Problems solved by technology

However, since the way of magnet activation is not particularly controllable, it is easy to cause misoperation during production and transportation
Using infrared communication, for infrared communication, it is necessary to set a transparent window on the water meter product for communication, which is also a challenge for the waterproof performance design of the product

Abstract

The embodiment of the invention provides an NB-IOT (Narrow Band-Internet of Things) water meter and a processing method. The water meter comprises a main control unit and a power supply unit, whereinthe main control unit comprises a microprogrammed control unit (MCU), a metering sensation module, a near field communication (NFC) module, and a narrow band-internet of things (NB-IOT) module based on a honeycomb; the metering sensation module is used for acquiring water meter data and used for transmitting the water meter data to the MCU; the NB-IOT module is used for receiving data which are transmitted from the MCU and are to be transmitted, and is used for remotely transmitting the data to be transmitted; the NFC module is used for communicating with an external NFC terminal and is used for transmitting an interruption signal to the MCU to awaken the water meter. According to the embodiment of the invention, the NFC module with an interruption output function communicates with the external NFC terminal to transmit the interruption signal to the MCU to awaken the water meter, an awakening button is not needed, the waterproof property of the water meter can be improved, in addition,as a button circuit is replaced by the interruption signal, a false triggering rate can be reduced.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to an NB-IOT water meter and a treatment method. Background technique [0002] In the field of wireless remote water meters, power is often provided by the power supply mode of the built-in lithium battery in the water meter. Taking the power supply of 3.6V lithium battery as an example, the power consumption of an NB-IOT terminal to transmit data online is 1-2mAh, which is relatively large. [0003] Therefore, in order to reduce unnecessary power consumption, the water meter is set with a fixed background server address when it leaves the factory. After the in-factory test is passed, the mode of the water meter is set to the in-factory mode, thereby forcing the water meter NB mode to be in a non-working state. After leaving the factory, activate the NB mode of the water meter through other communication methods to ensure that the water meter will not consume a lot of power du...
