Papamuri me te Whakamahinga
He hangarau tautuhi aunoa te hangarau RFID e ahu mai ana i ngā tohu ahokore, ā, he pai mō ngā momo whakamahinga maha. Kei te piki haere te aro ki tēnei hangarau i roto i ngā whare pukapuka, ngā tuhinga me te whakahaere pūranga. Mā te tāpiri atu Ngā tapanga whare pukapuka RFID Ka taea te whakatinana i ngā mahi pēnei i te pānui aunoa, te uiui, te tiki me te whakahoki mai i ngā pukapuka, ngā tuhinga me ngā pūranga, ā, ka pai ake te whai huatanga o te whakahaere me te taumata ratonga o ngā rauemi tuhinga.
E rua ngā momo matua oNgā tohu RFID mō ngā pukapuka e whakamahia ana i roto i ngā whare pukapuka me te whakahaere tuhinga pūranga, ngā tapanga RFID HF me Ngā tapanga RFID UHFHe rerekē ngā āhuatanga o ēnei tapanga e rua. Tukua ahau kia tātari i ō rāua rerekētanga i raro nei:
Ka taea te wehewehe i te hangarau RFID ki ētahi momo e ai ki ngā auau mahi rerekē: te auau iti (LF), te auau teitei (HF), te auau tino teitei (UHF) me te ngaruiti (MW). I roto i ēnei, ko te auau teitei me te auau tino teitei ngā pukapuka e rua e whakamahia whānuitia ana mō ngā hangarau RFID i tēnei wā. He painga me he ngoikoretanga o ia o ia, ā, he rerekē te whakamahinga i roto i ngā horopaki rerekē.
Mātāpono mahi: Ko te hangarau RFID auau-teitei e whakamahi ana i te mātāpono o te hononga ā-papa tata, arā, ka tukuna e te kaipānui te pūngao me te whakawhiti raraunga ki te tohu mā te papa aukume. Ko te hangarau RFID UHF e whakamahi ana i te mātāpono o te irahiko hiko-papa tawhiti, arā, ka tukuna e te kaipānui te pūngao me te whakawhiti raraunga ki te tohu mā roto i ngā ngaru hiko-aukume.
Tātaritanga kōwhiringa hua
1. Maramara:E taunaki ana a HF kia whakamahia te maramara NXP ICODE SLIX, e tutuki ana i ngā kawa ISO15693 me te ISO/IEC 18000-3 Aratau 1. He nui te mahara EPC o tēnei, arā, 1024 moka, ā, ka taea te tuhi anō i ngā raraunga mō te 100,000 wā, ā, ka taea te penapena mō te neke atu i te 10 tau.
E taunaki ana te UHF kia whakamahia te NXP UCODE 8, Alien Higgs 4, e tutuki ana i ngā kawa ISO 18000-6C me te EPC C1 Gen2, EPC. He mahara kaiwhakamahi 128-moka tōna, ā, ka taea te tuhi anō i ngā raraunga mō te 100,000 wā, ā, ka tiakina mō te neke atu i te 10 tau.
2. Ngā Antenna: He angiangi ngā pūihi HF, ā, ka whakaiti i te pānga pokanoa o te whakarārangi tohu maha. Ka taea e ngā ngaru hikohiko te whakawhiti i ētahi pūngao ki ngā tohu i muri i a rātou mā te pūihi. He tino angiangi te āhua, he iti te utu, he tino pai te mahi, ā, he tino ngāwari ki te huna. Nō reira, he pai ngā tohu whare pukapuka RFID nfc atamai 13.56mhz mō te whakahaere pukapuka me ngā pouaka pūranga. Heoi, i roto i te whakahaere kōnae whārangi-kotahi, ka whakamahia te nuinga mō ngā kōnae tino muna, pērā i ngā tuhinga tino ngaro, ngā kōnae kaimahi nui, ngā tuhi hoahoa, me ngā tuhinga muna. Kotahi, torutoru rānei ngā whārangi i roto i ēnei putea. Mā te whakamahi i ngā tapanga whare pukapuka RFID HF 13.56mhz ka taupatupatu tata, ka puta he pokanoa tetahi ki tetahi, ka pā ki te tika o te mōhiotanga, ā, ka kore e tutuki i ngā whakaritenga whakahaere. I tēnei wā, e taunakihia ana kia whakamahia te otinga tohu UHF.
3. Rauemi mata: Ka taea e te HF me te UHF te whakamahi i te pepa toi hei rauemi mata, ā, ka taea hoki te tā i ngā tuhinga ritenga, ngā tauira, ngā waehere pae rānei. Ki te kore koe e hiahia ki te tā, ka taea e koe te whakamahi i te tānga maku tika.
4. Piripiri: Ko te whakamahinga o ngā tohu he mea whakapiri ki te pepa. He ngāwari ki te whakapiri, ā, kāore i te uaua te taiao whakamahinga. I te nuinga o te wā ka taea te whakamahi i te piripiri rewa wera iti te utu, te piripiri wai rānei.
5. Pepa tuku: Ko te tikanga, ka whakamahia he pepa kei muri he karāhe me te paparanga hinu silicone, he pepa kāore e piri, ā, he māmā noa iho te haehae i te tohu.
6. Te whānuitanga o te pānui: Ko te hangarau HF RFID he hangarau hononga ā-papa tata, ā, he iti te whānuitanga mahi, ko te tikanga kei roto i te 10 henimita. Ko te hangarau UHF RFID he hangarau irahiko hiko papa tawhiti. He nui te urunga o te ngaru hiko, ā, he nui te whānuitanga mahi, ko te tikanga neke atu i te 1 mita. He iti te tawhiti pānui o te HF, nō reira ka taea te kimi tika i ngā pukapuka, i ngā kōnae pūranga rānei.
7. Te tere o te pānui: Nā te herenga o te kaupapa hononga ā-papa tata, he puhoi te tere pānui o te hangarau HF RFID, ā, he uaua ki te pānui i ngā tohu maha i te wā kotahi. Nā ngā painga o te kaupapa irahiko hiko-papa tawhiti, he tere ake te pānui a te hangarau UHF RFID, ā, he mahi pānui rōpū anō hoki. He roa ake te tawhiti pānui a te hangarau UHF, ā, he tere ake te tere pānui, nō reira ka pai ake te whai hua i te wā e pupuri pukapuka ana, e pupuri kōnae ana rānei.
8. Te kaha ārai-whakararuraru: Mā te hononga tata-papa o te hangarau RFID auau-teitei ka whakaitihia te wawaotanga ahokore pea, ka tino "ātete" te hangarau auau-teitei ki te haruru taiao me te wawaotanga hikohiko (EMI), nō reira he kaha tōna kaha ki te ārai i te wawaotanga. Ka whakamahia e te UHF te kaupapa tuku hikohiko, nō reira he ngawari ake ki te wawaotanga hikohiko. I taua wā anō, ka whakaatahia e te konganuku ngā tohu, ā, ka taea e te wai te mimiti i ngā tohu. Ka wawao ēnei āhuatanga i te mahi noa o te Tapanga UHF RFIDAhakoa ētahiNgā tohu RFID UHF kore mahi Whai muri i te pai o te mahi a ngā hangarau ki te ārai i te pokanoa mai i ngā konganuku me ngā wai, ki te whakaritea ki ngā tapanga auau teitei, he iti tonu te ngoikore o te UHF, ā, me whakamahi ētahi atu tikanga hei whakakapi.
9. Te kaha ārai-tahae: Te whakamahinga ongā tapanga ārai-tahae haumarutanga RFID whare pukapukaI te taha o ngā hongere me ngā pūnaha āhua-tatau, ka taea te ārai i ngā pukapuka me ngā kōnae kei ngaro, ā, ka whakatinanahia hoki ngā mahi whakaoho tango ture kore.He painga me he ngoikoretanga ō ia otinga HF me te UHF RFID, ā, me paunatia, me whakataurite hoki te kōwhiringa i runga i ngā hiahia me ngā āhuatanga motuhake.
