摘要
设计了一种基于LabView的地磁场异常监测系统,介绍了监测系统的硬件结构、软件设计流程、方位值计算模块、异常报警模块、数据保存模块。通过磁铁模拟干扰地磁场的实验,验证了所设计监测系统的准确性。
Most earth magnetic field monitoring instruments use hardware to complete calculating azimuth,alarm and data preservation.An earth magnetic field monitoring system is designed based on LabView.Hardware structure,software flow,direction calculation,alarm module,data preservation module are introduced.Correction of the monitoring is verified by the simulation experiment using magnet.The monitoring system is easy to expand and integrate.The format of monitoring data is simple.The system has a wide application foreground in the domain of earthquake monitoring and prediction.
