Abstract

PURPOSE:To make simultaneous response possible and to enable all 119 communication lines to be respond to the occurrence of failure in a 119 communication line converter by sending a call to an ordinary telephone set via the 119 communication line converter in case when the system side fails. CONSTITUTION:When a reporter 4 dials number 119, a 119 communication circuit 9 is controlled and is set in a call state. Speaking line control circuit 5 of the 119 communication line converter 2 detects that a report has reached, and informs a control circuit 6 of arrival information. The control circuit 6 controls a subscriber circuit 7 to direct the circuit 7 to send a call signal, while the reporter 4 and a report receiving handler for ordinary telephone set 1 are set into a talking state. When the report receiving handler talks with the reporter 4 again after reporter 4 recovers earlier, a particular number is dialed from the ordinary telephone set 1 for calling back a predetermined reporter. The control circuit 6 analyses that dial is call back information, and controls a callback circuit 8 to carry out callback control until the reporter 4 responds or the report receiving handler is recovered.

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

0002

[Prior Art] In a conventional fire communication command system,
Since it is impossible to respond to the 119 call line using a regular telephone, we have an emergency device in case of an emergency on the system side such as a failure of the command system, and in case of an emergency, all 119 call lines are switched from the system side to the emergency device. Incoming calls were displayed visually and audibly for each line, and responses were operated using a connection cord using a tethered system.

0003

[Problem to be Solved by the Invention] With this conventional 119 call line response method, the number of lines that can be handled simultaneously by the emergency device is small compared to a switchboard, so when using the emergency device, the 119 call line cannot be used in the event of a disaster, etc. In times of congestion, there is a limit to the number of calls that can be answered at the same time. Furthermore, since all 119 reporting lines are switched to and accommodated by emergency equipment, there is a problem in that if a failure occurs in the emergency equipment, all 119 reporting lines become unresponsive.

[0004] An object of the present invention is to provide a 119 call line response system that enables connection between the 119 call line and a general telephone set.

[0005]

[Means for Solving the Problems] The 119 call line response system of the present invention provides a communication route control circuit for controlling the response of the 119 call line, and a callback circuit for calling back a caller whose communication has been restored, in a fire department communication command system. , a subscriber circuit that controls a general telephone set for receiving reports, and a control circuit that controls each of the circuits, and notifies the control circuit of incoming call information from the informer detected by the call path control circuit. This control circuit controls the subscriber circuit to make the incoming call arrive at the general telephone set for receiving the report and enter a talking state, and also to resume communication with the caller who was restored during communication. 1. The subscriber circuit detects the dial information sent from the general telephone for reception, and the control circuit instructs the call-back circuit to call back the caller based on this detection information.
A 119 reporting line conversion device is provided corresponding to the 119 reporting line.

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

FIG. 1 is a block diagram of a 119 notification line response showing an embodiment of the present invention. The 119 reporting line conversion device 2 is installed corresponding to each 119 reporting line, and includes a communication path control circuit 5 that controls the response of the 119 reporting line, a callback circuit 8 that calls back the caller who was restored earlier, and a reporting reception circuit. A subscriber circuit 7 that controls a general telephone set for use in
7 and 8).

[0008] When caller 4 dials 119, 1
The 19 notification circuit 9 is controlled and enters the incoming call state. The communication path control circuit 5 of the 119 reporting line conversion device 2 detects the incoming call and notifies the control circuit 6 of the incoming call information. The control circuit 6 controls the subscriber circuit 7 and instructs it to send out a paging signal. As a result, a ringing tone is sent to the general telephone set 1. When the report reception operator takes the general telephone 1 off-hook and responds, the subscriber circuit 7 detects this response and notifies the control circuit 6 of the response information. The control circuit 6 controls the call path control circuit 5 to be in a response state, and the caller 4 and the report reception operator of the general telephone 1 are in a talking state.

[0009] At this time, if the informant 4 recovers first,
The communication path control circuit 5 detects the recovery and notifies the control circuit 6. In addition, the report reception handler can be informed by an audible (busy tone) that the caller has recovered.

[0010] Here, when the report reception operator wants to talk to the informer 4 again, he dials a predetermined special number for calling back the informer from the general telephone set 1. 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 callback information, controls the callback circuit 8, and performs callback control until the caller 4 responds or the callback operator recovers. When the caller 4 responds, the call path control circuit 5 detects this response and notifies the control circuit 6, thereby ending the callback control and returning to the call state.

[0011] When the report reception handler on-hooks the general telephone 1 and restores the telephone, the subscriber circuit 7 detects this restoration, notifies the control circuit 6, controls the call path control circuit 5 to the restored state, and starts the call. finish.

[0012] The 119 call line conversion device 2 is installed corresponding to each 119 call line, so if there is a congestion of calls during normal operation, some of the calls are switched and the calls are sent to the general phone for the call handler. It is also possible to do so.

[0013]

Effects of the Invention As explained above, the present invention provides a call path control circuit for responding to and controlling a 119 reporting line, a call-back circuit, a subscriber circuit for controlling a general telephone set, and a control circuit for controlling each of the above-mentioned circuits. A 119 call line conversion device having
By installing individual 119 reporting lines, 119
Since the response control of the reporting line is converted to the control method of regular telephones, even in the event of a system failure or when the 119 reporting line is congested due to a disaster, some of the incoming calls will still be received by the regular telephone via the 119 reporting line converter. This enables simultaneous responses.

Furthermore, since a 119 call line converter is connected to each 119 call line, even if a failure occurs in the 119 call line converter, all 119 call lines will not become unresponsive.
