It mainly achieves real-time synchronization of "device status, user behavior, and operational data", with specific functions as follows:

I. Real-Time Display of Core Device Data (Visual Dashboard)

1. Individual power bank data: Displays current battery level, in-cabinet status, rental status, cell health, unique ID, affiliated cabinet location, etc.

2. Overall cabinet data: Shows slot occupancy, device online status, battery level of each power bank, network connection method, signal strength, etc.

3. Data update frequency: Core status (battery level, rental status) with latency ≤ 3 seconds; non-core data updated hourly, and manual refresh is also supported.

II. Data Display & Query Functions

1. Multi-dimensional filtering: Supports filtering by region, device number, and status to quickly locate key devices (e.g., "status of all power banks in a cabinet at a store in central London").

2. Data export & sharing: Exports to Excel/CSV formats, generating visual charts such as recent order & revenue status and device online rate line graphs.

3. Mobile adaptation: Supports login via mobile App and tablet, with a data dashboard that adapts to screen sizes for convenient on-site inspection.

III. Data Anomaly Alert Mechanism

1. Customizable notification settings: Set up alerts for custom abnormal scenarios (e.g., battery level below 20%, insufficient power banks in the cabinet, or cabinet fully occupied by returned power banks), triggering notifications via SMS, App push, and email.

2. Categorized labeling of abnormal data: Dashboard marks anomalies with three colors - red (malfunction), yellow (low battery), blue (offline); click to view detailed issue descriptions.

IV. Customizable Regional Data Adaptation

1. Compliant data storage: Store data on local servers in target markets (e.g., Poland for the EU) in accordance with GDPR and CCPA requirements.

2. Data privacy protection: Collect only data necessary for device operation, with user accounts and device data desensitized and separated.
