IC card water meter is a new type of water meter, which uses modern microelectronics technology, modern sensing technology and intelligent IC card technology to calculate water consumption, transfer water consumption data and settle accounts. The mode of paying first and then using water is adopted, and manual meter reading is not needed. It also has the following characteristics:
1. Using radio frequency card, without any exposed electrodes, it has good moisture-proof performance and is convenient to use.
2. The user card is encrypted with double keys, with one card and one secret.
3. It has the function of one card and one meter, or one card with multiple meters.
4, when the remaining water is insufficient, prompt the user to buy water in time.
5. when the battery voltage is too low, prompt the user to replace the battery.
6. It has the function of data reading back. When a user buys water from the management center with a card, he can read back the accumulated water consumption, battery status and interference times in the table corresponding to the card to the management center.
7. The initial flow is small and the accuracy is high, so the step water price can be implemented.
8. display function: parameters such as the current water purchase, remaining water and accumulated water consumption can be effectively displayed on the LCD screen, and users can view the remaining water and accumulated water consumption information in the table through the user card.
