摘　　要：BTM(查询应答器)是列车控制系统的关键组成部分,一旦发生故障,可能导致列车失去定位、触发紧急制动或限速运行,严重影响地铁的运行效率。针对这一问题,探讨了冷备冗余天线、热备冗余功放设备和头尾BTM冗余3种模型的优化改进。研究结果表明,通过头尾BTM冗余改造,不需要增加额外的车载设备,也能满足行业需求。模型验证表明,在单端BTM故障的情况下,列车仍可维持以CBTC级别运行,从而确保地铁系统的调度不受影响,不因降级而中断运营。BTM(Query Answerer)is a key component of the train control system.Once a fault occurs,it may cause the train to lose its position,trigger emergency braking,or run at a limited speed,seriously affecting the efficiency of subway operation.Regarding this issue,optimization and improvement of three models were discussed:cold backup redundant antenna,hot backup redundant power amplifier equipment,and head tail BTM redundancy.The research results indicate that through the head and tail BTM redundancy transformation,there is no need to add additional onboard equipment,and it can still meet industry demands.Model validation shows that in the event of a single ended BTM failure,trains can still maintain CBTC level operation,ensuring that the scheduling of the subway system is not affected and operations are not interrupted due to downgrading.
