地铁列车与地面数据接口故障研究

Study on the Fault of Subway Train and Ground Data Interface

为避免列车控制及监控系统通信接口在运营期间发生故障,文中对实际设计案例进行故障分析、处理和测试研究,总结出通信接口中复位电路、电源电路和时钟信号等硬件配置中的重要因素,以及程序初始化、堆栈和数组分配、访问指向等软件优化的关键点。

To avoid the occurrence of communication interface failure during operation of train control and monitoring system,this paper carries out the analysis,fault handling and test research of actual design cases,and summarizes the important factors in hardware configuration which includes the reset circuit,power supply circuit and clock signal in the communication interface,and the key points of software optimization which includes program initialization,stack and array allocation,access pointing.
