Sekureva kweBluetooth SIG, Bluetooth version 5.4 yaburitswa, zvichiunza mwero mutsva wematag emitengo yemagetsi. Zvinonzwisisika kuti kuvandudzwa kwetekinoroji ine chekuita nayo, kune rumwe rutivi, tag yemutengo mune imwe network inogona kuwedzerwa kusvika ku32640, kune rumwe rutivi, gateway inogona kuita kutaurirana kwenzira mbiri netag yemutengo.
Nhau idzi dzinoitawo kuti vanhu vade kuziva mibvunzo mishoma: Ndezvipi zvinhu zvitsva zviri muBluetooth itsva? Chii chiri kukanganisa kushandiswa kwematagi emitengo yemagetsi? Zvichachinja here maitiro aripo emaindasitiri? Tevere, bepa iri richakurukura nyaya dziri pamusoro apa, mafambiro ekuvandudza emategi emitengo yemagetsi mune ramangwana.
Zvakare, Ziva Mutengo weElectronic Tag
Chiratidzo chemutengo wemagetsi, LCD nechinhu chemagetsi chinoratidza mapepa chine basa rekutumira nekugamuchira ruzivo, kuburikidza nekutaurirana kusina waya kuti ruzivo rwemutengo ruchinje. Nekuti chinogona kutsiva chiratidzo chemutengo wekare, pamwe chete nekushandiswa kwesimba shoma (chiratidzo chemutengo wemagetsi cheinki chine mabhatiri maviri chinogona kutsungirira kwemakore anopfuura mashanu), chinofarirwa nevazhinji vevagadziri vezvitoro. Parizvino, chave chichishandiswa zvakanyanya mumabhizinesi emuno nekunze kwenyika anozivikanwa ekutengesa zvinhu zvakaita seWal-Mart, Yonghui, Hema Fresh, Mi home nezvimwewo.
Uye tag yemutengo wemagetsi haisi tag chete, asi sisitimu yese iri shure kwayo. Kazhinji, sisitimu ye tag yemutengo wemagetsi inosanganisira zvikamu zvina: tag yemutengo wemagetsi (ESL), chiteshi chemagetsi che wireless (ESLAP), tag yemutengo wemagetsi yeSaaS system uye terminal inobatwa nemaoko (PDA).
Nheyo yekushanda kwesystem iyi ndeiyi: batanidza ruzivo rwezvinhu nemitengo papuratifomu yeSaaS cloud, uye tumira ruzivo kune tag yemutengo wemagetsi kuburikidza neESL base station. Mushure mekugamuchira ruzivo, tag yemutengo inogona kuratidza ruzivo rwezvinhu zvekutanga senge zita, mutengo, kwakabva uye zvakatsanangurwa munguva chaiyo. Saizvozvowo, ruzivo rwechigadzirwa runogonawo kuchinjwa pasina internet nekuskena kodhi yechigadzirwa kuburikidza nePDA inobatwa neruoko.
Pakati pazvo, kutapurirana kwemashoko kunoenderana netekinoroji yekutaurirana isina waya. Parizvino, kune nzira nhatu huru dzekutaurirana dzinoshandiswa pamatagi emitengo yemagetsi: 433 MHz, 2.4GHz yemunhu, Bluetooth, uye imwe neimwe yenzira nhatu idzi ine zvayakanakira nezvayakaipira.
Saka, Bluetooth ndeimwe yemitemo yakajairika, asi kutaura zvazviri, pamusika, kushandiswa kweBluetooth neprotocol ye 2.4GHz yega kwakafanana. Asi ikozvino Bluetooth kuti tag yemutengo wemagetsi igadzire chiyero chitsva, hazvisi zvakaoma kuona, ndeyekutora tag yemutengo wemagetsi mumusika weapplication iyi zvakanyanya.
Chii chitsva neBluetooth ESL standard?
Parizvino, nzvimbo yekufukidza nzvimbo dzeESL dziri pakati pemamita makumi matatu kusvika makumi mana, uye huwandu hwepamusoro hwematag anogona kuiswa hunosiyana kubva pa1000 kusvika ku5000. Asi zvichienderana neBluetooth Core Specification Version 5.4 yazvino, pasi perutsigiro rwetekinoroji itsva, network inogona kubatanidza 32,640 ESL devices, pamusoro pekuzadzikiswa kweESL devices uye gateway two-way communication.
Bluetooth 5.4 inovandudza zvinhu zviviri zvine chekuita nematagi emitengo yemagetsi:
1. Kushambadzira Nguva Nenguva Nemhinduro (PAwR, kushambadzira nguva nenguva nemhinduro)
PAwR ichabvumira kushandiswa kwenetiweki yenyeredzi ine kutaurirana kwenzira mbiri, chinhu chinowedzera kugona kwemidziyo yeESL kugamuchira data nekupindura kune anotumira. Pamusoro pezvo, michina yeESL inogona kukamurwa kuita mapoka akawanda, uye mudziyo wega wega weESL une kero chaiyo yekuwedzera kubatana uye kugonesa kutaurirana kwemunhu mumwe nemumwe uye kwemunhu mumwe chete.
Mumufananidzo, AP ndiyo nhepfenyuro yePAwR; ESL ibheji remutengo wemagetsi (rinobva kuGRPS dzakasiyana, rine maID akasiyana); subevent ipfupiso; rsp slot ndiyo nzvimbo yekupindura. Mumufananidzo, mutsetse mutema wakatambanuka ndiwo AP inotumira mirairo nemapaketi kuESL, uye mutsetse mutsvuku wakatambanuka ndiwo ESL inopindura uye inodzosera kuAP.
Zvichienderana neBluetooth Core Specification Version 5.4, ESL inoshandisa chirongwa che addressing che device (binary) chine 8-bit ESL ids uye 7-bit group ids. Uye ESL ID yakasiyana mumapoka akasiyana. Nokudaro, network yeESL device inogona kuva nemapoka anosvika 128, rimwe nerimwe rayo rinogona kuva nemidziyo yeESL inosvika 255 yakasiyana yenhengo dzeboka. Muchidimbu, panogona kunge paine midziyo yeESL inosvika 32,640 munetwork, uye label yega yega inogona kudzorwa kubva panzvimbo imwe chete yekupinda.
2. Data reKushambadzira Rakavanzika (EAD, Data reKushambadzira Rakavanzika)
EAD inonyanya kupa mabasa ekudzivirira data rekutepfenyura. Mushure mekunge data rekutepfenyura ravharwa, rinogona kugamuchirwa nechero mudziyo, asi rinogona chete kubviswa crypt uye kusimbiswa nemudziyo waimbogovana kiyi yekutaurirana. Kubatsira kukuru kwechinhu ichi ndechekuti zviri mumapaketi ekutepfenyura zvinochinja sezvo kero yemudziyo ichichinja, zvichideredza mukana wekutevera.
Zvichibva pazvinhu zviviri zviri pamusoro apa zvekuvandudzwa, Bluetooth ichave inobatsira zvikuru mukushandiswa kwezvishandiso zvemagetsi. Kunyanya kana zvichienzaniswa ne433MHz ne2.4GHz yega, hadzina mitemo yekutaurirana yepasi rose inoshanda, kushanda kwayo, kugadzikana, uye kuchengetedzeka hazvigone kuvimbiswa zviri nani, kunyanya panyaya yekuchengetedzwa, mukana wekunzwisisa uchava mukuru.
Nekusvika kwemuyero mutsva, indasitiri yemagetsi inogonawo kuunza shanduko dzakati wandei, kunyanya vagadziri vemamodule ekutaurirana nevapi vemhinduro vari pakati pecheni yeindasitiri. Kune vagadziri veBluetooth solutions, kana vachitsigira OTA updates yezvigadzirwa zvinotengeswa uye kana vachiisa Bluetooth 5.4 mumutsara mutsva wechigadzirwa inyaya inofanirwa kufungwa nezvayo. Uye kune vagadziri vasiri veBluetooth scheme, kana vachichinja core scheme kuti vashandise Bluetooth idambudzikowo.
Asi zvakare, musika wemagetsi uri kukura sei nhasi, uye matambudziko aripo ndeapi?
Mamiriro ekugadzirwa kwemusika wemagetsi uye matambudziko
Parizvino, kuburikidza nekutumira zvinhu zvine chekuita nepepa remagetsi muindasitiri yepamusoro, mutengo wezvinhu zvemagetsi wasvika pakukura kwegore negore.
Sekureva kweLotu's Global ePaper Market Analysis Quarterly Report, ma e-paper modules emamiriyoni zana nemakumi mapfumbamwe akatumirwa pasi rose muzvikamu zvitatu zvekutanga zvegore ra2022, zvichikwira ne20.5% kubva panguva imwe cheteyo gore rapfuura. Panyaya yezvigadzirwa zvema e-mail, kutumirwa kwepasi rose kwema labels emagetsi muzvikamu zvitatu zvekutanga kwakasvika zvidimbu zvemamiriyoni zana nemakumi masere, nekukura kwegore negore kwe28.6%.
Asi ma e-tags ari kusangana nematambudziko pakutsvaga kukosha kwakawedzerwa. Sezvo ma electronic labels achiratidzwa nehupenyu hurefu hwebasa, zvinotora makore angangoita mashanu kusvika gumi kuti atsiviwe, saka hapazovi nekutsiviwa kwemasheya munguva refu, saka tinogona kungotsvaga musika wekuwedzera. Dambudziko, zvisinei, nderekuti vatengesi vazhinji havadi kuchinja kune ma electronic price tags. "Vamwe vatengesi vanga vachizeza kushandisa tekinoroji yeESL nekuda kwekunetseka nezvekuvharirwa kwevatengesi, kushanda pamwe chete, kukura uye kugona kuiwedzera kune mamwe mapurani ekutengesa akangwara," akadaro Andrew Zignani, director weResearch kuABI Research.
Saizvozvowo, mutengo idambudziko guru. Kunyangwe mutengo wemutengo wemagetsi wagadziriswa zvakanyanya kuti uderedze mari yakawanda yekuisa zvinhu, uchiri kungoshandiswa nemasupamaketi makuru akadai seWalmart neYonghui mumusika wekutengesa. Kune masupamaketi madiki emunharaunda, zvitoro zvekutengesa zvinhu zviri nyore uye zvitoro zvemabhuku, mutengo wawo uchiri wakakwira. Uye zvakakosha kutaura kuti mitengo yemagetsi inongovawo chinhu chinodiwa muzvitoro zvisiri zvikuru.
Uyezve, mamiriro ekushandiswa kwazvino kwema "electronic price tag" ari nyore. Parizvino, 90% yema "electronic price tag" anoshandiswa muzvitoro, asi ari pasi pe10% anoshandiswa muhofisi, mune zvehutano uye mune zvimwe zviitiko. SES-imagotag, kambani hombe muindasitiri yema "digital price tag", inotenda kuti "digital price tag" haifanirwe kungova chishandiso chekuratidza mitengo chete, asi inofanira kuva microweb yedata re omnihanatic rinogona kubatsira vatengi kuita sarudzo dzekushandisa mari uye kuchengetedza vashandirwi nevashandi nguva nemari.
Zvisinei, kunewo mashoko akanaka kunze kwematambudziko. Kupinda kwematagi emitengo yemagetsi mumusika wemuno kuri pasi pe10%, zvinoreva kuti kuchine musika wakawanda wekushandisa. Panguva imwe chete, nekuvandudzwa kwemutemo wekudzora denda, kudzoreredzwa kwekushandiswa kwemari itsika huru, uye kudzoserwa kwemari yekutengeserana kuri kuuyawo, izvo zvakare mukana wakanaka wekuti matagi emitengo yemagetsi atsvage kukura kwemusika. Uyezve, vatambi vakawanda muindasitiri vari kushanda nesimba kugadzira matagi emitengo yemagetsi, Qualcomm neSES-imagotag vari kushanda pamwe chete pamatagi emitengo yemagetsi akajairwa. Mune ramangwana, nekushandiswa kwetekinoroji yepamusoro uye maitiro ekuenzanisa, matagi emitengo yemagetsi achavawo neramangwana idzva.
