Thus, when an abnormality of the equipment occurs during the call inspection, the abnormality of the equipment can be immediately notified to the monitoring center.

〔Example〕

Hereinafter, an embodiment of an elevator communication apparatus according to the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of an elevator communication apparatus according to the present invention.

As shown in FIG. 1, an elevator communication device according to the present invention is a telephone having a start switch 2 and a handset 3 which are installed in a car in a building 1 where an elevator is installed and operated during a call. And a terminal device T connected to the telephone 4 and the equipment 5 in the same building, and issuing a notification via a telephone line D to a monitoring center C provided with an abnormal response device 6 and an inspection automatic response device 7. The terminal device T includes a report destination switching device 8 for switching the report destination,
An abnormality which is connected to the talker 4 and the facility equipment 5 and has a manually operated call check switch 9 and a control device 10 provided with the above-mentioned notification destination switching device 8 for generating notification data. A signal generation device 11 and an inspection signal generation device 12 and an alarm device 13 connected to the abnormal signal generation device 11 and the inspection signal generation device 12 and performing automatic dialing to the monitoring center C via the telephone line D. Have.

Then, when an abnormality occurs in the equipment 5 at the time of the call check of the intercom 4, the notification destination from the terminal device T is switched from the check automatic response device 7 side to the abnormality response device 6 side to perform the abnormality report. Alarm factor identification device that outputs a notification command
14 is provided in the terminal device T.

In this embodiment, when the caller checks the communication device, the checker operates the call check switch 9 to enter the check mode, a check signal is input to the control device 10, and the control device 10
Receives this check signal and recognizes that it is a call check. Next, the inspector starts the switch 2 of the telephone 4 in the car.
Is operated, a call request signal is output to the control device 10, and the control device 10 outputs the check signal and the call request signal together to the alarm cause identification device 14. The alerting factor identification device 14 checks the presence or absence of an abnormal signal from the equipment 5 and issues a call inspection signal if there is no abnormal signal, and issues an abnormal signal ignoring the call inspection request if there is an abnormal signal. Output to the destination switching device 8. The notification destination switching device 8 discriminates the input signal, selects and connects the inspection signal generation device 12 when the signal is a call inspection signal, and selects the abnormal signal generation device 11 when the signal is an abnormal signal. And connect. The inspection signal creation device 12 stores data such as the telephone number of the inspection automatic response device 7 of the monitoring center C and the identification number of the terminal device T requesting a call, and the abnormal signal generation device 14 stores the telephone number of the abnormality response device 6 of the monitoring center C. And the data such as the identification number of the terminal device T requesting the call is output to the alarm device 13, and the alarm device 13 dials the inspection automatic response device 7 or the abnormal response device 6 based on the input data.

On the other hand, when the abnormality response device 6 in the monitoring center C receives the abnormality signal from the terminal device T via the telephone line D, the abnormality response device 6 notifies the operator of the information on the occurrence of the abnormality and prompts the operator to take prompt action. In addition, the inspection automatic response device 7 in the monitoring center C
When a call inspection signal from the terminal device T is received via the telephone line D, an inspection start signal, for example, a voice signal “This is a monitoring center. Start inspection” is transmitted via the telephone line D and the terminal device T. To the handset 3 of the handset 4 to urge the inspector to start the check. When the output of the voice is completed, the mode enters a mode in which the voice of the inspector is recorded. Utter. This voice is recorded by the inspection automatic response device 7 in the recording mode for a predetermined time, for example, 10 seconds, and then the recorded voice is reproduced, and the voice of the telephone 4 is transmitted through the telephone line D and the terminal device T. The message is transmitted to the handset 3 to be heard by the inspector. After that, the inspection automatic response device 7 outputs an inspection end signal, for example, a voice signal of "I'm very nervous. This ends the call inspection." Listen to the end message and confirm that it is working properly. On the other hand, after outputting the inspection end signal, the inspection automatic response device 7 issues a line disconnection command to the terminal device T, and disconnects the line itself. Then, the inspector returns the call inspection switch 9 to the original normal mode and ends the call inspection. At this time, the recording / reproducing sound or the voice message cannot be confirmed. If the communication is poor, after disconnecting the line, the call inspection switch 9 is returned to the normal mode, and the start switch 2 is operated again to operate the abnormal response device 6. , And the inspector talks with the operator to check the call status and take other measures.

Further, if an abnormality occurs in the equipment 5 during the above-described call check, the abnormality signal output from the equipment 5 is input to the alarm factor identification device 14 via the control device 10. When the alerting factor identification device 14 detects the above-mentioned abnormality, it instructs the alerting device 13 to disconnect the line to stop the call check, and automatically notifies the alerting destination switching device 8 of the alerting destination. The switching notification command is output to switch from the device 7 to the abnormality response device 6. In response to this, the notification destination switching device 8 switches the notification destination, and issues an abnormality signal to the abnormality response device 6 of the monitoring center C in the same manner as described above.

In the present embodiment configured as described above, when an abnormality of the equipment 5 occurs during the call inspection, the abnormality of the equipment 5 can be immediately notified to the monitoring center C.

In this embodiment, the example in which the inspection automatic response device 7 is provided in the monitoring center C is shown, but instead of being provided in the monitoring center C, it may be provided at another place outside the monitoring center C. . Further, the example in which the alarm factor identification device 14 is provided in the terminal device T has been described.
The same effect can be obtained even if the command is issued from the monitoring center C to switch the report destination. Further, since the call inspection switch 9 may be forgotten to return to the normal mode at the end of the work, a function of preventing forgetting to return may be provided by using a switch that does not hold the state.
