Design of Classroom Intelligent Lighting Control System Based on Single Chip
Abstract: The thesis analyzes the principle and method of the classroom intelligent control, and proposes the concept of classroom intelligent lighting control system based on single-chip, and on the foundation, it develops hardware and software of the intelligent control system. The control device of system adopts AT89S51 single-chip to the main body parts, according to the reasonable light conditions in the classroom, the system completes intelligent control of the classroom lighting circuit by the recognition and intelligent judgment of the human body signals, the existence of environmental light signals and clock signals, in order to avoid much profligacy of the classroom. The software of Single-chip adopts the C language and modular design, and adopts Proteus software to simulate. The results show that it can meet the requirements of university classroom lighting control at a great extent, in order to achieve the purpose of saving energy.
