Ndeapi Akajairwa RFID Matagi kune Yese Frequency?
Frequency inosarudza zvese zviri muRFID. Verenga chinhambwe, huwandu hwedata, kushanda kwezvakatipoteredza, mutengo payuniti imwe-zvese zvinodzokera panogara tegi pamagetsi emagetsi. Mushure mekutumira mamirioni ema tag pakutonga kwekuwana, manejimendi ezvipfuyo, uye maapplication ekubhadhara kubva 2006, mapatani akajeka.
Mabhendi matatu efrequency anotonga kutengesa kweRFID deployments: yakaderera frequency pa125-134.2 kHz, yakakwirira frequency pa13.56 MHz, uye yekupedzisira-yakakwirira frequency pakati pe860-960 MHz. Bhendi rega rega rine machipisi chaiwo akave indasitiri zviyero, uye kunzwisisa kuti ndeapi ma tag anoshanda uko kunodzivirira kudhura kutadza kuenderana.
Low Frequency
Iyo 125 kHz bhendi inomiririra yekare kushambadzira RFID tekinoroji ichiri mukugadzira inoshanda. Mhuri mbiri dzechip dzinoverengera kutumirwa kwakawanda.
EM4100 nepini yayo-inofambirana neTK4100 inoramba iri sarudzo yakagara padanho rekutanga rekuwana. Aya machipisi ekuverenga-chete anochengeta 64-bit unique identifier vachishandisa Manchester encoding, inoshanda chero kubva 100-150 kHz. Chimiro chendangariro chinotevera chimiro chakamisikidzwa: 9 misoro mabhiti, 40 mabhiti emutengi uye serial data ine mutsara parity, uye 4 column parity mabhiti ekuona kukanganisa. Hapana encryption, hapana huchokwadi-inongove nhamba kutepfenyurwa pese apo chip inopinda mundima yekuverenga.
Kuganhurwa kwe-chete kunokosha pane gap rekuchengetedza. Kuratidzira kweICT kwa2023 kwakaratidza kuumbwa kwechokwadi mumasekonzi mashanu. Zvekuvaka kupinda uko iyo yekutyisidzira modhi inotora yekutanga kudzivirira kwete chengetedzo chaiyo, EM4100/TK4100 keyfobs ichiri kufamba muhuwandu. Mitengo yakawanda inogona kusvika $0.15 payuniti.
Musiyano unonyorwa unoshandisa 512{{13}bit EEPROM yakarongwa kuita 16 mabhuroko e32 bits imwe neimwe. Inovhara 0 uye 1 inobata data yemugadziri kusanganisira 32{{15}bit UID uye chip type. Block 2 inochengeta 32-bit password yekudzivirira kuverenga/kunyora. Zvivharo 5 kusvika gumi neshanu zvinopa mushandisi nzvimbo-yakakwana kune yakapfava maapplication ayo anoda kuchengetedza zvinopfuura chiziviso chete. Kukiya mabheti anogona kushandura chero block kuti iverenge-chete modhi senge-imwe-nguva oparesheni.
Kuziva mhuka kunoita 134.2 kHz pasi peISO 11784/11785, pachishandiswa FDX-B encoding ine gumi neshanu-nyika yemadiji-yemhuka-chimiro chekodhi yenyika. Nzvimbo yekugadzira pano inobata pamusoro pe300,000 ICAR-yakasimbiswa girazi chubhu microchips gore negore kune kambani yehutano yemhuka yeTurkey chete. Biocompatible glass coating inodzivirira kurambwa kwetishu, uye machipisi anoramba achiverengwa kwehupenyu hwese hwemhuka. Kugadzirwa kwema tag nzeve kunosvika 500,000-600,000 seti pamwedzi pamapurojekiti emombe muMexico, Mongolia, Senegal, Mauritania, neBotswana.
High Frequency
Iyo 13.56 MHz bhendi inoshanda pasi pemhuri mbiri huru dzeprotocol, uye kuvavhiringidza kunokonzera matambudziko.
Chengetedzo Yambiro
ISO 14443 inovhara makadhi epedyo ane akajairwa kuverenga madaro ari pasi pe10cm. MIFARE inoramba iri iyo inotonga chip mhuri pano, asi haisi yese MIFARE yakaenzana. Mhando dzakasiyana-siyana dzinoshandisa Crypto-1 encryption dzakatyorwa kubva muna 2008-kuburitswa kwaKurume 2024 Unsaflok kwakafumura makiyi ehotera anokwana mamirioni matatu munzvimbo dzinosvika zviuru gumi nezvitatu. MIFARE DESFire neAES-128 inoramba yakachengeteka kubva pakurwiswa kunozivikanwa.
Yekutanga MIFARE Classic S50 inopa 1KB yekuchengetedza yakakamurwa kuita zvikamu gumi nematanhatu, imwe neimwe iine mabhuroko mana 16-. Chikamu chega chega chinochengeta yakazvimirira yekupinda kutonga nemakiyi maviri e6-byte (Kiyi A uye Kiyi B) uye 4-byte yekuwana mamiriro ndima. Iyo diki dhizaini inotsanangura kuverenga, kunyora, kuwedzera, uye kudzoreredza mvumo yebhuroko rega rega inobvumira granular chengetedzo kumisikidzwa-kana yakaita, isati yapunzika yekrisptographic yakaita kuti ive dzidziso.
ISO 15693
ISO 15693 inovhara makadhi enzvimbo ane madaro ekuverenga anosvika 1-1.5 metres. Iyo I · CODE 2 chip kubva kuNXP inoshanda pano iine 1024 bits yakarongeka semabhuroko makumi matatu nemaviri e4 bytes imwe neimwe. Iyo 64-bit UID yakatsva pakugadzira inovimbisa kusarudzika. Mareti ekufambisa data akarova 53 kbps, uye iyo anti-collision protocol inobata akawanda ma tag mumunda panguva imwe chete. Iyo yakareba yakaitwa I · CODE 2 yakajairwa kumaraibhurari masisitimu, zvitoro zvekutarisa cheki, uye chero application iyo iyo tag isingaunzwe zvakananga kumuverengi.
Payment & Transit
Kubhadhara uye zvikumbiro zvekufambisa zvinoda ISO 14443 kuteererwa. Iwo mamirioni maviri emakadhi etsika anotumirwa gore negore kubhengi reTajikistan anotevera chiyero ichi, achitsigira kubhadhara mutero, masevhisi ehurumende, uye zvekushandisa. Musanganisi weIsrael system anotenga mamwe mamirioni maviri makadhi gore rega evaraidzo yekubhadhara mapaki. Mashandisirwo ese ari maviri anoda kuremerwa kwekuverenga-kuzunguza kadhi kubva kure nemamita kunopa mikana yekubiridzira.
Ultra{{0}Yakakwirira Frequency
UHF RFID pakati pe860-960 MHz inoshanda pane zvakasiyana zvachose fizikisi. Panzvimbo pekubatanidza inductive, UHF inoshandisa electromagnetic backscatter, ichigonesa kuverenga kureba kwemamita gumi-gumi nemashanu nevaverengi vakagadzika uye chiziviso chebatch che200+ tags pasekondi.

Chengetedzo inotevera chimiro chemuchina wehurumende. Matagi ari OPEN state gamuchira zvakakosha mirairo. Kupa iyo chaiyo yekupinda password inofambisa tag kune SECURED state, ichigonesa kukiya uye kuvhura mashandiro. Mhando nhatu dzekiyi dziripo: dziviriro yekunyora inoda password, mvumo yekunyora zvachose isingavharwe, uye kukiya zvachose kudzivirira chero ramangwana rinonyora.
Dunhu frequency allocation inopatsanura UHF deployments. North America inoshandisa 902-928 MHz. Europe inoshanda pa865-868 MHz. Izvi zvine basa kumashandisirwo epasi rese rekutengesa uko ma tag anoyambuka miganhu.
Iyo Logistics mukana haurambike. Warehouse inventory kuverenga kwakatora mazuva nebarcode scanning yakazara mumaawa neUHF. Pallet-level tracking, identification yemota, control container-chero kwese kwese kwakakwirira-kuverengwa kwekumhanya kunopa chikonzero chekudyara kwezvivakwa.
