Benefits of technology

[0010]In a further embodiment of the present invention, an article comprising one or more machine-readable storage media containing instructions is provided for fault detection and classification based on calculating distances between data points. The one or more instructions, when executed, enable the processor to receive a data sample representative of measurements of variables that are associated with a process operation, perform principal component analysis on the data sample

Problems solved by technology

Analyzing large amounts of collected data, however, poses a challenge because of the processing power or resources that are required to process the data, possibly within a specified amount of time.
Because of limited processing capabilities and/or time constraints, users often times choose and analyze only a selective subset of variables that are consi

Embodiment Construction

[0019]Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

[0020]Turning now to the drawings, and specifically referring to FIG. 1, a block diagram of a system 100 is illustrated, in accordance with one embodiment of the present invention. The system 100 in the illustrated embodiment is capable of performing an industrial process, such as a

Abstract

A method and apparatus is provided for fault detection and classification based on calculating distances between data points. The method comprises receiving a data sample representative of measurements of one or more variables associated with a process operation, determining a distance between the data sample and one or more data points of a history data of the process operation and detecting a fault associated with the process operation based on the distance between the data sample and the one or more data points of the history data.
