The IC card prepaid system is a comprehensive management system that integrates remote data collection and IC card business management. The system mainly includes modules such as file management, IC business management, data collection, anomaly management, and statistical analysis. Implement functions such as IC card recharge, data collection, data monitoring, anomaly management, and energy consumption analysis. Forming a virtuous cycle of paying first and then using heat can solve the problems of low efficiency in traditional charging models and avoid malicious arrears, achieving remote collection of heating data and intelligent control of charging.

IC card prepaid system software functions:

1. System parameters: Set relevant system parameters such as unit name, installation time, whether to activate alarms, SMS alarm settings, and whether to activate automatic monitoring.

2. User settings: mainly used for adding and deleting hot users, prepaid users can also remotely set or read controller parameters.

3. Heating control: managing valve opening, user recharge, IC card management.

4. Report printing: Users can choose to print historical data reports, real-time reports, monthly reports, daily reports, recharge reports, and valve control reports.

5. Alarm processing: Users can view alarm information, turn off alarm sounds, and turn off alarm lights.

6. Data curve: Users can view real-time and historical curves of "temperature", "pressure", and "instantaneous flow", and also print the screen curve of this window.

7. Calculation: Mainly responsible for calculating pipeline losses.

8. Operation permission management: Users can add and delete users, and modify operator basic information. You can change the current user's login password. You can switch login personnel.

The IC card prepayment system is a data transmission network that receives measurement data from a steam metering system and outputs and receives various digital quantities through a serial port at regular intervals to supply users. At the same time, the system uses a microcontroller as the core to realize the IC card prepayment function, which is called "pay first, use steam later". The system combines valve control circuits with electric control valves to form a closed-loop control system, suitable for trade settlement. It is mainly used for energy billing applications in industries such as power automation, industrial monitoring, agriculture, oil fields, water conservancy, and heat. The GPRS network platform can be used to achieve multi center transmission of data information, remote measurement and control, and alarm.
