摘要
介绍了首都圈32个卫星台站的概况和数据传输的实现方法,阐述了数据采集器参数设定的有关问题,同时给出了不同类型地震仪测震观测技术指标。从原理上探讨了地震仪观测灵敏度和传递函数的测定方法,并对32个卫星传输台站传递函数的测定结果进行了分析。
General information and data stream of 32 stations whose data are transmitted by VSAT satellites are introduced, and some problems of parameter settings of data acquisition instrument are discussed. Then technical parameters of several seismographs are showed. At last the methods of measuring gain and transfer function of seismograph are discussed and the results of transfer function measurement of the 32 stations are analyzed.
