Program overview
The water control system was first used in 2002, and it has been more than 5 years. It has been gradually recognized by people and the market demand is increasing. This is enough to show that the water control system can bring good economic benefits to the user. For example, the price of a water control machine is about 500 yuan, and the warranty period is 2 years. It is converted into 500÷(365×2)=0.68 yuan per day, plus the daily power consumption is 2W×24÷1000 = 0.048 degrees. According to 1 yuan per kilowatt-hour of electricity, it is less than 0.10 yuan, and the total cost is less than 0.80 yuan per day. The use of a water control system in the hot water supply has saved more than 1 yuan of hot water per person per day. If 8 people in a dormitory share a water control unit, the benefits will be more obvious. For the whole society, it can not only enhance people’s awareness of water saving, but also create benefits for society.
Features of this program:
1. The data of the consumer IC card is absolutely safe and will not be cracked
The MIFARE 1 S50 card that uses the ISO/IEC 14443 TYPE A standard is similar to Guangzhou’s Yangchengtong. This type of card has a 4-byte global unique serial number, and has strict logical operations and unbreakable logical encryption functions. Each card contains 16 e-wallets that can be used independently, and each e-wallet has its own password. It is the best choice for factory and campus all-in-one cards.
Only one of the e-wallets is used for information such as consumption balance and cumulative water consumption for the day. If there is already an IC card consumption system, as long as an electronic wallet can be opened on the original card, it can be compatible with the original consumption system.
Two), easy to manage, easy to use
1. Put the card to take water; take the card and cut off the water; first deduct the money and then use the water; automatic water supply control and charging, realizing unattended management.
2. The water control machine has the perfect feature of displaying various information in Chinese, which brings great convenience to ordinary users and administrators, which is a bright spot of this system.
By displaying familiar Chinese and graphics on the LCD screen. In this way, accurate information is brought to ordinary users and managers. Prompts such as consumption balance, accumulated usage, insufficient balance, malfunction and other issues are all displayed in Chinese, achieving the effect of being clear to users at a glance. To achieve the purpose of man-machine dialogue.
(1) The prompt information display interface, as shown in the figure below: .jpg)
Three), powerful, able to cope with various water-saving methods
Charging method: In order to meet different charges, the water control machine implements stepped charging.
(1) Different prices are set according to the cumulative water consumption of the day.
(2) Set a uniform price for all steps to achieve non-step rates. If the prices are set to zero, free water can be achieved.
(3) Setting the upper limit of water consumption can control the daily water consumption.
(4) Set water time period, 4 time periods can be set. Card swiping at other times is invalid.
(5) With a temperature probe, separate charges for cold water and hot water can be realized.

2. One machine with multiple cards, billed according to flow rate (liter) or time (second). Put the card in the sensor area of the water control machine to fetch water. After removing the card, the water will be cut off immediately, automatic water supply control and charging, unattended management, electronic wallet transactions, avoid management loopholes, and make management scientific and efficient.
3. Support mifare one card, sensing distance 50mm to 100mm.
4. Tiered price billing method, different accumulated usage charges are charged at different prices, real-time deductions, and personalized charges are realized. Use more deductions instead of deductions. As billing deductions are visible, users will consciously shorten the water use time, eliminate water waste, save precious water resources, cultivate people’s awareness of conservation, benefit the country and the people, and promote the construction of spiritual civilization. IC card management is convenient and accurate, which improves management efficiency and grade.
5. Regular water use, hot (cold) water can be set for four time periods of water use every day.
6. Limited water use, which can be used according to the day’s quota.
7. The function of checking the maximum and minimum amount, and the alarm function of insufficient balance.
The above functions can be set to the swipe card setting on the water control machine through the system management software to make the corresponding function card.
8. Chinese LCD display, complete operation prompts. There is also a fault prompt. When a certain part of the module fails, the problem can be quickly resolved according to the fault prompt. Built-in electronic watchdog, when the external environment interference causes the water controller to crash, it can automatically restart and automatically detect.
9. The circuit board is sealed and completely separated from the water circuit. It is convenient for users to replace waterway accessories such as valves by themselves, and the applicable water pressure is 0.2MPa-0.8MPa.
10. Prevent the water stealing behavior of “drip water without leaving the watch”. It is charged like a taxi. When the card is placed in the induction area, if there is no flow, it will automatically be charged by time, which is converted into 1 liter of water every 2 minutes, and the solenoid valve will be automatically closed after 30 minutes.
11. The system management software adopts the XP graphic interface. Operators with a little computer basis can operate without training. Every step of the operation has an immediate help or reminder function, which can avoid illegal operations or misoperations. Operator authority can be set. For example, the operator can set the authority to recharge and issue new cards, and the department leader can set the authority to only query the income and expenditure situation, and correct misoperations require administrator password authentication and other functions. System data is safe and reliable, and can be backed up online. The management software functions include: issuing new cards, recharging, inquiring about the balance or personal information on the card, income and expenditure and summary inquiry, and related financial statements can be printed or exported as electronic forms for reprocessing.

Installation Notes
The installation procedure is to install the water controller on the water pipe first, and then install and connect the power line after it is fixed.
Installation Precautions:
1. The water control unit itself has a water flow direction. When installing, you must pay attention to the direction arrow on the bottom of the water control cabinet to be consistent with the water flow direction.
2. Two sets of water meter joint connectors (nuts, copper sleeves, silicone pads) are delivered in the water controller package. Please note that the nuts of these two sets of water meter joints are different. The nut with a higher column is installed in the water controller. On the side of the water inlet of the machine, the shorter column is installed on the side of the water outlet. According to the length of the water controller, connect the water meter joints on both sides of the water pipe first, and then install and tighten the water controller.
3. When tightening the water inlet nut of the water control unit, hold the water control unit with one hand, hold the nut with the wrench in the other hand and gently force it, not too forcefully. The water outlet must be clamped with a thin-arm wrench with one hand and the nut with a wrench with the other hand.
Fourth, the installation of the power supply is best to install a general electrician socket in a safe place, not easy to be splashed by water. The power adapter must be securely inserted and not easy to fall. Note that the socket must be 220V city power.
5. Connect the output line of the power adapter to the power line of the water control unit. If it is not displayed, please connect it backwards. The water control unit has circuit protection and will not burn if connected reversely. If the line is not long enough, please connect and extend it by yourself.
