Research on the Key Technology of 3 RF Wireless Bridge of Internet of Things for Transmission line

随着输电线路电压等级与输送容量的不断提升以及电网分布范围越来越广,实时、远程监控输电线路运行状态已成为输电线路安全运行的重点工作之一。通过低廉、可靠的无线专网可以有效减少租用公用数据网的通信费用,增加通信带宽,降低数据安全风险。将视频图像和传感数据实时传输到线路监测中心后,管理人员可以在线路监测中心实现对设备的远程实时监控,及时发现问题并进行处理,保障输电线路的安全稳定运行,并且可以通过在无人机和人工巡检终端搭载无线专网模块,实现无人机和人工巡检终端设备实时视频和数据的传输。实践证明,无线专网技术的应用可以使输电线路监测系统具有实时性、大数据量传输、高质量的视频图像以及更好的稳定性,以支持输电线路运行状态感知、预警、分析、评估等工作。

With the rise of voltage rating of power transmission lines and transmission capacity, the distribution of power grid is becoming wider and wider, so the transmission line real-time and remote monitoring becomes the key work of power production. Using the wireless private network to transmit monitoring data to the line monitoring center can reduce the communication cost of leased public data network, which can increase the communication bandwidth and reduce the data security risk. Then remote real-time monitoring, problem detecting and treatment can be realized, the safe and stable operation of transmission lines can be ensured. Through adding wireless module, real-time video and data transmission to the unmanned aerial vehicle and manual inspection terminal equipment can also be realized. Practice has proved that application of wireless private network technology in monitoring system has advantages of real-time large data transmission, high quality video image, more stability, it can better support the work of transmission line running state-aware, early warning, analysis, evaluation etc.
