结合实际工作经验,总结了GMS-07综合电磁观测系统主机ADU-07e的主要结构特点,以及主机自检进行观测系统工作状态检查的情况,介绍该观测系统在野外观测过程中的注意事项,梳理常见故障的现象和排除方法;通过实例说明无法自检出的未接中心电极和磁道斩波器故障引起的资料异常。故障检测方法同样适用于GMS-07电磁观测系统常规大地电磁野外施工。
Based on the actual working experiences, the main structural features of ADU-07e, the host of GMS-07 integrated electromagnetic observing system, as well as the inspection of the working status of the observing system by the host self-test are summarized. The precautions during the field observation of the observing system are introduced, The phenomenon of common faults and the way to eliminate them. An example is given to illustrate the data anomalies caused by the faults of the missed center electrode and the track chopper that can not be detected by themselves. Fault detection method is also suitable for GMS-07 electromagnetic observation system conventional geomagnetic field construction.
