Kodi AnRFID ReaderKodi?

Nachi china chomwe palibe amene angakuuzeni pamisonkhano ya RFID: theka la owerenga omwe adayikidwa m'malo osungira zinthu pakali pano akuchita zoyipa kuposa makina a barcode omwe adalowa m'malo. Osati chifukwa luso laukadaulo silikugwira ntchito-zimagwira-koma chifukwa makampani amagula owerenga momwe amagulira zida zina zilizonse, ndipo vuto ndi lomweli.

 

Ndakhala zaka khumi ndi ziwiri ndikuwona mabizinesi akuwotcha ndalama za RFID. Bungwe la RAIN Alliance limatha kudzitamandira pafupifupi ma tag 52.8 biliyoni omwe adatumizidwa chaka chatha, koma chomwe sasindikiza ndi kuchuluka kwa ma tag omwe sanawerengedwe bwino, kapena kuwerengedwa nthawi makumi awiri pomwe amayenera kuwerengedwa kamodzi, kapena kuwononga machitidwe onse owerengera chifukwa wina adaganiza zowerenga molakwika-malo olemera.

Chifukwa chake tiyeni tikambirane zomwe owerenga RFID amachita, zomwe zimasweka, komanso momwe osataya ziwerengero zisanu ndi chimodzi pozindikira.

What Does An RFID Reader Actually Do?

 Ntchito Yowerenga (Yosavuta Kuposa Ogulitsa Imamveka)

 

Chotsani malonda ndipo wowerenga amachita zinthu zitatu: amalira m'chipinda, amamvetsera mayankho, ndikuzindikira zomwe zimabwerera. Ndichoncho. Zovuta zimakhalamoBwanjiimachita zinthu zimenezo.

Yankho lofulumira:Wowerenga RFID ndi zida zomwe zimapanga wailesi, kutumiza malamulo kuma tag ogwirizana a RFID, kulandira kuyankha kwa tag, zosefera zomwe zimawerengedwa, ndikutumiza ma tag ku mapulogalamu. Mu machitidwe ogwira ntchito, owerenga samangokhalira "scanner"; ndi malo owongolera a RF omwe amasankha kuti ndi liti, kuti, komanso momwe ma tag data imakhalira bizinesi.

 RFID Reader vs. Tag vs. Antenna: Zomwe Gawo Lililonse Limachita

 

Osaka nthawi zambiri amasakaniza owerenga, tag, ndi mlongoti. Chizindikirocho chimakhala ndi chizindikiritso. Mlongoti umapanga malo owerengera. Owerenga amawongolera gawoli, amapatsa mphamvu ma tag akafunika, amasankha yankho, ndikutumiza deta yoyera ku makina ochezera. Kuti mumve zambiri za kusinthana kwa mpweya{4}, onani bukhulimomwe ma tag a RFID amalankhulirana ndi owerenga.

 

Gawo la dongosolo Ntchito yayikulu Zomwe zingasokonezeke
RFID tag Imasunga EPC, UID, kapena data ya ogwiritsa ntchito yomwe imazindikiritsa chinthucho. Chip cholakwika, kapangidwe ka mlongoti kofooka, kusayika bwino, kutulutsa zitsulo, kuyamwa kwamadzi.
RFID mlongoti Amapanga malo enieni owerengera ndikusankha polarization, m'lifupi mwake, ndi mawonekedwe ake. Kupitilira{{0}kuwerenga, ma blind spots, bad angle, wrong gain, cable loss.
Wowerenga RFID Imawongolera mphamvu, kudumphadumpha pafupipafupi kapena kugwiritsa ntchito tchanelo, kukana -kugundana, kulamula ma tag, kusefa, ndi kutulutsa deta. Kusamva bwino kwa olandila, kusagwira bwino-kugundana, kuthandizira kofooka kwa API, kusakwanira kwa chilengedwe.

 

 

Mukawonjezera owerenga mphamvu, imapanga mphamvu ya RF pamtundu uliwonse wamtundu womwe mumagwiritsa ntchito-125 kHz pazinthu zoyandikana ndi sukulu yakale, 13.56 MHz ngati mukuchita NFC kapena makina a library, kapena 860-960 MHz pamakina a UHF omwe aliyense akugwiritsa ntchito pano. Mphamvu imeneyi imadutsa mu mlongoti kupita kumalo amene mavenda amachitcha kuti "read zone" koma zomwe zimaoneka ngati zosaoneka za ma elekitiromagineti zomwe zimasintha mawonekedwe potengera chitsulo chapafupi, kachulukidwe konkire, komanso ngati wina wayimitsa forklift pamalo olakwika.

Kwa ma tag opanda pake (omwe ndi 95% ya zotumizidwa), chizindikirocho chimagwira ntchito ziwiri. Imapatsa mphamvu chipu cha tag NDIPO imanyamula lamulo lofunsa mafunso. Chizindikirocho chimadzuka, chimasintha chizindikirocho ndi deta yake, ndikuchibwezeretsanso kwa owerenga. Siginecha ya backscatter iyi imabwereranso ndi mphamvu yotsika modabwitsa-tikulankhula 60-70 dB pansi pa zomwe zidatumizidwa, kutanthauza kuti ngati wowerenga akukuwa 1 watt, tagyo imanong'onezanso pa 0.0000001 watts.

Wolandira wowerenga amayenera kusankha kunong'oneza komweko mwa kufuula kwake. Ichi ndichifukwa chake owerenga ndi otchipa-amakonda kulandila, ndipo mwadzidzidzi mtundu wanu wotsatsa wamamita 10 umakhala 3 metres ndi zinthu zenizeni pamashelefu enieni.

 

Kusinthana konse kumatenga 3-20 milliseconds pa tag, kutengera kuchuluka kwa data yomwe mukusuntha komanso protocol yomwe mukuyendetsa. Mofulumira kwambiri kotero kuti imamveka nthawi yomweyo, pang'onopang'ono mokwanira kuti ngati mukuyesera kuwerenga ma tag 500 akuwuluka pa conveyor pa 2 metres pamphindikati, muyenera kuchita masamu.

 

 The Reader's Job (Simpler Than Vendors Make It Sound)

 

 Chifukwa Chake Zolemba Zanu Zowerengera Ndi Mabodza

 

Malo aliwonse ogulitsa a RFID amawonetsa chithunzi chofanana: wowerenga wolumikizidwa ndi mlongoti, wokhala ndi arc yabwino yowonetsa zowerengera. "Mpaka 12 metres!" amati. Ndipo mwaukadaulo, sakunama. M'chipinda cha RF anechoic, chokhala ndi tag yoyang'ana bwino, kutentha koyenera, popanda kusokoneza, chokwera thovu, mutha kugunda mamita 12.

 

M'nkhokwe yanu? Mudzapeza mamita 4-6 patsiku labwino.

Izi ndi zomwe zimadya mtundu wanu:

 

 Ma tag amakupha poyamba.

UHF RFID ndi polarization-yovutirapo. Ngati mlongoti wa tag yanu ndi wosiyana ndi kukhazikika kwa mlongoti wa owerenga, kuchuluka kwa zomwe mumawerenga kumatsika ndi 90%. Ichi ndichifukwa chake kukhazikitsa ma portal kumafunika tinyanga zinayi zosachepera-mukuyesera kuyika njira zonse zomwe bokosi lingadutse pakhomo. Ndidawona malo ogawa akugwiritsa ntchito $ 80K pa owerenga ndi tinyanga wina asanazindikire kuti mabokosi awo amalata adayang'ana madigiri a 90 kuchokera pazomwe ophatikizawo amaganizira. Adamaliza kuonjeza tinyanga zina ziwiri ndipo sanafikire zomwe amawerengera.

 Chitsulo chili paliponse ndipo chimakudani.

Ikani chizindikiro cha RFID pazitsulo ndipo akabudula achitsulo atulutse mlongoti wa tagiyo. Chizindikirocho chimakhala chakuda. "Koma tidagula pa-ma tag achitsulo!" Zedi, ndipo iwo amagwira ntchito bwino mu labu. M'menemo, mumazindikira kuti "pa{4}}zitsulo" amatanthauza "chophwanthira pazitsulo" ndipo ma tag anu amakhala pamabokosi omwe nthawi zina amatsutsana ndi zitsulo, nthawi zina osati, nthawi zina pamakona. Tsopano mukulimbana ndi mawonetsedwe ochulukirachulukira pomwe chizindikirocho chimadumphadumpha patatu musanagunde chizindikirocho, ndipo mawerengedwe anu a mita 8 amakhala ma 8 centimita. Kapena 12 metres. Kapena imawerenganso tag yomweyi nthawi makumi anayi chifukwa chizindikirocho chikuyenda mozungulira ngati pinball.

 Madzi amatenga RF pa 900 MHz

monga inu simungakhulupirire. Pallets madzi a m'mabotolo? Maloto owopsa. Chilichonse chokhala ndi madzi ambiri? Iwalani zowerengera zosasintha. Pali chifukwa chake ogulitsa zovala amakonda RFID-ma tag a nsalu amamveka ngati oyera. Koma yesani kutsatira masupu am'chitini ndipo mumvetsetsa chifukwa chake kugawa chakudya sikuchedwa kutengera.

 Chingwe chimakhala chofunikira kuposa momwe aliyense amavomerezera.

Chingwe chamamita 10-chimayenda kuchokera pa owerenga anu kupita ku mlongoti wanu? Mwangotaya 5 dB, zomwe zikutanthauza kuti pafupifupi theka la gawo lanu lowerenga. Gwiritsani ntchito chingwe chotsika mtengo ndipo mumataya zambiri. Ndapeza "owerenga olephera" omwe anali owerenga abwino kwambiri olumikizidwa ndi chingwe cha bargain-basement chomwe chinali kutaya 8-9 dB. Bwezerani $ 40 ya chingwe, mwadzidzidzi dongosolo limagwira ntchito.

 

 Kusankha pafupipafupi Palibe Amene Akufotokoza Moyenera

 

Muli ndi magulu atatu oti musankhe, ndipo mtengo wachigamulo ndi wosavuta kuposa momwe ogulitsa amayerekezera:

 

125 kHz (LF)

ngati mukuyika nyama, muyenera kuwerenga m'madzi, kapena muli ndi malamulo omwe amakukakamizani pano. Kutalika kwa masamba ndi 10 cm. Kutumiza kwa data kumachedwa. Ma tag amawononga $2-5 iliyonse. Pafupifupi palibe amene angasankhenso izi pokhapokha atayenera kutero.

 

13.56 MHz (HF)

ngati mukulipirira, kuphatikiza mafoni a NFC, makina a library, kapena kutsatira zamankhwala komwe mukufunikira tag-level chitetezo. Chiwerengero chowerengera chili pansi pa mita. Ma tag ndi otsika mtengo ($0.10-0.50). Muyezo wa ISO 15693 umagwira ntchito kwa onse ogulitsa, zomwe ndizosowa m'dziko la RFID. Gululi limakhomerera kuposa kulemera kwake pamapulogalamu enaake koma anthu ogulitsa nthawi zambiri amadumpha chifukwa kuchuluka kwake kumachepa.

 

860-960 MHz (UHF)

kwa china chirichonse. Apa ndi pamene voliyumu ili, komwe kuli zatsopano, komwe kuli mavuto. Masanjidwe owerengera amatha kugunda mamita 10+ ndi zida zabwino komanso momwe zilili bwino. Ma tag amawononga $0.05-0.15 mu volume. Mutha kuwerenga ma tag mazana pamphindikati. Koma mumalipira ntchitoyo ndi kusokoneza kwazitsulo zovuta, kuyamwa kwamadzimadzi, kugawikana kwadongosolo m'magawo onse, komanso malo owerengera omwe amafunikira uinjiniya weniweni wa RF kuti ayende bwino.

Chigawo chowongolera ndi choyipa kuposa momwe chiyenera kukhalira. Kumpoto kwa America kumapeza 902-928 MHz ndi frequency hopping, komwe kumakhala koyera. Europe imakakamira ndi 865-868 MHz ndi kumvera koyenera-isanalankhule-ma protocol omwe amakupangitsani kuti muthe kuchita chilichonse. Asia yagawika ndi dziko. Ngati mukutumiza padziko lonse lapansi, mumagula owerenga omwe akukhudzana ndi dera kapena mumagula owerenga omwe amathandizira magulu angapo ndikuvomereza kuti amawononga ndalama zambiri kuposa mayunitsi okongoletsedwa ndi dera.

 Ndi RFID Reader Frequency Iti Imakwanira Pulojekiti Iti?

 

Kusankha pafupipafupi kuyenera kuyamba ndi kayendetsedwe ka bizinesi, osati kalozera. Pulojekiti ya ziweto, makhadi a hotelo, ntchito-mu-pamalo ochitirako zinthu, ndi padoko-zolowera pakhomo zonse zitha kugwiritsa ntchito RFID, koma sizikufunika wowerenga yemweyo. Kutumiza kwapadziko lonse kwa UHF kumamangidwa mozungulira kulumikizana kwa EPC Gen2 / ISO 18000-6C; GS1 imafotokoza zakeEPC Gen2 air interface protocolmonga zofunikira zakuthupi ndi zomveka zamakina a UHF RFID.

 

Mtundu wa owerenga Zokwanira bwino Zowopsa zogula Lamulo losankha bwino
Wowerenga LF, 125 kHz / 134.2 kHz Animal ID, zidziwitso zosavuta zofikira, mapulogalamu omwe amafunikira mawerengedwe aafupi-owongolera osiyanasiyana. Kuyembekezera utali wautali kapena kuchuluka kwa tag kuchokera ku hardware ya LF. Sankhani LF mukamayang'aniridwa moyandikira-kuwerenga kosiyanasiyana ndikofunikira kuposa liwiro kapena mtunda.
Owerenga HF / NFC, 13.56 MHz Makadi, ma tag a NFC, malaibulale, malipiro-monga kucheza,-tap workflows. Kugwiritsa ntchito HF pomwe ogwiritsira ntchito amafunikira mita -zowerengera zowerengera. Sankhani HF pakafunika chitetezo, kugwirizana kwa foni, kapena kugunda mwadala.
Wowerenga UHF, 860-960 MHz Malo osungiramo katundu, zovala, ma portal a pallet, katundu wobweza, chizindikiritso cha zinthu zambiri. Kugula kuchuluka kokwanira popanda kufotokozera malire owerengera.
