Description

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

[Conventional technology]

Generally, an elevator car remote reporting device is equipped with an emergency switch and an intercom device inside the elevator car, and when the emergency switch is operated, the intercom device is activated and connected to a monitoring center via a telephone line. There are those that allow you to talk to the control unit at the center, and those that have a television camera installed inside the car and transmit the situation inside the car to a television receiver in a manager's room or the like.

In addition, as this type of device, for example, Utility Model Application No. 58-486
69, Japanese Utility Model Application Publication No. 178768/1987, and the like.

[Problem to be solved by the invention]

Conventional elevator car remote notification devices can only communicate with each other, making it difficult for the monitoring center to grasp the situation inside the car. Even if there is a cage, the information is normally transmitted from the same person in the building's manager's room or to a TV receiver installed on the floor. be. However, recently a device has been developed that transmits images lost by a TV camera via a telephone line, and if this is used, it is possible to transmit the situation inside the car to the monitoring center.
This method had the disadvantage of requiring a new telephone line, which was costly.

The present invention aims to eliminate this drawback, and its purpose is to provide a remote notification device for an elevator that can transmit images to a monitoring center without installing a new telephone line.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an intercom device and a television camera in an elevator car, and a switching device on the elevator car side that can switch and connect the same telephone line to a facility sensor, a television camera, and an intercom device. The monitoring center is provided with a command device for selectively switching the switching device.

[For production]

Since the elevator remote notification device according to the present invention is configured as described above, the switching device provided on the elevator car side is operated by a command from the monitoring center side, and the telephone line is switched between the equipment sensor, the TV camera side, and the intercom device side.・This allows the monitoring center to receive video, audio, and data from installed sensors over the same telephone line without having to install a new telephone line for the TV camera. .

〔Example〕

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

The drawing is a configuration diagram showing one embodiment of an elevator remote reporting device. Inside the elevator car 1, an intercom device 2 combined with an emergency switch and a television camera 3 are installed. The intercom device 2 was installed through a signal transmission path 5, and the television camera 3 was installed through a signal transmission path 5' in an elevator machine room (not shown) or the like. Terminal device 6
This terminal device 6 is provided with a switching device 7 and a control device 8. Further, the building equipment sensor 9 is connected to the terminal device 6. The terminal device 6 is connected to a monitoring center 11 via a telephone line exchange 10. The monitoring center 11 is equipped with a communication device 12 for communicating with the intercom device 2, a command device 13 for operating the switching device 7, a monitor device 14 for monitoring images from a television camera, and a monitoring device 15 for monitoring abnormalities in equipment sensors. It is equipped with a switching device 16 that switches in response to.

Now, when a passenger inside the elevator operates the emergency switch 4, this operation command is transmitted to the control device 8 via the signal transmission path 5 and the switching device 7. As a result, the control device 8 automatically dials and communicates with the command device 13 of the monitoring center 11 via the telephone line exchange 10, and the command device 13 recognizes that the call is a call and connects to the telephone set 12. As a result, the controller at the monitoring center 11 and passengers in the elevator can have a conversation using the communication device 12 and the intercom device 2.

At this time, when the controller wishes to check the situation inside the car on video, the controller operates an operation switch (not shown) provided in the command device 213. When this command device 13 is operated, it switches the switching device 16 to the monitor device 14 side, and a command is transmitted to the control device 8 via the exchange 10. This is recognized and the switching device 7 is switched to the signal transmission path of the television camera 3. Switch to 5'. As a result, the telephone line exchange IO interrupts the call and transmits a video signal,
This video signal is monitored by the monitor device 14 via the command device 13 and the switching device 16, so that the controller can visually judge the situation inside the car. In this way, communication can be carried out without having to install a new telephone line for the television camera.

After this determination, the conversation can be switched again by a command from the command device ff113. Here, the call interruption time is, for example, 5 to 6
A 4-meter video of the operation switch (not shown) installed in the control device 1°3 from the controller 1 in 2 seconds.
When the transmission of the signal is completed, the control device 8 instructs the switching device 7 to switch to the intercom device 2 side. Similarly, the command device 13 commands the switching device 16 to switch to the intercom device 12 side, and again connects the intercom device 2 and the intercom device 1.
2, passengers in the elevator car and the controller can have a conversation.

On the other hand, if an abnormality occurs in the building equipment during this period, the control device 8 recognizes this, switches the switching device 7 to the equipment sensor side, and informs the command device 13 via the switch IO, and the command device 13 indicates that there is an abnormality in the building equipment. Recognizing this, it switches the switching device 16 to the monitoring device 215 side, sends the building equipment abnormality data to the monitoring device 15, and reports by displaying or printing the building management number, building name, faulty equipment name, fault status, etc. Therefore, air traffic controllers can respond accordingly. After the building equipment abnormality data signal ends, the command device 13 of the monitoring center 11
The control device 8 is switched to the intercom device 2 side by the operation. Further, the command device 13 is also switched to the communication device 12 side, and the passengers in the elevator car and the control staff can once again have a conversation.

〔Effect of the invention〕

As explained above, the present invention allows video, audio, and building equipment abnormality to be communicated through the same telephone line, so communication can be performed without providing a new telephone line for the television camera.
