摘　　要：北京铁路局普速铁路实施TDCS列车占用丢失报警功能以来,误报警发生率较高。为减少误报警,让列车占用丢失报警功能真正发挥作用,在对大量误报警案例分析的基础上,针对目前频发的误报警场景,提出了本站增加采集邻站相邻区段轨道状态(站间联系条件)、增加区间信号机显示判定条件和车次追踪功能下放至车站的方案,在降低普速铁路TDCS列车占用丢失误报警率方面上具有可行性和实用性。Since the alarming function of TDCS rate of false alarms remains quite high. In order pancy alarming function, this paper puts forward train occupancy being lost has been implemented, the to reduce false alarms and fulfill the role of train occuthree proposals Firstly, the track states of the adjacent sections at adjacent stations, which are contact condition between stations, should be gathered. Secondly, the state of railway section signal should be taken as a necessary condition to determine the alarm. Finally, the station, instead of the TDCS center, is responsible for the train number tracing. Through a large number of case analysis of these solutions, it is demonstrated that the rate of false alarms can be effectively reduced.
