基于STM32的路灯智能监测控制系统

Intelligent Monitoring and Control System of Street Lamp Based on STM32

目前,国内的路灯设备基本上处于人工监控的状态,因此,需要大量的人力资源进行维护和维修。针对以上现状,设计了一种基于STM32的路灯智能监测控制系统,将物联网技术引入到路灯设备之中,实现路灯设备上的实时故障监测与智能控制。系统以STM32F103ZET6单片机作为MCU,通过RS485总线实现光照强度传感器和PM2.5传感器的信号采集,用固态继电器控制路灯供电电路的通断,利用电流互感器实时监测路灯供电电路的电流状态,并通过4G传输方式进行路灯下位机端与上位机端的信息交互。该系统能够实现环境数据实时读取、根据当前环境自动开关灯控制、远程手动开关灯控制和故障监测报警等功能。经试验验证,系统稳定可靠,采集数据准确,可以实现路灯系统的智能化控制。

At present,the domestic street lamp equipment is basically in the state of manual monitoring,so a large number of human resources are needed for maintenance and repair. In view of the above situation,we design an intelligent street lamp monitoring and control system based on STM32 and introduce the Internet of things technology into the street lamp equipment to realize the real-time fault monitoring and intelligent control on the street lamp equipment. With STM32 F103 ZET6 single chip microcomputer as MCU,the system realizes the signal acquisition of light intensity sensor and PM2.5 sensor through RS485 bus,uses solid-state relay to control the on-off of street lamp power supply circuit and current transformer to monitor the current status of street lamp power supply circuit in real time,and carries out the information interaction between the lower computer end of street lamp and the upper computer end through 4 G transmission mode. The system can realize real-time reading of environmental data,automatic on-off light control according to the current environment,remote manual on-off light control and fault monitoring and alarm. The test results show that the system is stable and reliable with accurate data collection,which can realize intelligent control of street lamp system.
