Ngokwe-Bluetooth sig, uguqulelo lweBluetooth 5.4 lukhutshiwe, luzisa umgangatho omtsha weethegi zexabiso le-elektroniki. Kuyaqondakala ukuba uhlaziyo lwetekhnoloji enxulumene, kwelinye icala, ithegi yexabiso kwinethiwekhi enye inokwandiswa ukuya kuthi ga kwi-32640, kwelinye icala, isango le-thegi yexabiso.
Ezi ndaba zenza ukuba abantu bakwazi ukwazi ukuba banomdla kwimibuzo embalwa: zeziphi izinto ezizobuchwephesha kwiBluetooth entsha? Ithini impembelelo ekusebenzeni kweethegi zexabiso le-elektroniki? Ngaba iyatshintsha ipateni ekhoyo yeshishini? Okulandelayo, eli phepha liza kuthetha ngale micimbi ingentla, imeko yophuhliso lwexesha elizayo yeethegi zexabiso le-elektroniki.
Kwakhona, qaphela ithegi yexabiso le-elektroniki
Ithegi yexabiso le-elektroniki, i-LCD kunye nePhepha le-LCD kunye ne-elektroniki kunye ne-elektroniki kunye nomsebenzi wokuthumela kunye nokufumana ulwazi, ngonxibelelwano olungenazingcingo ukuze kufezekiswe utshintsho lolwazi lwe-tag. Kuba inokutshintsha ithegi ye-ther yendabuko, idityaniswe nokusetyenziswa kwamandla ombane (i-IK screen ye-elektroniki ngeebhetri ezi-2 ze-2 zinokufikelela kwiminyaka engaphezu kwe-5, ithandwa sisininzi sabavelisi abathengisayo. Okwangoku, kuye kwasetyenziswa ngokubanzi kwi-rander yeshishini lasekhaya neliza kwelinye ilizwe elinjenge-Wal-Mart, Yonghui, Hema intsha, i-mi Ho Howay njalo njalo.
Kwaye ithegi yexabiso le-elektroniki ayisiyo ithegi nje, kodwa yinkqubo yonke emva kwayo. Ngokubanzi, inkqubo ye-tag ye-elektroniki ye-elektroniki ibandakanya amacandelo amane: I-tag yexabiso le-elektroniki (i-ESL), isikhululo esingenazingcingo (i-ESLAP), i-STAP ye-EORTAL SYSTAL (PDA).
The operating principle of the system is: synchronize commodity and price information on the SaaS cloud platform, and send information to the electronic price tag through the ESL base station. Emva kokufumana ulwazi, i-tag yexabiso inokubonisa ulwazi olusisiseko lokuthengisa njengegama, ixabiso, imvelaphi kunye nokucaciswa ngexesha lokwenyani. Ngokufanayo, ulwazi lwemveliso lunokutshintshwa ngaphandle kwe-intanethi ngokuskena ikhowudi yemveliso nge-terminal yesandla.
Phakathi kwazo, ukuhanjiswa kolwazi kuxhomekeke kwitekhnoloji yonxibelelwano ngaphandle kwamacingo. Okwangoku, kukho iiprothokholi ezintathu eziphambili ezisetyenziswa kwiithegi zexabiso le-elektroniki: 433 MHZ, i-2.4ghz, iBluetooth, kunye neeprotocols nganye ezintathu zinezibonelelo zayo ezinazo nezingalunganga.
Ke, i-Bluetooth yenye yeeprotokholi ezisemgangathweni, kodwa enyanisweni, kwimarike, iBluetooth kunye ne-Tografi yeProtocol ye-2.4gz ikwangoku. Kodwa ngoku iBluetooth yexabiso le-elektroniki ukumisela umgangatho omtsha, akukho nzima ukubona, kukufaka ixabiso le-elektroniki le ntengiso yentengiso yentengiso.
Yintoni entsha ngomgangatho weBluetooth Esl?
Okwangoku, ukugubungela irediyo yezikhululo zeziseko ze-ESL kungaphakathi kweemitha ezingama-30 ukuya kwengama-40, kunye nelona nani liphezulu leemegi ezinokuthi zifakwe kwi-1000-5000. Kodwa ngokuhambelana nohlobo lwenkcazo yeBluetooth yamva nje yeBluetooth.
I-Bluetooth 5.4 Uhlaziya izinto ezimbini ezinxulumene ne-tag yexabiso le-elektroniki:
1. Intengiso yamaxesha ngamaxesha aneempendulo (i-pawr, intengiso yamaxesha ngamaxesha aneempendulo)
I-Pawr iya kuvumela ukumiliselwa kwenethiwekhi ye-Star eneendlela ezimbini, inqaku elonyusa izixhobo ze-ESL ukufumana idatha kwaye ziphendule kumthumeli. Ukongeza, izixhobo ze-ESL zinokwahlulwa zibe ngamaqela amaninzi, kwaye isixhobo esithile se-ESL sinedilesi yokwandisa unxibelelwano kwaye yenza i-ove-on kunye nonxibelelwano olunye kunye nolwalamano olunye nolwalamano olunye nolwalamano oluninzi.
Emfanekisweni, i-AP ngusasazo we-pawr; I-ESL yithegi yexabiso le-elektroniki (eye yeyabahlukeneyo, kunye ne-IDS eyahlukeneyo); I-Pivevevel yingcali ye-wilive; I-RSP SLOT yi-slot yokuphendula. Kumfanekiso, umgca omnyama othe tyaba yi-PAP kunye neepakethi kwi-ESL, kunye nomgca obomvu othusayo yi-ESL ephendula kwaye ukondla umva kwi-AP.
Ngokweenkcukacha ze-Bluetooth ezingu-5.4, i-ESL isebenzisa iSikimu sokuThintelwa kweSixhobo (Binary) equka izazisi ezi-8 ze-etl kunye ne-ids ye-its kunye ne-id. Kwaye i-ID ye-ESL yahlukile kumaqela ahlukeneyo. Ke ngoko, uthungelwano lwesixhobo se-ESL linokuba namaqela angama-128, ngalinye linokuqulatha kwizixhobo ezingama-255 ezahlukileyo zamalungu eqela. Ngamazwi alula, zinokubakho izixhobo ezingama-32,640 kwinethiwekhi, kwaye ileyibheli nganye inokulawulwa kwindawo enye yokufikelela.
2. Idatha yentengiso efihliweyo (i-EAD, idatha yosasazo efihliweyo)
I-EAD ikakhulu ibonelela ngemisebenzi evuthuzayo. Emva kokuba idatha yosasazo ifihwa, inokufunyanwa nasiphi na isixhobo, kodwa inokufunyanwa kuphela kwaye iqinisekiswe sisixhobo esabelana ngesitshixo sonxibelelwano. Isibonelelo esibalulekileyo seli nqaku kukuba imixholo yeepakethi zosasazo itshintsha njengotshintsho lwedilesi yefowuni, ukunciphisa amathuba okulandelwa.
Ngokusekwe kwezi zinto zimbini zokuhlaziywa, iBluetooth iya kuba yiluncedo ngakumbi kwizicelo ze-elektroniki. Kuthelekisa ngakumbi nge-433mhz kwaye yabucala 2.4ghz, ayinamigangatho yonxibelelwano yaMazwe, ayinamigangatho yonxibelelwano, uzinzo, ukhuseleko alunakuqinisekiswa ngcono, ngakumbi ukubakho komgangatho.
Ngokufika komgangatho omtsha, ishishini le-elektroniki le-elektroniki linokukwenza kwakhona kutshintsho oluthile, ngakumbi abavelisi beemodyuli zonxibelelwano kunye nabanikezeli bemodyuli yonxibelelwano kunye nabanikezeli bemodyuli. Abavelisi bezisombululo ze-Bluetooth, nokuba baxhasa uhlaziyo lwe-OTA lweemveliso ezithengiswayo nokuba ukongeza iBluetooth 5.4 kumgca omtsha wemveliso ngumbuzo ofanele ukuqwalaselwa. Kwaye kubavelisi beskimu seBluetooth, nokuba sitshintshe iziphumo eziphambili zokusebenzisa iBluetooth nayingxaki.
Kodwa emva koko kwakhona, ithini imarike yexabiso le-elektroniki, kwaye bubuphi ubunzima?
I-elektroniki ye-elektroniki ye-elektroniki
Okwangoku, ngokusebenzisa i-E-CAPE yayo ye-E-Iphepha elinayo i-E-Iphepha elinayo linokwaziwa, ukuthunyelwa kwethegi yexabiso le-elektroniki kugqibile ukukhula konyaka.
Ngokukahlaziyo lwe-Lotus Global Global Global Ingxelo yeMakethi yekota, iimodyuli ze-e-2000 zathunyelwa kwihlabathi liphela kwikota yokuqala engama-2022, ukuya kwi-20,5% ukusuka kwixesha elifanayo kunyaka ophelileyo. Ngokwemveliso yephepha le-elektroniki, ukuthunyelwa kweelebheli ze-elektroniki kwiikota ezintathu zokuqala zekota, ukhula lweminyaka eli-28.6%.
Kodwa i-imeyile ngoku isebenza kwibhotile yokufumana ixabiso lokunyusa. Ekubeni iilebheli ze-elektroniki zibonakaliswa ngobomi benkonzo ende, kuyakuthatha iminyaka engama-5 ukuya kweli-10 ukuyifaka endaweni yesethi kwakhona, ke sinokukhangela kuphela kwimakethi yentengiso. Ingxaki, nangona kunjalo, kukuba abathengisi abaninzi bayathandabuza ukutshintshela kwiithegi zexabiso le-elektroniki. "Abanye abathengisi bezingathandeki ukuba bamkele itekhnoloji ye-ESL ngenxa yenkxalabo ye-vendor eliva-ngaphakathi, i-screeling kunye namandla okucwangcisa izicwangciso ze-Smail," watsho u-Andrew Zeignani, umlawuli oPhando ngoPhando.
Kwangokunjalo, iindleko kukwayingxaki enkulu. Nangona ixabiso lethegi yexabiso le-elektroniki lihlengahlengiswe kakhulu ukunciphisa iindleko ezilusuleyo, isasetyenziswa kuphela ziivenkile ezinkulu ezinje nge-walmart kunye ne-yonghui kwimarike yentengiso. Kwiivenkile ezincinci zoluntu, iivenkile ezilula kunye neevenkile zeencwadi, iindleko zayo zisephezulu. Kwaye kufanelekile ukukhankanya ukuba iithegi zamaxabiso ze-elektroniki ziyimfuneko nje yeevenkile ezingekho mthethweni.
Ngapha koko, iimeko zangoku zesicelo ze-elektroniki zexabiso le-elektroniki zilula. Okwangoku, iipesenti ezingama-90 zeethegi zexabiso le-elektroniki zisetyenziswa kwicandelo lokuthengisa, kodwa ngaphantsi kwe-10% lisetyenziswa eofisini, ezonyango kunye nezinye iimeko. I-SES-I-ICEBONIT
Nangona kunjalo, zikho neendaba ezimnandi ngaphaya kobunzima. Ireyithi yokufumana i-Eleclocation yee-elektroniki ze-elektroniki kwimarike yasekhaya ingaphantsi kwe-10%, oko kuthetha ukuba kusekho kwimarike eninzi ekufuneka ifakwe. Kwangelo xesha, kunye nokufumana impumelelo yomgaqo-nkqubo wokulawulwa kwe-Ebhus, ukubuyiselwa kwendlela enkulu, kwaye indawo yokuphinda iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde ibuyele kwi-elektroniki yexabiso le-elektroniki. Ngapha koko, abadlali abaninzi kwi-Shiner Chain babeka ngenkuthalo i-tags yexabiso le-elektroniki, i-SORMCOM kunye ne-Ins-Imas-iMas-Imax iya kubambisana kwiithegi zexabiso le-elektroniki ezimiselweyo. Kwixesha elizayo, ngokusetyenziswa kwetekhnoloji ephezulu kunye nemeko yokubekwa emgangathweni, iithegi zexabiso le-elektroniki ziya kuba nekamva elitsha.
