信标读取链路健康管理技术研究

Research on Health Management of Transponder Interrogator Chain

车载信标读取链路是列车自动防护系统(ATP)的重要组成部分,一旦信标读取链路出现问题,就会给系统定位带来影响,严重情况下甚至导致列车退出运营。从研究信标读取链路健康状态评价的数学模型、健康度计算,以及健康预测方面,对信标读取链路进行设备健康管理研究,可以做到提前发现、提前处理,减少信标读取链路故障的发生,提高运营效率。

The on-board transponder interrogator chain is one important part of the Automatic Train Protection(ATP)system.Once the transponder interrogator chain breaks down,the positioning of the system will be affected,which might directly lead to the train’s withdrawal from service even in serious cases.Health management of the transponder interrogator chain is studied,including a mathematical model for health evaluation,health calculation and health prediction of the transponder interrogator chain.So,the failures of the transponder interrogator chain can be detected and handled in advance,thus reducing the failure rate of transponder interrogator chain and enhancing operation efficiency.
