Research Of Teaching Building Intelligent Lighting Control System

According to the international energy shortage and the waste of college teaching building lighting, it is necessary to design a kind of applied in the teaching building intelligent lighting control system. The CAN bus has high reliability and good real-time performance, cost reasonable and perfect functions. It is a common field bus technology, that be widely used in various fields. As an underlayer oriented serial communication, LIN bus is low-cost. It is an effective complement for CAN bus. CAN/LIN mix network can make some cost down and enhance communication efficiency. It has meaning to the research of teaching building intelligent lighting control system.Firstly, the phenomenon of energy waste at home or abroad and several common Fieldbus Technology are analyzed. A building intelligent lighting control system is proposed, which is based on CAN/LIN bus.Secondly, the paper introduces the function of illuminance module and infrared detection module, and determines the design of relevant circuit. DIALux software for classroom illumination conditions are used to simulated, so as to determine the installation position of inspection module.Thirdly, as the most important part of this thesis, the design of bus interface circuit is researched. Through the transceivers for CAN bus and LIN bus, the bus interface circuit is determined and analyzed. Lastly, according to bus agreement, software components of the control bus were studied. Control program written using C language to complete the communication between different bus, to achieve the teaching of intelligent building lighting control system.According to requirements of the subject, the theory and implementation method for teaching building intelligent lighting control system is completed, to achieve communication between the control bus.
