Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In a conventional fire fighting communication command system,
Since it is impossible for the general telephone to respond to the 119 notification line, the system has an emergency device in case of an emergency in the system such as a failure in the command system. Incoming calls were displayed visually or audibly for each line, and response operations were performed using a connection cord in a cordless manner.

[0003]

In the conventional 119 notification line response method, the number of lines that can be handled simultaneously by the emergency device is smaller than that of the exchange, so that when the emergency device is used, the 119 notification line is used in the event of a disaster or the like. When congestion occurs, there is a limit to the number of messages that can be answered at the same time. In addition, since all the 119 notification lines are switched to the emergency device and accommodated, there is a problem that if a failure occurs in the emergency device, all 119 notification lines cannot respond.

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

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a 119 notification line response according to an embodiment of the present invention. 119 report line conversion device 2
Is installed in correspondence with each of the 119 notification lines, and controls a communication path control circuit 5 for controlling the response of the 119 notification lines, a call-back circuit 8 for calling back a previously notified caller, and a general telephone for receiving a notification. And a control circuit 6 for controlling these circuits (5, 7, 8).

When caller 4 dials 119, 1
The 19 notification circuit 9 is controlled to enter an incoming call state. The communication path control circuit 5 of the 119 notification line conversion device 2 detects that there is an incoming call, and notifies the control circuit 6 of the incoming call information. The control circuit 6 controls the subscriber circuit 7 to instruct transmission of a call signal. As a result, a ringing tone is transmitted to the general telephone 1. When the report reception operator responds by off-hooking the general telephone 1, the subscriber circuit 7 detects this response and notifies the control circuit 6 of the response information. The control circuit 6 controls the communication path control circuit 5 to be in a response state, and the caller 4 and the call reception operator of the general telephone 1 are in a call state.

At this time, if the reporter 4 recovers first,
The recovery is detected by the communication path control circuit 5 and notified to the control circuit 6. Also, the report reception operator can know the recovery of the reporter by audible (busy tone).

[0010] Here, when calling again with the reporter 4, the report reception operator dials a special number for returning the reporter from the general telephone 1 in advance. This dial information is detected by the subscriber circuit 7 and notified to the control circuit 6. The control circuit 6 analyzes that the dial is the call back information, controls the call back circuit 8, and performs the call back control until the caller 4 responds or the call receiving operator recovers. When the caller 4 responds, the call path control circuit 5 detects this response and notifies the control circuit 6 to terminate the call back control and return to the call state.

When the report reception operator recovers by hooking the ordinary telephone 1 on the hook, the recovery is detected by the subscriber's circuit 7 and is notified to the control circuit 6, and the communication path control circuit 5 is controlled to the recovery state to perform the telephone conversation. finish.

Since the 119 report line conversion device 2 is installed corresponding to each of the 119 report lines, when a report is congested during a normal operation, a part of the report is switched to be received by the general telephone for the report handler. It is also possible.

[0013]

As described above, the present invention provides a communication path control circuit for controlling the response of the 119 notification line, a call back circuit, a subscriber circuit for controlling a general telephone, and a control circuit for controlling each of the circuits. 119 reporting line conversion device having
The 119 notification line is installed corresponding to each
Since the response control of the notification line is converted to the control method of a general telephone, a part of the incoming call is received by the general telephone via the 119 notification line converter even when the 119 notification line becomes congested due to a disaster or the like in the event of a system failure. By doing so, simultaneous response is possible.

Further, since the 119 notification line converter is connected for each of the 119 notification lines, even if a failure occurs in the 119 notification line converter, all 119 notification lines do not become unresponsive.
