Section 1. Overview
Under the current situation, the global pollution is gradually serious, and the management and conservation of water resources has become a worldwide problem. China has a large population and limited available water resources. When the available water resources are seriously polluted, saving existing water resources has become a top priority.
The energy-saving control system developed by our company adopts the MIFARE I type originally produced by PHILIPSNon-contact IC card, The card has a 32-bit unique serial number in the world, has strict logical operations and logical encryption functions, and a storage capacity of up to 8Kbit. It is divided into 16 sectors to support multiple applications, and each sector has its own set Password, can customize the access conditions of each sector, far superior to magnetic cards and ID cards in terms of read and write speed, read and write security, system scalability, etc., use high-performance energy-saving controller to automatically control the water outlet solenoid valve to discharge water When shutting down the water, the energy-saving controller automatically charges according to the actual water or electricity consumption, and automatically charges from the IC card e-wallet; it is suitable for bath shower charge control, boiling water/hot water charge control, drinking water charge control, and electricity use Charge control, laundry charge control, agricultural irrigation, green watering, industrial water, warm air supply control and other small consumption applications.
The energy-saving controller can run offline and collect data with a hand-held acquisition card. It can also be connected to the management computer through the network to use energy-saving management software for equipment parameter setting, consumption data collection and query, statistics, reports, settlement and other processing. So as to achieve the purpose of saving water and electricity, scientific charging and efficient management.
This system is simple to use, easy to operate, and powerful. It completely replaces outdated consumption methods such as cash, tickets, and magnetic cards. Using the multi-sector feature of MIFARE I, it can easily expand a variety of functions, such as: canteens, commissaries and Supermarket shopping, medical fees, faculty and staff attendance, dormitory access control management, computer online charging management, student status management, parking lot fees, etc. can all be realized by virtue of the card’s one-card multi-purpose performance.

3. Control system business process
The system adopts the prepayment method for hydropower control and management, and the normal use process is as follows:
Put the card and press the start button to discharge the water and press the stop button to take the card
1) The consumer inserts the recharged user card into the energy-saving controller, and the energy-saving controller automatically determines whether the card is a valid card. If the card is legal and valid, the energy-saving controller is allowed to be used. If it is an illegal card or invalid card, an alarm will be issued and the energy-saving controller is not allowed to be used. (The number of times of use and the time of use are set by the setting card).
2) When consumers need water, they only need to press the start button of the energy-saving controller, and the water/electricity control device immediately releases water and the timing starts. The energy-saving controller displays the usage time.
3) After use, the consumer pulls out the user card from the energy-saving controller, and the water control device immediately cuts off the water. And disable the start button until the next card is used.
4) If the number of uses in the user card has been deducted, the water control device will immediately cut off the water and the button will become invalid. You must wait until the next day before you can continue to use it.
The manager can collect the charging data in the energy-saving controller through the acquisition card. Card management such as user card issuance, card replacement, and recycling is handled by the smart card center in a unified manner.
4. Functional characteristics of energy-saving control system

2) Realize automatic water supply control and charging, can realize unattended, adopt electronic wallet transaction, avoid management loopholes and be more scientific and efficient.
3) Charge deductions based on actual water consumption or electricity consumption, and start timing of water discharge, which achieves personalized consumption and energy saving, fair and reasonable for consumers and contractors, and takes into account the interests of both.
4) As the timing can be seen, users will consciously shorten the water and electricity time and increase the turnover rate of water supply/power supply equipment, thereby saving resources.
5) Cultivate people’s awareness of saving, benefit the country and enterprises, and promote the construction of spiritual civilization. IC card management is convenient and accurate, which improves management efficiency and grade.
