NB-IOT (Narrow Band Internet of Things) water meter system

Abstract

The invention discloses an NB-IOT (Narrow Band Internet of Things) water meter system, which comprises an NB-IOT water meter acquisition end, an NB-IOT base station, an IOT core network, an IOT water meter cloud platform and an NB-IOT client terminal, the NB-IOT Internet of Things base station comprises a first information receiving and sending module group which forms one-to-one pairing of independent frequency bands with information sending modules of the NB-IOT Internet of Things water meter collection end. The IOT core network comprises a second information receiving and sending module group which can be in wireless transmission connection with the first information receiving and sending module group; the NB-IOT Internet of Things base station further comprises a first encryption end; the NB-IOT water meter system comprises a first encryption end and a second encryption end, the IOT water meter cloud platform comprises a second encryption end, the NB-IOT water meter system applies an independent frequency band communication technology, a filtering technology and an encryption technology on a plurality of wireless connection platforms, so that communication of the NB-IOT water meter system is smoother and more efficient, and confidentiality of information wireless communication is greatly improved.

Description

technical field [0001] The invention relates to the technical field of smart water meters, in particular to an NB-IOT Internet of Things water meter system. Background technique [0002] Because traditional smart water meter reading has many problems such as difficult real-time monitoring, complex construction, high cost, and poor communication stability, with the emergence of NB-IoT narrowband Internet of Things technology, this situation will be fundamentally changed. Based on NB--IoT technology, it has the characteristics of wide coverage, high reliability, high security, low cost, and low power consumption. In the field of smart water meters, it can not only reduce the cost of meter reading, but also realize the intelligentization and big data of water meter management. Management has very important practical application value. NB-IoT smart water meter system is mainly composed of water meter with NB-IoT communication module, NB-IoT communication base station, IoT cloud...
