Ngokutsho kweBluetooth SIG, i-Bluetooth version 5.4 ikhutshwe, izisa umgangatho omtsha weethegi zexabiso le-elektroniki.Kuyaqondwa ukuba uhlaziyo lwetekhnoloji ehambelanayo, kwelinye icala, ithegi yexabiso kwinethiwekhi enye inokwandiswa ukuya kwi-32640, kwelinye icala, isango linokuqonda unxibelelwano lweendlela ezimbini kunye nexabiso lexabiso.
Iindaba zikwabangela ukuba abantu babe nomdla malunga nemibuzo embalwa: Zeziphi izinto ezintsha zobugcisa kwiBluetooth entsha?Yintoni impembelelo ekusetyenzisweni kweethegi zamaxabiso e-elektroniki?Ngaba iya kutshintsha ipateni yemizi-mveliso ekhoyo?Emva koko, eli phepha liza kuxubusha le miba ingentla, indlela yokuphuhliswa kwexesha elizayo leethegi zexabiso le-elektroniki.
Kwakhona, Qaphela iThegi yeXabiso le-Electronic
Ixabiso lexabiso le-elektroniki, i-LCD kunye nesixhobo sokubonisa iphepha lombane elinomsebenzi wokuthumela nokufumana ulwazi, ngonxibelelwano olungenazingcingo ukufezekisa utshintsho lolwazi lwexabiso.Kuba inokungena endaweni yethegi yexabiso lemveli, idityaniswe nokusetyenziswa kwamandla aphantsi (ithegi yexabiso le-inki yesikrini sombane kunye neebhetri ezi-2 ezinokufikelela ngaphezulu kweminyaka emi-5 yonyamezelo), ithandwa luninzi lwabavelisi beevenkile.Okwangoku, isetyenziswe ngokubanzi kwiimveliso zasekhaya nakwamanye amazwe ezaziwayo-kakuhle njengeWal-Mart, Yonghui, Hema Fresh, Mi ekhaya njalo njalo.
Kwaye ithegi yexabiso le-elektroniki ayiyona nje ithegi, kodwa inkqubo yonke emva kwayo.Ngokuqhelekileyo, inkqubo yethegi yexabiso lombane ibandakanya iinxalenye ezine: ithegi yexabiso le-elektroniki (ESL), isikhululo sesiseko esingenazingcingo (ESLAP), i-electronic price tag ye-SaaS inkqubo kunye ne-handheld terminal (PDA).
Umgaqo wokusebenza wenkqubo kukuba: ukuvumelanisa ulwazi lwempahla kunye nexabiso kwi-platform yefu ye-SaaS, kwaye uthumele ulwazi kwithegi yexabiso le-elektroniki ngesikhululo sesiseko se-ESL.Emva kokufumana ulwazi, ithegi yexabiso ingabonisa ulwazi olusisiseko lwempahla efana negama, ixabiso, imvelaphi kunye neenkcukacha ngexesha langempela.Ngokufanayo, ulwazi lwemveliso lungatshintshwa ngaphandle kweintanethi ngokuskena ikhowudi yemveliso nge-PDA ephathwayo ephathwayo.
Phakathi kwabo, ukuhanjiswa kolwazi kuxhomekeke kwiteknoloji yonxibelelwano engenazintambo.Okwangoku, kukho iindlela ezintathu zonxibelelwano eziqhelekileyo ezisetyenziswa kwiithegi zexabiso le-elektroniki: i-433 MHz, i-2.4GHz yangasese, i-Bluetooth, kwaye iprothokholi nganye kwezi zintathu ineenzuzo zayo kunye nokungalunganga.
Ke, iBluetooth yenye yeeprotocol ezisemgangathweni, kodwa enyanisweni, kwimarike, iBluetooth kunye nokusetyenziswa kweprotocol ye-2.4GHz yabucala kuyafana.Kodwa ngoku iBluetooth yethegi yexabiso lombane ukuseka umgangatho omtsha, akukho nzima ukuwubona, kukubamba ithegi yexabiso lombane kule ntengiso yesicelo ngakumbi.
Yintoni entsha ngomgangatho weBluetooth ESL?
Okwangoku, i-radius yokugubungela izikhululo zesiseko se-ESL ziphakathi kwe-30-40 yeemitha, kwaye inani eliphezulu leethegi ezinokuthi zifumaneke zihluka ukusuka kwi-1000-5000.Kodwa ngokutsho kweBluetooth Core Specification Version 5.4 yamva nje, phantsi kwenkxaso yethekhnoloji entsha, inethwekhi inokudibanisa izixhobo ze-32,640 ESL, ngaphezu kokufezekiswa kwezixhobo ze-ESL kunye nesango lonxibelelwano lweendlela ezimbini.
IBluetooth 5.4 ihlaziya amanqaku amabini anxulumene neethegi zexabiso le-elektroniki:
1. Intengiso ngamaxesha athile kunye neeMpendulo (PAwR, intengiso ngamaxesha athile kunye neempendulo)
I-PAwR iya kuvumela ukuphunyezwa kwenethiwekhi yeenkwenkwezi kunye nonxibelelwano lweendlela ezimbini, into eyongeza amandla ezixhobo ze-ESL zokufumana idatha kunye nokuphendula kumthumeli.Ukongezelela, izixhobo ze-ESL zinokwahlulwa zibe ngamaqela amaninzi, kwaye isixhobo ngasinye se-ESL sinedilesi ethile yokwandisa uxhulumaniso kunye nokwenza unxibelelwano lube lunye kunye nolunye ukuya kuninzi.
Kumfanekiso, i-AP ngumsasazi we-PAwR;I-ESL yithegi yexabiso le-elektroniki (yeye-GRPS eyahlukileyo, ene-id eyahlukileyo);i-subevent yi-subevent;rsp slot yimpendulo slot.Kulo mfanekiso, umgca omnyama onqamlekileyo yi-AP yokuthumela imiyalelo kunye neepakethi kwi-ESL, kwaye umgca obomvu onqamlekileyo yi-ESL ephendulayo kunye nokutya kwakhona kwi-AP.
Ngokutsho kwe-Bluetooth Core Specification Version 5.4, i-ESL isebenzisa i-addressing scheme (i-binary) equkethe i-ID ye-8-bit ESL kunye ne-7-bit yeqela.Kwaye i-ID ye-ESL iyingqayizivele kumaqela ahlukeneyo.Ke ngoko, inethiwekhi yesixhobo se-ESL inokuqulatha ukuya kuthi ga kwi-128 amaqela, ngalinye linokuqulatha ukuya kuthi ga kwi-255 yezixhobo ezizodwa ze-ESL ezingamalungu eqela.Ngamagama alula, kunokubakho izixhobo ze-32,640 ze-ESL kwinethiwekhi, kwaye ilebula nganye inokulawulwa ukusuka kwindawo yokufikelela enye.
2. Idatha yeNtengiso eFihliweyo (EAD, idatha yosasazo eFihliweyo)
I-EAD ikakhulu ibonelela ngokusasazwa kwemisebenzi yofihlo lwedatha.Emva kokuba idatha yosasazo iguqulelwe ngokuntsonkothileyo, inokufunyanwa naso nasiphi na isixhobo, kodwa inokukhutshwa kuphela kwaye ingqinwe sisixhobo ebesabelana ngaso ngaphambili ngesitshixo sonxibelelwano.Inzuzo ebalulekileyo yolu phawu kukuba imixholo yeepakethi zokusasaza iyatshintsha njengoko idilesi yesixhobo itshintsha, inciphisa amathuba okulandela umkhondo.
Ngokusekwe kwezi zinto zimbini zingasentla zohlaziyo, iBluetooth iya kuba luncedo ngakumbi kwizicelo zesitikha se-elektroniki.Ngokukodwa xa kuthelekiswa ne-433MHz kunye ne-2.4GHz yangasese, abanayo imigangatho yonxibelelwano yamazwe ngamazwe esebenzayo, ukwenzeka, ukuzinza, ukhuseleko alunakuqinisekiswa ngcono, ngakumbi malunga nokhuseleko, ukukwazi ukucacisa kuya kuba kukhulu.
Ngokufika komgangatho omtsha, ishishini lethegi yexabiso le-elektroniki linokuthi lingenise utshintsho oluthile, ngakumbi abavelisi bemodyuli yonxibelelwano kunye nababoneleli bezisombululo phakathi kwekhonkco leshishini.Kubenzi bezisombululo zeBluetooth, nokuba ngaba ukuxhasa ukuhlaziywa kwe-OTA yeemveliso ezithengiswayo kunye nokuba ukongeza i-Bluetooth 5.4 kumgca omtsha wemveliso ngumbuzo oza kuqwalaselwa.Kwaye kubavelisi beskimu abangengabo-Bluetooth, nokuba ukutshintsha iskimu engundoqo ukusebenzisa Bluetooth kwakhona yingxaki.
Kodwa kwakhona, injani imakethi yexabiso le-elektroniki iphuhla namhlanje, kwaye bubuphi ubunzima?
Ubume bophuhliso lwentengiso yexabiso le-elektroniki kunye nobunzima
Okwangoku, ngokuthunyelwa kwe-e-paper enxulumene noshishino oluphezulu luyakwazi ukwaziwa, ukuthunyelwa kwethegi yexabiso lombane kugqibe ukukhula konyaka nonyaka.
Ngokutsho kweGlobal ePaper Market Analysis Report Quarterly Report, i-190 lezigidi zeemodyuli ze-e-paper zathunyelwa kwihlabathi jikelele kwiikota ezintathu zokuqala zika-2022, zenyuka nge-20.5% ukusuka kwixesha elifanayo kulo nyaka uphelileyo.Ngokubhekiselele kwiimveliso zephepha le-elektroniki, ukuthunyelwa kwehlabathi jikelele kweelebhile ze-elektroniki kwiikota ezintathu zokuqala kufikelele kwi-180 yezigidi zeengcezu, ngokukhula konyaka-ngonyaka ngama-28.6%.
Kodwa ii-e-tags ngoku zibaleka emngciphekweni ekufumaneni ixabiso elongezelelweyo.Ekubeni iileyibhile ze-elektroniki zibonakaliswe kubomi benkonzo ende, kuya kuthatha ubuncinane iminyaka emi-5-10 ukuyibuyisela endaweni, ngoko ke akuyi kubakho ukutshintshwa kwesitokhwe ngexesha elide, ngoko sinokujonga kuphela imarike eyongezelelweyo.Ingxaki, nangona kunjalo, kukuba abathengisi abaninzi bayathandabuza ukutshintshela kwiithegi zexabiso le-elektroniki."Abanye abathengisi baye bathandabuza ukwamkela iteknoloji ye-ESL ngenxa yokukhathazeka malunga nokutshixa umthengisi, ukusebenzisana, ukulinganisa kunye nokukwazi ukukala kwezinye izicwangciso zokuthengisa ezihlakaniphile," kusho u-Andrew Zignani, umlawuli woPhando kwi-ABI Research.
Ngokufanayo, iindleko nazo ziyingxaki enkulu.Nangona ixabiso lethegi yexabiso le-elektroniki lihlengahlengiswe kakhulu ukunciphisa iindleko ezininzi zokubeka, lisasetyenziswa kuphela ziivenkile ezinkulu ezinjengeWalmart kunye neYonghui kwimarike yokuthengisa.Kwiivenkile ezincinci zoluntu, iivenkile eziluncedo kunye neencwadi, ixabiso layo lisephezulu.Kwaye kufanelekile ukukhankanya ukuba iithegi zexabiso ze-elektroniki ziyimfuneko nje kwiivenkile ezingezinkulu.
Ngaphezu koko, iimeko zesicelo zangoku zeethegi zexabiso le-elektroniki zilula.Okwangoku, i-90% yeethegi zexabiso ze-elektroniki zisetyenziswa kwicandelo lokuthengisa, kodwa ngaphantsi kwe-10% isetyenziswe kwiofisi, unyango kunye nezinye iimeko.I-SES-imagotag, i-giant kwi-digital tag tag industry, ikholelwa ukuba i-digital tag tag ayifanele ibe yinto yokubonisa ixabiso, kodwa kufuneka ibe yi-microweb yedatha ye-omnihanatic enokunceda abathengi benze izigqibo zokuchitha kunye nokugcina abaqeshi kunye nabasebenzi ixesha. kunye neendleko.
Nangona kunjalo, kukwakho iindaba ezilungileyo ngaphaya kobunzima.Izinga lokungena kwiithegi zexabiso le-elektroniki kwimarike yasekhaya lingaphantsi kwe-10%, nto leyo ethetha ukuba kusekho urhwebo oluninzi ekufuneka luthengwe.Kwangaxeshanye, ngokulungiswa komgaqo-nkqubo wolawulo lwendyikityha, ukubuyiswa kokusetyenziswa yinto enkulu, kunye nempindezelo yokubuyisela kwicala lokuthengisa nayo iyeza, ekwalithuba elihle leethegi zamaxabiso e-elektroniki ukufuna ukukhula kwemarike.Ngaphezu koko, abadlali abaninzi kwikhonkco loshishino ngokukhutheleyo babeka iithegi zamaxabiso e-elektroniki, i-Qualcomm kunye ne-SES-imagotag ziyasebenzisana kwiithegi zexabiso ze-elektroniki ezisemgangathweni.Kwixesha elizayo, ngokusetyenziswa kwetekhnoloji ephezulu kunye nomkhwa wokulinganisa, iithegi zexabiso le-elektroniki ziya kuba nekamva elitsha.
