I. Fundamental Field Integrity Verification
Complete Record Comparison: Export all RC calibration records within the synchronisation time window in both MES and SCADA, ensuring that the total number of records is entirely consistent, with no missing or duplicate entries.
Core Field Verification: Verify that the values on both sides are identical by comparing each key field, including RC capacitance, filter cutoff frequency, temperature fluctuation, calibration timestamp, and operator.
Verification of Timestamp Continuity: Ensure that the timestamps of all RC calibration data are uninterrupted and that the record time nodes are connected seamlessly before and after the synchronisation interruption, with no timestamp errors.
II. Verification of Data Accuracy Compliance
Benchmark Parameter Matching Verification: The process qualification standards are met when the deviation between the measured RC capacitance value and the preset benchmark file in the MES system is ≤5%. Randomly select at least 10% of the RC calibration records for testing.
Verification of Precision Digit Alignment: Ensure that the decimal places and units of the RC calibration data on both sides are consistently maintained, with no deviations, such as automatic rounding on the MES side and the retention of original precision on the SCADA side.
Generate a unified hash verification value for all RC calibration data from both parties for cross-system hash value verification. The absence of any tampering or deviation from the entire data is demonstrated by the presence of completely identical hash values.
III. Verification of the Link Synchronisation Function Reproduction
Single Data Synchronisation Test: Conduct an on-site RC calibration operation. Verify that the SCADA data is synchronised with the MES system within 100 milliseconds of acquisition, without any delay or corrupted characters.
Multi-machine Concurrent Synchronisation Test: Trigger RC calibration duties on three machines simultaneously. Confirm that concurrency conflicts do not result in data loss during bidirectional synchronisation of all data.
Breakpoint Resume Function Verification: Disconnect the network manually for 10 minutes and subsequently reconnect it. Verify that the RC calibration data that was interrupted can be automatically retransmitted without any data loss on either end.
IV. Closed-Loop Verification for Traceability and Compliance
Operation Log Consistency Verification: Ensure that the permission locking and unlocking of RC calibration tasks in both systems are entirely consistent, with no missing logs or misaligned records.
Verification of Linked Data: Ensuring the traceability of the impact of RC parameters on product quality by verifying that the RC calibration data is accurately correlated with the corresponding production work orders and product yield data for the specified time period.
Audit Export Verification: Exports RC calibration data reports from MES and SCADA, respectively, ensuring that the report content is consistent and that the quality system audit requirements of the precision injection moulding industry are met.
Ensuring 100% consistency of manually restored RC calibration data and averting deviations in subsequent data traceability and process judgement, the entire verification process can be completed within 30 minutes.
