A new approach to data logging and on-line quality control for an electrolytic tin-plate production line

Abstract

The authors present a novel approach to the problem of data logging and online quality control in an electrolytic tin production line. The main functions realized by the system are: tracking (supervision) of the manufacturing process of the coils, simulation of drains in defective coils in order to improve their final quality, and consulting of data from coils previously manufactured. All these functions are realized online concurrently with data capturing. The application is of a low-cost type, running on an IBM-XT compatible computer under the MS-DOS operating system and mainly developed in Pascal. This system was installed in the ENSIDESA-Aviles factory in July 1988, and has performed continuously since then without any problems.<>
