Mliri wa coronavirus wa 2019-20 ndi vuto lomwe likuchitika padziko lonse lapansi lomwe likukhudza matenda a coronavirus.Mwina mwawonapo momwe matendawa amabweretsera zovuta pamoyo watsiku ndi tsiku.CDC idati pafupifupi 80% ya majeremusi omwe amayambitsa matenda amafalikira kudzera m'manja.Chifukwa chake, njira yolowera popanda kukhudza imalepheretsa manja kuti asatengeke ndi ma virus ndi mabakiteriya.Ndipo zotetezedwa zomwe zimazindikirika ndi kutentha thupi zimafunidwa kwambiri pamsika.Apa Granding imapereka kuyenda kudzera pa chowunikira chachitsulo chokhala ndi sensa ya kutentha kwa IR, kuzindikira kowoneka kumaso ndikuzindikira kutentha thupi, komanso kuwongolera polowera polowera ndi kuzindikira kwamaso mwachangu.
Nayi chidule chachidule cha zinthu za Granding touchless biometric:
Yendani Kupyolera mu Metal Detector Ndi IR Temperature Sensor (D8130S-TD)
Khomo lachitetezo lakutali lakutali lachitetezo cha kutentha kwa thupi la munthu ndikuzindikira chitetezo chophatikizidwa ndi kuzindikira kutentha kwa thupi la munthu komanso kuzindikira kwachitsulo.
Mutu wa chitseko uli ndi chofufumitsa chodziwikiratu, ngodya yodziwikiratu imatha kusunthira mmwamba ndi pansi, ndipo kutentha kwapamphumi kwamunthu kumatha kuyeza.
Chigawo cha kuwala cha detector chimasonkhanitsa mphamvu zomwe zimatulutsidwa ndikuwonetseredwa ndi mphumi pa sensa, ndikuwonetsa chidziwitso chachiwiri pa gulu lowonetsera kupyolera mu gawo lamagetsi.
Kuwerenga kwa kutentha kukadutsa mtengo wa alamu wotentha kwambiri, chidacho chimatumiza phokoso la alamu.Kutentha kwa alamu kumatha kukhazikitsidwa ngati mtengo uliwonse pakufuna kwanu.
Khomo lachitetezo ili ndi loyenera kuyang'anira chitetezo cha zinthu zoopsa monga mipeni yoyendetsedwa ndi zinthu zokakamizidwa.Amagwiritsidwa ntchito kwambiri m'mabwalo a ndege, masiteshoni, alendo, masukulu, maofesi, mafakitale, madera ndi malo ena okhala ndi anthu ambiri.Chipata chachitetezochi ndi chothandiza poletsa kufalikira kwa mliri.
Panthawi ya mliri wapadera, anthu azivala chigoba kuti adziteteze.Ndipo popanga kuzindikira nkhope, kuthamanga komanso kuzindikirika kuti mukumane ndi chigoba kumafunika pamsika.Kuzindikira Kwankhope Kwapamwamba Kwambiri Dynamic Visible Light Recognition yokhala ndi chigoba ndi chowunikira kutentha, sichimakhudzanso kutsimikizika kwa Ukhondo wa biometric, kuzindikira kutentha ndi kuzindikiritsa munthu wobisika.Anti-spoofing algorithm motsutsana ndi print attach (laser, color and B/W photos), mavidiyo akuwukira ndi 3D mask attack.
Ndiwopanda kukhudza komanso osalumikizana, ingoyimirirani kutali kuti muzindikire, kudziwa kutentha kwa thupi ndi mtunda wa 30 ~ 50CM (1 ~ 1.64feet), Kuyeza kwa 34 ~ 45 ℃ ndi Kulondola ± 0.3.
Nkhope Yophimbidwa
Munthawi ya mliri, kuvala chigoba cha opaleshoni ndikofunikira musanalowe m'malo odzaza anthu monga maofesi, malo ogulitsira, masiteshoni ndi zina zotero.Anthu osavala chophimba amatha kuwoneka ngati akufalitsa majeremusi mdera lanu popeza madontho ndi njira imodzi yowopsa komanso yosavuta yofalira coronavirus.Mothandizidwa ndi ukadaulo wa Computer Vision, ma terminals okweza a Granding amatha kuzindikira ngati wogwiritsa ntchito wavala chigoba, pomwe akuwonetsa kuzindikira kumaso mwachangu komanso kothandiza.
Kuzindikira malungo
Makamera ambiri otentha pamsika amapangidwa kuti azigwiritsidwa ntchito m'mafakitale okha.Kuzindikira kutentha kotereku kumatha kuloledwa mpaka madigiri ±2 apatuka, zomwe sizolondola kwenikweni pakuwunika kutentha kwa thupi la munthu panthawi ya mliri wa matenda.Kuti athetse vutoli, Granding imaphatikiza ukadaulo wozindikira nkhope wowoneka bwino ndi mawonekedwe a kutentha kwa infrared kuti apereke kuwunika kolondola komanso kofulumira kwa kutentha panthawi yotsimikizira kutentha.
