Abstract

The invention relates to a one-card and multi-meter multi-mode charging radio frequency card prepaid intelligent water meter and a charging method. The intelligent water meter comprises a valve driving circuit, a power management circuit, a display module, a read-write card module, a storage and a microprocessor; the read-write card module is used for reading a card; the microprocessor comprises an allocation module, a card information collection module, a total water consumption calculation module, a valve status monitoring module, a power judgment module, a flow collection module and a differential charging module; the allocation module is used for allocating limiting charge and charging differentials for the differential charging module; the card information collection module is used for reading and writing the recharge amount from the read-write card module; the total water consumption calculation module is used for sending a pulse signal according to a flow sensor to calculate the total dosage and sending the total dosage to the differential charging module. According to the one-card and multi-meter multi-mode charging radio frequency card prepaid intelligent water meter and the charging method, a one-card and multi-meter mode is adopted, only one user card is needed by old user transformation with multiple water meters, and the management difficulty to the users is reduced.

Description

technical field [0001] The invention relates to a multi-mode charging radio frequency card prepaid intelligent water meter with one card and multiple meters and a charging method. Background technique [0002] As the country’s awareness of the importance of water resources has gradually increased, rational water use and water conservation have become a broad consensus among citizens. The single-price pre-payment and step-by-step charge for water use are effectively combined. An advanced urban water supply charging system with low management cost is urgently needed. This type of water meter can adopt a single-price charging mode or a step-by-step charging method. Intelligent water meter products are provided for the realization of urban water supply ladder billing and water-saving management. [0003] As a new technology, radio frequency IC card has the characteristics of no contact, no pollution, moisture, easy operation, and strong adaptability to the environment. At pre...
