为了解决现代城市智慧照明线路用电设备日益复杂造成的照明能耗监测难题,基于LoRa物联网技术设计城市道路照明能耗与窃电监测系统.系统是由具备LoRa无线通信功能的集中控制器、LED照明灯具和其他用电设备组成的LoRa无线通信网络;集中控制器为系统主机,LED照明灯具和其他用电设备为监控节点.提出了一种两步无线通信、分时同步采集所有监测节点电力数据,由集中控制器实现照明线路照明功率与能耗计算,判别窃电行为的实时照明能耗与窃电监测策略.介绍了集中控制器的硬件模块设计,详细给出了策略的软件实现方法,包括集中控制器程序设计和LED灯具驱动电源程序修改.照明能耗与窃电监测系统测试平台的实验结果验证了系统能有效实现无线照明能耗同步采集与窃电监测功能,可更好地满足城市路灯智能化管控的要求.
To solve the lighting energy consumption monitoring problem caused by the increasingly complex electrical equipment of modern urban smart lighting lines,the system of urban road lighting energy consumption and power theft monitoring is designed based on LoRa Internet of Things technology.The system consists of a LoRa wireless communication network of centralized controllers,LED lighting fixtures,and other electrical equipment with LoRa wireless communication capabilities.The central controller is the system host.And LED lighting and other electrical equipment are the monitoring nodes.A real-time lighting energy consumption and power theft monitoring strategy of two-step wireless communication,time-sharing,and synchronous collection of power data of all monitoring nodes are proposed,where the lighting power and energy consumption of lighting lines are calculated by the centralized controller.The hardware module design of the centralized controller is introduced,and the software realization methods of the strategy are given in detail,including the program design of the centralized controller and the modification of the power program of the LED lamp driver.The experimental results of the lighting energy consumption and power theft monitoring system test platform verify that the system can effectively achieve wireless lighting energy consumption synchronous collection and power theft monitoring functions,which can better meet the requirements of intelligent control of urban street lights.
