AI Technical Summary
Existing technologies cannot adapt to full snapshot transmission mode, making it difficult to distinguish between data anomalies and device status anomalies, and data quality issues exist in cross-security partition transmission.
The system adopts a periodic full-snapshot transmission mode, and performs batch data integrity verification, single-point basic quality verification, time series correlation analysis, and comprehensive judgment of anomaly sources through unified time information, combined with cross-regional transmission probes for quality assessment.
It enables accurate identification of communication interruptions and abnormal device status in full snapshot transmission mode, reduces redundant alarms, improves the accuracy and efficiency of data quality assessment, and supports rapid location of transmission problems.
