Abstract

A workflow for continuity of data from sensors in the monitoring system, automatically identifying abnormal sensors. Using a sensor model For each sensor Approximate values from sensors In order for the unit to detect the malfunction Take the estimate from Sensor model Let's find the relationship, standard deviation. And the mean of each data Sensor model with sensor data And then analyzed the change in value Relationship of individual model data to sensor data. When the calculated value is lower than the value Acceptable, an outlier estimation model is assumed. In which case the data correlation between When the deviation results on the standard And the mean of the sensor data and the data from the model is too different. Acceptable value Shows that the model estimates the outlier. In the event that the model is identified as faulty, the processor calculates the faulty sensor. And take data from the sensor model that has correlation Of the best information To replace the unusual sensor information
