Background & Application
RFID tekinoroji tekinoroji yekuzivikanwa tekinoroji yakavakirwa pane isina waya masaini uye inokodzera akasiyana siyana ekushandisa. Iyo iri kugamuchira yakawedzera kutariswa mumaraibhurari, zvinyorwa uye archive manejimendi. Nekuwedzera zvinyorwa zveRFID kumabhuku, zvinyorwa uye zvakachengetwa, mabasa akadai sekuverenga otomatiki, kubvunza, kudzoreredza uye kudzoka kunogona kuitika, kuvandudza manejimendi kunyatsoshanda uye sevhisi nhanho yezvinyorwa zvemabhuku.
Kune marudzi maviri makuru eRFID mavara anoshandiswa mumaraibhurari uye archive gwaro manejimendi, RFID HF mavara uye RFID UHF mavara. Aya mavara maviri ane maitiro akasiyana. Rega ndiongorore kusiyana kwavo pazasi:
RFID tekinoroji inogona kukamurwa kuita akati wandei marudzi zvichienderana neakasiyana ma frequency ekushanda: yakaderera frequency (LF), yakakwira frequency (HF), Ultra yakakwira frequency (UHF) uye microwave (MW). Pakati pavo, yakakwira frequency uye yekupedzisira-yakakwirira frequency ndiwo maviri anonyanya kushandiswa RFID matekinoroji parizvino. Mumwe nemumwe ane zvazvakanakira uye zvinogumira, uye ane akasiyana mashandiro mumamiriro akasiyana.
Kushanda musimboti: Yakakwira-frequency RFID tekinoroji inoshandisa musimboti wepedyo-munda inductive coupling, kureva kuti, muverengi anotumira simba uye anotsinhana data netag kuburikidza nemagineti. UHF RFID tekinoroji inoshandisa musimboti wekure-munda electromagnetic radiation, kureva kuti, muverengi anotumira simba uye anotsinhana data netag kuburikidza nemagetsi mafungu.
Kuongorora kusarudzwa kwechigadzirwa
1. Chipisi:HF inokurudzira kushandisa NXP ICODE SLIX chip, iyo inowirirana nemitemo ISO15693 uye ISO/IEC 18000-3 Mode 1. Iine EPC yakakura yekuyeuka ye1024 bits, inogona kunyora zvakare data 100,000 nguva, uye inogona kuchengetedza data kwemakore anopfuura 10.
UHF inokurudzira kushandisa NXP UCODE 8, Alien Higgs 4, inoenderana nemitemo ISO 18000-6C uye EPC C1 Gen2, EPC, 128 bit mushandisi memory, inogona kunyora zvakare data ka100,000, uye iyo data inogona kuchengetwa kweanopfuura gumi. makore.
2. Antennas: HF antennas dzakatetepa, izvo zvinodzikisira kukanganisa kweakawanda-tag stacking. Electromagnetic waves anogona kuendesa rimwe simba kune ma tag ari kumashure kwavo kuburikidza neantenna. Iwo akanyanya-kutetepa muchitarisiko, akaderera mumutengo, akanakisa mukuita, uye zvakanyanya kuvanzwa. Naizvozvo, mavara eHF akakodzera manejimendi emabhuku uye mabhokisi ekuchengetedza. Nekudaro, mune imwechete-peji faira manejimendi, inonyanya kushandiswa kune zvakanyanya zvakavanzika mafaera, senge zvinyorwa-zvakavanzika zvepamusoro, akakosha evashandi mafaira, madhizaini edhizaini, uye zvakavanzika zvinyorwa. Pane chete kana mapeji mashoma mumapotfolio aya. Kushandisa HF tag kunopindirana zvakanyanya, zvichikonzera kupindirana, kukanganisa kurongeka kwekuzivikanwa, uye kutadza kuzadzisa zvinodiwa manejimendi. Mune ino kesi, zvinokurudzirwa kushandisa iyo UHF yekuisa mazita mhinduro.
3. Pamusoro zvinhu: Ose ari maviri HF neUHF anogona kushandisa bepa reunyanzvi sechinhu chepamusoro, uye anogona kudhinda akagadziridzwa zvinyorwa, mapatani kana mabhakodhi. Kana iwe usingade kudhinda, unogona kushandisa wet inlay zvakananga.
4. Glue: Mamiriro ekushandiswa kwema tag anowanzo kunamatira pabepa. Zviri nyore kunamatira uye nharaunda yekushandisa haina hutsinye. Yakaderera-inodhura inopisa inonyungudutsa adhesive kana mvura glue inogona kushandiswa kazhinji.
5. Bepa rekuburitsa:Kazhinji, pepa rinotsigirwa negirazi rine silicone mafuta layer rinoshandiswa, iro risinganamate uye rinoita kuti zvive nyore kubvarura tag.
6. Kuverengera: HF RFID tekinoroji ndeyepedyo-munda inductive coupling tekinoroji, uye mashandiro ayo idiki, kazhinji mukati megumi masendimita. UHF RFID tekinoroji ndeyekure-munda electromagnetic radiation tekinoroji. Iyo electromagnetic wave ine imwe dhigirii yekupinda uye yekushanda kwayo yakakura, kazhinji inodarika 1 mita. Chinhambwe chekuverenga cheHF idiki, saka inokwanisa kuwana nemazvo mabhuku kana mafaera ekuchengetedza.
7. Kukurumidza kuverenga: Nekuda kwekudzivirirwa kwepedyo-munda inductive coupling musimboti, HF RFID tekinoroji ine inononoka kuverenga kumhanya uye zvakaoma kuverenga akawanda ma tag panguva imwe chete. Nekuda kwemabhenefiti eiyo kure-munda electromagnetic radiation musimboti, UHF RFID tekinoroji ine kukurumidza kuverenga kumhanya uye neboka kuverenga basa. UHF tekinoroji ine chinhambwe chekuverenga uye nekukurumidza kuverenga nekukurumidza, saka ichave inoshanda zvakanyanya pakuverenga mabhuku kana mafaera.
8. Anti-kupindira kugona: Iyo yepedyo-munda inductive coupling yeyakakwira-frequency RFID tekinoroji inoderedza kungangoita waya isina kupindira, ichiita yakakwira-frequency tekinoroji yakanyanya "kudzivirira" kune ruzha rwezvakatipoteredza uye kupindira kwemagetsi (EMI), saka ine yakasimba anti-kukanganisa kugona. . UHF inoshandisa musimboti we electromagnetic emission, saka inobatwa zvakanyanya nekukanganiswa kwemagetsi. Panguva imwecheteyo, simbi icharatidza zviratidzo uye mvura inogona kutora zviratidzo. Izvi zvinhu zvinokanganisa basa rakajairwa reiyo label Kunyangwe zvimwe zvimiti zveUHF mushure mekuvandudzwa kwetekinoroji zvine mashandiro akanaka mukudzivirira kukanganiswa kubva kusimbi uye zvinwiwa, zvichienzaniswa neakakwira-frequency label, UHF ichiri yakaderera zvishoma, uye dzimwe nzira dzinoda kushandiswa gadzirisa.
9. Kushandiswa kwemavara eRFID pamwe chete nematanho akafanana negonhi uye masisitimu anogona kudzivirira zvinobudirira mabhuku nemafaira kubva pakurasika uye kuita mabasa earamu ekubvisa zvisiri pamutemo.
HF neUHF RFID mhinduro imwe neimwe ine zvayakanakira nezvayakaipira, uye kusarudzwa kunofanirwa kuyerwa nekuenzaniswa zvichienderana nezvinodiwa uye mamiriro.
