Ma tag ochulukirapo a RFID a mulungu wama tag a RFID!
Kuyambira kufalitsidwa Pafupifupi zaka 7 zapita. Za izi , chiwerengero chachikulu cha ma tag a RFID ndi makhadi anzeru apeza m'matumba anga: makhadi otetezedwa (mwachitsanzo, zilolezo kapena makhadi aku banki), kupita ku ski, kupita kwapagulu, popanda zomwe ku Netherlands kwina ndizosatheka kukhala popanda, ndiye china. .
Nthawi zambiri, ndi nthawi yoti mukonzenso gulu lonseli lomwe limaperekedwa ku KDPV. M'nkhani zatsopano za RFID ndi makadi anzeru, ndipitiliza nkhani yanthawi yayitali yokhudzana ndi msika, ukadaulo ndi mawonekedwe amkati mwawowonadi. micro-chips, popanda zomwe moyo wathu watsiku ndi tsiku sungathenso kuganiza, kuyambira pakuwongolera kayendedwe ka katundu (mwachitsanzo, ) ndi kutha ndi kumanga nyumba zosanjikizana. Kuphatikiza apo, panthawiyi osewera atsopano (mwachitsanzo, achi China) abwera, kuwonjezera pa otopa zomwe ndi zofunika kuziyankhula.
Monga mwachizolowezi, nkhaniyo igawidwa m'magawo ammutu, omwe ndiyika molingana ndi mphamvu zanga, kuthekera kwanga komanso mwayi wopeza zida.
Maulosi
Chifukwa chake, ndikofunikira kukumbukira kuti zidziwitso zotsegulira kwa ine zinali kupitiriza ntchito yanga yogwiritsa ntchito ma electron microscopy ndi kudula. kumbuyo mu 2012. MU Lingaliro la magwiridwe antchito a ma tag a RFID lidawunikiridwanso mwachidule, ndipo ma tag angapo odziwika komanso omwe analipo panthawiyo adatsegulidwa ndi kupasuka.
Mwina pali zochepa zomwe zitha kuwonjezeredwa ku nkhaniyi lero: 3 (4) yofananira miyezo yodziwika bwino LF (120-150 kHz), HF (13.65 MHz - ma tag ambiri amagwira ntchito mosiyanasiyana), UHF (kwenikweni, pali ma frequency awiri 433 ndi 866 MHz), omwe amatsatiridwa ndi ; mfundo zomwezo zogwirira ntchito - kuyambitsa magetsi ku chip ndi mafunde a wailesi ndikukonza chizindikiro chomwe chikubwera ndikutulutsa chidziwitso kwa wolandila.
Nthawi zambiri, tag ya RFID imawoneka motere: gawo lapansi, mlongoti, ndi chip palokha.
Tag-it kuchokera ku Texas Instruments
Komabe, "malo" ogwiritsira ntchito ma tag awa m'moyo watsiku ndi tsiku asintha kwambiri.
Ngati mu 2012 NFC () chinali chinthu chachilendo mu foni yamakono, zomwe sizinali zomveka bwino momwe zingagwiritsidwe ntchito komanso komwe zingagwiritsidwe ntchito. Ndipo zimphona monga Sony, mwachitsanzo, adalimbikitsa NFC ndi RFID ngati njira yolumikizira zipangizo (wokamba nkhani kuchokera ku Sony Xperia yoyamba, yomwe imagwirizanitsa mwamatsenga ndi kukhudza foni - Oo! Zodabwitsa!) ndikusintha mayiko (mwachitsanzo, adabwera kunyumba, adagwedeza chizindikirocho, foni idatsegula phokoso, yolumikizidwa ndi WiFi, ndi zina zotero), zomwe, mwa lingaliro langa, sizinali zotchuka kwambiri.
Kenako mu 2019, ndi aulesi okhawo omwe sagwiritsa ntchito makhadi opanda zingwe (akadali NFC yemweyo, mokulira), mafoni okhala ndi makhadi (mlongo wanga, posintha foni yake, adaumirira kuti NFC momwemo) ndi "zosavuta" zina zamoyo. paukadaulo uwu. RFID yakhala gawo lofunikira m'moyo wathu watsiku ndi tsiku: mabasi otayika, makhadi ofikira maofesi ambiri ndi nyumba zina, zikwama zazing'ono mkati mwa mabungwe (monga ) "ndi zina zotero, ndi zina zotero, ndi zina zotero."
Kwenikweni, ndichifukwa chake pali ma tag ambiri, omwe mukufuna kuti mutsegule ndikuwona zomwe zabisika mkati: chip chomwe chimayikidwa? ndi chitetezo? ndi mlongoti wanji?
Koma zinthu zoyambaβ¦
Zinali tizidutswa tating'ono ta silicon tomwe tidapanga dziko lathu momwe timadziwira lero.
Mawu ochepa okhudza kutsegula ma tag
Ndiroleni ndikukumbutseni kuti kuti mufike ku chip palokha, muyenera kutsitsa mankhwalawo pogwiritsa ntchito ma reagents amankhwala. Mwachitsanzo, chotsani chipolopolocho (kawirikawiri khadi kapena tagi ya pulasitiki yozungulira yokhala ndi mlongoti mkati), chotsani chipangizocho mosamala ku mlongoti, sambani chipangizocho kuchokera ku guluu/choteteza, nthawi zina chotsani mbali za mlongoti zomwe zagulitsidwa molimba pa zolumikizira. , ndiyeno pokhapo muwone chip ndi masanjidwe ake.
Deprocessing ndi kumverera kovuta
Zida zomwe zimagwiritsidwa ntchito poyika tchipisi zasintha kwambiri m'zaka zaposachedwa. Kumbali imodzi, izi zidakulitsa kudalirika kwa kulumikizidwa kwa chip ndikuchepetsa kuchuluka kwa zolakwika; Kumbali inayi, kungowira mu acetone kapena sulfuric acid wothira kuti musungunuke kapena kuwotcha zinthu zamoyo tsopano sikudzatsuka chip. Muyenera kukhala okhwima, sankhani chisakanizo cha ma acid kuti muchotse zigawo zosafunikira, koma nthawi yomweyo musawononge moto wamoto ku metallization ya chip.
Zovuta za deprocessing: pamene guluu kuchokera ku chip sangathe kutsukidwa pansi pazifukwa zilizonse ... ΠΠ - microscope laser, OM - microscope ya kuwala
Kapena ...
Nthawi zina, ndithudi, mumakhala ndi mwayi pang'ono ndipo chip, ngakhale ndi chosanjikiza chotchinga, chimakhala choyera, chomwe sichimakhudza kwambiri chithunzicho:
NB: Ma acid ndi zosungunulira zoyikirapo ziyenera kusungidwa pamalo abwino mpweya wabwino, kapena makamaka kunja! Osayesa izi kunyumba kukhitchini!
Mbali yothandiza
Monga ndawonera kale koyambirira kwa nkhaniyi, gawo lililonse lipereka mitundu yosiyanasiyana kapena ma tag angapo: zoyendera (zoyendera zapagulu ndi ma ski pass), otetezeka (makamaka makadi anzeru), "tsiku lililonse" ndi zina zotero.
Tiyeni tiyambe lero ndi ma tag osavuta omwe amapezeka pafupifupi kulikonse. Tiyeni tiwatchule "ma tag a tsiku ndi tsiku" chifukwa mutha kuwapeza pafupifupi kulikonse: kuchokera pa nambala ya marathon kupita kumsonkhano ndi kutumiza katundu.
Zizindikiro zomwe takambirana m'nkhaniyi zasonyezedwa mu mzere wa madontho a buluu
Ma Tag aatali a UHF
Owerenga ambiri a Habr amasewera komanso amakonda masewera. M'zaka zingapo zapitazi, pakhala pali chizolowezi chodziwika chotenga nawo gawo mumipikisano yosiyanasiyana, theka la marathon komanso ngakhale marathon. Nthawi zina chifukwa cha mendulo .
Nthawi zambiri, mwambowu usanayambike, nambala yotenga nawo mbali imaperekedwa ndi zoyika thovu pang'ono m'mbali, kumbuyo komwe - zoopsa zowopsa - chizindikiro chodziwika bwino cha RFID chimabisika. cha chochitika! Osati kwenikweni. Popeza kuyambika kwa misa kumagwiritsidwa ntchito pamipikisano yotere, ndikofunikira kuwerengera nthawi ya wophunzira aliyense kuyambira pomwe akuwoloka mzere woyambira mpaka kumapeto. Kuthamanga ndi chimango chapadera mu mawonekedwe a zipata zoyambira ndi zomaliza, wophunzira aliyense amayamba ndipo, motero, amayimitsa choyimitsa chosawoneka.
Zizindikiro zimawoneka motere:
Monga momwe zasonyezera, ngakhale ku Switzerland kuli ma tag osachepera awiri omwe amagwiritsidwa ntchito pazochitika zapagulu. Amasiyana onse mu tinyanga (mwachizoloΕ΅ezi, chopapatiza ndi chachikulu) ndi mapangidwe a chip. Zowona, muzochitika zonsezi ndi chip wamba kwambiri, wopanda chitetezo, wopanda mabelu ndi mluzu ndipo, mwachiwonekere, wopanda kukumbukira pang'ono. Ndipo, monga momwe zasonyezera, komanso kuchokera kwa wopanga uyu - .
Ndizovuta kwa ine kuweruza ngati chilichonse chalembedwa pa chip; nthawi zambiri chimangogwira ntchito kuti chizindikirike. Ngati mukudziwa zambiri, lembani mu ndemanga!
