Water meter, mobile terminal, water flow obtaining system and method thereof

Abstract

The invention discloses a water meter which comprises a turning wheel module, a controller, a storage and a radio frequency identification (RFID) electronic tag, wherein the turning wheel module is used for detecting water flow and sending the water flow into the controller. The controller is used for writing the water flow into the storage to be stored. The storage is used for storing the water flow. The RFID electronic tag is used for receiving a drive command of an RFID reader to read the water flow stored in the storage and sending the water flow to the RFID reader, wherein the identification information of the water meter is identified on the water flow. The invention further discloses a mobile terminal, a water flow obtaining system and a method of the water flow obtaining system. The water meter, the mobile terminal, the water flow obtaining system and the method of the water flow obtaining system obtain the water flow stored in the water meter storage simply and conveniently through the RFID method, avoid error of reading of the water meter, bring convenience for a meter reader to operate, and facilitate export, analysis and processing of data during a follow-up process.

Description

technical field [0001] The invention relates to a water meter, a mobile terminal, a water flow acquisition system and a method, in particular to a water meter, a mobile terminal, a water flow acquisition system and a method capable of realizing remote meter reading. Background technique [0002] RFID (Radio Frequency Identification) is radio frequency identification technology, also known as electronic tags; it is a non-contact identification technology that can identify specific targets through radio signals and read and write related data. There are many types of RFID and it is also widely used. Short-distance communication such as: access control system, bus system, electronic wallet, etc.; long-distance communication such as: animal tags, cargo management, etc. [0003] Now the meter reading system of the water meter is also gradually moving towards digitization and informatization. There are many meter reading systems on the market. There are wireless meter reading syst...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the need to rely on manual meter reading to read the water flow of the water meter in the prior art, which is prone to misreading, misreading, and slow reading speed, which wastes manpower and material resources. Building a repeater in the community, the cost is high, and the water flow data cannot be transmitted to the data center in a timely and effective manner. It provides a method that does not need to read the data with the naked eye, saves manpower and financial resources, and can realize data exchange without a repeater.
