Design And Implementation Of Intelligent Street Lamp Control System Based On LoRa

Street lamps are an important part of urban infrastructure construction.How to achieve scientific and intelligent management while completing the basic lighting task has been widely discussed in the industry.The traditional street lamp control method has many problems,such as resource waste and low management efficiency.On the one hand,street lamps continue to work at full capacity during periods and areas with few personnel activities,which wastes a lot of power resources.On the other hand,the traditional street lamp control system does not have wireless communication and intelligent control functions,and requires manual control,management and maintenance,resulting in low work efficiency and chaotic management mode.In this paper,a refined and intelligent street lamp control system is proposed,abandoning the rough street lamp management mode.The system is composed of a field system and a remote control platform.The field system includes a centralized controller part,single lamp control part,sensor part,and wireless transmission part.The remote control platform is mainly responsible for the management and control of the field system,including fault information processing,street lamp monitoring and other functions.Onsite system combining embedded system technology and wireless communication technology,based on STM32 centralized controller is designed,adopting Lo Ra rate adaptive algorithm is proposed in this paper realizes the centralized controller and single lamp controller between a pair of wireless communication,more effectively improving the efficiency of wireless communication,making the system work in complex scenarios still keeping a steady communication.Modbus bus and communication protocol are designed.The centralized controller collects the environmental parameter information of each sensor module through Modbus bus,and intelligently adjusts the brightness of street lamps according to the environmental parameters combined with the comprehensive control strategy based on fuzzy control proposed in this paper,achieving the goal of intelligent and energy-saving lighting.The remote control platform adopts the mainstream programming technology(Python,Maria DB,Nginx),and communicates with the centralized controller through Ethernet to realize the remote monitoring and control of the street lamp system.Finally,set up the test environment for the intelligent street light control system for single hardware test platform,the remote control,street lamp control strategy for the test,the test results show that the system in such aspects as reliability,energy saving and intelligent control has strong advantages,can be applied to all kinds of lighting environment,has a good application prospect and market potential.
