System Composition

The system consists of three parts: RF card, system management unit, and well irrigation controller.

II. Technical Specifications

1. Applicable pump power: ≤ 11KW (for higher-power pumps, an additional starter cabinet is required)

2. Operating voltage: 380V ± 10%

3. RF card: Compliant with ISO/IEC14443A protocol, 32-bit unique serial number

4. Operating frequency: 13.56MHz; communication rate: 106 KBPS; sensing distance: ≤ 10cm

5. Unit price setting: Accurate to two decimal places (0.00 currency unit)

6. Display: Chinese character LCD display; maximum recharge display: 8 digits (999,999.99)
   ⚠️ Do not open the cover while powered on.

III. Functional Features of the Well Irrigation Controller

1. Tiered water pricing – Supports three-level, four-tier water pricing plus electricity pricing, enabling progressive pricing to meet agricultural water pricing reform requirements.

2. Flexible metering configuration – Supports water‑only/electricity‑only or dual metering, single‑control/dual‑control, unit price setting, and tiered water pricing, all configurable to meet various metering and control needs.

3. Multi‑card/multi‑well flexibility – Supports multiple cards per well, one card for multiple wells, or well‑specific authorization cards (for 1–30 households per well).

4. Card‑controlled pump start/stop – Tap the card to start or stop the pump; the system automatically meters and deducts charges according to the preset unit price.

5. Comprehensive protection – Includes motor phase‑loss protection, overload protection, and short‑circuit protection.

6. Electricity‑to‑water conversion – Calculates and displays water consumption based on electricity usage using a preset water‑electricity coefficient, eliminating the need for a separate flow meter.

7. LCD display – Shows total water consumption, total water cost, total electricity consumption, total electricity cost, and water quota utilization percentage in Chinese characters.

8. Configurable low‑balance alert – Helps users monitor water usage and recharge in time without interrupting operation.

9. Smart card identification – Automatically identifies illegal or counterfeit cards to prevent management loopholes.

10. Historical record function – Supports balance inquiry for lost cards, replacement card issuance, and invalidation of reported lost cards to prevent fraudulent use.

11. Unsettled card reminder on startup – Displays a reminder if a previous user's card was not properly settled, facilitating management for both users and administrators.

12. Balance inquiry during operation – While one user is operating the device, other users can tap their cards to check their own balance without affecting the current user's operation.

13. Anti‑theft protection (bypass prevention) – Detects electricity or water theft and automatically cuts off the high‑voltage power supply upon detection. (Note: Requires the installation of a synchronous smart power management box.)

14. Remote data transmission – Supports (with optional communication module) real‑time transmission of water usage data and well extraction data.

15. Local & remote control – Supports local control and, with the communication module, remote on/off control via mobile APP or PC.

16. Remote parameter setting – Supports (with communication module) remote configuration of water quotas, water prices, and other parameters.

17. Enclosed ABS casing – Splash‑proof, dust‑proof, and insect‑proof for reliable outdoor use.

IV. Functional Features of the System Management Unit

1. PC version – Runs on Windows operating system with a Chinese graphical interface and a large‑capacity database.

2. Standalone version – Operates without a computer, with Chinese character prompts for easy operation.

3. Large‑scale management – Manages up to 50,000 well irrigation controllers and issues/ manages up to 50,000 RF cards.

4. Village code locking – The village code cannot be changed, preventing cross‑village recharge management issues.

5. Pulse constant locking – The pulse constant cannot be altered, avoiding metering inaccuracies due to accidental changes.

6. Recharge statistics – Provides recharge amount statistics for clear account management, preventing misappropriation by administrators or operators.

7. Two‑level authority management – Clearly distinguishes between administrator and operator permissions; operators have usage rights only.

8. Password recovery function – Allows administrators to recover forgotten passwords without affecting system operation, maximizing user‑friendliness.
