野外地震台站常见仪器故障的分析及排除

野外地震台站的仪器设备包括地震计、数据采集器、直流电源、交换机、通讯设备和避雷器等,由于野外工作环境不稳定,容易造成仪器设备出现故障,使得地震台网中心出现接收不到波形数据、波形数据断断续续、波形数据异常和波形走直线等现象。以新丰江遥测地震台网的野外台站为例,分析产生这些故障现象的原因,提出了排除故障的方法。

Analysis and elimination of the common fault of the instrument field seismic stations

The instruments of field seismic station comprise a seismometer, data acquisition unit, DC power supply, switches, communication equipment and lightning arrester equipment. Because the field work environment is not stable, it is easy to cause equipment malfunction, which results in the failure of receiving and processing waveform data by seismic network center. Taking the Xinfengjiang telemetered seismic network field station as an example, we analyzed the causes of these faults, and put forward methods of troubleshooting.
