Maitiro ekugadzira fekitori kugadzirisa iyo USB C hub simba rekupa system dambudziko


Nguva yekutumira: Oct-29-2021

MuGuangdong Dongguan, kune akati wandei mafekitori emaindasitiri akati wandei, ndosaka guta rakadaidza fekitori yenyika.Pakati pemafekitori aya, iyo USB hub fekitori ndeimwe yeayo otomatiki chigadzirwa, zvinoreva kuti vanoshandisa tekinoroji nyowani kugadzirisa nyaya dzekugadzira.

Iyo USB network inovakwa kubva ku USB hubs yakabatana kuzasi kune USB ports, iyo pachayo inogona kubva ku USB hubs.USB hubs inogona kuwedzera USB network kusvika pakakwirira 127 ports.Iyo USB dhizaini inoda kuti mabhazi-powered (passive) hubs haana kubatana munhevedzano kune mamwe mabhazi-ane simba hubs.

Zvichienderana nemutengesi uye dhizaini, USB ports inowanzo paradzana.Nekuda kweizvozvo, kubaya mudziyo muchiteshi chimwe chete kunogona kuvhara chiteshi chiri padyo, kunyanya kana plug isiri chikamu chetambo asi yakakosha kune mudziyo wakaita se USB flash drive.Rondedzero yakachinjika yemasoketi angave nyore kugadzira, asi anogona kukonzera maviri chete kubva mana madoko kuti ashandiswe (zvichienderana nehupamhi hweplug).

Port arrays umo chiteshi chengarava chiri perpendicular kune array orientation kazhinji ane mashoma ekuvharika matambudziko.Ekunze “Octopus” kana “Squid” hubs (ine soketi imwe neimwe kumagumo kwetambo pfupi kwazvo, kazhinji inosvika masendimita mashanu) kureba), kana “nyeredzi” hubs (ine chiteshi chega chega chakatarira kune rimwe divi, semufananidzo. ) dzivisa dambudziko iri zvachose.

Kuganhurirwa kweurefu
Tambo dze USB dzinogumira kumamita matatu (mafiti gumi) kune yakaderera-speed USB 1.1 zvishandiso.Hub inogona kushandiswa seinoshingaira USB inodzokorora kureba kwetambo kusvika kumamita mashanu (16 tsoka) kureba panguva.Tambo dzinoshanda (specialized connector-embedded one-port hubs) dzinoita basa rimwe chete, asi sezvo dziine bhazi-powered, ekunze powered USB hubs zvingangodiwa kune zvimwe zvikamu.

Simba
Hub-powered hub (passive hub) ihabhu inokweva simba rayo rese kubva kune iyo komputa inotakura USB interface.Izvo hazvidi rakaparadzana simba rekubatanidza.Nekudaro, zvishandiso zvakawanda zvinoda simba rakawanda kupfuura nzira iyi inogona kupa uye haishande mumhando iyi yehubhu.Zvingave zvinodiwa kushandisa bhasi-powered hub ine self-powered ekunze hard-disks, sezvo iyo hard-disk inogona kusatenderera pasi kana komputa ichidzima kana kupinda mumodhi yekurara ichishandisa hubhu inozvimiririra kubva kune hard disk controller. yaizoenderera mberi nekuona sosi yemagetsi pane USB ports.

A USB's electric current yakagoverwa muzvikamu zve 100 mA kusvika kune inokwana 500 mA pachiteshi.Naizvozvo, bhazi rinoenderana nemagetsi hub rinogona kunge risingapfuure mana kuzasi zviteshi uye harigone kupa anopfuura mana 100 mA mayunitsi ezvino zvakazara kumidziyo yepasi (sezvo hub inoda imwe unit yega).Kana mudziyo uchida mamwe mayunitsi emazuvano kupfuura chiteshi chayakabairwa ichikwanisa kupa, sisitimu yekushandisa inowanzo zivisa izvi kumushandisi.

Kusiyana neizvi, hub inozvimiririra (inoshanda hub) inotora simba rayo kubva kune yekunze magetsi ekupa uye saka inogona kupa simba rakazara (kusvika ku500 mA) kuchiteshi chese.Mazhinji hubs anogona kushanda semabhazi anofambiswa nemagetsi kana ega ega.

Nekudaro, kune akawanda asingaenderane hubs pamusika anozvizivisa kune muridzi seanozvifambisa kunyangwe aine bhazi-powered.Zvakangofanana, kune zvakawanda zvisingaenderane zvishandiso zvinoshandisa zvinopfuura 100 mA pasina kuzivisa chokwadi ichi.Aya mahubhu nemidziyo inobvumira kuchinjika mukushandiswa kwesimba (kunyanya, michina mizhinji inoshandisa isingasviki zana mA uye akawanda ma USB ports anogona kupa zvinopfuura mazana mashanu mA asati apinda mukuvharika kwekuremerwa), asi ivo vanogona kugadzira. matambudziko emagetsi zvakaoma kuongorora.

Mamwe mahubhu anozviita ega haapi simba rakakwana rekutyaira 500 mA mutoro pachiteshi chese.Semuyenzaniso, akawanda manomwe ma port hubs ane 1 A magetsi, asi chokwadi zviteshi zvinomwe zvaigona kudhiza inodarika 7 x 0.5 = 3.5 A, pamwe nesimba rehub pachayo.Vagadziri vanofungidzira kuti mushandisi angangobatanidza akawanda akaderera magetsi zvishandiso uye imwe chete kana maviri inoda yakazara 500 mA.Kune rimwe divi, kurongedzerwa kwemamwe ma-powered hubs anotaura zvakajeka kuti mangani emachiteshi anogona kutyaira 500 mA yakazara mutoro kamwechete.Semuyenzaniso, kurongedzerwa pane 7-port hub inogona kuti inotsigira inokwana mana-yakazara-yakazara midziyo.

Dynamic-powered hubs inzvimbo dzinokwanisa kushanda semabhazi-powered pamwe neanozvifambisa ega.Ivo vanogona kushandura otomatiki pakati pemodhi zvichienderana nekuti yakasarudzika magetsi inowanikwa here kana kwete.Nepo kuchinja kubva pakushandisa bhazi kuenda kune rinozvishandisa pacharo hazvidi kuti pave nekukurumidzira kutaurirana neanotambira, kuchinja kubva kune wega-wega kuenda kune inofambiswa nebhazi kunogona kuita kuti ma USB agadziriswe kana michina yakabatana yakambokumbira simba rakawanda kupfuura rinowanikwa mubhazi- powered mode.
