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 .
