Development of NB-IoT Based Intelligent LED Light Pole Monitoring System

针对传统LED灯杆在远程监控、自动巡检、实时单灯调控、故障定位处理等方面存在的问题,本文提出基于窄带物联网(narrow band internet of things,NB-IoT)技术的智能LED灯杆监控系统的研制方案,采用STM32L151单片机作为主控芯片,控制多种传感器采集路灯信息,通过NB-IoT模块与核心网的连接,将采集到的路灯信息上传至OneNET云平台,并开发移动端应用程序(application,APP)和个人计算机(personal computer,PC)端监测界面以实现路灯故障信息的实时获取。实验结果显示:所研制的系统可以实时监测、控制路灯,快速、准确地确定故障路灯位置,实现单灯控制。

In order to solve the problems of traditional LED light pole in remote control-ling,automatic inspection,real-time single light regulation and control,and fault location recognition,an intelligent LED light pole monitoring system based on narrow band internet of things(NB-IoT)is proposed in this paper.In the system,STM32L151 micro controller unit(MCU)is adopted as the processor,together with multiple sensors to realize signal acquisition of street lamp.Through the connection between NB-IoT modules and core network,signals are collected and uploaded to OneNET cloud platform.And with a devel-oped mobile application(APP)and a personal computer(PC)monitoring interface,fault location information of street lamps can be obtained in real time.Experimental results show that the developed system can not only achieve real time monitoring and control of street lights,accurate positioning of faulty street lights,but also realize the individual control of street lights.
