RFID Matagi Anogona Kuverengerwa Kusvika Papi?

 

Passive tags anoshanda panzvimbo pfupi. Active ma tag anoshanda kure zvakanyanya. Iwo chaiwo manhamba anoenderana nemidziyo, frequency, uye chii chiri pakati petegi nemuverengi.

 

Mhinduro ine basa izvozvi nekuti Qualcomm yakati gore rapfuura ichaisa vaverengi veUHF RFID mumachipi efoni. Zebra akatumira nhare yebhizinesi ine-yakaverengerwa mukuverenga muna Ndira. Iyo RAIN Alliance yakazivisa smartphone yakajairwa chirongwa munaKurume. Kana kuedza uku kukabudirira, iwo ma tag mamwe anoshandiswa nevatengesi kuteedzera hesita inogona kuverengwa nemunhu wese ane foni.

 

 

Mazhinji eRFID ma tag muzvitoro anongoita UHF. Havana bhatiri. Kana muverengi anotumira masaisai eredhiyo, iyo tegi inotora simba rakakwana kuti igone chip yayo uye kudzosera kumashure chiratidzo chine nhamba yekuzivikanwa. Iyo tag pachayo haiite chero chinhu. Muverengi anoita basa.

 

Mumamiriro ezvinhu akanaka iyo UHF passive tag inogona kuverengwa pamamita gumi. Mamiriro akanaka anoreva mhepo yakavhurika, hapana simbi padyo, hapana zvinwiwa, iyo teki yakanamirwa nemazvo inoenderana nemuverengi antenna. Kumisikidzwa kwewarehouse kuine zviverengero zvakamisikidzwa uye-maantenna akakwira dzimwe nguva anowana 12 kana 15 metres. Zvinotsanangurwa kubva kune vagadziri vema tag vanowanzo fungidzira akanakisa setups asipo mumatura chaiwo.

 

Isai tag imwechete pasherufu yesimbi uye huwandu hunodonha. Isa pabhodhoro remvura uye inodonha mberi. Simbi inoratidza chiratidzo. Mvura inoitora. Tag yekutarisa kune muverengi antenna zvine basa zvakare. Muverengi ane linear-polarized antenna inoda kuti tag ienderane neimwe nzira. Circular-polarized antennas anonyanya kuregerera asi anosiya mamwe maitiro.

 

 

Yakaderera-matagi e125 kHz akaverengwa ari masendimita gumi kana pasi. Aya anoenda mumakadhi ekuwana uye machipisi ekuronda mhuka. High-frequency tags pa13.56 MHz inosvika mita imwe chete. Makadhi ekubhadhara anoshandisa bhendi iri. The pfupi renji chinhu. Iwe unobaya kadhi pane terminal. Iwe hauizunguzire kubva mhiri kwekamuri.

 

Active tags akasiyana. Vane mabhatiri. Vanotepfenyura. Vanoshanda pa 30 metres, 50 metres, 100 metres zvichienderana nekuseta. Mamwe maindasitiri masisitimu anoverenga ma tag anoshanda pamazana emazana emamita. Bhatiri rinowedzera mutengo uye saizi. Pakupedzisira inofa. Asi pakuronda midziyo yekutakura kana mota mhiri kweyadhi, passive range haina kukwana.

 

Mubvunzo wefoni ndewekungoita UHF. Foni haikwanise kukwana maantenna makuru anoshandiswa nevaverengi veimba yekuchengetera zvinhu. Mitemo inoganhura simba rakawanda sei rinobatwa neruoko rinogona kutepfenyura. Thomas Brunner ari kuKathrein Solutions anofungidzira kuti foni{{3}vaverengi vanoverenga vangasvika 120 centimeters zvakanakisa. Zviri padyo nekubaya kadhi rekubhadhara pane kuongorora zvinhu kubva muchitoro.

 

 

Katherine Albrecht akapedza makore achiyambira nezveRFID. Ane doctorate kubva kuHarvard. Akavamba boka revatengi rinonzi CASPIAN muna 1999. Akanyora bhuku muna 2005 achidana RFID tags "spychips." Iri bhuku rakadoma IBM neBellSouth patent mafiling anotsanangura nzira dzekutevera vanhu kuburikidza nemategi muzvipfeko zvavo nemarara. Vanhu vemuindasitiri vakati akawedzera. Akataura kuti vari kuronga kutariswa kwevanhu vakawanda. Nharo dzacho hadzina kuzombonyatsogadziriswa. Iwo ma tags akapinda mune zvigadzirwa zvakadaro.

 

Mubvunzo wekuvanzika unotsamira pachikamu. Tag inoverengwa in two centimeters inonetsa kuscan pachivande. Tag inoverengwa pamamita gumi iri nyore. Foni inoverenga pamamita pane imwe nzvimbo pakati. Kuti izvo zvine basa zvinoenderana neruzivo rwupi iyo tag ine uye ndiani anoida.
