Problems solved by technology

Consequently, the gains from measuring operating parameters are sometimes not improved but worsened in the error monitoring of the plant, since in difficult cases, for example, important operating parameter values ​​can be hidden among a large number of other operating parameter values ​​and thus can no longer be interpreted
[0003] Therefore, it is very complicated in prior art solutions to accurately detect the equipment state from multiple sensed operating parameters
In addition, it is also difficult to find the cause of the error state in the prior art due to the sometimes complex relationship

Embodiment Construction

[0072] figure 1 A schematic block diagram of a system 100 for determining a state of a device 200 is shown. In particular, the device 200 can be an electric machine, such as an electric motor and / or a generator. Alternatively, device 200 can also be a pump or a drive train of a vehicle, for example an electric or hybrid vehicle.

[0073] Although system 100 and device 200 are in figure 1 Shown separately from each other in , in several embodiments the device 200 can include the system 100 for determining the state of the device 200 . According to the invention, a vehicle comprising the system 100 and the device 200 can also be proposed.

[0074] System 100 is explained in more detail below using an electric motor as device 200 , wherein the embodiment described is not restricted to such a device 200 .

[0075] The system 100 comprises a detection device 10 designed to detect at least two operating parameters of the installation 200 during operation of the installation. Fo...

Abstract

The invention relates to a system and to a method for determining a state of a device by means of a trained support-vector machine. According to the invention, an operating parameter space is dividedinto classification volumes, at least one of which indicates a normal state and at least one other of which indicates a fault state of the device. A current state of the device can therefore be determined by determining where a current operating parameter point is to be arranged in the operating parameter space. The invention further relates to methods and to variants of the system in order to facilitate a cause evaluation and to determine particularly relevant operating parameters for the fault determination.

Description

Background technique [0001] Modern equipment is often equipped with multiple sensors capable of detecting various operating parameters of the equipment before, after or during its operation. Certain permutations of operating parameters can under certain circumstances indicate that the device is in a normal state or conversely indicate that the device is in an error state. [0002] In the case of a large number of operating parameters, the sometimes complex relationship between the operating parameters that can cause an error state is often not clear. Therefore, sometimes the gains from measuring operating parameters are not improved error monitoring of the plant, but rather worsened, since in difficult cases, for example, important operating parameter values ​​can be hidden among numerous other operating parameter values ​​and thus can no longer be interpreted. [0003] It is therefore very complicated in prior art solutions to accurately detect the plant state from a plurali...
