Research On Energy-saving Control System Of Intelligent Building Illumination

With increasingly development of science and technology at now,people’s life quality put forward higher request, and the comfort of life become preferred. At the same time, the energy consumption of at an unprecedented rate in almost dried up. Therefore, the concept of green,environmental protection, sustainable development is mentioned, it is deeply rooted in the hearts of the people.As an important energy production-lighting, its control system application is more and more widely, and its control measures are also changing. Comply with the demand of the development of intelligent buildings, healthy and comfortable green lighting is good for people’s physical and mental health. The intelligent building lighting becomes achieved the designed goal, the form of electric lighting and control strategies are to be considered to the sustainability and conservation of energy.The building lighting intelligent control as the core is descripted in this article,and it is to mainly study from the following several aspects:1. The overall design scheme of the control system the overall design scheme of the lighting control system is given according to the characteristics of the construction and function, and the user’s activity schedule. The requirements of green, environmental protection, intelligent are fulfilled firstly, and simple structure, flexibly wiring, conveniently setting up, low operation and maintenance management cost are strived to be mentioned. The core of the lighting control system is controlled by a microcomputer, it achieves the continuous sample of input signal then output voltage of the system is analyzed. At the same time its internal system setting and the optimal threshold voltage is compared and analyzed, if there are differences between, the open mediation system calculation module is used to need, then to achieve the optimal lighting of the output voltage.2. The hardware design of the control system:According to the overall design of the control system, complete the hardware circuit part of the unit circuit design and selection of components,including sampling driven design, infrared light driven design and relay control circuit, etc. This design uses the fuzzy PID control algorithm, using the algorithm to complete the input voltage and lighting voltage threshold set by the system, to achieve the number of the illumination lamps and lanterns and indoor appropriate to the purpose, in order to the brightness of the best effect.3. The software design of control system: according to the overall design of the control system and the function of the hardware circuit, follow the modular design requirements, firstly complete the overall design of software,and then according to the functional requirement unit module, to design of each function module, respectively, this design is good for the late test.4. The control algorithm of the control system design: according to the design function requirement of software and hardware, this paper adopts the fuzzy PID control algorithm, the algorithm of intelligent lighting control system control the input voltage, and Make the optimal lighting brightness,then the fuzzy PID control algorithm is compared with the traditional PID algorithm.
