IOT yog hais txog lub sijhawm sau los ntawm txhua yam khoom lossis cov txheej txheem uas yuav tsum tau saib xyuas, sib txuas, thiab sib tham sib, nrog rau nws lub suab, lub teeb, cua sov, hluav taws xob, mechanics, chemistry, biology, qhov chaw thiab lwm yam ntaub ntawv xav tau los ntawm ntau yam ua tau. Kev nkag mus hauv network los ntawm ntau yam khoom siv thiab thev naus laus zis xws li cov ntaub ntawv sensors, xov tooj cua zaus txheeb xyuas thev naus laus zis, lub ntiaj teb tso qhov system, infrared sensors, laser scanners, thiab lwm yam. Kom paub txog kev sib txuas ntawm txhua yam thiab cov khoom, thiab ntawm cov khoom thiab tib neeg, thiab paub txog kev nkag siab zoo. , kev lees paub thiab kev tswj cov khoom thiab cov txheej txheem.Is Taws Nem ntawm Tej Yam yog cov ntaub ntawv xa tawm raws li Is Taws Nem, kev sib txuas lus ib txwm siv network, thiab lwm yam, uas ua rau txhua yam khoom siv lub cev zoo tib yam uas tuaj yeem hais tawm ntawm nws tus kheej los tsim ib lub network sib txuas.
Kev taw qhia txog cov qauv kev sib txuas lus hauv Is Taws Nem ntawm Yam Ntiaj Teb
Kev sib txuas lus thev naus laus zis ntawm Is Taws Nem ntawm Yam tuaj yeem muab faib ua luv luv thiab ntev kev deb raws li cov teeb liab kis tau tus mob.Lub tshuab xa tawm luv luv raws li cov thev naus laus zis tseem ceeb suav nrog Wi-Fi, ZigBee, Z-Wave, Xov, Bluetooth™, Wi-SUN, thiab lwm yam. Nws yog siv rau cov khoom siv txawb uas twb muaj lawm xws li xov tooj ntawm tes, ntsiav tshuaj thiab cov khoom siv hnav, los yog ntse tsev, ntse Hoobkas thiab ntse teeb pom kev zoo thiab lwm yam teb.Yav dhau los, thev naus laus zis kev sib txuas lus ntev yog 2G, 3G, 4G thiab lwm yam kev sib txuas lus hauv xov tooj.Txawm li cas los xij, vim muaj qhov sib txawv ntawm cov kev xav tau ntawm Internet ntawm Yam (iot), xws li cov bandwidth loj thiab qeeb qeeb, ntau daim ntawv thov iot muaj cov ntaub ntawv me me thiab kev ua siab ntev ntev, thiab tib lub sijhawm yuav tsum tau npog ntau dua lossis sib sib zog nqus. rau hauv av thiab lwm thaj chaw uas muaj kev tiv thaiv hnyav heev.Rau cov ntawv thov saum toj no, kev sib txuas lus thev naus laus zis nrog kev nyob deb thiab kev siv hluav taws xob tsawg tau tsim, uas yog hu ua Low Power Wide Area Network (LPWAN), thiab NB-IoT yog lub ntsiab lus sib txuas lus thev naus laus zis rau cov neeg siv daim ntawv tso cai.Cov hauv qab no yog daim duab kos duab yooj yim ntawm Internet ntawm Yam system.
Short Range Wireless kev sib txuas lus Technology: Lub mais kawg ntawm Internet ntawm Yam ntiaj teb
Yog tias qhov kev xaiv tau ua raws li cov yam ntxwv ntawm kev sib txuas lus ntev wireless, kev sib txuas lus luv luv nrog microcontroller ua lub luag haujlwm tseem ceeb hauv lub davhlau ya nyob twg, tshwj xeeb tshaj yog nrog cov sensors los sau cov ntaub ntawv.
WIFI: Wireless LAN raws li IEEE 802.11 tus qauv, tuaj yeem suav tias yog qhov luv luv wireless txuas ntxiv ntawm wired LAN.Txhua yam koj xav tau teeb tsa WIFI yog wireless AP lossis wireless router, thiab tus nqi qis.
Zigbee:yog raws li IEEE802.15.4 tus qauv ntawm kev ceev ceev, luv luv, tsawg zog noj, ob-txoj kev wireless kev sib txuas lus technology LAN kev sib txuas lus raws tu qauv, kuj hu ua ntshav muv raws tu qauv.Nta: Kaw ntau yam, tsis tshua muaj teeb meem, kev tsim tus kheej (kev teeb tsa tus kheej, kho tus kheej, thiab tswj tus kheej), kev siv hluav taws xob tsawg, thiab cov ntaub ntawv tsawg.ZigBee raws tu qauv tau muab faib ua lub cev txheej (PHY), media access Control layer (MAC), transport layer (TL), network layer (NWK), and application layer (APL) from below to top.Cov txheej txheem lub cev thiab cov txheej txheem kev nkag mus rau kev tshaj tawm ua raws li IEEE 802.15.4 tus qauv.Nws yog tsuas yog siv rau Sensor thiab Control daim ntaub ntawv.Nws tuaj yeem ua haujlwm hauv peb qhov zaus ntawm 2.4GHz (ntiaj teb nrov), 868MHz (Tebchaws Europe nrov) thiab 915MHz (Asmeskas nrov), nrog rau siab tshaj plaws kis tau tus mob ntawm 250kbit / s, 20kbit / s thiab 40kbit / s, ntsig txog.Ib qho taw tes kis tau tus mob nyob rau hauv thaj tsam ntawm 10-75m, ZigBee yog ib lub wireless cov ntaub ntawv kis tau tus mob network platform tsim los ntawm ib tug mus rau 65535 wireless cov ntaub ntawv kis tau tus mob modules, nyob rau hauv tag nrho cov network ntau yam, txhua ZigBee network cov ntaub ntawv kis tau tus mob module muaj peev xwm sib txuas lus nrog ib leeg, los ntawm lub standard 75m nrug rau unlimited expansion.ZigBee nodes muaj zog heev, nrog cov roj teeb uas kav ntev li ntawm rau lub hlis mus txog ob xyoos thiab txog li 10 xyoo hauv kev pw tsaug zog,
Z-Wave: Nws yog qhov luv luv wireless kev sib txuas lus thev naus laus zis raws li RF, tus nqi qis, kev siv hluav taws xob tsawg, kev ntseeg siab thiab tsim nyog rau kev sib txuas lus, uas yog coj los ntawm Zensys, lub tuam txhab Danish.Kev ua haujlwm zaus band yog 908.42MHz (USA) ~ 868.42MHz (Tebchaws Europe), thiab FSK (BFSK / GFSK) kev hloov kho hom tau txais.Cov ntaub ntawv kis tau tus nqi yog 9.6 kb rau 40kb / s, thiab qhov kev pab cuam zoo ntawm cov teeb liab yog 30m sab hauv tsev thiab ntau tshaj 100m sab nraum zoov, uas yog tsim rau cov ntawv nqaim broadband.Z-Wave siv dynamic routing technology.Txhua Z-Wave network muaj nws qhov chaw nyob network (HomeID).Qhov chaw nyob (NodeID) ntawm txhua qhov ntawm lub network yog muab los ntawm Tus Tswj Xyuas.Txhua lub network tuaj yeem tuav qhov siab tshaj plaws ntawm 232 nodes (Slaves), suav nrog cov tswj hwm.Zensys muab Dynamically Linked Library (DLL) rau Windows kev txhim kho thiab cov neeg tsim khoom ntawm API ua haujlwm hauv nws rau PC software tsim.Lub wireless network tsim los ntawm Z-Wave thev naus laus zis tuaj yeem tsis tsuas yog paub txog kev tswj cov chaw taws teeb ntawm cov khoom siv hauv tsev los ntawm cov khoom siv network, tab sis kuj tswj cov khoom siv hauv Z-Wave network los ntawm Is Taws Nem network.
