Abstract
In the traditional building automation systems, generally including integrated wiring, computer network, security, fire protection, closed circuit television monitoring system. However, in recent years, with the economic development and technological advancement of energy-saving lighting and a more scientific management, a higher demand, so that the lighting control system of the classroom with the energy-saving, convenient and intelligent functions, and can improve the work of the learning environment and achieve a variety of lighting effects, enhance the management level.
This single-chip microcomputer to control the core of classroom lighting control systems, related to the design of the system, the chip's working principle, the choice of components, production and other related issues. The control system is suitable for a variety of multi-media classrooms, the station waiting room, office and so on. It is mainly from the lighting controller, dynamic sensors, illumination sensors, composed of manual control equipment. Classroom lighting intelligent design goal is to highlight the intelligent lighting system, scientific management and energy conservation, the characteristics of saving operating expenses. AT89C2051 for the whole article to the control unit, simple structure and low cost.
Keywords：micro-control unit, lightening of the classroom, the intelligent control system
