基于CAN总线的铁路道口控制系统

Research of Railway Crossing Control System Based on CAN Bus

针对现有铁路道口信号控制系统"定点报警"方式对快速列车和慢速列车的速度不能识别,造成道口关闭时机不合理、影响道口通过效率等问题,提出了一种基于CAN总线技术的单线铁路区段道口控制系统解决方案:使用"定时报警"方式,并模块化设计单线铁路区段道口信号控制系统。道口信号控制系统在列车接近道口传感器时,采集列车的速度并适时启动报警。实验表明,该系统能实现设计要求,提高道口通过效率。

It is difficult for present railway crossing signal control system to identify the fast train and slow train by ＂Fixed-Point Alarm＂ mode, which results in inefficiency during closing and passing time. A solution of crossing control system in single track railway zone based on CAN bus is proposed, by ＂Timing Alarm＂ mode and modular design. When the train approaching the crossing sensor, the crossing signal control system alarms timely according to the train speed. The experiments show that the system achieves the design requirements and improves passing efficiency at crossing.
