青藏铁路ITCS车载台通信监控系统研究与开发

Research and development to Qingzang Railway Cmmunication and Monitoring System of ITCS vehicle terminal

无线列车控制数据传输是增强型列车控制系统(ITCS)的重要环节。目前,移动无线模块(MRM)设备作为青藏铁路ITCS中无线列车控制数据传输的车载终端设备,已经成功运用。基于青藏铁路ITCS相关特点,对ITCS车载台监控系统进行了方案设计及具体的软件和硬件设计。通过在MRM外部和机务段站场内添加监测设备的方式,解决了MRM设备的软硬件全系统的出入库检测问题,并可以直接转发到检测机房,使机房人员可以直接观察到在站场内的MRM主机内部运行的情况,便于间接分析故障,以实现MRM主机的出入库检测功能。

Wireless train control data transmission was an important part of ITCS （Increased Train Control System）. As the wireless train control data transmission vehicle terminal of ITCS in Qinghai-Tibet Railway, MRM equipment has been successfully put in use. It was based on the characteristics of the Qinghai-Tibet Railway and GSM-R network usage situation. At the same time, based on the Qinghai-Tibet Railway ITCS related features, it was to put forward a tentative design and the specific software and hardware design to ITCS Vehicle Terminal Monitoring System. By adding monitoring equipment to the external MRM and the locomotive depot station site, the storage testing to the MRM whole Software and Hardware System could be totally achieved and transmitted directly to the testing room, which was enabled the engine room staff to discover directly the MRM internal operations in the station site and facilitates them to analyze the fault and achieve the storage testing function of MRM host computer.
