Active leh Passive RFID inkar danglamna leh inzawmna .

RFID (radio frequency identification), "electronic tags" tia hriat lar chu non-Contact automatic identification technology a ni a, target object te chu automatic in a hriat theih a, radio frequency signal hmangin data relevant tak tak a hmu bawk. Identification hna hian kut hmanga inrawlh a ngai lo va, a hnathawh ber chu data ziah leh chhiar a ni. Tag, tawnglettu, leh data transmission leh processing system hmanga siam a ni. Electronic tag-ah hian battery dah a nih leh nih loh a zirin chi hnih ah then a ni a, active leh passive.

 

Tunah hian passive electronic tags hian market 80% a luah a, active electronic tags erawh chuan 20% aia tlem chauh a luah thung. Chuti a nih chuan active tag leh passive tag te hi eng nge an danglamna leh an inzawmna?

 

1. A awmzia sawifiahna .

Active RFID, Active RFID tia hriat bawk hi internal battery hmanga siam vek a ni. Chutih rual chuan, battery-a energy supply ṭhenkhat chu electronic tag leh chhiartute inbiakpawhna atana mamawh RF energy-ah a chang a, a tlangpuiin remote identification a thlawp a ni.

Passive tags, passive tag tia hriat bawk hian card reader-in a puan microwave signal an dawn hnuah microwave energy engemaw zat chu anmahni hnathawhna atan direct current-ah an chantir thei a ni. Passive RFID tag pakhatin RFID card reader a hnaih chuan passive RFID tag antenna chuan electromagnetic wave energy dawn chu electrical energy-ah a chantir a, RFID tag-a chip chu a activate a, RFID chip atanga data chu a thawn chhuak a ni. Anti-interference ability hmang hian standard data chhiar leh ziah dan tur an siam danglam thei a, specialized application system-ah pawh a hlawk zawk leh a hlawk zawk a, meter 10 chuang zeta hlaah a awm thei bawk.

 

2. Hnathawh dan tur thurin .

Active electronic tags tih hian battery hmanga energy pek hmanga hnathawk tags a kawk a ni. Battery, memory leh antenna te hian active electronic tag an siam a, chu chu passive RF activation method nen a danglam a, battery thlak hmain set frequency band hmangin information a thawn chhunzawm zel a ni.

Passive RFID tags performance hi tag size, modulation form, circuit Q value, device power consumption, leh modulation depth te hian nasa takin a nghawng a ni. Passive RF tag hian memory capacity 1024bits a nei a, ultra wide operating frequency band a nei bawk a, hei hian industry dan kaihhnawih a zawm a, flexibly developed leh applied theih a ni bawk. Tag tam tak chu a rualin a chhiar thei a, a ziak thei bawk. Passive RF tag design, battery mamawh a awm lo, memory vawi 100000 aia tam erase theih a ni.

 

3.Hman man leh rawngbawlna nun .

Active RFID: man to tak leh battery a rei lo hle.

Passive RFID: Active RFID nena khaikhin chuan a man a tlawm hle a, battery life pawh a rei hle.

 

4.A thatna leh a that lohna .

(1)Active RFID tags te hi built- battery hmanga power pek an ni a, tag hrang hrang hian battery number leh shape hrang hrang an hmang a.

A thatna: Operation distance rei tak, active RFID tag leh RFID reader inkar hlat zawng chu meter sawm vel, a nih loh leh meter za tam tak pawh a thleng thei.

A that lohna: A lian hle a, a man a to a, battery life a neih avangin hman hun a tlem bawk.

(2)Passive RFID tag ah hian battery a awm lo va, a electrical energy chu RFID reader atanga lak a ni. Passive RFID tag hian RFID reader a hnaih chuan passive RFID tag antenna chuan electromagnetic wave energy dawn chu electrical energy-ah a chantir a, RFID tag-a chip chu a activate a, RFID chip atanga data chu a thawn chhuak a ni.

A thatna: A lian lo, a rit lo, a man tlawm, service life rei tak, a lem chi hrang hrang, sheet emaw hook emaw ang chi siam theih a ni a, environment hrang hrangah hman theih a ni bawk.

A that lohna: Internal power supply a awm loh avangin passive RFID tag leh RFID reader inkar hlat zawng hi a tlem hle a, a tlangpuiin meter tlemte chhunga awm a ni. A tlangpuiin high-power RFID reader te hi an mamawh a ni.
