Embodiment Construction

[0042] figure 1 shows an example of a time profile V of facility data D divided into time windows T of different lengths 1 , T 2 , T 3 . The plant data D preferably correspond to at least one measured and / or controlled variable of a process technology plant plotted over time. The facility data D characterizes the status of the facility, eg normal operation or one of possible faulty operations. In this case, the temporal profile V of the installation data D can characterize the installation state of the installation, for example at a point in time t. In particular, the curve V can characterize the dynamics on which the plant switches from one plant state to another or remains in the same state.

[0043] The temporal profile V of the installation data D can accordingly be used to carry out a classification of the installation state by means of the model. Here, preferably the time window T 1 , T 2 , T 3 One of them is associated with the model, that is, the respective as...

Abstract

The invention relates to a diagnostic method (1) and a diagnostic system (50) for a technical installation (10) and to a training method (100) for such a diagnostic system (50). A time curve (V) of the installation data (D) at least partially characterizing the installation state is provided, and the installation state is classified by means of at least two models on the basis of the time curve (V) of the installation data (D). Here, the models differ in terms of time windows (T1, T2, T3), on the basis of installation data from the time windows. A confidence is associated with the classifications derived from the at least two models, respectively. Additionally, diagnostic information based on the classification of the facility state and the confidence associated therewith is output.

Description

technical field [0001] The invention relates to a diagnostic method and a diagnostic system for process engineering installations as well as a training method for such a diagnostic system. Background technique [0002] In process technology installations, for example, materials are changed in terms of composition, type or properties, process technology installations such as refineries or factories can have extremely complex structures. A plant can, for example, consist of a plurality of components, possibly networked with one another and / or interrelated, ie for example valves, sensors, actuators and / or the like. Such installations are usually guided by a dedicated, in particular computer-based or at least computer-assisted process control system, which can take into account, in particular, the technological dependencies between the various components. Such process control systems include automation technology, in particular automation programs as well as operating and monit...
