A method for the detection of interference sources or of faulty measuring sensors by good case - modeling and partial masking of equations

摘要

The present invention relates to a method for monitoring and fault diagnosis of a complex technical system as a whole.The present invention is characterized by setting up of a total system model equation, consisting of parameters of the invention, in which the model equations of the overall system in the form of the individual components, detecting the parameters of the individual components by means of sensor values of the individual components assigned sensors, establishing whether an adaptation of the parameters to the sensor values is possible, and the total system model equation is detachable from. Upon detecting that an adaptation of at least one parameter to a sensor value is not possible and the total system model equation cannot be solved for fault diagnosis takes place as an alternative or in addition a masking of respective components and / or measuring sensors associated model equations or meodellgleichungsbestandteilen from the total system model equation, until an adaptation of the remaining parameters to the remaining sensor values is possible, and the remaining total system model equation can be detached again, including detecting the respective components and / or measuring sensors as defective.
