摘要
为满足现代化校园照明控制的要求及需要,设计了基于AT89系列微控制器的智能教学灯光控制系统。智能控制器通过光电传感器测得周围环境的照度,与设定值比较,调节光源的输出,使光照度达到合适的水平。通过红外传感器判断教室内部的人数,根据光线等级和教室人数情况,及模糊控制计算,系统给出相应的开关动作来控制教室的照明,实现以指令的方式对教学楼照明的总体控制。
The design of an intellectual lighting control system for teaching purpose based on AT89 microcontroller series is presented.The intellectual controller can measure the surrounding illumination with photosensors and compare the illumination with the set values to regulate the light source output,and an illumination up to an appropriate level can thus be obtained.And through infrared sensors,the number of people in the classroom can be evaluated.Through fuzzy control calculations,the system can provide corre...
