Application Research Of Intelligent Control Technique On Residential Lighting Control

"Intelligent" lighting technique has developed rapidly, and has become one important development direction of lighting technique as intelligent architecture rises. Aiming at the advantages and disadvantages of existing lighting control systems, it is very essential to develop a residence lighting smart control system for intelligent architecture's development and people's life quality improvement according to the control law determined by people's behavior pattern and residence luminous environment.The paper expatiates common human visual characteristics briefly, investigates common methods of easy home lighting design from the objective of lighting, residence illumination standard,the choice of light sources ,the choice of luminaires etc aspects, and illustrates rooms typical lighting design of easy home. When approaching any lighting design, the needs of visual information of the activities that will take place should be analyzed first so as to lighting system can provide a visual needed luminous environment simultaneously saving energy to rearize green lighting.The paper analyses the control principle of general several intelligent lighting control methods, analyses their advantages,disadvantages, applications, and the proceedings should be paid attention to in the applications; analyzes the characters and applicable scope of common several interior illumination calculation methods (the point method,the coefficient of utilization method,the unit capacity method), designs a lighting system for a living room; and brings forward to the system function of easy home lighting intelligent control system, studies design ways of its software and hardware. The system uses AT89C51 micro-controller, programs with assemble language, uses effective anti-jamming measures to ensure it operates reliably. Through debugging and test running, the system can realize system function designed completely.The system is test-running at a home in a intelligent residential district, arranges measured points of horizontal illumination in the living room, compares calculated values with measured values, and analyses the reasons of the difference between calculated values and measured values. Last the paper employs five-point method to calculate average illumination of major action area, and according to the average illumination determines the optimal setting way of dimming-ballasts, and by thealgorithm the system can realize intelligent dimming.As the people's living level rises, the home lighting intelligent control system will have a widely application future.
