Momwe mungamvetsetse mulingo wachitetezo cha IP wa module yokhazikika ya barcode scanning?

Pamene makampani amagulabarcode scanningma modules, ma QR code scanning modules, ndima scanner a QR code osakhazikika,mudzawona nthawi zonse kuchuluka kwa mafakitale a chipangizo chilichonse chojambulira chomwe chatchulidwa pazida zotsatsira，Kodi mulingo wachitetezo uwu ukutanthauza chiyani?Pali mawu akuti, gawo lojambulira barcode lokhazikika lili ndi chipolopolo chosiyana chokhala ndi injini ya QR code, yabwino. kutetezedwa kwa mpweya, moyo wautali wautumiki, ndipo nthawi zambiri amakhala ndi mawonekedwe osalowa madzi, osapumira fumbi komanso otsika, ndipo amatha kukhazikika (ophatikizidwa, ophatikizidwa kunja) ntchito zosiyanasiyana zophatikizira zida zanzeru.
Izi zikuwonetsa, ndi2d matrix barcode scanneramagwiritsidwa ntchito m'mawonekedwe amkati ndi akunja, zomwe zimafunikira pachitetezo cha IP cha zida zojambulira ndizosiyana kotheratu. Kenako, titha kumvetsetsanso lingaliro la IP chitetezo level. IP chitetezo ndi muyezo wofunikira pakutetezedwa kwa zida zamagetsi. , IP chitetezo rating system imapereka njira yogawa zinthu potengera kukana fumbi, kusalowa madzi ndi kugunda kwa zida zamagetsi ndi ma CD.
Mlingo wachitetezo nthawi zambiri umawonetsedwa ndi IP ndikutsatiridwa ndi manambala a 2, ndipo manambala amagwiritsidwa ntchito kumveketsa kuchuluka kwa chitetezo.Nambala yoyamba ikuwonetsa kuchuluka kwa zida zolimbana ndi fumbi, kapena kuchuluka komwe anthu amatetezedwa ku zoopsa m'malo osindikizidwa. .Ndikuyimira mlingo woletsa zinthu zolimba zakunja kuti zilowemo, ndipo mlingo wapamwamba kwambiri ndi 6; Nambala yachiwiri imasonyeza mlingo wa kukana kwa madzi kwa zipangizo, zomwe zimayimira mlingo wa chitetezo ku ingress ya madzi.Mlingo wapamwamba kwambiri ndi 8.
