UM71无绝缘轨道电路投入运用以来 ,现场维修使用单位尚无检测手段 ,假故障、软故障现象时有发生 ,影响了设备的应用效率。因此 ,对 UM71无绝缘轨道电路系统设备的功能指标 ,进行现场测试及老化试验 ,排除假故障、软故障对运输生产的干扰 ,将具有积极的意义。UM71综合自动测试系 UM71 non-insulated track circuit put into use, the field maintenance units without testing means, false, soft failure occurs from time to time, affecting the efficiency of the equipment. Therefore, it is of great significance to carry out on-site tests and aging tests on the functional indexes of UM71 non-insulated track circuit system equipment to eliminate the interference of false faults and soft faults on transport production.
