Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to 119 notification line response control of a fire fighting communication command system, and more particularly to a response system using a general telephone in an emergency of the system side.

[0002]

2. Description of the Related Art Since a conventional fire fighting communication command system cannot respond to a 119 reporting line by a general telephone, it has an emergency device for an emergency of the system side such as a failure of the command system. All 119 reporting lines are switched and accommodated on the emergency equipment side from
The incoming call was displayed audibly, and the answering operation was performed using the connection cord (string) with the string method.

[0003]

In the conventional 119 reporting line response system, the number of lines connected to and accommodated in the emergency device is small unlike the exchange, so that the 119 reporting line can be used when a disaster occurs while using the emergency device. When there is congestion, there is a limit to the number of messages that can be answered simultaneously. Further, since all the 119 reporting lines are switched to the emergency device side and accommodated, there is a problem that all the 119 reporting lines become unresponsive when a failure occurs in the emergency device.

An object of the present invention is to provide a 119 information line response system which enables connection between the 119 information line and a general telephone.

[0005]

The 119 notification line response system of the present invention is a 119 notification line response system in a fire fighting communication command system, and a call path control circuit for controlling the response of the 119 notification line, and a caller who has recovered during communication. A call back circuit, a subscriber circuit for controlling a general telephone for receiving a notification, a switching circuit for switching the 119 reporting line to the general telephone side in an emergency such as a failure of the fire-fighting communication command system, and each of the circuits. A control circuit for controlling the fire fighting communication command system is provided to automatically switch the 119 reporting line in the event of an emergency such as a failure of the fire-fighting communication command system and control the response by the general telephone. Also, by dialing a predetermined number from the general telephone, the switching circuit is controlled to forcibly select all lines or only specific lines of the 119 reporting line and switch response control to the general telephone side.

[0006]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a 119 reporting line response showing an embodiment of the present invention, and FIG. 2 is a 119 reporting line trunk 4
It is a block diagram of. 119 The information line trunk 4 is 119
A call path control circuit 9 that is installed corresponding to each notification line and that controls the response of the 119 notification line, a switching circuit 12 that switches the call path in an emergency, and a call to call back the caller who has recovered to the destination during the call A return circuit 13, a subscriber circuit 11 for controlling a general telephone for receiving a notification, and each of these circuits (9,
11, 12, 13) and a control circuit 10 for controlling the same.

When the whistleblower 7 dials 119, 1
The 19-notification circuit 5 is controlled and the 119-notification line trunk 4 enters the incoming state. The call control circuit 9 of the 119 notification line trunk 4 detects the incoming call and notifies the control circuit 10 of the incoming call information (see FIG. 2). The control circuit 10 discriminates whether the command board 1 or the general telephone 8 is terminating, and the switching circuit 12
To control.

The control circuit 10 identifies this destination by the following method. The central processing unit 3 diagnoses the normality at regular intervals by the control circuit 10 of the 119 information line trunk 4 and predetermined information. When a failure occurs in the central processing unit 3, the control circuit 10 of the 119 information line trunk 4
Recognizes a failure of the central processing unit 3 (fire fighting communication command system) because it cannot receive information within a certain time.

When a fault is recognized in the 119 information line trunk 4, the incoming call information is sent to the central processing unit 3 once, but the response information to that is sent to the central processing unit 3.
Control circuit 10 switches the switching circuit 12 to the general telephone 8 side so as to control the incoming call.

When the central processing unit 3 is out of order, if there is an incoming call on the 119 information line trunk 4, the incoming call is sent to the general telephone 8 by the above-mentioned method, but the control circuit 10 controls the subscriber circuit 11 to send out a calling signal. Give instructions. As a result, a ringing tone is sent to the general telephone 8. When the notification receptionist responds by off-hooking the ordinary telephone 8, the subscriber circuit 11 detects this response and notifies the control circuit 10 of the response information.
The control circuit 10 controls the call path control circuit 9 so that the caller 7 and the call reception handler of the general telephone 8 are in a call state.
At this time, if the caller 7 recovers first, the call control circuit 9
Thus, the recovery is detected and the control circuit 10 is notified. In addition, the report receptionist can know the recovery of the reporter by the busy tone.

In this way, when the caller recovers in a half-way, and the report receptionist calls the caller again, a predetermined special number for calling back the caller is dialed from the general telephone 8. . This dial information is detected by the subscriber circuit 11 and notified to the control circuit 10. The control circuit 10 analyzes that it is dial call back information, and controls the call back circuit 13 to perform call back control until the caller 7 responds or the call reception handler recovers.
When the caller 7 responds, the call path control circuit 9 detects this response and notifies the control circuit 10 to end the call back control and return to the call state.

When the person who receives the notification receives the general telephone 8 on-hook and recovers, the subscriber circuit 11 detects this recovery (the control circuit 10 is notified and the communication path control circuit 9 and the switching circuit 12 are controlled to the recovery state). To end the call.

Further, when the general telephone 8 is controlled to forcibly switch the 119 reporting line to the general telephone 8, the general telephone 8 dials a predetermined number. This dial information is used by the subscriber circuit 1
It is recognized by the control circuit 10 via 1. Control circuit 10
Switches the switching circuit 12 and switches to the general telephone 8. The control circuit 10 controls the response control of the 119 notification line to the general telephone side until the forced switching is released.

The above-mentioned 119 information line trunk 4 shown in FIG.
Also, the case where each of the general telephones 8 is one has been described. However, when a plurality of 119 reporting trunks 4 and general telephones 8 are provided correspondingly, when the 119 reporting lines are forcibly switched to the general telephones, except for all line switching. Since it is also possible to switch only the 119 reporting line, any fire alarm communication command system side failure can be detected and automatically switched to the general telephone side.
When the reporting line is forcibly switched to the general telephone side, or when the fire-fighting communication command system is operating normally and the emergency call from the caller is congested, a part of the 119 reporting line is switched to the general telephone side to handle multiple notifications. It becomes possible for a person to respond to an emergency call.

[0015]

As described above, the present invention controls the call path control circuit for response-controlling the 119 notification line, the call back circuit for returning the caller who has been restored during communication, and the general telephone for receiving the notification. It is composed of a subscriber circuit, a switching circuit for switching the 119 notification line to the general telephone side in case of an emergency of the system, and a control circuit for controlling these circuits.
By setting up 19 reporting line trunks for each 119 reporting line, when a failure of the fire fighting communication command system is detected, all 119 reporting lines automatically switch to the general telephone side to respond to the emergency call of the caller. it can.

Further, by dialing from the general telephone, only an arbitrary 119 reporting line can be switched to the general telephone side. Therefore, when there are a lot of emergency calls from the caller and the response from the command console is congested, a part of the incoming call is generally received. By receiving an incoming call to the telephone, it is possible to respond simultaneously with the command board.

Furthermore, since all 119 reporting lines can be forcibly switched to the general telephone side, for example, maintenance and inspection of the fire-fighting communication command system can be facilitated.

Furthermore, since the 119 information trunk is connected to each 119 information line, even if a part of the 119 information trunk failure occurs, an emergency call from the caller can be dealt with by the command desk or ordinary telephone.
