Amazinga okuxhumana omaka befrikhwensi yomsakazo ayisisekelo sokuklanywa kwe-tag chip.Izindinganiso zamanje zokuxhumana zamazwe ngamazwe ezihlobene ne-RFID ikakhulukazi zihlanganisa i-ISO/IEC 18000 standard, ISO11784/ISO11785 standard protocol, ISO/IEC 14443 standard, ISO/IEC 15693 standard, EPC standard, njll.

1. I-ISO/TEC 18000 isuselwe ezingeni lamazwe ngamazwe lokuhlonza ifrikhwensi yomsakazo futhi ingahlukaniswa kakhulu ngalezi zingxenye ezilandelayo:

1).I-ISO 18000-1, amapharamitha ajwayelekile okuxhumana komoya, alinganisa ithebula lepharamitha yokuxhumana kanye nemithetho eyisisekelo yamalungelo empahla yengqondo evame ukubonwa kuphrothokholi yokuxhumana yesixhumi somoya.Ngale ndlela, amazinga ahambisana nebhendi ngayinye yefrikhwensi awadingi ukusho ngokuphindaphindiwe okuqukethwe okufanayo.

2).I-ISO 18000-2, amapharamitha wesixhumi esibonakalayo somoya angaphansi kwefrikhwensi engu-135KHz, ecacisa ukusebenzelana okubonakalayo kokuxhumana phakathi komaki nabafundi.Umfundi kufanele abe nekhono lokuxhumana namathegi ohlobo+A (FDX) kanye nohlobo+B (HDX);icacisa izimiso nemiyalelo kanye nezindlela zokulwa nokushayisana zokuxhumana kwamathegi amaningi.

3).I-ISO 18000-3, imingcele yokusebenzelana komoya ku-13.56MHz imvamisa, ecacisa ukusebenzelana komzimba, izivumelwano nemiyalo phakathi komfundi nomaka kanye nezindlela zokulwa nokushayisana.Iphrothokholi yokunqanda ukushayisana ingahlukaniswa ibe izindlela ezimbili, futhi imodi 1 ihlukaniswe yaba uhlobo oluyisisekelo namaphrothokholi amabili anwetshiwe .I-Mode 2 isebenzisa iphrothokholi ye-FTDMA ye-time-frequency multiplexing, enenani lamashaneli angu-8, afanele izimo lapho inani lamathegi likhulu.

4).I-ISO 18000-4, amapharamitha esixhumi esibonakalayo somoya kumafrikhwensi angu-2.45GHz, imingcele yokuxhumana yokusebenzelana komoya engu-2.45GHz, ecacisa ukusebenzelana okubonakalayo, amaphrothokholi nemiyalo phakathi komfundi nomaka kanye nezindlela zokulwa nokushayisana.Izinga lihlanganisa izindlela ezimbili.Imodi 1 umaka wokungenzi lutho osebenza ngendlela yomfundi-umbhali-kuqala;I-Mode 2 iyithegi esebenzayo esebenza ngendlela yokumaka kuqala.

5).I-ISO 18000-6, imingcele yokusebenzelana komoya ku-860-960MHz imvamisa: Icacisa ukusebenzelana komzimba, izivumelwano nemiyalo phakathi komfundi nomaka kanye nezindlela zokulwa nokushayisana.Iqukethe izinhlobo ezintathu ze-passive tag interface protocols: I-TypeA, i-TypeB ne-TypeC.Ibanga lokuxhumana lingafinyelela ngaphezu kwe-10m.Phakathi kwazo, i-TypeC yabhalwa yi-EPCglobal futhi yavunywa ngoJulayi 2006. Inezinzuzo ngesivinini sokuqashelwa, isivinini sokufunda, isivinini sokubhala, umthamo wedatha, ukulwa nokushayisana, ukuphepha kolwazi, ukuguquguquka kwebhendi, ukulwa nokuphazamiseka, njll., futhi iyona esetshenziswa kabanzi.Ngaphezu kwalokho, izinhlelo zokusebenza zamanje zebhendi yefrikhwensi yomsakazo zigxile ku-902-928mhz, kanye no-865-868mhz.

6).I-ISO 18000-7, amapharamitha okusebenza komoya ku-433MHz imvamisa, amapharamitha okuxhumana okusebenza komoya angu-433+MHz, acacisa ukusebenzelana komzimba, izivumelwano nemiyalo phakathi komfundi nomaka kanye nezindlela zokulwa nokushayisana.Omaka abasebenzayo banebanga lokufunda elibanzi futhi bafanele ukulandelela izimpahla ezinkulu ezingashintshi.

2. ISO11784, ISO11785 umthetho olandelwayo ojwayelekile: Ububanzi befrikhwensi yebhendi ephansi yokusebenza ngu-30kHz ~ 300kHz.Imvamisa yokusebenza ejwayelekile yilezi: 125KHz, 133KHz, 134.2khz.Ibanga lokuxhumana lamathegi efrikhwensi ephansi ngokuvamile lingaphansi kwemitha elingu-1.
I-ISO 11784 kanye ne-ISO11785 ngokulandelanayo icacisa ukwakheka kwekhodi nemihlahlandlela yobuchwepheshe yokuhlonza izilwane.Izinga asisicacisi isitayela nosayizi we-transponder, ngakho-ke ingaklanywa ngezindlela ezihlukahlukene ezifanele izilwane ezihilelekile, njengamashubhu engilazi, ama-ear tag noma amakholomu.linda.

3. I-ISO 14443: Izinga le-ISO14443 lamazwe ngamazwe lichaza izixhumanisi zesignali ezimbili: I-TypeA ne-TypeB.I-ISO14443A ne-B azihambelani.
I-ISO14443A: Ivamise ukusetshenziselwa amakhadi okulawula ukufinyelela, amakhadi ebhasi kanye namakhadi amancane agcinwe inani eligciniwe, njll., futhi inesabelo semakethe esiphezulu.
I-ISO14443B: Ngenxa ye-coefficient ephezulu yokubethela, ifaneleka kakhulu amakhadi e-CPU futhi ivame ukusetshenziselwa amakhadi omazisi, amaphasipoti, amakhadi e-UnionPay, njll.

4. ISO 15693: Lena iphrothokholi yokuxhumana ngaphandle kokuthinta ebangeni elide.Uma kuqhathaniswa ne-ISO 14443, ibanga lokufunda likude.Isetshenziswa kakhulu ezimeni lapho inani elikhulu lamalebula lidinga ukukhonjwa ngokushesha, njengokuphathwa kwempahla, ukulandelela izinto, njll. I-ISO 15693 inezinga lokuxhumana elisheshayo, kodwa amandla ayo okulwa nokushayisana abuthakathaka kune-ISO 14443.
