Functions of charging, water control and one-card system. It is specially designed for multi-user places such as dormitories and public baths in schools. It supports independent charging for multiple user cards corresponding to one water meter, realizing a fair water usage management model of "pay as you use".

1. Energy and water conservation, reducing operating costs: Effectively eliminates the "running water" phenomenon, significantly reducing water consumption and energy usage (typically by 30% to 50%), saving considerable water, electricity, and fuel (for hot water) expenses for schools.
2. Fair consumption, pay-as-you-use: Transforms water resources from a "benefit" to a "commodity", implementing the principle of user payment, significantly enhancing students' awareness of water conservation.
3. Intelligent management, efficiency improvement:

• No need for manual supervision or manual charging.
• Remote monitoring of equipment status, with rapid response to faults.
• Automatic generation of financial data, clear accounts, and elimination of financial management loopholes.

1. Enhanced user experience:

• One card for all uses, convenient and fast.
• Supports multiple payment methods, catering to the habits of the new generation.
• Instant loss reporting takes effect, ensuring fund security.

1. Data-driven decision-making: Through big data analysis of water usage, it can optimize boiler operation times, pipeline layouts, and even serve as a reference for student behavior analysis.

1. Public student bathhouse: The most core application scenario, solving the problems of long queues for showers and serious waste of water resources.
2. Boiling water room: Water is dispensed as needed, avoiding the use of thermos flasks to "reserve" and waste.
3. Independent bathroom in dormitories: In some universities that implement quota water usage or refined management, they are also installed in the independent bathrooms of dormitories.
4. Public laundry room: Similar to the water control system, it can be integrated to control the start and stop of washing machines and charge fees.

The "multi-card water control machine for campus and bathrooms" is not merely a hardware device; it is a comprehensive energy management system integrating identity recognition, payment settlement, resource control, and data management. It successfully combines technology with management, providing convenience for students while generating significant economic and social benefits (environmental protection) for the school. It is a very successful and mature application model in the construction of modern smart campuses.
