Design Of Building Intelligent Lighting System Based On Internet Of Things

With the development of science and technology,the human lifestyle is gradually becoming intelligent and diversified.Lighting system is an important part of public buildings.How to save energy and improve lighting utilization has become a hot issue in the construction of modern public buildings.Traditional lighting systems have been unable to meet the lighting requirements of public places due to their single function and cumbersome lines.But the development of Internet of Things technology and the popularity of intelligent terminals have provided technical support for intelligent lighting systems.This article combines the structure of current public buildings with the analysis of traditional lighting systems and designs a building lighting system based on the Internet of Things.The intelligent lighting system of the building designed in this article consists of two parts and the LED lamp group and the cloud server.The LED lamp group adopts STM32F103C8T6 MCU as the core processing unit.And it is controlled by various sensors and LED driver chips.It realizes the basic lighting functions of the office,elevator room,corridor and other environments.The cloud server uses WiFi technology for Internet communication.And the ESP8266 chip creates a TCP connection with the cloud server.Each area uses microcomputer to process LED switch information,fault detection,and battery voltage data.And the microcontroller sends it to the server for background storage.The user can view the information of each LED group through the smart terminal device and can also send a reverse control command to the group.Finally,this article designs the hardware circuit and software system,and completes the design of intelligent lighting system.And this article tests the system's information transmission,LED switch and basic lighting of the lamp group.The article is to design the basic functions of the lighting group in different lighting environments.It combines the hardware platform and the Internet through WiFi technology in the building intelligent lighting system.The whole system adopts the new IoT architecture of single chip microcomputer + wireless communication technology + cloud server platform + mobile intelligent terminal.Finally,the system achieves unified management of public building lighting.
