Ngakhale kutukuka kwachangu kwa zida zanzeru monga mafoni am'manja, TV ikadali chida chofunikira chamagetsi cha 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 ali pa TV.Woyang'anira kutali wa TV amagwiritsa ntchito cheza cha infrared chokhala ndi kutalika kwa ma microns 0.76 ~ 1.5 kutulutsa chidziwitso chowongolera.Mtunda wake wogwira ntchito ndi 0 ~ 6 mamita okha ndipo umafalikira molunjika.Mu gawo lamkati la chowongolera chakutali, chogwirizana ndi kiyi iliyonse pa chowongolera chakutali, dera lamkati limatenga njira yolembera kuti igwirizane nayo.Pamene fungulo linalake likuphwanyidwa, dera linalake mu dera limalumikizidwa, ndipo chip chimatha kuzindikira kuti ndi dera liti lomwe likulumikizidwa ndikuweruza fungulo liti.Kenako, chipcho chidzatumiza chizindikiro chotsatizana ndi fungulo.Pambuyo pakukulitsa ndi kusinthasintha, chizindikirocho chimatumizidwa ku diode yotulutsa kuwala ndikusinthidwa kukhala chizindikiro cha infrared kuti chiwalire kunja.Pambuyo polandira chizindikiro cha infrared, wolandila TV amatsitsa ndikuwongolera kuti apezenso chizindikiro chowongolera, ndikutumiza chizindikirocho kugawo lapakati lopangira, lomwe limagwira ntchito zofananira monga kusintha mayendedwe.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 ambiri m'mbuyomu, ndipo mawonekedwe ake ndiamunthu.Komabe, ziribe kanthu momwe zimakhalira, chiwongolero chakutali, monga chida chofunikira chamagetsi pakugwiritsa ntchito makompyuta a anthu, chiyenera kukhala chosasinthika.
