IR remote control

1. Inokodzera macoded infrared remote control midziyo yemumba;

2. Inogona kudzora kure kure midziyo yemumba yakawanda;

3. Iine kiyi yekudzidza / yekudzora multiplexing, 5 ~ 10 makiyi ekusarudza mudziyo, uye 10 ~ 20 makiyi ekudzora basa.Kiyi yekusarudza mudziyo uye yega yega kiyi yekudzora basa pamwe chete vanoziva kutonga kwemudziyo;

4. Kiyi yekusarudza mudziyo uye akasiyana makiyi ekudzora basa anogona kushandiswa kudzidza nekudzora mabasa akajairika emidziyo yakawanda;

5. Mari shoma uye simba rinopesana nekupindira.

Principle

Iyo iri kure controller inoumbwa neiyo infrared inogamuchira uye kufambisa dunhu, siginecha yekumisikidza dunhu, yepakati controller 8031, chirongwa uye data memory, keyboard uye chimiro chechiratidzo chedunhu.

Remote control ine matunhu maviri: kudzidza mamiriro uye kutonga nyika.Kana iyo kure kure iri munharaunda yekudzidza, nguva imwe neimwe mushandisi anodzvanya kiyi yekudzora, iyo infrared inogamuchira dunhu inotanga kugamuchira yekunze infrared chiratidzo, uye panguva imwechete inoishandura kuita chiratidzo chemagetsi, uye obva aona, kuumbwa, amplification, uye ipapo CPU inogara ichiienzanisa.Iyo bhinari data yeimwe sampling point inochengetwa mune yakasarudzika yekuchengetera unit ine 8 bits seyuniti yekuzotonga gare gare yechishandiso.Kana iyo remote control iri munzvimbo yekutonga, pese mushandisi paanodzvanya kiyi yekudzora, iyo CPU inoverenga nhevedzano yebhinari data kubva kune yakasarudzwa yekuchengetera unit, uye inoburitsa serially (iyo nguva yekupindirana pakati pebits nebits yakaenzana nenguva yenguva. panguva yekuenzanisira ) Kune chiratidzo chekubata dunhu, panguva imwe chete, iyo modulation dunhu inoita chiratidzo modulation.Mushure mekunge chiratidzo chemodulation chawedzerwa, chinoburitswa neiyo infrared emitting diode, kuitira kuti uone kutonga kwechishandiso chinoenderana nekiyi.
