摘要

基于当代地震电磁扰动有关理论,地震临震前会引起地下电磁场发生变化,电磁扰动观测在地震监测预报工作中能够发挥较好的短临预报作用。本论文旨在开发研制基于地下交变电磁场数字化电扰动仪。CNEM08-I电扰动仪采用低功耗、高性能的工控机作为硬件平台,选取大容量存储器,对地下电磁场变化进行实时观测,连续数字化采集。编制了数据采集系统软件及与观测系统配套使用的分析系统软件,自动将采集数据通过网络传输到分析控制中心,同时对多个基站的观测数据进行显示、统计分析,可进行分段统计平均值、最大值、总量,可对异常进行统计分析。
Based on current theory of seismological electromagnetic disturbance,a digitizing electric disturbance device(CNEM08-I) which measures alternative electromagnetic field underground has been developed.By use of industrial computer of low power dissipation and high performance as hardware platform as well as large capacity memory,it can observe the electric disturbances in real time with continuous data collection.The paper describes data collecting software and analysis system which can transfer collected data to the center of analysis automatically through network.Data in many stations are displayed simultaneously,and analyzed by using statistic technique.
