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.
