Research And Design Of Intelligent Lighting Control System Based On STM32

Today,the continuous shortage of energy makes it become an significant problem for us human beings.In order to achieve long-term development,the Chinese government has put forward increasingly high requirements for reducing energy consumption,and the call for energy saving and emission reduction has been accepted by the public.The government even put the "implementation a comprehensive conservation strategy" into the Party’s 20 th National Congress report.Although electricity accounts for a quite small part of energy,it has a significant impact on daily life and economic development.To ensure the power demand,the application of electrical lighting control system is constantly expanded,and the control methods are also constantly updated.According to the analysis,the control effect of lighting plays a crucial role in the proportion of lighting energy consumption in building energy consumption.The problems of traditional lighting system including complicated wiring,high installation cost and difficult maintenance.On the one hand,the lights are not turned off timely after leaving,resulting in a serious waste of energy.On the other hand,with the development of various technologies,people put forward higher requirements for the energy consumption,intelligent regulation,convenient management,personalized operation and other aspects of intelligent lighting.Therefore,it is of great significance to discuss intelligent lighting control in meeting people’s need and energy saving and emission reduction.Based on the Changchun Science and Technology Plan project "Research on Key Technologies of Smart Campus Management Platform Based on Big Data",this paper carries out the research about intelligent lighting system,dividing the whole system into two parts: underlying hardware and upper software.The underlying hardware is composed of main control module,radar module,communication module and power module.Through the cooperation of detection node and radar sensor,the system detects the movement of vehicles and personnel.Subsequently,the STM32 gives instructions to adjust the duty cycle,so as to adjust the brightness of the garage lighting,thus realizing the low power consumption of the lighting system and "on-demand lighting".The upper software consists of upper computer and Android app for background control with two operating modes.In manual mode,the brightness of different lamps in different areas can be adjusted separately,and the Access database is used to record the working state of lamps timely.In addition,based on fuzzy control technology,this paper utilized expertise knowledge and field debugging experience developing the expected illuminance controller and lighting controller.Through the simulation effect comparison with the conventional PID control,this paper obtained the optimized intelligent control algorithm.Through the design and development of hardware circuit and software functions,the Android system client software and the whole system,including various functions and the control of lamp,are fully verified during the process of test.and the various functions of the system and the control of the lamp test.The adaptability test results show that the test effect is basically in line with expectations.This system successfully realizes intelligent lighting control and provides a useful reference for the subsequent promotion of intelligent lighting system.
