Intelligent Lighting Control System Based On DALI And Integrated Network

in recent years,as the development of Internet of Things and the improvement of the quality of life,the concept of Smart Home based on Internet of Things have been deeply rooted among the people and will become a hot spot in the future development of Internet of Things,especially the intelligent lighting control system with the WiFi technology will show extraordinary talents in Smart Home.This article aim at the intelligent lighting control system on the market exists the problems such as the complex layout of circuitry,the bad changeability,inherent high cost,based on DALI agreement of intelligent lighting and the technology of WiFi network communication,take full advantage of electronic technique,communication technology and computer network technology,connecting different kinds of lighting appliances of the building,with the intelligent lighting control system which combined with wire and wireless,realizing the functions of energy-efficient,easy managing,diversified controlling,costing reducing,green lighting and so on.This article firstly analyze the development history and existing conditions of intelligent lighting,telling the feature and functions of the system,at the same time,expounding the basic components,theory and the application of DALI agreement,pointing out the advantages of DALI compared with analog dimming technology and bussing technique.The system this article designed contained upper computer module,master control module,wifi module,drive module,slave module,which can make users using mobile phone or computer,by the way of wire or wireless,making the master module according to the DALI agreement control the slave module so that users can control the lights in the building by groups or alone,at the same time,users can receive the massages of the lights.considering the practical applicability practicability and reliablity of the system,this paper applies the compromise algorithm to the address distribution of the lampand realizes the automatic address distribution of the lamp.At the same time,considering the coverage of the whole control system,adding the WiFi network technology,and the control scope of the lamp is expanded.Considering the problem of bus communication conflict,the bus working state query and waiting mechanism is designed in the software,which makes the system work more orderly.In hardware design,a more reliable and less power-consuming hardware design is adopted.
