2. Key Functional Modules

2.1 Library Center (Data Management Hub)

• Meter Library: Add, edit, remove, export (to Excel), or import (from Excel) meter data. A time-saving "batch input" function allows users to enter consecutive meter IDs by specifying only the start and end IDs (no need for one-by-one entry).
• Price Library: Create unlimited pricing plans, edit existing prices, or delete obsolete ones—supporting flexible tariff management for different meter types or user categories.
• Customer Library: Store and manage customer details (ID, name, address, phone, email) with unlimited entry capacity. Data can be exported/imported via Excel for easy bulk operations.
• District Library: Manage regional information (e.g., residential zones, industrial areas) to group meters and customers by location.
• Sales Station Library: Track sales outlets with customizable station IDs and location details, linking each station to specific districts.
• Account Library: Associate customer accounts with meters, sales stations, and tariff categories—providing a unified view of each user’s metering and billing data.

2.2 Top-up Center (Recharge Operations)

• Top-up by Amount: Select a meter, enter the recharge amount and currency (e.g., RMB, USD), choose a payment type (e.g., cash, e-card), and confirm. The system generates a receipt with a unique recharge TOKEN for meter activation.
• Top-up by Unit: Recharge based on usage units (e.g., cubic meters for water/gas). Enter the desired unit quantity, select a payment type, and confirm—again, a TOKEN-containing receipt is generated post-success.
• Refresh: Update the recharge page in real time to view the latest meter status or transaction data.

2.3 Advance Center (Troubleshooting & Reset)

• Clear Tamper: Resolve errors caused by meter tampering (e.g., electricity theft, unauthorized meter cover opening). Select the affected meter, and the system generates a tamper-clearing TOKEN via a receipt.
• Clear Tamper Record: View and export (to Excel) historical tamper-clearing logs, including customer ID, meter number, operator, TOKEN, and timestamp.
• Clear Credit: Reset the remaining balance in a meter (e.g., for account closure or adjustment). A unique TOKEN is generated to authorize the credit reset.
• Clear Credit Record: Track all credit-reset operations with exportable logs.

2.4 Reports Center (Data Analysis & Compliance)

• Receipt Report: Comprehensive recharge records (district, customer, meter ID, account ID, payment amount, TOKEN, operator, etc.).
• Monthly Summary Report: Monthly usage and payment data (total paid, VAT, excise duty, charge value, energy consumption).
• Customer Payment Report: Recharge history per sales station (total charges, number of transactions, payment type).
• Transaction Number Report: Query transaction IDs with linked customer, meter, and purchase details.
• District Report: Regional performance data (number of charges, cash/cheque/e-card payments, total revenue by district/sales station).
• Non-Vending Meter Report: Identify meters with no recharge activity within a user-defined time period (supports PDF/Excel export).

2.5 Account Management (User Access Control)

• Change Passwords: Update either the payment password (for recharge operations) or login password (for system access).
• Create Sub-Accounts: Generate unlimited sub-accounts with customized permissions (e.g., a "recharge-only" account for frontdesk staff). The process involves:
  1. Role Management: Define roles (e.g., "OnlyVending") and assign specific permissions (e.g., access to Top-up Center only).
  2. User Management: Create sub-accounts, link them to roles, and enter user details (ID, name, phone).
  3. Reset Password: Default sub-account password is set to "123456" (reminder: reset and secure passwords post-creation).

3. System Advantages

• High Operability: Intuitive interfaces and step-by-step workflows reduce training time for new users.
• Data Security: Leverages Microsoft SQL Server’s robust security features to protect sensitive customer and transaction data.
• Scalability: Supports unlimited entries for meters, customers, and prices—adapting to growing user bases or expanded service areas.
• Rich Query & Printing: All modules include search functions, and key operations (recharge, tamper clearing) generate printable receipts for compliance and user reference.
