针对输变电杆塔等电力设施的雷电故障快速定位、雷电特征研究等需要一定数量的雷电接闪监测系统,设计了一种智能雷电监测系统.该系统由雷电信号采集模块、中心控制模块、显示模块、控制模块、储存模块、时钟模块和PC上位机模块等组成.设计合适的罗氏线圈,利用采集模块采集雷电信号,实现雷电的监测;以STM32F103ARM微控制器为主控制器,将采集到的雷电数据经过处理后,通过显示模块实现数据的显示,通过SD卡、时钟模块实现数据的存储和回溯查询;通过RS485总线将数据传送给PC上位机,实现远程的实时监控和数据记录.
Lightning detection system is required in specific situations such as fast location of lightning disaster on power trans- mission tower and lightning characteristics research. An intelligent lightning detection system including lightning signal collection module, centre control module, display module, memory module, time module and host computer module is implemented. A novel Rogowski coil is designed to use signals collected by collection module to detect lightning. The collected lightning data pre-pro- cessed by the master controller STM32F103ARM can be memorized and inquired if the SD card module, the time module and the display module are used. In addition, the remote real-time detection and data recording can be realized if the pre-processed light- ning data are transmitted to the host computer by the RS485 bus.
