Kev daws teeb meem

NB-IoT/LTE Cat1 Wireless Meter Reading Solution

I. System Overview

CovHAC-NBh (NB-IoT)'meter' nyeem ntawv yog ib qho kev daws teeb meem tag nrho raws li qhov siv hluav taws xob tsawg hauv cheeb tsam network thev naus laus zis ntawm Is Taws Nem ntawm Yam rau cov cuab yeej siv hluav taws xob qis ntse ntse nyeem ntawv.Cov kev daws teeb meem suav nrog lub ntsuas ntsuas kev tswj hwm lub platform, qhov ze-kawg kev saib xyuas tuav RHU thiab lub davhlau ya nyob twg kev sib txuas lus module.Lub kaw lus ua haujlwm suav nrog kev nrhiav tau thiab ntsuas, kev sib txuas lus ob txoj kev, ntsuas kev nyeem ntawv tswj valve thiab kev saib xyuas ze-kawg thiab lwm yam kom tau raws li cov kev xav tau ntawm cov chaw taws teeb nyeem ntawv.

II.Qhov System Cheebtsam

HAC-NBh (NB-IoT)wireless tej thaj chaw deb ntsuas kev nyeem ntawv muaj xws li: wireless meter nyeem module HAC-NBh, handheld davhlau ya nyob twg HAC-RHU-NB, iHAC-NB meter nyeem ntawv them nyiaj system (WEB server).

kev (1)

● Lub HAC-NBh low-power wireless meter nyeem module: Xa cov ntaub ntawv ib hnub ib zaug, txhawb kev qhia infrared lossis sib nqus cov lus qhia (yeem), thiab koom ua ke tau txais, ntsuas thiab tswj valve hauv ib qho module.

● HAC-RHU-NB handheld davhlau ya nyob twg: On-site NB teeb liab saib xyuas, ze-kawg tu rau cov khoom siv davhlau ya nyob twg, kev teeb tsa.

● Lub iHAC-NB meter nyeem ntawv them lub platform: tuaj yeem xa mus rau ntawm huab cua platform, lub platform muaj lub zog muaj zog, thiab cov ntaub ntawv loj tuaj yeem siv rau kev tsom xam.

IV.Cov yam ntxwv ntawm qhov system

● Ultra-tsawg zog noj: Lub peev xwm-hom ER26500 roj teeb tuaj yeem ncav cuag 8 xyoo.

● Kev nkag tau yooj yim: Tsis tas yuav rov tsim kho lub network, nws tuaj yeem siv ncaj qha rau kev lag luam siv nrog tus neeg teb xov tooj lub network uas twb muaj lawm;

● Muaj peev xwm loj: Khaws 10-xyoo cov ntaub ntawv khov txhua xyoo, 12-hli cov ntaub ntawv khov txhua hli, thiab 180-hnub cov ntaub ntawv khov txhua hnub.

● Ob txoj kev sib txuas lus: Ob txoj kev sib kis tau los ntawm cov chaw taws teeb thiab kev nyeem ntawv, nws kuj tseem tuaj yeem paub cov chaw taws teeb thiab cov lus nug tsis muaj, tswj li qub thiab lwm yam.

● Kev saib xyuas ze-kawg: Kev saib xyuas ze-kawg tuaj yeem ua tiav los ntawm cov cuab yeej infrared, suav nrog cov haujlwm tshwj xeeb xws li kev hloov kho firmware.

Ⅴ.Daim ntawv thov Scenario

Wireless meter nyeem dej ntsuas dej, ntsuas hluav taws xob, ntsuas roj, thiab ntsuas ntsuas kub.

Tsawg ntawm qhov chaw tsim khoom ntim, tus nqi qis thiab tus nqi siv tag nrho qis.
