Abstract (en)
[origin: US6556957B1] A method for detection an alarm state of measurement signal values received by means for detecting measurement values, wherein an alarm state is triggered when for a currently received measurement signal value at least one pre-set limit value is exceeded, has a faster recognition of an alarm situation and at the same time a lower rate of false alarms when in a first step for measurement signal values which are subsequent in time their position parameter (2) and a corresponding deviation parameter (3) of the measurement signal values from the position parameter is calculated in an adjustable time window, wherein in a second step each further subsequent measurement signal value is compared to the position parameter (2) an weighted with the deviation parameter (3) in order to obtain a respective evaluation quantity, and wherein in a third step an outlier state (6) is detected when the evaluation quantity exceeds an adjustable outlier parameter, whereas an alarm state (8) indicating the presence of a significant drift or jump of the measurement signal values is detected when the evaluation quantity exceeds an adjustable alarm parameter.
