摘要
长距离输电时人工巡检十分困难,借助物联网技术实现传感器大规模协同工作,建设信息通信网络,可大幅度提升电网设备的监测水平。LoRa作为一种远距离低功耗传输技术,抗干扰能力强、成本低,适用于输变电线路监测。通过试验测试LoRa系统的传输特性,验证了将其应用在输变电工程中的可行性。
Manual inspection is difficult for long-distance transmission.With the help of Internet of things technology,large-scale cooperative work of sensors and the construction of information communication network can greatly improve the monitoring level of power grid equipment.As a long-distance low-power transmission technology,LoRa has strong anti-interference ability and low cost.It is suitable for power transmission and transformation line monitoring.The transmission characteristics of LoRa system are tested,and the feasibility of its application in power transmission and transformation project is verified.
