Elevator lift car illumination diagnosis device

Abstract

The invention relates to an elevator lift car illumination diagnosis device, which comprises a camera (106), a detecting device (108), a storage device (112), a control device (110) and a communication device (114), wherein the camera (106) shoots the inside of a lift car (102) provided with an illuminating device (104), the detecting device (108) detects the brightness of an image shot by the camera, the storage device (112) stores detecting conditions and an initial brightness value, the control device (10) is used for comparing the brightness value detected by the detecting device with the initial brightness value, carrying out diagnosis on the illumination of the lift car on the basis of a comparison result and uploading the image shot by the camera into the control device (110) arranged in a server (120) connected with a network, and the communication device (114) is communicated with an external terminal. When the brightness difference is greater than a designated value, the control device determines the illumination fault grade on the basis of phenomenon occurrence frequency, and the communication device notifies a portable terminal of maintenance personnel of the fault grade and points to the interlinkage of the server. Therefore maintenance personnel can observe the condition inside the lift car on line in time and can take corresponding measures.

Description

technical field [0001] The present invention relates to a lighting diagnosis device for an elevator car, which includes a camera for photographing the interior of the car provided with lighting; and a detection device for detecting the brightness of the image captured by the camera. Background technique [0002] Japanese Patent Publication No. 2008-44697 discloses a device for diagnosing the lifetime of fluorescent lamps in elevators. In this patent publication, it is described as follows: "An image processing device for an elevator has an imaging device for photographing the interior of the car; an image segmentation unit for dividing the image captured by the imaging device into four or more regions; An image storage unit; a luminance calculation unit for calculating the luminance of each area image, characterized in that it has an image luminance comparison unit which compares the luminances of the stored images at intervals of the first time period; When the amount reac...

[0003] However, since the above-mentioned device for diagnosing the lifetime of fluorescent lamps in elevators compares the brightness changes before and after the first time period, although it can detect the flickering of fluorescent lamps, it cannot detect the deterioration of the light source gradually dimming.

In addition, the above-mentioned elevator fluorescent lamp life diagnosis device notifies the monitoring center of the detection results, and the monitoring center arranges maintenance personnel to carry out maintenance, which will bring a long time lag
