Electronic Tag pakhat-bit a ni

 

One-bit system a data volume chu bit khat a ni. Electronic tag chu one-bit (1b) system a nih chuan electronic tag hian state pahnih chauh a nei a, chungte chu 1 leh 0. He system-a reader/writer hian state pahnih chauh a output thei a, chungte chu "reader/writer hnathawhna hmuna electronic tag" leh "reader/writer hnathawhna hmuna electronic tag awm lo" te an ni. One-bit electronic tag hi sumdawnna atana hman hmasak ber electronic tag a ni a, kum 1960 chho vela lo lang hmasa ber a ni. Store-a Electronic Article Surveillance (EAS) system-ah hman a ni ber. He system chhiartu/ziaktu hi dawr kawtah dah a ni tlangpui a, electronic tag chu thil zawrh chungah dah a ni. Store luhna atanga thil zawrh a kal chuan system chu a alarm ta a ni.

 

One-bit electronic tag hian chip a mamawh lo va, radio frequency (RF), microwave, frequency division, smart type, electromagnetic, leh acousto{1}}magnetic method hrang hrang hmangin hna a thawk thei a ni. One-bit electronic tag hnathawh dan tur chu a hnuaia mi ang hian tarlan a ni a, RF method chu entirnan kan hmang a ni.

 

Radio Frequency Method hmanga hnathawh dan tur

 

RF working system hi hmun thum a awm a, chungte chu reader/writer (detector), electronic tag leh deactivator te an ni. Electronic tag hian hnathawh nan L-C oscillating circuit a hmang a, oscillating circuit hian frequency chu resonant frequency fR engemaw zatah a tune a ni. RF working system reader/writer (detector) hian frequency fG engemaw zat nei magnetic field danglam tak a pe chhuak thin. Alternating magnetic field fG frequency chu electronic tag-a resonant frequency fR nen a inang chuan electronic tag-a oscillating circuit chuan resonance a siam chhuak thin. Chutih rual chuan oscillating circuit-a current chuan pawn lam alternating magnetic field chu a dodal a, chu chuan alternating magnetic field amplitude a tihhniam phah a ni. Reader/writer (detector) chuan alternating magnetic field a tlahniam tih a hriat chuan a alarm ang. Electronic tag hman a nih hnuah "deactivator" hmangin tihchhiat a ni. RF method hnathawh dan tur chu Figure 5-2-ah hian tarlan a ni.

 

 

(1) Chhiartu/ziaktu (Detector).Reader/writer (detector) hi a tlangpuiin hmun hnih a awm a, chungte chu transmitter leh receiver te an ni. A thu bulpui ber chu transmitting antenna hmanga alternating magnetic field emit a, transmitting leh receiving antenna inkara scanning area siam a, receiving antenna hmanga he alternating magnetic field hi a receiving range chhunga dawng tur a ni. RF working system hian electromagnetic wave resonance principle hmangin electronic tag chu range bik pakhatah a awm leh awm loh zawn nan a hmang a ni. He hmunah hian electronic tag a lo lang a nih chuan alarm a ri nghal vek a ni.

 

(2) Electronic Tag hmanga siam a ni.Electronic tag chhung lam hi L-C structured oscillating circuit a ni a, electronic tag hi thil zawrh chungah hian a bik takin dah a ni. Tuna market-a electronic tag awm mek zingah hian soft tag leh hard tag te pawh a tel.

 

Deactivator hian magnetic field tling tak a siam thei a, chu chuan electronic tag chhunga thin-film capacitor chu a tichhia thei a, electronic tag chhunga L-C structure chu a tichhia thei a ni.

 

Deactivator te hi unlocker emaw decoder emaw hmanga thlak a ni fo thin. Unlocker hi hard tag hrang hrang rang taka paih chhuahna hmanrua a ni. Decoder hi soft tags disable thei device a ni. Tunlai market-a hman tlanglawn tak non-contact decoder te hian soft tag chu decoder atanga cm 20 chhunga pass mai maiin an decode thei a ni.

 

Electronic Article Surveillance (EAS) System chungchang hriattirna

 

Tunah chuan retail business-ah Electronic Article Surveillance (EAS) system hman a ni nasa hle a. Electronic anti-theft product a ni a, open-shelf sales laiin merchandise theft a tihtlem a, chu chuan sales profit a tipung a, tuna large-scale retail industry-in security measures an hman nasa ber zinga mi a ni. Dik tak chuan EAS system hi radio frequency hriat theihna system awlsam tak a ni. State pahnih chauh a neih avangin thil zawrh awm leh awm loh chauh a tarlang thei a, thil zawrh chu eng nge a nih tih a tilang thei lo. EAS system rukbo hmuhchhuah dan tur chu hetiang hi a ni.

 

(1) Anti-theft tag chu thil zawrh chungah a inbun a.

(2) Store chhuahna kawngkhar emaw, cashier kawngkhar emaw-ah detector dah a ni.

(3) Pawisa pek zawhah chuan merchandise chu dedicated decoder kaltlangin tag chu a disable emaw, un-locker hmangin tag chu a paih chhuak emaw a ni.

(4) Pawisa pek loh thil (attached tag nen) chu chhuahna atanga a kal chuan, kawngkhar detector chuan tag chu a hmuchhuak a, alarm a tichhuak a, chu chuan thil chu a chhuah loh nan a titawp a ni.

 

Electronic tag hi soft tag leh hard tag ah then a ni. Soft tag hi a man a tlawm zawk a, "harder" merchandise-ah direct-in a inzawm a ni. Soft tag hi hman nawn theih a ni lo. Hard tag hian soft tag aiin one{3}}time cost a sang zawk a mahse hman nawn theih a ni. Hard tag-ah hian specialized detacher dah tur a ni a, a tam zawk chu thawmhnaw ang chi thil nêm, awlsam taka luh theih atan hman a ni.

 

Decoder hi a tam zawk chu non-contact device decoding height engemaw zat nei an ni. Cashier-in thil a check out emaw, bag-a a dah emaw chuan electronic tag chu degaussing area khawih lovin a decode thei a ni. Thil zawrh chu decode lohvin dawr aṭanga a chhuah chuan detector chuan alarm a tichhuak ang a, cashier, customer leh store security personnel-te chu a rang thei ang bera enkawl turin a hriattir ang.

 

Electronic Article Surveillance (EAS) system hian customer te chu surveillance system angin a ti nuam lo a, deterrent angin a thawk bawk. EAS system-ah hian technology lian pali a awm a, chungte chu radio frequency, electromagnetic, microwave, leh acousto-magnetic technology te an ni. A tlangpuiin electromagnetic leh RF thil siamte hi a man a tlawm zawk a, an tag te hi thil zawrh emaw, bungrua emaw-ah a nghet reng a, microwave leh acousto-magnetic tag erawh a man a to zawk thung.
