Abstract (en)

[origin: WO2013057085A1] A method for the preventive detection of failure in at least one apparatus to be monitored in a group comprising at least two apparatuses, the apparatus to be monitored comprising at least one first parameter correlated with at least one second parameter of at least one second apparatus of the group, said parameters representing status variables of said apparatus. The method comprises the following steps: predicting a value of the first parameter from a measured value of the second parameter; comparing the predicted value of the first parameter with a measured value of the first parameter; and analysing the result of the comparison made in the comparison step to detect a possibility of failure. The invention also relates to a computer program, a system and a module for the preventive detection of failure in an apparatus.
