Research On Intelligent Lighting Control System Of College Classroom Based On Zigbee

With the development of science and technology, especially the rapid maturation of Internet of things technology and the fully understanding and desire of people for low carbon, green environment, the traditional lighting is transforming to the intelligent control of illumination quickly. College exists the phenomenon of large lighting quantity and high energy consumption because of its unique function and needs. On the initiative of "ten two five"construction plan, building a conservation-minded campus and transforming it to intelligent and economic is the urgent task of current situation.This paper designed a fuzzy control system of intelligent lighting of college classroom based on Zigbee technology to realize intelligent control of lighting. Using illumination sensor, vibration sensor and infrared sensor, the solution automatically collected information of classroom illumination and use state, number and location of people and so on, and applied improved adaptive FMRAS (Fuzzy Model Reference Learning Control) control algorithm to do fusion analysis, generate PWM code automatically and control lighting intelligently. Under the condition of satisfying the needs of national standard of illumination,this paper achieved the purpose of energy saving. And considering the principle of friendly human-computer interaction and convenient management, designed LCD display and monitoring management system to facilitate monitor and examination for administrator, teachers and students.First of all, mainly relying on the selection of ARM9host controller and peripheral hardware module and the circuit design of wireless sensor network terminal node module, introduced building scheme of hardware platform of system; Secondly, introduced the research and improvement of adaptive FMRAS control algorithm according to control strategy of lighting. On the basic of operation experience of skilled staff, summary knowledge of experts and experience parameter, this paper mainly discussed the principle of improved adaptive FMRAS control algorithm and the process of matlab simulation. Finally, introduced the development and debugging process of software system. Mainly include:the build of ARM9embedded software system such as U-boot transplantation, Linux kernel, production of root file system and so on, development of application software of wireless sensor network protocol stack and the node.,and the software program of LCD and PC monitoring interface structures.It is proven that the intelligent lighting fuzzy control system of collage classroom which was based on Zigbee technology could not only regulate the output of lamp illumination automatically and stably according to light environment but also applied to the environment of collage because of its simple structure and easy reality. It achieved the purpose of energy saving on the basic of guaranteeing the stability of Intensity of illumination.
