Multi-light Linkage Music Lighting System Based On Spectrum Analysis

With the development of the Internet of Things and intelligent lighting technology,the music lighting system is welcomed by the majority of users because of its easy installation and brilliant lighting effects.However,there are the following disadvantages in the main music lighting products currently on the market:(1)The system needs to be manually arranged in advance,and there is not a very good rhythm for music input randomly.(2)Mostly single product-based,can not form a linkage group more light,limiting the effect of music lighting.(3)User control software features a single,lack of beauty UI interface,user experience difference.First of all,this paper proposes music lighting algorithm based on spectrum analysis.Through real-time extraction of music spectrum parameters,the HSV color model matching the spectral parameters is established and the delay parameters are dynamically adjusted.Algorithm music lighting system rhythm is a good thing,without prior arrangement,the music entered randomly.Based on this work,a wavelet transform denoting algorithm is designed to further suppress the influence of noise.Extracting music rhythm points through peak detection,establishing a color value-tone difference model to extract hues greatly improves the single issue of lighting color transitions in smooth music.The experimental results show that the proposed music lighting algorithm based on spectrum analysis proposed in this paper can provide a good rhythm to random input music.In this paper,independent research and development of wireless networking technology,put forward the gateway automatically network,node network design,multiple devices can automatically form a network,wireless network devices through the gateway and client seamless convergence to achieve the goal of unified management.The equipment used in the system is easy to install,easy to add,delete,and easy to operate.Based on wireless networking technology,this paper proposes a multi-light linkage mechanism to support uneasy,multicast,broadcast three ways to control the lighting.Experimental results show that the multi-light linkage mechanism designed in this paper has good real-time performance,obvious lighting linkage effect and excellent performance.This article designs music lighting control software based on Android platform,and puts forward an event processing framework based on double-cache mechanism to relieve the pressure on the system network and the performance consumption of Android system.A mechanism to judge the client network type quickly by sending UDP broadcast is designed.A method for real-time monitoring the client network status is proposed to realize the automatic switch between client and gateway working mode.Client control software interface beautiful,feature-rich,users through the "fool-type operation" can achieve the control of the lamp.The test results show that all aspects of client software performance meet the expected requirements to meet the sound and light coordination of music lighting system requirements.
