Whakauru Whakauru o ngā Tohu RFID UHF i Raro i ngā Kauwhata Matua Katoa

He mea nui noa iho ngā tohu UHF RFID i te whakahaere taonga hou me ngā mahi logistikihana, nā te āheinga o te kōrero maha nei me tō rātou ngenetanga ki te whakatūpato i ngā taiao e rerekē ana. Tētahi atu wāhanga nui o rātou hīkoi ko te mea kua oti pai ki te wehewehe i a rātou e piki ana i ngā mata ki runga i ngā rāwhiti e rerekē ana. Ko tēnei whakaaro ka whakamatau i te kanorau o te tohu UHF RFID i runga i ngā rāwhiti e maha ana, inaianei ko te pari, ko te karaponga, ko te kiri, me ngā rāwhiti e kore rawa ki te kawe i ngā waiwai, i roto i ngā whakariterite hangarau me ngā tuhinga whakamahi.

1. Ngā rāwhiti pari
He mea whakatau te kaiwhakaako i runga i ngā tohu RFID ki ngā mata kiore rānei, nā te āheinga o te whakapūngao electromagnet. Kātahi ka tae he whakamātau i te UHF tag e hanga ana i tētahi hōtuhi matua hei whakatangata i te take o te mahi ki runga i te tai. Ko tana whiuwhiu wīra e tino whakaiti ana i te whakahokianga o te pūrongo me te whakawhitinga, ēngari ka whai ake ia i ngā roanga pānui tūpato e tuhi atu ana ki te 9 mete ki runga i ngā taonga kiore, pērā i ngā whakahaere ā-motu rānei, heoi anō ka noho tonu i runga i te kiore. Ko te iti o te whakarite (noa iho, 56 mm × 50 mm × 9 mm) e tiaki ana i te itinga whenua, engari ka noho pono tonu i ngā taiao kino, pērā i ngā whakahaere motuhake i ngā wāhanga paihere rānei, he wā ka noho mōwaho i ngā tūranga ā-poro.

2. Ngā Pūtanga Plastic me ngā Polymer
Ki ngā tūmomo kore whakaputa hiko, pērā i te ABS, PVC, rānei te polikābonēte, ka whakaangiangia te kairere UHF i te wawe. Ki te kore he takutaku electromagnetic, ka taea e te tohu te hīkina i te roa rawa atu o 12 mete ki ngā taiao waenganui. Ko tōna hoahoa inlay nui, ka whakarite tonu ki ngā taha āwhiti o ngā tūmomo pākete, mā tēnā ka pai hei whakamahi mō te whakahaere pūtea rīhi, nō reira ka rapua te tohu ki runga i ngā whakapakanga mahi rānei, ki runga i ngā paleti. Ko tōna kasing i tohua IP67 ka tiakina mai i te huka me te wai, he mea nui mō ngā whakahaere karawa mō te ao marokura.

3. Ngā tūmomo Kiriware me te Porosetī
Nga taonga kura me nga taonga porihoriho, e kitea ana i te horopaki whakariterite rongo kararehe ranei, he mea hiranga nui na te hunga whenua dielectric ranei. Te whakarite impedance o te tohu UHF e tiaki i te itinga herehere iti nei, e whakamana ana i te pono tirohanga nui ki runga i nga paeneke kura ranei me nga tapa porihoriho. Nga putanga matatika e whakaatu ana i te maha o te tawaroa tirohanga i waenganui i te 15% i runga i nga kawa motuwhenua, e whakaatu ana i tona pono i roto i nga wāhi pērā i te whakahaere i nga moenga rangahau ranei, me te whakahaere i nga whakapakoko taonga whare taonga.

4. Nga Kauwhata e ngaro ana i te Wai
Nō te mea e whakarerekē ana ngā wāhi karu mōhīhī ki ngā pūnaha RFID, tērā i te mea he nui te hiranga kawe o te wai. Ko te tohu e tārahitia nei ka whakahau ai tēnei i raro i tētahi hoahoa ā-rua, e whakaiti ana i te herekore ā-polarization, me te whakamana i te taunga pānuitanga i waenganui i 3–5 mete. He whaihua nui tēnei i roto i ngā mahi logistikihana o te kaiwhakatetonga, nō reira me te uruwhenua o te tohu i runga i ngā momo kōwhatu e whakaritorito ana i te wāhi, ā, me te whakahaere i ngā porihitanga wehewehe whakamuri hoki.

5. Ngā Pūnui Hāpai me ngā Rākau Whatu
Mō ngā matera o matatū (pērā i te karbona whariki) rānei, ko te hanganga kino iti, he wāhi iti noa (ki te iti rawa i te 0.3 mm uru) hei whakamutu i te whānuitanga o te matera i te waehere. Ko tana pū kawehe hei whakatinanatia i te hononga ki ngā matawhāiti me ngā matawhānui, pērā i te whariki rānei, ā, e whakaaetanga ana ki ngā whakahaere motokā rānei, me te whakahaere taonga kai paaka. Ka tae muri te whakamatakitaki i te kawe huarahi, kaore i te 20% o te whakaiti i ngā matera whakapiri paihere, hei whakamana i te kawe haere raraunga i roto i ngā horopaki tuku take.

Whakamutunga
Ko te hunga UHF RFID te whakapono i runga i ngā matawhāwhā o ngā matera, nā tana takotoranga atamai o te āniwaniwa me te whakapakari i te whakawhitiwhiti. Ki te whakatika i te whakapakari i te huinga ētita rāpori me te whakapakari i te ara matua, ka taea te mahi pai i roto i ngā whenua e huringa nei mai i te hanga hirahira ki te ritenga. Mō ngā putanga tuarua, ka taea te whakamahi i te itiiti ake tonu, ahakoa te whakapakari rānei i te pūmanawa me te whakaae ki ngā matera, hei whakamana i tana tikanga i roto i te ao IoT e huri nei.
