Mawu OyambazaCTIA

Cellular Telecommunications Industry Association (CTIA) ili ndi dongosolo la certification lophimba ma cell, mabatire, ma adapter ndi makamu ndi zinthu zina zomwe zimagwiritsidwa ntchito pazinthu zoyankhulirana zopanda zingwe (monga mafoni am'manja, ma laputopu). Pakati pawo, certification ya CTIA yama cell ndiyovuta kwambiri. Kupatula kuyesedwa kwachitetezo chambiri, CTIA imayang'ananso mapangidwe a maselo, njira zazikulu zopangira komanso kuwongolera kwake. Ngakhale satifiketi ya CTIA sikofunikira, oyendetsa ma telecom ku North America amafuna kuti zinthu zomwe ogulitsa awo azipereka ziphatikizidwe ndi certification ya CTIA, chifukwa chake satifiketi ya CTIA imatha kuonedwanso ngati chofunikira cholowera msika waku North America.

Mbiri Yamsonkhano

Muyezo wa certification wa CTIA wakhala ukunena za IEEE 1725 ndi IEEE 1625 yofalitsidwa ndi IEEE (Institute of Electrical and Electronics Engineers). M'mbuyomu, IEEE 1725 idagwiritsidwa ntchito ku mabatire opanda dongosolo; pomwe IEEE 1625 imagwiritsidwa ntchito pamabatire okhala ndi zolumikizira ziwiri kapena zingapo. Monga pulogalamu ya satifiketi ya batri ya CTIA yakhala ikugwiritsa ntchito IEEE 1725 ngati muyeso, pambuyo pa kutulutsidwa kwa mtundu watsopano wa IEEE 1725-2021 mu 2021, CTIA yapanganso gulu lothandizira kuyambitsa pulogalamu yokonzanso certification ya CTIA.

Gulu logwira ntchito linapempha kwambiri maganizo kuchokera ku ma laboratories, opanga mabatire, opanga mafoni a m'manja, opanga makina, opanga ma adapter, ndi zina zotero. Mu May chaka chino, msonkhano woyamba wa CRD (Certification Requirements Document) unachitika. Panthawiyi, gulu lapadera la adaputala linakhazikitsidwa kuti likambirane za mawonekedwe a USB ndi nkhani zina mosiyana. Patadutsa theka la chaka, semina yomaliza idachitika mwezi uno. Zimatsimikizira kuti dongosolo latsopano la certification la CTIA IEEE 1725 (CRD) lidzaperekedwa mu December, ndi kusintha kwa miyezi isanu ndi umodzi. Izi zikutanthauza kuti certification ya CTIA iyenera kuchitidwa pogwiritsa ntchito mtundu watsopano wa chikalata cha CRD pambuyo pa Juni 2023. Ife, MCM, monga membala wa CTIA's Test Laboratory (CATL), ndi CTIA's Battery Working Group, tinakonza zokonzanso dongosolo latsopanoli ndipo tinatenga nawo mbali. pazokambirana za CTIA IEEE1725-2021 CRD. Zotsatirazi ndi zofunika kukonzanso:

Kuunikanso Kwakukulu

1. Zofunikira pa batire / paketi subsystem zidawonjezedwa, zogulitsa ziyenera kukumana ndi UL 2054 kapena UL 62133-2 kapena IEC 62133-2 (yopatuka ku US). Ndikoyenera kudziwa kuti m'mbuyomu palibe chifukwa choperekera zikalata zilizonse za paketi.
2. Pakuyesa kwa ma cell, IEEE 1725-2021 idachotsa mayeso afupipafupi a cell pambuyo pa 25 kutentha kwakukulu komanso kutsika. Ngakhale CTIA yakhala ikunena za muyezo wa IEEE, pamapeto pake idaganiza zosunga mayesowa. Uku ndikulingalira kuti mikhalidwe yoyezetsa ndiyowopsa, koma kwa ukalamba wina, mabatire oyipa, mayeso otere amatha kuzindikira momwe zinthu zikuyendera nthawi yomweyo. Ikuwonetsanso kutsimikiza kwa CTIA kuwongolera mosamalitsa chitetezo cha maselo.
3. CRD yatsopano ya CTIA IEEE 1725 imachotsa zinthu zoyeserera za USB Type B ndikusinthanso malire oyeserera a zida zolandirira alendo kuchokera pa 9V kupita ku 24V kuti zigwirizane ndi mawonekedwe a USB Type C. Izi zikuwonetsanso kuti nthawi yosinthira ikatha chaka chamawa, ma adapter a USB Type B sangathenso kufunsira chiphaso cha CTIA. Izi zimagwiranso ntchito kumakampani, omwe tsopano akusintha ma adapter a USB Type B kukhala ma adapter a USB Type C.
4. Kuchulukitsa kwazinthu za 1725 kukukulitsidwa. Ndi kuchuluka kwa batire ya foni yam'manja, mphamvu ya batire ya cell imodzi sikungathenso kukumana ndi kugwiritsa ntchito foni yam'manja nthawi yayitali. Chifukwa chake, chiphaso cha IEEE 1725 chotsimikizira batire la foni yam'manja chimakulitsanso masanjidwe amtundu wa batri.

• Selo imodzi (1S1P)
• Maselo angapo ofanana (1S nP)
• Ma cell a 2 osiyanasiyana (2S nP)

Zonse zomwe zili pamwambazi zitha kutsimikiziridwa pansi pa CTIA IEEE 1725, ndipo masanjidwe ena a batri ayenera kukwaniritsa zofunikira za CTIA IEEE 1625.

Chidule

Poyerekeza ndi Baibulo lakale, latsopano sasintha kwambiri mu zinthu mayeso, koma Baibulo latsopano amaika patsogolo angapo zofunika chiphaso latsopano, kufotokoza kukula kwa chiphaso mankhwala, etc. Ndipo adaputala chaputala anali zayamba kusinthidwa. Cholinga cha certification ya adaputala ndikutsimikizira mitundu ya mawonekedwe omwe amagwiritsidwa ntchito kwambiri, ndipo USB Type C imagwirizana kwambiri ndi mapulogalamu ambiri. Kutengera izi, CTIA imagwiritsa ntchito USB Type C ngati mtundu wokhawo wa adaputala. Pakali pano EU ndi South Korea ali ndi ndondomeko yogwirizanitsa mawonekedwe a USB, chisankho chomwe CTIA inapanga chosiya USB Type B ndi kupita ku USB Type C chimayalanso maziko a mawonekedwe ogwirizana a USB ku North America mtsogolomo.

Kuonjezera apo, ndemanga zomwe zili pamwambazi ndi zosinthidwa ndizo zomwe zinavomerezedwa pamsonkhanowo, malamulo omaliza ayenera kutanthauza ndondomeko yovomerezeka. Pakadali pano mtundu watsopano wa muyezowu sunatulutsidwebe ndipo ukuyembekezeka kuperekedwa mkati mwa Disembala.
