Zvinoenderana neBluetooth SIG, Bluetooth vhezheni 5.4 yakaburitswa, ichiunza chiyero chitsva chemagetsi emitengo.Zvinonzwisiswa kuti iyo yekuvandudza tekinoroji yakabatana, kune rumwe rutivi, mutengo weti mune imwechete network inogona kuwedzerwa kusvika ku32640, kune rumwe rutivi, gedhi rinogona kuona nzira mbiri dzekutaurirana nemutengo tag.
Nhau zvakare dzinoita kuti vanhu vade kuziva nezvemibvunzo mishoma: Ndeapi magadzirirwo ehunyanzvi muBluetooth nyowani?Chii chinokanganisa pakushandiswa kwema tag emitengo yemagetsi?Ichachinja maitiro eindasitiri aripo here?Zvadaro, pepa iri richakurukura nyaya dziri pamusoro apa, remangwana rekusimudzira maitiro emagetsi ematengo emagetsi.
Zvekare, Ziva iyo Electronic Price Tag
Electronic mutengo tag, LCD uye yemagetsi bepa kuratidza mudziyo une basa rekutumira uye kugamuchira ruzivo, kuburikidza newireless kutaurirana kuti uwane mutengo weti yekuchinja ruzivo.Nekuti inogona kutsiva iyo yechinyakare mutengo tag, pamwe nekushomeka kwemagetsi kushandiswa (inki skrini yemagetsi mutengo tag ine 2 bhatani mabhatiri inogona kuwana anopfuura makore mashanu ekutsungirira), inofarirwa neruzhinji rwevagadziri vezvitoro.Parizvino, yakashandiswa zvakanyanya mumabhizimusi epamba uye ekunze anozivikanwa bhizinesi rekutengesa mhando seWal-Mart, Yonghui, Hema Fresh, Mi kumba uye zvichingodaro.
Uye yemagetsi mutengo tag haisi kungoita tag, asi system yese kumashure kwayo.Kazhinji, yemagetsi mutengo tag system inosanganisira zvikamu zvina: yemagetsi mutengo tag (ESL), isina waya base station (ESLAP), yemagetsi mutengo tag SaaS system uye handheld terminal (PDA).
Iyo yekushandisa musimboti weiyo system ndeye: wiriranisa commodity uye mutengo ruzivo paSaaS cloud platform, uye tumira ruzivo kune yemagetsi mutengo tag kuburikidza neESL base station.Mushure mekugamuchira ruzivo, iyo teki yemutengo inogona kuratidza ruzivo rwekutanga senge zita, mutengo, mabviro uye yakatarwa munguva chaiyo.Saizvozvo, ruzivo rwechigadzirwa runogonawo kuchinjirwa kunze kwenyika nekutarisa kodhi yechigadzirwa kuburikidza neyakabata ruoko terminal PDA.
Pakati pavo, kufambiswa kwemashoko kunoenderana newaya isina waya yekutaurirana tekinoroji.Parizvino, kune matatu makuru ekutaurirana maprotocol anoshandiswa pamatengo emitengo yemagetsi: 433 MHz, yakavanzika 2.4GHz, Bluetooth, uye imwe neimwe yemapuroteni matatu ine zvayakanakira nezvayakaipira.
Saka, Bluetooth ndeimwe yeakanyanya kujaira mapuroteni, asi kutaura zvazviri, mumusika, Bluetooth uye yakavanzika 2.4GHz protocol kushandiswa kwakafanana.Asi ikozvino Bluetooth yemagetsi mutengo tag kumisa chiyero chitsva, haina kuoma kuona, ndeyekutora yemagetsi mutengo tag iyi application market more.
Chii chitsva neBluetooth ESL standard?
Parizvino, iyo yekuvhara radius yeESL base zviteshi iri pakati pe30-40 metres, uye huwandu hwepamusoro hwemategi anogona kugariswa anosiyana kubva pa1000-5000.Asi maererano neazvino Bluetooth Core Specification Version 5.4, pasi perutsigiro rwetekinoroji nyowani, network inogona kubatanidza 32,640 ESL zvishandiso, mukuwedzera pakuzadzikiswa kwemidziyo yeESL uye gedhi nzira mbiri dzekutaurirana.
Bluetooth 5.4 inogadziridza maviri maficha ane chekuita nemagetsi mutengo tags:
1. Periodic Advertising with Responses (PAwR, periodic advertising nemhinduro)
PAwR inobvumira kuisirwa nyeredzi network ine nzira mbiri dzekukurukurirana, chinhu chinowedzera kugona kweESL zvishandiso kugamuchira data uye kupindura kune anotumira.Pamusoro pezvo, zvishandiso zveESL zvinogona kukamurwa kuita mapoka akawanda, uye imwe neimwe ESL mudziyo une kero chaiyo yekuwedzera kubatana uye kugonesa imwe-kune-imwe uye imwe-kune-vakawanda kutaurirana.
Pamufananidzo, AP ndiye PAwR nhepfenyuro;ESL itegi yemutengo wemagetsi (yeGRPS yakasiyana, ine maid akasiyana);subevent is a subevent;rsp slot ndiyo inopindura slot.Mumufananidzo, mutsara wakasviba wakatwasuka ndiyo AP inotumira mirairo uye mapaketi kuESL, uye mutsara mutsvuku wakatwasuka ndiyo ESL inopindura uye ichidyisa kuAP.
Zvinoenderana neBluetooth Core Specification Version 5.4, ESL inoshandisa kero kero yemudziyo (binary) ine 8-bit ESL ids uye 7-bit boka ids.Uye iyo ESL ID yakasarudzika mumapoka akasiyana.Naizvozvo, iyo ESL mudziyo network inogona kuve nemapoka anosvika zana nemakumi maviri nemasere, rimwe nerimwe rinogona kunge riine anosvika mazana maviri nemakumi mashanu neshanu emidziyo yeESL yenhengo dzeboka.Nemashoko akareruka, panogona kunge paine huwandu hwe32,640 ESL zvishandiso mune network, uye yega label inogona kudzorwa kubva kune imwechete yekuwana nzvimbo.
2. Yakavharidzirwa Advertising Data (EAD, Encrypted nhepfenyuro data)
EAD inonyanya kupa nhepfenyuro yedata encryption mabasa.Mushure mekunge data rekutepfenyura ravharwa, rinogona kugamuchirwa nechero mudziyo, asi rinogona kungodzikiswa nekusimbiswa nemudziyo wakambogovana kiyi yekutaurirana.Kubatsira kwakakosha kwechinhu ichi ndechekuti zviri mukati memapaketi ekutepfenyura zvinoshanduka sezvo kero yemudziyo inochinja, zvichideredza mukana wekutevera.
Zvichienderana nezviri pamusoro apa maficha ekuvandudza, Bluetooth ichave yakakosha mune zvemagetsi sticker application.Kunyanya kana ichienzaniswa ne433MHz uye yakavanzika 2.4GHz, ivo havana yepasirese inoshanda yekutaurirana zviyero, practicability, kugadzikana, chengetedzo haigone kuvimbiswa zviri nani, kunyanya maererano nechengetedzo, mukana wekududzira uchava mukuru.
Nekusvika kweiyo chiyero chitsva, indasitiri yemitengo yemitengo yemagetsi inogona zvakare kuunza shanduko dzakati, kunyanya vagadziri vemodule yekukurukurirana uye vanopa mhinduro vari pakati pekusvika kweindasitiri cheni.Kune vagadziri veBluetooth mhinduro, vangave kutsigira OTA zvigadziriso zvezvakatengeswa zvigadzirwa uye kana kuwedzera Bluetooth 5.4 mumutsara wechigadzirwa mutsva mubvunzo unofanirwa kutariswa.Uye kune vasiri-Bluetooth scheme vagadziri, kana kuchinja musimboti hurongwa kushandisa Bluetooth zvakare idambudziko.
Asi zvakare zvakare, musika wemagetsi mutengo wekutengesa urikudziridzika sei nhasi, uye ndeapi matambudziko?
Electronic mutengo tag musika kusimudzira mamiriro uye matambudziko
Parizvino, kuburikidza neayo ekumusoro indasitiri e-pepa ane chekuita nekutumira anogona kuzivikanwa, kutakura kwemagetsi mutengo tag kwapedza gore-ne-gore kukura.
Zvinoenderana neLotu's Global ePaper Market Analysis Quarterly Report, 190 miriyoni e-mapepa module akatumirwa pasi rose muzvikamu zvitatu zvekutanga zve2022, kusvika 20.5% kubva panguva imwecheteyo gore rapfuura.Panyaya yezvigadzirwa zvemapepa emagetsi, kutumirwa kwepasi rose kwemavara emagetsi muzvikamu zvitatu zvekutanga kwakasvika zvidimbu zvemamiriyoni e180, nekukura kwegore negore kwe28,6%.
Asi mae-tag ave kumhanya mubhodhoro mukutsvaga kuwedzera kukosha.Sezvo zvinyorwa zvemagetsi zvichiratidzwa nehupenyu hurefu hwebasa, zvinotora makore angangoita 5-10 kuti azvitsive, saka hapazove nekutsiviwa kwemasheya munguva yakareba, saka tinogona kungotsvaga musika wekuwedzera.Dambudziko, zvisinei, nderekuti vatengesi vazhinji vanozeza kushandura kumatengo emitengo yemagetsi."Vamwe vatengesi vanga vachizeza kutora tekinoroji yeESL nekuda kwekunetsekana nezvekuvhara-mukati kwevatengesi, kudyidzana, scalability uye kugona kuikwidza kune zvimwe zvirongwa zvekutengesa zvakangwara," akadaro Andrew Zignani, Director weKutsvagisa kuABI Research.
Saizvozvowo, mari idambudziko guru.Kunyangwe mutengo wemagetsi mutengo tag wakagadziridzwa zvakanyanya kudzikisa yakawanda yekuisa mutengo, uchiri kungoshandiswa nezvitoro zvikuru seWalmart neYonghui mumusika wekutengesa.Kune zvitoro zvidiki zvenharaunda, zvitoro zviri nyore uye zvitoro zvemabhuku, mutengo wayo uchiri wakakwira.Uye zvakakosha kuti titaure kuti ma tag emutengo wemagetsi anongori chinodikanwa kune zvisiri-hombe zvitoro.
Uyezve, mamiriro ezvino ekushandisa emagetsi emitengo tags ari nyore.Parizvino, 90% yematengo emagetsi emitengo anoshandiswa munharaunda yekutengesa, asi isingasviki 10% inoshandiswa muhofisi, kurapwa uye mamwe mamiriro.SES-imagotag, hofori muindasitiri yemitengo yedhijitari, inotenda kuti teki yemutengo wedhijitari haifanire kungova chishandiso chekuratidza mutengo, asi inofanirwa kuve microweb yeomnihanatic data inogona kubatsira vatengi kuita sarudzo dzekushandisa uye kuchengetedza vashandirwi nevashandi nguva. uye mutengo.
Zvisinei, kunewo mashoko akanaka kupfuura matambudziko.Mwero wekupinda wemagetsi emitengo tags mumusika wepamba uri pasi pe10%, zvinoreva kuti kuchine musika wakawanda unofanirwa kubatwa.Panguva imwecheteyo, nekugadzirisa kweiyo denda rekudzora mutemo, kudzoreredza kwekushandisa itsika hombe, uye kudzoreredza kudzoreredzwa kwedivi rekutengesa kuri kuuyawo, unovawo mukana wakanaka wematengo emitengo yemagetsi kutsvaga kukura kwemusika.Uyezve, vatambi vakawanda muindasitiri yeketani vari kushingaira kuisa ma tag emitengo yemagetsi, Qualcomm uye SES-imagotag vari kushandirapamwe pamatagi emitengo yemagetsi.Mune ramangwana, nekushandiswa kwehunyanzvi hwepamusoro uye maitiro ekumisikidza, emagetsi mutengo ma tag achavewo neramangwana idzva.
