摘要
为了提高路灯照明灯智能化管理能力,提升精细化控制水平,实现高效的节能目的,设计了一种基于PID亮度调节的智能路灯系统。该系统以STM32作为主控单元,采用BH1750亮度传感器进行亮度检测,通过PT4115驱动芯片实现LED的恒流与亮度控制,使用nRF24L01实现无线数据通讯和控制。设计了系统的控制软件,使用不同的参数测试了滤波器与亮度控制器的效果。试验结果表明,所设计的系统能够较好地实现设计目标,具有实用意义。
In order to improve the intelligent management capability of street light illumination,enhance the level of fine control,and achieve the purpose of efficient energy saving,an intelligent street lamp system based on PID brightness adjustment is designed in this paper.The system is based on the STM32 as the main control unit and uses the BH1750 brightness sensor for brightness detection.PT4115 driver chip for constant current and brightness control of LEDs,nRF24L01 for wireless data communication and control.The control software design of the system is introduced,and the effect of the filter and brightness controller is tested using different parameters.The experimental results show that the system can better achieve the design objectives and has practical significance.
