Abstract

The invention provides an NB-IoT (narrowband internet of things) water meter system, comprising, an NB-IoT water meter terminal, an NB-IoT base station and an IoT water meter platform; the NB-IoT water meter terminal reads water consumption information displayed on a water meter through a photoelectric direct-reading core and transmits to an NB-IoT core network through the NB-IoT base station; theNB-IoT base station transmits collected water consumption data and identity information of a water consumer unit to the IoT water meter platform through the IoT core network; the IoT water meter platform issues a control command and data information to the NB-IoT base station through the IoT core network; identity information, water consumption data and charging data of the water consumer unit are transmitted to the internet-of-things industry for use through the internet. The NB-IoT technique is used herein to directly read a 'window value' of the water meter through an IoT water meter terminal and the photoelectric direct-reading core, fault points of existing IoT water meters that using cumulative pulse conversion are avoided, and the water meter can be direct-read precisely.

Description

Technical field [0001] The invention relates to the technical field of smart water meters, in particular to a NB-IoT Internet of Things water meter system. Background technique [0002] At present, most of the existing water meters adopt manual meter reading methods, and there is an increase in labor costs and management costs year by year, and there is a risk of human error. The water meter of manual property management has problems such as inaccurate measurement caused by improper management, which is easy to cause residents' water fee disputes; leakage of the water supply pipe network in the meter reading area is not easy to find, and there is a waste of water resources; short-distance wireless RF remote meter reading method , There are potential difficulties in long-term network maintenance, and the use of public frequency bands is susceptible to interference. [0003] The embedded wireless chip in the smart water meter allows it to automatically report measurement data on a r...
