Nk'uko byatangajwe na Bluetooth Sig, verisiyo ya Bluetooth 5.4 yasohotse, azana urwego rushya rwo gutanga ibikoresho bya elegitoroniki. Byumvikane ko ivugurura ryikoranabuhanga rijyanye, kuruhande rumwe, igiciro cyigiciro kumurongo umwe gishobora kwagurwa kugera kuri 32640, kurundi rembo hashobora kubona itumanaho ryinzira ebyiri nibiciro.
Amakuru kandi atuma abantu bafite amatsiko kubibazo bike: Ni ubuhe buryo bwa tekiniki muri Bluetooth nshya? Ni izihe ngaruka kubijyanye no gukurikiza ibiciro bya elegitoroniki? Bizahindura imiterere yinganda zisanzwe? Ibikurikira, iyi nyandiko izaganira ku bibazo byavuzwe haruguru, iterambere ry'ejo hazaza h'ibiciro bya elegitoroniki.
Na none, menya igiciro cya elegitoroniki
Ibiciro bya elegitoronike, impapuro za elegitoroniki na elegitoronike zerekana igikoresho cyo kohereza no kwakira amakuru, binyuze mu itumanaho, binyuze mu itumanaho ryatsindiye kugirango ugere kumyandikire y'ibiciro bihinduka. Kuberako irashobora gusimbuza igiciro gakondo cyibiciro, hamwe namashanyarazi make (ink ecran ya elegitoronike ya elegitoroniki hamwe na bateri 2 zirashobora kugera kumyaka irenga 5 yo kwihangana), itoneshwa nabenshi mubakora ibicuruzwa. Kugeza ubu, byakoreshwaga cyane mu gihugu no mu mahanga bizwi cyane ku bucuruzi bwa Super List nka Wal-Mart, Yonghui, Hema Fresh, na ON.
Kandi igiciro cya elegitoronike ntabwo ari ikimenyetso gusa, ahubwo ni gahunda yose inyuma yayo. Muri rusange, ibikoresho bya elegitoronike birimo ibice bine: Igiciro cya elegitoronike (ESL), sitasiyo shingiro ya eslap (eslap), igiciro cya elegitoronike (pda).
Ihame rishinzwe sisitemu ni: Guhuza ibicuruzwa n'ibiciro amakuru y'ibiciro ku gicu cya Saas, hanyuma wohereze amakuru mu giciro cya elegitoroniki binyuze kuri sitasiyo ya ESL. Nyuma yo kwakira amakuru, igiciro gishobora kwerekana amakuru yibanze nkizina, igiciro, inkomoko nibisobanuro mugihe nyacyo. Mu buryo nk'ubwo, amakuru y'ibicuruzwa arashobora kandi guhinduka kumurongo usikana kode yibicuruzwa binyuze muri pompal pda.
Muri bo, kohereza amakuru biterwa n'ikoranabuhanga ry'itumanaho ridafite ishingiro. Kugeza ubu, hari protocole eshatu zamaboko zikoreshwa ku giciro cya elegitoronike: 433 MHZ, PROTOKOTH, BLUETOOH, na buri protokole eshatu zifite ibyiza.
Rero, Bluetooth ni imwe muri protocole isanzwe, ariko mubyukuri, ku isoko, Bluetooth na Protocole ya 2.4GHz ikoresha kimwe. Ariko ubu bluetooth yagenewe igiciro cya elegitoronike kugirango ashyireho ibipimo bishya, ntabwo bigoye kubona, ni ugufata igiciro cya elegitoroniki iyi soko isaba.
Ni iki gishya hamwe na esl esl esl?
Kugeza ubu, ubwishingizi bwa radiyo ya ESL base buri hagati ya metero 30-40, numubare ntarengwa wa tagi ushobora kwakirwa biratandukanye kuva 1000-5000. Ariko ukurikije ibisobanuro bigezweho Bluetooth Compless ya Bluetooth aheruka 5.4, hashingiwe ku nkunga y'ikoranabuhanga Nshya ,,640, usibye gushyira mu bikorwa ibikoresho bya ESL no gushyikirana inzira ebyiri.
Bluetooth 5.4 Kuvugurura ibintu bibiri bijyanye nibiciro bya elegitoronike:
1. Amatangazo yamamaza hamwe nibisubizo (pawr, kwamamaza buri gihe hamwe nibisubizo)
Pawr izemera ko ishyirwa mu bikorwa ry'umuyoboro w'inyenyeri ufite itumanaho ryinzira ebyiri, ikintu cyongera ubushobozi bwibikoresho bya ESL kugirango wakire amakuru kandi usubize uwagutumye. Byongeye kandi, ibikoresho bya ESL birashobora kugabanywa mumatsinda menshi, kandi buri gikoresho cya esl gifite adresse yihariye yo guhuza no gukora imwe-imwe na-imwe-nyinshi.
Ku ishusho, ap ni umunyamakuru wa Pawr; ESL ni igiciro cya elegitoronike (cya grps zitandukanye, hamwe nimpyisi itandukanye); Subeven ni ukwirega; rsp slot nigice. Mu gishushanyo, umurongo utambitse utambitse ni up kohereza amategeko n'amapaki kuri esl, umurongo utambitse utukura ni esl usubiza kandi ugaburira kuri ap.
Nk'uko byatangajwe na verisiyo ya Bluetooth Compandition 5.4, ESL ikoresha igikoresho cyo gukemura ibikoresho (binary) bigizwe na 8-bit esl idl na 7-bit. Kandi indangamuntu ya ESL irihariye mumatsinda atandukanye. Kubwibyo, umuyoboro wibikoresho bya ESL birashobora kubamo amatsinda agera ku 128, buri kimwe muribyo gishobora kubamo ibikoresho bigera kuri 255 byihariye bya ESL byabagize itsinda. Mu magambo yoroshye, hashobora kubaho ibikoresho byose 32.640 esl murusobe, kandi buri kirango kirashobora kugenzurwa muburyo bumwe bwo kugera.
2.. Amatangazo Yamamaza Amakuru (EAD, EDRYPETED TVATCAST)
EAD ahanini itanga amakuru yatangajwe. Nyuma yamakuru yatangajwe ni ibikoresho, ariko birashobora guhorwa gusa no kugenzurwa nigikoresho cyasangiye urufunguzo rwitumanaho. Inyungu zikomeye ziki kintu nuko ibikubiye mu mapaki yatangajwe bihinduka nkigikoresho cya aderesi ihinduka, kugabanya amahirwe yo gukurikirana.
Hashingiwe ku bintu bibiri byavuzwe haruguru byo kuvugurura, Bluetooth bizaba byiza muri porogaramu ya elegitoroniki. Cyane ugereranije na 433mhz na Privates 2.4ghz, nta ngeso mpuzamahanga ikoreshwa, umutekano, umutekano ntushobora kwishingirwaho, cyane cyane mubijyanye no gusobanura bizaba byinshi.
Hamwe no kuhagera kw'ibipimo bishya, ibiciro bya elegitoronike bivuga kandi usunika mu mpinduka zimwe, cyane cyane abakora itumanaho hamwe n'abatanga igisubizo hagati y'uruhererekane rw'inganda. Kubakora ibisubizo bya Bluetooth, niba ugomba gushyigikira ibishya bya OTA kubicuruzwa byagurishijwe kandi niba wongeyeho Bluetooth 5.4 mumirongo mishya yibicuruzwa nikibazo cyo gusuzumwa. Kandi kubishushanyo mbonera bya bluetooth, niba ugomba guhindura gahunda yibanze kugirango ukoreshe Bluetooth nacyo nikibazo.
Ariko rero
Igiciro cya elegitoronike
Kugeza ubu, binyuze mu nganda zayo zo hejuru ku nganda zishobora kumenyekana, kohereza ibiciro bya elegitoronike byarangiye umwaka wose.
Dukurikije isesengura ry'isoko rya Lotupe ya buri gihembwe raporo ya buri gihembwe, miliyoni 190 z'amajwi zoherejwe ku isi mu gihembwe cya mbere cya 2022, hejuru ya 20.5% kuva mu gihe kimwe umwaka ushize. Ku bijyanye n'ibicuruzwa bya elegitoroniki, kohereza ku isi hose ibirango bitatu bya elegitoronike mu gihembwe cya gatatu cya mbere cyageze ku bice miliyoni 180, hamwe n'iterambere ry'umwaka 28.6%.
Ariko e-tags ubu yiruka mu icupa mugushakisha agaciro kiyongereye. Kubera ko ibirango bya elegitoronike biranga ubuzima burebure, bizatwara byibuze imyaka 5-10 kugirango tubisimbuze, ntabwo rero hazabaho gusimburwa imigabane mugihe kirekire, kugirango dushake gusa isoko ryiyongera. Ikibazo, ariko, nuko abadandaza benshi badashaka guhindura ibiciro bya elegitoroniki. Andereya Zigrew Zignani yagize ati: "Bamwe mu batahutse bashidikanya ko tekinoroji ya ESL kubera impungenge zerekeye umucuruzi.
Mu buryo nk'ubwo, ikiguzi nacyo ni ikibazo gikomeye. Nubwo igiciro cyibiciro bya elegitoronike byahinduwe cyane kugirango ugabanye ibiciro byinshi byo kurambirwa, biracyakoreshwa gusa na supermarket nini nka walmart na yonghui mumasoko yagabuwe. Kuri supermarket yumuryango muto, amaduka n'amavuta yoroshye, igiciro cyacyo kiracyafite hejuru. Kandi birakwiye kuvuga ko ibiciro bya elegitoronike nabyo bisabwa gusa kubiduma binini.
Byongeye kandi, ibintu biriho byubu byibiciro bya elegitoronike biraryoroshye. Kugeza ubu, 90% by'ibiciro bya elegitoronike bikoreshwa mu nzego zicururijwe, ariko munsi ya 10% bikoreshwa mu biro, ubuvuzi nibindi bintu. SES-INGETTAG, igihangange mu nganda za digitale, yizera ko igiciro cya digitale kigomba kuba igikoresho cya Emmine kigomba kuba giciro cya omnihanike gishobora gufasha abaguzi no kuzigama abakoresha kandi bakishyura.
Ariko, hariho kandi inkuru nziza kurenza ingorane. Igipimo cyinjira cyibiciro bya elegitoronike mumasoko yimbere mu gihugu ni munsi ya 10%, bivuze ko hakiri isoko ryinshi kugirango bafate. Muri icyo gihe, hamwe no gutegura politiki yo kugenzura icyorezo, kugarura ibiyobyabwenge ni inzira nini, kandi ihagurukira kandi igihe cyiza cyo guhaza ibiciro bya elegitoronike gushaka iterambere ry'isoko. Byongeye kandi, abakinnyi benshi mumirongo yinganda bahimbaza ibiciro bya elegitoronike, abahantu na ses-imagite bafatanya ku giciro cya elegitoroniki. Mugihe kizaza, hamwe no gusaba ikoranabuhanga rihanitse hamwe nuburyo busanzwe, ibiciro bya elegitoronike nabyo bizagira ejo hazaza hashya.
