JPS54149355A - Continuous gathering method for data of rolled material - Google Patents

Abstract

PURPOSE: To make possible the high accurate quality, the control for production, etc., at the finishing pass, by interrupting the computer with the pulse generated in the pulse generator connected to the final stand, for every count of previously settled number of pulse, on purpose to gather the data of the rolled material.

CONSTITUTION: The rolling work is started, and the rotary pulse of the finishing mill is counted by the pulse counter-comparator 40; when the overflow is detected, the signal is inputted to the A/D conversion-command unit 33, and the interruption signal for renewing the data-address is generated in the data-memory 35. At the same time, the signal from the unit 33 is also inputted to the A/D converter 36, which then generates the trigger signal for giving the memorizing order to the memory 35. Thus, so far as the memory capacity permits, the data of actual measurements for the process are memorized in the memory 35; if the memory causes overflow, the interruption signal is sent to the CPU 42, and whole of the memory contents gathered until then are channeled to the data channel-registor 34; hereby, the memory 35 has spare capacity. According to this method, whole of data of actual measurements for the temperature, breadth, thickness, etc., of the sheet, are gathered at a specified pitch, and the accuracy of the data analysis is improved.
