Abstract: Assistance apparatus for automatically identifying failure types of a technical system is provided including at least one processor configured to determine for each sensor data a set of specific temporal courses of first time series of the sensor data of the sensor and assign a symbolic representation to each of the different specific temporal courses, provide at least one failure pattern, obtain more than one monitored time series of sensor data of the technical system, each of them divided into a sequence of time segments, and automatically assign to each time segment a symbolic representations according to the temporal course of the sensor data in the time segment, calculate a similarity measure for the set of symbolic representations of a selected time interval, determine a ranking of the failure pattern depending on decreasing values of the calculated similarity measure, and output the ranking.

Abstract: A monitoring device including an analysing unit configured to obtain an actual sensor data point, determine whether the actual sensor data point is an outlier, determine whether the actual data point represents a discontinuity, determine a slope by a regression model of a slope equation of a straight line in time fitted to at least a predefined first number of subsequently obtained sensor data points, and determine whether the actual sensor data point belongs to the learned regression model, if the actual sensor data point does not belong to the learned regression model, determine a new slope based on the actual data point and a predefined second number of preceding sensor data points, and create a segment including all sensor data points, and display each sensor data point indicating the determined segment or being an outlier.

Abstract: An apparatus for monitoring an actuator system, a method for providing an apparatus for monitoring an actuator system, and a method for monitoring an actuator system where the has at least one actuator and at least one data output signal. An anomaly detector detects anomalies. A suppressing engine determines time periods in which a control intervention has been performed. In a resulting monitoring signal, only anomalies are indicated which do not overlap with time periods in which the control intervention has been performed resulting in less irrelevant alerts and false positives output to a human supervisor monitoring the actuator system. The apparatus for monitoring a system may be provided with a plurality of actuators that may affect one another over time. The apparatus may be applied to a system of submersible pumps, or a system of conveyor belts.
