高校教室智能灯光控制系统的设计

Design of intelligent lighting control system in university classroom

针对高校教室灯光用电浪费严重的问题,文章提出一种智能型的灯光控制系统。该系统采用STC89C51单片机作为核心控制器,利用红外、光照度传感器来采集环境参数,辅以时钟电路模块、存取电路模块、报警电路模块、按键模块、显示模块、灯光驱动模块实现了教室灯光能够根据室内人数、光照度强度、是否是上课时间等因素智能开启相应的灯光数,达到了节能的目的。

In view of the severe waste of lighting electricity of university classroom, this paper presents a intelligent control system. The system adopts the STC89C51 microcontroller as the core controller, using infrared-rays sensor, solar sensor to collect environmental parameters, supplemented by the clock circuit module, access circuit module, alarm circuit module, keys module, display module, light-driving module, and finally the classroom light can open the lights intelligently according to the number in the classroom, light intensity, whether it is classtime,, achieving the purpose of energy saving.
