Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator remote monitoring device for confirming the contents of a failure by checking the images before and after the failure together with the details of the failure when the failure occurs in the elevator, and recovering the failure early. About.

[0002]

2. Description of the Related Art Conventionally, an elevator remote monitoring system using a monitoring camera, for example, as shown in JP-A-9-194156, when a failure occurs in an elevator, a monitoring camera installed in the elevator is operated by a monitoring center staff member. The details of the failure were displayed at a remote monitoring center to identify the nature of the failure.

[0003]

However, in the conventional remote monitoring device, since the failure content is confirmed by an image after being displayed by the operation of the operator after the failure occurs, the failure is temporarily generated and immediately recovered. As for the breakdown, it was not possible to make a judgment based on images, and it took time for the investigators to go to the site to investigate the cause.

[0004] It is an object of the present invention to provide an elevator remote monitoring device capable of specifying the cause of a fault even if the fault has occurred temporarily.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a surveillance camera installed in an elevator machine room for photographing the state of each equipment of an elevator, and an image photographed by the surveillance camera. Recording means for recording, a monitoring terminal for monitoring the operating state of the elevator, transmitting a failure signal and an image before and after the failure of the equipment recorded in the recording means when an abnormality occurs in the elevator, and provided at a remote location A remote monitoring device comprising: a control center having a display device for receiving, via a communication line, an elevator failure signal detected by the monitoring terminal and images before and after the failure of each facility device through a communication line; and When a failure occurs, a display device for displaying a failure signal sent from the monitoring terminal and an image before and after the occurrence of the failure is provided.

As described above, the elevator remote monitoring device according to the present invention can quickly identify the cause of a failure that has occurred temporarily and has been recovered immediately.

[0007]

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

FIG. 1 is a block diagram of a system for implementing an elevator remote monitoring device according to one embodiment of the present invention. A plurality of surveillance cameras 11a to 11n installed in the equipment of the elevator 1 and photographing the state of the elevator equipment, a recording device 13 for recording the state of the elevator equipment photographed by the surveillance cameras 11a to 11n, and monitoring the state of the elevator 1 And a control center 4 connected to the monitoring terminal 12 via the communication line 3. The control center 4 includes a receiving unit 41 for communicating with the monitoring terminal 12, and a display device 42 for displaying the details of the failure received by the receiving unit 41 and the images recorded by the monitoring cameras 11a to 11n.

[0009] The monitoring cameras 11a to 11n are installed in each device in the elevator 1, and constantly photograph the status of the device in the elevator 1. The photographed images are recorded in the recording device 12 that records the images of the monitoring cameras. The image recorded in the recording device 12 is retained for an arbitrary preset recording time. Images for which the recording time has elapsed are deleted. The recording time can be arbitrarily changed. The image stored in the recording time 13 can be retrieved from the terminal device 12 for each time or each monitoring camera, and the image can be extracted.

Here, a description will be given of a case in which a device in the elevator 1 is out of order, for example, a door cannot be closed.

If the elevator doors cannot be closed,
The monitoring terminal 12 detects the failure,
The image taken before and after the occurrence of the failure and the details of the failure taken out of the images captured by the camera that is capturing the door are transmitted to the reception unit 41 in the control center 4 via the communication line 3. The receiving unit 41 that has received the failure content and the image transmits the failure content and the image to the display unit 42. The display unit 42 that has received the failure content and the image displays the name and address of the building in which the elevator 1 is installed, the name of the device in which the failure has occurred, and plays back the received image at the same time. The operator of the control center 4 determines the cause of the failure from the displayed contents and the image, and if dispatch is necessary, instructs a dispatcher who is waiting at a dispatch base (not shown) to dispatch. When the operator wants to view the current status of the elevator door, the operator performs an image display operation on the display unit 42. The display unit 42 that has performed the image display operation transmits an image request signal to the receiving unit 41. Upon receiving the image request signal, the receiving unit 41 transmits the image request signal to the monitoring terminal 12 via the communication line 3. The surveillance terminal 12 that has received the image request signal displays the image of the surveillance camera 11a photographing the elevator door on the operation unit 42 via the communication line 3 and the reception unit 41 in real time, so that the operator can You can check the current situation. Further, the image captured in the past is stored in the operation unit 42.
, The operator inputs the name of the equipment to be displayed, the display start time, and the display time from the operation unit 42 as an image search operation. The operation unit 4 where the image search operation was performed
2 transmits an image search request to the receiving unit 41. The receiving unit 41 that has received the image search request transmits the image search request to the monitoring terminal 12 via the communication line 3. Upon receiving the image search request, the monitoring terminal 12 extracts necessary data from the images stored in the recording device 13 based on the equipment name, display start time, and display time input from the operation unit 42. Operating unit 42 via communication line 3 and receiving unit 41
Send to The operation unit 42 reproduces the received image.

As described above, when a failure occurs, an image taken by a monitoring camera installed at the failure location is displayed simultaneously with the content of the failure, so that a failure that has occurred temporarily can also be performed.
The cause of the failure can be specified.

In the above-described embodiment, the operator of the control center 4 confirms the image data. However, the normal image is stored in the recording device 13 in advance, and the monitoring terminal 12 detects the failure. At this point, the failure image is compared with the normal image, and only when there is a change, the failure image is automatically transmitted from the monitoring terminal 12 to the operation unit 42 in the control center 4. Good. By doing so, it is possible to reduce the time required to specify the failure content.

Further, a failure determination function is added to the recording device 13 in the above-described embodiment, and images sent from the monitoring cameras 11a to 11n are compared with previously stored normal images, and there is a change in the images. In this case, for example, it is possible to detect the flickering of the fluorescent lamp in the car and to display a failure in which the mechanical sensor cannot be detected on the operation unit 42 of the control center 4.

[0015]

As described above, according to the present invention, the cause of a failure that has occurred temporarily can be specified. In addition, when a failure occurs, it can be automatically displayed on the operation unit, thereby enabling a short-time recovery. further,
Failures that cannot be detected by mechanical sensors can be displayed on the control unit of the control center.
