| 摘要 |
The invention relates to a method for fault localization and diagnosis in a fluidic installation, wherein the fluidic volume flow of the overall installation, or of at least a partial region of the same, and the fluid pressure (P) are each recorded during an operating cycle and compared to stored references. At the time of a variation or change of the variation from the reference, it is determined on which component or components (10-14) of the installation a process influencing the fluid consumption has taken place in order to then identify the same as faulty. Conductance variables (Q/P) are formed from the respective volume flow values (Q) and the measured pressure (P) and are integrated or added together throughout the operating cycle to form conductance values (K), wherein a corresponding conductance reference curve is selected as a reference from a stored selection matrix, which comprises the conductance reference curves, or time-dependent conductance values, for various operating states.
