LoRa Wireless Meter Reading Solution

I. System Overview

CovHAC-ML (LoRa)'meter' nyeem ntawv system yog ib qho kev daws teeb meem tag nrho raws li LoRa thev naus laus zis rau kev siv hluav taws xob qis ntse ntse nyeem ntawv. Cov kev daws teeb meem suav nrog lub ntsuas ntsuas kev tswj hwm lub platform, lub tshuab ua kom pom tseeb, qhov ze-kawg saib xyuas tuav RHU thiab ntsuas ntsuas ntsuas ntsuas.

Lub kaw lus ua haujlwm suav nrog kev nrhiav tau thiab kev 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-ML (LoRa)wireless tej thaj chaw deb ntsuas kev nyeem ntawv muaj xws li: wireless meter nyeem module HAC-ML, Concentrator HAC-GW-L, handheld davhlau ya nyob twg HAC-RHU-L, iHAC-ML meter nyeem ntawv them nyiaj system (WEB server).

● CovHAC-MLlow-power wireless meter nyeem module: Xa cov ntaub ntawv ib hnub ib zaug, nws koom ua ke tau txais, ntsuas thiab tswj valve hauv ib qho module.

● HAC-GW-L Concentrator: Txhawb txog 5000pcs meters, khaws 5000 uplink cov ntaub ntawv thiab nug cov ntaub ntawv khaws tseg los ntawm Server.

● HAC-RHU-L handheld davhlau ya nyob twg: Teem tsis xws li 'meter' ID thiab pib nyeem ntawv thiab lwm yam, teem lub hwj chim ntawm lub HAC-GW-L concentrator wirelessly, siv rau mobile handheld meter nyeem ntawv.

● Lub iHAC-ML 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-ntev nrug: Nroog cheeb tsam: 3-5km, nyob deb nroog: 10-15km

Ultra-tsawg zog noj: Lub ntsuas ntsuas ntsuas tau txais lub roj teeb ER18505, thiab nws tuaj yeem ncav cuag 10 xyoo.

Muaj peev xwm tiv thaiv kev cuam tshuam: Txais TDMA thev naus laus zis, cia li synchronize lub sijhawm sib txuas lus kom tsis txhob muaj cov ntaub ntawv sib tsoo.

Muaj peev xwm loj: Tus Concetrator tuaj yeem tswj tau txog li 5,000 meters thiab txuag 5000 cov ntaub ntawv khiav.

Kev ua tau zoo ntawm kev nyeem ntawv 'meter': ntau tus tub ntxhais RF tsim ntawm Concentrator tuaj yeem tau txais cov ntaub ntawv ib txhij ntawm ntau zaus thiab ntau tus nqi.
