摘要
运用DSP技术,实现了铁路车站信号灯工作状况的安全性检测和控制.运用电力线载波通信技术实现了信号灯状态的远程传输和监控,采用CAN总线技术使各车站的信号灯及区间的信号灯统一纳入一个网络管理系统中.本文描述了系统的原理,给出了系统的硬件电路和算法,实验表明该系统具有实时性和稳定性的特点.
Based ond CAN bus the automatic railway signal lamps detecting system is presented in this paper. The DSP technology is applied to this system. It can both control and test the status and security of the signal lamps in the railway station. Power line carrier is used for carrying out the long_distance test and control. In this system, CAN bus connects all the signal lamps in the railway station, and it forms a network manage system. In addition, the system principle is described and the design of the hardware and arithmetic are presented. The experimental result indicates that real_time and stability of this system satisfies the requirements in engineering.
