声光控楼道灯电路的安装

摘要

本次电子实习内容为“声光控楼道灯电路的安装”，主要包括对电路中各个器件的了解和使用、电路的控制原理的理解、电路的实物焊接、电路的调试和错误分析。

原理电路中包括桥式整流电路、CD4011集成块、驻极体话筒、光敏电阻、稳压管、三极管和二极管等。

声光控楼道灯电路是利用声音和光共同控制灯泡的亮灭的电路。

灯泡白天主要受光敏电阻控制，无论是否有声音只要达到一定的光的强度就不会亮；晚上主要受声音控制，有声音时就会亮起，这样就给给人们的生活带来了很大的方便，同时也是节约能源的一种途径。

音频红外转发器和声控灯

摘要

本次电子实习第一部分设计了一个红外通信收发系统。

该系统由信号产生模块、红外光发送模块和红外光接收模块三部分构成，实现对信号的产生、发送、接收以及实现对信号的滤波消除干扰和功率放大。

系统使用万能电路板和光发射接收二极管以及相关放大去噪电路制成。

最终完成的系统可以用电视中音频信号或者收音机、MP3等的音频做输入信号发射，在三米外能够接收到红外信号，且能够清楚地听到声音。

第二部分是声控灯。

声光控楼道灯是一种声光控电子照明装置，它能避免繁琐的人工开灯，同时具有自动延时熄灭的功能，更加节能，且无机械触点、无火花、寿命长，广泛应用于各种建筑的楼梯过道、洗手间等公共场所。

只有在天黑以后，当有人走过楼梯通道，发出脚步声或其它声音时，楼道灯会自动点亮，提供照明，当人们进入家门或走出公寓，楼道灯延时几分钟后会自动熄灭。

在白天，即使有声音，楼道灯也不会亮，可以达到节能的目的。

此实习报告重点介绍了其实现方法和具体细节，及制作过程中遇到的问题和相应的解决方案。

第一章概述

1.1声控灯的发展及应用

日常生活是一个充满声音的世界，每天你都会听到各种各样的声音，声音是无处不在，无时不在的。

然而，声音除了丰富我们的生活外，它还有很多用处。

以往的声控开关大多都是应用模拟电子技术进行设计，分立元件多，不可靠，如今单片机技术已经相当成熟，运用单片机可以设计出智能型的声控开关，电路设计好后，运用软件编程来实现其功能，灵活方便，修改简单。

目前许多声控开关的平均使用寿命不长，主要是因为电路作频繁的开关，启动电流非常大，导致功率元件可控硅由于过载而损坏。

本文中采用开关电压过零保护技术，可消除白炽灯开启瞬间的大电流冲击，有效地防止可控硅元件启动时电流过载，大大地延长了开关使用寿命，并且可以起到保护灯泡的作用。

声控电路已成为人们日常生活中不可缺少的必须品，现在声控灯主要应用于楼道里的照明灯，它不需要开关，当有人经过时会自动亮：

广泛用于走廊、楼道招待所灯公共场所等，给人们的生活带来极大的方便。

因此，得到了广泛的应用。

声控电路是声音和光控制电路工作的电子开关。
