In traditional Building Automation Systems, Generally include cabling, puter work, Safety precautions, Fire Prevention , TV monitor and other subsystems. But in recent years, With economic development and the advancement of technology, people lighting energy conservation and scientific management of higher demand, making the field of intelligent lighting control is being increasingly important. Power for the university campus in the proportion of low power and cooling equipment, and relatively high lighting situations, the design energysaving control system for teachers. The design includes Smart Controller for the machine and application configuration MCGS for PC monitoring program, both through the popular Modbus protocol munications. The former applies a certain logic algorithms, illumination detection and infrared detection bined by active and passive detection, to develop energysaving lighting control system of classroom. We can benefit from two aspects from it. One aspect is that it can automatically turn off lights, if there is no people or there is sufficient light in classroom . Another aspect is that if someone is ing and the light is insufficient , it can automatically turn on the lights to achieve energy saving. The latter is used for the centralized management of the read and write, display and control of the next bit plane parameter, so as to achieve a plete and reliable lighting control system for distributed. Key words: Classroom lighting。 modbus protocol； Energy Saving Control； Pyroelectric effect 內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計說明書（畢業(yè)論文） III 目 錄 摘 要 ...........................................................................................................................................I Abstract ......................................................................................................................................
