Abstract

PURPOSE:To make telephone conversation performable to a respondent not a professional control engineer by a selector-connecting means, selecting a communicator to a checking responder from an abnormal talking audible processor for connection at the time of checking this communicator, in the side of an elevator cage. CONSTITUTION:When a maintainer operates a selector-connecting means A at time of checking a communicator, a communicator 1 in a cage is selected to a checking responder 11 from an abnormal talking audible processor 10 installed in a center unit C. In consequence, a response out of this checking responder 11 is merely to inform the presence and magnitude of a maintainer's voice, so that a respondent is not necessarily a professional control engineer, thus an increase of the personnel for the control engineers is restrainable.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator car communication device.

In particular, the present invention relates to an elevator car communication device connected to a center device via a telephone line.

[Conventional technology]

Generally, an elevator car is equipped with a reporting device, usually called an interphone, in order to report the abnormal state to the outside when an abnormality occurs in the elevator car. This reporting device usually leads to the manager's office in the same building.
The administrator was responsible for responding if any abnormality occurred. However, since we do not know when an abnormal situation will occur, managers and personnel must be on standby all day long.

In order to solve this problem, elevator maintenance companies have recently installed a center device to manage the elevators, and installed an abnormal call alarm processing device in this center device to communicate with the reporting device in the elevator car via a telephone line. Some of these have been proposed and some have been put into practical use. As a result, there is no need to have a manager on standby for each building terminal that has an elevator, and it has become possible to centrally manage pressure from the central device.

Such communication devices are required to be periodically inspected to ensure that calls can be made in the event of an abnormality. In this inspection method, when a maintenance worker operates the emergency button inside the passenger car, the dial is automatically dialed and a call is made to the abnormal call alarm processing device of the center device via the telephone line. That is,
The control staff at the center responded to the notification device in the passenger car from the abnormal call notification processing device in the center equipment, and had a conversation with the maintenance personnel. Note that the above-mentioned call inspection is usually carried out periodically and within a set time, about once or twice a month.

[Problem to be solved by the invention]

Since the conventional elevator car communication devices are constructed as described above, as the number of such communication devices increases, the frequency of call inspections to be processed by the center device increases, and the number of calls is concentrated at -100 minutes. In this case, the center equipment side has to increase the number of controllers who can handle each communication device in order to cope with this, and even if an abnormality report is received from the elevator, which is the original function of the center equipment, during inspection, It becomes impossible to process it.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator in-car communication device that allows easy inspection without increasing the number of specialized controllers on the center device side.

[Means to solve the problem]

In order to solve the above object, the present invention provides an inspection response device in the center device, and when inspecting the elevator car side pressure and notification device, the notification device is switched and connected from the abnormal call alarm processing device to the inspection response device. The present invention is characterized in that it is provided with switching connection means for performing the following.

[For production]

Since the elevator car communication device according to the present invention is configured as described above, when a maintenance worker operates the switching connection means during inspection, the in-car notification device is connected to the abnormal call alarm processing device provided in the center device. to the inspection response device. The response from the inspection response device is simply to notify the presence or absence of the maintenance personnel's voice and the level of the voice, so a specialized air traffic controller can be used as the responder, and it is possible to suppress the need for an increase in the number of air traffic control personnel. In addition, if specialized air traffic control personnel were to respond to maintenance personnel's inspections as in the past, this would interfere with abnormality reporting via other terminals.
This problem can be solved by separating the abnormal call reporting processing device and the inspection response device in the center device where air traffic controllers are on standby.

〔Example〕

An embodiment according to the present invention will be described below with reference to FIG.

Building terminals T, -Tn, which collect information from various equipment such as elevators, are connected to a center device C in the management department via telephone lines. Building terminal T.

has a switching connection means A, which includes a switching device 9 that switches between the abnormal call device 6 and the inspection call alarm device 7, and a control device 5 that controls this switching device 9 by a maintenance switch 8.
It consists of. A notification device 1 provided in an elevator car, which is one of the equipment, is connected to the control device 5.

The reporting device 1 includes a start switch 2, a transmitter 3, and a receiver 4.
is provided. And such a device is another building terminal T. It is also installed in In addition, the center device C has
An inspection response device 11 that is separate from the abnormal call alert processing device 10 is provided, and an inspection call alert device 12 that automatically responds at the time of inspection can also be provided.

In the case of an elevator inspection, when a maintenance worker operates the maintenance switch 8, the building terminal T detects that the elevator is inspected. Next, the maintenance worker operates the start switch 2 of the interphone, which is the reporting device 1 in the elevator car. As a result, the building terminal T.

The switching connection means A is actuated by the control device 5 within.

In other words, the control device 5 switches the switch 9 from terminal a to terminal A and connects it! IC1 The inspection call issuing device 7 activated by this switching automatically dials, and the notification device 1 is connected to the inspection response device 11 of the center device C. Therefore, maintenance personnel on the elevator side
The notification device 1 can be inspected by listening to the voice from the notification device 1 and checking the communication status.

On the other hand, if an abnormality occurs in the elevator at another building terminal Tn while the above-mentioned inspection is being carried out at the building terminal T, the passenger in that car operates the start switch 2 of the notification device 1, The abnormal call device 6 automatically dials through the switch 9 connected to the terminal a, and the abnormal call alarm processing device 10 allows the abnormal call device 6 to make a call to a controller who is waiting for the abnormal call.

During this time, the building terminal T is conducting an inspection with the center device C via the inspection response device 11 without any trouble.

In addition, the inspection automatic response device 1 in the center device C described above
2 has a built-in tape recorder, for example, and automatically starts recording operation when an inspection report is issued from the building terminal T.
The maintenance worker's voice from the transmitter 3 is set to be recorded for about 10 seconds. Thereafter, rewinding and reproduction are automatically performed, and maintenance personnel can perform inspection by opening the reproduced voice on the receiver 4. This makes it possible to inspect the 5-communication device without the need for specialized air traffic control personnel or even other responders.

〔Effect of the invention〕

As explained above, the present invention provides an inspection response device in the center device, and on the other hand, when inspecting the 5 notification device on the elevator side, this notification device is transferred from the abnormal call alarm processing device to the inspection response device. Since a switching connection means is provided, when the communication device is inspected, the switching connection means automatically connects to the inspection response device in the center equipment, making it impossible to communicate with responders who are not professional air traffic controllers. can do. In addition, at this time, specialized air traffic controllers who are on standby to report an abnormality can connect to the reporting device via another terminal using the abnormal call notification processing device, so there is no need to increase the number of air traffic controllers. In addition, it is possible to clearly respond to abnormality reports.
