saib xyuas lub sijhawm
Kev saib xyuas ntawm cov dej hauv lub sijhawm ntawm txoj kev qis qis, underpasses thiab tunnels, thiab kis tau mus rau lub nroog qhov chaw saib xyuas dej thiab ceeb toom ntawm 4G wireless network.
Tshaj-limit tswb
Thaum cov dej theem siab dhau los lossis cov khoom siv tsis zoo, lub platform platform yuav cia li ceeb toom, thiab cia li xa cov lus ceeb toom rau lub xov tooj ntawm tes ntawm tus neeg saib xyuas.Lub koob yees duab txav mus tas li ntes cov xwm txheej xwm txheej thiab xa rov qab mus rau qhov chaw hais kom ua.
Kev saib xyuas ntawm txoj kev qis qis
Lub kaw lus muaj daim ntawv qhia zaub mov muaj nuj nqi, uas tuaj yeem tso saib cov ntaub ntawv qhov chaw ntawm ntau qhov chaw qis qis los ntawm software platform.
Raws li lub hauv paus ntsiab lus uas ntsuas cov kua zoo li qub yog proportional rau qhov siab ntawm cov kua, cov nyhuv piezoresistive ntawm diffused silicon los yog ceramic rhiab ntsiab yog siv los hloov lub siab zoo li qub rau hauv cov teeb liab hluav taws xob.Tom qab kub them nyiaj thiab linearity kho.Hloov mus rau hauv 4-20mADC tus qauv teeb liab tam sim no tso zis.Lub sensor ib feem ntawm cov khoom tuaj yeem muab tso ncaj qha rau hauv cov kua, thiab cov khoom xa tawm tuaj yeem kho los ntawm flange lossis bracket, uas yog qhov yooj yim heev rau nruab thiab siv.
Cov kua theem transmitter xaiv nyob rau hauv cov kev daws teeb meem no koom tes nrog peb cov ntse wireless rooj vag kom paub cov ntaub ntawv tej thaj chaw deb kis los ntawm 4G kev sib txuas lus.Nws muaj qhov zoo ntawm qhov me me thiab yooj yim installation.Nws yog tshwj xeeb tshaj yog haum rau hydrology, hauv nroog waterlogging, nroog txoj kev, dej ntws thiab pas dej, thiab lwm yam. Cov sij hawm uas cov dej theem tsis sib txawv heev.
Lub sensor node nkag lub rooj vag yog lub rooj vag qib kev lag luam nrog lub network chaw nres nkoj thiab 4G tag nrho Netcom kev sib txuas lus chaw nres nkoj.Nws tuaj yeem hloov kho Modbus RTU raws tu qauv cov ntaub ntawv rau hauv MQTT raws tu qauv thiab xa mus rau cov ntaub ntawv chaw nyob deb, txhawb kev sau cov khoom siv digital input signals, Txhawb cov zis ntawm digital tswj cov cim.Lub sensor node nkag lub rooj vag muaj kev sib sau ua ke, kis tau tus mob, thiab tswj kev ua haujlwm, thiab sib koom ua ke kev hloov pauv raws tu qauv, uas tuaj yeem txo cov nqi khiav lag luam thiab kev saib xyuas ntawm ntau yam khoom siv, thiab kev ua haujlwm ruaj khov thiab txhim khu kev qha.
Lub wireless theem sensor yog ib qho ntse ua kua theem saib xyuas cov cuab yeej uas siv cov qauv tsim ua ke.Cov khoom siv tau txais kev tsim micro-power.Nws siv silicon piezoresistive kua theem sensor nrog stainless hlau cais membrane raws li cov kua theem teeb liab ntsuas lub ntsiab.Nws txais yuav high-precision AD Lub converter sau cov kua theem teeb liab, thiab paub txog qhov xoom taw tes thiab qhov kub thiab txias kev ua haujlwm ntawm cov kua qib hauv qhov kub thiab txias.
Lub wireless theem sensor muaj ib tug built-in ceev-hloov tau loj-muaj peev xwm ntev-lub neej lithium thionyl chloride roj teeb pob rau lub hwj chim mov.Nws yog qhov tsim nyog rau kev siv hauv thaj chaw lossis tsis muaj lub zog hluav taws xob, xws li cov dej nag thiab cov kav dej phwj hauv lub network ntsuas cov dej hauv nroog, kev saib xyuas cov dej hauv nroog, thiab kev cia Tank qib xyuas, kev saib xyuas qib pas dej, thiab lwm yam. Cov cuab yeej siv NB-IoT Txoj kev sib txuas lus los ntawm kev xa cov ntaub ntawv mus rau qhov dej zoo tswj xyuas qhov system software kom paub txog kev saib xyuas lub sijhawm tiag tiag, kev tsim lub tswb, kev txheeb xyuas kev txheeb xyuas thiab lwm yam dej num ntawm cov ntaub ntawv hauv tsev.
Lub manhole cover condition monitor yog ib yam khoom siv los saib xyuas lub manhole npog ntawm nroog manholes.Nws yog ntsia rau ntawm phab ntsa ntawm manhole npog.Thaum lub manhole npog hloov thiab inclines thiab mus txog qhov tshwm sim ntawm lub tswb teeb meem (lub neej ntawd tus nqi ntawm qhov qhib npog inclination tswb tus nqi yog 30 °, nws tuaj yeem teeb tsa rau lwm lub kaum ntse ntse).), lub manhole npog saib yuav ua rau lub tswb thiab lub tswb ceeb toom yuav raug xa mus rau qhov chaw saib xyuas los ntawm kev xa xov wireless, thiab lub chaw saib xyuas yuav txheeb xyuas cov ntaub ntawv thiab txiav txim lub tswb.
Cov khoom no siv NB-IoT kev sib txuas lus wireless.Nws siv roj teeb fais fab mov thiab muaj cov yam ntxwv ntawm kev yooj yim installation, lub neej ntev roj teeb, siab nrhiav kom raug, thiab kev ua haujlwm ruaj khov.
Kev saib xyuas ntawm cov dej hauv lub sijhawm tiag tiag hauv thaj chaw qis qis uas ua rau muaj dej nkag, thiab kev ceeb toom rau cov chaw uas muaj dej loj heev-nrhiav.Lub kaw lus siv lub ntsuas ntsuas qib ultrasonic los ntsuas cov dej theem, thiab uploads cov ntaub ntawv qib sau los ntawm ultrasonic qib ntsuas ntsuas tau nruab rau hauv lub nroog qis qis uas muaj dej nyab.Thaum twg cov dej qib siab tshaj qhov pib, nws tam sim ntawd xa tawm cov lus ceeb toom ceeb toom rau koj Lub Chaw Saib Xyuas Lub Luag Haujlwm Tseem Ceeb tau ntsuas, thiab lub kaw lus tseem yuav muab ntau qib ntawm lub tswb rau ntau theem ntawm cov kua theem.
Lub hauv paus tswj hwm muaj zog thiab cov neeg siv software tuaj yeem tswj hwm ntau txhiab tus neeg siv khoom hauv ntej.Cov neeg siv tuaj yeem nkag mus rau hauv cov neeg siv software los xauj cov duab ntawm cov ntsiab lus saib hauv online, saib xyuas seb lub koob yees duab pem hauv ntej txuas nrog thiab hloov cov kev txwv nyob deb;tsis muaj lwm yam hard disk video recorders yuav tsum khaws cia ncaj qha.Tej thaj chaw deb PC cia.
Lub kaw lus siv ntau qhov ntsuas huab cua los muab lub kaw lus nrog cov ntaub ntawv huab cua tiag tiag rau kev saib xyuas.Nyob rau tib lub sijhawm, raws li kev kwv yees los nag, keeb kwm kev paub thiab kev tshawb xyuas cov ntaub ntawv loj, nws tau ceeb toom kom txo qis cov kua dej ntawm tag nrho cov kav dej sib txuas thiab ua haujlwm los nag hnub.Cov ntaub ntawv huab cua yog xa mus rau lub ntse yeeb nkab network system los ntawm cov chaw taws teeb kis tau tus mob ntawm Internet ntawm Yam.Lub kaw lus paub txog kev saib xyuas ntawm ib puag ncig xws li dej nag, cua ceev, cua kev taw qhia, kub, thiab av noo ntawm qhov ntsuas ntsuas.Cov cuab yeej muaj kev ua haujlwm ruaj khov thiab kev tshawb pom qhov tseeb, uas tuaj yeem ua tau raws li kev soj ntsuam huab cua.Cov kev cai ua lag luam.Nws yog siv nyob rau hauv ntau lub teb xws li nroog meteorological thiab ib puag ncig saib xyuas, kev thauj mus los, tub rog, kev ua liaj ua teb, hav zoov, thiab hydrology.
