 identifies the terminal based on the terminal ID included in the input communication request data, and determines whether or not to accept the communication request (determined based on whether the service is in service or a fee is paid). If the communication server 3 determines not to accept the communication, the communication server 3 disconnects the communication. If the communication server 3 determines to accept the communication, the communication server 3 transmits a communication permission to the wireless terminal 2 via the wireless base station 1. Further, the radio base station 1 performs communication scheduling, determines a time slot for the radio terminal 2, and notifies the radio terminal 2 of the terminal ID and the slot number.
The wireless terminal 2 transmits data to the wireless base station 1 using the slot having the slot number assigned in the wireless base station 1.

Then, the radio base station 1 transmits a communication request from the radio terminal 1 to the communication server 3 by associating transmission data with the terminal ID from the terminal ID and the number of the transmitted time slot.
When the communication server 3 receives the transmission data (packet shown in FIG. 2A) transmitted by the wireless terminal 2 via the wireless base station 1, the terminal ID is registered (stored) in the database 4. Detect whether or not.
In the data transmission described above, the wireless terminal 2 uses an authentication key provided in advance by a network administrator in the transmission data packet together with the transmission data and encrypted data (message authentication code) using an encryption key set for each wireless terminal. To do. The result of hashing the authentication key, the transmission data, and the encryption key set in the wireless terminal is defined as encrypted data (message authentication code). Then, the wireless terminal 2 includes the encrypted data in the transmission data and transmits it to the communication server 3 via the wireless base station 1.

  The database 4 shows the correspondence between the base station ID of the radio base station 1 (or the paging area ID for identifying the paging area of the radio base station) and the server ID of the communication server 3 that manages the radio base station 3. FIG. The base station table of (a) is stored. Further, the database 4 includes a terminal ID of the wireless terminal 2, a base station ID (or paging area ID) of the wireless base station 1 that the wireless terminal 2 is a communication target (existing in a distance range), and each wireless terminal 2. The terminal table shown in FIG. 3B is registered, which shows the correspondence between the encryption key data set in (2) and the destination address (for example, URL) of the destination set for each wireless terminal 2.

Further, the communication server 3 uses the encryption key and the authentication key extracted from the terminal table in correspondence with the terminal ID of the wireless terminal 2 using the encryption key included in the transmission data from the wireless terminal 2 and The encrypted data (message authentication code) is decrypted with the encryption key, and it is verified whether or not the authentication key matches the transmission data.
Alternatively, the communication server 3 hashes the authentication key and the transmission data and the encryption key set in the wireless terminal, and verifies whether or not it matches the encrypted data (message authentication code) transmitted from the wireless terminal 2. .
Then, if the communication server 3 confirms that the transmission data matches and is transmitted properly by the verification, the communication server 3 determines that the wireless terminal 2 has been authenticated and transmits the transmission data to the gateway (GW) 5. To do.
The gateway (GW) 5 extracts the terminal ID included in the transmission data, refers to the terminal table of the database 4, extracts the transmission destination address corresponding to this terminal ID, and uses this transmission data as the transmission destination address. Then, the data is transmitted via the information communication network I.

The information communication network I includes a public data communication network, a dedicated data communication network, and the Internet.
The management server A of the management company 6 pointed to by the transmission destination address and the management server 7A of the management company 7 each measure the measurement data included in the transmission data transmitted by the wireless terminal 2 in the management database 6B or the management database 6B. It is registered and managed in the database 7B, and various data processing is performed with this measurement data.
As shown in FIG. 4, the management databases 6B and 7B store terminal IDs, GW addresses, measurement data, time data, determination data, and determination results in correspondence with individual IDs. Yes.

  When a product to which the wireless terminal 2 is added, that is, a product managed by the management company is purchased, the terminal ID of the wireless terminal 2 corresponds to the personal ID that identifies the purchased user, and the management database 6B (or management) Register in the database 7B). At this time, the ID is registered in the terminal table of the database 5 corresponding to the GW 5. The registration process described above is performed by an administrator who performs maintenance of each database. Since the wireless terminal 2 may be owned by a plurality of specific homes and individuals or used by a plurality of users, it is necessary to specify measurement data with a personal ID.

Next, the operation of the network system according to the embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a flowchart showing an operation example of the network system according to the embodiment.
In the following description, for example, the management company 6 is a health management center that manages the health of the user, and the wireless terminal 2 is mounted on a healthcare device. Here, the health care device is a pedometer that detects the number of steps taken, a sphygmomanometer that measures blood pressure, a thermometer that measures body temperature, a weight meter that measures body weight, a body fat meter that measures body fat percentage, and a height Vital data to measure health such as calorie amount consumed by height meter to measure, blood glucose meter to measure blood sugar level in blood, electrocardiograph to measure electrocardiogram data, diet equipment and exercise equipment (exercise bike etc.) It refers to all devices that acquire numerically. At this time, the wireless terminal 2 transmits the measured measurement data as transmission data to which various kinds of data described above are added in the period or measurement set inside corresponding to the usage application of the added device. .

Also, for example, the management company 7 is a consumable sales company that manages the remaining amount of consumables used by the user, and the wireless terminal 2 is the remaining amount of each consumable that is installed in each consumable container. It is connected to a detection sensor configured to measure.
Here, the detection sensor for measuring the remaining amount of consumables is a detection sensor for measuring the distance from the top of the tank to the oil level in the oil tank. There is a detection sensor for detecting whether or not the powder is lower than the detection position of the sensor, a detection sensor for detecting whether or not the powder surface of sugar, salt, pepper and the like is lower than the detection position of the sensor. At this time, the wireless terminal 2 transmits the measurement data of the remaining amount as transmission data to which the various types of data described above are added in a cycle set internally in accordance with the usage application of the added device. To do.

In the following description, it is assumed that the transmission destination of the transmission data of the wireless terminal 2 is the management server 6B of the management company 6. In the management database 6B, it is assumed that terminal IDs A101, A102, and A103 correspond to the same personal ID (for example, all personal IDs correspond to P101). In FIG. 4, the wireless terminal 2 with terminal ID · A101 is connected to a weight scale, the wireless terminal 2 with terminal ID · A102 is connected to a body fat scale, and the wireless terminal with terminal ID · A103 is connected to a blood glucose meter. Also, the personal ID · 156 corresponds to the terminal ID · A115, the personal ID · 106 corresponds to the terminal ID · A116, the personal ID · 107 corresponds to the terminal ID · A117, and the terminal ID and the personal ID correspond one-to-one. There are also configurations. Further, there is a configuration in which personal IDs P112, P113, and 114 correspond to the terminal ID 111, that is, a plurality of personal IDs correspond to one terminal ID.
Further, the communication server 3 transmits time data (year / month / day / hour / minute / second) as broadcast data to the wireless terminal 2 via the wireless base station 1 at regular intervals. To do. Thereby, each wireless terminal 2 adjusts the time of the internal timer and synchronizes the time with the communication server 3.

In step S1, when the wireless terminal 2 having the terminal ID · A101 detects that the time of a preset period (for example, 11:00 pm, once a day) is reached, the transmission data is transmitted to the management server 6B. Therefore, transmission request data is transmitted to the radio base station 1.
In the wireless communication station 1, the wireless transmission / reception unit receives the transmission request data, and the data transmission / reception unit transmits the transmission request data to the communication server 3.

  In step S2, when the transmission request data is input, the radio base station 1 extracts the terminal ID from the transmission request data, and the communication timings with the other radio terminals 2 match based on the extracted terminal ID. In order to prevent transmission data from colliding, an empty slot number is extracted from the time slot of the radio base station 1 communicating with the radio terminal 2 (scheduling). Then, the radio base station 1 transmits the extracted slot number to the radio terminal 2. Thereby, the negotiation between the communication server 3 and the wireless terminal 2 ends. At this time, the wireless terminal 2 transmits the transmission request data to a negotiation slot in a preset time slot. At this time, when there is a collision with transmission request data of another wireless terminal 2 or there is no empty slot, there is no notification from the communication server 3 and no response data is transmitted after a set waiting time (for example, 500 ms). The transmission request data is transmitted again.

Next, in step S3, the wireless terminal 2 having the terminal ID A101 receives the packet configuration shown in FIG. 2B, that is, the weight measurement data stored in the internal storage unit, the time data indicating the measured time, and the authentication process. The encrypted data used for the transmission is transmitted as transmission data in the slot of the designated slot number. Here, if time data is not required, the packet configuration shown in FIG. 2A may be used as transmission data.
In addition, when the family scale is shared by the family and each receives a health management service at the health management center, each family member who uses the personal weight has a personal ID and is registered in the management server 6B. For this reason, as shown in FIG. 2B, the packet configuration is such that the measurement data can be identified by the personal ID.
For example, as described above, when a weight scale is shared by a family (a plurality of users), when measuring the weight, the user himself / herself presses a button for selecting a user attached to the weight scale. After selecting, take the weight scale and measure the weight. At this time, the weight of the user is stored in the scale together with the personal ID (set corresponding to the above button). Alternatively, the user can carry a USB key, RFID, etc. that can recognize the user himself and insert the USB key into the scale, or read the RFID with an RFID reader built in the scale, so that the personal ID can be obtained. You may make it recognize.

Next, in step S4, when the communication server 3 inputs the transmission data via the radio base station 1, the communication server 3 extracts a terminal ID from the transmission data, and the same terminal ID is registered in the terminal table of the database 4. If it is not registered, the process proceeds to step S8.
Next, in step S8, the communication server 3 discards the transmission data and stops communication with the wireless terminal 2.

  On the other hand, when it is detected in step S4 that the terminal ID of the wireless terminal 2 that has transmitted the transmission data is registered in the terminal table, the communication server 3 extracts the encrypted data from the transmission data. And the communication server 3 reads the encryption key data memorize | stored corresponding to terminal ID of this radio | wireless terminal 2 from a terminal table, decodes the said encryption data with this encryption key, this decoded data, The setting data provided to the wireless terminal 2 in advance is compared to detect whether or not they match.

  As a result of the detection process, when the communication server 3 detects that they do not match, the communication server 3 advances the process to step S8 assuming that the authentication has failed. On the other hand, when the communication server 3 detects that they match, the data described in the base station ID column of the terminal table matches the base station ID of the radio base station 1 that is the communication partner of the radio terminal 2. If it matches, the terminal table is not processed as it is, and the process proceeds to step S5. On the other hand, the communication server 3 determines whether any data is described in the base station ID column of the terminal table, the data described in the base station ID column of the terminal table, and the communication partner of the wireless terminal 2. When the base station ID of the wireless base station 1 is detected to be inconsistent, the base station ID of the wireless base station 1 with which the wireless terminal 2 is currently wirelessly communicating is entered in the base station ID column of the terminal table. The writing and processing are advanced to step S5.

Next, in step S <b> 5, the communication server 3 transmits the transmission data received from the wireless terminal 2 with the terminal ID • A101 to the GW 5.
Thereby, in step S6, the GW 5 reads the transmission destination address corresponding to the terminal ID · A101 from the terminal table, and sends the transmission data received from the wireless terminal 2 of the terminal ID · A101 to the read transmission destination address, that is, It transmits to the management server 6A via the information communication network I.

  Next, in step S7, when the received transmission data has the configuration shown in FIG. 2B, the management server 6A has a one-to-one correspondence between the personal ID and the terminal ID. And the measurement data and time data are written in the management database 6B in correspondence with the extracted terminal ID. On the other hand, when the received transmission data has the configuration of FIG. 2C, the management server 6A writes (records) the measurement data and time data in association with both the personal ID and the terminal ID.

Then, the management server 6A reads the determination data corresponding to the terminal ID (and personal ID) in the management database 6B, and whether or not the measurement data exceeds the predetermined determination data, for example, the weight indicates the determination weight. Judgment is made as to whether or not it exceeds, and the comparison result with the judgment data is written in the judgment result column. Further, when there is the same measurement data, the management server 6A merges these measurement data into one measurement data. At this time, the time is changed as a time range including all merged measurement data.
Further, the management server 6A records changes in measurement data in time series as a history, records them in the management database 6B in correspondence with terminal IDs (and personal IDs), and records them in units of time data. Even when it is detected that the change rate set in advance is exceeded, this result is written in the determination result column.

Furthermore, not only the body weight but also the measurement data of the other vital data measuring devices in the health care device such as the body fat meter, the blood pressure meter, the thermometer, and the electrocardiogram data, the management server 6A also records the measurement data in time series. And recorded in the management database 6B.
Then, the management server 6A compares the result of data processing for comparing with a data evaluation specialist or past statistical health data with a standard value at a predetermined cycle (for example, once a month). The graph notifies the user of changes in the time series of the measurement data, along with health management advice, by e-mail to a mobile phone or PC. The user's e-mail address is registered in advance in the management database 6B corresponding to the terminal ID (and personal ID). Thereby, when a user becomes sick, the user can look back on the lifestyle and health state up to now, and can use it for a medical examination by a doctor.

  In addition, the management database 6A takes a history of the number of steps and calories measured by a pedometer, a diet device and an exercise device in a health care device, takes a history of the amount of exercise of each user, and compares the results with other users. The data is processed to improve the will of the user who exercises.

  When the transmission destination of the transmission data of the wireless terminal 2 is the management server 7A, since it is a consumable sales company such as a cosmetic company or an oil company, the management server 7A stores the measurement data in the management database 7B for each terminal ID. And a difference with the measurement data from the previous time is obtained, and a history for each terminal ID is left in the management database 7B as time-series data. As a result, changes in consumption of cosmetics and oil over time (consumption trend survey) or seasonal changes in consumption (acquisition of statistical data on consumption by season) can be monitored by the sales company (or manufacturing company). Very important data can be obtained as a marketing survey. Conventionally, the user (consumer) himself has to record the consumption amount on the questionnaire sheet, and the cost for the questionnaire survey is high, and it is difficult to acquire data for taking sufficient statistics. However, with the above-described configuration of the mobile phone, it is possible to obtain a large amount and accurate consumption of consumables at an easy cost, which can greatly contribute to a marketing survey.

  When the management company that is the transmission destination of the transmission data of the wireless terminal 2 is a consumables sales company that supplies consumables, the management server A is preset with measurement data indicating the remaining amount in the transmission data. When comparison with the determination data is made and it is detected that the measurement data is smaller than the determination data, “replenishment required” is written in the determination result column corresponding to the terminal ID of the management database 7B. When it is detected that the remaining amount is large, “no replenishment necessary” is written in the determination result column. At this time, the wireless terminal 2 transmits measurement data, for example, once a day. Then, the management server 7A detects whether or not “replenishment required” is recorded in the determination result column of the management database 7B once a week in a preset cycle.

Next, when the management server 7A detects a determination result field in which “replenishment required” is recorded in the management database 7B, the management server 7A extracts the corresponding personal ID, and from the customer table recorded in the management database 7B, The e-mail address of the PC or mobile phone corresponding to the personal ID is read, and an e-mail notifying whether or not an order is necessary is sent to the user. The user looks at the e-mail from the consumables sales company, confirms the remaining amount of consumables, and determines whether to place an order. As a result, the user can be urged to place an order, and the consumables sales company can efficiently accept consumables.
As described above, the management server 7A compares the measurement data with a predetermined value set in advance, and notifies the wireless terminal 2 of the comparison result.

When the wireless terminal 2 does not have a built-in timer, the measurement data is added to the transmission data at the time of measurement, and is transmitted according to the packet configuration of FIG. Then, it may be transmitted to the management server as the packet configuration of FIG.
Further, each wireless terminal 2 may be designated from the communication server 3 at a timing for transmitting transmission data.

  That is, each wireless terminal 2 is registered in the terminal table of the database 4 (by data indicating which wireless base station 1 is in communication range) unless it moves. For this reason, the communication server 3 schedules the time and notifies each wireless terminal 2 in advance of the slot number of the time slot that starts at the specified time, so that the transmission request data from each wireless terminal 2 is transmitted. It is possible to efficiently transmit / receive data to / from each wireless terminal 2 without collision.

  Each radio base station 1 is arranged such that the radio communicable ranges where radio waves reach overlap and the radio communicable ranges are continuous. At this time, different frequency channels are used for data transmission / reception in order to prevent communication interference between adjacent radio base stations 1. For this reason, for example, if the wireless terminal 2 is provided in a pedometer, it is a mobile body in which a user walks and moves, and from the communication range of a certain wireless base station 1 When moving to the communication range of the wireless base station 1, it is necessary to change the frequency used for wireless communication.

For this reason, the wireless terminal 2 supports a plurality of frequency channels, and receives a pilot signal or the like from the wireless base station 1 at each frequency when performing or performing communication, and receives the highest reception strength. After detecting a frequency with a strong (radiowave reception intensity) and selecting a frequency channel for data transmission / reception based on the detection result, data transmission / reception with the radio base station 1 is performed.
As a result, according to the above-described embodiment, unlike the mobile phone, since the handover process is not performed, when changing the radio base station during the data communication, the data communication needs to be performed again, but m2m (machine to machine A system between machines), and the amount of data for one data communication is as small as a few hundred bytes at the maximum, so that communication can be easily performed again.
In the above-described embodiment, since the amount of data to be transmitted / received is small and the communication frequency is not high, the possibility of changing the radio base station during data communication is low. There is no need to perform a handover process that is performed because communication is not interrupted, unlike a mobile phone.

  In the embodiment shown in FIG. 1 described above, the wireless terminal 2 has been described as being added to the measurement device and the measurement target, respectively. However, the wireless terminal 2 is not added to the measurement device. For example, each home electric appliance to be measured communicates with the wireless terminal 2 using wireless, wired, and infrared, and the measurement data received by the wireless terminal 2 is used as transmission data. A configuration according to another embodiment that transmits to the management servers 6A and 7A may be employed. In the other embodiment, after the wireless terminal 2 receives the measurement data from the measurement device, the communication between the wireless terminal 2 and the management servers 6A and 7A (hereinafter referred to as management server) has been described above. The same process is performed. For this reason, the description of data transmission / reception between the wireless terminal 2 and the management server is omitted. In addition, the communication using the infrared rays from the measuring device is a data format in a format used for remote control (control of television, stereo, etc.) of home appliances (home appliances). At this time, a transmission switch for transmitting transmission data is provided to the measurement device, and when the user presses this switch, when the measurement device detects that the transmission switch is pressed, the measurement data is transmitted to the wireless terminal 2. Also good. In addition, a control signal instructing to transmit transmission data to the measuring device is transmitted from the wireless terminal 2 periodically or by user operation, the measuring device receives this control signal, and the control signal for itself is transmitted. It is also possible to detect the presence by the identification information included in the control signal and transmit the measurement data.

  That is, the wireless terminal 2 uses the home appliance data format received from the home appliance, that is, a data format specific to a home appliance (measuring device such as a scale or height meter) defined by the Japan Home Appliances Association (see FIG. 6). Then, the measurement data is directly included in the transmission data and transmitted to the management server. In FIG. 6, the packet of the home appliance data format includes a reader unit, a custom code unit including company information of a 15-bit manufacturing company, a 4-bit parity unit, a 4-bit data code unit, data Part and a trailer part, and the packet length is variable length up to 48 bits.

In the table of the management database (6B or 7B) shown in FIG. 4, an analysis program (application program) corresponding to the data format of home appliances is set for each terminal ID or individual ID in addition to the configuration of the embodiment. ing. That is, an analysis program is set corresponding to the terminal ID or personal ID.
Then, the management server selects and loads the analysis program corresponding to the terminal ID or personal ID added to the transmission data, and executes it. This application interprets the data format, and the measurement data in the data portion of the transmission data. At the same time as reading, the measurement data corresponding to the application is processed. For example, if the measurement data is a weight scale, the measurement data includes body weight, body fat percentage, and the like, and an analysis program for calculating the degree of obesity using a preset height is set ( As an example, a determination process such as whether or not the degree of obesity is normal is performed).

Further, in the table of FIG. 4, it is not always necessary to set an analysis program corresponding to all terminal IDs and personal IDs, and only those that need to be processed by the analysis program may be set. . In this case, when the transmission data is transmitted, the management server detects whether or not an analysis program is set corresponding to the terminal ID or the personal ID.
When the management server detects that the analysis program is set, the management server extracts the measurement data from the transmission data, performs calculation processing by the analysis program, and stores the calculation processing result corresponding to the terminal ID or personal ID. To do. On the other hand, when the management server detects that the analysis program is not set, it extracts the measurement data from the transmission data and stores the measurement data in correspondence with the terminal ID and the personal ID.

Furthermore, in the table of FIG. 4, not only the analysis program but also a transfer address may be set corresponding to the terminal ID or personal ID.
In this case, the management server not only accumulates the calculation result of the analysis program in the management database, but also if the transmission address is set for the corresponding terminal ID or personal ID, Thus, the calculation processing result or measurement data by the analysis program may be transmitted as it is. For example, if the transfer address is analyzed by another analysis program or if the format of the measurement data received by itself cannot be recognized, another server having an analysis program that analyzes the measurement data Points to the address. That is, when the management server cannot analyze the home appliance format, the measurement data is transferred as it is (in the form of the data format) to another management server that can analyze the home appliance format.

With the configuration of the above-described other embodiment, the system according to the embodiment is improved by improving the software so that the measurement data is transmitted to the wireless terminal 2 without the need for hardware modification such as existing home appliances. Can be used.
In addition, with the configuration of the other embodiment described above, it is not necessary for the wireless terminal 2 to have a function of interpreting the data format of the measurement data, and the analysis set in the management server by the network described in the embodiment. The measurement data can be analyzed by the program, and the calculation processing result and the measurement data can be managed by the management database.
Furthermore, with the configuration of the other embodiments described above, the wireless terminal can be reduced in size, reduced in power consumption, and functions can be shared regardless of the type of home appliances to be connected.

  It should be noted that the programs for realizing the functions of the wireless terminal 2, the communication server 3, and the management servers 6A and 7A in FIG. 1 are recorded on a computer-readable recording medium, and the program recorded on the recording medium is recorded.
