摘要
分析应答器传输系统的信号特点,搭建FSK信号解调的Simulink等仿真环境,结合应答器误码故障发生时列控车载BTM设备记录模块采集的数据,对应答器上行链路误码问题进行特征分析,得到信号的频谱、波形等特征,为现场的故障排查提供分析方法,对设备的优化提供指导。
In this paper, the signal characteristics of the balise transmission system are analyzed, and the simulation environment such as demodulation of FSK signal by Simulink is built. When the balise bit error occurs, the data collected by the BTM equipment recording module is used to carry out characteristic analysis of the bit errors for Up-link and get the characteristics of the signal spectrum, waveform, etc., which provides analytical method for on-site troubleshooting, and also provides guidance for equipment optimization.
