AI Technical Summary

Technical Problem

Existing rail transit indicator devices lack self-cleaning and intelligent maintenance functions, and the display screens are easily covered by dust and stains, affecting the accuracy of information transmission.

Method used

A modular structure was designed, comprising an electric guide rail, an electric slider, an adapter, a dust wiping rod, a main controller, a water pump, and a vibration motor. Automatic cleaning is achieved through the linkage of the electric slider and the adapter. The spraying of cleaning agent and the reciprocating motion of the dust wiping rod, combined with the vibration of the vibration motor, ensure the cleaning effect on the display screen surface.

Benefits of technology

It enables automated cleaning of the display screen, improves the cleanliness of the screen, reduces the adhesion of stubborn stains, enhances the accuracy of information transmission and the operational stability of the device, and simplifies the maintenance process.
