基于LoRa和NB IoT的分布式光伏电站监测系统设计

Design of distributed photovoltaic power station monitoring system based on LoRa and NB IoT

针对分布式光伏电站分布广泛、缺乏集中化管理等问题,设计了一种基于LoRa和NB IoT的分布式光伏电站监测系统。该系统通过无线终端节点采集分布式光伏电站的温湿度、光照强度、电压、电流等数据,再通过LoRa无线通信技术进行组网,将采集的数据汇聚到网关后依靠NB IoT无线技术上传至OneNET云平台,用户端调取云平台数据对分布式光伏电站进行监测。实验结果表明,该系统成本低、组网灵活,能够长时间稳定运行,可满足电站监测需求。

To address problems such as wide distribution and lack of centralized management of distributed photovoltaic power stations,a monitoring system for distributed photovoltaic power station based on LoRa and NB IoT is designed.The system collects temperature,humidity,light intensity,voltage,current and other data of distributed photovoltaic power station through wireless terminal nodes,and then carries out networking through LoRa wireless communication technology.Once the collected data is aggregated at the gateway,it is uploaded to the OneNET cloud platform using NB IoT wireless technology allowing the user side to retrieve cloud platform data to monitor the distributed photovoltaic power plants.The experiment results show that the system with stable operation for extended periods is cost-effective and offers flexible networking,which can satisfy the monitoring requirements of power stations.
