摘要

讨论了一种微型便携式地震仪的设计思路 ,该仪器具有本安防爆 ,重量轻、低功耗、高精度、高采样率等特点 ,内置三分量检波器 ,采集数据原位数字化且原位存储 ,能极大限度地抵抗外界干扰 ,提高采集信号的信噪比 ,实现了地震勘探检波一体化的理想采集条件。该仪器适用于恶劣环境条件下的高精度浅层多波勘探 ,如岩土体强度的原位测试、残余煤厚探测与工程检测等。通过实际应用证明该仪器应用范围广阔
A miniature portable seismograph with its intrinsic design for safety,explosion proof is designed.The instrument has the characteristics of low weight,low power,high accuracy and high speed,and a 3 componented geophone is combined in it.As it can convert analog signals to digital datum and store the datum in original site,it has the extremely ability to resist the outside interference,increase the SNR of seismic signal,and reach the ideal condition of integrated sampling and effectively overcome the bottle neck effect of the general seismic data sampling system.This seismograph is best suited for high accuracy shallow layers multi wave exploration in complicated environment,such as testing the intensity of rock and soil block in site,prospecting the thickness of the residual coal and the engineering detecting etc.It is confirmed by field tests that this seismograph is practical and cost effective.
