Ɛlektrɔnik tag no yɛ RFID nhyehyɛe no data soa, a ɛyɛ tag antenna ne tag pɔtee chip. RFID Reader/Writer no ne mfiri titiriw a wɔde kenkan data. Momma yɛnhwɛ sɛnea RFID akenkanfo ne ɔkyerɛwfo bi yɛ adwuma.

 

1. Nea ɛyɛ RFID mfiridwuma .

RFID Radio Frequency Identification yɛ non{0}}nkitahodi mfiridwuma a ɛyɛ adwuma ankasa a ɛkyerɛ nneɛma a wɔde asi wɔn ani so no ankasa na ɛnam radio frequency nsɛnkyerɛnne so nya data a ɛfata. Adwuma a wɔde kyerɛ sɛ obi yɛ no nhwehwɛ sɛ ɔde ne nsa yɛ adwuma na ebetumi ayɛ adwuma wɔ mmeae ahorow a ɛyɛ den.

2. Dɛn ne RFID nhyehyɛe ahorow a ɛka ho .

Anyɛ yiye koraa no, RFID nhyehyɛe no wɔ afã abien: ɛlɛtrɔnik tag ne ɔkenkanfo/ɔkyerɛwfo. Sɛnea akwan horow a wɔfa so de anyinam ahoɔden di dwuma no kyerɛ no, wobetumi akyekyɛ ɛlɛtrɔnik tag ahorow mu ayɛ no tag ahorow a ɛyɛ adwuma, tag a ɛnyɛ adwuma, ne tag a ɛyɛ semi&passive. Wɔde batere ahyɛ ɛlɛtrɔnik tag a ɛyɛ adwuma no mu, bere a passive RF tag no nni battery a ɛwɔ mu. Semi&passive tag no fã bi gyina battery no so ma ɛyɛ adwuma.

Wobetumi akyekyɛ ɛlɛtrɔnik tags mu ayɛ no low{}}frequency electronic tags, high-frequency electronic tags, Ultra-a ɛkorɔn frequency electronic tags, ne microwave electronic tags a egyina frequency ahorow so. Sɛnea nneɛma ahorow a wɔde kyekyere nneɛma ho no kyerɛ no, wobetumi akyekyɛ mu ayɛ no credit card so nkyerɛwde, nkyerɛwde a wɔde kyerɛw nsɛm, krataa a wɔde kyerɛw nneɛma, ahwehwɛ a wɔde hyɛ ahwehwɛ mu, nkyerɛwde a ɛyɛ kurukuruwa, ne nneɛma titiriw a wɔde di dwuma daa.

RFID akenkanfoɔ no ne RFID ɛlɛtrɔnik tags di nkitaho wireless so denam antenna so, na ɛma wotumi kenkan anaa wɔkyerɛw tag identification codes ne memory data. Ɔkenkanfoɔ/ɔkyerɛwfoɔ a ɔtaa yɛ no bi ne-frequency modules (transmitter ne receiver), control units, ne reader/writer antennas.

 

3. RFID akenkanfo/ɔkyerɛwfo adwumayɛ nhyehyɛe .

RF nsɛnkyerɛnne a ɛwɔ ɛlɛtrɔnik tag ne akenkanfo ntam no ho ahunmu (a wɔne wɔn ho wɔn ho nni nkitaho) no nam nneɛma a ɛka bom so na ɛba. Wɔ coupling channel no mu no, ahoɔden a wɔde kɔ baabi foforo ne data a wɔde sesa no gyina bere mu abusuabɔ so na ɛba. Adwumayɛ nhyehyɛe pii ma RFID nhyehyɛe, dɛn ne adwumayɛ nhyehyɛe ma RFID nhyehyɛe .

 

RFID akenkanfo/ɔkyerɛwfo no adwumayɛ kwan a ɛde akwankyerɛ ma:

1. Application Layer Program no de ahyɛdeɛ bi ma sɛ wɔbɛfrɛ tag recognition layer module no, a ɛma akwankyerɛ a ɛbɛma woanya tag a wɔde bɛmena no na ɛde akɔma baseband processing module no.

2. Baseband processing module no encodes na ɛsakra label recognition layer akwankyerɛ no ma ɛyɛ baseband signal, a wɔakyekyɛ mu ayɛ no akwan mmienu na ɛde fa interface no so.

3. Wɔde data no ahyɛ serial baseband sɛnkyerɛnne mu na wɔde kɔ RF anim-End module no so.

4. Serial baseband signal no hyɛn RF anim-End module no mu, ɛfa nsakrae, tumi a ɛma ɛyɛ kɛse, ne upconversion ansa na wɔayɛ no modulated akɔ ultra-High frequency band no so, na afei wɔde akɔ bandpass filter no mu akɔyɛ filtering.

5.Wɔ filtering akyi no, wɔde sɛnkyerɛnne no kɔ power amplifier no so ma ɛma amplification, na afei wɔde kɔ antenna no so ma wɔde kɔ.

 

RFID akenkanfoɔ no adwumayɛ kwan a wɔfa so nya label backscatter data ho nsɛm:

1. RFID electronic tag no nya nsɛnkyerɛnne bi fi ɔkenkanfo no hɔ, nya ahoɔden, na ɛnam tumi a ɛwɔ so no yɛ adwuma. Ɛhyɛ aseɛ yɛ akenkanfoɔ ahyɛdeɛ no na ɛkyerɛ sɛ mmuaeɛ bi ho hia anaa. Sɛ mmuaeɛ bi ho hia a, wɔde mmuaeɛ ho nsɛm no kɔ RF anim-End module no so fa antenna no so wɔ backscatter kwan so.

2. RF anim-End module no de nsɛnkyerɛnne a wɔagye no kɔ bandpass filter so ma ɛyɛ filter. Afei filtering, carrier sɛnkyerɛnne no san kɔ baseband sɛnkyerɛnne na ɛde fa afã horow te sɛ dede a ɛba fam amplifier, down conversion, ne nsakrae.

3. Wɔde data no kɔ baseband processing module a ɛwɔ PC no mu denam interface bi so.

Ɛdenam atifi hɔ nhyehyɛe no so no, RFID nhyehyɛe no anya nsɛm a wohu ne data a wɔde mena yiye, na ɛma wonya fapem a wotumi de ho to so a wɔde bedi dwuma kɛse wɔ mfiridwuma a ɛma wohu nneɛma a ɛnyɛ adwuma a ɛma wotumi hu ade ho.
