雷电预警系统在区域台站中的应用

The Application of Lightning Warning System in Regional Seismic Stations

雷电是台站仪器设备主要的安全隐患。雷电预警是指在雷电发生前约几分至数十分钟内及时发出预警信息,实现台站电源控制的自动切换,达到保护台站仪器设备免遭雷击损失的目的。雷电预警监控系统软件,是基于对雷电预警装置电场数据的实时监控,通过引入区域雷达回波强度动态分布图作为辅助判断,构成有效范围的雷电预警监控网,达到为区域台站雷电预警服务的目的。

Thunder is the major safety hazard of seismic station instruments. Lightning warning refers to give early warnings information about several minutes to dozens of minutes before the lightning strike,and then the station power swatches to protect equipment from lightning damage. The lightning warning monitoring system introduced in this paper achieves lightning warning for seismic stations nearby based on the real-time monitoring of electric field data and the radar.
