Elevator information display device

Abstract

The invention provides an elevator information displaying device which is corresponding to the operation state of the elevator. The displaying device can effectively display the information such as the current position and the operation direction of the elevator and the image information from the camera inside the elevator cage; the brightness of the displaying device can also be adjusted according to the use condition of the elevator so as to defer the aging of the displaying device; and the actual working time of the displaying device is transmitted to the monitoring center for management, thereby adopting corresponding measures such as change the displayer before the displayer fails. The invention is provided with a first displaying picture for displaying the operation information of the elevator on the whole panel of the displayer; and a second displaying picture for displaying after synthesizing the information such as the image of camera inputted by an image input device with the operation direction and the current position of the elevator. The first displaying picture and the second displaying picture are switched for displaying according to the operation state of the elevator. The brightness adjusting device of the elevator is controlled to adjust the brightness of the displaying device and then summarize the lighting time of each brightness after the adjustment, and then the summarization is sent to the monitoring center.

Description

technical field [0001] The present invention relates to an elevator display device for displaying various information in an elevator car or in an elevator lobby. Background technique [0002] In the prior art, as a device for displaying the running direction or current position of the elevator, for example, the following technical solution has been proposed, which installs an operation panel for registering the elevator destination floor near the entrance and exit of the elevator car, and On the upper part of the operation panel, the current driving position and driving direction of the elevator are displayed with indicator lights such as LEDs. In addition, in addition to the device for displaying the running position or running direction of the elevator, as a device for providing information in the form of a camera image or an image, for example, the following technical proposals have been proposed in which a display device such as a liquid crystal display is added to the e...

Problems solved by technology

[0006] In the prior art described above, in order to add an additional display device to the elevator car, it is difficult to provide information at a low cost because of the need for installation work and the expense required for the additional device.

In addition, since there will be multiple display devices after the expansion, it is necessary for elevator passengers to recognize information on multiple display devices, which may seem inconvenient

Moreover, since the image display equipment generally adopts a liquid crystal display, etc., and the elevator usually runs continuously for 24 hours, there are still problems such as brightness deterioration due to long-term continuous operation, which will affect the service life.
