Amathegi e-RFID Angafundwa Kude Kangakanani?

 

Amathegi asebenzayo asebenza ebangeni elifushane. Omaka abasebenzayo basebenza kude kakhulu. Izinombolo eziqondile zincike ezintweni ezisetshenziswayo, imvamisa, nokuthi yini phakathi komaka nomfundi.

 

Impendulo ibalulekile manje ngoba iQualcomm ithe ngonyaka odlule izofaka abafundi be-UHF RFID kuma-chips efoni. I-Zebra yathumela ifoni yebhizinisi enomfundi-owakhelwe ngaphakathi ngoJanuwari. I-RAIN Alliance yamemezela iphrojekthi evamile ye-smartphone ngoMashi. Uma le mizamo iphumelela, amathegi afanayo asetshenziswa abathengisi ukulandelela i-inventory angase afundeke yinoma ubani onefoni.

 

 

Iningi lamathegi e-RFID ezitolo i-UHF engenzi lutho. Abanalo ibhethri. Lapho umfundi ethumela amaza omsakazo, ithegi idonsa amandla anele ukuze inike amandla i-chip yayo futhi ibuyisele isignali equkethe inombolo yesibonakaliso. Ithegi ngokwayo ayenzi lutho. Umfundi wenza umsebenzi.

 

Ngaphansi kwezimo ezinhle ithegi ye-UHF yokwenziwa ingafundwa kumamitha ayi-10. Izimo ezinhle zisho umoya ovulekile, akukho nsimbi eduze, akukho uketshezi, umaki oqondiswe kahle uma uhlobene nothi lokufunda. Ukufakwa kwe-warehouse okunezifundi ezigxilile kanye{3}}nozinti ezizuzisa kakhulu ngezinye izikhathi zithola amamitha angu-12 noma angu-15. Imininingwane evela kubakhiqizi bamathegi ngokuvamile ithatha ukusetha okulungile okungekho ezindaweni zokugcina impahla.

 

Beka ithegi efanayo eshalofini lensimbi futhi ububanzi buyehla. Ibeke ebhodleleni lamanzi iphinde yehle. Insimbi ibonisa isignali. Amanzi awumunca. Ukuma kwethegi okuhlobene ne-antenna yomfundi nakho kunendaba. Umfundi onothi{5}}olugqamile udinga ukuthi umaka uqondaniswe ngendlela ethile. Izimpondo eziyisiyingi{7}}ezine-polarized zithethelela kakhulu kodwa zishiya ububanzi obuthile.

 

 

Omaka-emvamisa ephansi ku-125 kHz abafundeka ngamasentimitha angu-10 noma ngaphansi. Lokhu kungena emakhadini okufinyelela kanye nama-chips okulandelela izilwane. Amathegi-emvamisa ephezulu ku-13.56 MHz afinyelela cishe imitha. Amakhadi okukhokha asebenzisa leli bhande. Ububanzi obufushane buyisici. Ucofa ikhadi kutheminali. Awuyizuzisi usuka ngaphesheya kwegumbi.

 

Omaka abasebenzayo bahlukile. Anamabhethri. Bayasakaza. Basebenza ngamamitha angama-30, amamitha angama-50, amamitha ayi-100 kuye ngokusetha. Amanye amasistimu wezimboni afunda amathegi asebenzayo kumamitha angamakhulu ambalwa. Ibhethri lengeza izindleko nosayizi. Ekugcineni iyafa. Kodwa ekulandeleleni iziqukathi zokuthutha noma izimoto egcekeni, i-passive range akwanele.

 

Umbuzo wefoni umayelana ne-UHF engenzi lutho. Ifoni ayikwazi ukulingana nezinti ezinkulu ezisetshenziswa abafundi be-warehouse. Imithethonqubo ikhawulela ukuthi mangakanani amandla aphathwa ngesandla angasakaza. U-Thomas Brunner e-Kathrein Solutions olinganisela ukuthi abafundi abasekelwe ocingweni{3}bezofika ku-120 centimeters best. Lokho kuseduze ngokuthepha ikhadi lokukhokha kunokuskena uhlu lwamagama esitolo sonke.

 

 

U-Katherine Albrecht uchithe iminyaka exwayisa nge-RFID. Uneziqu zobudokotela azithola eHarvard. Wasungula iqembu labathengi elibizwa nge-CASPIAN ngo-1999. Wabhala incwadi ngo-2005 ebiza amathegi e-RFID "ama-spychips." Le ncwadi icaphune ukufakwa kwelungelo lobunikazi kwe-IBM ne-BellSouth echaza izindlela zokulandelela abantu ngamathegi ezimpahleni zabo nakudoti. Abantu basembonini bathi wenza ihaba. Uthe bahlela ukugadwa ngobuningi. Ingxabano ayizange ixazululwe ngempela. Amathegi angena emikhiqizweni noma kunjalo.

 

Umbuzo wobumfihlo uncike ngokwengxenye ebangeni. Umaka ofundeka ngamasentimitha amabili kunzima ukuwuskena ngokuyimfihlo. Ithegi efundeka kumamitha ayi-10 kulula. Ifoni efunda imitha iphakathi nendawo. Ukuthi lokho kubalulekile kuncike ekutheni imaki inaluphi ulwazi nokuthi lufunwa ngubani.
