Prepaid energy meters acting as front-end data acquisition terminals, are responsible for recording users’ electricity consumption data in real time. The prepaid system serving as a back-end management platform, handles core functions such as user account opening, recharge management, data analysis, and remote control. This deep integration brings the following advantages:

• Real-time uploading of electricity consumption data; the system automatically calculates fees and deducts any remaining balance.
• Support for 4G/Wi-Fi/LoRaWAN communication, enabling remote meter reading and control.
• Payment before use, effectively avoiding arrears.
• Automatic power cut-off when balance is insufficient; automatic power restoration after recharge.

In practical applications, this combination is widely used in power projects in industrial parks, commercial office buildings, residential buildings, student dormitories, and large shopping malls, and is particularly suitable for scenarios with dispersed electricity consumption and complex management.
