Overview of Beijing Jiangwang Technology JW-SK3 Bathroom Card Swipe Water Saving System

Beijing Jiangwang Technology Co., Ltd. offers the Bathroom Card Swipe Water Saving System, a water-saving control management system based on IC smart card consumption, named JW-SK3. This water control machine is an all-in-one device integrating a water-saving valve and a card reader controller, featuring functions such as water saving, time-based billing, usage-based billing, and metered billing. It is not only compatible with existing IC card systems but can also serve as an extension of a one-card system.

Technical Parameters

Card Reading Type The JW-SK3 water control machine supports MIFARE ONE standard cards, with a card reading speed of less than 0.2 seconds and a reading distance of 3-6 cm. This contactless IC card technology offers advantages such as no physical contact, ease of use, higher security, and reliability.

Compatibility The water control machine is highly compatible and can integrate with various systems such as meal vending, attendance, access control, computer room management, and library management to form a one-card system, enabling multi-functional use with a single card.

Display The water control machine features an LCD display that shows information such as rates, time, and card balance. Rate settings can be configured offline using a management card.

Operating Voltage and Power Consumption The JW-SK3 operates at a DC12V voltage, with a standby power consumption of 1.6W and a power consumption of less than 5W during card-swiping water supply, helping to reduce energy consumption.

Dimensions and Packaging The product dimensions are 200 mm × 133 mm × 47 mm, and it comes in standard packaging.

Functional Features

Standby Display In standby mode, the water control machine displays the current date and time.

Real-Time Deduction Mode In real-time deduction mode, the water control machine operates when the card is within the sensing area and stops when the card is removed. Upon card reading, the card balance is displayed first (for 10 seconds), followed by the first four digits showing the real-time usage time (in seconds) or flow rate (in liters), and the last three digits showing the real-time consumption amount (in cents).

Pre-Deduction Mode Pre-deduction mode allows users to deduct a certain amount in advance when swiping the card, followed by actual deductions. If water supply is interrupted midway and the card is swiped again, the remaining balance will be refunded to the card.

Billing Methods The JW-SK3 supports two billing methods: time-based billing and flow-based billing. Time accuracy is up to 1 millisecond, and amount accuracy is up to 0.1 cent. Additionally, an external pulse flow meter can be connected to calculate the flow generated for billing. The current pulse flow meter measures 1 pulse per liter of water.

Control Valve Types The water control machine supports controlling two types of valves: solenoid valves and motorized valves, providing flexible control options.

Three Consumption Modes The JW-SK3 supports three consumption modes: real-time deduction, pre-deduction, and per-use billing.

Independent Wallet System The system supports two independent wallets: a personal top-up wallet and an enterprise subsidy wallet. By default, the subsidy wallet is deducted first, and the personal wallet is deducted only after the subsidy wallet balance is exhausted.

Free Cold Water Function This feature allows users to set a value. Each time a card is swiped, the system checks whether the time elapsed since the last swipe exceeds this value. If it does, the system automatically waives a certain amount of the fee.

Time Slot Settings Up to three water usage time slots can be set. Card swiping is disabled outside these time slots. Settings can be configured using a time slot setting card.

Card Data Collection Terminal The system can record daily or monthly water usage time or volume for each card. Total amounts can be collected via the card data collection terminal.

In summary, the JW-SK3 Bathroom Card Swipe Water Saving System by Beijing Jiangwang Technology Co., Ltd. is a powerful and highly efficient smart water control device.
