Kodi mukudziwa mfundo yoyendetsera TV yakutali?

Ngakhale kutukuka kwachangu kwa zida zanzeru monga mafoni am'manja, TV ikadali chida chofunikira chamagetsi kwa mabanja, ndipo zowongolera zakutali, monga zida zowongolera za TV, zimalola anthu kusintha mawayilesi a TV popanda zovuta.
Ngakhale kutukuka kwachangu kwa zida zanzeru monga mafoni am'manja, TV ikadali chida chofunikira chamagetsi cha mabanja.Monga zida zowongolera za TV, anthu amatha kusintha matchanelo a TV mosavuta.Ndiye kodi remote control imazindikira bwanji zakutali za TV?
Ndi kupita patsogolo kwaukadaulo, mitundu ya zowongolera zopanda zingwe zikukulanso.Nthawi zambiri pamakhala mitundu iwiri, imodzi ndi infrared remote control, inayo ndi ma radio shake control mode.M'moyo wathu watsiku ndi tsiku, njira yomwe imagwiritsidwa ntchito kwambiri ndi infrared remote control mode.Kutengera chiwongolero chakutali cha TV monga chitsanzo, tiyeni tikambirane za mfundo zake zogwirira ntchito.
Dongosolo loyang'anira kutali nthawi zambiri limapangidwa ndi ma transmitter (remote controller), receiver and central processing unit (CPU), momwe wolandila ndi CPU amakhala pa TV.Woyang'anira kutali wa TV wamba amagwiritsa ntchito kuwala kwa infrared ndi kutalika kwa ma microns 0.76 ~ 1.5 kuti atulutse zidziwitso zowongolera.Mtunda wake wogwira ntchito ndi 0 ~ 6 mamita okha ndipo umafalikira molunjika.Mu gawo lamkati la chowongolera chakutali, chogwirizana ndi fungulo lililonse pa chowongolera chakutali, dera lamkati limatenga njira yolembera kuti igwirizane nayo.Pamene fungulo linalake likuphwanyidwa, dera linalake la dera limalumikizidwa, ndipo chip chimatha kuzindikira kuti ndi dera liti lomwe likulumikizidwa ndikuweruza fungulo liti.Kenako, chipcho chidzatumiza chizindikiro chotsatizana ndi fungulo.Pambuyo pakukulitsa ndikusintha, chizindikirocho chimatumizidwa ku diode yotulutsa kuwala ndikusinthidwa kukhala siginecha ya infrared kuti iwonekere kunja.Pambuyo polandira chizindikiro cha infrared, wolandila TV amatsitsa ndikuwongolera kuti abwezeretse chizindikiro chowongolera, ndikutumiza chizindikirocho kugawo lapakati lopangira, lomwe limagwira ntchito zofananira monga kusintha ma tchanelo.Chifukwa chake, timazindikira ntchito yakutali ya TV.
Kuwongolera kwakutali kwa infrared kuli ndi zabwino zambiri.Choyamba, mtengo wa infrared remote control ndi wotsika komanso wosavuta kuvomerezedwa ndi anthu.Kachiwiri, kuwongolera kwakutali kwa infrared sikungakhudze malo ozungulira ndipo sikusokoneza zida zina zamagetsi.Ngakhale zida zapakhomo m'nyumba zosiyanasiyana, titha kugwiritsa ntchito mtundu womwewo wakutali, chifukwa chowongolera chakutali cha infrared sichingadutse khoma, kotero sipadzakhala kusokoneza.Potsirizira pake, njira yoyendetsera dera lakutali ndiyosavuta, kawirikawiri tikhoza kuigwiritsa ntchito popanda kusokoneza, bola ngati tigwirizanitsa molondola malinga ndi dera lomwe latchulidwa.Chifukwa chake, kuwongolera kwakutali kwa infrared kwagwiritsidwa ntchito kwambiri pazida zathu zapakhomo.
Kubwera kwa nthawi yanzeru, ntchito za TV zikukula mosiyanasiyana, koma kuwongolera kwakutali kumakhala kosavuta.Palibe mabatani ochulukirapo m'mbuyomu, ndipo mawonekedwe ake ndiamunthu.Komabe, ziribe kanthu momwe zimakhalira, chiwongolero chakutali, monga chida chofunikira chamagetsi cholumikizirana ndi makompyuta a anthu, chiyenera kukhala chosasinthika.
