Research On The Intelligent Control System Of Urban Street Lights Based On LoRa Communication

Urban municipal infrastructure includes roads,bridges,various underground pipelines and so on.Street lamps are also an important part,and the most intuitive part for the public.Intelligent energy-saving control and fine management are very important work contents for urban road lighting management and maintenance departments.An advanced intelligent control scheme for urban street lamps can help urban managers to play a vital role in energy conservation and emission reduction,and improve management capacity.At the same time,it also has great value in promoting the green low-carbon and sustainable development of urban road lighting.This paper is based on LoRa wireless communication technology,combined with the current Internet of Things and road lighting control technology,and according to the latest cloud computing applications,the research and design of intelligent control system is applicable to most of the small and medium-sized municipal roads.Firstly,based on the in-depth study of the status quo and background,the overall scheme of the control system is designed.And through in-depth analysis of the narrowband Internet of Things LoRa communication technology,select SX1278 based on LoRa modulation technology as the main communication chip.Based on the LoRa technical research,the intelligent control system of street lamp is designed in detail,including hardware design,embedded software design,communication protocol and automatic networking.Then,many advanced programming techniques(Microsoft.NET and SQL Server,etc.)are used to design the host workstation application software for the intelligent control and management system of street lamps.Finally,the function and stability of the system were tested and adjusted at the scene of municipal road.The experimental data prove that the system design specifications,user interface brief intuitive,communication and control functions accurate,meet the design requirements of the street lamp intelligent control system,possess the good commercial value.
