Dɛn nti na RFID agye din saa?

RFID (radio frequency identification) mfiridwuma, a wɔsan frɛ no wireless radio frequency identification technology, yɛ nkitahodi mfiridwuma a ɛde radio nsɛnkyerɛnne di dwuma de nya non{0}}ne automatic identification di nkitaho. Ɛnam radio frequency a wɔmfa nhama nkɔ so so na ɛyɛ data nkitahodi akwan abien so, a ebetumi ahu na akenkan/akyerɛw nsɛm wɔ ɛlɛtrɔnik tag anaa radio frequency card so, na ɛnam so awie data nkitahodi a ɛda akenkanfo ne tag ahorow ntam na wɔahu botae ahorow na wɔasesa data.

Nnyinasosɛm ahorow a ɛfa RFID a ɛwɔ akyirikyiri ho .
1) Nsiesiei a ɛfa RFID a ɛwɔ akyirikyiri ho .
Ansa na wobɛsua RFID a ɛwɔ akyirikyiri no nnyinasosɛm ho ade no, ɛho hia sɛ wosua RFID nhyehyɛe ho ade. RFID nhyehyɛe no wɔ afã abiɛsa: ɛlɛtrɔnik tag, akenkanfo ne akyerɛwfo, kɔmputa, ne wɔn application nhyehyɛe ahorow. Ɛlektrɔnik tags no yɛ nea wɔasisi no titiriw-wɔ antenna ne circuit chips mu, a ɛwɔ adwuma a ɛne sɛ wobewie nkitahodi a ɛne RF antennas. Ɔkenkanfoɔ no yɛ afã anan titire: antenna, control unit, wireless transceiver front-end, ne communication interface. Ne dwumadi titiriw ne sɛ ɛbɛkenkan anaa akyerɛw ɛlɛtrɔnik tag ahorow ho nsɛm. Kɔmputa ne application software dwumadi ahorow no nam akenkanfo ne akyerɛwfo nkitahodi so na ɛka kɔmputa a ɛwɔ akyi no ho, anaasɛ ɛne Upper Master Station nhyehyɛe no hyia na ama wɔanya data a wɔde sesa.
2) Adwumayɛ nnyinasosɛm a ɛfa akyirikyiri RFID ho .
Ɔkenkanfo ne ɛlɛtrɔnik tag yɛ mmuaemafo, na ne nnyinasosɛm a ɛyɛ adwuma no te sɛ nea edidi so yi. Ɔkenkanfoɔ no de radio asorɔkye ahoɔden a ɛyɛ frequency pɔtee bi kɔ transformer no so, ɛma transformer circuit no kɔ so de data a ɛwɔ mu no mena, na afei ɔgye nsɛm no nnidiso nnidiso na ɔkyerɛ aseɛ de di dwuma no ho dwuma sɛdeɛ ɛfata.

RFID nhyehyɛe a ɛwɔ akyirikyiri no su ahorow .
Mprempren, passive remote RFID nhyehyɛe ahorow no wɔ frequency bands abien a ɛyɛ adwuma: UHF ne 2.45 GHz. Passive Ultra-High frequency systems wɔ akenkan ne akyerɛw kwan a ɛboro mita 10, a ɛware sen 2.45 GHz nhyehyɛe, na ɛma ɛyɛ akyirikyiri nkyerɛkyerɛmu nhyehyɛe no fã titiriw. Mfaso a ɛwɔ so titiriw ne nsɛm a edidi so yi:
Bere ankasa: bere ankasa mu mmuae, ID nɔma akenkan a ɛyɛ adwuma ankasa, a ebetumi anya saa nsɛm no.
Anti counterfeiting: Wɔrentumi nyɛ microwave display a wɔayɛ no ho mfonini, nsakra, anaasɛ wɔnyɛ ho mfonini.
Nkitahodi: Nneɛma a wɔde kɔ amannɔne a wɔhwɛ so denam kɔmputa so nkitahodi so.
Pɛpɛɛpɛyɛ: Akenkan ho nsɛm a ɛyɛ nokware no kɔ soro kodu 99.99%.
Ɛka a ɛba fam: Sɛ wɔde di dwuma a, ɛho ka yɛ yuan kakraa bi pɛ.
Ahotoso: Ɛfa nneɛma a atwa yɛn ho ahyia tebea a emu yɛ den te sɛ mfutuma, nsu, ne nea ɛkeka ho ho.
Nkwa tenten: Battery biara ho nhia bere a wɔde di dwuma, passive card nkutoo na ɛho hia, ɛho nhia sɛ wosiesie wo nkwa nna nyinaa.

RFID nhyehyɛe a ɛwɔ akyirikyiri no fa wireless transmission mode, na wireless tebea no yɛ den yiye. Enti, nneɛma pii ka akenkan ne kyerɛw kwan a ɛwɔ akyirikyiri RFID nhyehyɛe no so, a nsɛm a edidi so yi ka ho titiriw:
Nneɛma titiriw a ɛka akenkan ne akyerɛw kwan a RF kaad ahorow no fa so ne RF ahoɔden a ɛwɔ akenkanfo no mu, ahoɔden a ɛda adi, tumi a RF kaad no de di dwuma, ahoɔden a wonya ne sɛnea ɔkenkanfo no te nka.
2. Nneɛma a ɛka atifi hɔ nsɛnkyerɛnneɛ no ne RF card antenna no fã a ɛgye na ɛda adi yie wɔ cross-sectional area ne antenna antenna beaeɛ a ɛtu mpɔn a ɛwɔ akenkanfoɔ/ɔkyerɛwfoɔ no mu.
Sɛ frequency no kɔ soro wɔ field of view koro no ara ase a, passive RFID system no adwumayɛ so tew.
