A method for detecting of systematic errors are, in particular for the automatic disruption recognition in the case of quality control, by means of measuring devices equipped with measuring sensors

摘要

The invention concerns a method of detecting systematic defects, in particular for automatically detecting malfunctions in quality control processes, by means of measuring apparatus equipped with measuring sensors and with a combination of three individual sensors of the same type for parallel measurements on the same object. The measured values of the individual sensors are detected and the mean value and/or a comparative value of the measured values of the individual sensors is calculated. The deviations of the at least three individual sensors from the common mean value and/or the deviations in the comparative values of the individual sensors are determined. The mean value and/or comparative value and/or the mean value deviations and/or comparative value deviations are compared with one another during a sequence of measurements carried out at various measuring locations on a given object among an amount of identical objects or on an amount of identical objects, so that defects in the measuring apparatus can simultaneously be detected and the quality of the objects can be controlled.
