摘要
地震检波器信号调理电路是关乎地震数据采集站技术性能指标最为重要的电路。他不仅关系到地震信号频率范围、地震数据的精度,更关系到地震仪器的稳定性和抗干扰能力。本文从地震信号特性、地震数据采集基本要求及野外电子产品工作环境要求出发,详细描述地震仪器的数据采集单元中模拟地震检波器输入电路的功能要求与设计方法,开发出满足当今高精度地球物理勘探开发需求的地震数据采集记录仪器。
Geophone signal conditioning circuit is the most important circuit related to the technical performance index of seismic data acquisition unit.It is not only related to the frequency range of seismic signals and the accuracy of seismic data,but also related to the stability and anti-interference ability of seismic instruments.Starting from the characteristics of seismic signal,the basic requirements of seismic data acquisition and the working environment requirements of field electronic products,this paper describes in detail the functional requirements and design method of analog geophone input circuit in the data acquisition unit of seismic instrument,and develops a seismic data acquisition and recording instrument that meets the needs of today’s high-precision geophysical exploration and development.
