Machine diagnosis system
First Claim
1. Machine diagnosis system for state-oriented operation monitoring of a machine, comprising:
- a characteristic value module which, proceeding from machine state-related measurement values, forms diagnosis-relevant characteristic values that are linked to operating parameters; and
a cause module which, from the characteristic values, diagnoses a cause for the detected measurement values,wherein the cause module, for at least one possible cause in each case, calculates a cause probability with the aid of at least one probability-characteristic value relation described by a polygonal course, which indicates with what probability the corresponding cause is responsible for the presence of the detected measurement values.

Abstract
The invention, that relates to a machine diagnosis system for the state-oriented operation monitoring of a machine, comprises a characteristic value module and a cause module. The characteristic value module, proceeding from machine-state referred measurement values, establishes diagnosis-relevant characteristic values, and the cause module diagnoses from the characteristic values a cause for the detected measurement values. There the cause module calculates for at least one possible cause in each case a cause probability which indicates with what probability the corresponding cause is responsible for the presence of the detected oscillation measurement values.
