地震数据采集器关键技术研究

Key technology research of seismic data acquisition system

介绍为满足地震监测要求而应用于地震数据采集器设计的一些关键技术,详细分析影响地震数据采集器的信噪比、时钟精度和标定系统精度的原因,并提出相关设计方法,给出设计实例。

In this paper, some key technology of seismic data acquisition system are introduced to meet the requirements of earthquake monitoring. The factors which affect the signal to noise ratio, clocking accuracy, and calibration system of seismic data acquisition system are ana- lyzed. And the method of design is put forwards. A design example is given.
