Ngokusho kwe-Bluetooth SIG, i-Bluetooth version 5.4 isikhishiwe, okuletha izinga elisha lamathegi amanani e-electronic.Kuyaqondwa ukuthi ukubuyekezwa kobuchwepheshe obuhlobene, ngakolunye uhlangothi, ithegi yentengo kunethiwekhi eyodwa inganwetshwa ibe yi-32640, ngakolunye uhlangothi, isango lingakwazi ukubona ukuxhumana okubili nethegi yamanani.
Lezi zindaba futhi zenza abantu babe nelukuluku lokwazi ngemibuzo embalwa: Yiziphi izinto ezintsha zobuchwepheshe ku-Bluetooth entsha?Uyini umthelela ekusetshenzisweni kwamathegi amanani e-elekthronikhi?Ingabe izoshintsha iphethini ekhona yezimboni?Okulandelayo, leli phepha lizoxoxa ngezindaba ezingenhla, inkambiso yentuthuko yesikhathi esizayo yamathegi entengo kagesi.
Futhi, Bona Ithegi Yentengo Ye-Electronic
Ithegi yentengo ye-elekthronikhi, i-LCD kanye nedivayisi yokubonisa iphepha ye-elekthronikhi enomsebenzi wokuthumela nokwamukela ulwazi, ngokuxhumana okungenantambo ukuze kuzuzwe ushintsho lolwazi lwethegi.Ngenxa yokuthi ingathatha indawo yethegi yentengo evamile, ehambisana nokusetshenziswa kwamandla aphansi (ithegi yentengo kagesi yesikrini sikayinki enamabhethri enkinobho engu-2 ingafinyelela iminyaka engaphezu kwemi-5 yokubekezela), ithandwa iningi labakhiqizi abathengisayo.Njengamanje, isetshenziswe kabanzi ezinkampanini ezithengisa kakhulu ezifuywayo nezangaphandle ezifana ne-Wal-Mart, Yonghui, Hema Fresh, Mi home njalonjalo.
Futhi ithegi yentengo ye-elekthronikhi ayiyona nje umaki, kodwa uhlelo lonke ngemuva kwayo.Ngokuvamile, uhlelo lwethegi yentengo ye-elekthronikhi luhlanganisa izingxenye ezine: ithegi yentengo ye-elekthronikhi (ESL), isiteshi sesisekelo esingenantambo (ESLAP), ithegi yentengo ye-elekthronikhi uhlelo lwe-SaaS kanye nesiphetho esiphathwa ngesandla (PDA).
Isimiso sokusebenza sohlelo sithi: vumelanisa ulwazi lwempahla nolwazi lwamanani kuplathifomu yamafu ye-SaaS, futhi uthumele ulwazi kuthegi yamanani kagesi ngesiteshi sesisekelo se-ESL.Ngemva kokuthola ulwazi, ithegi yentengo ingabonisa ulwazi oluyisisekelo lwempahla njengegama, intengo, imvelaphi kanye nokucaciswa kwesikhathi sangempela.Ngokufanayo, ulwazi lomkhiqizo lungabuye lushintshwe ungaxhunyiwe ku-inthanethi ngokuskena ikhodi yomkhiqizo ngokusebenzisa i-PDA ephathwayo ephathwayo.
Phakathi kwazo, ukudluliswa kolwazi kuncike kubuchwepheshe bokuxhumana obungenawaya.Njengamanje, kunezimiso zokuxhumana ezintathu ezivamile ezisetshenziswa kumathegi amanani e-elekthronikhi: 433 MHz, i-private 2.4GHz, i-Bluetooth, futhi iphrothokholi ngayinye kwezintathu inezinzuzo zayo kanye nokubi.
Ngakho-ke, i-Bluetooth ingenye yezivumelwano ezijwayelekile, kodwa empeleni, emakethe, ukusetshenziswa kwe-Bluetooth kanye ne-2.4GHz yangasese kuyafana.Kodwa manje i-Bluetooth yethegi yamanani kagesi ukusungula indinganiso entsha, akunzima ukuyibona, iwukubamba ithegi yamanani kagesi kule makethe yohlelo lokusebenza.
Yini entsha ngezinga le-Bluetooth ESL?
Njengamanje, irediyasi ekhavayo yeziteshi eziyisisekelo ze-ESL iphakathi kwamamitha angama-30-40, futhi inani eliphezulu lamathegi angakwazi ukufakwa liyahluka ukusuka ku-1000-5000.Kodwa ngokusho kwenguqulo yakamuva ye-Bluetooth Core Specification Version 5.4, ngaphansi kokusekelwa kobuchwepheshe obusha, inethiwekhi ingaxhuma amadivayisi we-32,640 ESL, ngaphezu kokugcwaliseka kwamadivayisi we-ESL kanye nokuxhumana kwesango lokubili.
I-Bluetooth 5.4 ibuyekeza izici ezimbili ezihlobene namathegi entengo kagesi:
1. Ukukhangisa Kwezikhathi Nezimpendulo (PAwR, ukukhangisa ngezikhathi ezithile okunezimpendulo)
I-PAwR izovumela ukusetshenziswa kwenethiwekhi yenkanyezi enokuxhumana okubili, isici esikhulisa amandla edivayisi ye-ESL ukuthola idatha nokuphendula umthumeli.Ngaphezu kwalokho, amadivayisi we-ESL angahlukaniswa ngamaqembu amaningi, futhi idivayisi ngayinye ye-ESL inekheli elithile lokukhulisa ukuxhumana futhi inike amandla ukuxhumana okukodwa kuya kokukodwa nokukodwa kuya kwabaningi.
Esithombeni, i-AP ingumsakazi we-PAwR;I-ESL iyithegi yentengo ye-elekthronikhi (eye-GRPS ehlukene, enama-id ahlukene);i-subevent iyi-subevent;I-rsp slot iyindawo yokuphendula.Emfanekisweni, umugqa ovundlile omnyama yi-AP ethumela imiyalo namaphakethe ku-ESL, futhi umugqa ovundlile obomvu yi-ESL ephendulayo futhi ebuyisela ku-AP.
Ngokwe-Bluetooth Core Specification Version 5.4, i-ESL isebenzisa isikimu samakheli edivayisi (kanambambili) esihlanganisa ama-id angu-8-bit ESL nama-id weqembu angu-7-bit.Futhi i-ID ye-ESL ihlukile emaqenjini ahlukene.Ngakho-ke, inethiwekhi yedivayisi ye-ESL ingaqukatha amaqembu angafika kwangu-128, ngalinye elingaqukatha kufika kumadivayisi angu-255 e-ESL ahlukile amalungu eqembu.Ngamagama alula, kungase kube nengqikithi yamadivayisi angu-32,640 ESL kunethiwekhi, futhi ilebula ngayinye ingalawulwa kusukela endaweni eyodwa yokufinyelela.
2. Idatha Yokukhangisa Ebethelwe (EAD, idatha yokusakaza ebethelwe)
I-EAD ihlinzeka ngokuyinhloko ngemisebenzi yokubethela idatha yokusakaza.Ngemva kokuthi idatha yokusakaza ibetheliwe, ingatholwa inoma iyiphi idivayisi, kodwa ingasuswa ukubethela futhi iqinisekiswe idivayisi eyabelane ngaphambilini ngokhiye wokuxhumana.Inzuzo enkulu yalesi sici ukuthi okuqukethwe kwamaphakethe okusakaza kuyashintsha njengoba ikheli ledivayisi lishintsha, kunciphisa amathuba okulandelela.
Ngokusekelwe ezicini ezimbili ezingenhla zesibuyekezo, i-Bluetooth izoba nenzuzo enkulu ezinhlelweni zesitikha se-elekthronikhi.Ikakhulukazi uma kuqhathaniswa ne-433MHz kanye ne-2.4GHz yangasese, abanayo izindinganiso zokuxhumana ezisebenzayo zomhlaba wonke, ukwenzeka, ukuzinza, ukuvikeleka akukwazi ukuqinisekiswa kangcono, ikakhulukazi mayelana nokuphepha, amathuba okucacisa azoba mkhulu.
Ngokufika kwezinga elisha, imboni yethegi yentengo ye-elekthronikhi ingase futhi ilethe izinguquko ezithile, ikakhulukazi abakhiqizi bemojula yezokuxhumana nabahlinzeki bezixazululo ezindaweni ezimaphakathi zochungechunge lwezimboni.Kubakhiqizi bezixazululo ze-Bluetooth, ukuthi basekele yini izibuyekezo ze-OTA zemikhiqizo ethengisiwe nokuthi bangeze i-Bluetooth 5.4 emugqeni womkhiqizo omusha kuwumbuzo okufanele ucatshangelwe.Futhi kubakhiqizi bezikimu ezingezona eze-Bluetooth, noma ukushintsha isikimu esiyinhloko ukusebenzisa i-Bluetooth nakho kuyinkinga.
Kodwa-ke futhi, imakethe yethegi yentengo kagesi ithuthuka kanjani namuhla, futhi yiziphi izingqinamba?
Isimo sokuthuthukiswa kwemakethe yentengo ye-elekthronikhi nobunzima
Njengamanje, ngokuthunyelwa kwayo okuhlobene ne-e-paper embonini ekhuphukayo kungaziwa, ukuthunyelwa kwethegi yentengo ye-elekthronikhi sekuqede ukukhula konyaka nonyaka.
Ngokombiko we-Lotu's Global ePaper Market Analysis Quarterly Report, amamojula e-e-paper ayizigidi ezingu-190 athunyelwe emhlabeni jikelele ezingxenyeni ezintathu zokuqala zika-2022, akhuphuka ngo-20.5% kusukela esikhathini esifanayo ngonyaka odlule.Mayelana nemikhiqizo yephepha le-elekthronikhi, ukuthunyelwa komhlaba wonke kwamalebula e-elekthronikhi ezingxenyeni ezintathu zokuqala kufinyelele izingcezu eziyizigidi ezingu-180, nokukhula konyaka ngama-28.6%.
Kodwa ama-e-tag manje angena ebhodleleni ekutholeni inani elikhulayo.Njengoba amalebula e-elekthronikhi ebonakala ngokuphila kwesevisi ende, kuzothatha okungenani iminyaka engu-5-10 ukuwashintsha, ngakho-ke ngeke kube khona ukushintshwa kwesitoko isikhathi eside, ngakho-ke singabheka kuphela imakethe ekhulayo.Inkinga, nokho, ukuthi abathengisi abaningi bayanqikaza ukushintshela kumathegi entengo kagesi."Abanye abathengisi bebemanqikanqika ukusebenzisa ubuchwepheshe be-ESL ngenxa yokukhathazeka mayelana nokukhiya komthengisi, ukusebenzisana, ukulinganisa kanye nekhono lokukukala kwezinye izinhlelo zokudayisa ezihlakaniphile," kusho u-Andrew Zignani, umqondisi wocwaningo kwa-ABI Research.
Ngokufanayo, izindleko nazo ziyinkinga enkulu.Nakuba intengo yethegi yentengo ye-elekthronikhi ilungiswe kakhulu ukuze kwehliswe izindleko eziningi zokubeka, isasetshenziswa kuphela izitolo ezinkulu ezifana ne-Walmart ne-Yonghui emakethe yokudayisa.Ezitolo ezinkulu ezincane zomphakathi, izitolo ezidayisa ukudla kanye nezitolo zezincwadi, izindleko zayo zisaphezulu kakhulu.Futhi kufanelekile ukusho ukuthi amathegi amanani e-elekthronikhi nawo ayimfuneko ezitolo ezingezona ezinkulu.
Ngaphezu kwalokho, izimo zokusebenza zamanje zamathegi entengo kagesi zilula uma kuqhathaniswa.Njengamanje, amathegi entengo kagesi angama-90% asetshenziswa emkhakheni wokudayisa, kodwa angaphansi kuka-10% asetshenziswa ehhovisi, ezokwelapha nakwezinye izimo.I-SES-imagotag, umdondoshiya embonini yamanani entengo yedijithali, ikholelwa ukuthi ithegi yentengo yedijithali akufanele nje ibe ithuluzi lokubonisa intengo, kodwa kufanele ibe iwebhu encane yedatha ye-omnihanatic engasiza abathengi benze izinqumo zokusebenzisa imali futhi yonge isikhathi sabaqashi nabasebenzi. kanye nezindleko.
Nokho, kukhona nezindaba ezinhle ngale kobunzima.Izinga lokungena lamathegi entengo ye-elekthronikhi emakethe yasekhaya lingaphansi kuka-10%, okusho ukuthi kusenezimakethe eziningi okufanele zithengwe.Ngasikhathi sinye, ngokulungiswa kwenqubomgomo yokulawula ubhubhane, ukutholwa kabusha kokusetshenziswa kuwumkhuba omkhulu, futhi ukuphindisela okuphindiselayo kohlangothi lwezokuthengisa kuyeza, okuphinde kube yithuba elihle lamathegi entengo kagesi ukufuna ukukhula kwemakethe.Ngaphezu kwalokho, abadlali abaningi ochungechungeni lwemboni babeka amathegi amanani e-elekthronikhi, i-Qualcomm ne-SES-imagotag babambisana kumathegi amanani entengo kagesi.Ngokuzayo, ngokusetshenziswa kobuchwepheshe obuphezulu kanye nokuthambekela kokumiswa, amathegi entengo kagesi nawo azoba nekusasa elisha.
