Ujongano lonxibelelwano lubaluleke kakhulu ekumiseni ulwazi kunye neemveliso.Iindidi zojongano lwabafundi be-RFID zahlulwe ikakhulu kujongano olunentambo kunye nojongano olungenazingcingo.Ujongano oluneengcingo ngokubanzi lunonxibelelwano olwahlukeneyo lonxibelelwano, olunje: izibuko zothotho, izibuko zenethiwekhi okanye olunye ujongano lonxibelelwano.I-Wireless interfaces ikakhulu iQhagamshela nge-WIFI, iBluetooth, njl njl. Ujongano oluhlukeneyo lunokuhlangabezana neemfuno zeemeko ezahlukeneyo zesicelo.

Uhlobo lojongano lomfundi weRFID:

1. I-Wired interfaces ibandakanya i-USB, i-RS232, i-RS485, i-Ethernet, i-TCP / IP, i-RJ45, i-WG26 / 34, ibhasi yezoshishino, enye i-interfaces yedatha eyenziwe ngokwezifiso, njl.

1) I-USB ibhekisa kwi "Universal Serial Bus", ikwabizwa ngokuba yi "Serial Line", ekumgangatho webhasi yangaphandle yokudibanisa iinkqubo zekhompyuter kunye nezixhobo zangaphandle, kwaye ikwayinkcazo yobugcisa yonxibelelwano kunye nemveliso ekunxibelelaneni nasekunxibelelaneni. ngezixhobo zangaphandle.Isetyenziswa ngokubanzi kwiimveliso zolwazi kunye nonxibelelwano ezifana neekhompyuter zobuqu kunye nezixhobo eziphathwayo, kwaye zinokudityaniswa ngokubanzi kwiimpuku, izitshixo, izishicileli, ii-scanners, iikhamera, ii-flash drives, iiselfowuni, iikhamera zedijithali, ii-hard drives, iidrive zangaphandle zangaphandle okanye iifloppy drives, amakhadi womnatha we-USB, njl.

I-2) I-RS485 ithatha ukuhanjiswa okulinganayo kunye nolwamkelo olwahlukileyo, ngoko inamandla okucinezela ukuphazamiseka kwendlela eqhelekileyo.Ukongeza, i-transceiver yebhasi inovakalelo oluphezulu kwaye inokubona amandla ombane asezantsi njenge-200mV, ngoko ke isiginali yothumelo inokubuyiselwa kumawaka eemitha kude.I-RS485 ithatha i-half-duplex mode yokusebenza, kwaye inqaku elinye kuphela likwimeko yokuthumela nangaliphi na ixesha.I-RS485 ilungele kakhulu uqhagamshelwano lwamanqaku amaninzi, olunokugcina imigca yesignali emininzi.Ukusebenzisa i-RS485 kunokuxhunywa kwinethiwekhi ukwenza inkqubo esasazwayo, evumela ukuya kuthi ga kwi-32 abaqhubi bonxibelelwano oluhambelanayo kunye nabamkeli be-32.Xa umgama wonxibelelwano kufuneka ube ngamashumi eemitha ukuya kumawaka eemitha, umgangatho webhasi ye-RS485 usetyenziswa kakhulu.

3) I-RS232 ngoku yenye yonxibelelwano oluqhelekileyo lwabafundi be-RFID.Ikakhulu iluthotho lojongano olusemgangathweni oluqulunqwe yiAmerican Electronics Industries Association EIA.I-RS sisishunqulelo se "standard enconyiweyo" ngesiNgesi, i-232 yinombolo yesazisi, i-RS232 ngummiselo weempawu zombane kunye neempawu zomzimba, isebenza kuphela kwindlela yokuhanjiswa kwedatha, kwaye ayibandakanyi indlela yokucubungula idatha.Ukusukela ukuba umgangatho wojongano lweRS232 uvele ngaphambili, kukho iintsilelo ngokwendalo.Ekubeni i-RS-232 i-transmission yesignali ephelayo enye, kukho iingxaki ezifana nengxolo eqhelekileyo yomhlaba kunye nokuphazamiseka kwemodi eqhelekileyo;kunye nomgama wothumelo mfutshane, ngokuqhelekileyo usetyenziswa ngaphakathi kwe-20m yoNxibelelwano;izinga lokuhambisa liphantsi, kwi-asynchronous transmission, izinga le-baud yi-20Kbps;ixabiso lenqanaba lomqondiso we-interface liphezulu, kwaye i-chip ye-interface yesekethe kulula ukuba yonakaliswe.

I-4) I-Ethernet isebenza kwinqanaba elisezantsi, eliyi-data link layer.I-Ethernet yinethiwekhi yendawo yendawo esetyenziswa ngokubanzi, kuquka i-Ethernet eqhelekileyo (i-10Mbit / s), i-Fast Ethernet (100Mbit / s) kunye ne-10G (10Gbit / s) i-Ethernet.Akusiyo inethiwekhi ethile, kodwa inkcazo yobugcisa.Lo mgangatho uchaza uhlobo lwentambo kunye nendlela yokucwangcisa umqondiso osetyenziswa kwinethiwekhi yendawo yendawo (LAN).I-Ethernet ihambisa iipakethi zolwazi ngesantya se-10 ukuya kwi-100 Mbps phakathi kwezixhobo ezidibeneyo.I-twisted pair cable 10BaseT Ethernet iye yaba yiteknoloji ye-Ethernet esetyenziswa ngokubanzi ngenxa yeendleko zayo eziphantsi, ukuthembeka okuphezulu kunye ne-10Mbps yesantya.

I-5) i-TCP / IP yiprotocol yokulawula ukuhanjiswa / i-intanethi ye-intanethi, eyaziwa ngokuba yi-protocol yonxibelelwano lwenethiwekhi.Yinkqubo esisiseko ye-Intanethi kunye nesiseko se-Intanethi.I-TCP / IP ichaza indlela izixhobo zombane eziqhagamshela ngayo kwi-Intanethi kunye nendlela idatha ehanjiswa ngayo phakathi kwabo.Iprothokholi ithatha i-4-layer hierarchical structure, kwaye umaleko ngamnye ubiza iprotocol enikezelwa ngumaleko wayo olandelayo ukugqiba imfuno yayo.Ngokwemigaqo ye-layman, i-TCP inoxanduva lokufumanisa iingxaki zokusasaza, ukuthumela isignali xa kukho ingxaki, kwaye ifuna ukuhanjiswa kwakhona de kube yonke idatha ikhuselekile kwaye idluliselwe ngokuchanekileyo kwindawo ekuyiwa kuyo.

I-6) I-interface ye-RJ45 idla ngokusetyenziselwa ukuhanjiswa kwedatha, kwaye isicelo esiqhelekileyo yi-interface yekhadi lenethiwekhi.I-RJ45 luhlobo lwezihlanganisi ezahlukeneyo.Kukho iindlela ezimbini zokuhlenga izixhumi ze-RJ45 ngokomgca, enye i-orange-white, i-orange, eluhlaza-emhlophe, eluhlaza okwesibhakabhaka, eluhlaza okwesibhakabhaka, eluhlaza, obomvu-omhlophe, omdaka;enye iluhlaza-mhlophe, eluhlaza, i-orenji-mhlophe, iblue, blue-white, orenji, brown-white, and brown;ngoko ke, kukho iintlobo ezimbini zemigca usebenzisa izixhumi ze-RJ45: imigca eqondileyo kunye nemigca ye-crossover.

7) Iprotocol yeWiegand ngumgangatho odibeneyo wamazwe ngamazwe kwaye iprotocol yonxibelelwano eyenziwe yi-Motorola.Isebenza kwiimpawu ezininzi zabafundi kunye neethegi ezibandakanyekayo kwiinkqubo zokulawula ukufikelela.Umgangatho we-26-bit kufuneka ube yifomathi esetyenziswa ngokuqhelekileyo, kwaye kukho kwakhona i-34-bit, i-37-bit kunye nezinye iifomati.Umgangatho we-26-bit ifomathi yifomathi evulekileyo, oku kuthetha ukuba nabani na unokuthenga ikhadi le-HID kwifomathi ethile, kwaye iintlobo zezi fomthi ezithile zivulekile kwaye zikhethwa.Ifomathi ye-26-Bit yimigangatho yoshishino esetyenziswa ngokubanzi kwaye ivulelekile kubo bonke abasebenzisi be-HID.Phantse zonke iisistim zolawulo lofikelelo zamkela ifomathi eqhelekileyo ye-26-Bit.

2. I-interface engenazintambo isetyenziselwa ukuhanjiswa kwedatha ekupheleni kwamacingo.I-interfaces eziqhelekileyo ezingenazintambo ziquka i-infrared, i-Bluetooth, i-WIFI, i-GPRS, i-3G / 4G kunye nezinye iiprothokholi ezingenazintambo.

EyahlukileyoAbafundi beRFIDxhasa iiprothokholi ezahlukeneyo kunye nokusebenza ngokuxhomekeke kusetyenziso lwazo.Unokukhetha isixhobo esifanelekileyo ngokweemfuno zeprojekthi.I-Shenzhen Handheld-Wireless Technology Co,Ltd.ibisoloko iphuhlisa ngokuzimeleyo kwaye ivelisa umfundi ophathwa ngesandla weRFID kunye nombhali ngaphezulu kweminyaka elishumi, ujongano olwahlukeneyo lunokulungiswa ukuhlangabezana neemfuno zakho zesicelo.
