智能家居照明控制系统方案

摘要

随着科学技术的不断发展，人类社会迎来了电子信息时代。而智能家居照明控制技术随着智能化住宅的蓬勃兴起而飞速发展，成为照明控制技术发展的一个重要方向。因此，针对现有的智能照明控制系统的优缺点，根据人们的行为模式和住宅的光环境决定照明的控制规律，研究智能家居照明控制系统对提高人们的生活质量、节约能源和提倡绿色照明等具有十分重要的现实意义。

本论文主要从智能照明的基本概念、照明质量、家居照度标准、照明方式和种类、电光源的选择、智能照明控制系统的控制方式、智能家居照明控制系统设计等方面研究了家居式照明系统的设计的常用的方法，并且给出了智能化住宅各房间的典型照明技术。同时指出在进行照明系统的设计时，不仅要根据场合的具体环境使照明系统能够实现视觉需求的光环境，同时要注意节约能源，实现绿色照明。

本论文分析了现有的智能照明控制方式的控制原理及其优缺点，设计了基于家居环境的智能照明系统，并介绍了该系统的功能及软、硬件的设计方法。系统中的控制装置采用AT89S51单片机作为控制器，用C语言编程，采用光敏二极管检测光照度和PWM方式进行调光，同时设计了正负12伏直流供电电源。在具体硬件设计中，本文主要设计了光照度检测、显示及补偿部分，经过调试，该部分完全能够实现设计系统的功能。此外，还设计了灯光调节部分，根据环境调光或进行手动调节，同时还预留了RS232串行接口，为今后采用数字网络化调节的应用预留了空间。

Abstract

With the development of science and technology，human come in the era of electronic information. So the technology of the electronic home lighting control make a great development with the rise of electronic home. So the research on electronic home lighting control system is of great practical significance to improve people’s life quality and to promote gre en lighting against with the Advantages and disadvantages of the existing Intelligent Lighting Control System and according to people's behavior patterns of residential and light environment.

This paper mainly does research in the commonly used method of the design of the home-lighting systems, according to the basic concept of smart lighting, lighting quality, home illumination standards, methods and types of lighting, the choice of light source, the control of the electronic home and gives the typical residential lighting technology of every room. At the same time this paper pointed out that in the design of lighting systems, not only need according to the specific occasion to achieve the demand lighting environment, but also should pay attention to energy conservation and green lighting.

This paper makes an analysis on the control theory and the advantages and disadvantages of the existing smart lighting. It designs the electronic home lighting systems and introduces the method of the software system and hardware system in designing. The controller of this system uses AT89S51 and makes program with C language. It uses the photodiode to detect light and make a dimming in the PWM way.At the same time it designs a plus and minus 12-volt DC power supply. In the specific design of hardware this paper mainly designs for lighting detection, display and some compensation. After commissioning, the design can completely realize the function of system. Furthermore, it reserves the RS232 interface，make the space for the using digital networks in future.
