摘要

随这社会的不断发展，人们越发的意识到了环境对我们的重要性，但是工业的发展以及人们对能源的需求不可避免的会造成环境的破坏，我国大部分的发电厂为火力发电厂，水力风力等其他的清洁能源发电，只站少部分，火力发电对煤矿资源的消耗是十分巨大的，由此造成对环境的影响也是可想而知的。庆幸的是人们也越来越重视这方面的问题，于是可以有效的减少能源消耗，促进节能减排的智能楼道灯开始出现在人们的视野中。

现代思想的进步，科技的发展，以及技术的不断的更新，大量的高新技术产品出现在人们身边，人们的生活发生了巨大的变化，与此同时新技术的出现及运用也为现代环保打下了坚实的基础。

智能楼道灯光控制系统又多个模块所组成，其核心是单片机，在由多个元器件及传感器一起组成。本次设计采用的是 STC89C52单片机，通过对多个因素的综合判断来决定灯光的亮灭，实现了楼道内无人或者光照充足及无声音时楼道灯光熄灭，有人到来或有声音且光照不足时自动开启灯光。且在人走后灯光也将熄灭，非常的节能环保，符合绿色生活的理念。

Abstract

With the continuous development of the society, people are more and more aware of the importance of the environment to us, but the development of industry and people's demand for energy will inevitably cause environmental damage. For example, the source of power in our country is partly from thermal power generation, which inevitably causes great damage to the environment due to the use of coal and the use and exploitation of coal. Fortunately, people are paying more and more attention to this issue, so intelligent corridor lamps which can effectively reduce energy consumption and promote energy conservation and emission reduction are beginning to appear in people's vision.

The progress of modern thought, the development of science and technology, and the constant renewal of technology, a large number of high-tech products appear around people, people's lives have undergone tremendous changes, at the same time, the emergence and application of new technology has laid a solid foundation for modern environmental protection.

Intelligent corridor lighting control system consists of minimal system of single chip computer, human perception module, intensity of care detection module, light control module, sound detection module, power module and light bulb. In this paper, STC89C52 MCU as the core, through the use of light intensity, infrared human body induction and sound intensity detection combined with active and passive detection method, the corridor lights are extinguished when there is no one in the corridor or when there is sufficient light or no sound, and the lights are automatically turned on when someone arrives or there is sound and the light is insufficient. When people {fill the corridor or go out of the corridor, the corridor lights will be automatically extinguished after a minute delay. In the daytime, when someone walks by, the lamp will not turn on, which achieves the purpose of energy saving

Key words: human perception, environmental protection, energy saving and emission reduction, human perception, intelligent corridor lighting control, light intensity detection, sound intensity detection
