This helps to ensure the rationality and adaptability of the verification period.
Consider the actual situation: the calculation of the second verification period compensation factor takes into account the variation of the time interval and the floating of the data amount in the history data. This allows the system to adapt better to the actual situation, not just to the theoretical time interval.
Maximum time interval considerations: by taking into account the maximum value of the time interval (Tmax) that occurs in the received substation environment temperature and humidity characterization data, the system ensures that the second verification period is not too short to cope with larger time intervals.
The verification accuracy is improved: by calculating the second verification period using the actual time interval of the history data and the data amount float, the system can improve the accuracy of verification, thereby better ensuring the reliability of the data.
