Raws li qhov kev thov rau IOT thev naus laus zis cov khoom lag luam los ntawm cov neeg siv khoom tshiab thiab qub hauv IOT daim ntawv thov scenarios tseem nce ntxiv, hauv kev teb rau cov kev xav tau ntawm kev lag luam thiab nrog kev sib koom tes ntawm DTECH thiab cov neeg koom tes, DTECH tau hloov kho tag nrho cov khoom siv wireless LORA rau IOT TPUNB thev naus laus zis. cov khoom.
TPUNB (Techphant Ultra-Narrow Band), raws li kev siv thev naus laus zis thev naus laus zis IOT kev sib txuas lus, ua rau IOT teb mus rau theem tshiab ntawm kev txhim kho nrog nws qhov tshwj xeeb kev zoo thiab cov yam ntxwv tshiab.
Hauv xyoo 2024,DTECH USB/RS232/485 rau TPUNB4km wireless cov ntaub ntawv xa xov tooj cua DTU tau tsim tawm tshiab.Nws yog siv los daws cov teeb meem ntawm kev sib kis qeeb qeeb, kev sib kis luv luv thiab tsawg tus lej ntawm kev sib kis bytes ntawm cov khoom qub LORA.
1. Vim li cas thiaj xaiv TPUNB IOT tshuab?
Cov thev naus laus zis no siv cov khoom siv hauv network xws li TPUNB hauv paus chaw nres tsheb, rooj vag, thiab cov qauv tsim kom muaj kev ruaj ntseg IOT ntiag tug network hauv ntau qhov xwm txheej uas siv ntau txoj hauv kev sib txuas kom ua tiav kev sib txuas ntawm lub zog siv hluav taws xob ntau rau ntau qhov kev nkag siab terminals hauv lub network. kev pab them nqi.Nws muaj cov yam ntxwv ntawm kev ruaj ntseg siab, tiv thaiv kev cuam tshuam muaj zog, ntau qhov sib txuam, tus nqi qis, thiab kev xa tawm yooj yim.Nws tuaj yeem siv dav hauv ntau qhov chaw xws licov nroog ntse, cov chaw ua si ntse, lub zog ntse, thiab kev lag luam Internet ntawm Yam.
2. Dab tsi yog DTECH USB/RS232/485 rau TPUNB 4km wireless cov ntaub ntawv xa xov tooj cua DTU?
1) 4000 meters ntev, tsis muaj kev sib kis
Kev nce siab, siab tau txais rhiab heev, thiab muaj zog heev ntawm phab ntsa nkag.Nyob rau tib qhov deb, piv nrog LORA cov khoom, nws tuaj yeem xa cov ntaub ntawv ntau dua thiab kev sib kis ceev dua.Nyob rau tib lub sijhawm, tus nqi ntawm cov ntaub ntawv yuav tsis poob pob ntawv, uas daws qhov teeb meem ntawm LORA cov ntaub ntawv me me rau kev sib kis mus ntev, qhov teeb meem ntawm pob ntawv poob.
2) Sib nrug deb, sib kis ntau, kis tau sai
Cov kev teeb tsa ib txwm tuaj yeem ua tsis tau tsuas yog ua tiav 4km kev sib txuas lus ib txwm, tab sis kuj ua kom 1280-byte cov ntaub ntawv xa mus (tsis muaj pob ntawv buffering) thiab huab cua tus nqi tuaj yeem ncav cuag 76.8kbps, uas tuaj yeem yooj yim tiv nrog qis-latency, high-concurrency thiab multi-scenario applications. .
3) Wireless parameter configuration, ntse adaptive self-synchronization
Tsis muaj kev txwv rau tus naj npawb ntawm cov terminals txuas nrog cov khoom.Qhov chaw nres nkoj RS485 tuaj yeem txuas rau 256 li thiab RS232 chaw nres nkoj tuaj yeem txuas rau 1 lub cuab yeej.RS485 thiab RS232 tuaj yeem xa cov ntaub ntawv tib lub sijhawm.Kev sib kis ntawm bidirectional siv cov kab ke sib kis tshuab los xyuas kom meej tias cov ntaub ntawv tsis poob pob ntawv.
4) Qhov muag tsis pom kev tsim qauv, tsis tas yuav tsum paub qhov txawv ntawm kev xa thiab txais qhov kawg
Cov khoom txhawb nqa point-to-point, point-to-multipoint, thiab multipoint-to-multipoint wireless transceiver functions.Nws tsis txwv qhov kawg yog lub transmitter lossis receiver.Nws yog qhov yooj yim heev rau cov neeg ua haujlwm tu thiab hloov tau yooj yim dua thiab siv dav.Nws yog dav siv nyob rau hauv debugging.
5) Kev siv ntau yam
① Kev ua liaj ua teb ntse:Kev saib xyuas lub sijhawm tiag tiag ntawm qhov kub thiab txias, av noo, lub teeb, av, pH, thiab lwm yam, txuag lub sijhawm thiab kev siv zog, thiab ua kom yooj yim rau kev tswj xyuas.
② Muaj kev tswj hwm:Tsis xav tau kev sib txuas lus, RS485/232 tuaj yeem hloov kho tau yooj yim wirelessly, txhim kho kev ua haujlwm thiab kev tswj xyuas yooj yim.
③ Intelligent meter nyeem ntawv:Tsis tas yuav tsum tau nyeem phau ntawv qhia kev ntsuas ntsuas, ntse sau cov dej, hluav taws xob thiab lwm yam ntaub ntawv los txhim kho kev ua haujlwm thiab pab tswj kev tswj hwm.
DTECH USB / RS232 / 485 rau TPUNB 4km wireless cov ntaub ntawv xa xov tooj cua DTU tau tsim tawm tshiab.Nws sau cov kev sib txawv hauv kev ua lag luam thiab muab cov ntaub ntawv sib kis tau yooj yim thiab yooj yim rau ntau yam lag luam.
