Sisitimu Yekuchaja Inokurumidza yeUSB Power Delivery-Based
Tekinoroji chimwe chezvinhu zviri kuramba zvichikura nekukurumidza munguva ino yemazuva ano. Imwe yenzira dzemazuva ano dzemagetsi kuchaja nekukurumidza, iyo ine chinangwa chekuderedza nguva inodiwa kuti uchajezve zvishandiso zvemagetsi. Imwe yenzira dzakakurumbira muchikamu ichi iUSB Power Delivery (USB PD). Chinyorwa chino chichakurukura zvakadzama nezve USB Power Delivery-based fast charging system, kusanganisira mashandiro ayo, zvakanakira zvayo, mashandiro ayo, uye mhedzisiro yayo mune ramangwana.
Nhanganyaya yekutumirwa kwemagetsi eUSB
USB Power Delivery chiyero chakagadzirwa kuti chivandudze kugona kwekuchaja nekutumira data kuburikidza netambo dzeUSB. USB PD inobvumira michina kuti ichaje pamagetsi nemavoltage akakwira kupfuura zvaitarisirwa kare zveUSB.
Nhoroondo yekutumira simba re USB
Chiyero cheUSB chakavandudzwa kakawanda kubva pakatanga kushandiswa muna 1996. USB Power Delivery yakatanga kukwezva vanhu vakawanda payakatangwa sechikamu chezviyero zveUSB 3.1 muna 2012. Zviyero zveUSB 3.1 zvinobvumira simba remagetsi kusvika ku100 watts, musiyano mukuru kubva pane zvakamboshandiswa kare zvaingokwanisa kushanda kusvika ku2,5 watts (paUSB 2.0) kana 4,5 watts (paUSB 3.0).
Muna 2014, zvirevo zveUSB PD zvakagadziriswazve uye zvakagadziridzwa sechikamu cheUSB Type-C standard iyo yaitarisirwa kuva mhinduro yepasi rose yekuchaja zvishandiso zvemagetsi zvakaita semafoni, mapiritsi, uye malaptop.
Mashandiro Anoita Kutumira Simba re USB
Kuendeswa kweMagetsi eUSB kunoshanda nekubvumira michina inoitsigira kuti itaurirane uye itaurirane pamusoro pekuti vanoda kana kuti vanogona kupa simba rakawanda sei. Semuenzaniso, kana ukabatanidza foni ine USB PD kune charger ine USB PD, kutaurirana kwedata kunoitika pakati pemidziyo miviri iyi.
Kutaurirana uku kunoitwa kuburikidza neCC (Configuration Channel) pin iri paUSB Type-C port. Uchishandisa iyi protocol yekutaurirana, mudziyo uchasarudza simba rakakodzera zvichienderana nevoltage nemagetsi zvinogona kupihwa nechaja pamwe nezvinodiwa nemudziyo uri kuchajwa.
Simba reProfile muUSB PD
Chimwe chezvinhu zvinonakidza paUSB Power Delivery ndiko kushanduka kwazvinoita mumaprofile emagetsi. Iyi standard inobvumira akasiyana-siyana emaprofile emagetsi anoshandiswa:
– 5V @ 2A (10W)
– 9V @ 3A (27W)
– 15V @ 3A (45W)
– 20V @ 5A (100W)
Nemaprofayiro aya emagetsi akasiyana-siyana, USB PD haisi mhinduro chete yemidziyo midiki yakaita semafoni nemapiritsi, asi inogonawo kushandiswa kuchaja malaptop kana michina inoda simba rakawanda.
Chikamu Chekutaurirana
Munguva yekutaurirana, mudziyo uri kuchajwa uchakumbira simba kubva kucharger zvichienderana nemaprofile aripo. Charger, inozopindura yopa simba zvichienderana nechikumbiro. Maitiro aya anongoerekana aitika uye anotora nguva shoma, kazhinji masekondi mashoma chete.
Mabhenefiti ekutumira simba re USB
Nekuwedzera kwekushandiswa kwemidziyo inotakurika, kukosha kwekuchaja nekukurumidza uye nemazvo kwave kuri kuwedzera kukosha. Heano mamwe mabhenefiti makuru eUSB Power Delivery:
Kuchaja nekukurumidza
Chimwe chezvakanakira zvikuru zveUSB PD kugona kwayo kuchaja zvishandiso nekukurumidza. Nesimba rinobuda kusvika ku100 watts, nguva yekuchaja inogona kuderedzwa zvakanyanya kana tichienzanisa netekinoroji yekuchaja yechinyakare.
Kuchinjika Kwakanyanya
USB PD yakagadzirwa kuti ive inochinjika uye inokwanisa kushandiswa pakushandisa simba rakawanda. Inogona kushandiswa kuchaja michina yakasiyana-siyana ine saizi dzakasiyana uye simba rinodiwa. Kubva kumafoni kusvika kumalaptop, USB PD inogona kushanda nayo yese.
Yese uye Yakajairwa
Nekuti USB PD iri chikamu chemhando yeUSB Type-C, inotarisirwa kuve chiyero chepasi rose chekuchaja. Izvi zvinoderedza kudiwa kwetambo dzakawanda nemachaja emidziyo yakasiyana, zvichichengetedza nzvimbo nemari zvakanyanya.
Efisiensi Energi
USB PD inoshandawo zvakanaka pakushandisa simba. Nekuderedza nguva yekuchaja uye kuona kuti simba rinopihwa rinoenderana nezvinodiwa nemudziyo, USB PD inobatsira kuchengetedza simba uye kuderedza marara.
Kuitwa uye Kushandiswa
Sezvo USB PD yava kufarirwa zvakanyanya, zvishandiso zvakawanda nemachaja anotsigira chiyero ichi ari kutanga kuoneka pamusika. Mimwe mienzaniso yekushandiswa kwayo inosanganisira:
Malaptop uye Ultrabooks
Vagadziri vazhinji vemalaptop vava kushandisa USB Type-C port inotsigira USB PD senzvimbo yekuchaja chete. Izvi hazvingoderedzi kuvimba nemachaja ega asiwo zvinobvumira malaptop kuchaja kuburikidza ne USB PD-enabled power bank kana wall charger.
smartphone
Mafoni mazhinji emhando yepamusoro ikozvino anotsigira tekinoroji yeUSB PD yekuchaja nekukurumidza. Izvi zvinobvumira vashandisi kunakidzwa nenguva pfupi uye dziri nyore dzekuchaja.
Zvishongedzo uye Mabhangi Emagetsi
Mabhangi emagetsi anotsigira USB PD ari kuwanda, zvichipa nzira yekuchaja inotakurika nekukurumidza uye inoshanda zvakanyanya kune akasiyana-siyana maturusi.
Mhedzisiro Yeramangwana
Nekuwedzera kwekushandiswa, USB Power Delivery ingangove ndiyo nzira yekuchaja mune ramangwana. Izvi zvinogona kuva nemigumisiro yakanaka yakati wandei:
Kuderedza Marara Emagetsi
Nekubvisa kudiwa kwemachaja netambo dzakawanda, USB PD ine mukana wekuderedza zvakanyanya marara emagetsi. Iri idanho rakanaka rekugadzira tekinoroji isingakuvadzi nharaunda.
Kugadzikana uye Kunyaradzwa
Kushandisa mwero mumwe chete wezvinhu zvese zvinoshandiswa kunowedzera nyore uye kugara kwenguva refu kune vatengi. Hapana chikonzero chekutakura machaja akawanda ezvishandiso zvakasiyana paunenge uchifamba.
Kugadzira Zvinhu Zvitsva uye Kufambira Mberi
Kushandiswa kwakapararira kweUSB PD kuri kukurudzirawo hunyanzvi muhunyanzvi hwemabhatiri nekuchaja. Vagadziri vemidziyo yemagetsi vachakurudzirwa zvakare kugadzira michina ine nguva yekuchaja inokurumidza uye inoshanda.
Mhedziso
Kuendeswa kwemagetsi eUSB kwakachinja nzira yatinochaja nayo midziyo yedu yemagetsi. Nekuchinjika kwayo, kushanda kwayo zvakanaka, uye kugona kwayo kupa simba rakawanda, chiyero ichi chave mhinduro inotarisirwa zvikuru kune vese. Sezvo tekinoroji iyi ichinyanya kushandiswa, tinogona kutarisira midziyo yemagetsi inogara kwenguva refu, inoshanda zvakanaka, uye isingakuvadzi nharaunda mune ramangwana. Kunyangwe uri mushandisi wefoni mbozha kana laptop, kugona kuchaja midziyo yako nekukurumidza uye zvine hungwaru zvechokwadi ibhenefiti huru isingafaniri kufuratirwa.
