As a kind of smart water meter, card water meter is widely used in modern water supply system. It realizes efficient management of water resources through advanced technology. This paper will deeply discuss the working principle, internal structure and functional advantages of the card water meter.
Working principle
The core working principle of the card water meter is based on the traditional mechanical water meter, but it adds electronic control and data transmission functions. Here is the basic workflow:
User identification: The user activates the water meter by swiping an IC card or NFC card.
Data reading: The water meter reads the information in the IC card, including the user identity and the amount of water stored.
Water metering: The mechanical part inside the water meter (such as gears, counters) is measured according to the water flow through the meter.
Data update: The water meter writes the water amount information back to the IC card.
Display and control: The display of the water meter will show the remaining water in real time, and once the water is used up, the water meter will stop supplying water.
Internal structure
The internal structure of the card meter usually includes the following key parts:
Mechanical metering part: including gears, counters, etc., for measuring the flow of water through the water meter.
Electronic control unit: contains a microprocessor and memory, responsible for reading the IC card information, controlling the valve switch and data storage and processing.
Display module: Used to display the current water information and status.
Power module: Usually provides battery power to ensure the continuous operation of the water meter.
Communication module: used for data exchange with IC card.
Valve control: According to the remaining water information control valve switch.
Functional advantage
Compared with traditional water meters, credit card water meters have the following significant advantages:
Prepaid function: Users must recharge before use, effectively avoiding the problem of unpaid fees.
Real-time monitoring: Users can learn about water use in real time, helping to develop water-saving habits.
Remote control: By swiping the card operation, you can realize remote control of the valve opening and closing.
Data security: Data encryption in the IC card ensures the safety of user information and water data.
Easy maintenance: Due to the use of electronic control, the possibility of mechanical failure is reduced, and maintenance is easier.
Intelligent management: It is convenient for water supply companies to carry out remote meter reading and user water consumption data analysis, and improve management efficiency.
With the development of science and technology and the promotion of smart city construction, card water meters are gradually becoming the preferred solution for water supply management. It not only improves the safety and convenience of water use, but also promotes the rational use and conservation of water resources. In the future, with the continuous progress of technology, the card water meter is expected to integrate more intelligent functions, bringing more convenience to users and water supply companies.
