Abstract
With people's living standards improve and the development of light, people demand more and more lighting, require the use of light create a harmonious atmosphere and comfortable environment and to create one kind of moving effect and operation of the simple. Most colleges and universities in China are higher than the standard classroom illumination, combined with human waste caused by unnecessary expenditure, to save resources and contribution to society and to save many expenses to consider college, university building intelligent lighting management reform momentum must be carried out, the classroom lighting intelligent control system development for energy-saving lights in public classrooms is very important practical significance.
This topic is mainly for university building lighting energy waste management in the phenomenon, the design of the teaching building intelligent lighting system, intelligent control to achieve energy saving targets through.
The design is focused on classroom monitoring system, based on current university teaching building electrical waste to AT89C52 core CPU design classroom controller (which include light sensors, infrared sensor). Effectively in the classroom electrical equipment, the number of students and classrooms to monitor the light intensity, light intensity and by whether someone in the judge room automatically switch lights to save energy.
