声光双控延时开光不仅适用于住宅区的楼道，而且也适用于工厂、办公室、教学楼等公共场所，它具有体积小，外形美观，制作容易，工作可靠等优点，而且降低能耗，在现在世界各种能源都出现紧张且核能的使用安全受到一定质疑的时候，节约能源，对能源最大程度的节约已经成为世界范围的一个大趋势，所以对电能进行合理使用就显得十分必要，虽然这里我设计的仅仅是一个小小的双控开关，但不积跬步无以至千里，只要人人都有节约的意识，身体力行的从身边的点滴做起，那么总的节约量会是十分可观的。此外，它在一定的场所使用还可起防盗作用。因此它是公共场所照明开关的理想选择，使用它之后长明灯问题就会有一个比较好的解决。 本次设计的是一个灵敏度较高的声光控制开关，在夜晚行人只要拍个巴掌就能电路触发。本电路仅使用一只CMOS门电路TC4081BP、一个CRZ2-113F型小型驻极体式电容话筒、一个CdS型光敏电阻器以及若干电阻、电容配合就能将电路触发，使其导通，将电灯打开。它不需要发送关闭信号，由电路自身的延时电路将灯关闭。当灯被打开后，延时电路延时约25s后将灯自动关闭。该电路还具有自动光控作用，在白天由光敏电阻器控制着电路。即使受到声音信号的触发，开关也不会打开。 在此电路的设计中，有三点比较重要，第一是要合理设计三极管的静态工作点，使之处于饱和或截止两状态；第二要调节好电位器，从而使声控开关和光敏电阻具有良好的灵敏度；第三要合理设定延时RC，实际延时时间和理论延时时间总会有差距的 |

Energy saving has become a global tendency while the condition of all kind of the global energy resources, even nuclear energy is becoming more and more serious. In these cases, it is more necessary to use electricity properly. Acoustooptic delay on-off switch, which has an advantage of less spaces in size, better out-looking, easier manufacture and reliable when working, can be both installed in corridors of uptown and public zones such as factories, offices and teaching buildings. There is an old saying that a step by step, a thousand miles. Even it is only a small on-off switch I design, but I believe that the total number of saving will be very appreciable if everyone keeps energy saving in mind. What’s more, as a perfect choice for the public lighting switches, it will gain the function of security and at the same time take the place of everlasting lamp This design is a high sensitivity acoustooptic control switch that triggered by a clap at night. The circuit can be triggered and lighted only by a CMOS gate circuit (TC4081BP), a small electrets capacitor microphone, a Cds photoresistor and several resistors and capacitors. It can turn off the delay circuit itself without shutdown-signal. In addition, the photoresistor holds the circuit in the daytime, which called the function of automatic light-control, so that the switch won’t turn on even triggered by sound signal. There is three points we need to take care in the circuit design. First, the quiescent point of audion must be designed properly in order to stay in a saturate or cut-off state. Secondly, voice switch and photoresistor need a better sensitivity through adjustment of potentiometer. Finally, as the delay time has differences between theory and fact, we should set the delay RC properly. 为了连贯我调整了一下个别句子的语序，楼主注意一下吧！ |
