【摘要】 针对震磁前兆信息地磁总强度以及地磁各分量有异常显示,研制了海陆两用磁力仪系统,可分别应用于陆地以及海底磁场变化的长期监测。采用霍尔韦尔的AMR磁阻传感器构成三分量磁传感器,低功耗MSP430为处理器,具有低功耗、测量范围宽、大容量存储等特点。通过串口与上位机进行实时通信与数据显示,为震磁前兆研究提供具有实用价值的数据,为地震预测提供宝贵资料。更多还原

【Abstract】 For the anomalies display of geomagnetic intensity and various components of earthquake and earth’s magnetism precursor information,adual-magnetometer system of land and sea was developed.It can be long-term respectively applied to terrestrial and undersea monitoring of the magnetic field changes.Using AMR(Anisotropic Magnetoresistant) sensor to constitute a three-component magnetic sensor and low-power MSP430 for the processor,the system has many advantages which include low power consumption,wide measuring range,high-capacity storage,etc.Through the serial port host,computer and magnetometer can real-time communicate and display the data.The data have practical value for earthquake and earth’s magnetism precursor research,and provide valuable information for the earthquake prediction.更多还原
