摘要
为满足城市轨道交通列车制动系统通信过程中对数据传输可靠性和稳定性的要求,提出采用控制器局域网络(CAN)总线技术作为通信技术协议的方案。介绍CAN总线通信协议的特点,基于STM32芯片,设计CAN通信模块,用于城市轨道交通列车制动系统,并编写CAN通信程序,实现制动系统的互联互通,通过现场调试验证,CAN总线通信在可靠性、传输速度等方面都能达到使用要求。
To satisfy the transit train brake systemcommunication process requirements on reliability andstability,this paper makes proposals on solutions focusingon usage of CAN bus as communication technologyprotocol,and an introduction of the characteristics ofCAN bus communication protocol.Based on STM32chip,the CAN bus communication module of thetransit train brake system is designed,and the CANcommunication program is drafted,serving the purposeof achieving the interoperability and communicationsof the brake system.After site tests and inspections,theCAN bus communication reliability and transmissionspeed meet the use requirement.
