Uburyo modulasiyo nuburyo bwo kwangiza bwibikorwa bya kure bya kure

Mubuzima bwacu bwa none, kugenzura kure bwa kure byahindutse igikoresho cyoroshye cyo kugenzura ibikoresho byo murugo. Duhereye kuri tereviziyo kugera ku mbuga y'inkoni, no ku bakinnyi ba Multimediya, gushyira mu bikorwa ikoranabuhanga rya infrad ni hose. Ariko, ihame rikora inyuma yubuyobozi bwa kure cyane, cyane cyane modulation nuburyo bwo kwangiza, ntirizwi cyane. Iyi ngingo izacengera mubimenyetso byo gutunganya ibimenyetso bya kure bya Infraf, byerekana uburyo bwo gutumanaho bunoze kandi bwizewe.

Guhindura: Icyiciro cyo kwitegura ibimenyetso

Guhindura nintambwe yambere yo kwanduza ibimenyetso, bikubiyemo guhindura amakuru yubuyobozi muburyo bukwiye bwo kohereza. Mu bugenzuzi bwa kure bwa Infrad, iyi nzira isanzwe ikorwa ukoresheje module ihinduranya (ppm).

Amahame ya ppm modulation

PPM ni tekinike yoroshye yerekana amakuru muguhindura igihe na spacing ya Pulses. Buri buto ku butegetsi bwa kure ifite kode idasanzwe, muri PPM ihindurwamo ibimenyetso bya pulse. Ubugari na spricy of Plisse biratandukanye ukurikije amategeko ya coding, bemeza umwihariko kandi umenyeshe ikimenyetso.

Guhindura abatwara

Hashingiwe kuri PPM, ikimenyetso nacyo gikeneye kandi guteshuka kumwanya wihariye. Ifishi isanzwe ni 38khz, niryo dukunze gukoreshwa cyane mubugenzuzi bwa kure. Inzira ya modulation ikubiyemo guhindura urwego rwo hejuru kandi rwo hasi rwanditseho ibimenyetso bya electromagnetic, yemerera ikimenyetso cyo gukwirakwiza kure mu kirere mugihe kigabanyijemo kwivanga.

Ibimenyetso byongera no guhuriramo

Ikimenyetso cya moduite kizuzwa unyuze muri amplifier kugirango ibone imbaraga zihagije zo kohereza. Hanyuma, ikimenyetso gisohoka binyuze muri Diode ya Infrared (LED), gukora urumuri rwinshi rwaka rutanga amategeko kubikoresho bigenewe.

Demodulation: Kwakira ibimenyetso no kugarura

Demodulation nuburyo butandukanye bwo guhinduranya, bushinzwe kugarura ibimenyetso byakiriwe mumakuru yambere.

Kwakira ibimenyetso

Gukira Diode (Photodiode) yakira ibimenyetso bya leta byasohotse kandi bihindura mubimenyetso byamashanyarazi. Iyi ntambwe ni ihuriro ryingenzi mubikorwa byo kwandura ibimenyetso kuko bigira ingaruka muburyo bwiza kandi bwuzuye bwikimenyetso.

Gushungura no kwaguka

Ikimenyetso cyamashanyarazi gishobora kuba kirimo urusaku kandi gikeneye gutunganywa binyuze muyungurura kugirango ukure urusaku no kugumana ibimenyetso hafi yinkunga. Nyuma yaho, Demodulator imenya umwanya wimpapuro ukurikije ihame rya PPM, kugarura amakuru yumwimerere.

Gutunganya ibimenyetso no gutesha agaciro

Ikimenyetso cya demodilod kirashobora gusaba ubundi buryo bwo gutunganya ibimenyetso, nko kongera no gushushanya, kugirango urebe neza kandi neza ibimenyetso. Ikimenyetso cyatunganijwe noneho cyoherejwe kuri microcontroller kuri decoding, kigaragaza kode iranga igikoresho na kode yimikorere ikurikije amategeko ya PRANT.

Gushyira mu bikorwa amategeko

Indwara ya scoding iragenze neza, microcontroller ikora amabwiriza ajyanye nicyemezo cyibikorwa, nko kugenzura imibumbe, nibindi.

Umwanzuro

Imyitwarire hamwe nuburyo bwo kwangiza ibicuruzwa bya kure ni intangiriro yuburyo bwo gutumanaho neza kandi bwizewe. Binyuze muriyi nzira, turashobora kugera ku kugenzura neza ibikoresho byo murugo. Hamwe no gutera imbere kwikoranabuhanga, infrad ya kure kandi ihora ahora no kuzamurwa kugirango ihuze ibikenewe byinshi. Gusobanukirwa iki gikorwa ntabwo bidufasha gusa kugenzura neza kugenzura neza ariko natwe bitwemerera gusobanukirwa byimbitse ikoranabuhanga mu itumanaho adafite umugozi.
