Muhupenyu hwedu hwazvino, kudzora kure kure kudzora kwave kuita chishandiso chakanakira isu kudzora zvishandiso zveimba. Kubva ku terevhizheni kuenda kumhepo inogadzira mhepo, uye kune vatambi valtimedia, kushandiswa kwezvinhu zvinangwa zvezvinhu zviri Ubiquitous. Nekudaro, musimboti wekushanda kumashure kwekudzora kure kure kudzora, kunyanya kujairana uye maitiro emununure, haazivikanwe zvishoma. Chinyorwa chino chichasvetukira muchiitiko chekuratidzira kwekudzora kure, kufumura maitiro ayo anobudirira uye akavimbika.
Modulation: Iyo yekugadzirira nhanho yechiratidzo
Kujairana ndiyo yekutanga nhanho mukushambadzira, iyo inosanganisira kushandura kuraira ruzivo mune chimiro chakakodzera kutapurirana zvisina waya. Mukudzora kure kure kudzora, maitiro aya anowanzoitwa kushandisa pulse chinzvimbo modulation (PPM).
Nheyo dzePPM modulation
PPM ndeyekunyora modulation maitiro ayo anozivisa ruzivo nekuchinja nguva uye kupatsanura kwepurases. Bhatani rega rega pane kure kudzora rine kodhi yakasarudzika, iyo muPPM inoshandurwa kuita nhevedzano yemasaini masaini. Upamhi uye kuparadzaniswa kwemapurases inosiyana zvichienderana nemirairo yemirambidziro, ichiva kusaziva kusaziva uye kuzivikanwa kwechiratidzo.
Kutakura kutakura
Pahwaro hwePPM, chiratidzo chinoda zvakare kuunganidzwa kune yakatarwa yekutakura frequency. Iyo yakajairika carrier frequency is 38khz, iyo inogara ichishandiswa zvakanyanya mukudzora kure kure kudzora. Maitiro ekunyorwa anosanganisira kushandura iyo yakakwira uye yakaderera masaini mune electromagnic mafungu eiyo inoenderana frequency, ichibvumira chiratidzo kuti uwedzere kupindira.
Signal Amplization uye Emission
Iyo sighlated chiratidzo inosimbiswa kuburikidza neyemukati yekuve nechokwadi kuti ine simba rakakwana rekutapurirana zvisina maaini. Pakupedzisira, chiratidzo chakaburitswa kuburikidza nekunyudzwa kwekunyorera diode (LED), kugadzira iyo infrared mwenje wave kuisimbisa mirairo kune iyo chinangwa chechinangwa.
Demodulation: chiratidzo chekugamuchira uye kudzoreredzwa
Demodulation ndiyo nzira inosimbisa yekujairwa, ine mutoro wekudzoreredza iyo yakagashirwa chiratidzo mugwaro rekutanga rekuraira.
Chiratidzo
Iyo infrared inogamuchira Diode (Photodiode) inogamuchira yakabuda infrared chiratidzo uye inoshanduka kuita chiratidzo chemagetsi. Iyi nhanho ndiyo kiyi yekubatanidza muchiratidzo chekutapurirana kuita nekuti inobata zvakananga kunaka uye kurongeka kwechiratidzo.
Kusefa uye demodulation
Iyo yakagashirwa chiratidzo yemagetsi inogona kunge iine ruzha uye inoda kuongororwa kuburikidza nefaira kuti ibvise ruzha uye kuchengetedza masaini padhuze neyekutakura frequency. Pashure pacho, iyo demoddulator inoona chinzvimbo chemapuranga kubva kuPPM Nheyo, inodzoreredza ruzivo rwekutanga rwakatangira.
Chiratidzo chekugadzirisa uye kushongedza
Chikwangwani chakachinjirwa chinogona kuda chimwezve chiratidzo chekugadzira, senge kukwirira uye kuumba, kuve nechokwadi chekugadzikana uye chokwadi chechiratidzo. Iyo yekugadzirisa chiratidzo inobva yatumirwa kune micrococontroller yekukodha, iyo inoratidza iyo yekuzivikanwa kodhi kodhi uye kodhi yekodhi zvichienderana neyekutonga manhamba emubhadharo.
Kuurayiwa kwemirairo
Kamwe kukoka kwacho kwakabudirira, microcontroller inoenderana nemirairo inoenderana neyakaora
Mhedziso
Iyo modulation uye demodation process yeiyo infrared kure kudzora ndiyo musimboti wekushanda uye akavimbika wekutaurirana. Kuburikidza nekuita uku, tinogona kuzadzisa kudzora chaiko kwemidziyo yemumba. Nekuenderera mberi kwekufambira mberi kwehunyanzvi, infrared kure kure kudzora kunogara kuchisimbiswa uye kukwidziridzwa kuti tisangane nezvinodiwa zvedu zviri kukura. Kunzwisisa maitiro aya hakuiti kunotibatsira kushandisirwa kure kure kudzora zviri nani asiwo kunotibvumira kuti tive nekunzwisisa kwakadzama kwehunyanzvi hwekutaurirana.
