紅外線遙控電源開關(guān)

1、1圖4紅外遙控接收電路原理圖主要由譯碼芯片PT2272編碼開關(guān)雙穩(wěn)繼電器紅外接收頭FPS40915V電源電路等組成.圖4紅外遙控接收電路原理圖...&紅外線遙控電源開關(guān)郭倩物理與電子信息電子信息科學(xué)與技術(shù)專業(yè)摘要：隨著社會的進(jìn)步和生活水平的提高，人們對物質(zhì)生活的要求也越來越高。近年來紅外線遙控技術(shù)在日常生活中應(yīng)用越來越廣泛。紅外線遙控系統(tǒng)具有體積小、功耗低、功能強(qiáng)、成本低、易于控制和使用方便等特點(diǎn)，適用于近距離遙控，具有較好的推廣應(yīng)用價(jià)

2、值。本文介紹一種單路紅外線遙控電源開關(guān)的設(shè)計(jì)方法，采用數(shù)字集成電路實(shí)現(xiàn)遙控電源開關(guān)的手段。在設(shè)計(jì)的電路中由于使用了編碼和解碼器，所以電路抗干擾能力強(qiáng)，且線路簡單，便于電子愛好者自己動(dòng)手制作，在生活中有很好的用途。關(guān)鍵詞：紅外線；編碼；譯碼；PT2262；PT2272InfraredremotecontrolpowerswitchGuoQianHysicsElectronicInfmationElectronicInfmationScie
