Malinga ndi Bluetooth Sig, Bluetooth mtundu 5.4 watulutsidwa, kubweretsa muyezo watsopano wa ma tag a ma tag. Zikumveka kuti kusintha kwaukadaulo wokhudzana, mbali imodzi, chikwama chamtengo chomwe chimatha kukulitsidwa mpaka 32640, pomwepo, njira ya chipata itha kuzindikira kulumikizana kwamitengo iwiri.
Nkhanizi zimapangitsanso anthu kudziwa mafunso angapo: Kodi ndi luso laukadaulo watsopano ndi liti? Kodi zimapangitsa kuti pagwiritsidwa ntchito ndi ma tag amtengo wamagetsi? Kodi isintha chitsanzo cha mafakitale? Kenako, pepala ili likambirana nkhani zomwe zili pamwambapa, zomwe zikuchitika mtsogolo kwa ma tag a ma tag.
Apanso, zindikirani kuwunika kwamagetsi
Katundu wamagetsi, LCD ndi pakompyuta zowonetsera zamagetsi ndi ntchito yotumiza ndi kulandira chidziwitso, kulumikizana kopanda zingwe kuti mukwaniritse kusintha kwa chidziwitso cha mitengo. Chifukwa imatha kusintha mitengo yamiyambo yachikhalidwe, yophatikizika ndi kugwiritsa ntchito mphamvu yamagetsi (inki screencle electronchic mitengo yolumikizirana ndi mabatire okwanira zaka zopitilira 5 za kupirira), zimakomedwa ndi ambiri ogulitsa ogulitsa. Pakadali pano, imagwiritsidwa ntchito kwambiri mu bizinesi yapamwamba komanso yachilendo ku Wal-Mart, Yongghui, Hema watsopano, nyumba ndi zina zotero.
Ndipo Tag yamagetsi sikuti ndi chizindikiro chabe, koma kachitidwe lonse kumbuyo kwake. Nthawi zambiri, makina amagetsi amaphatikizanso magawo anayi: ESL yamagetsi (esl), ma raise), pakompyuta pakompyuta
Mfundo yoyendetsera dongosolo ndi iyi: Gwirizanitsani zidziwitso zamitengo papulatifomu ya Saas, ndikutumiza zidziwitso ku tag yamagetsi kudzera pa station ya ESL. Mukalandira chidziwitsocho, ndalama zamtengo zimatha kuwonetsa bwino zinthu zoyambira monga dzina, mtengo, komwe adachokera nthawi yeniyeni. Momwemonso, zambiri za malonda zitha kusinthidwanso zamilandu poyang'ana nambala yazogulitsa kudzera pa PDA.
Pakati pawo, kufalitsa zidziwitso kumadalira ukadaulo wopanda zingwe. Pakadali pano pali ma protococococor a Expremping to omwe amagwiritsidwa ntchito pamtengo wamagetsi: 433 Mhz, patokha 2.4gz, Bluetooth, ndipo aliyense mwa ma protocols ali ndi zabwino zake komanso zovuta zake.
Chifukwa chake, Bluetooth ndi amodzi mwa ma protocol, koma pamsika, pamsika, Bluetooth ndi Speritol Protefol imafanananso chimodzimodzi. Koma tsopano Bluetoooth kwa mtengo wamagetsi kuti akhazikitse muyezo watsopano, sizovuta kuwona, ndikugwira mtengo wamagetsi pamsika womwe ukufunsira.
Kodi chatsopano ndi cha Bluetoth Serviedy?
Pakadali pano, ma radius oyambira a esl maziko a esl ali pakati pa 30-40 metres, ndipo chiwerengero chokwanira cha ma tag omwe amatha kukhalapo mosiyanasiyana kuchokera ku 1000-5000. Koma molingana ndi mtundu wa Bluetooth Core mtundu wa ukadaulo watsopano 5.4, mothandizidwa ndi ukadaulo watsopano, netiweki imatha kulumikizana ndi zida 32,640, kuwonjezera pa kukwaniritsidwa kwa zida za ESL ndi chipata cha njira ziwiri.
Bluetooth 5.4 Kusintha mawonekedwe awiri okhudzana ndi mitengo yamagetsi:
1. Kutsatsa kwa nthawi yayitali ndi mayankho (pawr, kutsatsa kwakanthawi ndi mayankho)
Pawr ilola kukhazikitsa networ network yokhala ndi kulumikizana kwa njira ziwiri, gawo lomwe limawonjezera mphamvu ya zida esl kulandira deta ndikuyankha kwa wotumiza. Kuphatikiza apo, zida esl zitha kugawidwa m'magulu angapo, ndipo chipangizo chilichonse cha esl chili ndi adilesi yowonjezera ndikuwonjezera kulumikizana ndi chimodzi komanso zingapo.
Pacithunzi-thunzi apa, AP ndi wotchuka kwambiri; ESL ndi mtengo wamagetsi (wa grpps yosiyanasiyana, ndi ma IDS); kugonjera ndi njira yopasuka; RSP SLOT ndiye kaya yankho. Mu chithunzi, mzere wakuda ndi kutumiza ma ap ndi mapaketi a esl, ndi mzere wofiira ndi esl poyankha ndi kudyetsa AP.
Malinga ndi bluetooth core mtundu wofanizira (ESL imagwiritsa ntchito chida cholembera (binary) chokhala ndi ma 8-bit a esl ndi ma ed 7-bit. Ndipo ID ya ESL ili yapadera m'magulu osiyanasiyana. Chifukwa chake, kuvala kwa zitsimikiziro za esl kumatha kukhala magulu 128, iliyonse yomwe imatha kukhala ndi zida zapadera 255 za mamembala a gululi. Mwanjira yosavuta, pakhoza kukhala zida zokwana 32,640 esl mu netiweki, ndipo zilembo zilizonse zitha kuwongoleredwa kuchokera ku malo amodzi.
2. Kutsatsa malonda otsatsa (ead, sturry)
EAD makamaka imafotokoza za ntchito za deta. Pambuyo poikiridwa deta yomwe imasungidwa, imatha kulandiridwa ndi chipangizo chilichonse, koma chitha kungochepetsedwa ndikutsimikiziridwa ndi chipangizo chomwe chinagawana nawo kiyi yolumikizirana. Phindu lalikulu la izi ndikuti zomwe zili pacys zimasintha monga momwe adilesi imasinthira, kuchepetsa mwayi wotsatira.
Kutengera ndi zinthu ziwiri pamwambapa zosintha, Bluetooth idzakhala yopindulitsa kwambiri pakugwiritsira ntchito magetsi. Makamaka poyerekeza ndi 433mhz ndi payekha 2.4ghz, alibe mfundo zolankhulirana padziko lonse lapansi, zokhazikika, chitetezo sichingakhale chotsimikizika bwino, makamaka poyerekeza ndi otetezeka.
Pofika muyezo watsopano, makampani amagetsi a Magetsi amathanso kupanga zosintha, makamaka opanga njira zomwe zimathandizira mafinya a mafakitale a mafakitale. Kwa opanga mabungwe a Bluetooth, ngakhale kuti athandizire zosintha za Ota zogulitsa zinthu komanso kuwonjezera Bluetooth 5.4 kulowa mu mzere watsopano wazogulitsa ndi funso lomwe lingaganizidwe. Ndipo kwa opanga osakhala a Bluetooth, osasintha Conmec.
Komanonso, msika wamagetsi umayenda bwanji masiku ano, ndipo zovuta ndi ziti?
Mtengo wamagetsi wa zamagetsi zamagetsi
Pakadali pano, kudzera pamapepala ogulitsa mapepala ofananira amatha kudziwika, kutumiza kwa mitengo yamagetsi kwatha chaka ndi chaka.
Malinga ndi kuwunika kwa otuwa yapadziko lonse lapansi, ma module a m'ma 190 miliyoni amatumizidwa padziko lonse lapansi mu 2022, up 20,5% kuyambira nthawi yomweyi chaka chatha. Potengera zolemba zamagetsi zamagetsi, kutumiza padziko lonse lapansi kwa zilembo zamagetsi mu magawo atatu oyamba adafika zidutswa 180 miliyoni, ndikukula kwa chaka chimodzi cha 28.6%.
Koma ma tags tsopano akuthamanga mu botolo popeza phindu lowonjezera. Popeza zilembo za zamagetsi zimadziwika ndi moyo wautumiki wautumiki wautumiki, zimatenga zaka zosachepera 5-10 kuti zisinthe m'malo mwake, kotero sipadzakhalanso malo osungirako masheya nthawi yayitali, kotero titha kuyang'ana pamsika wokulira. Vuto, komabe, ndi kuti ogulitsa ambiri safuna kusinthana ndi mitengo yamagetsi. "Ogulitsa ena akhala akuzengereza kuti atenge ukadaulo wa ESL chifukwa cha nkhawa za vendor Lock-in, kugonana ndi kuthekera kokulitsa kafukufuku wa abi.
Mofananamo, mtengo wake ndi vuto lalikulu. Ngakhale mtengo wa tag yamagetsi yasinthidwa kuti muchepetse ndalama zambiri, zimagwiritsidwanso ntchito m'masitolo akuluakulu monga Walmart ndi Yonthhui pamsika wogulitsa. Kwa masitolo akuluakulu amderali, masitolo osasinthika ndi malo ogulitsira mabuku, mtengo wake udakali wokulirapo. Ndipo ndikoyenera kutchulapo kuti mitengo yamagetsi yamagetsi ndiyofunikira chabe masitolo osakhala akulu.
Kuphatikiza apo, makalata apano a ma tagi yamagetsi ndi yosavuta. Pakadali pano, 90% ya ma tag amagetsi amagwiritsidwa ntchito mu gawo la malonda, koma ochepera 10% amagwiritsidwa ntchito muofesi, zamankhwala ndi zochitika zina. Ma ses-fagical mu malonda a digito, amakhulupirira kuti mtengo wa digito suyenera kukhala chida chowonetsa cha omniatic chomwe chingapangitse zopanga za omnihatic zomwe zitha kuthandiza ogula ndikusunga olemba ntchito ndi ndalama.
Komabe, palinso uthenga wabwino kuposa zovuta. Kukhazikika kwa ma tag omwe amapezeka pamsika wapanyumba kumakhala kochepera 10%, zomwe zikutanthauza kuti pali msika wambiri wokhoza kujambulidwa. Nthawi yomweyo, ndikutha kwa njira yowongolera matendawa, kuchira kwa kumwa kumachitika kwakukulu, ndipo kubwezeretsanso kobwerera kumbali yogulitsa kukubweranso, komwenso ndi mwayi wabwino wopangira mitengo yamagetsi kuti apeze msika wamagetsi. Kuphatikiza apo, osewera ambiri opanga mafakitale amataya mitengo yamagetsi yamagetsi, zivomerezi ndi ses-faticag ikugwirizana ndi mitengo yamagetsi yokhazikika. M'tsogolomu, kugwiritsa ntchito ukadaulo wapamwamba komanso kukhazikika kwa miyezo, ma tags apakompyuta amakhalanso ndi tsogolo latsopano.
