Kuti muthe kutsitsa makina owonera makanema omwe akuchulukirachulukira, kusinthaku kumayenera kupeza makamera ochulukirapo, ndikukulitsa kuchuluka kwa data yosinthira. Kusinthana kuyenera kukhala ndi luso lokhazikika losinthira deta kuti ipereke ndalama zambiri komanso mosalekeza Kanema deta. Ndiye, kodi switch ya ethernet isankhe 100M kapena 1000M?

Deta yomwe imaperekedwa pa nthawi ya unit panthawi yotumizira deta imatchedwa code stream, ngati kuchuluka kwa deta yotumizidwa ndi kamera pansi pa chosinthira kupitirira mphamvu yotumizira ya doko linalake, zidzachititsanso kuti dokoli litayitse deta yambiri komanso kuyambitsa mavuto.

Mwachitsanzo, kusintha kwa 100M kumapititsa patsogolo voliyumu ya data yopitilira 100M, zomwe zingayambitse kutayika kwakukulu kwa paketi, zomwe zimapangitsa kuti mawonekedwe aziundana. Ndiye, ndi makamera angati omwe muyenera kusankha chosinthira cha gigabit?

Pali muyezo, kutengera kuchuluka kwa deta yomwe imatumizidwa ndi doko la uplink la kamera: ngati kuchuluka kwa data yomwe yatumizidwa ndi doko la uplink ndi yayikulu kuposa 70M, sankhani doko la gigabit, ndiye kuti, sankhani gigabit switch kapena gigabit uplink switch. .

Pali njira yowerengera mwachangu ndi kusankha: bandwidth value = (sub stream + main stream) * chiwerengero cha mayendedwe * 1.2:

① Bandwidth value> 70M, gwiritsani ntchito gigabit;

②Bandwidth value

Funso 1: Njira yowerengera ma code stream ndiyomveka bwino, koma chifukwa chiyani iyenera kuchulukitsidwa ndi 1.2?

Chifukwa molingana ndi mfundo ya kulumikizana kwa maukonde, encapsulation ya mapaketi a data imatsatiranso protocol ya TCP/IP, ndipo gawo la data liyenera kulembedwa ndi minda yamutu pagawo lililonse la protocol kuti ifalitsidwe bwino, kotero mutu udzakhalanso ndi gawo lina la pamwamba.
The 4M bit rate ndi 2M bit rate ya kamera yomwe timakamba nthawi zambiri imatanthawuza kukula kwa gawo la deta. Malinga ndi chiŵerengero cha kuyankhulana kwa deta, mutu wapamwamba umawerengera pafupifupi 20%, choncho ndondomekoyi iyenera kuchulukitsidwa ndi 1.2.

Funso 2: Chifukwa chiyani 70M si 100M?

Makamaka kuganizira kuchuluka kwa magalimoto. Kanema wa data amapangidwa ndi mafelemu ambiri. Dongosolo lowoneka bwino la data limakhala ndi kuphulika kwapanthawi yomweyo kwa data. Izi zimafuna kusintha kuti musungidwe ndikukonza kusinthasintha kwa data.
Kusinthako kumasunga-patsogolo-sitolo-patsogolo deta izi, kotero tikulimbikitsidwa kukhala ndi kusungitsa kwina. Popanga maukonde osinthira, pakhoza kukhala 30% -40% kusungitsa. Pa doko la 100M, tikulimbikitsidwa kuti magalimoto otumizira zisapitirire 70M.
