Uhlelo Lokushaja Okusheshayo Olusekelwe Ekulethweni Kwamandla e-USB
Ubuchwepheshe buyisici esiqhubeka nokuthuthuka ngokushesha kulesi sikhathi sanamuhla. Esinye sezitayela zakamuva ze-elekthronikhi ukushaja okusheshayo, okuhlose ukunciphisa isikhathi esidingekayo ukuze kushajwe amadivayisi kagesi. Indinganiso eyodwa evelele kulesi sigaba yi-USB Power Delivery (USB PD). Lesi sihloko sizoxoxa ngokuningiliziwe ngohlelo lokushaja okusheshayo olusekelwe ku-USB Power Delivery, okuhlanganisa nendlela olusebenza ngayo, izinzuzo zalo, ukusetshenziswa kwalo, kanye nomthelela walo esikhathini esizayo.
Isingeniso Sokulethwa Kwamandla E-USB
Ukulethwa Kwamandla e-USB kuyindinganiso ethuthukiswe ukuthuthukisa amakhono okushaja nokudlulisa idatha ngezintambo ze-USB. I-USB PD ivumela amadivayisi ukuthi ashaje ngamaza aphezulu kanye nama-voltage kunezindinganiso ze-USB zangaphambilini.
Umlando Wokulethwa Kwamandla E-USB
Izinga le-USB liye lathuthuka kaningana selokhu lasungulwa okokuqala ngo-1996. Ukulethwa Kwamandla e-USB kwaqala ukuthola ukunakwa lapho kwethulwa njengengxenye yencazelo ye-USB 3.1 ngo-2012. Imininingwane ye-USB 3.1 ivumela ukulethwa kwamandla kufika ku-100 watts, okuwumehluko omkhulu ezindinganisweni zangaphambilini ezazingaphatha kuphela kufika ku-2,5 watts (ku-USB 2.0) noma ku-4,5 watts (ku-USB 3.0).
Ngo-2014, imininingwane ye-USB PD yabuyekezwa futhi yabuyekezwa njengengxenye yendinganiso ye-USB Type-C okwakulindeleke ukuthi ibe yisisombululo esijwayelekile sokushaja amadivayisi kagesi afana nama-smartphone, amaphilisi, nama-laptop.
Indlela Ukulethwa Kwamandla E-USB Okusebenza Ngayo
Ukulethwa Kwamandla e-USB kusebenza ngokuvumela amadivayisi ayisekelayo ukuthi asebenzisane futhi axoxisane ngokuthi adinga noma anganikeza amandla angakanani. Isibonelo, uma uxhuma i-smartphone enikwe amandla e-USB PD kushaja enikwe amandla e-USB PD, ukuxhumana kwedatha kwenzeka phakathi kwamadivayisi amabili.
Lokhu kuxhumana kwenziwa ngephinikhodi ye-CC (Configuration Channel) echwebeni le-USB Type-C. Ngokusebenzisa le protocol yokuxhumana, idivayisi izonquma iphrofayili yamandla efanele ngokusekelwe ku-voltage kanye nogesi ishaja engawunikeza kanye nezidingo zedivayisi eshajwayo.
Iphrofayili Yamandla ku-USB PD
Esinye sezici ezijabulisa kakhulu zokulethwa kwamandla e-USB ukuguquguquka okunikezayo kumaphrofayili wamandla. Leli zinga livumela ububanzi obukhulu bamaphrofayili wamandla angasetshenziswa:
– 5V @ 2A (10W)
– 9V @ 3A (27W)
– 15V @ 3A (45W)
– 20V @ 5A (100W)
Ngala maphrofayili ahlukahlukene wamandla, i-USB PD ayiyona nje ikhambi lamadivayisi amancane afana nama-smartphone namathebulethi, kodwa futhi ingasetshenziswa ukushaja ama-laptop noma amadivayisi adinga amandla aphezulu.
Isigaba Sokuxoxisana
Ngesikhathi sesigaba sokuxoxisana, idivayisi eshajwayo izocela amandla kusuka kushaja ngokusekelwe kumaphrofayili atholakalayo. Ishaja, nayo, izophendula futhi inikeze amandla ngokwesicelo. Le nqubo iyenzeka ngokuzenzakalela futhi ithatha isikhathi esincane kakhulu, ngokuvamile imizuzwana embalwa nje.
Izinzuzo Zokulethwa Kwamandla E-USB
Njengoba ukusetshenziswa kwamadivayisi aphathekayo kukhula, isidingo sokushaja okusheshayo nokusebenza kahle sesibaluleke kakhulu. Nazi ezinye zezinzuzo ezibalulekile zokulethwa kwamandla e-USB:
Ukushaja Okusheshayo
Enye yezinzuzo ezinkulu ze-USB PD yikhono layo lokushaja amadivayisi ngokushesha okukhulu. Njengoba amandla ephuma kufika ku-100 watts, izikhathi zokushaja zingancishiswa kakhulu uma kuqhathaniswa nobuchwepheshe bokushaja bendabuko.
Ukuzivumelanisa nezimo okuphezulu
I-USB PD yakhelwe ukuba iguquguquke kakhulu futhi isebenziseke ngezindlela eziningi. Ingasetshenziswa ukushaja izinhlobo eziningi zamadivayisi anobukhulu obuhlukahlukene nezidingo zamandla. Kusukela kuma-smartphone kuya kuma-laptop, i-USB PD ingakwazi ukusingatha konke.
I-Universal kanye ne-Standard
Ngenxa yokuthi i-USB PD iyingxenye yencazelo ye-USB Type-C, kulindeleke ukuthi ibe yindinganiso evamile yokushaja. Lokhu kunciphisa isidingo sezintambo eziningi namashaja amadivayisi ahlukene, okusindisa isikhala nemali kakhulu.
Ukusebenza Kwamandla
I-USB PD nayo igcina amandla kahle. Ngokunciphisa izikhathi zokushaja nokuqinisekisa ukuthi amandla alethwayo ahambisana nezidingo zedivayisi, i-USB PD isiza ukonga amandla nokunciphisa imfucuza.
Ukusetshenziswa Nokusetshenziswa
Njengoba i-USB PD ithandwa kakhulu, amadivayisi amaningi kanye namashaja asekela le nqubo aqala ukuvela emakethe. Ezinye izibonelo zokusetshenziswa zifaka:
Ama-laptop nama-ultrabook
Abakhiqizi abaningi bama-laptop manje bafaka imbobo ye-USB Type-C esekela i-USB PD njengembobo yokushaja kuphela. Lokhu akunciphisi nje kuphela ukuthembela kumashaja angokwakho kodwa futhi kuvumela ama-laptop ukuthi ashajwe ngebhange lamandla elisebenzisa i-USB PD noma ishaja yodonga.
smartphone
Ama-smartphone amaningi ahamba phambili manje asekela ubuchwepheshe be-USB PD bokushaja okusheshayo. Lokhu kuvumela abasebenzisi ukuthi bajabulele izikhathi zokushaja ezimfushane nezilula kakhudlwana.
Izesekeli Namabhange Amandla
Amabhange kagesi asekela i-USB PD aya ngokuya evame kakhulu, enikeza ikhambi lokushaja eliphathekayo elisheshayo nelisebenza kahle kakhulu kumadivayisi ahlukahlukene.
Umthelela Wesikhathi Esizayo
Njengoba kusetshenziswa kakhulu, ukulethwa kwamandla e-USB cishe kuzoba yindinganiso yokushaja esikhathini esizayo. Lokhu kungaba nemiphumela emihle eminingana:
Ukunciphisa Imfucuza Kagesi
Ngokususa isidingo samashaja amaningi kanye nezintambo, i-USB PD inamandla okunciphisa kakhulu imfucuza ye-e. Lesi yisinyathelo esihle sobuchwepheshe obunobungani nemvelo.
Ukungaguquguquki kanye Nenduduzo
Ukusebenzisa indinganiso eyodwa evamile kuwo wonke amadivayisi kuzokwandisa ukulula kanye nokuvumelana kwabathengi. Asikho isidingo sokuphatha amashaja amaningi amadivayisi ahlukene lapho usohambweni.
Ukusungula Izinto Ezintsha Nokuthuthukiswa Okuqhubekayo
Ukwamukelwa kabanzi kwe-USB PD nakho kuholela emisha kwezobuchwepheshe bebhethri nokushaja. Abakhiqizi bamadivayisi kagesi bazokhuthazwa ngokwengeziwe ukuthi bakhe amadivayisi anezikhathi zokushaja ezisheshayo nezisebenza kahle.
Isiphetho
Ukulethwa Kwamandla e-USB kushintshe indlela esishaja ngayo amadivayisi ethu kagesi. Ngenxa yokuguquguquka kwayo, ukusebenza kahle, kanye nekhono lokuletha amandla amakhulu, le ndinganiso isibe yisisombululo esilindelwe kakhulu emhlabeni wonke. Njengoba lobu buchwepheshe buqala ukwamukelwa kabanzi, singalindela amadivayisi kagesi ahlala isikhathi eside, asebenza kahle, futhi anobungani nemvelo esikhathini esizayo. Kungakhathaliseki ukuthi ungumsebenzisi we-smartphone noma i-laptop, ikhono lokushaja amadivayisi akho ngokushesha nangokusebenza kahle ngokuqinisekile liyinzuzo ebalulekile okungafanele inganakwa.
