摘要
为进一步补充和完善现有的闪电磁场观测设备,文中介绍了一种基于磁阻传感器HMC1002的磁场测量系统,实现了对闪电磁场波形的快速采集存储。文章重点阐述了磁阻传感器的基本原理和探测系统的结构组成,通过在广东省从化地区开展的野外人工触发闪电和自然闪电观测试验的测试,分别获得了完整的触发闪电和自然闪电的磁场波形数据,通过与正交环形天线同步观测磁场数据的比较,发现两者数据一致性较好,表明了该系统可以对闪电磁场进行有效测量。
Aiming to further complement and improve the existing lightning magnetic field observation equipments,a magnetic field measurement system based on magnetoresistive sensor chip HMC1002 is designed in this paper,which realizes the fast acquisition and storage of lightning magnetic field waveform.The basic principle of the magnetoresistive sensor and the structure of the detecting system are emphatically introduced.The complete magnetic field waveform data of triggered lightning and natural lightning have been obtained respectively by the test of artificial triggered lightning and natural lightning in Conghua area of Guangdong Province.And through comparing with the magnetic field data observed by the orthogonal circular antenna,the data consistency of the two is good,indicating that the system can effectively measure the lightning magnetic field.
