Research on intelligent water meter based on NB-IoT
摘要
产销差高、运营成本高是供水企业最大的痛点
为此
水表行业1990年左右开始进行智能水表的探索。本文首先梳理了智能水表的发展之路
从有线到无线、从短距离通信到长距离通信、从非运营商网络到运营商网络
比较得出目前NB-IoT是一种理想的技术
然后基于NB-IoT设计智能水表的网络架构和工作方式
最后分析基于NB-IoT的智能水表的优势。
Abstract
High difference between production and sales and high operating costs are the biggest pain points for water companies. For this reason
water supply companies have long been exploring intelligent water meters. This article fi rst combed the development of intelligent water meters
from wired to wireless
from short-range communications to long-distance communications
from non-operator networks to operator networks. NB-IoT is regarded as the ideal technology. Then the network architecture of intelligent water meter based on NB-IoT and the working mode of intelligent water meter are designed. Finally
the advantages of intelligent water meter based on NB-IoT are analyzed.
