基于遥感监测的机场防雷预警系统的设计

Design of an Airport Lightning Protection Early Warning System Based on Remote Sensing Monitoring

传统防雷预警手段精度较低,无法保障机场飞行安全,为此,本文设计了一种基于遥感监测的机场全域范围防雷预警系统。在系统硬件方面,使用传感结构的雷电预警仪、闪电定位仪设计雷电预警单元,使用CC2540F256RHAR无线射频芯片设计组网的通讯模块;在系统软件方面,通过遥感监测影像预处理技术与雷电概率预测技术完成机场目标区域的雷电临近预警。实例应用结果表明,本文设计系统可精准预警即临近雷电的发生时间和地域,也可准确定位局地发生雷电时的精确位置、轨迹、次数及大小,具有良好的稳定性,满足机场雷电安全防护的预警需求。

Due to the low accuracy of traditional lightning warning methods,the safety of airport flights cannot be guaranteed,so a lightning early warning system based on remote sensing monitoring is designed for the whole region of the airport.In terms of system hardware,the lightning warning unit is designed using the lightning warning instrument and lightning locator with a sensing structure,of which the communication module for networking is designed using the CC2540F256RHAR radio frequency chip.While in terms of system software,the lightning nowcasting warning of the airport target area is accomplished through remote sensing monitoring image pre-processing technology and lightning probability prediction technology.The application results indicate that the system designed in this paper can accurately predict the occurrence time and region of approaching lightning,and can also accurately determine the exact location,trajectory,times and intensity of local lightning,and has good stability to meet the early warning requirements of airport lightning safety protection.
