摘要在生活中,我们与灯息息相关,我们离不开照明灯。由于社会的发展和进步,我们对照明的需求越来越大,在我们使用并从中获得便利的时候,社会上也存在很多公共场合或者私人场合长明灯现象,必定造成国家能源极大浪费,因此应该引起我们的注意。因此我想到了,制作走廊的声控灯作为我毕业设计。在平时,我们很不注意对灯的使用、对电的控制,浪费电、浪费资源而不知道,接触了这个课题我慢慢明白选题的意义。本文说明了声光控制系统的原理,如果是白天,光线比较明显,我们的照明灯不会开始工作;而当晚上的时候,光线弱,只要出现一定的声音,我们的声控灯开始工作,自动点亮,经过几十秒后自动熄灭。这主要是通过单片机结合了光感、LED显示、声音传感、延时等技术来实现对照明灯的控制,声控灯的优势在于它的方便、节能、保护环境等,让科技使我们的生活更简单、更舒适,我们感谢所有为科技贡献的人们。81068

Sound and light control system based on 51 MCU
Abstract In life, we are closely related with the lamp, we cannot do without lights。 Due to the development and progress of society, our demand for lighting is becoming bigger, in we use and derive a convenient time, society there are many public or private occasions lamp phenomena will lead to great waste of national energy, so should cause our attention。 So I thought, making the corridor voice activated lights as my graduation design。 At ordinary times, we do not pay attention to the use of lights, the control of electricity, waste of electricity, waste of resources and do not know, contact the topic I slowly understand the significance of the topic。 This paper presents the principle of sound and light control system, if it is during the day, the light is obvious, our lighting will not begin to work; and when the evening, the weak light, as long as there is a certain sound, our voice activated lights began to work, automatically light up, after a few seconds after automatically extinguished。 This is mainly through the MCU combines the light perception, LED display sound sensing and delay technology to realize the control of lighting and sound lamps advantages in its convenient, energy saving, environmental protection and other, let the science and technology make our life easier and more comfortable, and we thank all for contributions to science and technology of the people。
