摘要
本文针对列车运行控制系统的无线通信在ISM 2.4G频段内易受干扰的问题,提出一种满足实际需求的简化监测开发方案,对分析列车控制系统的无线通信具有重要意义。通过对监测软件的架构和信令交互进行分析,给出监测软件的主流程,并完成软件的开发。该软件已投入到北京地铁CBTC系统无线通信的现场测试中,测试结果证明监测软件具有完整、准确的测试能力。
Because the communication of Communication Based Train Control System in ISM 2.4G can be easily interfered, a simplified scheme which can satisfy the real demand is proposed, which is important to the analysis of the wireless communication in CBTC. According to the analysis of the architecture and the signal interaction of the monitor software, the flow diagram of the monitor software is shown, and the monitor software is developed. The software is put into service of field tests in wireless communication of CBTC in Beijing Subway, it is proved that the monitor software is complete and accurate.
