Design And Realization Of Adaptive Wireless Smart Music-lighting System

Internet of Things and intelligent lighting technology developed rapidly.LED music lighting system based on intelligent lighting technology,with its convenient operation experience and gorgeous color effect,is becoming more and more popular with consumers.At present,LED music lighting system on the market mostly exists in the following problems: the system cannot adapt to the music;the lamps are unable to realize linkage;the operation is complex;and the equipment management process is tedious.Based on the wireless intelligent lighting system framework,this dissertation designs the intelligent gateway,full-color intelligent LED,and mobile phone client software,then realize the adaptive wireless smart music-lighting system.The system employ the wireless networking technology which is developed independently.The LED lamps are managed by the intelligent gateway.The wireless communication of the system has employ the communication protocol designed by ourselves,pairing each lamp and then control the whole lighting system.This dissertation proposes a new adaptive music lighting algorithm.Through the real-time analysis of music spectrum characteristics,this algorithm builds a model that matches the music and color,and adjusts the time delay dynamically.The new algorithm realizes the matching of light color and music,through matching the HSV color space and the basic acoustic characteristics of music.The algorithm realizes the coordination of music and light color transformation.The project proposed in the dissertation does not need to be prearranged,which can choose music freely.Compared to the current other music lights algorithm,the new algorithm made a great improvement in the sense of rhythm and the different styles of music on the adaptation.In this dissertation,the mobile client software in the intelligent LED system was designed of humanize.The APP,with an amicable user interface,was used easily and convenient.The control and use of the system is easy.User can choose the songs and the LED lamps in this client software.The design of the client software realized the "fool" operation,which reduced the using threshold of the users.In the client software,the playing songs and lights in the music lighting effect can be chosen by users,which satisfied the users' openness needs.This dissertation has conducted a comprehensive test for the wireless intelligent music lighting system,which contains the basic function and its stability,music rhythm performance and the realtime performance of the music light response.The test results indicate that all aspects of the system function and performance has achieved the desired design goals.The requirements of the adaptive wireless music lighting system was satisfied,with sound-light coordination and strong sense of rhythm.
