Integrated Sts Prepaid Water Meter Digital Water Meter

Lub 'meter' txhawb nqa STS prepaid raws tu qauv. Tokens tuaj yeem raug xa mus rau STS meter los ntawm CIU, infrared unit, lossis meter keyboard kom paub txog kev them nyiaj ua ntej, hloov valve, thiab lwm yam haujlwm. Nyob rau tib lub sijhawm, lub concentrator txhawb LORA wireless tsis siv neeg kev sib txuas lus ntawm cov meters thaum nyeem ntawv. Networking muaj nuj nqi, theem network tuaj yeem nce mus txog qib 3, uas ua rau muaj txiaj ntsig zoo heev.

Lub ntsuas dej muaj cov yam ntxwv ntawm kev them nqi raug, kev siv yooj yim, thiab kev tswj xyuas kom zoo.

• Tus nqi dej ntaiv tuaj yeem teeb tsa (tsis pub tsawg dua 10 kauj ruam), tuaj yeem khaws 50 TIDs rau cov lus nug yooj yim,
• Cov ntaub ntawv dej txhua hli tuaj yeem khaws cia thiab sau tseg rau 10 xyoo, muaj cov dej so hnub so, nyiaj ntau dhau, tsis txaus lub tswb nrov, valve tswj, Token code tuaj yeem rov pib dua lub ntsuas dej, thiab lwm yam. Muaj nuj nqi;
• CIU siv LoRa wireless los tsim cov lej Token, thiab kev sib txuas lus nyob deb ntawm thaj chaw nyob tsis tsawg dua 300 meters;
• CIU thiab cov neeg siv STS cov ntsuas dej tuaj yeem ua khub ib-rau-ib lossis cov khub tuaj yeem hloov pauv;
• LCD muaj nuj nqi zaub pab cov neeg siv los nyeem cov ntaub ntawv ntsuas thiab rov them cov ntaub ntawv.
• Independent roj teeb compartment, lub roj teeb yog yooj yim los hloov
• Kev tsim kho tshuab thiab hluav taws xob sib cais ua rau kev pab cuam tom qab muag yooj yim dua

• Ua haujlwm zaus: 868MHz zaus band, tuaj yeem ntab nce thiab nqis ± 10MHz.
• Modulation method: LoRa linear zaus modulation.
• Kev siv hluav taws xob: qhov nruab nrab zoo li qub tam sim no<30uA, maximum power consumption during meter reading <2mA (use ER26500 lithium sub-ion battery to read the meter once a day and have a service life of not less than 6 years).
• Fais fab mov voltage: 3.0V ~ 3.6V.
• LoRa kev sib txuas lus nrug: tsis pub tsawg tshaj 1000 meters kis tau tus mob nyob deb (nyob rau hauv qhib qhov chaw), thiab kev sib txuas lus nyob rau hauv cov cheeb tsam tsis tsawg tshaj li 300 meters.
• Kev khiav hauj lwm kub ntawm hluav taws xob qhov chaw: -40 degree ~ 85 degree .
• Ua hauj lwm av noo ntawm hluav taws xob qhov chaw: 10% ~ 90%.
• Valve hloov lub sijhawm tos: 20 vib nas this.
• Valve thaiv tam sim no: Ntau dua lossis sib npaug rau 260mA.
• The maximum instantaneous drive current of the valve: >800 mA.
• Pulse sampling lub sij hawm: 0.25 vib nas this.

• Lub tswb hluav taws xob hluav taws xob: Lub tswb ntsuas hluav taws xob qis yog tshwm sim thaum qhov hluav taws xob qis dua 3V.
• Magnetic nres tswb: Thaum lub ntsuas dej nkag siab tias qhov sib nqus induction siv tau cuam tshuam rau kev sau thiab ntsuas, lub tswb sib nqus nres tau tshwm sim.
• Anti-disassembly tswb: Txais lub tswb nrov muaj nuj nqi. Thaum disassembly raug ntsib, cov kev hloov hauv cov hlau nplaum raug kuaj pom thiab lub tswb muaj nuj nqi tshwm sim.
• Lub tswb tsis txaus: Thaum cov dej haus ntau dua li qhov sib npaug, lub tswb ua haujlwm tau ua rau offline.
• Overdraft npaum li cas tswb: Lub tswb muaj nuj nqi yog tshwm sim thaum cov dej siv ntau tshaj li cov nyiaj overdraft.
• Flow tswb: Yuav xa ib lub tswb thaum siv dej tas li tshaj 24 teev; tswb thaum qhov siab tshaj plaws niaj hnub siv tshaj qhov kev siv teeb tsa; tswb thaum muaj nruam rov qab ntws.
