摘要

银川地震台数字地震仪系统由地震计、GPS授时系统、VSAT卫星通讯网、EDAS-C24型数据采集器等组成。其供电方式采用市电和发电机供电两种方式。避雷措施采用电源避雷和在观测室架设避雷网方式来实现避雷。总结了银川地震台数字地震仪系统在日常工作中数据传输、转发、存盘、波形质量等方面遇到的11种故障及排除方法,可供其他相关地震台站借鉴。
The system of the digital seismograph in Yinchuan seismological station is composed with the seismograph,the GPS time service system,the VSAT satellite communications net and the EDAS-C24 data collection and so on.Its power supply uses two ways of the city electricity and the generator supply power. The measure of the lightning protection uses the power lightning protection and putting the lightning protection network in the observation room to realize the lightning protection.We summarized 11 kinds of the breakdowns and the elimination method of data transmission,the repeater,saved in disk and wave quality and so on appearing in the routine work of the digital seismograph system in Yinchuan station.It might give some reference for other related seismological station.
