Abstract

PURPOSE:To realize a backup system to effectively correspond to a case that a part to analyze the subscriber number, etc., of an emergency report terminal can not be used by providing a means to retrieve call originating place information based on the peculiar identifying information of the emergency report terminal. CONSTITUTION:When a reporter executes a disaster report through a terminal 12, an emergent report 25 is incoming through a public network 11 to a trunk circuit 17 in an emergency report receiving part 13 and detected by a CC 15 through a channel switch 14. Then, a pseudo-responding signal is returned from the trunk circuit 17 through the public network 11 to the emergency report terminal 12. The emergency report terminal 12 receives the pseudo-responding signal and sends a code number 26, which is peculiar for the terminal, and the code number is passed through the public network 11 and received through the trunk circuit 17 in the emergency report receiving part 13 to the CC 15. Continuously, the CC 15 executes incoming display from a trunk circuit 19 through the channel switch 14 to an incoming display 24 on a receiving stand 20. The operator of the receiving stand 20 confirms the incoming display of the incoming display 24 and executes response operation to the CC 15 of the emergency report receiving part 13 by a responding button 22.

Description

[Detailed Description of the Invention] [Summary] This invention relates to an emergency call reception system that receives emergency calls from terminals that are connected to a public network and accommodated in the public network. With regard to the backup method for searching for call location information based on the an emergency call reception means for receiving an emergency call from a terminal connected to the public network and accommodated in the public network together with unique identification information of the emergency call terminal; and an emergency call reception means connected to the reception means and received by the reception means. An emergency call reception system comprising a call place information search means for searching corresponding call place information based on unique identification information, and a call place information display means for displaying the search results, connected to the emergency call reception means, The emergency call terminal is configured to have a reception desk equipped with unique identification information display means for extracting and displaying the unique identification information of the emergency call terminal from the reception means.

(Field of Industrial Application) The present invention relates to a notification reception system that receives emergency calls from terminals connected to a public network and accommodated in the public TM, and more specifically relates to unique identification information of emergency call terminals. This invention relates to a bank-up method for searching source information based on .

[Conventional technology]

In general, 9B in the event of a disaster such as a fire! , in the report,
Due to its nature, more accurate reporting is required in a short period of time, but in reality it is extremely difficult to request this from whistleblowers. For this reason, against the background of recent advances in communication technology, the originating location display method has been introduced as a means to improve this problem.

As a conventional example, when the caller's terminal makes a call, the caller automatically sends a pre-registered terminal code, receives and analyzes it, and then informs the caller of the location where the disaster occurred. There is an emergency call reception system that can automatically identify the situation without any explanation.

In addition, the public network exchange where the caller is accommodated sends out the subscriber number of the call terminal, and by receiving and analyzing this, an emergency call reception system automatically identifies the disaster occurrence point in the same way as above. There is also.

In order to efficiently distribute the functions of the entire system, the above-mentioned emergency call reception system uses an ordinary private branch exchange or the like as a reception section that receives and receives emergency calls from the public network, and connects reporting terminals. In many cases, the system is structured in a distributed manner, with the analysis of the personal identification number being performed by a host computer, for example.

[Problem to be solved by the invention]

However, in the case of a function-distributed emergency call reception system as described above, the private branch exchange, etc. that receives emergency calls from the public network, and the host computer, etc. that analyzes the subscriber number of the reporting terminal, are connected via data lines, etc. Because they are often connected and are completely separate mechanisms, the host may be artificially stopped due to data line failure, host computer failure, or regular maintenance of the host computer. During this period, the entire emergency call reception system will stop functioning, making it impossible to fully develop its functions as a system with a strong public interest, and there is a problem that this could have a serious impact. .

SUMMARY OF THE INVENTION An object of the present invention is to realize a backup method that can effectively cope with the situation even if a part of an emergency call terminal that analyzes subscriber numbers, etc. is unavailable.

[Means for solving problems] FIG. 1 is a block diagram of the present invention.

The emergency call receiving means 5 is connected to the public Y11 and is a means for receiving the emergency call 5 report 3 from the terminal 2 accommodated in the public network L together with the unique identification information 4 of the emergency call terminal 2,
For example, a private branch exchange. In this case, the unique identification information 4 is, for example, the subscriber number of the emergency call terminal 2, and is automatically sent by the emergency call terminal 2 or sent by the exchange of the public network 1 that accommodates the emergency call terminal 2.

The transmission location information retrieval means 6 is connected to the emergency call reception means 5, and the reception means 5 receives! It is a means for searching for the corresponding call point information 7 based on the unique identification information 4 of the emergency call terminal 2, and is connected to a dedicated line circuit such as a private branch exchange, which is the emergency call reception means 5, via a data line or the like. This is the host computer that will be used. In this case, the combiator stores, for example, the addresses, names, building names, floors, floor plans, and other information of all the terminals 2 (subscribers) accommodated in the public network 1 as a database in the disk storage device. This is realized by a system that can be arbitrarily searched using the subscriber number, etc., which is the unique identification information 4. Further, the host computer may access a public directory assistance center or the like to search for the calling place information 7.

The origin information display means 8 is means for displaying the origin information 7 retrieved by the origin information search means 6, and is, for example, a CRT display device.

The reception desk 10 is connected to the emergency call reception means 5 and is equipped with a unique identification information display means 9 for extracting and displaying the unique identification information 4 of the emergency call terminal 2 from the reception means 5. The information display means 9 is, for example, an LED display that displays the subscriber number, and may also display the time and the like. In addition, reception desk 1
0 is connected to an arbitrary extension circuit of the private branch exchange, which is the emergency call receiving means 5. In this case, a display request button may be provided on the reception desk 10, and the unique identification information 4 may be displayed on the unique identification information display means 9 only when a request is made to the emergency report reception means 5 using the button. Furthermore, the number of reception desks 10 does not need to be one, and a plurality of reception desks 10 may be connected.

[For production]

In FIG. 1, during normal operation, the emergency call receiving means 5 is connected to the terminal 2.
After receiving the Emergency 1 Report 3 and the Emergency Identification Information 4 from
The origin information search means 6 searches for the corresponding origin information 7 based on the unique identification information 4, and displays the origin information display means 8.
to be displayed. This allows you to contact the corresponding fire department, etc.

Here, independent of the above operation, the unique identification information 4 received by the emergency call reception means 5 is sent to the reception desk 10 and optionally displayed on the unique identification information display means 9. Therefore, in the event of a failure in the data line connecting the emergency call reception means 5 and the transmission location information retrieval means 6, a failure in the host computer serving as the transmission location information retrieval means 6, or during routine 1.11 maintenance of the host computer. Even during periods when the transmission location information retrieval means 6 is artificially unavailable, such as, the reception desk 10
The worst situation can be avoided by searching for a form or the like prepared in advance by the staff based on the unique identification information 4 displayed on the unique identification information display means 9.

In this case, the reception desk 10 only needs to be connected to an extension circuit such as a private branch exchange, which is the emergency call reception means 5, and
The control for sending the subscriber number, which is the unique identification information 4, from the private branch exchange to the reception console 10 requires only slight changes to the control program in the private branch exchange, so it is possible to provide a sufficiently practical backup function at low cost. It can be realized.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a configuration diagram of the first embodiment.

The emergency call reception unit 13 is a private branch exchange (PBX),
A communication path switch 14 that performs circuit switching, a central control unit (CC1 and below) 15 that performs connection control, call control, etc.
A main memory (MM, hereinafter the same) 16 that stores control programs, call control data, etc., and various trunk circuits 17.
It consists of 19 mag on the 1st. The communication path switch 14 is connected to the public network 11 via the trunk circuit 17, and the emergency call 25 from the terminal 12 accommodated in the public 'II Mll is sent to the emergency call terminal 12 with a code number ( The subscriber number 26 is received by the CCl3 via the trunk circuit 17 and the call path switch 14, and the code number 26 is stored in the MM16.

Next, the number search unit 28 connects to the CCl 3 via the data line 27, the trunk circuit 18 in the emergency call reception unit 13, and the call path switch 14, and retrieves the code number 26 of the emergency call terminal 12 stored in the MM 16. This is the part where you input and search for the corresponding origin information 30. That is,
For example, in the disk storage device 31, addresses, names, building names, floor numbers, floor plans, and other information of all the terminals 12 (subscribers) accommodated in the public network 11 are stored as a database as transmission location information 30. , the number search unit 28 is a host computer that can arbitrarily search the database based on the code number 26, for example.

The CRT display 29 is a part that displays the origin information 30 searched by the number search section 28.

The reception desk 20 is connected to the CCl 3 via the trunk circuit 19 and the call path switch 14 in the emergency call reception section 13, and when the emergency call 24 is received by the emergency call reception section 13, the incoming call display 24 is connected to the reception desk 20. An incoming call is displayed, and by pressing S[]22 in response, CCl
3, an instruction is given to output the code number 26 of the emergency call terminal 12 stored in the iM16 to the number search unit 28. Further, by pressing the display request button 23, the code number 26 is inputted and displayed on the number display 21 of the LED display, which normally displays the line number and time of the trunk circuit 17. Note that the reception desk 20 is connected to a plurality of trunk circuits 1 in the emergency call reception section 13.
Multiple units can be connected via 9.

The operation of the first embodiment having the configuration shown in FIG. 2 will be explained based on the operation timing chart shown in FIG. 3.

First, when the caller uses the terminal 12 to make a disaster report,
The emergency call 25 from there arrives at the trunk circuit 17 in the emergency call receiving section 13 via the public network 11 (FIG. 3 31, see FIG. 3 below).

This incoming call is detected by the CCl3 via the communication path switch 14 or via a control line (not shown), and then the CCl3
Cl3 returns a pseudo response signal to the emergency call terminal 12 from the trunk circuit 17 via the public mll (S2).

Upon receiving the pseudo response signal, the emergency call terminal 12 sends out a predetermined terminal-specific code number 26 as an audio code within the line band (PB double signal is MF double signal), and reads this code. The number 26 is connected to the CCl via the public network 11 and the trunk circuit 17 in the emergency call reception section 13.
3 (S3).

Following this, the CCl3 is connected to the trunk circuit 19 via the communication path switch 14 or via a control line (not specifically shown).
The incoming call is displayed on the incoming call display 24 on the reception desk 20 (
S4).

The operator of the reception desk 20 changes the incoming call display on the incoming call display 24 to 6I.
If confirmed, press the response button 22 to press C of the report reception section 13.
A response operation is performed for Cl3 (S5).

In addition, as shown in FIG. 4, the CCl 3 sends the code number 26 along with the number 35 of the reception desk 20 that performed the response operation and the call number 36 (order) of the emergency call 25.
At the same time, it is stored in the MM 16 as received code storage data 34 and sent from the trunk circuit 18 to the number search unit 28 via the data line 27 (S6).
displays the line number of the trunk circuit 17 along with the time on the number display 21 on the reception desk 20 via the trunk circuit 19.

Having received the code number 26 and the reception desk number 35, the number search unit 28 searches the disk storage device 3 based on the code number 26.
Search the database above 1 and retrieve the pre-registered transmission location information 30 for each code number 26, that is, address, name, building name, number of floors, floor plan, and other information,
The information is displayed on the CRT display 29 compatible with reception desk number 35 (S7).

Normally, through the above operations, the operator of the reception desk 20 sees the displayed content and contacts the corresponding fire station, etc., thereby completing the disaster report.

On the other hand, the number search unit 28 may be artificially rendered unusable, for example, when there is a failure in the data line 27, a failure in the host computer that is the number search unit, or during periodic maintenance of the host computer. In this case, no display is made on the CRT display 29. The operation in this case will be described below based on the operation flowchart of FIG. 5 executed by the CCl3 of the emergency call reception unit 13 in addition to the operation timing chart of FIG.

First, the operator of the reception desk 20 requests a display of the reception desk 20 if the number search unit 28 is unavailable! By pressing 023, a display request is output to CCl3 of the emergency call reception unit 13 (S8 in FIG. 3, 5TEPII in FIG. 5).

On the other hand, after the CCl3 detects that the display request button 23 is pressed (TEP21 in FIG. 5), the received code accumulation data 34 in FIG. 4 in the MM16 corresponding to the reception desk number 35 of the reception desk 20 is 5 TEP 22 in FIG. 5).

Next, the retrieved received code accumulation data 34 in FIG.
If code number 26 exists in
6 is taken out and sent to the reception desk 20 via the trunk circuit 19. As a result, the code number 26 is newly additionally displayed on the number display 21 which has previously displayed the line number and time of the trunk circuit 17 (see FIG.
9, Fig. 5 5TEP24-5TEP25). in this case,
If the number of digits in the code number 26 is greater than the number of digits in the number display 21, the code number 26 can be divided and displayed by pressing the display request button 23 multiple times.

By the above operation, the operator of the reception desk 20
Based on the code number 26 displayed in 1, by examining the form corresponding to the code number prepared in advance, CR
It is possible to obtain information equivalent to that automatically displayed on the T-display 29, and it is possible to prevent the worst case scenario of not being able to respond to the emergency call 25, just by sacrificing some operability. Can be done (Figure 5 5TEP12)
.

In addition, as a back-up amplifier in this case, a code number compatible call location information search device is constructed using a personal computer or the like, and the operator of the reception desk 20 searches based on the code number 26, thereby further improving safety. be enhanced.

In addition, if it is determined in 5TEP24 of FIG. 5 that the code number 26 does not exist in the received code accumulation data 34 of FIG. , or because the trunk circuit 17 could not receive the code number 26, and the code number 26 could not be displayed on the number display 21, so the operator of the reception desk 20 could communicate with the caller at the terminal 12 by telephone. You just have to deal with it.

In the first embodiment described above, the reception console 20 only needs to be connected to the trunk circuit 19 of the call path switch 14 of the emergency call reception section 13,
The control for sending the code number 26 to the reception console 20 via the CCl3 requires only slight changes to the control program on the MM16 executed by the CCl3, thereby realizing a sufficiently practical backup function at low cost. Can be done.

Next, FIG. 6 is a block diagram of a second embodiment of the present invention.

The difference from the first embodiment shown in FIG. 2 is that the number search unit 2 in FIG. The section 28 searches a public directory assistance center 33 connected via a data line 32 to retrieve the origin information 30. The other parts are shown in Figure 1 in Figure 2.
Therefore, the overall operation of the second embodiment is also similar to the first embodiment. In the second embodiment, since the directory assistance center 33 is used, the cost required for number search can be reduced, and more general calling place information 30 can be searched.

In the first and second embodiments described above, the terminal 12 sends out the code number 26 by returning a pseudo response to the notification terminal 12, but the public network 12 that accommodates the terminal 12 The exchange within the terminal 12 may transmit the subscriber number corresponding to the terminal 12 as the code number 26.

(Effects of the Invention) According to the present invention, when there is a failure in the data line connecting the emergency call reception means and the transmission place information search means, when there is a failure in the host computer etc. that is the transmission place information search means, or when the host computer Even during periods when the source information search means is artificially unavailable, such as during regular maintenance, the unique identification information (subscriber code number, etc.) displayed on the unique identification information display means at the reception desk The worst situation can be avoided by searching for documents prepared in advance by the staff based on the information.

In this case, the reception desk only needs to be connected to an extension circuit such as a private branch exchange, which is the emergency call reception means, and the control for sending the subscriber number, which is unique identification information, from the private branch exchange to the reception desk is also simple. Since it is only necessary to slightly change the control program in the private branch exchange, a sufficiently practical backup function can be realized at low cost.
