Amezi abiri ashize, urunigi rwamaduka manini - yo mu Burayi bwamajyepfo yadusabye gusubiramo ibikoresho bya elegitoroniki byerekana ibicuruzwa 22. Itsinda ryabo ryamasoko ryari rimaze gushyirwaho sisitemu eshatu zitandukanye - imwe ikoresha Bluetooth LE, imwe kuri Wi - Fi, indi kuri radio 433 MHz. Buri mucuruzi yavugaga ko ibyabo aribyo byiza. Ntanumwe wasobanuye mubihe byari bibi cyane. Icyo kiganiro cyatwemereye kwandika iki gice.
Imiryango itatu idafite protocole yiganje muri ESL muri iki gihe: Ingufu nke za Bluetooth (BLE, cyane cyane kuva 5.4 zisobanurwa), Wi - Fi, na Sub - GHz radio (433 MHz muri Aziya, 868 MHz i Burayi, 915 MHz muri Amerika y'Amajyaruguru). Buri protocole ikemura ikibazo nyacyo. Buriwese arema ibicuruzwa byabacuruzi badakinisha. Dore ibyo twabonye mububiko nyabwo bwibidukikije.
Bluetooth LE: Fungura Bisanzwe, Biracyakura Mubipimo
Bluetooth ifite imbaraga zikomeye inyuma yayo. Bluetooth SIG yasohoye Umwirondoro wabigenewe wa ESL wubatswe kuri PAwR ya Bluetooth 5.4 (Kwamamaza Ibihe hamwe na Responses) biranga - uburyo butuma umuntu yinjira aho atangariza amabwiriza ibihumbi n'ibirango ahantu hateganijwe, hanyuma akakira ibisubizo adashyizeho umurongo umwe.
Laboratwari ya Silicon yagerageje ibi kuri 1.500 - node muri laboratoire yabo. EM Microelectronic yohereje em|bleu SoC kuri 1.8 × 1.8 mm gusa hamwe na 200 nA ibitotsi byimbitse - bito bihagije kandi bikungahaye bihagije kuburyo byinjira imbere ndetsecompact 2.66 - santimetero E-ink. Hamwe na miliyari zirenga 5 ibikoresho bya Bluetooth byoherezwa buri mwaka, ibiciro byunguka byunguka mubukungu bunini bwikigereranyo.
Ku bacuruzi, ibyiza bifatika ni ibicuruzwa byoroshye. Gufungura bisanzwe bisobanura - byibuze murihame - ko ushobora kuvanga ingingo ziva kumurongo umwe hamwe nibirango biva mubindi. Uku nugusohoka kwingirakamaro kuva kumugurisha ufunga - muribwo bwibasiye ESL kumyaka. Imiyoboro yo gusinzira iri munsi ya 2 µA isanzwe kuri chipeti ya BLE ESL, naho Bluetooth 5.4 igaragaramo ibirango bigera kuri 32,600 kumurongo winjira kumpapuro.
Gufata: "ku mpapuro" bifite akamaro hano. Ibinini binini - byoherejwe kuri BLE biracyari muto ugereranije na sisitemu yihariye imaze imyaka icumi. Rigado, umucuruzi wa IoT ucuruza amarembo akorera muri ESL, ashyira amarembo kugiti cye kumadorari 1000 kugeza 2000 $ yashyizweho - kandi supermarket nini ishobora gukenera icumi cyangwa irenga. BLE ikora kuri 2.4 GHz, igabana spekiteri na Wi - Fi ya router, terefone zabakiriya, microwave, nibindi bikoresho byose bidafite umugozi mu nyubako. Mububiko buhuze, ubwo bwikorezi burashobora gutinza ivugurura ryibiciro mugihe cyamasaha.
Ibyiza bikwiye: farumasi, butike, hamwe nububiko hagati - munsi yububiko bwa 2000 m² - cyane cyane abasanzwe bakoresha urumuri rwa BLE kugirango bakurikirane umutungo. Abacuruzi5.8 - santimetero BLE-ishoboye ibirangoiryo vugurura riva kuri tablet idafite ibikorwa remezo biremereye bizasanga iyi protocole ishimishije.
Wi - Fi: Koresha umuyoboro wawe uriho - Ariko Bije ya Bateri
Ikibanza kiroroshye: ububiko bwawe bumaze gukora uruganda Wi - Fi muri buri kayira, bityo rero simbuka amarembo mashya hanyuma uhuze ESLs yawe kumurongo usanzwe. Kumurongo munini wibigo bimaze gushora imari cyane mubucuruzi bwinjira hamwe nibisobanuro byuzuye, imibare yo guhuza isa neza.
Wi - Fi nayo itanga amakuru menshi kuruta BLE cyangwa Sub - GHz. Izo nyungu zigaragara mugihe urimo usunika ibishushanyo mbonera bikungahaye - amashusho yibicuruzwa, animasiyo yamamaza - kugezaLCD - ishingiye kubiciro bya digitaleaho kuba byoroshye E - ibirango. A.15,6-cm ya LCD ya ecrangukora promotion kuri endcap ikenera umurongo mugari E - wino ibiciro ntabwo.
Ikibazo kigaragara ahantu habiri. Icya mbere, gukoresha ingufu. Wi - Fi ishushanya cyane kurenza BLE cyangwa Sub - GHz muri buri cyiciro cyogukwirakwiza. Ikirango cya E - kuri radiyo Sub - GHz irashobora gukora imyaka itanu kugeza umunani kuri selire yibiceri hamwe namakuru agezweho ya buri munsi. Ikirango kimwe kuri Wi - Fi? Amezi cumi n'abiri kugeza kuri cumi n'umunani. Ku gipimo - ibihumbi n'ibirango mububiko bwinshi - bivuze ko gahunda yo gusimbuza bateri isubiramo itsinda ryanyu rishinzwe gukora. Icya kabiri, urusobe rwinshi. Wi - Fi ESLs irushanwa kuri airtime hamwe na POS ya terefone, ibikoresho byabakiriya, scaneri yabigenewe, hamwe na kiosque yo kugenzura -. Ku wa gatandatu nyuma ya saa sita impinga, ayo marushanwa ntabwo ari theoretical.
Ibyiza bikwiye: abadandaza ba rwiyemezamirimo bafite abakuze, neza - injeniyeri ya Wi - Ibikorwa remezo bya Fi, ububiko bukoresha ibimenyetso bya digitale ya LCD ikoreshwa (aho ubuzima bwa bateri ntaho buhuriye kuko ecran zacometse), hamwe nibikorwa byapimwe mumajana aho kuba ibihumbi icumi.
Sub - GHz (433 / 868 / 915 MHz): Nta Glamour, Urwego rurerure, Bateri ndende
Sub - GHz radio ntabwo ifite urwego rwo kwamamaza rutezimbere nkuko Bluetooth SIG nyampinga BLE. Sisitemu nyinshi Sub - GHz ESL ikoresha protocole yihariye yihariye ikora label. Nta mwirondoro uhari. Guhindura abadandaza bisobanura gusimbuza itumanaho ryose.
Kandi ,, kumiterere yububiko bumwe, physics ihitamo guhitamo neza. Imirongo yo hasi itanga uburebure burebure. Uburebure burebure bwinjira mububiko bwicyuma, urukuta rwibice, hamwe na firigo yerekana firigo neza cyane kuruta ibimenyetso bya GHz 2.4. Erekana Data, Ubwongereza - bushingiye kuri ESL itanga, yubatse urubuga rwabo rwose hafi ya Sub - 1 GHz kubwiyi mpamvu nyine - intera ntarengwa hamwe n’ibimenyetso byinjira mubucuruzi bugoye. Ikintu kimwe Sub - GHz cyo kugeraho gikubiyemo ikirenge kinini cyane kuruta BLE cyangwa Wi-Fi bihwanye. Ahantu ho kugera hasobanura igiciro gito cyibikorwa remezo no gutegura imiyoboro yoroshye.
Ubuzima bwa Batteri nibindi bintu byingenzi. Igishushanyo mbonera cya Silicon Labs cyerekana ko kugera ku myaka itanu kugeza ku icumi ku kagari ka CR2032 bisaba ingengo yimari iri munsi ya 10 µA - Sub - GHz FG22 SoC igera kuri 0.17 µA mu gusinzira cyane. Kuribinini - imiterere E - ibirango bya winomububiko cyangwa hypermarket ibidukikije hamwe namakuru agera kuri atatu kumunsi, Sub - GHz ihora itanga ubuzima burebure.
Ibyiza bikwiye: hypermarkets hamwe nini - abadandaza agasanduku kari hejuru ya m² 5000, ububiko nububiko bwibikoresho hamwe no gutondagura ibyuma, urunigi rukonje hamwe n’ahantu hakonjeshwa, hamwe nogukoresha aho kugabanya ibikorwa remezo no gukoresha ubuzima bwa bateri bifata umwanya munini kuruta umurongo mugari. Abakiriya bacu basohora E - ibirango bya wino hejuru yububiko bunini - ububiko bwimiterere burigihe bikurura Sub - GHz.

Guhitamo Porotokole Binyuze mububiko bwawe bwose
Ikintu cyo kugereranya protocole ingingo zihora zibura: umuyoboro wawe wa ESL udakorera wenyine. Ingingo zo kwinjira, ibiciro byinyuma, software yo kuyobora - byose bikora ku zindi sisitemu ya digitale mububiko. Niba uri kwirukakwikorera - serivisi ya touchscreen ya kiosquekuri cheque, izo kiosque zikurura ibiciro mububiko bumwe. Niba akabati - inkingi ya LCD yerekana ibikorwa byamamaza mu kayira, moteri yibirimo igaburira izo ecran irashobora kandi gukangura ubukangurambaga kuri label yawe ya E - wino - ariko gusa iyo sisitemu isangiye urwego rusange rwa API.
Twabonye ibisubizo bisukuye mugihe abakiriya bateganya gahunda yabo ya ESL hamwe na kiosk yabo hamwe nibyapa bya digitale, ntabwo ari imishinga itatu itandukanye ya IT. Iyo igiciro umukiriya abonye kuri tagi ya tekinike, ecran ya LCD ya ecran, hamwe na - igenzura rya terefone yose igaburira isoko imwe, kugena ibiciro - ingingo imwe nini yo guterana amagambo mu biribwa - igabanuka hafi ya zeru.
Ibibazo bitatu mbere yo kwiyemeza
Gahunda yawe yo hasi isa ite?Farumasi ya 400 m² na hypermarket ya 12,000 ni ibidukikije bitandukanye bya radio. BLE ikora iyambere hamwe na bibiri cyangwa bitatu byo kugera. Iya kabiri birashoboka ko ikeneye Sub - GHz kugirango wirinde kwangiza igisenge hamwe namarembo.
Ni ibihe bintu urimo kwerekana?Ibiciro bihamye kuri E - wino? Porotokole iyo ari yo yose ikemura ibyo. Kwamamaza amashusho kuri ecran ya LCD? Ukeneye Wi - Fi yinjira. Igiciro cya Flash gihinduka inshuro nyinshi kumasaha? Emeza protocole yawe irashobora gukomeza amajwi agezweho udakuyemo bateri imburagihe.
Niki kindi gisangira umuyaga wawe?Ububiko bumaze kuzura kuri 2,4 GHz - umukiriya Wi - Fi, ibyuma bya IoT, ibyuma bifata ibyuma - bizahangana na sisitemu ya 2.4 GHz yashyizwe hejuru. Sub - GHz ikorera mumatsinda make yuzuye.
Nta protocole imwe nimwe nziza kwisi yose. Niba utanga ESL atanga gusa inzira imwe idafite umugozi kandi ntashobora gusobanura aho iguye, ibyo bikubwira ikintu. Niba ushaka kugerageza ibirango kuri protocole mububiko bwawe nyabwo mbere yo gukora ku gipimo,gusaba icyitegererezo- ibyumweru bibiri munzira imwe nzima irerekana ibirenze urupapuro urwo arirwo rwose cyangwa igicuruzwa cyerekana ibicuruzwa.
