Methods and mechanisms to perform maintenance event diagnostics using data matching techniques

Abstract

A system configured to, in response to an occurrence of a corrective maintenance event, obtain first sensor data pertaining to a first process run and second sensor data pertaining to a second process run. Responsive to determining that a comparison of the first sensor data and the second sensor data fails to satisfy a first threshold criterion, the system generates a first normalized dataset based on the first sensor data and a second normalized dataset based on the second sensor data. The system then generates trace matching data by performing a trace matching operation on the first normalized dataset and the second normalized dataset. Responsive to determining that the trace matching data satisfies a second threshold criterion, the system identifies a set of sensors associated with the first sensor data as the cause of the fault that triggered the corrective maintenance event.
