Accordingly, abnormality is generated in the elevator, when the starting switch 2 is operated, this time an audible signal device 8 is actuated, calling a professional controller in a supervisory center 10, and the abnormality is processed by a talk processor 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator communication device configured by connecting a communication device in an elevator car and a communication device in a monitoring center via a telephone line.

[Prior Art] Generally, an elevator car is provided with a reporting device, usually an interphone, for reporting an abnormal state that has occurred to the outside. This reporting device connects to the manager's office in the same building, allowing the manager to respond immediately if any abnormalities occur.

However, since we do not know when an abnormality will occur, a manager must be on standby 24/7. For this reason, recently, elevator maintenance companies have set up monitoring centers to manage elevators, and elevators and communication devices that connect the monitoring center and the elevator cars via electric 6FJ lines have been proposed, and some of them have been put into practical use.

By the way, this elevator communication device is required to undergo periodic inspections to ensure that communication can be carried out in the event of an abnormality, and this inspection was carried out as follows.

First, maintenance personnel go to the building where the elevator is installed.
Using a public phone, etc., contact the monitoring center to inform them that the elevator communication device will be inspected now. As a result, the monitoring center side takes an inspection response mode from a normal emergency response mode. After that, the maintenance staff operated the emergency button inside the car, connected the communication device at the monitoring center and the communication device inside the car via a telephone line, and checked the communication function by talking between the two. Conversely, if the monitoring center is called without contacting the monitoring center, everything will be handled by the emergency response system. Here, the emergency response system means to urgently contact a predetermined contact point and dispatch base in the event of an abnormality in the elevator.On the other hand, the inspection response system is to
There were no calls to the dispatch base during the inspection. Incidentally, such an elevator communication device is disclosed in Japanese Patent Application Laid-Open No. 61-1
It is introduced in JP-A No. 69066 and Japanese Patent Application Laid-Open No. 62-41175.

[Problems to be Solved by the Invention] Conventional elevator communication devices have the above-described configuration, so as the number of elevator cars increases and the number of elevator communication devices increases, the frequency of a series of call inspections processed at the monitoring center increases. , - I will concentrate at times. Therefore, in order to cope with this, the monitoring center has to increase the number of processing devices and response control equipment, and it is not possible to adequately respond to the abnormality alarm signal from the elevator communication device, which is the original function of the monitoring center. It's gone.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator communication device that allows easy inspection of a monitoring center without increasing the number of processing devices and control equipment.

Means for Solving the Problems] In order to achieve the above object, the present invention provides a communication device for maintenance personnel that is different from the communication device in the monitoring center, and a communication device for communication inside the elevator car that is operated by the maintenance personnel. The device is characterized in that it is provided with a switch for switching the call destination of the device to the maintenance shell communication device described in Section 2.

[Function] Since the elevator communication device according to the present invention has the above-described configuration, when a maintenance worker switches the switch Hg during inspection, the communication device in the car is switched and connected to the newly installed communication device for maintenance personnel. The elevator communication system can be inspected by talking with maintenance personnel who are not experts in control.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

A terminal T□ installed in a building in which an elevator to be monitored is installed and a telephone device 12 of a monitoring center 10 are connected via a telephone line K.

Inside the terminal T1, there is a control device 5 that detects a call from an intercom 1 provided in the car and controls a switching device 6;
An alarm device 8 connected to a terminal a of the switch 6 and an alarm device 9 connected to a terminal A of the switch 6 are provided. The intercom 1 is a communication device in the passenger car, and has a starting switch 2, a transmitter 3, and a receiver 4. Also, terminal T
i has a switch 7 operated by maintenance personnel, and when this switch 7 is closed and conditions are met, the control device W
5 operates to switch the switch 6 to the terminal a side, and when the switch 7 returns to the normal state, the switch 6 is switched to the terminal a side. Although this switch 7 may be newly installed, a normal maintenance/inspection switch can be used. The number of such terminals T1 to T0 corresponds to the number of installed elevators.

A distribution center 20 separate from the monitoring center 10 is provided with a maintenance worker communication device 21 connected to a telephone line K, and this maintenance worker communication device 21 is automatically dialed by the alarm bag M9. It is connected to an intercom 1, which is a communication device inside the car.

On the other hand, the communication device 12 of the monitoring center 10 is automatically dialed by the alarm device 8 and connected to the intercom 1, which is a communication device in the car.

Now, when the maintenance worker operates the switch 7 to inspect the communication device in the car, the terminal T□ detects that the innovator is being inspected. Next, maintenance personnel will turn on the start switch 2.
When the condition is satisfied by the operation of both switches 2 and 7, the control device 5 switches the switch 6 to the terminal side, activates the alarm device 9, and connects the communication device for maintenance personnel at the distribution center 2o. Automatically dials 21. Therefore, the maintenance personnel at the distribution center 20 can have a conversation with the maintenance personnel inside the car, and through this conversation they can inspect the intercom, which is the communication device of the car. Since the maintenance personnel at the distributed center 20 are not the control tools for the experts at the monitoring center 10, the number of control tools will not be increased.

Once this inspection is complete, the maintenance personnel inside the car should turn switch 7.
By returning the start switch 2 to its original state, the switch 6 is switched to the terminal a side. Therefore, when an abnormality occurs in the elevator and the start switch 2 is operated, the alarm device 8 is activated to call the control equipment in the monitoring center 10, and the call processing device 11 processes the abnormality notification. .

In the above-described embodiment, the switch 7 is configured with an existing maintenance/inspection switch, so the operation signals of the start switch 2 and the switch 7 are combined to switch the switch 6 to the terminal side. If this is a dedicated switch for inspection, the switch r9 may be switched to the terminal side using only this signal. Further, in the above embodiment, the distributed center 20 is installed at a different location from the monitoring center 10, but the same result can be obtained even if the monitoring center 10 is provided with a communication device 21 for maintenance personnel, which is not a control device, and which is answered by a maintenance personnel. effect can be obtained.

[Effects of the Invention] As explained above, the present invention provides a communication device for maintenance personnel that is different from the communication device in the monitoring center to which the control equipment responds, and uses the communication device for maintenance personnel to inspect the communication device in the passenger compartment. Since inspections are carried out through the inspection system, inspections can be carried out without increasing the number of specialist control equipment or processing equipment.
