电力线路无线温度监测系统设计
Design of Wireless Temperature Monitoring System for Power Line

针对电力线路温度监测特殊需求，设计了一种基于STM32L0系列单片机的低功耗电力线路无线温度监测系统。基于短距离蓝牙通讯，实现了传感器终端和杆塔接收节点的通讯，使用4G通讯实现安装在杆塔上的中继器和后台服务器的通讯。监控后台采用B/S模式，结合Ajax技术，实现了基于Web的实时通讯。采用休眠技术和休眠断电方法，实现了小容量光伏电池和蓄电池的长期供电。系统投入实际现场应用，具有良好的实时性、稳定性、低功耗性，有很好的工程应用价值。
For the special requirements of power line temperature monitoring, a low-power power line wireless temperature monitoring system based on STM32L0 series is designed. Based on the short-dis- tance Bluetooth communication, the communication between sensor terminal and the tower reception nodes are realized, and the communication between the repeater and the background server is realized based on 4G communication. The background monitoring software adopts B/S mode and is combined with ajax technology to realize Web-based real-time communication. Using sleeping technology and power-off control method, the long-term power supply of small-capacity photovoltaic cells and batteries is realized. The system is put into the actual field application, which has good real-time, stability, low power consumption, and a good engineering application value.
