Integrated water meter used in Internet of Things and integrating water purchasing setting and water metering

Abstract

The invention discloses an integrated water meter used in the Internet of Things and integrating water purchasing setting and water metering. The water meter comprises a water buying character wheel set used for displaying the water buying amount, a numerical value setting assembly, a valve assembly arranged on a water meter water outlet leading to a water pipeline of a user in an opening or closing mode, a touch valve closing assembly used when the numerical value of the water buying character wheel set returns to zero, a secret key assembly which is used for opening the numerical value setting assembly and the valve assembly according to a starting password configured by a water affair management center for a target water meter, and a reverse counting gear which is used for synchronously driving character wheels in the water purchasing character wheel group to reversely rotate according to the water consumption of the target water meter. According to the water meter, not only is the phenomenon of irregularities in water buying and water consumption management thoroughly eradicated, but also the water affair management center accurately and scientifically manages water meters in a jurisdiction range through the Internet through scientific structural design and an intelligent encryption and decryption structure; and an Internet of Things management mode of accurate, real-time, real and rapid transmission of water selling data in the water supply process is realized.

Description

technical field [0001] The invention relates to a water meter, in particular to a water meter with an encryption device and capable of setting the amount of purchased water through intelligent control. Background technique [0002] In the prior art, the treatment method for users to use water in a prepaid manner is basically completed in the following manner. [0003] In the first step, the user goes to the card sales point designated by the competent company (referring to the water company) to purchase an IC recharge card, and recharges the corresponding amount of water that can purchase a set amount (measured in cubic meters) into the IC recharge card as required Inside. [0004] The second step is to interconnect the IC recharge card with the corresponding mechatronic IC card meter (also known as IC card prepaid water meter or IC card water meter) in a contact or non-contact manner, and then the meter can be started to work (that is, the The meter opens the water valve ...

AI Technical Summary

Problems solved by technology

[0007]1) Whether it is a non-contact IC card water meter or a contact IC card water meter, it is impossible to recharge online, and the user needs to bring the user card to the designated water sales point for recharging There are restrictions on the time and location of recharging, purchasing water, and the waiting time for recharging is long, which brings great inconvenience to users' daily life

[0008] 2) IC card water meters are difficult to prevent recharge fraud

[0009]3) Due to the pre-purchased water volume of the IC card water meter, the user's water consumption cannot be synchronized to the background, resulting in long-term financial suspension of the water company ("account received in advance" is recorded as "debt" in accounting treatment ", so "revenue" cannot be confirmed), seriously affects financial accounting, and is not convenient for monitoring and management of user water use data

[0010]4) The IC card water meter is an independent working entity, and it cannot be monitored in the background. Only when the user reports for repair or conducts water meter inspection can the water meter fault be found, and the fault cannot be detected. Timely detection and elimination, resulting in a disconnect between the meter end and the background management system

[0011]5) The IC recharge card is easily damaged under strong magnetic interference, and it is inconvenient to carry and easy to lose
