Patent ID: 7437208

Claim:
A method for the computer-aided measurement of at least one of quality and process data during one of production and conversion of a fiber material web, comprising the steps of: correlating raw measured data with target data, said raw measured data being present in the form of other quality and process data gathered during one of the production and the conversion of the material web, said correlation including at least one of: incorporating measurements of quality parameters in a laboratory with said raw measured data; and combining portions of said raw measured data to form data sets, which are determined simultaneously; running at least one soft-sensor algorithm in a computer-based operation and linking unit; selecting specific laboratory or quality measurements to serve as target data, which by way of said soft-sensor algorithm is calculated from said other quality and process data serving as input data, each said data set containing measured data, which relates approximately to a monitored volume of the material web and raw material; pre-filtering items and data; and coordinating said items of data with one another taking into account an accuracy with which a simultaneity of said data sets are known.
