| 摘 要： | 随着地下采煤活动不断加大，越来越多的输电杆塔不可避免地被建设在煤矿沉陷区。目前，现有手段采用靠人力去进行定期检查一定会浪费大量的人力和物力，因而需开展对位于煤矿沉陷区的杆塔进行实时在线检测。基于NB-IoT和LoRa提出了一种新的算法——低功耗广域网（LPWAN）技术，提出了一种新型的输电杆塔倾斜监测系统，其中包含1个主节点和多个子节点，以适应地域广和远距离的需求信息监控。该系统通过LoRa多节点网络的数据传输，将杆塔的倾斜参数通过NB-IoT上传至在线实时监控系统。管理人员可以从后台得出监测数据并分析结果，及时对处于煤矿沉陷区的有故障的输电杆塔进行针对性的维护。

| Abstract: | As underground coal mining activities continue to increase，more and more transmission pole towers are inevitably being built in coal mine subsidence areas.At present，the use of existing means to rely on manpower to carry out regular inspections will definitely waste a lot of manpower and material resources.Therefore，real-time online inspection of pole towers located in the subsidence area of the coal mine is required.Based on NB-IoT and LoRa，a new algorithm is proposed，low-power wide area network （LPWAN） technology，and a new type of transmission pole tower tilt monitoring system is proposed，which contains a main node and multiple subnodes to adapt to the demand information monitoring of wide geographical and long-distance areas.The system transmits data through the LoRa multi-node network，and uploads the tilt parameters of the pole towers to the online real-time monitoring system through NB-IoT.Managers can derive monitoring data from the background and analyze the results and timely carry out targeted maintenance of faulty transmission pole towers in the coal mine subsidence area. |
