An LCD-type electronic stop sign fault self-repair system and its application method

Abstract

The invention discloses a fault self-repair system for an LCD-type electronic stop sign, which relates to the technical field of bus station waiting display, and includes a fixing structure for fixing and installing the display device on the frame. Bolt, the end of the bolt is rotatably connected with a pressing part, the end of spring one is fixedly connected with a moving plate, the side of the moving plate is fixedly connected with a pressing arm, and the end of the pressing arm runs through the side of the pressing part and is fixedly connected There is an elastic board, the elastic board includes a bending part 1 and a bending part 2, the end of the elastic board is fixedly connected with a plug board, the outer wall of the frame 1 is fixedly connected with a connecting board 1 for the plug board to pass through, and the side of the frame 1 is opened There is an abutting groove for the bending part to abut against. Through the cooperation between the above-mentioned structures, the present invention has the advantage of not directly contacting the display device with the inner wall of the frame, but using the elastic plate as the main connecting part, effectively playing the effect of vibration buffering.

Description

technical field [0001] The invention relates to the technical field of waiting display at bus stops, in particular to an LCD-type electronic stop sign fault self-repair system and a method for using the same. Background technique [0002] The bus shelter is a public facility specially built for urban citizens waiting for the bus. It provides a place for people to wait for the bus and provides convenience for the bus shelter. The bus station should fully reflect the people-oriented design concept. Its design should include the passenger waiting platform, roof, stop signs, area maps, waiting seats, commercial or public service advertisements, lighting systems, and bus-only roads in front of the platform. [0003] When the LCD display screen used in the existing bus station shelter breaks down, it needs to be found in time and repaired in time. Traditional detection methods rely on personnel inspection to see the working conditions of the LCD display. In order to improve the ...

AI Technical Summary

Problems solved by technology

In order to improve the self-detection ability of the LCD display screen, the use of PLC to detect the operating voltage, current, temperature and other working conditions of the display screen gradually appeared, resulting in an increase in the weight of the LCD display screen

When fixing the LCD display, usually the frame of the LCD display is directly connected with the frame by bolts, so that the LCD display is extremely vulnerable to damage caused by the vibration of the frame
