无人机输电线路巡线系统及应用研究

The application and research of line communication system based on microwave transmission

针对传统的人工巡检方法存在工作量大而且条件艰苦等缺点,设计了微波无线巡线监控系统。通过安装在无人机或单人设备上的高清摄像头实时采集图像,首先把图像转为视频信号,然后通过压缩处理将该视频信号传输到微波发射机的调制端,并通过微波发射机将该信号加载到载波上,经微波天线后定向辐射到耐张塔或无人机的微波接收机上,并通过对微波接收机解调出视频图像信号,将该信号送到硬盘录像机或监视器,实现了对输电线全天候无人监控。最后通过实例分析论证,证明了无人机输电线路巡线系统的可行性。

We designed a monitoring system of microwave wireless patrol due to the shortcomings of theheavy workload and difficult conditions existence in traditional manual inspection method. On transmissionlines all-weather unattended monitoring, is achieved by installing in UAV or single equipment HDcameras capture images in real time, and convert the image video signal after processing and transmissionto the microwave transmitter modulation compression end, microwave transmitter will be loaded onto thecarrier, by microwave directional antenna radiation to strain tower or drone of microwave receiver,microwave receiver a video image signal is fed into a hard disk recorder or monitor. Finally through theexample analysis, prove the feasibility of the UAV transmission line inspection system.
