Design of Intelligent Controller for classroom Lighting based on single Chip Microcomputer
Abstract
This study of intelligent control classroom lamplight, analyzes the current situation of the development of the classroom light of intelligent control principle and method, is proposed based on single-chip microcomputer intelligent control of the classroom lamplight design. This system to AT89C52 single chip computer as control device of intelligent parts, adopts heat release infrared sensor detects the release of human existence and adopts photoconductive resistance constitutes circuit testing environment light intensity.According to the classroom light conditions and the measured the signal of human body system and ambient light, the system can make reasonable and intelligent judgment and then controls thework of classroom lighting circuit.It is a effectiveway to avoid the classroom ofwaste electricity. Smallvolume, convenient control, high reliability, high specificity and price reasonable make this system satisfy the advantages of large, secondary technical schools classroom light control requirements and greatly reach energy-saving purpose.
