Research On DALI Protocol Based Intelligent Lighting System Design For Buildings

Because of the progress of the national economy and the improvement of the quality of life,lighting control has received more attention than ever before.In addition,due to the severity of the energy crisis,the country is strongly promoting energy conservation and emission reduction.Based on this,we can simultaneously meet the two requirements of building intelligent lighting system to attract public attention.However,there are still a lot of energy saving in the domestic intelligent lighting system,especially in the daytime,the utilization of natural light is still insufficient.This paper discusses the intelligent lighting system based on DALI protocol.The main research work flow and the internal core program,and based on the actual engineering design,design based on DALI.In addition,this paper uses the DIALux software and artificial neural network to establish the model of the indoor illumination distribution,in order to make full use of the principle of daylight natural light to study the system's dimming control strategy,using genetic algorithm to achieve the purpose of adaptive intelligent control of indoor desktop surface illumination,and finally use the program to achieve the optimal balance of desktop lighting.In the end of this paper,the power data of the intelligent lighting system is used in the condition of different weather conditions.By comparing the power data with other different lighting control modes,the intelligent lighting system has been found to realize the maximum energy saving of the natural light,which can provide a theoretical basis for the promotion of the light control system based on DALI protocol.
