- An assessment of a state of devices, ie of machines and / or systems, is usually based on the analysis of the temporal development of a wide variety of measured and / or characteristic quantities.
- a visualization technique of interest with which two different goals can be implemented at the same time, is of interest. On the one hand, it is desirable at a glance and without background knowledge the overall condition and / or to detect the trend and thus a temporal evolution of the overall state of a device. At the same time, however, it is also of interest to enable a clear and yet detailed view of the status and trends of individual assemblies and thus of components of the device up to the visualization of various characteristics of an assembly in order to be able to read comprehensive information about the damage in the event of damage ,

- the invention thus relates, inter alia, to a method for the clear presentation of multi-dimensional or high-dimensional feature vectors in the diagnostics of devices which, for example, can be designed as machines.
- Such feature vectors are represented by the characteristic values described above. This includes a general evaluation and / or representation of characteristic values or measured values, for example of state measurements on machines and components, which can be designed as roller bearings, by means of a vibration analysis.
- a clear representation of a multiplicity of characteristic values or measured values and their temporal trends or changes for the simple status detection of complex devices or systems is provided.
- the presentation can provide a quick overview of the condition. Furthermore, it is possible to analyze individual characteristic values or measured values in detail.
- the invention includes the introduction of a so-called. Globusdiagramms. This allows the display of a large number of characteristic values or measured values and their temporal trends.
- a hierarchy level is defined by the number of characteristic values shown in the globe diagrams. In a highest hierarchy level or level, only one characteristic value is displayed for only one component. Refinements of the hierarchy levels result from a larger number of characteristic values within the globe diagram. In this case, it is possible to represent a characteristic value for several components and / or several characteristic values for at least one component. The more characteristic values are considered, the finer or more accurate a state of a device formed from components can be represented. With this hierarchical form, among other things, the structure of a device is reflected.
- the device can have as components, for example, two bearings, wherein for each bearing several characteristic values can be monitored.
- the exemplary embodiment of the method described below relates to a visualization technique with which characteristic values are displayed as high-dimensional feature vectors in a hierarchy which can be easily detected by the user.
- An aspect of the invention comprises the application of a plurality of individual characteristics in a world map-like diagram, the so-called. Globusdiagramm, so that each degree of longitude of the globe diagram is associated with a characteristic value.
- the area around the north pole of the globe diagram is defined as a perfect state in this illustration.
- the area of the South Pole represents an advanced damage.
- the equatorial zone of the globe diagram can represent the area of incipient damage.
- the characteristic values are very close to one another in the region of the poles of the globe diagram. In the area of the equator, however, they have larger distances to each other. By means of this representation, a more differentiated consideration of the characteristic values is possible in the region of the equator, so that a first evaluation is provided for the user with this representation. If all characteristic values are arranged in the region of the north pole, ie the perfect region, it is not necessary to have a close look at the individual parameters. A change of individual characteristic values in the direction of the equator with the higher resolution present there can animate to a critical consideration of individual characteristic values.
- the mean value and the variance of a given state over a period of time to be determined are formed in the past and displayed as an ellipse around the current state.
- a clearer, less detailed view can be created by combining longitudes within the globe chart with appropriate weighting.
- z In the field of diagnosis of devices that are designed as machines, z.
- the characteristic values that relate to a particular bearing as a component are combined.
- This provides a superordinate longitude that describes the overall condition of the respective warehouse.
- This combination can also be carried out accordingly for all other components or parts of the device or machine to be monitored.
- the longitudes thus formed can in turn be combined with suitable weighting so that a single degree of longitude can stand for an ever greater number of components and / or characteristic values depending on the hierarchical level.
- the conclusion of the grouping is a single line at the highest level, on which the current state or the trend of the state of a complete device, eg machine, is displayed.
- the number of intermediate levels or hierarchy levels is arbitrary.
- Another aspect of this method involves the simultaneous display of different hierarchy levels.
- it makes sense to display for example, the refinement of the representation only for one degree of longitude, while the other degrees of longitude indicate higher-order hierarchy levels.
- the method is not only suitable for representing machine states. Typically, it is applicable wherever high-dimensional feature vectors are to be visualized and a meaningful hierarchical grouping of the individual components is possible through the characteristic values. Furthermore, in a refinement, a feature vector can define and / or represent a summary of a multiplicity of different characteristic values for a vector.
