摘要:

工业铁塔广泛应用于电力高压输电线、通信天线等领域，但塔身高度和结构特点易使其成为雷击目标。雷击现象具有突发性和强破坏性，其危害与雷电信号的冲击特性相关，如电流强度大、持续时间短等。针对当前雷电监测现状，利用无源雷电流传感器采集雷电流信号，设计了一种新型红外光纤调制解调器处理雷电信号，通过 S/PDIF（Sony/Philips Digital Interconnect Format）光纤稳定传送至检测终端，实现在复杂工业环境下雷电信号的检测处理。应用 5G 技术将测量数据传输到云服务器进行分析，用户可通过手机 App 或 Web 界面访问云服务器， 实现雷电远程在线监测。实验结果表明，工业铁塔发生雷击事件时，该监测系统能够准确记录雷击时间、次数和雷电流强度。这为广泛开展雷电活动监测工作提供了一种稳定、可靠的技术手段。

Abstract:

Industrial iron towers are widely used in high-voltage power transmission lines， communication antennas， and other fields. However， the height and structural characteristics of the towers make them susceptible to lightning strikes. Lightning strikes are sudden and highly destructive， and their hazards are related to the impact characteristics of lightning signals such as high current intensity and short duration. In response to the current situation of lightning detection， a passive lightning current sensor is applied to collect lightning current signals. A new type of infrared fiber optic modulator-demodulator is designed to process lightning signals by transmitting them stably to the detection terminal via S/PDIF optical fiber for lightning signal detection and processing in complex industrial environments. Finally， utilizing 5G technology， the measurement data is transmitted to a cloud server for analysis. Users can access the cloud server via a mobile App or Web interface for remote lightning monitoring. Experimental results show that when lightning events occur on industrial iron towers， the monitoring system can accurately record the timing， frequency， and intensity of lightning strikes， providing a stable and reliable technical means for widespread lightning activity monitoring.
