NB-IOT intelligent water meter system

Abstract

The invention relates to an NB-IOT intelligent water meter system, whichuses a 4G network technology of NB-IOT to achieve large connection and deep coverage of data, simultaneous uploading of tens ofthousands of water meters in an area can be achieved and the data can be quickly and accurately analyzed and updated, and the data is stably and safely transmitted in a hard well cover 1 meter underground and an underground official net. A technical scheme of low power consumption can greatly reduce the time and labor cost of manual line arrangement and debugging, and the technical scheme of battery power supply is achieved by using the low power consumption technology of NB-IOT, the uploading frequency of the data can be set through a platform so as to meet different periodic requirements ofdifferent clients on data acquisition; under the mode of low power consumption, a power consumption standard of 20UA can be reached, and the requirement that batteries do not need to be replaced for 8-10 years can be achieved under the cycle of data uploading frequency of once a day.

Description

technical field [0001] The invention relates to the field of smart water meters, in particular to an NB-IOT smart water meter system. Background technique [0002] As we all know, water meter reading is an important link in the management and charging of the water meter industry. For a long time, most of China has adopted manual meter reading, and some of them use LPWAN (low-powerWide-Area Network, low-power wide-area network), including LoRa with unlicensed spectrum. , SigFox, etc. and 2 / 3 / 4G cellular communication technology. The traditional meter reading method is error-prone, the cost of manual monitoring is high, and the power consumption of equipment is large; based on NB-IoT technology, it has the advantages of wide coverage, low power consumption, large connection, and low cost that other communication technologies do not have. Some problems that are widely used in tables, such as poor transmission data stability, high power consumption, weak wireless network covera...
