Abstract
In order to provide a method for predicting process deviations in an industrial-method plant, for example a painting plant, by means of which process deviations are predictable simply and reliably, it is proposed according to the invention that the method should comprise the following: automatic generation of a prediction model; prediction of process deviations during operation of the industrial-method plant, using the prediction model.
Claims19
A method for predicting process deviations in an industrial-method plant, the method comprising:
- automatically generating a prediction model, wherein, for generating the prediction model, process values and/or status variables measured by a sensor are stored during operation of the industrial-method plant for a predetermined period, and wherein the predetermined period for which process values and/or status variables are stored during operation of the industrial-method plant is predetermined in dependence at least one of:
- (i) the industrial-method plant is in an operation-ready state, in particular for a production operation, for at least 60% of the predetermined period,
- (ii) the industrial-method plant is in a production-ready state for at least 60% of the predetermined period,
- (iii) a predetermined number of process deviations and/or disruptions in the predetermined period;
- and
- predicting process deviations during operation of the industrial-method plant, using the prediction model, wherein the method for predicting process deviations is carried out in an industrial supply air plant, a pre-treatment station, a station for cathodic dip coating and/or a drying station.
A system for predicting process deviations in an industrial-method plant, the system comprising:
- a sensor to measure a process value;
- and
- an industrial controller to:
- generate a prediction model, wherein to generate the prediction model, process values and/or status variables are stored during operation of the industrial-method plant for a predetermined period, and wherein the predetermined period for which process values and/or status variables are stored during operation of the industrial-method plant is predetermined in dependence at least one of:
- (i) the industrial-method plant is in an operation-ready state, for a production operation, of at least 60% of the predetermined period,
- (ii) the industrial-method plant is in a production-ready state for at least 60% of the predetermined period,
- (iii) a predetermined number of process deviations and/or disruptions in the predetermined period;
- and
- predict, based on the process value, process deviations during operation of the industrial-method plant, using the prediction model, wherein the system for predicting process deviations is carried out in an industrial supply air plant, a pre-treatment station, a station for cathodic dip coating and/or a drying station.
