Kwadalwa ngo 08.03
Enkathini ye-Industry 4.0, i-IoT kanye ne-edge computing, izinhlelo ezishumekelayo zesizukulwane esisha ziguquke zisuka emishinini eyisisekelo esebenzayo zaba amathuluzi ahlakaniphile, aguqukayo anamandla okwenza izinqumo ngesikhathi sangempela. Ubuhlakani bokubona buye baba umnyombo walokhu kuguquka—ukuthwebula, ukucubungula nokusebenza ngemininingwane ebonakalayo ngqo kudivayisi. Nakuba ukubona okushumekelwe kwakukade kuncike ezinkundleni eziyinkimbinkimbi, ezibizayo ezifana ne-MIPI CSI-2 noma i-GigE, amamojula ekhamera ye-USB asephenduke isixazululo esisebenzayo, esisebenza kahle kakhulu. Kude nokuba ezinye izindlela ezingabizi, ezanamuhlaAmamojula ekhamera ye-USB ahlinzeka ngobulula, ukusebenza kahle kanye nokukhula ukuze kuhambisane nezidingo zobuhlakani be-edge. Lo mhlahlandlela uhlanganisa izinzuzo eziyinhloko, ukuthuthukiswa kwezobuchwepheshe, izimo zokusetshenziswa kwangempela, amathiphu okukhetha kanye nezitayela zesikhathi esizayo zokuthuthukiswa kwezinhlelo ezishumekiwe.
Izinzuzo Eziyinhloko Zamamojula Ekhamera Ye-USB Ezinhlelweni Ezishumekiwe
Amasistimu asezingeni elandelayo (amarobhothi ezimboni, izinto ezifakwa emzimbeni zezokwelapha, amadivayisi asekhaya ahlakaniphile, izinzwa ze-IoT ezizimele) abelana ngezidingo ezintathu ezibalulekile: usayizi omncane, ukusetshenziswa kwamandla okuphansi kanye nokuhlanganiswa okulula. Izixhumanisi zamakhamera zendabuko zivame ukwehluleka, kodwa amamojula wamakhamera we-USB axazulula lezi zinkinga kuyilapho esekela imisebenzi yokubona ehlakaniphile.
1. Ukuhambisana Okuphezulu Nokuhlanganiswa Kokudlala Nokuxhuma
Amamojula wamakhamera we-USB anamuhla alandela izinga le-USB Video Class (UVC), asebenza ne-Windows, Linux, Android, Raspberry Pi OS, Ubuntu Core kanye namanye amasistimu asezingeni elandelayo ngaphandle kwama-driver enziwe ngokwezifiso. Lokhu kunciphisa isikhathi sokuthuthukisa ngama-20–40% uma kuqhathaniswa namadivayisi angewona awe-UVC, kusheshise isikhathi sokufika emakethe kuma-SME nama-startups.
2. Umkhawulokudonsa Ophezulu Wokusebenza Okuphezulu Kakhulu
Izindinganiso ze-USB ezibuyekeziwe (USB 3.2 Gen 2, USB4) zivala igebe lokusebenza ngezixhumanisi zezinga eliphezulu:
• USB 3.2 Gen 2: Umkhawulokudonsa we-10 Gbps, usekela ividiyo ye-4K/60fps
