Abstract

A machine classifier classifies signals of an industrial plant and determines a current state as a result. On the basis of the current state, an audio profile is selected from a number of audio profiles and issued in the form of a synthetically generated acoustic signal to a plant operator. For that purpose, the state of the industrial plant is continuously evaluated and, for example, with the aid of a MIDI sequencer, is used to manipulate different tracks of a piece of music or of synthetically generated artificial background noise. In this way, the plant operator is able to discern intuitively, and optionally even subliminally, divergences from a normal operation of the industrial plant, which can only be communicated to the operator via the overloaded visual channel with great difficulty, or not at all. The plant operator can therefore learn of the state of the industrial plant via the auditory sense or learn that in certain situations the industrial plant does not sound right. Since for that purpose use is made of a comparatively underused sensory channel with the acoustic perception, even small changes in the acoustic signal produce a high level of alertness in the plant operator.

Claims

1. A method for the acoustic representation of states of an industrial plant,

processing signals of the industrial plant using a machine classifier to determine current state of the industrial plant,

based on the determined current stated of the industrial plant, selecting an audio profile from a number of audio profiles using a computer,

converting the audio profile into an acoustic signal, and

outputting the acoustic signal to a plant operator.

2. The method of claim 1, wherein the machine classifier is one of a program of a plant automation system, an expert system, a neural network, and a support vector machine.

3. The method of claim 1,

wherein the signals are obtained from over a thousand different sources,

wherein prior to or during the processing with the machine classifier, the signals are at least one of filtered, weighted, aggregated, and abstracted, and

wherein, apart from the signals, the machine classifier processes at least one of signal trends, key performance indicators, and data from at least one of a production control system, a corporate resource planning system, a system for production planning and control, and archiving.

4. The method of claim 1, wherein the current state is one of a normal operation state, a start-up state, a shut-down state, a ready state, an idle state, and a malfunction state of the industrial plant.

5. The method of claim 1, wherein the audio profiles are standardized from the number of audio profiles.

6. The method of claim 1, wherein the industrial plant is a power station or a factory.

7. The method of claim 1, wherein the audio profile has an interface via which profile parameters of the audio profile are configurable according to the current state.

8. The of claim 1,

wherein the acoustic signal is assembled from a plurality of tracks which are synthetically generated with the aid of a sequencer, and

wherein each track of the acoustic signal is influenced by a profile parameter of the audio profile.

9. The method of claim 1, wherein the acoustic signal is one of a noise, a noise in conjunction with a signal tone, a noise in conjunction with a parameter-dependent tone, a constant background noise, and a piece of music.

10. The method of claim 1, wherein the tracks form a score of a piece of music as the acoustic signal.

11. The method of claim 1, wherein the acoustic signal is generated by synthesized sound or sampling.
