Abstract
An example data assessment method for a diagnostic system includes receiving a set of initialization data, analyzing the set of initialization data to identify a data outlier in the set of initialization data, and determining whether the set of initialization data is bimodal. The method further includes establishing a set of cleaned data based on the analysis and establishing a baseline operating condition for the device using the set of cleaned data.
Claims17
A data assessment method for a diagnostic system comprising:
- (a) receiving a set of initialization data;
- (b) identifying a data outlier in the set of initialization data;
- (c) determining whether the set of initialization data is bimodal;
- (d) establishing a set of cleaned data based on said step (b) and said step (c);
- and
- (e) establishing at least one baseline operating condition for a gas turbine engine device using the set of cleaned data established in said step (d).
A data assessment method for an engine diagnostic system comprising:
- (a) receiving initialization data from an engine assembly;
- (b) identifying outlying initialization data within the initialization data;
- (c) determining if the initialization data has multiple modes;
- (d) establishing a group of cleaned data by cleaning the group of initialization data based on said step (b) and said step (c), the cleaning including removing data from the group of data to establish a single mode;
- and
- (e) establishing a baseline operating condition of the engine assembly using the group of cleaned data.
A device diagnostic system comprising:
- a control module that receives a group of initialization data collected from a device and establishes a reference point for the device using at least a portion of the group of initialization data, wherein the control module is configured to remove initialization data from the group of initialization data to eliminate bimodality in the group of initialization data, wherein the control module if further configured to remove outlying initialization data from the group of initialization data.
