The non-contact IC card water control and energy-saving intelligent management system combines personal interests with reasonable consumption. Greatly improve the water-saving awareness of water people, so that the waste of water in factories, schools, public places, etc. has been effectively solved.

1.1 Overview:

The non-contact IC card water controller realizes that the philips mifare1 non-contact IC card is used as an electronic wallet to deduct the amount in the card in real time in a prepaid manner, and accurate billing and water saving are achieved through the on-off control of the solenoid valve of the outlet pipe. The billing method is timing or flow metering. The controller has an 8-digit digital tube display, which can display the balance, rate, etc. in the card. For the water controller, a consumption refers to inserting a card into the induction area of the controller to start charging until the card is removed. The controller can accumulate the total consumption and can also save the latest 1000-4000 consumption records. The controller can work in a stand-alone computer or in a network. The parameter setting and data collection can be done through the management card, or computer software can be collected through the network, and the total consumption can be directly queried on the controller.
