铁路轨道信号发送与车载接收模拟系统

摘要

构建并实现基于DSP的铁路轨道信号的发送与车载接收模拟系统,该系统以浮点数字信号处理器TMS320VC33为数据处理核心,以定点数字信号处理器TMS320VC5509A为控制核心,实现铁路轨道信号的发送、传输、车载接收、译码以及执行上灯控制等,支持国内现有4种制式铁路轨道信号.该系统既可以为教学提供实验和演示,也可以为相关的研究提供一个平台.%In this paper,the DSP-based simulation system for railway signal transmission and on-board receiving is established and implemented.The system can simulate the working process of the railway signalling system,including signal sending, transmission, receiving, decoding and controlling of the eight-signal display device,thus supporting four existing railway signalling standards applied in China.The system can provide an experimental and demonstrating module for teaching purposes and also a platform for futher research and development.
