摘　　要：以提高城市轨道交通列车运营管理自动化水平、降低列车使用能耗为主要目标的列车远程唤醒休眠功能,主要包含休眠后的列车位置持续获取及监督、列车唤醒命令获取等。在分析现存系统实现方式的优缺点基础上,提出一种全新的列车唤醒休眠系统的实现方案。利用此系统可以代替既有应答器传输单元、车载测速单元实现休眠时车辆位置的持续获取与实时监督,并借助此系统的双向通信机制代替WLAN(无线局域网)或LTE(长期演进)接收来自控制中心的ATS(列车自动监控)唤醒命令。本系统可适用于既有轨道交通列车全自动运行改造项目及新建列车全自动运行项目,在实现列车远程唤醒功能的同时,简化了列车休眠的车地设备设计,提高了休眠列车的定位精度,降低了列车休眠时的功耗。In order to improve the automation level of urban rail transit train operation and management,and to reduce the train energy consumption,the train remote wake-up and sleep function mainly includes continuous acquisition and supervision of train position during sleep,acquisition of train wake-up command.Based on the analysis of the advantages and disadvantages of existing system implementation,a new implementation scheme of train wake-up and sleep system is proposed.This system can replace the existing balise transmission module and on-board speed measurement unit to realize the continuous acquisition and real-time supervision of vehicle position during sleep,and use the bidirectional communication mechanism of this system to replace WLAN(wireless local area network)or LTE(long-term evolution)to receive the ATS(automatic train supervision)wake-up command from the center.The system can be applied to the automatic transformation project of existing rail transit trains and the new FAO project.This system can not only realize the function of remote wake-up,but also simplify the design of the vehicle-ground equipment of the sleeping system,improving the positioning accuracy and redu-cing the power consumption of the train during sleep.
