Txoj cai ua haujlwm thiab kev ua tau zoo ntawm RFID thev naus laus zis hauv qhov chaw ib puag ncig hnyav

Kev siv tshuab Radio Frequency Identification (RFID) yog ib feem ntawm txheej kev pom hauv Internet of Things. Txheej kev pom yog txheej qis tshaj plaws hauv Internet of Things architecture, uas yog lub luag haujlwm tseem ceeb rau kev sau thiab kev pom cov ntaub ntawv. Nws sau, hloov pauv thiab xa cov ntaub ntawv los ntawm lub ntiaj teb mus rau Internet of Things platform los ntawm ntau yam sensors thiab cov khoom siv pom. Raws li ib qho tseem ceeb ntawm kev siv tshuab sensing, RFID txiav txim siab cov khoom thiab tau txais cov ntaub ntawv tseem ceeb los ntawm cov teeb liab wireless radio frequency yam tsis muaj kev cuam tshuam ntawm tib neeg, thiab tuaj yeem ua haujlwm hauv ntau qhov chaw nyuaj. Yog li ntawd, RFID technology yog ib feem tseem ceeb ntawm txheej kev pom ntawm Internet of Things.

1. Kev siv tshwj xeeb ntawm kev txheeb xyuas zaus xov tooj cua (RFID) thev naus laus zis hauv txheej kev pom ntawm Internet of Things

Cov ntaub ntawv thov tshwj xeeb ntawm kev siv tshuab xov tooj cua zaus txheeb xyuas (RFID) hauv txheej kev pom ntawm Is Taws Nem ntawm Yam muaj ntau qhov chaw, thiab nws siv dav thiab tseem ceeb hauv Is Taws Nem ntawm Yam.

Kev tswj hwm logistics: RFID thev naus laus zis tau siv dav hauv kev tswj hwm logistics. Piv txwv li, hauv Tshav Dav Hlau Aviation Logistics Park, Sinotrans Air Transport Development Company siv cov khoom siv RFID los faib cov khoom sai sai, txhim kho qhov ua tau zoo ntawm kev ua haujlwm logistics. Tsis tas li ntawd, RFID thev naus laus zis kuj tseem siv los saib xyuas thiab tswj kev thauj mus los, kev khaws cia, kev thauj khoom thiab kev tshem tawm cov khoom hauv lub sijhawm tiag tiag kom ntseeg tau tias muaj kev ua haujlwm zoo thiab pob tshab ntawm cov txheej txheem logistics.

Kev tswj cov cuab yeej ntse: RFID thev naus laus zis tuaj yeem siv rau kev tswj cov cuab yeej ntse, uas tuaj yeem txheeb xyuas thiab taug qab cov cuab yeej los ntawm lub tshuab txheeb xyuas zaus xov tooj cua, yog li txhim kho kev tswj hwm zoo thiab raug.

Lub txee khoom siv kho mob ntse: Hauv kev kho mob, RFID thev naus laus zis siv rau cov txee khoom siv kho mob ntse, uas tuaj yeem txheeb xyuas thiab taug qab cov khoom siv kho mob los ntawm cov cim npe kom ntseeg tau tias kev siv thiab kev tswj hwm cov khoom siv.

Cov khw muag khoom ntse thiab cov txee muag khoom tsis muaj neeg tsav: RFID thev naus laus zis kuj tseem siv rau hauv cov khw muag khoom ntse thiab cov txee muag khoom tsis muaj neeg tsav, uas tuaj yeem txheeb xyuas cov khoom uas cov neeg siv khoom yuav los ntawm RFID cov cim npe muag khoom kom ua tiav kev them nqi tus kheej thiab kev tswj cov khoom muag.

Kev saib xyuas kev nyab xeeb ntawm qhov chaw nres tsheb npav: RFID thev naus laus zis kuj tseem siv rau hauv kev saib xyuas kev nyab xeeb ntawm qhov chaw nres tsheb npav, ua ke lub kaw lus tswj kev nkag thiab tawm ntawm lub tsheb thiab lub kaw lus saib xyuas video ntse ntawm chaw nres tsheb kom txhim kho kev nyab xeeb thiab kev tswj hwm zoo ntawm qhov chaw nres tsheb.

Kev Lag Luam Hauv Is Taws Nem ntawm Yam Khoom thiab Cov Txheej Txheem Kev Thauj Mus Los Txawj Ntse: Hauv Kev Lag Luam Hauv Is Taws Nem ntawm Yam Khoom thiab Cov Txheej Txheem Kev Thauj Mus Los Txawj Ntse, RFID thev naus laus zis siv los daws teeb meem kev nyeem-sau thiab teeb meem sau cov ntaub ntawv, thiab txhim kho kev nyeem-sau kom zoo thiab raug. Piv txwv li, "Internet Bicycle" routing protocol raws li Delay Tolerant Network (DTN) siv los sau cov ntaub ntawv hauv lub sensor network ntawm lub kaw lus sib koom tsheb kauj vab pej xeem.

2. Kev sib cuam tshuam ntawm txheej kev pom thiab lwm cov txheej hauv IoT architecture

Hauv IoT architecture, kev sib cuam tshuam ntawm cov txheej txheem pom thiab lwm cov txheej txheem (xws li cov txheej txheem network thiab cov txheej txheem thov) yog raws li nram no:

Cov txheej txheem pom tau sau cov ntaub ntawv los ntawm lub ntiaj teb tiag tiag, xws li kub, av noo, lub teeb, suab, qhov chaw, video, thiab lwm yam, los ntawm ntau yam sensors thiab cov khoom siv tau txais cov ntaub ntawv. Tom qab cov ntaub ntawv raug hloov mus rau hauv hom ntawv cov ntaub ntawv tus qauv, nws raug ua tiav los ntawm lub kaw lus embedded thiab xa mus rau cov chaw nres tsheb hauv paus thiab cov rooj vag nkag ntawm cov txheej nkag los ntawm lub network sib txuas lus wireless, thiab thaum kawg mus txog lub davhlau ya nyob twg ntawm tus neeg siv. Cov txheej txheem network nyob nruab nrab ntawm cov txheej pom thiab cov txheej thov, thiab yog lub luag haujlwm rau kev xa cov ntaub ntawv cov ntaub ntawv sau los ntawm cov txheej pom mus rau cov txheej thov rau kev tshuaj xyuas thiab kev tswj hwm. Cov txheej txheem network feem ntau suav nrog peb ntu: lub network sib sau ua ke, lub network nkag mus, thiab lub network nqa khoom. Lub network sib sau ua ke siv cov thev naus laus zis sib txuas lus wireless (xws li TPUNB, LoRa, ZigBee, Bluetooth, Wi-Fi, thiab lwm yam) kom paub txog kev sib sau ua ke ntawm cov ntaub ntawv pom ntau yam; lub network nkag mus siv 6LoWPAN thiab M2M architecture kom paub txog kev nkag mus ntawm cov ntaub ntawv pom los ntawm lub network sib sau ua ke mus rau lub network nqa khoom; lub network nqa khoom siv IPv6 thiab M2M thev naus laus zis los ua kom tau raws li qhov xav tau ntawm ntau qhov chaw nyob thiab paub txog kev sib txuas ntse ntawm cov tshuab thiab cov khoom siv.

Cov txheej txheem thov yog txheej sab saum toj ntawm IoT architecture thiab yog lub luag haujlwm rau kev hloov cov ntaub ntawv ua tiav rau hauv cov ntawv thov tiag tiag. Cov txheej txheem pom kev cuam tshuam nrog cov txheej txheem platform los ntawm kev sib txuas thiab xa cov ntaub ntawv los ntawm cov txheej txheem pom mus rau cov txheej txheem platform rau kev ua tiav. Tib lub sijhawm, lub module kuj tseem yuav tsum ua cov lus qhia los ntawm cov txheej txheem thov, hloov cov lus qhia mus rau hauv cov lus qhia ua haujlwm tshwj xeeb thiab xa lawv mus rau cov txheej txheem pom. Cov txheej txheem thov feem ntau ua tiav kev tswj hwm cov ntaub ntawv thiab kev ua cov ntaub ntawv, thiab muab cov ntaub ntawv no nrog cov ntawv thov kev lag luam. Hauv qhov project tsim kho tshuab kho mob ntse, cov txheej txheem thov sau, tshuaj xyuas thiab ua cov ntaub ntawv los ntawm ntau qhov xwm txheej hauv tsev kho mob kom ua tiav kev pom kev sib koom ua ke thiab kev sib txuas ntawm IoT nodes thiab cov khoom siv hauv tsev kho mob.

3. Txoj cai ua haujlwm thiab kev ua tau zoo ntawm RFIDthev naus laus zis hauv cov chaw ib puag ncig hnyav

Lub hauv paus ntsiab lus ua haujlwm thiab kev ua tau zoo ntawm RFID thev naus laus zis hauv qhov chaw ib puag ncig hnyav tuaj yeem tshuaj xyuas los ntawm ntau yam.

Lub hauv paus ntawm RFID thev naus laus zis nyob rau hauv nws txoj kev txheeb xyuas tsis sib cuag. Thaum lub Cov cim npe RFID rau kev lag luam Nkag mus rau hauv thaj chaw RF ntawm tus nyeem ntawv, lub kav hlau txais xov tau txais lub teeb liab RF uas tus nyeem ntawv tso tawm, tsim cov hluav taws xob induced, ua kom lub nti hauv daim ntawv cim npe ua haujlwm, thiab yog li ntawd paub txog kev nyeem cov ntaub ntawv.
