摘　　要：上海轨道交通11号线定位信标丢失故障频繁发生,影响了正线的运营效率。以11号线为研究对象,对基于通信的列车控制(CBTC)信号系统列车定位丢失的原因进行分析,并对列车定位装置的天线和轨旁应答器进行了改进。提出了改造一体式电缆、调整设备的水平度、加装减震器三项整改措施,加强设备的维护力度,以保障CBTC系统的正常运行状态。The frequent location beacon loss failures on Shanghai rail transit Line 11 directly affect the main line operation efficiency.With Line 11 as the research object,the causes for train positioning loss based on CBTC signal system are analyzed,the antenna and trackside transponder of positioning device are improved.Then,three rectification measures are proposed,including transforming the integrated cables,adjusting the equipment level and installing the hock absorber,the operation status of CBTC equipment is ensured by strengthening the maintenance of equipment.
