  Industry pain points

1, Water meter is an important link between water supply enterprises and terminal customers , Its collection is accurate , security , Reliable data is very important . 

2, Traditional mechanical meters have certain advantages in cost , As labor costs rise , Manual meter reading mode is inconvenient for both enterprises and users , And the efficiency is not high .

3, Intelligent meter can realize remote meter reading , Remote valve control , Fault detection , Abnormal alarm and other functions , But the water meter is often placed in the corridor or underground , In the early stage, wireless coverage is not perfect , It limits the popularization and promotion of intelligent water meter in the market .

 

Built in security engine

Guanghetong smart meter NB-IoT Solution

this year 5 month , Issued by the Ministry of industry and information technology 《 Notice of the general office of the Ministry of industry and information technology on further promoting the comprehensive development of mobile Internet of things 》 It is emphasized that : reach 2020 end of the year ,NB-IoT Network to achieve universal coverage of main urban areas of cities above county level , Deep coverage of key areas ; Create a group of NB-IoT Application of benchmarking and NB-IoT Application scenario of Megascale connection .NB-IoT This year 7 Month officially written 5G standard , with NB-IoT Mobile Internet of things is the future 5G An important part of IOT strategy . up to now , Construction of three major domestic operators NB-IoT The total number of base stations is about 83 ten thousand , Formed a town , Rural continuous coverage NB-IoT network .

NB-IoT Wide coverage , Big connection , The characteristics of low power consumption can solve the pain point of intelligent water meter network coverage , Provide stability for remote meter reading , Secure data transmission . Guanghetong with built-in security engine NB-IoT Communication module , Provide end-to-end wireless data transmission and access for water supply enterprises , Common security vulnerabilities of water system , Nip in the bud .

Fibocom NB-IoT Series safety modules adopt SM2,SM4 Algorithm for encryption and decryption , Signature verification based on SM3,SM2 algorithm . Self generated public private key pair , The private key does not come out of the security engine ; Support online certificate issuance ; Define industry safety baseline , Perceived risk ; Full flow analysis , Embedded Firewall . Enabling efficiency , Secure data collection .

NB-IoT Smart water meter helps reduce meter reading cost , Real time data analysis , Scientific table management , Timely troubleshooting , Improve operational efficiency . Benefit from technology , policy , standard , The collective boost of operators and upstream and downstream industries ,NB-IoT It is developing rapidly in China ,2019 The annual user scale has exceeded 1 Billion . along with 2020 year NB-IoT Officially become ITU
5G R16 standard , As the demand side NB-IoT Smart meter industry will also enter a period of accelerated growth in the future .
