地铁巡检线扫激光传感器控制装置设计与实现

地铁轨道日常巡检中需要2台线扫激光传感器实现地铁轨道面的图像扫描,2台线扫激光传感器同时采样时激光叠加部分会出现干扰,导致该部分采样数据异常。设计一种通过单片机控制2台线扫传感器采样的控制装置。装置通过单片机IO口输出异步时序控制线扫传感器异步采样,通过自带网口和扩展网口读取扫描数据,通过串口控制4G/GPRS模块将数据远程传输到巡检自动化控制后台。

In the daily inspection of subway track,two linear scanning laser sensors are required to realize the image scanning of subway track surface.When two linear scanning laser sensors sample at the same time,the laser superposition part will be interfered,resulting in abnormal sampling data of this part.A control device is designed to control the sampling of two linear scanning sensors through a single chip computer.The device outputs asynchronous time sequence control line scan sensor asynchronous sampling through the single chip microcomputer IO port,reads the scanning data through its own network port and extended network port,and transmits the data remotely to the inspection automation control background through the serial port control 4G/GPRS module.
