Uburyo bwo guhindura no gukuramo igenzura rya infrared rikora

Mu buzima bwacu bwa none, uburyo bwo kugenzura ikoranabuhanga rya infrared bwabaye igikoresho cyoroshye kuri twe cyo kugenzura ibikoresho byo mu rugo. Kuva kuri televiziyo kugeza kuri conditioner, ndetse no ku bikoresho bikoresha ikoranabuhanga rya multimedia, ikoreshwa ry'ikoranabuhanga rya infrared riri hose. Ariko, ihame ry'imikorere ry'uburyo bwo kugenzura ikoranabuhanga rya infrared, cyane cyane uburyo bwo guhindura no gukuramo amakuru, ntabwo rizwi cyane. Iyi nkuru izasuzuma uburyo bwo gutunganya ibimenyetso bya infrared, igaragaza uburyo bwo gutumanaho bukora neza kandi bwizewe.

Guhindura imiterere y'ishusho: Icyiciro cyo kwitegura ikimenyetso

Guhindura imiterere y'amajwi ni intambwe ya mbere mu kohereza amajwi, bikubiyemo guhindura amakuru y'amabwiriza mu buryo bukwiriye kohereza amajwi nta mugozi. Muri remote control ya infrared, ubusanzwe iyi nzira ikorwa hakoreshejwe Pulse Position Modulation (PPM).

Amahame yo Guhindura PPM

PPM ni uburyo bworoshye bwo guhindura amakuru buhindura igihe n'intera y'imivuduko. Buri buto iri kuri remote control ifite kode yihariye, muri PPM ihinduka urukurikirane rw'ibimenyetso by'imivuduko. Ubugari n'intera y'imivuduko biratandukanye hakurikijwe amategeko agenga kode, bikerekana umwihariko n'ubushobozi bw'ikimenyetso.

Ihindagurika ry'Umukoresha

Hashingiwe kuri PPM, ikimenyetso nacyo kigomba guhindurwa ku murongo runaka w’umuyoboro. Umuyoboro usanzwe w’umuyoboro ni 38kHz, ari wo murongo ukoreshwa cyane mu byuma bigenzura kure bya infrared. Uburyo bwo guhindura imiterere y’ibimenyetso burimo guhindura urugero rwo hejuru n’urwo hasi rw’ibimenyetso byanditseho mo imiraba ya elegitoroniki y’umuyoboro ujyanye na byo, bigatuma ikimenyetso gikomeza gukwirakwira mu kirere mu gihe bigabanya ingaruka mbi.

Kongera Ingufu n'Isohora ry'Ibimenyetso

Ijwi rihinduka ryongerwamo imbaraga binyuze mu cyuma gitera imbaraga kugira ngo gihabwe imbaraga zihagije zo kohereza ubutumwa budafite umugozi. Amaherezo, ijwi risohoka binyuze muri diode isohora urumuri rwa infrared (LED), rigakora urumuri rwa infrared rutanga amabwiriza yo kugenzura igikoresho kigenewe.

Guteza imbere ibikorwa: Kwakira no gusana ibimenyetso

Guhindura imiterere y'amakuru ni inzira inyuranyije n'iy'ihinduka ry'amakuru, ishinzwe gusubiza ikimenyetso cyakiriwe mu makuru y'amabwiriza y'umwimerere.

Kwakira ibimenyetso

Diode yakira infrared (Photodiode) yakira ikimenyetso cya infrared gisohoka kikagihindura ikimenyetso cy'amashanyarazi. Iyi ntambwe ni ingenzi mu nzira yo kohereza ibimenyetso kuko bigira ingaruka ku buryo butaziguye ku bwiza no ku kuri kw'ikimenyetso.

Gushungura no Guhindura Imiterere y'Ibintu

Ibimenyetso by'amashanyarazi byakiriwe bishobora kuba birimo urusaku kandi bigomba gutunganywa binyuze mu kayunguruzo kugira ngo urusaku rukureho kandi rugumane ibimenyetso hafi y'umuvuduko w'umuyoboro. Nyuma yaho, demodulator imenya aho pulses ziri hakurikijwe ihame rya PPM, igasubiza amakuru y'umwimerere yari yashyizwemo.

Gutunganya no Gusobanura Amajwi

Ikimenyetso cyagabanijwe gishobora gusaba ko ibimenyetso bikomeza gutegurwa, nko kongera no gushushanya, kugira ngo ikimenyetso gihamye kandi gihamye. Ikimenyetso cyatunganyijwe cyoherezwa kuri microcontroller kugira ngo imenyekane, ikagaragaza kode y'igikoresho na kode y'imikorere hakurikijwe amategeko yashyizweho.

Ishyirwa mu bikorwa ry'amabwiriza

Iyo gusesengura neza, microcontroller ishyira mu bikorwa amabwiriza ajyanye nayo ashingiye ku kode y'imikorere, nko kugenzura uburyo igikoresho gihinduka, guhindura ijwi, nibindi. Iyi gahunda igaragaza ko ikimenyetso cya nyuma cya infrared remote control kirangiye.

Umwanzuro

Uburyo bwo guhindura no gukuramo ikoranabuhanga rya infrared ni ingenzi mu buryo bw'itumanaho ryayo bwiza kandi bwizewe. Binyuze muri ubu buryo, dushobora kugera ku kugenzura neza ibikoresho byo mu rugo. Hamwe n'iterambere rihoraho ry'ikoranabuhanga, ikoranabuhanga rya infrared rihora rivugururwa kandi rivugururwa kugira ngo rihuze n'ibyo dukeneye mu kugenzura. Gusobanukirwa ubu buryo ntibidufasha gusa gukoresha neza ikoranabuhanga rya infrared, ahubwo binadufasha gusobanukirwa neza ikoranabuhanga ry'itumanaho ridafite infrared.
