Solution Overview
Problem
Existing methods for detecting asynchronous data in real-time systems are inadequate due to their deterministic nature, which fails to accurately handle probabilistic behaviors caused by factors like transport delays and traffic congestion.
Innovation Solution
A probabilistic approach using a recursive estimator and Mahalanobis distance to determine the synchronicity of data with the system clock, allowing for online adaptation to changing system conditions and robust outlier detection.

1Measurement precision
If deterministic methods are used to detect asynchronous data by comparing time differences with predefined thresholds, then the detection process is simple and fast, but the accuracy is insufficient due to the probabilistic nature of asynchronous data occurrence
Solution Approach 1:
The patent changes the detection parameters from fixed deterministic thresholds to adaptive probabilistic parameters. The system estimates the standard deviation of time differences online and dynamically adjusts the threshold based on statistical properties, transforming the detection method from static to adaptive, thereby improving accuracy while managing complexity through algorithmic optimization
Solution Approach 2:
The patent replaces the mechanical deterministic threshold comparison with a statistical probabilistic model. Instead of using fixed mechanical thresholds, the system employs statistical estimation of time difference distributions and uses Mahalanobis distance or statistical hypothesis testing to detect asynchronous data, substituting rigid mechanical rules with flexible statistical methods
2Measurement precision
If the detection threshold is set to be highly sensitive to detect all asynchronous data, then the detection accuracy improves, but the false positive rate increases causing legitimate data to be rejected
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors the statistical properties of time differences and adjusts detection thresholds based on observed data patterns. The online estimation of standard deviation and adaptive threshold adjustment create a feedback loop that balances detection sensitivity with false positive control, improving both accuracy and reliability simultaneously
Solution Approach 2:
The patent transforms the static detection threshold into a dynamic parameter that adapts to changing system conditions. The threshold is no longer fixed but evolves based on real-time statistical analysis of time difference distributions, allowing the system to maintain optimal detection performance under varying communication conditions while minimizing false rejections
