Qhov txawv ntawm LoRa thiab GPRS dej ntsuas dej yog dab tsi
In current, our wireless remote reading water meter mainly divided into LoRa and GPRS system.This article wish to give you a brief introduction about lawv.
LoRa dej ntsuas qhov system xa thiab tau txais cov cim qhia los ntawm lub ntsuas dej thiab LoRa cov ntaub ntawv concentrator los ntawm LoRa teeb liab. Koj tuaj yeem nyeem thiab tswj cov dej ntws ntawm lub computer wirelessly.
GPRS water meter system transmits and receives signals from water meter via 2G signal. Each water meter built-in a SIM card module.You can reading and control water supply via computer.
LoRa system thiab GPRS qhov system sib txawv hauv kev nyeem ntawv thiab zaus.
1.LoRa cov kev nyeem cov ntaub ntawv muab faib ua active nyeem ntawv thiab passive nyeem ntawv.
--Kev nyeem ntawv nquag, tam sim no sib sau ua ke ntawm cov ntsuas dej tuaj yeem nyeem los ntawm lub platform.
--Passive kev nyeem ntawv, los ntawm lub platform teeb concentrator upload lub sij hawm thiab zaus rau kev nyeem cov ntaub ntawv.
2. Kev nyeem ntawv hom ntawm GPRS dej ntsuas qhov system yog kev nyeem ntawv passive. Qhov kev nyeem ntawv zaus ntawm lub ntsuas dej yog ib zaug 3 hnub lossis ib hnub ib zaug (yeem).
The installation conditions requirements of these two water meters are as follows:
1. LoRa
1) Intensive installation ntawm dej ntsuas
2) Cov khoom siv hluav taws xob sab nraud tuaj yeem ua kom lub cev ua haujlwm ntawm cov ntaub ntawv concentrator
3) Kev siv siab ntawm SIM Card teeb liab (2G / 3G / 4G) rau cov ntaub ntawv concentrator
2.GPRS
1) Txhua lub ntsuas dej yuav tsum ua haujlwm nrog ib daim npav 2G SIM
2) Yuav tsum muaj siab GPRS teeb liab (2G teeb liab) siv
That's tag nrho, ua tsaug. Yog tias koj xav tau, txais tos hu rau peb kom paub meej ntxiv.
