摘　　要：城市轨道交通中,应答器传输系统在列车运行过程中常因为设备故障,出现信标丢失的现象,导致无法对列车进行定位而引起列车制动,对线路运行造成极大的影响。本文利用STM32单片机设计了一种车载查询器故障诊断系统,通过采集查询器各端口数据进行分析,即可对查询器进行故障诊断。使用该系统可快速发现故障并及时处理,保证行车安全。系统设计完成后在地铁正线进行实测,验证了故障诊断系统的可靠性,证明该系统有良好的应用价值与实际意义。In urban rail transit, the balise transmission system often loses the beacon due to equipment failure during the train operation, resulting in the inability to locate the train and causing the train to brake, which has a great impact on the line operation. In this paper, a fault diagnosis system of the inquirer is designed with STM32 single-chip microcomputer. The fault diagnosis of the interrogator can be carried out by collecting the data of each port of the interrogator and analyzing it. This system can quickly find faults and deal with them in time to ensure driving safety. The actual measurement is carried out on the main line of the subway, which verifies the reliability of the fault diagnosis system and proves that the system has good application value and practical significance.
