公共场所照明自动控制系统设计

摘要：本研究针对教室灯光的控制方法，尤其是教室灯光的智能控制方面的发展现状，分析了教室灯光智能控制的原理和实现方法，提出了基于AT89S51单片机的教室灯光智能控制系统的设计思路，并在此基础上开发了智能控制系统的硬件装置和相应的软件。

该系统以AT89S51单片机作为控制装置的智能部件，采用ADC0809、步进电机、光敏三极管、按键、数码管构成的电路检测环境光的强度；根据教室合理设置的光强开灯和对步进电机窗帘的控制，完成对教室照明回路的智能控制，避免了教室用电的大量浪费。

单片机软件采用C语言编制，采用模块化结构设计、条理清楚、通用性好，便于改进和扩充。

该系统具有体积小，控制方便，可靠性高，专用性强，性价比合理等优点，可以满足各类大、中专院校教室灯光控制的要求，很大程度的达到节能的目的。

System design of illumination intelligence controller for

public

Abstract:Currently light intelligent Control systems are not efficiently used in the classroom. In order to improve the system, based on the theory of the light control and current methods of how to keep control, put forward methods of developing intelligent classroom light control system on the basis of AT89S51 and developed the hardware and software system.

This system uses single chip microcomputer AT89S51 as the intelligent device of control unit, and takes the circuit completed by ADC0890, step motor, light activated triode, button and digitron to test the intensity of light. According to the appropriate layout of turning on the light by light intensity in the classroom and the control of curtain by step motor, it can also complete the intelligent control of illumination loop in the classroom, avoiding large wasting of electrical energy.

The single chip microcomputer software, programmed by C language and designed by modularization, has excellent organization and better currency, and is convenient to improve and extent.

This system had many advantages. For example, the physical volume was small, the system was conveniently controlled, the credibility was high, the appropriation was strong, and its price proportion was ideal, etc. The experiment proved that the system can satisfy the control command of the classroom’s light device, so it could largely reduce the consuming of energy resources.
