    摘要： Methods, systems, and computer program products are provided for implementing condition monitoring activities. Systems include a processor (204) in communication with a machine (202) being monitored. The processor (204) receives signals output by the machine (202) via a signal conversion element (210) associated with the machine (202). Systems also include a display device (205) in communication with the processor (204) for providing signatures of the signals received from the signal conversion element (210). Systems further include a means (204) for identifying, isolating, and capturing a signature (212) from the signatures presented on the display device (205). The systems also include a means (204) for digitizing and recording the signature (212) as an event kernel, normalizing the event kernel by performing a mean removal, and normalizing the energy to unity on results of the mean removal. Systems further include a storage device (206) for storing normalized event kernels.

    摘要： A system and method for monitoring the vibrations of a machine (110) that includes a reflective patch (130) affixed to the machine and a vibration detection module (120) including an interrogator unit (160) and a demodulation unit. The interrogator unit may be positioned remotely from the machine such that the interrogator unit transmits an electromagnetic beam to the reflective patch and reflected from the reflective patch to the demodulation unit. The demodulation unit demodulates the electromagnetic beam to determine the vibration of the machine.

    摘要： This invention provides a system (28) and method for generating alerts through multi-variate assessment. A normalizer (30) normalizes data obtained from a process. A classifier (32) classifies the correlated data in a multi-dimensional space defined for the variables in the process. The normalized data are classified into a normal cluster indicative of normal operating conditions and at least one alert cluster each indicative of alert conditions. An alert verifier (34) verifies correlated data classified as an alert condition. In another embodiment of this invention, a tracker is used for addressing drifting data sets that arise in the process over time which allows the adaptation of classifiers to the shifted state. In a third embodiment, the multi-variate generator is used in parallel with a trend performance analysis tool to validate alerts generated therefrom.

    摘要： This invention provides an improved alert generation system (20) and method for trend performance analysis. A multi-variate abnormal condition detector (28) normalizes data obtained from a process (16,17) and classifies the data in a multi-dimensional space defined for the variables in the process. The normalized data are classified into either a normal or abnormal class. An alert evaluator (29) evaluates the data classified in the abnormal class and determines whether the data are a true alert or a false alert. In another embodiment, the multi-variate abnormal condition detector (28) and alert evaluator (29) are used in parallel with a trend performance analysis tool to validate alerts generated therefrom.
