Kodi mawaya abwino ndi oyipa mu chingwe cha USB ndi ati

Mkati mwa "universal serial bus" kapena USB, muli mawaya anayi, omwe nthawi zambiri amakhala ofiira, obiriwira, oyera, ndi akuda. Iliyonse mwa mawayawa ili ndi chizindikiro chofananira kapena ntchito. Kuzindikira ma terminals abwino ndi oyipa ndikofunikira mukamagwira nawo ntchito.

Ngakhale pali mawaya awiri abwino ndi oyipa palimodzi, iliyonse ili ndi ntchito yosiyana.

M'nkhaniyi, tikhala pa mawayawa mwatsatanetsatane.

Kodi mawaya anayi aliwonse a chingwe cha USB amachita chiyani?

Imodzi mwamadoko omwe amagwiritsidwa ntchito kwambiri komanso njira zoyankhulirana pazida ndi USB kapena Universal Serial Bus. Cholinga cha USB chinali kuyang'anira madoko omwe zida zamakompyuta monga osindikiza ndi kiyibodi zidalumikizidwa. Mutha kupeza zosankha zamadoko pazida zamagetsi monga mafoni am'manja, masikaniro, makamera, ndi owongolera masewera omwe amalumikizana ndi olandila. (1)

Mukatsegula chingwe cha USB, mumatha kuona mitundu inayi ya mawaya a USB: ofiira ndi akuda kuti apange mphamvu, zoyera ndi zobiriwira za deta, ndi zina zotero. Waya wabwino wonyamula 5 volts ndi wofiira; waya woipa, womwe nthawi zambiri umatchedwa waya wapansi, ndi wakuda. Pali chithunzi cha pinout cha mtundu uliwonse wa kulumikizana kwa USB; izi ndi timizere ting'onoting'ono tachitsulo mkati mwa cholumikizira chomwe chimagwiritsidwa ntchito kulumikiza chingwe chilichonse ndi ntchito zake.

Mitundu ya chingwe cha USB ndi zomwe zikutanthauza

Waya mtundu	chizindikiro
Waya wofiira	Chingwe chamagetsi chabwino chimapereka 5 volts DC.
waya wakuda	Waya wamagetsi wapansi kapena woipa.
Waya woyera	Positive data waya.
Waya wobiriwira	Negative data waya.

Zina zamtundu wa waya wa USB

M'zingwe zina za USB, mutha kupeza mitundu yosiyanasiyana yamawaya, kuphatikiza lalanje, buluu, yoyera, ndi yobiriwira. 

Tanthauzo la mawaya abwino kapena oipa mu mtundu uwu wa mtundu ndi wosiyana. Pankhaniyi, muyenera kuyang'ana tebulo ili m'munsimu:

Waya mtundu	chizindikiro
Waya walalanje	Chingwe chamagetsi chabwino chimapereka mphamvu ya 5 volt DC.
Waya woyera	Waya wamagetsi wapansi kapena woipa.
waya wabuluu	Negative data waya.
Waya wobiriwira	Positive data waya.

Mitundu ya zingwe za USB

Pali mitundu yosiyanasiyana ya USB, ndipo protocol ya chingwe cha USB imatsimikizira momwe ingasinthire deta mwachangu. Mwachitsanzo, doko la USB 2.0 limatha kusamutsa deta mpaka 480 Mbps, pomwe doko la USB 3.1 Gen 2 limatha kusamutsa deta pa 10 Mbps. Mutha kugwiritsa ntchito tebulo ili m'munsimu kuti mumvetsetse kuthamanga ndi mawonekedwe amtundu uliwonse wa USB:

Mtundu wa USB	Kodi imatha kusewera makanema?	Kodi ikhoza kupereka mphamvu?	Mtengo wamtengo
USB 1.1	No	No	12 Mbps.
USB 2.0	No	kuti	480 Mbps.
USB 3.0	kuti	kuti	5 Gbps
USB 3.1	kuti	kuti	10 Gbps

Mafunso ofunsidwa kawirikawiri

Nchiyani chimapangitsa USB-C kukhala yosiyana ndi USB wamba?

Poyerekeza ndi USB-A, yomwe imatha kugwira mpaka 2.5W ndi 5V, USB-C tsopano imatha kugwira bwino 100W ndi 20V pazida zazikulu. Kulipiritsa - makamaka kachipangizo ka USB komwe kamathandizira ma laputopu ndikulipiritsa zida zina nthawi imodzi - ndi imodzi mwazinthu zothandiza.

Kodi mizere yobiriwira ndi yoyera imakhala yofunika?

Mawaya a positive-negative ndi zingwe zofunika kwambiri. Kudziwa mtundu wamtundu wa mabwalo amagetsiwa ndikofunikira chifukwa ndikofunikira pakuwongolera zida zanu.

Kodi chingwe cha USB chingagawidwe ndikulumikizidwa?

Mukhoza kupanga anu USB zingwe ndi kudula ndi splicing zingwe alipo kutalika ndi cholumikizira mtundu mukufuna. Zida zokhazo zomwe zimafunikira pa njirayi ndi zodula mawaya ndi tepi yamagetsi, ngakhale chitsulo chosungunuka ndi kutentha kwachubu chingagwiritsidwe ntchito kupititsa patsogolo ubwino wa chingwe.

Onani zina mwazolemba zathu pansipa.

• Momwe mungasiyanitsire waya wolakwika kuchokera ku zabwino
• waya woyera zabwino kapena zoipa
• Kodi waya wa buluu pa fan fan ndi chiyani
