摘　　要：为实现较小功率下太阳能智慧路灯的道路照明需求,该文设计基于窄带物联网的太阳能智慧路灯控制系统。通过系统中终端层的传感器单元,感知交通流量情况以及路灯运行状态等信息,利用通信层的LwM2M协议栈,将信息传送至平台层进行转换和解析处理后传送到应用层;应用层设定太阳智慧路灯的期望亮度,同时向终端层下达控制指令;终端层采用PID控制算法控制路灯的亮度效果。测试结果显示,该系统的网络传输能耗结果均低于3.5 kW·h,路灯运行总体耗电量均低于210 W·h,系统能够依据照亮路段的交通流量以及能见度情况合理控制路灯的亮度效果。In order to meet the road lighting requirements of solar smart street lamps with small power,a solar smart street lamp control system based on the narrowband Internet of Things is designed.Through the sensor unit in the terminal layer of the system,it can sense the traffic flow and the running status of street lights,and use the LwM2M protocol stack in the communication layer to transmit the information to the platform layer for conversion and analysis,and then send it to the application layer.The application layer sets the expected brightness of the sun smart street lamp,and sends control instructions to the terminal layer at the same time.The terminal layer uses PID control algorithm to control the brightness effect of street lamps.The test results show that the network transmission energy consumption of the system is lower than 3.5 kW·h,the overall power consumption of street lamp operation is lower than 210 W·h,the system can reasonably control the brightness effect of street lights according to the traffic flow and visibility of the illuminated road section.
