公共场所照明节电智能控制系统设计

该系统在传统的热释电人体红外开关的基础上,加入以电机为主的机械部分,周期性带动热释电传感器移动,使静止的人体对其产生相对运动,因而能检测到静止的人.另外还加入了以Atmega8单片机为核心的控制系统,在软件的配合下,系统智能化程度高,能正确判断周围环境并进行动作.因此能用于教室、办公室等对照明质量要求较高的场合,实现有...

Design of an Intelligent Control System for Energy-saving Public Lighting

On the basis of the traditional human body phyoelectric infrared switch,motor-based mechanical parts are added to drive the pyroelectic sensor moving cyclically,so that the pyroelectric sensor can scan human body even they keep still for a long time.An Atmega8 microcomputer-based controller is also added,and in cooperation with the software,the intelligent system is able to judge the environment and make a rapid action correctly.The system can be used in classrooms,offices and other place where high quality lighting is required.To save energy,the system controls the lights on where there are people,and lights off elsewhere.In addition,installation of the system requires only minor changes to the original lines.
