Research On The Application Of LED Indoor Intelligent Lighting Based On WiFi

With the rapid development of modern science and technology,people are willing to pursue a higher standard on the quality of life.Lighting systems,as an important part of home life,have also received widespread attention.The traditional lighting system has complicated wiring and inconvenient control,which can no longer meet people’s lighting needs.The rapid development of WiFi and LED and the popularity of Android smart phones provide the technical foundation for the development of intelligent lighting systems.The intelligent lighting system has the advantages of energy saving and environmental protection,prolonging the life of the light source,improving the working environment,enriching the lighting effects,and facilitating maintenance and management.The control is convenient and the operation is simple,and it has been widely recognized by the market and the public.In this paper,a WiFi-based LED intelligent lighting control system is designed.The Wi Fi module works in the AP mode and connects the smart terminal to the wireless network.The user manages the data storage information through the intelligent terminal and interacts with the lighting system to process the data and the ultimate realization of intelligent lighting control.The paper first analyzes the research background and significance of the topic,briefly describes the current status of intelligent lighting development,and designs the overall architecture of the system by analyzing user requirements and functional requirements.After comparing the existing popular wireless connection methods,the intelligent lighting system decided to use the wireless communication protocol WiFi and introduced the Wi Fi network structure.Through the design principle of the WiFi module,the principle of the WiFi module,the communication method,the power-saving mechanism and the LED connection method,the hardware part of the system is described.The software part of the system mainly implements the design of the Android client,the construction of the Android software development platform,and the initial design of the AP mode.It focuses on the realization of different control functions of the LED lamp and the interaction between the terminal and the lamp,and writes its process.Figure andfunction code.Android light control system is based on the latest Android studio platform development,including login function module,single light control module,add light module,unified control module,reset account password module and different mode adjustment module design.The system involves the operation of the database SQLite,Dialog,List View,Button and Seekbar control settings,HTTP protocol request and callback;Acitivity and Service life cycle calls;system architecture using the MVC framework,so that data,view,controller height Decoupling to facilitate post-maintenance and secondary development.The network request framework uses the former Baidu framework Xutils,which integrates functions such as database operations,Http requests,and thread control.At the last stage,I have an overall test on the client software of Android system and the entire system.The various functions of the system and the control of the lights have been verified.I also had adaptive testing on the Android software system.And the test results were basically consistent with expectations.The intelligent lighting control system completes the LED intelligent lighting control based on Wi Fi,and it can give references for the following realization of the intelligent lighting system.
