AI Technical Summary

Technical Problem

Existing systems for tracking places on a material railway face challenges in identification accuracy due to production processes affecting identification positions or markings, leading to discrepancies between original and processed identification points or markings.

Method used

A procedure that involves recording measurement data of surface areas on a material railway using detection devices, editing the material track, and re-identifying surface areas using the recorded measurement data and times to improve identification accuracy and account for spatial and temporal changes.

Benefits of technology

The procedure enhances the identification accuracy of surface areas on a material railway by utilizing measurement data and times to track changes and maintain precise identification even after processing, thereby improving tracking and tracing in production processes.

Abstract

The present invention relates to a method for tracking locations (w1, w2, w3) on a material web (120, 122, 124) during the processing of the material web (120, 122, 124), said method comprising the steps of: a) capturing first measurement data (300) of a first surface region (w1) of the material web (120) using a first capturing device (150) at a first point in time, b) capturing second measurement data of a second surface region (w2, w3) of the material web (120, 122, 124) using the first capturing device (150) at a second point in time later than the first point in time, c) processing the material web (120, 122, 124) in a process step, d) identifying the first surface region (s1) on the processed material web (124) using a second capturing device (160) as well as the first and / or second measurement data (300), e) identifying the second surface region (s5, s9) on the processed material web (124) using the second capturing device (160), the first and / or second measurement data (300), and the first and second points in time.
