[0011]
For example, as shown in FIG. 12, the telephone exchange 10 accommodates and connects an analog telephone terminal 1A such as an analog telephone for each port of a line circuit (LC) via a telephone line as an extension. As an extension, a digital terminal 1D such as a digital telephone is separately accommodated and connected for each port by an interface circuit (IF) via a digital line. In addition, many telephone exchanges 10 accommodate and connect a line circuit (LC) of the central office 2 for each port of a trunk circuit (TRK) via an analog subscriber line of the central office 2 at least as a part of an external line. are doing.
[0012]
The above-mentioned extension and external line are connected to the SW via the LC, IF, and TRK, and the central processing circuit (CPU) controls the SW using software stored in the memory circuit (MEM), and connects the internal line and the external line to each other. Connect.
[0013]
However, in the security system using the conventional telephone exchange device described above, the existing telephone exchange device cannot be used and rubbed as hardware equipment together with the telephone connected thereto. Therefore, there is a problem that work including hardware design and remodeling occurs, and the software processing is not sufficient.
[0014]
An object of the present invention is to solve such a hardware change problem and to provide a security system using a telephone exchange device that can construct a security system without changing the hardware of an existing telephone exchange device. is there.
[0015]
[Means for Solving the Problems]
A security system using a telephone exchange according to the present invention comprises connecting one telephone set to each port via one of a plurality of telephone lines as an extension and connecting at least one subscriber line via each port as an external line to the other. It is constructed without changing the hardware of the telephone exchange connected to the telephone exchange.
[0016]
Accordingly, each security sensor is connected to at least one of a line circuit, an interface circuit, or a trunk circuit in a telephone exchange, or an analog or digital line to establish a call connection for a predetermined outgoing or incoming call. It has a function that can request Further, the telephone exchange apparatus records the types of sensors connected corresponding to the line circuits, interface circuits, and trunk circuits to which the sensors are accommodated and connected, and the connection destinations in a memory circuit as a table, and As the destination, for example, an audible or visible display device is connected to an extension terminal, and a disaster prevention center, a security company, or the like is connected to an external line via an exchange network.
[0017]
Therefore, the telephone exchange apparatus is further provided with an information sending means for sending the detection information as audible or visible information to the display device of the connection destination in accordance with the type of the sensor, for example, an automatic message used for various services to the user. A response device, a message automatic transmission device, and the like are provided. That is, the telephone exchange having the central processing circuit (CPU) can notify the detection information received from the sensor to a predetermined display device or a security company by using the above-mentioned information transmission means by an appropriate program. The audible and visible information includes an e-mail, and the notification destination may be a mobile phone capable of receiving the e-mail.

[0021]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. In the drawings, only the portions related to the present invention are shown because there is a limit in size, and portions necessary for the device are also omitted.
[0022]
FIG. 1 is a functional block diagram showing an embodiment of the present invention.
[0023]
The illustrated telephone exchange device 10 includes an LC (line circuit) 11 having analog circuit loop monitoring, a TRK (trunk circuit) 12 for monitoring the power of the analog line, and a CPU (CPU) for controlling the functional operation of the telephone exchange device 10 as a whole. A central processing circuit) 13 and a message sending unit 14 capable of sending a message at the time of automatic response or the like in various telephone services.
[0024]
The telephone exchange apparatus 10 is the same as that shown in FIG. 12 described above. A telephone terminal is connected to the LC 11 via an analog telephone line as an extension for each port, and the TRK 12 is connected to an office exchange as an external line for each port. An analog subscriber line is connected.
[0025]
The LC 11 supplies power to the telephone terminal and monitors the loop of the telephone line. That is, a call from the telephone terminal is detected by forming a loop. Therefore, the sensor L1-A, which normally opens the loop and closes the loop when a sensor condition occurs, is connected to the port of the LC11.
[0026]
The TRK 12 is supplied with power from the central office and monitors this power. In the illustrated example, the sensor E2-A normally monitors the DC power supply, and detects the occurrence of the sensor condition by the disappearance of the power supply when the line is disconnected. However, the power supply may be another power supply other than the DC power supply, or may be generated when the power supply is supplied from the open circuit state in the sensing condition.
[0027]
The main operation procedure of the CPU 13 will be described later with reference to a flowchart.
[0028]
The message sending unit 14 receives the message signal instructed by the CPU 13 from the memory table 20 and sends it out according to the conditions corresponding to the connection destination. For example, when the connection destination display device is a personal computer (hereinafter, a personal computer). The message is a data code such as e-mail information prepared in advance, in addition to voice information and character information prepared in advance and provided with a code code.
[0029]
Further, depending on the display device, a combination of a plurality of these may be used, and the conditions can be set by software.
[0030]
Next, the memory table 20 will be described.
[0031]
The memory table 20 is formed in a part of the MEM (memory circuit) in FIG.
[0032]
The memory table 20 prepared for the security system of the present invention includes an extension connection table 21, an outside connection table 22, a sensor table 23, and a message table 24.
[0033]
FIG. 2 shows an embodiment of the extension connection table 21.
[0034]
The extension connection table 21 is searched by the CPU 13 when a call is made from an extension or a call to an extension, and an item is added to an extension table provided conventionally. In the extension connection table 21, a line type, a terminal device, an extension number, and the like are registered in advance for each port number A000- of the LC11. That is, it can be included as additional information in the conventional extension terminal information table.
[0035]
The line type includes an analog line for connecting a normal telephone capable of monitoring a two-wire loop, and a digital line for easily transmitting and receiving various data through constant connection.
[0036]
As the terminal device, an analog two-wire type single telephone can be cited, but as the connection device for the telephone line, a sensor that opens and closes a two-wire loop according to sensor conditions, and a voice message that is automatically received and received in an analog line as a sensor device. A speaker or the like for loudspeaking can be accommodated and connected. The extension number is used to call the terminal equipment by a dial number and to operate by connecting to the accommodated LC11.
[0037]
In the case of a telephone exchange device that connects a multifunctional telephone to a telephone line, such as a key telephone device, there are control lines or signal lines other than speech lines in the extension line, and sensors can be diversified. In the case of a digital line, a digital type multifunctional telephone can always exchange information with the telephone exchange, so that the sensor has a function compatible with this line to build a more multifunctional security system. can do.
[0038]
FIG. 3 shows an embodiment of the external line connection table 22.
[0039]
The external line connection table 22 is searched by the CPU 13 when an incoming call from an external line or a call connection request to an external line is made, and can be formed by adding items to a conventional external line information table. In the external line connection table 22, a line type, a connection model, a station line number, and the like are registered in advance for each port number B000 to TRK12.
[0040]
At each port of the TRK 12, the subscriber line of the central office is connected under the conditions of the subscriber terminal. That is, the central office usually monitors the loop formation at each port of the TRK 12 by the battery supply in the two-line analog subscriber line. Therefore, the TRK 12 opens the two-wire loop to monitor the battery on the central office exchange side.
[0041]
Therefore, the connection model is, for example, the LC of the station C. As the sensor, for example, a fire alarm with a built-in power supply is picked up. The office line number is, for example, a telephone number given to this subscriber line, and a call can be received via the office exchange using this telephone number.
[0042]
The example of port numbers C000 to C000 shown in the figure indicates digital lines such as ISDN (Integrated Services Network) and ADSL (Asymmetric Digital Subscriber Line). With these, it is possible to provide a sensor suitable for the conditions of the telephone terminal side of the digital line and to provide a route.
[0043]
FIG. 4 shows an embodiment of the sensor table 23.
[0044]
The sensor table 23 records information on sensors connected to the telephone exchange device 10. Therefore, when the terminal device or the connection model is a sensor when the CPU 13 detects a call or an incoming call and searches the extension connection table 21 or the outside line connection information 22, the CPU 13 searches the sensor table 23 to make a call. It is possible to know the mode of the sensor from the detected port number and the corresponding connection partner to which the sensor is notified of the sensitive information.
[0045]
Therefore, in the sensor table 23, for example, a sensor type, on-mode information, a reception extension number, a transfer destination code in the absence mode, a message code, and the like are registered in advance in correspondence with the port number. An outside line number, an e-mail (hereinafter, e-mail) address and the like are specified as the transfer destination code in the absence mode, and voice information, character information, e-mail data, and the like are specified as the message code. That is, an appropriate message can be transmitted in an appropriate information form such as voice information, character information, and e-mail data in accordance with the connection destination of each sensor.
[0046]
Although an e-mail address is shown in the e-mail area of the transfer destination code, an outside line number for dial-up is required for a normal subscriber line.
[0047]
In the illustrated table, for example, all of the voice, character, and E-mail of the message code are collected for one port. Code setting is also possible.
[0048]
For example, when a call is detected because the extension of the port number A006 is short-circuited from open to short-circuit and the loop is closed, the CPU 13 determines that the entrance door sensor has been activated based on the on-mode information and the sensor type. . The CPU 13 selects the message code “02” because the extension number “1211” of the reception destination is the speaker connected to the telephone line according to FIG. 2, and the message code of the next message table 24 corresponds to this sensor. You can select a message.
[0049]
In the absence mode transfer destination, for example, an outside line number of a predetermined security company that monitors sensor information during absence at home, nighttime security hours at an office, or the like is registered in advance. For this function, an automatic answering system, a call forwarding service, and the like provided in the telephone exchange can be used. In addition, in the case of a user who has a mobile phone capable of sending e-mail, which is very popular, it is desirable to send e-mail to the mobile phone. Therefore, according to the operation of the sensor, both the security company and the mobile phone can be called to notify the alarm state.
[0050]
FIG. 5 shows an embodiment of the message table 24.
[0051]
As shown in the figure, messages such as fire occurrence, detection of illegal intrusion from the entrance, and forgetting to lock a window are registered in advance in accordance with the message code. Sent to The message is created and stored by the terminal device of the connection destination with voice, text, and e-mail data. The delivery can be alone or simultaneous.
[0052]
That is, voices and characters are displayed on the multifunctional telephone. The mobile phone is capable of voice as well as e-mail. However, it is desirable to use only voice for the speaker and only e-mail for the personal computer. Of course, a voice can be attached by e-mail.
[0053]
Next, a security system using the above-described telephone exchange device 10 will be described with reference to FIG.
[0054]
The telephone exchange device 10 includes an LC 11, a TRK 12, a CPU 13, a message sending unit 14, a SW (switch) 15, a MEM (storage circuit) 16, and a fire notification unit 17. The LC 11, TRK 12, CPU 13, and message sending unit 14 The contents are the same as those already described with reference to FIG. Therefore, it is assumed that both the internal line and the external line are analog lines.
[0055]
As described above, the CPU 13 is connected to each circuit in the telephone exchange device 10 and controls its functional operation by exchanging information. That is, it is assumed that the telephone exchange device 10 has multiple functions such as a call forwarding function by automatic dialing and a message transmission function by an automatic response of the message transmission unit 14 in the ordinary telephone exchange function.
[0056]
The message transmitting unit 14 extracts a voice signal, a character signal, or an e-mail signal from the message table 24 based on an instruction indicated by a message code received from the CPU 13 and transmits the signal to a communication path. The voice signal is a voice message that can be heard by a receiver, an earphone, a speaker, or the like, the character signal is predetermined character data that can be displayed on a display panel, and the e-mail signal is data that can be e-mailed to a personal computer or a mobile phone. .
[0057]
Therefore, the e-mail signal is created by inserting the e-mail address indexed from the sensor table 23 into the destination address on the Internet. That is, the message sending unit 14 connects to the Internet using the dial-up external number indexed from the sensor table 23 for the external line selected by the CPU 13, and then sends the e-mail signal with the destination address inserted therein. Send to outside line.
[0058]
The SW 15 houses the LC 11, the TRK 12, the CPU 13, the message sending unit 14, and the fire alarm unit 17, and connects the communication channels under the control of the CPU 13. The MEM 16 includes the memory table 20 shown in FIG. 1, and further includes a program and a table for operation control, and a temporary memory area for operation. The fire notification unit 17 has a function equivalent to that of the message sending unit 14 and sends a fire notification other than a message to the alarm bell 6, for example.
[0059]
As shown in the figure, the telephone exchange apparatus 10 includes a window sensor 1-B on the extension and a fire alarm 2-B on the exterior, and a plurality of telephones 3 and one speaker 4 and a display panel on the extension. 5, the alarm bell 6, and the monitor 7 are connected and accommodated in the LC11.
[0060]
The window sensor 1-B has a contact which forms a loop of an extension line in an abnormal situation, similarly to the sensor L1-A described with reference to FIG. Like the sensor E2-A, the fire alarm 2-B also has a contact for cutting off the power supply in an abnormal situation. The telephone 3 forms a loop on the extension and makes a call, while receiving a call signal via the LC 11 when the loop is opened, rings the bell, forms a loop and responds to the incoming call to form a communication path. It has the usual function of being able to talk.
[0061]
The speaker 4 connected to the extension automatically answers when it receives a call, receives a voice message sent by the message sending unit 14 via a communication path, and broadcasts it. The display panel 5 receives the text message sent by the message sending unit 14 via the call path closed by the automatic response, and displays the text on the display screen.
[0062]
It is assumed that the alarm bell 6 activates the bell driving circuit upon receiving a calling signal and sounds the bell at a predetermined cycle. Also, the bell may ring in response to a call signal. Further, a buzzer may be used instead of the bell.
[0063]
The monitoring base 7 is prepared for maintenance operation and usually has a speaker and a display screen in addition to the telephone. In the case of a key telephone device, for example, a main general telephone is preferably a multifunctional telephone having a display panel. In the case of a private branch exchange, for example, a switchboard may be used.
[0064]
Next, with reference to FIG. 7 and FIGS. 1 to 6, a main procedure of the present system will be described according to an embodiment in which the window sensor 1 -B senses and receives the LC 11. To the port number “A001” of the LC 11, the window sensor 1 -B is connected to the extension by the extension connection table 21, and when the window sensor 1 -B is detected by the sensor table 23, the extension number “2221” is assigned. It is assumed that the telephone 3 is connected to the telephone 3 and the outside line telephone number "2345-6789" is called from the transfer destination code "01" in the absence mode.
[0065]
When the telephone exchange apparatus 10 accepts a call using the LC 11 (procedure S1), the CPU 13 searches the extension connection table 21 based on the port number "A001" of the call (procedure S2) and is connected as an extension terminal device. The response of the window sensor 1-B (NO in step S3) is determined.
[0066]
If this procedure S3 is "YES" and the calling terminal equipment is the telephone 3, a normal calling procedure for the telephone 3 (procedure S4) is executed.
[0067]
When the window sensor 1-B is searched from the port number (step S11), if the telephone exchange device 10 is set to the absence mode (YES in step S12), a predetermined call forwarding procedure (step S20) is performed. Be executed.
[0068]
If the above step S12 is "NO" and the operation on the extension side is requested, the CPU 13 searches the sensor table 23 for the extension number "2221" of the reception destination from the sensor table 23 by the port number "A001" of the caller. It is known from the extension connection table 21 that the connection destination is the telephone 3, and the telephone 3 of the corresponding terminal device is called based on the reception destination extension number "2221" (step S13).
[0069]
At the same time, the CPU 13 extracts the voice message code “03” corresponding to the telephone 3 which is the called terminal device from the extension connection table 21 (step S14). Next, the CPU 13 takes out a voice signal with the voice message code “03” from the message table 24 (step S15). At this time, there is no problem in transmitting information based on the character code "13" and the e-mail code "23" to the same communication path, except for the voice frequency band, but as described above, it is desirable to distinguish from the absence mode.
[0070]
Next, the CPU 13 receives the response from the telephone 3 (step S16), thereby connecting the communication path of the extension of the reception destination to the message sending unit 14, and the message code "03" received by the message sending unit 14 from the message table 24. Is converted into a voice message "The window is open" and transmitted to the telephone 3 (step S17).
[0071]
As a result, the user who has answered the call can hear the voice message “the window is open” from the handset of the telephone 3.
[0072]
If the telephone 3 is capable of receiving a character signal with a multifunctional telephone having a display screen, both the message codes "03.13" are extracted in step S14. In this case, the user can listen to voice from the receiver of the telephone 3 and read characters on the display screen.
[0073]
In the case where the extension number of the reception destination is “1211” and the speaker 4 is used, the voice message resounds indoors or on the premises when the speaker 4 automatically answers and connects the communication path to the message sending unit 14.
[0074]
Next, with reference to FIG. 8, a description will be given of a predetermined form of the procedure S20 in which the procedure S12 is “YES” and the telephone exchange apparatus 10 is set to the absence mode. The absence mode includes, for example, an automatic answering / recording mode at the time of absence in a key telephone device, and a night holiday mode in a private branch exchange.
[0075]
The CPU 13 receives the absence mode setting, searches the absence table transfer destination corresponding to the window sensor in the sensor table 23, and obtains the outside line number "2345-6789" from the transfer destination code "01" (step S21). It is assumed that this outside line transfer destination is a security reception desk of a security company that is outsourced, and has a speaker and a display panel.
[0076]
Next, the CPU 13 selects a free outside line, calls the outside line transfer destination by automatic dialing of the transfer destination outside line number (step S22), and, from the sensor table 23, the message code of the window sensor 1-B corresponding to the outside line transfer destination. "03.13" is extracted (procedure S23).
[0077]
Next, the CPU 13 extracts a voice message and a text message from the message table 24 based on the message code (step S24) and prepares for message transmission.
[0078]
When a response is received from an outside line (procedure S25), the CPU 13 connects an appropriate message sending unit 14 to the transfer destination outside line and repeats and sends a voice message according to a predetermined procedure, for example, after transferring character data (step S25). Step S26).
[0079]
Next, referring to FIG. 9 together with FIGS. 1 to 6, the main procedure of the present security system will be described according to an embodiment in the case where the fire alarm 2-B detects in the key telephone device and receives it in the TRK 12. explain. In the case of the key telephone apparatus, when there is no monitoring table 7, it is assumed that the main multi-function telephone corresponds, and the speaker of the monitoring table 7 is a receiver.
[0080]
This procedure is the same as that of FIG. 7 except that the target device is different. That is, as shown in FIG. 6, it is assumed that the fire sensor 2-B is connected to the external line port “B001” of the TRK12. When the fire sensor 2-B is detected by the sensor table 23, it is connected to a telephone circuit and a speaker provided on the monitor 7 of the extension number "2109", and in the absence mode, the emergency fire fighting is started from the transfer destination code "09". It is assumed that the telephone number “109” is called. In the case of a fire, the telephone exchange device 10 operates the alarm bell 6 in both the presence and absence modes.
[0081]
When the telephone exchange apparatus 10 receives an incoming call from an outside line at the TRK 12 (procedure S31), the CPU 13 searches the outside line connection table 22 by the port number "B001" of the incoming call (procedure S32) and sets the external line connection model. The response of the connected fire sensor 2-B (NO in step S33) is determined.
[0082]
If this procedure S33 is "YES" and the connection model of the called outside line is an exchange, a normal incoming call procedure for the exchange (step S34) is executed.
[0083]
When the telephone exchange device 10 is set to the absence mode when the fire sensor 2-B is searched from the port number “B001” (procedure S41) (YES in procedure S42), a predetermined absence transfer procedure (procedure S40) ) Is executed.
[0084]
If the above procedure S42 is "NO" and the operation on the extension side is requested, the CPU 13 searches the sensor table 23 for the reception destination extension number "2109" by the called port number "B001". The connection destination terminal device is known from the extension connection table 21 to be the monitoring console 7, and the monitoring console 7 is called based on the reception destination extension number "2109" (step S43).
[0085]
At the same time, the CPU 13 extracts the voice message code “01” and the character message code “11” corresponding to the monitoring console 7 as the called terminal device from the sensor table 23 (step S44). Next, the CPU 13 extracts a voice signal with the voice message code “01” and a text signal with the text message code “11” from the message table 24 (step S45). At this time, there is no problem even if the information based on the e-mail code "21" is transmitted to the same communication path, since the frequency is outside the corresponding frequency band.
[0086]
Next, the CPU 13 receives the response from the monitor 7 (step S46), thereby connecting the communication path of the extension of the reception destination to the message sending unit 14, and the message sending unit 14 sends a message table indicating that "a fire has occurred". The voice signal of the message received from 24 is converted to the voice of the message code “01” and sent to the speaker of the monitor 7, and the character signal is converted to the character of the message code “11” and displayed on the display screen of the monitor 7. It is sent (procedure S47).
[0087]
As a result, the user who responds to the call on the monitor 7 can hear the voice message “Fire has occurred” from the speaker, and can confirm the text message on the display screen.
[0088]
In the case of a fire, urgency is required. Therefore, it is desirable that the message sending unit 14 gradually increases the transmission level of the voice message "Fire has occurred". Also, by connecting the sound source of the fire alarm 17 to the speaker 4, the alarm bell 6, or the alarm buzzer, the sound can be transmitted indoors or on the premises.
[0089]
