Sadarwar sadarwa tana da mahimmanci musamman don docking na bayanai da samfura.Nau'in mu'amala na masu karanta RFID an raba su zuwa hanyoyin sadarwa na waya da musaya mara waya.Hanyoyin sadarwa na waya gabaɗaya suna da nau'ikan mu'amalar sadarwa iri-iri, kamar: tashoshin jiragen ruwa, tashoshin sadarwa ko sauran hanyoyin sadarwa.Hanyoyin sadarwa mara waya sun fi Haɗa tare da WIFI, Bluetooth, da dai sauransu. Hanyoyi daban-daban na iya biyan buƙatun yanayin aikace-aikacen daban-daban.

Nau'in mai karanta RFID:

1. Wired musaya hada da USB, RS232, RS485, Ethernet, TCP/IP, RJ45, WG26/34, masana'antu bas, sauran musamman data musaya, da dai sauransu.

1) USB yana nufin "Universal Serial Bus", kuma ana kiranta da "Serial Line", wanda shine ma'auni na bas na waje don haɗa tsarin kwamfuta da na'urori na waje, kuma shi ne ƙayyadaddun fasaha don shigarwa da abubuwan fitarwa a cikin haɗi da sadarwa. tare da kayan aiki na waje.Ana amfani da shi sosai a cikin bayanai da samfuran sadarwa kamar kwamfutoci na sirri da na'urorin hannu, kuma ana iya haɗa shi da yawa zuwa beraye, maɓallan madannai, na'urorin bugu, na'urar daukar hoto, na'urorin daukar hoto, kyamarori, filasha, wayoyin hannu, kyamarori na dijital, rumbun kwamfyuta ta hannu, na'urorin gani na waje ko floppy drives, USB network cards, da dai sauransu.

2) RS485 yana ɗaukar daidaitaccen watsawa da liyafar banbance, don haka yana da ikon murkushe tsangwama-yanayin gama gari.Bugu da ƙari, mai ɗaukar bas yana da babban hankali kuma yana iya gano ƙarfin lantarki mai ƙarancin 200mV, don haka ana iya dawo da siginar watsawa dubban mita nesa.RS485 yana ɗaukar yanayin aiki na rabin duplex, kuma maki ɗaya kawai yana cikin yanayin aikawa a kowane lokaci.RS485 ya dace sosai don haɗin kai mai ma'ana da yawa, wanda zai iya adana layukan sigina da yawa.Aiwatar da RS485 za a iya haɗa shi don samar da tsarin da aka rarraba, wanda ke ba da damar har zuwa 32 masu haɗin haɗin kai da masu karɓa 32.Lokacin da ake buƙatar nisan sadarwa ya zama dubun mita zuwa dubunnan mita, ana amfani da mizanin serial bas na RS485.

3) RS232 a halin yanzu ɗayan hanyoyin sadarwa ne na gama gari don masu karanta RFID.Yana da ma'auni na mu'amala na zahiri na musamman wanda Ƙungiyar Masana'antun Lantarki ta Amurka EIA ta tsara.RS shine taƙaitaccen "ma'auni mai ba da shawara" a cikin Ingilishi, 232 shine lambar ganewa, RS232 shine ka'idojin halayen lantarki da halayen jiki, yana aiki ne kawai akan hanyar watsa bayanai, kuma baya haɗa da hanyar sarrafa bayanai.Tun da ma'aunin mu'amala na RS232 ya bayyana a baya, akwai kasawa ta halitta.Tun da RS-232 sigina ce mai ƙarewa guda ɗaya, akwai matsaloli kamar surutun ƙasa na gama gari da tsangwama na yanayin gama gari;kuma nisan watsawa gajere ne, gabaɗaya ana amfani da shi a cikin Sadarwar 20m;Yawan watsawa yana da ƙasa, a cikin watsawar asynchronous, ƙimar baud shine 20Kbps;ƙimar matakin sigina na ƙirar yana da girma, kuma guntu na da'irar dubawa yana da sauƙin lalacewa.

4) Ethernet yana aiki a ƙasan Layer, wanda shine Layer link Layer.Ethernet cibiyar sadarwar yanki ce da ake amfani da ita sosai, gami da daidaitaccen Ethernet (10Mbit/s), Fast Ethernet (100Mbit/s) da 10G (10Gbit/s) Ethernet.Ba takamaiman hanyar sadarwa bane, amma ƙayyadaddun fasaha.Wannan ma'auni yana bayyana nau'in kebul da hanyar sarrafa siginar da ake amfani da shi a cibiyar sadarwar yanki (LAN).Ethernet yana watsa fakitin bayanai akan ƙimar 10 zuwa 100 Mbps tsakanin na'urori masu haɗin kai.Twisted biyu na USB 10BaseT Ethernet ya zama fasahar Ethernet da ake amfani da ita sosai saboda ƙarancin farashi, babban abin dogaro da saurin 10Mbps.

5) TCP/IP shine ka'idar sarrafa watsawa/ka'idar haɗin kai ta Intanet, wanda kuma aka sani da ka'idar sadarwa ta hanyar sadarwa.Ita ce ainihin ka'idar Intanet kuma tushen Intanet.TCP/IP yana bayyana yadda na'urorin lantarki ke haɗawa da Intanet da kuma yadda ake watsa bayanai tsakanin su.Yarjejeniyar tana ɗaukar tsari mai nau'i 4-Layer, kuma kowane Layer yana kiran ƙa'idar da Layer na gaba ya samar don kammala bukatunsa.A cikin sharuddan layman, TCP ne ke da alhakin gano matsalolin watsawa, aika sigina lokacin da akwai matsala, da kuma buƙatar sake aikawa har sai an aika duk bayanai cikin aminci kuma daidai da aika zuwa wurin da aka nufa.

6) Yawanci ana amfani da ƙirar RJ45 don watsa bayanai, kuma mafi yawan aikace-aikacen da aka fi sani shine ƙirar katin sadarwar.RJ45 nau'in masu haɗawa ne daban-daban.Akwai hanyoyi guda biyu don warware masu haɗin RJ45 bisa ga layin, ɗayan orange-fari, orange, kore-fari, blue, blue-fari, kore, launin ruwan kasa-fari, launin ruwan kasa;ɗayan kuma kore-fari, kore, lemu-fari, shuɗi, shuɗi-fari, lemu, ruwan kasa-fari, da ruwan kasa;saboda haka, akwai nau'ikan layukan guda biyu ta amfani da masu haɗin RJ45: madaidaiciya-ta hanyar layi da layin giciye.

7) Ka'idar Wiegand wata ƙa'idar haɗin kai ce ta duniya kuma ƙa'idar sadarwa ce ta Motorola ta haɓaka.Ya shafi halaye da yawa na masu karatu da alamun da ke cikin tsarin sarrafa damar shiga.Daidaitaccen 26-bit ya kamata ya zama tsarin da aka saba amfani da shi, kuma akwai kuma 34-bit, 37-bit da sauran tsarin.Daidaitaccen tsarin 26-bit shine buɗaɗɗen tsari, wanda ke nufin cewa kowa zai iya siyan katin HID a takamaiman tsari, kuma nau'ikan waɗannan takamaiman nau'ikan suna buɗe kuma zaɓi ne.Tsarin 26-Bit tsarin masana'antu ne da ake amfani da shi sosai kuma yana buɗe wa duk masu amfani da HID.Kusan duk tsarin sarrafa damar shiga suna karɓar daidaitaccen tsarin 26-Bit.

2. Wireless interface an fi amfani dashi don watsa bayanai a ƙarshen mara waya.Hanyoyin mu'amala mara waya ta gama gari sun haɗa da infrared, Bluetooth, WIFI, GPRS, 3G/4G da sauran ka'idoji mara waya.

Daban-dabanRFID masu karatugoyi bayan ka'idoji daban-daban da wasan kwaikwayo dangane da amfanin su.Kuna iya zaɓar na'urar da ta dace daidai da bukatun aikin.Shenzhen Handheld-Wireless Technology Co, Ltd.ya kasance yana haɓakawa da samar da mai karantawa da marubuci na RFID sama da shekaru goma, ana iya keɓance musaya daban-daban don biyan bukatun aikace-aikacenku.
