Chisinthiko cha rfid

DZINA LONSE LA RFID ndi chidziwitso cha radiory. Uwu ndi ukadaulo wopanda zingwe komanso mtundu waukadaulo wozindikira zokha. Dongosolo la RFID ndi chipangizo cha hardware kutengera ukadaulo wa RFID, zomwe zimagwiritsa ntchito wailesi ya waya wopanda waya pa non {{}} funsani kulumikizana kwa data. Imagwiritsa ntchito wailesi ya waya yopanda zingwe kuti muwerenge ndikulemba kujambula Amawerengedwa kuti ndi amodzi mwamisirimo omwe amalonjeza kwambiri m'zaka za m'ma 2000 zino.

 

Mu 1935, bwana Robert Watson Watt adapanga wayilesi ndi kutulutsa (rading), omwe angawaganiziridwe kuti chiyambi cha rfid. Tekinoloje yapanoloji yomwe ilipo kale kuyambira 1940 mpaka 1950 ndipo idayamba kugwiritsidwa ntchito koyamba pa Nkhondo Yadziko II. Teminoyi idagwiritsidwa ntchito ndi allies ndi Germany kuti azindikire mdani komanso ndege zochezeka. Charles Walton adapanga RFID "yonyamula RFID Mtengo wokwera wa RFID woyambirira umalepheretsa kugwiritsa ntchito malonda. Ndi chitukuko cha ukadaulo, mtengo wa Hardware unachepa, ndipo sizinathe mpaka 1980 kuti zidayamba kubisidwa. Pambuyo pazaka zambiri zosintha mosalekeza, monga kafukufuku wochepetsa RFFID, kuti ukadaulo uja ukupitilirabe kusintha. Hardware amachepetsa ndalama. Mu 2003, United States idalengeza za muyezo woyamba wa wailesi

 

Mfundo yogwira ntchito ya RFID

Choyamba, tiyenera kudziwa kuti dongosolo lathunthu la RFID lili ndi magawo atatu: wowerenga, chizindikiro chamagetsi, ndi dongosolo la data. Mfundo yake yogwira ntchito ndikuti chimbudzi chimalowa m'malo mwa owerenga, ndipo owerenga amatulutsa pafupipafupi mphamvu ya wayilesi, yomwe imagwiritsidwa ntchito ndi dera loyendetsa la tag kuti atumize deta yamkati. Pakadali pano, owerenga amalandira motsatizana ndi kumasulira deta, ndikuwatumiza ku pulogalamu yogwirira ntchito.

 

Ngati RFID imawerengedwa molingana ndi njira yoperekera magetsi, imatha kugawidwa mu RFID yogwira, rfid, ndi semi yogwira rfid.

1.

Pakati pa mitundu iyi ya rfid, rfive rfid ali ndi mawonekedwe oyamba komanso okhwima, ndipo ntchito yake ndi yotalikirapo kwambiri. Amatha kunenedwa kuti ndi njira yomangira chabe. RFID PRFID ilibe gwero lamphamvu, kodi angapereke bwanji mphamvu? M'malo mwake, ndikulandila zizindikiro za Microwave zotchulidwa ndi owerenga owerenga a RFID ndikupeza mphamvu kudzera mu coils yoyatsira electromagnetic touction tokha, motero kumaliza kusintha kwa chidziwitso. Kuphatikiza apo, ntchito yake pafupipafupi imakhala pa 125khz, 13.53mhz, ndi zina zambiri, ndipo nthawi zambiri timagwiritsa ntchito khadi ya a Nateler, ndi khadi lazakudya.

RFID imatha kunenedwa kuti ikhale yogwira ntchito yogwira, yomwe siyinali yotchuka kwa nthawi yayitali poyerekeza ndi rfid. Komabe, zakhalapo m'moyo wathu watsiku ndi tsiku, monga njira yamagetsi yosungirako magetsi (ndi zina) pamaulendo akulu. Monga momwe dzinalo likusonyezera, RFID yogwira ntchito imafunikira mphamvu zakunja ndipo zimatumiza mosadukiza kuti owerenga a RFID. Kukula kwake ndi kwakukulu, komanso amakhalanso ndi kutalika kwakutali komanso kuthamanga kwapamwamba, ena omwe amatha kufikira 100 metres. Kuchuluka kwa RFID kumakhala kofanana kwambiri kwa 900mhz, 2.45ghz, 5.85ghz, 5.8Hgzz, etc

 

3.. Semi yogwira rfid

Chifukwa cha maubwino ndi zovuta za rfid zonse ziwiri ndi zotakataka, zongopeka, zimakhala ndi mtunda waufupi. Ngakhale RFID yogwira imakhala ndi mtunda wautali, zimafunikira mphamvu yakunja ndipo ili ndi buku lalikulu. Chifukwa cha kufunikira kwa msika, semu iyi {} Sizigwira ntchito ndipo sizitumiza zizindikiro. Imangopangidwa kokha pomwe tag imalowa pansi pa oyendetsa {{5}
