High frequency vs. Ultra - high frequency?

HF vs. UHF RFID: Ungasarudza sei iyo chaiyo

RFID tech inouya mumhando dzakasiyana, uye maviri akajairika ariHigh Frequency (HF)uyeUltra - high frequency (uhf). Ivo vanoshanda zvakasiyana, mutengo nenzira dzakasiyana, uye vanoshandiswa pazvinhu zvakasiyana. Kutora zvisiri izvo kunogona kutambisa nguva nemari.

1. Ndeupi mutsauko?

High Frequency (HF) - 13.56 MHz

Range:Pfupi (mashoma masendimita kusvika kutsoka).

Zvakanakira:Chengetedzwa, vhara - kumusoro mabasa.

Inoshandiswa mu:Makadhi ekuwana (hofisi mabheji), kubhadhara zvisina kufanira (Apple kubhadhara, makadhi echikwereti), mabhuku emafirabhu.

Pros:Inoshanda zviri nani padoro nesimbi, inotsigira encryption, yakafanana pasi rese.

Cons:Iwe unofanirwa kusvika padhuze kuti utarise.

Ultra - high frequency (uhf) - 860-960 mHz

Range:Kureba (akati wandei tsoka kusvika pamakumbo makumi maviri).

Zvakanakira:Kurumidza, kuwanda kwekutarisa.

Inoshandiswa mu:Inventory yekutevera (retail, warehouse), kutumira mapepa ekutakura, kuteedzera kwemidziyo.

Pros:Inoverenga matagi mazhinji kamwechete, zviyero zvematimu, renji refu.

Cons:Haishande nemazvo padhuze nesimbi kana zvinwiwa, zvakachengetedzeka, frequency mitemo inosiyana nenyika.

2. Ndeupi waunofanira kushandisa?

Sarudza HF kana:
Iwe unoda chengetedzo (sekubhadhara kana kuwana kutonga).
✔ Uri kukatira zvinhu zviri pedyo nezvinwiwa kana simbi.
✔ Iwe unoda hurongwa hwepasi rose.

Muenzaniso:Shopu yekofi uchishandisa RFID Kuvimbika Makadhi {{0} Vatengi vanongopeta voenda.

Sarudza UHF kana:
Iwe unofanirwa kutarisa kubva kure.
✔ Uri kuteedzera zvinhu zvakawanda nekukurumidza (kunge imba yekuchengetera).
Iwe unoda iyo yakachipa mhando inogona kuitika.

Muenzaniso:Chitoro chekupfeka chekuputika chinotarisa mazana ezvinhu kamwechete - uhf zvinoita mumasekondi.

3. Zvinetso Zvakafanana

Metal & zvinwiwa:UHF masaini anokanganiswa navo. Hf anozvibata zviri nani.

Nyika Mitemo:UHF frequencies inosiyana (semuenzaniso, US vs. Europe). HF inoshanda zvakafanana kwese kupi.

Kukanganiswa tag:UHF inogona kuongorora akawanda mabiki kamwechete, asi dzimwe nguva vanokanganisa mumwe nemumwe.

4. Chisarudzo chekupedzisira

Hf=}}}}} - kumusoro, yakachengeteka, yakavimbika.(Kubhadhara, id makadhi, kudiki kwekutevera).

UHF=kureba {}}} range, yakawanda scanning, mutengo wakaderera.(Warehouses, retail, hombe dzinza).

Uchine chokwadi? Bvunza:

Unoda kuongorora kure uye nekukurumidza? → uhf.

Unoda kuchengetedzwa kana kushanda pedyo nesimbi / mvura? → HF.

Mamwe masisitimu anotoshandisa zvese, asi izvozvo zvakaoma. Ichengete iri nyore {{1} inotora iyo inokodzera zvaunoda.
