聲光雙控延時開光不僅適用于住宅區(qū)的樓道，而且也適用于工廠、辦公室、教學(xué)樓等公共場所，它具有體積小，外形美觀，制作容易，工作可靠等優(yōu)點，而且降低能耗，在現(xiàn)在世界各種能源都出現(xiàn)緊張且核能的使用安全受到一定質(zhì)疑的時候，節(jié)約能源，對能源最大程度的節(jié)約已經(jīng)成為世界范圍的一個大趨勢，所以對電能進(jìn)行合理使用就顯得十分必要，雖然這里我設(shè)計的僅僅是一個小小的雙控開關(guān)，但不積跬步無以至千里，只要人人都有節(jié)約的意識，身體力行的從身邊的點滴做起，那么總的節(jié)約量會是十分可觀的。此外，它在一定的場所使用還可起防盜作用。因此它是公共場所照明開關(guān)的理想選擇，使用它之后長明燈問題就會有一個比較好的解決。 本次設(shè)計的是一個靈敏度較高的聲光控制開關(guān)，在夜晚行人只要拍個巴掌就能電路觸發(fā)。本電路僅使用一只CMOS門電路TC4081BP、一個CRZ2-113F型小型駐極體式電容話筒、一個CdS型光敏電阻器以及若干電阻、電容配合就能將電路觸發(fā)，使其導(dǎo)通，將電燈打開。它不需要發(fā)送關(guān)閉信號，由電路自身的延時電路將燈關(guān)閉。當(dāng)燈被打開后，延時電路延時約25s后將燈自動關(guān)閉。該電路還具有自動光控作用，在白天由光敏電阻器控制著電路。即使受到聲音信號的觸發(fā)，開關(guān)也不會打開。 在此電路的設(shè)計中，有三點比較重要，第一是要合理設(shè)計三極管的靜態(tài)工作點，使之處于飽和或截止兩狀態(tài)；第二要調(diào)節(jié)好電位器，從而使聲控開關(guān)和光敏電阻具有良好的靈敏度；第三要合理設(shè)定延時RC，實際延時時間和理論延時時間總會有差距的 |

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. 為了連貫我調(diào)整了一下個別句子的語序，樓主注意一下吧！ |
