Qhov zoo ntawm GPRS Remote Power Meter Reading
Qhov zoo ntawm GPRS tej thaj chaw deb fais fab meter nyeem ntawv:
Tam sim no, muaj ntau yam thev naus laus zis rau kev nyeem ntawv ntsuas hauv Suav teb. Xws li kev nyeem ntawv phau ntawv ntsuas, RS485, infrared thiab fais fab kab cab kuj, thiab lwm yam. Ntawm lawv, cov thev naus laus zis ntawm RS485 thiab infrared meter nyeem ntawv yog cov paub tab thiab siv dav. Lub hwj chim kab cab kuj 'meter' nyeem tau tsuas yog siv nyob rau hauv ib cheeb tsam me me.
RS485 meter nyeem ntawv yuav tsum tau xaim thiab tsuas yog siv tau hauv thaj chaw me me (tsawg dua 1000 meters); infrared meter nyeem ntawv yuav tsum tau nyeem phau ntawv ntawm qhov chaw ntsuas; vim muaj kev cuam tshuam ntawm thev naus laus zis thiab lub hom phiaj ntawm cov phiaj xwm hluav taws xob hauv tsev, tseem muaj ntau yam teeb meem kev siv hluav taws xob hauv cov khoom siv hluav taws xob 'meter' nyeem ntawv.
Tam sim no, lub ntsuas ntsuas tsis siv neeg nyeem ntawv raws li GSM / GPRS / CDMA pej xeem network platform tau dhau los ua qhov tseem ceeb ntawm kev lag luam nyeem ntawv. Nws tsis tsuas yog daws tau qhov tsis txaus ntawm cov lus hais saum toj no-hais txog kev nyeem ntawv 'meter', tab sis kuj tau txais txiaj ntsig zoo rau cov neeg siv ntau los ntawm kev ruaj ntseg network zoo thiab cov nqi khiav lag luam tsawg. Yog li hais tias kev tsim cov meter nyeem ntawv tsis xav tau cov cuab yeej kim thiab tsis txwv los ntawm qhov chaw.
Kev ntsuas raws sij hawm thiab raug ntawm hluav taws xob hluav taws xob ncaj qha cuam tshuam rau kev lag luam kev lag luam ntawm kev tsim khoom thiab kev ua haujlwm. Lub ntsuas hluav taws xob tsis siv neeg nyeem ntawv raws li GSM / GPRS / CDMA pej xeem network platform txuag cov neeg siv khoom siv network kim thiab cov nqi kho. Thiab tsis muaj ib ntus thiab kev txwv hauv cheeb tsam, yog tias muaj cov kab ke hauv zos nrog lub xov tooj ntawm tes, nws tuaj yeem ua haujlwm ruaj khov. Ntawm lawv, GSM cov lus luv luv wireless meter nyeem ntawv muaj cov nqi ua haujlwm qis, uas tseem txhim kho qhov siv tau ntawm lub kaw lus. Lub 'meter' davhlau ya nyob twg tuaj yeem ua haujlwm tshaj tawm cov ntaub ntawv ntsuas raws li lub sijhawm teem tseg, thiab lub ntsuas ntsuas ntsuas tuaj yeem nyeem tus nqi ntawm ib lub 'meter' txhua lub sijhawm. Thiab cov ntaub ntawv tau cia li khaws cia hauv cov ntaub ntawv, uas yooj yim rau tus neeg teb xov tooj nug tom qab. Lub kaw lus tuaj yeem tsim cov ntawv ceeb toom txhua hnub, cov ntawv tshaj tawm txhua hli, cov duab nkhaus, thiab lwm yam, uas yog qhov xav tau, raug, thiab ua haujlwm tau zoo.
