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。
Aiming at the disadvantages of traditional manual inspection methods, such as heavy workload and difficult conditions, a microwave wireless inspection system is designed. Through the installation of unmanned aerial vehicles or single-equipment high-definition camera real-time acquisition of images, the first image into a video signal, and then compressed by the video signal transmitted to the modulation side of the microwave transmitter, the microwave transmitter to the The signal is loaded onto the carrier, and then directed to the microwave receiver which is resistant to the tension tower or the UAV by the microwave antenna. The video signal is demodulated by the microwave receiver to send the signal to the hard disk video recorder or the monitor All-weather transmission line no one monitoring. Finally, the case analysis proves that the UAV transmission line inspection system is feasible.
