基于LoRa通信的可视化城市照明系统设计

Design of Visualized Urban Lighting System Based on LoRa Communication

城市路灯照明系统是现代化城市的重要组成部分,为路灯设计可视化的智能监控平台,实现对路灯实时地监控,可保证其安全性及获得大的能效比。提出了基于LoRa通信的城市路灯监测和控制方案,该系统由远程监控中心、LoRa网关和路灯终端组成,并通过LoRa与4G网络相结合的方式实现远距离通信并实现联网数据传输。基于MQTT协议的阿里云物联网平台,实现照明终端状态显示在阿里云平台并储存信息;通过ARM开发的嵌入式控制系统实现了对路灯信息的上传和指令的下发,并对各个路灯终端进行实时控制。系统实测结果表明,该系统可实现对路灯信息的实时采集、上报,并及时响应上位机发出的控制指令,大大降低了照明功耗及人工巡查的成本。

The urban street lighting system is an important part of modern city.A visual intelligent monitoring platform is designed for street lamps to realize real-time monitoring,which can ensure its security and obtain high energy efficiency ratio.This paper presents a monitoring and control scheme of urban street lamp based on LoRa communication.The system is composed of a remote monitoring center,a LoRa gateway and a street lamp terminal.It uses a combination of LoRa and 4G network to achieve long-distance communication and network data transmission.Introduce the Alibaba Cloud Internet of Things platform based on the mqtt protocol to realize lighting terminal status display on alicloud platform and store information;use ARM to develop an embedded control system to realize the upload of street lamp information and the issuance of instructions,and to each street lamp terminal Carry out real-time control.The actual measurement results of the system prove that the street lamp terminal responds to the commands issued by the host computer,collects and reports street lamp information,and greatly reduces the lighting power consumption as well as the cost of manual inspections.
