In addition, it can also be used in certain places from the theft. It is ideal for public places, lighting switch selection, known as the light of the long nemesis.The design is a high sensitivity of sound and light control switch, pedestrians in making a circuit to trigger a hand can. This circuit uses only a CMOS gate TC4081BP, a small CRZ2113Ftype electret condenser microphone, a photosensitive resistor CdS type and number of resistors, capacitors with will be able to trigger the circuit, so that it turns on, lights turn on. It does not send a shutdown signal and the delay circuit from the circuit itself will light off. When the lamp is turned on, the delay circuit delay of about 25s after the lights turn off automatically. The circuit also has an automatic light control role in the day by the light dependent resistor control circuit. Even if the sound signal by the trigger, the switch will not open.In this circuit design, to pay attention to three points, the first transistor to the rational design of the static operating point, so that in the twostate saturation or cutoff。 the third set to a reasonable delay RC, practical and theoretical delay time there will always be gaps.Keywords: sound and light dualcontrol powersaving delay opening引言近年來,城市居民住宅越來越趨向高層化。樓道照明燈如果能做到隨手關(guān)燈,將是一個(gè)極大的能源消耗,以一棟六單元十二層樓房為例:每層安裝一只15瓦的燈泡,就是72只燈泡。一般住戶在開燈后往往忘了或不愿意再費(fèi)事去專門關(guān)燈。它可以在開燈后一定時(shí)間內(nèi)自動(dòng)熄滅。聲光雙控延時(shí)開關(guān)體積小,外形美光,制作容易,且節(jié)能環(huán)保,是當(dāng)今世界的主潮流。隨著全球經(jīng)濟(jì)一體化,發(fā)達(dá)國家產(chǎn)業(yè)調(diào)整的步伐進(jìn)一步加快,一般照明電器產(chǎn)品生產(chǎn)大量向發(fā)展中國家轉(zhuǎn)移,而中國又是一個(gè)比較適合的國家,一是中國具備生產(chǎn)這些產(chǎn)品的條件,而是勞動(dòng)力成本比較低,從而使中國逐步成為照明電器產(chǎn)品出口大國。因此我設(shè)計(jì)一個(gè)聲光雙控延時(shí)開關(guān)來解決此浪費(fèi)問題。第一章 設(shè)計(jì)流程此設(shè)計(jì)是為了實(shí)現(xiàn)聲控光控延時(shí)開關(guān)的功能。所設(shè)計(jì)的電路分為五個(gè)模塊:電源模塊,信號(hào)收集模塊,信號(hào)處理模塊,延時(shí)模塊和被控制模塊。信號(hào)收集模塊分為聲音信號(hào)收集模塊和光信號(hào)收集模塊。光信號(hào)收集模塊將光強(qiáng)度的改變轉(zhuǎn)變?yōu)殡妷旱母淖?,與聲音信號(hào)一起控制芯片的輸入。延時(shí)模塊是在信號(hào)處理模塊的作用下工作,起到延時(shí)的作用。
