Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an elevator communication device, and in particular, to an elevator suitable for efficiently inspecting communication between an in-car intercom and a monitoring center. It relates to a communication device.

[Conventional technology]

In general, when it comes to elevator communication devices, for example, when a passenger is trapped in a car due to a malfunction in an elevator installed in a building, etc., if the passenger manually operates the call button on the in-car intercom, the The terminal device detects the activation of the above-mentioned operation button and automatically reports to the monitoring center via the telephone line, and as a result, the in-car intercom is connected to the monitoring center, so passengers in the car can be monitored. The system calls the air traffic controller at the center regarding the situation.

In the elevator communication device configured as described above, it is required that the communication function between the car internal communication device and the monitoring center is always normal. Normally, it is inspected once every month. For this reason, especially as the number of in-car intercoms installed increases, the number of calls processed by the monitoring center for checking the call function increases accordingly, which sometimes causes the problem that call requests are concentrated at the monitoring center. Ta.

In such a case, it becomes extremely difficult for the monitoring center to respond to abnormality reports, which is its primary job, so it is necessary to increase the number of response devices and controllers on the monitoring center side in order to respond to the concentrated call requests.

As a means of solving such problems, for example, the monitoring center is equipped with an abnormality response device that responds to abnormality reports and an inspection response device that responds to call inspection requests. Some devices are equipped with a call inspection switch that switches to inspection mode for talking to the device. In this typical elevator communication device, maintenance personnel operate the communication inspection switch to switch the terminal device to inspection mode.
A call is made between the in-car intercom and the above-mentioned inspection response device. After this call check, the call check switch is operated again to return the terminal device to its normal state. However, sometimes people forget to reset the call inspection switch to its normal state, and in such cases, when a call signal is output from the car's intercom, the abnormality report from the terminal device is sent to the inspection response device. There was a problem in that the abnormality was not transmitted, that is, the abnormality notification was not sent to the abnormality response device.

Therefore, an elevator communication device has been proposed in the past, as described in Japanese Patent Application No. 150391, which is provided with a non-return release device that automatically resets the communication inspection switch.

In this elevator communication device, after completing the call inspection report in the inspection mode, the mode setting status by the call inspection switch is detected, and if the mode has been switched to the inspection mode, the non-return release device automatically The call inspection switch is reset to return from inspection mode to normal monitoring mode.

[Problem to be solved by the invention]

By the way, in the above-mentioned conventional elevator communication device, the method of returning from the inspection mode to the normal monitoring mode is to automatically reset the communication inspection switch after the communication inspection report is finished using the non-return release device, or to have maintenance personnel There are only two options: manually return the call check switch. For this reason, before maintenance personnel set the inspection mode by operating the call inspection switch and perform call inspection work, it is necessary to perform work other than call inspection, such as repairing an elevator malfunction, or when performing call inspection work. If the elevator owner or other person requests an explanation during work and the work is interrupted, maintenance personnel must go to the location where the telephone inspection switch is installed each time in order to return from inspection mode to normal monitoring mode. There is a problem that it must be done.

In addition, after the call inspection work is completed, if the call inspection report is not completed normally due to a malfunction of the intercom in the car, a malfunction of the telephone line, or a malfunction of the inspection response device at the monitoring center,
As in the above case, in order to return from the inspection mode to the normal monitoring mode, maintenance personnel must go to the location where the call inspection switch is installed.

The present invention has been made in view of the actual situation in the prior art, and its purpose is to provide an elevator that can automatically return the terminal device to the normal monitoring mode without requiring a reset operation by maintenance personnel. The purpose of the present invention is to provide a communication device.

[Means to solve the problem]

To achieve this objective, the present invention provides a telephone set installed in a car and having a call button that outputs a calling signal;
A terminal device that has a mode switching means capable of switching from a normal monitoring mode to an inspection mode during an inspection call, and transmits either a monitoring call signal or an inspection call signal via a telephone line in response to the above-mentioned call signal. and a monitoring center having an abnormality response device that responds to the monitoring call signal, and an inspection response device that responds to the inspection call signal, wherein the terminal device is configured to switch from the monitoring mode to the inspection mode by the mode switching means. a timer that outputs an output signal after a predetermined time after switching to the mode; and a first reset that outputs a first reset command for returning to the monitoring mode to the mode switching means in accordance with the output of the output signal. command means; and second reset command means for outputting a second reset command for returning to the monitoring mode to the mode switching means in response to the output of the inspection call signal when the inspection mode is switched. This is the configuration I set up.

[For production]

Since the present invention is constructed as described above, when performing a call check, when the mode switching means of the terminal device switches to the check mode, the timer starts counting operation. If a predetermined period of time elapses without a calling signal being output from the intercom in the car in this state, the above-mentioned timer outputs an output signal. Then, in response to this output signal, the first reset command means outputs the first reset command to the mode switching means, so that the terminal device is switched to the normal monitoring mode by the mode switching means.

On the other hand, if a calling signal is output from the intercom in the car before the above-mentioned timer finishes counting, the terminal equipment sends an inspection call signal to the monitoring center via the telephone line in response to this calling signal. The monitoring center responds to the above-mentioned inspection call signal using an inspection response device. Then, in response to the output of the above inspection call signal, the second reset command means outputs a second reset command to the mode switching means, so that the terminal device is switched to the normal monitoring mode by this mode switching means. .

This allows the terminal device to automatically return to the normal monitoring mode without requiring maintenance personnel to perform a reset operation.
