Difrens mo koneksen bitwin aktiv mo pasiv RFID

RFID (Radio Frequency Identification), commonly known as "electronic tags", is a non-contact automatic identification technology that automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require manual intervention, and its main function is to write and read data. It consists of tags, interpreters, and data transmission and processing systems. According to whether the electronic tags are equipped wantaim ol bateri, ol i bruk i go long tupela kain: wok na pasiv.

 

Long nau, ol pasiv ilektronik tag i save kamapim 80% bilong maket, na ol ektiv ilektronik tag i save kamapim tasol liklik long 20%. Olsem na wanem ol samting i narapela narapela na koneksen namel long ol ektiv tag na ol pasiv tag?

 

1. Tok klia

Active RFID, ol i save kolim tu olsem ektiv RFID, i save kisim pawa olgeta long ol intanel bateri. Long wankain taim, sampela eneji saplai bilong bateri i save tanim i go long RF eneji ol i nidim bilong toktok namel long ol ilektronik tag na ol rida, we ol i save sapotim rimot aidentifikesen.

Ol pasiv tag, ol i save tu olsem ol pasiv tag, ol i ken tanim sampela maikrowev eneji i go long dairek karent bilong wok bilong ol yet bihain long ol i kisim maikrowev signal em kad rida i tokaut long en. Taim wanpela pasiv RFID tag i kam klostu long wanpela RFID kad rida, antena bilong pasiv RFID tag i kam long RFID tag i tanim i go insait long data bilong lektrik, na i salim chip i kam long data bilong em i go insait long lektrik eneji, na i salim chipnetik wev eneji i go insait long lektrik, na salim i go long chipel wev eneji ol i kisim i go insait long elektrik eneji, na i salim ol i kam insait long wok bilong chipik i go insait long lektrik eneji, na i salim ol i kam insait long wok bilong em long kisim data, na i salim ol i go insait . chung. Wetem abiliti blong anti-interferens, ol yusa oli save mekem riding mo raet blong ol standet data, mekem se i moa gud mo i wok gud long ol spesel aplikesen sistem, wetem wan distens blong rid blong ova 10 mita.

 

2. prinsipol bilong wok

Ol 'active elektronik tag' i makim ol 'tag' we i wok wantaim eneji we ol bateri i givim . bateri, memori, na 'antenna' wantaim i kamapim wanpela 'active elektronik tag', we i narapela kain long rot bilong pasim RF na i save salim infomesen i go long wanpela set frikwensi ben pastaim long ol i senisim 'battery replacation.

The performance of passive RFID tags is greatly influenced by tag size, modulation form, circuit Q value, device power consumption, and modulation depth. The passive RF tag has a memory capacity of 1024bits and an ultra wide operating frequency band, which meets relevant industry regulations and can be flexibly developed and applied. It can read and write multiple tags at the same time. Passive RF tag disain, i no gat bateri i mas kamap, memori inap long rausim planti taim moa long 100000 taim.

(1)Ol mak bilong RFID i gat wok i gat pawa long ol bateri i stap insait, na ol narapela narapela tag i yusim ol narapela narapela namba na seip bilong ol bateri.

Ol gutpela samting: longpela wok longwe, longwe namel long ektiv RFID tag na RFID rida i ken kamap long tenpela mita, o iven planti handet mita{{0}

Ol samting i no gutpela: Bikpela sais, bikpela kos, na taim bilong yusim i liklik bikos long laip bilong bateri.

(2)Passive RFID tag i no gat battery, na elektrikal enaji bilong en i kam long RFID reader. Taim passive RFID tag i kam klostu long RFID reader, antenna bilong passive RFID tag i senis elektromagnetik wev enaji i likim long elektrikal enaji, aktivim chip long RFID tag, na sendim ol data long RFID chip.

Ol gutpela samting: Liklik sais, lait weit, liklik kos, longpela sevis laip, ol i ken wokim i kamap ol narapela narapela seip olsem ol liklik pepa o huk, na putim long ol narapela narapela envairomen{{0}

Disavantej: Bikos i no gat pawa saplai insait, longwe namel long ol pasiv RFID tag na ol RFID rida i sot, planti taim insait long sampela mita{0}} Planti taim, ol hai-pawa RFID rida i mas kisim.
