Research Of Building Intelligent LED Lighting Control System

With the development of social economy and science and technology， Energy lossproblems have become increasingly prominent. In china, intelligent lighting control in indoorpublic places, classroom and companies and enterprises, mostly adopt the traditional artificialmanagement style so that the lower efficiency of energy use. The kind of waste contrary to theconcept of saving energy. The saving energy has been related to major issues of sustainabledevelopment of social economy. Vigorous promotion and construction of intelligent buildinghas became the inevitable demand of the times.In the construction process of intelligentbuilding, the effect of intelligent lighting control system was significant. Application ofintelligent lighting include reasonable use of light source， lamps, electrical accessories, lightsource, optical devices etc. For example, make full use of natural light, the use of a variety ofenergy-saving control device, the use of intelligent lighting control systems.In this paper, the authors carefully analyzed the classification of feature natural light andsky models. By calculating the indoor illumination at some point, we have established a scalemodel of indoor illumination and reveal the indoor illumination relationship between each point.The DIALux illumination design software is used to emulate the model of lighting spaceenvironment. It can determine the distribution of lighting in space. By using MATLABcalculating software, the coefficients of related model can be determined. The roomillumination distribution model is designed based on BP artificial neuron networks. Thedesktop’s unified lighting optimization model is solved by using the genetic algorithm. Then theindoor intelligent lighting control system is created.In this paper, we designed the hardware and software of the building intelligent LEDlighting control system by ARM7. The design of lighting control system is divided into threeparts, which include upper machine and the master system and slave system. Upper machinesystem is developed by Visual C++.We have realize the centralized management of the buildinglighting. By embedded Systems, each module of intelligent lighting control system is designed.Then the device is selected on the basis.The whole control system applied CAN bus and I2C bus. CAN bus has realizedcommunication between the upper machine and lower machine. I2C bus is interface ofilluminance sensor.
