Abstract
Present in all office buildings，office and school building ，libraries and other public places， because of the use of the crowd is not fixed，often there is the phenomenon that we ignore the lights ，thus causing unnecessary waste of energy and economic losses．In addition，a variety of lighting fixtures are used with a certain time frame，if continue to use in the sunny conditions，it will certainly shorten the lamp life．In order to solve the above problems，this article designs a real-time intelligent control of indoor lighting management system based on a microcontroller．This program uses photosensitive resistors，infrared sensors and microcontroller technology and designs sensor interface circuits，A／D conversion circuit，lighting control circuit，achieves real-time monitoring of indoor lighting and judging if there is somebody in the room．AT89S52 MCU controls room by the light switch status，using assembly language design A／D conversion．It realizes real-time control of indoor lighting，and meets the convenience and energy savings．
In this article, it introduces the systematic development background, the significance and especially the process of the hardware design and the software design .In the hardware aspect, this article elaborates the part, the module, the system one by one, especially the core of the system AT89S52,and uses the PROTEL . Software to the schematic diagram and the electric circuit board manufacture. In the software aspect with the present stage quite popular monolithic integrated circuit C language programming,. Finally it was the software and hardware debugging, in which introduced the in stations of the stations of monolithic integrated circuit simulation software WAVE6000 use.
