Ma garanaysaa waxa PD yahay?Magaca buuxa ee PD waa Delivery Power, kaas oo ah hab-maamuuska dallacaadda midaysan oo ay soo saartay Ururka USB si loo mideeyo xiriiriyeyaasha iyada oo loo marayo USB Type C. Sida habboon, ilaa iyo inta qalabku taageerayo PD, dhib ma leh haddii aad tahay buug xusuus-qor ah, tablet ama taleefan gacanta ah. , waxaad isticmaali kartaa hal borotokoolka dallacaadda.USB TypeC ilaa fiilada TypeC iyo dallad PD ah ayaa loo isticmaalaa in lagu dallaco.
1. Fikradda aasaasiga ah ee Dallacaadda
Si aan marka hore u fahamno PD, waa in aan marka hore fahamnaa in xawaaraha ku dallacadu uu la xiriiro korontada, awoodduna ay la xiriirto danab iyo hadda, tanina waxay ku xiran tahay qaacidada korontada.
P= V* I
Markaa haddii aad rabto in aad dhakhso u dalacdo, awooddu waa in ay sarraysaa.Si aad u kordhiso tamarta, waxaad kordhin kartaa tamarta, ama waxaad kordhin kartaa hadda.Laakiin ka hor ma jiro borotokoolka dallacaadda PD, kan ugu caansanUSB2.0Heerarka ayaa qeexaya in korantadu ay tahay 5V, iyo hadda waa kaliya 1.5A ugu badnaan.
Iyo hadda waxa lagu xaddidi doonaa tayada fiilada dallacaadda, sidaas darteed marxaladda hore ee horumarinta dallacaadda degdegga ah, ujeedada ugu weyn waa in la kordhiyo tamarta.Tani waxay la jaanqaadi kartaa inta badan khadadka gudbinta.Si kastaba ha ahaatee, maadaama aysan xilligaasi jirin nidaam dallacaad mideysan, soosaarayaal kala duwan ayaa soo saaray hab-maamuuska dallacaadda, sidaas darteed Ururka USB wuxuu bilaabay Bixinta Awood si uu u mideeyo borotokoolka dallacaadda.
Bixinta Korontadu waa ka awood badan tahay in aysan taageereynin ku dallacaadaha tamarta yar ee aaladaha, laakiin sidoo kale waxay taageertaa ku dallacaadda aaladaha awoodda sare leh sida buug-yaraha.Markaa aan wax ka baranno borotokoolka PD!
2.Hordhac awood bixinta
Waxaa jiray saddex nooc oo PD ah ilaa hadda, PD / PD2.0 / PD3.0, oo ay ka mid yihiin PD2.0 iyo PD3.0 ayaa ah kuwa ugu badan.PD waxay bixisaa heerar kala duwan oo profiles ah iyadoo loo eegayo isticmaalka tamarta kala duwan, waxayna taageertaa qalabyo kala duwan oo kala duwan,ka telefoonada gacanta, tablet-yada, kombiyuutarada.
PD2.0 waxay bixisaa noocyo kala duwan oo danab ah iyo isku-darka hadda jira si loo buuxiyo shuruudaha tamarta ee qalabka kala duwan.
PD2.0 waxay leedahay shuruud, taas oo ah, borotokoolka PD kaliya wuxuu taageeraa ku dallaca USB-C, sababtoo ah borotokoolka PD wuxuu u baahan yahay biinno gaar ah oo USB-C ah oo loogu talagalay isgaarsiinta, markaa haddii aad rabto inaad isticmaasho PD si aad u dalacdo, ma aha oo kaliya xajiyeyaasha iyo si loo taageero borotokoolka PD, aaladda terminalku waxay u baahan tahay in lagu dalaco USB-C iyada oo la marayo USB-C ilaa USB-C fiilada ku dallaca.
Buugaagta xusuus-qorka, buug-yaraha wax-qabadkiisu aad u sarreeyo wuxuu u baahan karaa koronto 100W ah.Kadib, iyada oo loo marayo borotokoolka PD, buug-yaraha wuxuu codsan karaa astaanta 100W (20V 5A) ee korontada, iyo sahayda korantadu waxay siin doontaa buug-yaraha 20V iyo ugu badnaan 5A.Korontada.
Haddii moobilku u baahan yahay in la dallaco, markaa talefanka gacanta uma baahna koronto badan oo wattage ah, markaa waxa uu quseeyaa 5V 3A profile oo leh koronto, sahayda korontadu waxay siinaysaa taleefanka gacanta 5V, ilaa 3a.
Laakin PD waa heshiis isgaarsiineed.Waxaad ogaan kartaa in aaladda terminalka iyo korontadu ay codsadeen muuqaal gaar ah hadda, laakiin dhab ahaantii, sahayda korantada ayaa laga yaabaa inaysan awoodin inay bixiso wattage sare.Haddii korontadu aysan lahayn wax soo saar koronto oo sidaas u sarreeya, sahayda korontada ayaa ka jawaabi doonta.Muuqaalkan uma heli karo aaladda terminalka, fadlan bixi profile kale.
Markaa dhab ahaantii, PD waa luqadda xidhiidhka u dhexeeya sahayda korantada iyo aaladda terminalka.Iyada oo la adeegsanayo isgaadhsiinta, xalka tamarta ku habboon ayaa la isku duway.Ugu dambeyntii, sahayda korontadu waa soo baxday oo terminalku wuu aqbalayaa.
3.Summary - PD Protocol
Kan sare waa hordhaca "qiyaasta" ee borotokoolka PD.Haddii aadan fahmin, waa caadi, waa caadi.Kaliya waxaad u baahan tahay inaad ogaato in borotokoolka PD uu si tartiib tartiib ah u midayn doono borotokoolka dallacaadda mustaqbalka.Laptop-kaga waxaa si toos ah looga dalaci karaa dalacaadda PD-ga iyo fiilada ku dallaca ee USB Type-C, sidoo kale talefoonka gacanta iyo kamaradaada.Marka la soo koobo, uma baahnid inaad wax dalacdo mustaqbalka.Xajiyeyaasha badan, waxaad u baahan tahay hal xabbo oo PD ah.Si kastaba ha ahaatee, ma aha oo kaliya PD charger.Habka dallacaadda oo dhan waxay ku lug leedahay: charger-ga, fiilada dallacaadda iyo terminalka.Dabeyuhu waa in aanu haysan oo kaliya wattage wax soo saar oo ku filan, laakiin sidoo kale fiilada ku dallacadu waa in ay lahaataa awood ku filan Xawaaraha ugu dhakhsaha badan si aad si buuxda ugu dallaciso qalabkaaga, waxaana laga yaabaa in aad fiiro gaar ah u yeelato marka xigta ee aad soo iibsanayso charging.
