Research On LED Intelligent Lighting Based On Home Scene

Lighting is one of the themes of people’s eternal life.As early as the beginning of the 21st century,the industry has put forward the concept of intelligent lighting,hoping to use computer and artificial intelligence technology to enhance the lighting project energy efficiency,comfort,efficiency and security.However,due to the long market maturity cycle,the unperfect information infrastructure,unperfect artificial intelligence maturity and many other reasons,home intelligent lighting system is still in the promotion stage.In recent years,with the improvement of the comfort of the living environment,the gradual improvement of the Internet infrastructure,the progress of computer science,the solidification of LED solid-state lighting and the rise of the domestic smart home market,home intelligent lighting market once again usher in more possibility.However,due to the complexity,variability and uniqueness of the home environment,there is still room for the improvement of the theoretical and practical degree of the home lighting system.Therefore,based on the existing theory and technology,this paper studies a new form LED intelligent lighting system based on home scene.In this paper,the intelligent lighting theory is analyzed in detail,and the lighting scheme is proposed to identify the home scene by using the scene model and the speech recognition method.The program can quickly determine the required lighting scene from the indoor environment,the current time and voice commands,and is simple and reliable,without prior training and high flexibility.Then,based on this program to build ZigBee wireless network and research and production of seven different roles ZigBee hardware nodes,including network coordinator,switch LED lamps,dimmable LED lamps,temperature,illumination,body sensors,voice recognition sensors,To achieve all the lamps and sensors of the wireless Internet and remote control.Then,this paper overcomes the technical problems of sensor data processing and speech recognition.The intelligent lighting control software is implemented on ARM Cortex-A53 embedded system with Node.js,and the illumination model of L-type living room Initialize the system,which contains the living room lights,reading,cinema,warm,full light,turn off,night light a total of 7 scenes.The average delay of manually controlling the lamps is 107.71ms,and the average delay of the automatic switching of the scene is 731ms,which achieves a better user experience.It can be used to control the lighting of the household.Finally,this article also studied the production of web-based client,allowing users to use the computer and mobile phone switch lights,switch home lighting scene,custom lighting system.Measured that the system can support up to 20 clients at the same time control,and to ensure that the state between the various client synchronization.In this paper,through the actual operation of a system to achieve the home scene under the lighting of the wireless manual control and lighting scene intelligent switch to verify the availability of this intelligent lighting system.
