临时地震台站故障的快速判别

Rapid Identification of Temporary Seismic Station Failure

许多专家在对一些地区进行研究时,发现研究区能够提供有效数据的台站密度远远不够,这就需要在这些研究区架设野外临时地震台站。而临时台站常常因各种因素造成波形异常、断记、缺数等故障而无法正常运行,所以如何快速判别并修复这些故障成为保证台站产出有效数据的关键。本文分析了临时地震台站的部分故障原因,并提出特定条件下的快速处理方法,为临时台站的架设和巡检人员提供参考。

As more and more experts begin to pay attention to earthquake-prone areas, they are discovering that seismic station density is not sufficient in some key regions, and that there is a need for the installation of temporary seismic stations. Because the natural conditions and environment are very bad around these stations, equipment malfunction frequently otions cannot then run because the malfunctions can cause abnormal waveforms, record tnterruption, or data defects. Therefore, the rapid identification and repair of these failures is very important. In this paper, we introduce methods to quickly find and repair many of these failures from four aspects： power supply, seismic data acquisition system, GPS , and seismograph. The study provides a reference for the building and maintenance of temporary seismic stations.
