摘　　要：针对我国目前路灯覆盖面积大,管理手段落后,无法根据实际需要进行远程控制开关灯时间、无法监测各路灯的运行状况等问题,设计一种基于窄带物联网路灯控制系统方案,实现对路灯按需控制、及时了解各路灯的耗能情况,并综合现场的人流量情况,实现精确控制,最终达到节约能源的目的;该终端采用意法半导体STM32芯片为微控制核心、以窄带物联网技术为传输方式、以天翼云平台为支撑的系统总体框架,阐述了系统硬件、软件设计思路,制定了路灯控制器、天翼云平台、后台服务系统之间的通信协议,实现了路灯控制器、云平台、后台服务终端三者之间的信息交互;测试及应用结果表明,在无线网络基站已覆盖场所,通信成功率达99%以上,数据通信响应时间小于1 s,控制系统稳定可靠,为将来路灯节能控制和管理提供了有利的保障。Aiming at the problems of large coverage area of street lamps,backward management means,inability to remotely control the switching time according to the actual needs,inability to monitor the operation of each street lamp and so on,a scheme of street lamp control system based on narrowband Internet of things is designed to control the street lamps on demand,timely understand the energy consumption of each street lamp,and integrate the on-site human flow situation to achieve accuracy control,and finally achieve the purpose of energy conservation.The terminal uses STM32 chip as micro control core,narrowband Internet of things technology as transmission mode and Tianyi cloud platform as support system framework.It describes the design ideas of hardware and software of the system,formulates the communication protocol among street lamp controller,Tianyi cloud platform and background service system,and realizes information interaction among street lamp controller,cloud platform and background service terminal.The test and application results show that the success rate of communication is more than 99%,the response time of data communication is less than 1 s,and the control system is stable and reliable,which provides a favorable guarantee for energy-saving control and management of street lamps in the future.
