智能控制照明系统的研究
摘要
随着计算机网络、通信、控制等技术的发展,智能建筑的发展越来越迅猛。目前,国内大多数智能建筑存在效率低、能耗高的现象。就智能建筑的照明系统来说,许多地方的灯经常是从早到晚开着的,不管这些房间或楼道是否有人,也不管有多少人。或者,当自然光照度很好时,灯不能及时关闭;反之,当自然光照度难以满足人的需求时,又不能及时打开灯光。这种照明方式,不仅造成能源的浪费,而且不能满足人对照明的基本需求,同时也给人的视力造成了很大的影响。现代照明除了满足人的基本生活、学****要求之外,将更注重能量的节省和使用上的便利,以及满足人类工程学的个性方面的要求。特别是近年来大厦内利用计算机工作的人员比例上升,不同视觉要求的工作的数量和复杂程度大大增加。所以要做到合理、经济、节能,首先应采用先进成熟的技术和产品,如电光源、灯具、照明控制系统。因此,适应不同个人和工作需要,结合自动调节与手动调节的智能化照明系统已经成为必不可少了。
本篇论文介绍了就是基于单片机AT89C51的室内灯光控制系统的研究和开发。本系统是以单片机为控制器的核心,再连接外围电路,实现照明灯具的智能控制。系统通过人体信号采集电路对人体信号采集和光信号采集电路对光信号采集以及相应的处理并输入给单片机,单片机对输入信号判断并输出信号来控制学校教室内灯光的开关和亮度。

Intelligent control lighting system research
Abstract
Along with work, communication and control technology, the development of the intelligent building development is more and more rapidly. At present, the domestic most intelligent building existing low efficiency and high energy consumption of the phenomenon. Smart architecture lighting systems, it is often many places the lamp of from morning till night, whether these open room or corridor whether anyone, no matter how many people. Or, when natural light is very good, the lamp can not be closed down, Conversely, when natural light to meet people's needs, and cannot seasonable open lighting. This kind of lighting system, not only cause a waste of energy, and can meet the people of lighting basic needs, but also to the person's eyesight caused great influence. Contemporary illume except for satisfying the people's basic living, learning requirements besides, will pay more attention to energy saving and ease of use in the, as well as satisfying ergonomics personality requirements. Especially in recent years, the building by puter work of the staff ratio rose, different visual demanding job and quantity of plex degree increase greatly. So to achieve reasonable, economic, energy saving, first of all, should adopt advanced and mature technology and pr
