Water meter near-field awakening method and system and readable storage medium

Abstract

The invention discloses a water meter near field wake-up method which comprises the following steps that a low-power-consumption activation module and a common-power-consumption information transmission module are preset, and the initial state of the information transmission module is a dormant state; and when the activation module receives an activation instruction of a specified frequency, an awakening instruction is sent to the information transmission module. According to the near-field wakeup method for the water meter provided by the invention, the information transmission module is in a dormant state in most of time by arranging the low-power-consumption activation module and the auxiliary information transmission module, so that the power consumption of the water meter is greatly reduced, and the water meter can be kept for a long time even if the water meter is not connected with an external power supply. The invention further discloses a system adopting the method and a readable storage medium.

Description

technical field [0001] The invention relates to the technical field of smart water meters, in particular to a near-field wake-up method and system for a water meter and a readable storage medium. Background technique [0002] With the advancement of science and technology, more and more electrical equipment has become intelligent, and the equipment can be easily controlled through remote control equipment. [0003] As a necessary equipment for every family, water meters have gradually transitioned from mechanical water meters to electronic water meters. Smart water meters are currently being popularized. Through remote terminals, such as mobile phones or control centers, you can easily obtain water meter information and adjust the status of the water meter. At present, due to cost considerations, most water meters use near-field wireless connections such as infrared, Bluetooth or NB-IOT to operate the water meter. [0004] Since it is necessary to establish a wireless conne...

AI Technical Summary

Problems solved by technology

[0004] Since it is necessary to establish a wireless connection between the near field and the water meter, the water meter needs to be continuously connected, but this will cause a large power loss of the built-in battery of the water meter, and a stable power supply must be connected externally. Once the external power is cut off, the water meter will stop working and cannot be used for areas with unstable electricity
