Description

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

[Conventional technology]

FIG. 2 is a block diagram of a conventional elevator communication device. In FIG. 2, reference numeral 1 denotes a communication device in the passenger car, which is connected to a starting switch 2 and a handset 3, and is connected together with a plurality of equipment 4 to a control device 10 of a building terminal device. The building terminal device T includes a control device 10 that manually controls signals from the in-car communication device l and equipment 4, and an abnormal signal control device l4 that creates alarm data. It is equipped with an alarm device l6 that performs automatic dialing and the like. A monitoring center C is connected to the building terminal device T via a telephone line D, and is comprised of an abnormality response device 20 that responds to alarms and the like.

Conventional monitoring center C and communication device 1 in the elevator car
The call check between the two was working as follows. First, when the inspector presses the start switch 2 of the in-car communication device 1, this signal is sent to the control device 10 in the building terminal device T. When the control device 10 recognizes the call request, it sends this signal to the abnormal signal control device 14, which creates the telephone number of the destination, the content of the signal, etc., and the alarm device 16 receives this signal. A notification is sent to the monitoring center C via the telephone line D. On the other hand, the abnormality response device 20 of the monitoring center C recognizes that the call request is from the building terminal device T based on the received information, and calls the handset 3 of the in-car communication device L via the telephone line D. It enables communication with the response device 20. In this way, by making a call between the inspector on the in-car communication device 1 side and the operator at the monitoring center C{jlj, and notifying the operator of the call inspection, the building terminal device T
I was checking to see if the communication function between C and center equipment C was normal.

[Problem to be solved by the invention]

To check the communication function between the in-car communication device and the monitoring center,
Due to its nature, it is normally carried out periodically, for example, once a month. Therefore, as the number of building terminal devices increases, the number of call inspections processed by the monitoring center increases and may be concentrated at one time. In this case, there was a problem in that the monitoring center had to increase the number of response devices and operators in order to cope with this. Also,
When the call inspections are concentrated all at once, there is a problem in that the monitoring center is unable to respond to abnormality notifications from building terminal devices, which is the original function of the monitoring center.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator communication device that suppresses the need to increase the number of specialized operators on the monitoring center side and does not impede response when an abnormality is reported.

[Means to solve the problem]

In order to achieve the above object, the present invention connects an in-car communication device and a terminal device that monitors equipment in a building, and when the elevator communication device is activated, a communication device installed in the terminal device is connected. The automatic dialing device connected to the abnormality response device of the monitoring center via a telephone line to enable a call can be sent to the monitoring center to respond when the in-car communication device is inspected. On the other hand, the terminal device includes a call inspection switch that is operated by an inspector when inspecting the in-car communication device, and a call inspection switch that operates the in-car communication device when the call inspection switch is operated. A call destination switching device switches and connects the call destination to the inspection response device, and after the call inspection is completed, detects that the call inspection switch has not been switched to the original normal mode and automatically switches the call inspection switch to the normal mode. The present invention is equipped with a non-return release device.

(Function) When the inspector operates the call inspection switch, the terminal device recognizes that the elevator communication device is being inspected, and uses the alarm destination switching device to issue an alert to the inspection response device instead of the normal response device. Then, after the call ends, the call inspection switch is returned to the original normal mode to complete the call inspection.At this time, even if you forget to return the call inspection switch to the original normal mode, the call inspection switch will automatically return to the original normal mode. Operate the alert destination switching device to switch to the normal response device.

This prevents the need to increase the number of response devices and operators, and also prevents the inspection mode from continuing even after the end of the call inspection, resulting in a situation where the abnormality response device cannot be notified even if an abnormality occurs in equipment. I can do it.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. 1st
FIG. 1 is a block diagram of an electronic communication device according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes an in-car communication device for communicating with the monitoring center C side, which is composed of a communication start switch 2 and a handset 3. It is connected to the control device 10. T is a building terminal device installed in the manager's room of each building, and inputs the call request signal from the in-car communication device 1, the abnormality signal from the equipment 4, and the signal from the call inspection switch 11. and a control device 10 that creates a control signal, an alert destination switching device 13 that switches alert destinations in response to the control signal, and an abnormality that is selected by the alert destination switching device 13 and creates alert data. The signal generation device 14, the inspection signal generation device 15, the alarm device 16 that performs automatic dialing etc. upon receiving the abnormal signal and inspection signal, and the call inspection switch 1l set to the normal mode after the call inspection is completed. A non-return release device 12 detects when the alarm is not returned and automatically switches the alarm destination switching device 13 to the abnormal signal control device 14 side. C is a monitoring center, among the alarms sent from the building terminal device T via the telephone line D, data related to abnormal alarms is sent to the abnormality response device 20, and data related to call inspection is sent to the inspection response device 21. respond.

Next, the operation of one embodiment of the present invention will be explained.

When the inspector operates the call inspection switch 11 to set the inspection mode, the signal is input to the control device 10, and the control device W1
0 receives this check signal and recognizes that it is a call check. Next, when the inspector operates the start switch 2 of the in-car communication device 1, it is manually input to the control device 10 as a call request signal, and sent to the alert destination switching device 13 as a control signal together with the inspection signal, and the The release device 12 is notified that a call inspection request has occurred. Based on this control signal, the alert destination switching device 13 recognizes that it is a call inspection alert, selects the inspection signal generating device 15, and connects with it. The connected inspection signal generation device 15 sends data such as the telephone number of the inspection response device 2l of the monitoring center C and the identification number of the building terminal device T requesting a call to the alarm device 16, and the alarm device 16 receives the data. Based on the received data, the inspection response device 2l is dialed and an alarm is issued.

On the other hand, when the inspection response device 2l in the monitoring center C receives an alarm from the building terminal device T via the telephone line D, it responds with a previously stored voice message such as "This is the monitoring center.

Please start the inspection. " to prompt the start of inspection.

The inspector who hears this voice through the handset 3 speaks predetermined information into the handset 3, such as the name of the building, the identification number of the building terminal device T, and the name of the inspector.

This voice is transmitted for a predetermined time by the inspection response device 2l.
For example, it is recorded for 15 seconds, and after 15 seconds, it is reproduced and output for the inspector to listen to via the handset 3.

The inspector listens to this voice, confirms that the voice he or she has uttered has been returned, and concludes the inspection. At this time, if the playback audio cannot be confirmed and the call is poor, after the line is disconnected,
The call inspection switch 1l is returned to the original normal mode, the start switch 2 is operated again, a notification is issued to the abnormality response device 20, and the inspector takes action by talking to the operator and confirming the call status.

After reproducing the recorded voice, the inspection response device 2l issues a line disconnection command to the building terminal device T, and also disconnects the line itself.

After checking the call status, the inspector returns the call inspection switch 11 to the original normal mode to complete the call inspection. However, if the inspector forgets to return the call inspection switch 11 to the original normal mode at this time, this may occur. Thereafter, even if an abnormality occurs in the equipment 4, for example, the inspection response device 21 is notified, and the abnormality response device 20, which is handled by the operator, has no abnormality data, resulting in a situation where the abnormality cannot be dealt with. In order to prevent this, if you forget to return the call inspection switch 11 to the original normal mode, the non-return release device i1i12 that monitors the call inspection switch automatically operates the alarm destination switching device 13 and It is connected to the signal generation device 14 so that an alarm can be sent to the abnormality response device 20.

In this way, in this embodiment, when the elevator communication device is inspected, the inspection response device 2l takes care of the inspection, so it is possible to prevent an increase in the number of operators. Furthermore, since the call inspection recognition signal is generated by the operator's operation of the call inspection switch 1l, there is a possibility that the operator may forget to return the call inspection switch 1l. By providing this, it is possible to prevent a situation in which the inspection mode continues even after the end of the call inspection and the error response device 20 cannot be notified even if an error occurs.

〔Effect of the invention〕

In the present invention, since the inspection response device takes care of the call inspection of the elevator communication device, it is possible to suppress the need for an additional operator.Furthermore, even if you forget to return the communication inspection switch at the end of the inspection of the elevator communication device, the inspection response device can respond automatically. Since the system is configured to return to the state before the inspection, it is possible to reliably deal with abnormalities that occur after the inspection is completed.
