基于CAN总线的地铁杂散电流监测系统设计

The Stray Current Monitoring System Based On Can Bus

分析了地铁杂散电流的形成及危害,阐述了地铁杂散电流监测控制系统的功能,设计了基于CAN总线的地铁杂散电流的监测系统。论文对该系统的下位机软硬件结构,PC-CAN接口卡以及上位机软件进行了设计。该系统实现了数据的实时采集,液晶显示,越限报警,CAN总线传输和在一定条件下向牵引变电所内的智能排流柜输出控制量等功能。该系统具有可靠性高,抗干扰能力强等优点。

This paper analyses the form and hazard of subways stray current, and expatiates the function of subways stray current monitor and control system, it also designs the set of subways stray current monitoring system based on CAN bus. The paper designs software and hardware structure of slave computer, PC-CAN interface and host computer software. This system realizes the function such as data real time acquisition, LCD display,alarming and outputting corresponding control signal to the cabinet of draining current in traction power station. The system has many advantages such as good reliability and anti-jamming etc.
