Design and Implementation of Active Lightning Early Warning System

在雷电防护措施中通常会采用主动式雷电预警系统,在综述国内外雷电预警系统研究现状的基础上,设计开发了对雷电可知、可测、可控的主动式雷电预警系统,其中雷电预警仪优化去除了同步信号发生器、电机接地电刷,稳定性得到了提升;通信控制终端实现了采集大气电场仪数据、本地调试升级等功能;终端设备电源进行了防雷电路设计,通过8/20电流冲击试验证明了自身防雷能力;设计了直流电场实验环境对雷电预警仪进行测试和标定;设计了雷电预警系统软件平台,并分析了一次真实的完整的雷击时序图,重点进行了预警阶段的分析;最后结合雷电预警信息,设计了远程实时控制升降避雷针、三色声光报警灯的技术路径。该系统在宁夏等处得到了很好的应用,达到了预期的效果。

In general,active lightning warning system is utilized in lightning protection measures.An active lightning warning system that is knowable,measurable and controllable to lighting was developed through reviewing the research status of the lightning warning system at home and abroad.To be specific,a synchronizing signal generator and a motor ground brush were eliminated by optimizing the lightning warning device,so sa to improve the stability.And functions such as acquisition of atmospheric electric field instrument data and upgrading of local commissioning could be implemented in the communication control terminal.Besides,lightning protection circuit was also designed for the power supply of the terminal equipment.Its lightning protection capacity was proved by the 8/20 current impacting test.Moreover,the lightning warning instrument was tested and calibrated in the DC electric field experiment environment.Meanwhile,by designing software platform for the lightning warning system,a real and complete lightning stroke sequence diagram was analyzed for analyzing the warning stage emphatically.At last,technical paths concerning remote and real-time control of lifting lightning rods as well as tricolor soundlight alarm lamps were designed in conjunction with lightning warning data.With good applications in Ningxia,expected results are witnessed in the proposed system achieves.
