Hoʻokahi-bit Tag Electronic

 

ʻO ka nui ʻikepili o ka ʻōnaehana hoʻokahi-bit hoʻokahi. Inā he ʻōnaehana hoʻokahi-bit (1b) ka hōʻailona uila, ʻelua mau mokuʻāina ka tag uila: 1 a me 0. Hiki i ka mea heluhelu/mea kākau o kēia ʻōnaehana ke hoʻopuka i ʻelua mau mokuʻāina, ʻo ia ka "tag uila i ka wahi e hana ana ka mea heluhelu/kakau" a "ʻaʻohe hōʻailona uila ma ka wahi hana o ka mea heluhelu/mea kākau." ʻO ka -bit uila ka lepili uila mua loa i hoʻohana ʻia, i ʻike mua ʻia i nā makahiki 1960. Hoʻohana nui ʻia ia ma ka ʻōnaehana Electronic Article Surveillance (EAS) ma nā hale kūʻai. Hoʻokomo pinepine ʻia ka mea heluhelu/mea kākau o kēia ʻōnaehana ma ka puka o ka hale kūʻai, a hoʻopili ʻia ka tag uila i ka mea kūʻai. Ke hele ka mea kūʻai ma ka puka hale kūʻai, hoʻomaka ka ʻōnaehana.

 

ʻAʻole pono ka -bit electronic tag i ka chip a hiki ke hana me ka hoʻohana ʻana i nā ʻano like ʻole e like me ke alapinepine radio (RF), microwave, frequency division, smart type, electromagnetic, and acousto{1}}magnetic method. Hoʻokomo ʻia ka loina hana o kahi -bit uila ma lalo nei, e lawe ana i ke ʻano RF ma ke ʻano he laʻana.

 

Ke Kumu Hana o ke Kaʻina Lekiō

 

ʻO ka ʻōnaehana hana RF he ʻekolu ʻāpana: ka mea heluhelu / mea kākau (detector), ka leka uila, a me ka deactivator. Hoʻohana ka hōʻailona uila i kahi kaapuni oscillating L-C no ka hana ʻana, a hoʻokani ke kaapuni oscillating i ke alapine i kekahi alapine resonant fR. Hoʻopuka ka ʻōnaehana hana RF heluhelu/mea kākau (detector) i kahi kahua magnetic alternate me kahi alapine fG. Ke like ka alapine o ke kahua mākēneʻe fG me ke alapine resonant fR o ka lepili uila, ʻo ke kaapuni oscillating o ka tag uila e hoʻohua i ka resonance. I ka manawa like, ʻo ke au i loko o ke kaapuni oscillating e kūʻē i ke kahua hoʻololi o waho, e alakaʻi ana i ka hōʻemi ʻana i ka amplitude o ke kahua magnetic alternating. Inā ʻike ka mea heluhelu/mea kākau (mea ʻimi) i ka hoʻemi ʻana i ke kahua mākēneki e hoʻololi ʻia, e hoʻāla ia. Ma hope o ka hoʻohana ʻia ʻana o ka leka uila, hoʻopau ʻia me ka "deactivator." Hōʻike ʻia ke kumu hana o ke ʻano RF ma ke kiʻi 5-2.

 

 

(1) Heluhelu/Kākau (Mālama).He ʻelua ʻāpana ka mea heluhelu/mea kākau (detector): kahi mea hoʻouna a me kahi mea hoʻokipa. ʻO kāna kumu kumu, ʻo ia ka hoʻohana ʻana i ka antenna hoʻouna e hoʻokuʻu i kahi kahua magnetic alternating, e hana ana i kahi wahi scanning ma waena o ka hoʻouna ʻana a me ka loaʻa ʻana o nā antennas, a e hoʻohana i ka antenna e loaʻa ai e loaʻa i kēia kahua magnetic alternating i loko o kāna mau loaʻa. Hoʻohana ka ʻōnaehana hana RF i ke kumu o ka hawewe electromagnetic resonance e ʻimi ai inā loaʻa kahi leka uila ma kahi kikoʻī. Inā ʻike ʻia kahi hōʻailona uila ma kēia wahi, hoʻāla koke ʻia kahi puʻupuʻu.

 

(2) Tag uila.ʻO ka loko o ka hōʻailona uila he L-C structured oscillating circuit, a ua hoʻokomo ʻia ka tag uila ma ka mea kūʻai ma ke ʻano kūikawā. Loaʻa nā hōʻailona uila i kēia manawa ma ka mākeke i nā hōʻailona palupalu a me nā inoa paʻakikī.

 

Hiki i ka mea ho'opau ke ho'opuka i kahi mākia mākia lawa, hiki ke ho'opau i ka capacitor ki'i'oni'oni lahilahi i loko o ka hō'ailona uila, e ho'opō'ino ai i ka hale L-C i loko o ka hō'ailona uila.

 

Hoʻololi pinepine ʻia nā deactivator e nā mea wehe a i ʻole decoders. ʻO nā Unlockers nā mea hoʻohana e hoʻopau koke i nā hōʻailona paʻakikī. ʻO nā decoder nā mea hana e hoʻopau i nā hōʻailona palupalu. Hiki i nā -decoder hoʻokaʻaʻole i hoʻohana mau ʻia ma ka mākeke i kēia mau lā ke hoʻokaʻawale i ka hōʻailona palupalu ma ke kau ʻana iā ia i loko o 20 knm ma luna o ka decoder.

 

Introduction to Electronic Article Surveillance (EAS) System

 

I kēia lā, hoʻolaha nui ʻia ka noi ʻana o ka ʻōnaehana Electronic Article Surveillance (EAS) i ka ʻoihana kūʻai. He huahana uila -ʻaihue ia e hōʻemi ana i ka ʻaihue mea kūʻai i ka wā -kūʻai wehe ʻia, ma laila e hoʻonui ai i ka loaʻa kālā, a ʻo ia kekahi o nā mea palekana i hāpai nui ʻia e ka ʻoihana kūʻai nui -nui. ʻO ka ʻoiaʻiʻo, ʻo ka ʻōnaehana EAS kahi ʻōnaehana hōʻike leka uila maʻalahi. No ka mea ʻelua wale nō mau mokuʻāina, hiki iā ia ke hōʻike i ke alo a i ʻole ka ʻole o ka mea kūʻai aku, ʻaʻole ke ʻano o ka mea kūʻai. ʻO nā ʻanuʻu no ka ʻike ʻaihue ʻōnaehana EAS penei.

 

(1) Hoʻopili ʻia ka -tag anti ʻaihue i ka mea kūʻai.

(2) Hoʻokomo ʻia nā mea ʻike ma ka puka puka hale kūʻai a i ʻole ke ala kālā.

(3) Ma hope o ka uku ʻana, hele ka mea kūʻai i loko o kahi decoder i hoʻolaʻa ʻia no ka hoʻopau ʻana i ka hōʻailona a i ʻole hoʻohana i kahi laka wehe -e wehe i ka hōʻailona.

(4) Ke hele aku nā mea kūʻai i uku ʻole ʻia (me ka lepe i hoʻopili ʻia) ma ka puka, ʻike ka mea ʻike puka i ka hōʻailona a hoʻopuka i kahi puʻupuʻu, e keakea ana i nā mea kūʻai mai ka haʻalele ʻana.

 

Hoʻokaʻawale ʻia nā lepili uila i nā inoa palupalu a me nā inoa paʻakikī. He haʻahaʻa ke kumu kūʻai o nā hōʻailona palupalu a pili pono i nā mea kūʻai "paʻakikī". ʻAʻole hiki ke hoʻohana hou ʻia nā hōʻailona palupalu. ʻOi aku ka nui o ka -uku paʻa ma mua o nā hōʻailona palupalu akā hiki ke hoʻohana hou ʻia. Pono e hoʻolako ʻia nā hōʻailona paʻa me kahi detacher kūikawā a hoʻohana nui ʻia no nā mea palupalu a maʻalahi e komo e like me nā lole.

 

ʻO ka hapa nui o nā decoders he -contact device me kekahi kiʻekiʻe decoding. Ke nānā ka cashier a ʻeke paha i nā mea, hiki ke hoʻokaʻawale ʻia ka leka uila me ka ʻole e hoʻopā i ka wahi degaussing. Inā haʻalele ka mea kūʻai i ka hale kūʻai me ka wehe ʻole ʻia, e hoʻāla ka mea ʻike i kahi alarm, e hoʻomanaʻo ana i ka mea kūʻai kālā, ka mea kūʻai aku, a me nā limahana palekana o ka hale kūʻai e lawelawe koke iā ia.

 

ʻAʻole hiki i ka ʻōnaehana Electronic Article Surveillance (EAS) ke hōʻoluʻolu ʻole i nā mea kūʻai aku e like me nā ʻōnaehana kiaʻi a lawelawe pū kekahi ma ke ʻano he mea pale. ʻEhā mau ʻenehana nui i loko o ka ʻōnaehana EAS: ʻenehana lekiō, electromagnetic, microwave, a me acousto{1}} ʻenehana. ʻO ka mea maʻamau, ʻoi aku ka liʻiliʻi o nā huahana electromagnetic a me RF, a paʻa mau ko lākou mau hōʻailona i ka mea kūʻai a i ʻole ka hōʻailona, ​​ʻoiai ʻoi aku ke kumukūʻai o ka microwave a me ka acousto{3}}magnetic tag.
