The Design Of Light Control System Of Building

When the light bright enough , lamps still open in some school classrooms during the day. In response to this energy waste phenomenon, analyzing classroom lighting intelligent control principle and method,extending tthe whole teaching building classrooms lighting intelligent control , proposing a design concept integrating ARM9 control technology, Zigbee wireless communication technology and sensor technology in one school building intelligent optical control system and developping intelligent light control system's hardware devices and corresponding software.In whole building classroom intelligent optical control system, ARM9 main controller is control center of system,responsibling for regulateing system of working hours and working out standards of lamps lighting and closing, and orders from time to time. Main controller and a Zigbee wireless transceiver module through the serial cable connected, main controller orders through the Zigbee wireless module sent to a wireless transceiver features brightness control device, after brightness control device receives order ,detecting of lamps on or off state, collecting the natural brightness of the classroom, analysising and processing, etc. at last, completing the appropriate operation of the control room lighting to achieve energy-saving purposes.On the hardware realization is mainly designed to Zigbee wireless transceiver module and brightness Monitor Module, on the software realization is mainly to prepare the main controller in the control program, Zigbee wireless transceiver module functions, and brightness control Instrument performance function.This system is low cost, effective use the ARM and Zigbee wireless communication technology into classroom energy-saving and the system is easy to generalize. Wish this system is helpful to school light energy-saving, and contribute to national energy saving career.
