摘要： A system for predicting events by associating time series data with other types of non-time series data can include a processor configured to receive a data stream including time series data transmitted from a sensor configured to measure an operating parameter of a component being monitored. The processor identifies sequences of interest in the time series data having predictive value. The processor compares the real-time data stream to a set of known historical patterns that act as effective leading indicators of different alarms and events. The processor extracts any identified sequences of interest from the time series data as an extracted event. The processor quantifies the relationship between the data of the extracted event and the known historical pattern by calculating a confidence level to denote a probability of occurrence of the event by comparing how closely the new time series data matches the data patterns associated with known events.

摘要： A fault detection and diagnosis for a gas turbine engine 12 comprises collecting a sensor signal from an acoustic or vibrational sensor 22 at the gas turbine engine, preprocessing the sensor signal to remove predictable background, and extracting a feature set from the sensor signal using Mel-Frequency Cepstral Coefficients (MFCC) algorithms and/or Code Excited Linear Prediction (CELP) algorithms. Fault and non-fault states are reported based on comparison the feature set and a library of fault and non-fault feature profile corresponding to fault and non-fault states of the gas turbine engine.

摘要： The present application relates to a method for determining multiple simultaneous fault conditions on complex systems. The method comprises receiving symptoms of a complex system from monitors. When some of the symptoms suggest the existence of multiple simultaneous fault conditions, then the method creates a symptom signature, creates one or more failure mode signatures, and creates an error code for each failure mode signature in regard to the symptom signature. Each failure mode signature is associated with only one failure mode. A Hamming distance is determined for each failure mode indicated as possibly causing the original fault condition. Each failure mode with the minimum Hamming distance and same Hamming Code are grouped together as being one of the multiple simultaneous fault conditions. All remaining failure modes with other Hamming distances are then assigned into one of the simultaneous fault conditions.

摘要： Monitoring of a system (10) is disclosed, in particular to identify the cause of conditions outside expected operating conditions. The output of one or more sensors (11,12,13) associated with a system (10) is monitored (40) and data from the one or more sensors is arranged (50) as a plurality of modes (101,102) with each mode being defined by a different condition in which the system may operate, such as different ambient conditions, variations in the physical configuration of the system and different operating conditions. Faulty conditions are identified (60) by monitored data being outside one of the plurality of modes. The use of a plurality of modes enables operation of the system to be defined and tracked more precisely so that operation of the system outside expected parameters may be detected more precisely and false alarms may be reduced. At least one of the modes may be established to indicate a particular failure of the system. This failure mode may have a likely cause of the failure associated with it such that diagnosis and repair may be facilitated quickly and easily.
摘要翻译：公开了对系统（10）的监视，特别是用于识别超出预期操作条件的条件的原因。监视与系统（10）相关联的一个或多个传感器（11,12,13）的输出（40），并且来自一个或多个传感器的数据被布置（50）为多个模式（101,102），每个模式由系统可操作的不同条件（例如不同的环境条件，系统的物理配置的变化和不同的操作条件）来定义。由多个模式之一的监视数据识别故障条件（60）。使用多种模式能够更精确地定义和跟踪系统的操作，使得可以更准确地检测出系统外部期望参数的操作，并且可以减少假警报。可以建立至少一种模式来指示系统的特定故障。该故障模式可能具有与其相关联的故障的可能原因，使得可以快速且容易地促进诊断和修复。

摘要： The invention relates to a method for analyzing a large number of messages (28), wherein the number of messages is reduced on the basis of pattern recognition (60) and pattern simplification (64), wherein rules for such pattern recognition (60) and pattern simplification (64) are based on a regular grammatical structure, and wherein patterns are sought in the remaining messages (28), or directly, that is, without previous simplification, wherein a syntactic pattern recognition (60) is used for each type of pattern search, and a finite machine can be derived using the regular grammatical structure underlying each pattern recognition (60) by transforming the mapping rules into transfer function, by means of which structural connections between the messages (28) can be displayed graphically.
