列车试验线末端防冒进系统应用分析与优化

Application analysis and optimization of anti-overrunning system for train test line terminal

针对列车试验线末端防冒进系统运行考核过程中发现的卫星定位信号不稳定、连线复杂及操作软件等问题,进行分析探讨,从更换卫星定位模块、增加卫星频段,重新选择速度信号采样方式及更新升级操作软件等方面进行了优化改进。

In order to solve the problems of instability of satellite positioning signal,connection complexity and the lack of operation software,which are found in the operation and examination of the anti-overrunning system for train test line terminal,this paper analyzes and discusses the problems.The system is improved by replacing the satellite positioning module,increasing the satellite frequency band,re-selecting the sampling mode of the speed signal and updating the operation software.
