Muhupenyu hwedu hwemazuva ano, ma infrared remote controls ave chishandiso chiri nyore kwatiri kudzora midziyo yemumba. Kubva kumaterevhizheni kusvika kuma air conditioners, uye kusvika kuma multimedia players, kushandiswa kwetekinoroji ye infrared kuri kwose kwose. Zvisinei, musimboti wekushanda kwe infrared remote control, kunyanya maitiro e modulation ne demodulation, hauzivikanwi zvakanyanya. Chinyorwa chino chichaongorora kugadzirisa masaini e infrared remote control, zvichiratidza nzira yayo yekutaurirana inoshanda uye yakavimbika.
Kuchinja-chinja: Danho rekugadzirira chiratidzo
Kuchinja-chinja ndiyo nhanho yekutanga mukutumira masaini, iyo inosanganisira kushandura ruzivo rwemirairo kuita fomati yakakodzera kutumira isina waya. Muchinodzora kure che infrared, maitiro aya anowanzoitwa uchishandisa Pulse Position Modulation (PPM).
Nheyo dzePPM Modulation
PPM inzira iri nyore yekushandura mashoko nekuchinja nguva uye nzvimbo yemapulse. Bhatani rega rega riri pa remote control rine kodhi yakasiyana, iyo muPPM inoshandurwa kuita nhevedzano yemasignali epulse. Upamhi nenzvimbo yemapulse zvinosiyana zvichienderana nemitemo yekunyora, zvichiita kuti chiratidzo chive chakasiyana uye chizivikanwe.
Kuchinja Kwemutakuri
Zvichienderana nePPM, chiratidzo chinofanirawo kugadziriswa kune frequency chaiyo yekutakura. Frequency yakajairika yekutakura i38kHz, inova frequency inoshandiswa zvakanyanya mu infrared remote controls. Maitiro ekushandura anosanganisira kushandura mazinga akakwira neakaderera echiratidzo chakanyorwa kuita ma electromagnetic waves efrequency inoenderana, zvichibvumira chiratidzo kuti chipararire zvakanyanya mumhepo uku chichideredza kupindira.
Kuwedzera kweChiratidzo uye Kubuda
Chiratidzo chakagadziriswa chinowedzerwa kuburikidza neamplifier kuti ive nechokwadi chekuti chine simba rakakwana rekutumira pasina waya. Pakupedzisira, chiratidzo chinoburitswa kuburikidza ne infrared emitting diode (LED), zvichiita mafungu echiedza che infrared chinoendesa mirairo yekudzora kune mudziyo waunoda.
Kuderedza Kushandiswa Kwezviratidzo: Kugamuchira Zviratidzo uye Kudzoreredza
Kuchinja-chinja inzira yekuchinjisa, ine basa rekudzorera chiratidzo chakagamuchirwa muruzivo rwemirairo rwepakutanga.
Kugamuchirwa kweChiratidzo
Diode yekugamuchira masaini e infrared (Photodiode) inogamuchira chiratidzo che infrared chinobuda uye inochishandura kuita chiratidzo chemagetsi. Danho iri ndiro chinhu chakakosha mukufambisa masaini nekuti rinokanganisa zvakananga kunaka uye kururama kwechiratidzo.
Kusefa uye Kuderedza Kushandiswa kweMasevhisi
Chiratidzo chemagetsi chinogamuchirwa chinogona kunge chine ruzha uye chinofanira kugadziriswa kuburikidza nesefa kuti chibvise ruzha uye chichengetedze masaini ari pedyo nefrequency yekutakura. Zvadaro, demodulator inoona nzvimbo yemapulses zvichienderana nePPM, ichidzorera ruzivo rwepakutanga rwakanyoreswa.
Kugadziriswa kweChiratidzo uye Kugadzirisa
Chiratidzo chakabviswa simba chingada kugadziriswa kwechiratidzo zvakare, zvakaita sekuwedzera simba uye kuumbwa, kuti chive nechokwadi chekugadzikana uye kururama kwechiratidzo. Chiratidzo chakagadziriswa chinozotumirwa ku microcontroller kuti chigadziriswe, iyo inoratidza kodhi yekuzivikanwa kwemudziyo uye kodhi yekushanda zvichienderana nemitemo yekodhi yakatarwa.
Kuitwa Kwemirayiro
Kana decoding yabudirira, microcontroller inoita mirairo inoenderana zvichienderana nekodhi yekushandisa, yakadai sekudzora switch yemudziyo, kugadzirisa vhoriyamu, nezvimwewo. Maitiro aya anoratidza kupera kwekutumira masaini e infrared remote control.
Mhedziso
Maitiro ekushandura uye kubvisa ma "infrared remote control" ndiwo musimboti wenzira yayo yekutaurirana inoshanda uye yakavimbika. Kuburikidza nemaitiro aya, tinogona kuwana kutonga kwakarurama kwemidziyo yemumba. Nekufambira mberi kwetekinoroji, ma "infrared remote control" ari kugara achigadziriswa uye achivandudzwa kuti asvike pazvinodiwa zvedu zvekudzora zviri kukura. Kunzwisisa maitiro aya hakungotibatsiri chete kushandisa ma "infrared remote control" zviri nani asiwo kunotibvumira kunzwisisa kwakadzama kwetekinoroji yekutaurirana isina waya.
