Dongosolo Lochapira Mwachangu Lochokera ku Kutumiza Mphamvu ya USB
Ukadaulo ndi mbali imodzi yomwe ikupitilira kukula mofulumira m'nthawi yamakono ino. Chimodzi mwa zinthu zamakono zamagetsi ndi kuyitanitsa mwachangu, komwe cholinga chake ndi kuchepetsa nthawi yofunikira kuti muyikenso zida zamagetsi. Muyezo umodzi wodziwika bwino m'gululi ndi USB Power Delivery (USB PD). Nkhaniyi ikambirana mwatsatanetsatane njira yoyitanitsa mwachangu yochokera ku USB Power Delivery, kuphatikizapo momwe imagwirira ntchito, ubwino wake, momwe imagwirira ntchito, komanso zotsatira zake mtsogolo.
Chiyambi cha Kutumiza Mphamvu ya USB
USB Power Delivery ndi muyezo wopangidwa kuti uthandize kutha kuyatsa ndi kusamutsa deta kudzera pa zingwe za USB. USB PD imalola zipangizo kutha kuyatsa pamagetsi ndi ma voltage apamwamba kuposa miyezo yakale ya USB.
Mbiri ya Kutumiza Mphamvu ya USB
Muyezo wa USB wasintha kangapo kuyambira pomwe unayamba kugwiritsidwa ntchito mu 1996. USB Power Delivery inayamba kutchuka pamene inayambitsidwa ngati gawo la specification ya USB 3.1 mu 2012. Specification ya USB 3.1 imalola kuperekedwa kwa mphamvu mpaka ma watts 100, zomwe ndi kusiyana kwakukulu kuchokera ku miyezo yakale yomwe inkatha kugwira ntchito mpaka ma watts 2,5 (pa USB 2.0) kapena ma watts 4,5 (pa USB 3.0).
Mu 2014, mfundo za USB PD zinasinthidwa ndi kusinthidwa ngati gawo la muyezo wa USB Type-C womwe unkayembekezeredwa kukhala yankho lodziwika bwino pakuchaja zida zamagetsi monga mafoni, mapiritsi, ndi ma laputopu.
Momwe Kutumiza Mphamvu ya USB Kumagwirira Ntchito
Kutumiza Mphamvu ya USB kumagwira ntchito polola zipangizo zomwe zimathandizira kuti zigwirizane ndikukambirana za kuchuluka kwa mphamvu zomwe zimafunikira kapena zomwe zingapereke. Mwachitsanzo, mukalumikiza foni yam'manja yolumikizidwa ndi USB PD ku chojambulira cholumikizidwa ndi USB PD, kulumikizana kwa data kumachitika pakati pa zipangizo ziwirizi.
Kulankhulana kumeneku kumachitika kudzera mu CC (Configuration Channel) pin pa USB Type-C port. Pogwiritsa ntchito protocol yolumikizirana iyi, chipangizochi chimasankha mbiri yoyenera yamagetsi kutengera voltage ndi mphamvu yomwe charger ingapereke komanso zosowa za chipangizo chomwe chikuchajidwa.
Mbiri Yamagetsi mu USB PD
Chimodzi mwa zinthu zosangalatsa kwambiri pa USB Power Delivery ndi kusinthasintha komwe kumapereka mu ma profiles amphamvu. Muyezo uwu umalola ma profiles amphamvu osiyanasiyana omwe angagwiritsidwe ntchito:
– 5V @ 2A (10W)
– 9V @ 3A (27W)
– 15V @ 3A (45W)
– 20V @ 5A (100W)
Ndi ma profiles osiyanasiyana amagetsi awa, USB PD si yankho la zipangizo zazing'ono monga mafoni ndi mapiritsi okha, komanso ingagwiritsidwe ntchito pochajitsa ma laputopu kapena zipangizo zomwe zimafuna mphamvu zambiri.
Gawo Lokambirana
Pa nthawi yokambirana, chipangizo chomwe chikuchajidwa chidzapempha mphamvu kuchokera ku charger kutengera ma profiles omwe alipo. Charger, nayonso, idzayankha ndikupereka mphamvu malinga ndi pempho. Njirayi imachitika yokha ndipo imatenga nthawi yochepa kwambiri, nthawi zambiri masekondi ochepa chabe.
Ubwino Wotumizira Mphamvu ya USB
Chifukwa cha kuchuluka kwa kugwiritsa ntchito zipangizo zonyamulika, kufunika kochaja mwachangu komanso moyenera kwakhala kofunika kwambiri. Nazi zina mwa zabwino zazikulu za USB Power Delivery:
Kuchaja Mofulumira
Chimodzi mwa ubwino waukulu wa USB PD ndi kuthekera kwake kuchaja zipangizo mwachangu kwambiri. Ndi mphamvu zotulutsa mphamvu zokwana ma watts 100, nthawi yochaja imatha kuchepetsedwa kwambiri poyerekeza ndi ukadaulo wachikhalidwe wochaja.
Kusinthasintha Kwambiri
USB PD yapangidwa kuti ikhale yosinthasintha komanso yosinthasintha kwambiri. Ingagwiritsidwe ntchito pochaja zipangizo zosiyanasiyana za kukula kosiyanasiyana komanso mphamvu zosiyanasiyana. Kuyambira mafoni a m'manja mpaka ma laputopu, USB PD imatha kugwira ntchito yonse.
Universal ndi Standard
Popeza USB PD ndi gawo la USB Type-C specifications, ikuyembekezeka kukhala muyezo wodziwika bwino wolipirira. Izi zimachepetsa kufunikira kwa zingwe ndi ma charger angapo pazida zosiyanasiyana, zomwe zimasunga malo ndi ndalama zambiri.
Mphamvu Mwachangu
USB PD imathandizanso kuti magetsi azigwiritsidwa ntchito moyenera. Mwa kuchepetsa nthawi yochajira ndikuonetsetsa kuti mphamvu zomwe zaperekedwa zikugwirizana ndi zosowa za chipangizocho, USB PD imathandiza kusunga mphamvu ndikuchepetsa kuwononga.
Kukhazikitsa ndi Kugwiritsa Ntchito
Pamene USB PD ikutchuka kwambiri, zipangizo zambiri ndi ma charger othandizira muyezo uwu akuyamba kuonekera pamsika. Zitsanzo zina za zomwe zagwiritsidwa ntchito ndi izi:
Malaputopu ndi Ma Ultrabook
Opanga ma laputopu ambiri tsopano ali ndi doko la USB Type-C lomwe limathandizira USB PD ngati doko lokhalo loyatsira. Izi sizimangochepetsa kudalira ma charger enieni komanso zimathandiza kuti ma laputopu azichajidwa kudzera mu banki yamagetsi yolumikizidwa ndi USB PD kapena chochaji cha pakhoma.
yamakono
Mafoni ambiri apamwamba tsopano amathandizira ukadaulo wa USB PD kuti azitha kuyatsa mwachangu. Izi zimathandiza ogwiritsa ntchito kusangalala ndi nthawi yochepa komanso yosavuta yoyatsira.
Zowonjezera ndi Mabanki Amagetsi
Mabanki amagetsi omwe amathandizira USB PD akuchulukirachulukira, akupereka njira yofulumira komanso yothandiza kwambiri yolipirira zinthu zonyamulika pazida zosiyanasiyana.
Zotsatira za Mtsogolo
Popeza kugwiritsa ntchito mphamvu ya USB Power Delivery kukuchulukirachulukira, mwina kudzakhala muyezo woti muyambe kuigwiritsa ntchito mtsogolo. Izi zitha kukhala ndi zotsatira zabwino zingapo:
Kuchepetsa Zinyalala Zamagetsi
Mwa kuthetsa kufunikira kwa ma charger ndi zingwe zingapo, USB PD ili ndi kuthekera kochepetsa kwambiri zinyalala zamagetsi. Iyi ndi sitepe yabwino yopita ku ukadaulo wosawononga chilengedwe.
Kusasinthasintha ndi Chitonthozo
Kugwiritsa ntchito muyezo umodzi wokha pa zipangizo zonse kudzawonjezera kusavuta ndi kusinthasintha kwa ogula. Palibe chifukwa chonyamula ma charger angapo pa zipangizo zosiyanasiyana paulendo.
Zatsopano ndi Chitukuko Chowonjezereka
Kugwiritsa ntchito kwambiri USB PD kukupangitsanso kuti pakhale luso lamakono pakugwiritsa ntchito mabatire ndi ukadaulo wochaja. Opanga zida zamagetsi adzalimbikitsidwanso kuti apange zida zomwe zimakhala ndi nthawi yochaja mwachangu komanso moyenera.
Mapeto
USB Power Delivery yasintha momwe timachajira zipangizo zathu zamagetsi. Chifukwa cha kusinthasintha kwake, kugwira ntchito bwino, komanso kuthekera kopereka mphamvu zambiri, muyezo uwu wakhala yankho loyembekezeredwa kwambiri padziko lonse lapansi. Pamene ukadaulo uwu ukugwiritsidwa ntchito kwambiri, tikuyembekezera zipangizo zamagetsi zolimba, zogwira ntchito bwino, komanso zosawononga chilengedwe mtsogolo. Kaya ndinu wogwiritsa ntchito foni yam'manja kapena laputopu, kuthekera kochajira zipangizo zanu mwachangu komanso moyenera ndi mwayi waukulu womwe suyenera kunyalanyazidwa.
