A steel plate position tracking control system and method for a medium-thick plate heat treatment furnace

Abstract

The invention discloses a system and method for tracking and controlling the position of a steel plate of a moderate-thickness plate thermal treatment furnace. The method comprises the steps of calculating the process running speed and running logic of the steel plate according to a heating curve formulated by a process control model, issuing the process running speed and the running logic to a roller frequency converter in the furnace for execution, feeding back the actual speed of the steel plate according to an encoder, precisely tracking the position of the steel plate in the furnace, correcting the tracking position of the steel plate according to trigger signals fed back by a detector in a tracking area, enabling the running logic of the steel plate to be safely interlocked with the furnace feeding and discharging operations, controlling swing of the steel plate in process segments of the thermal treatment furnace, calculating and controlling the safety distance of the steel plate in the thermal treatment furnace, implementing the safety anti-collision strategy, drawing a steel plate dynamic graphics on a production monitor terminal in real time, and displaying the position information, the process information and the speed information of the steel plate in real time. According to the system and method, the difficult problems of precise tracking, speed control, safe interlocking, anti-collision control and the like of a moderate-thickness plate in the thermal treatment furnace can be solved well.

Description

technical field [0001] The invention relates to the field of heat treatment production control of medium and thick plates, in particular to a system and method for tracking and controlling the steel plate position of a heat treatment furnace for medium and heavy plates. Background technique [0002] The heat treatment production of medium and thick plates is characterized by strong continuity, fast speed and complex control. As an important link in the automatic control of the heat treatment production line, the position tracking function in the steel plate heat treatment furnace can track the position of the steel plate in the furnace in real time, and implement the safety interlock control of the steel plate movement , the dynamic information of steel plate position and process information are displayed on the human-computer interaction interface, which is convenient for operators to grasp the position and operation of medium and thick plates in the furnace in real time, an...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the existing steel plate position tracking control methods for medium and heavy plate heat treatment furnaces are either too simple, or are only devoted to the development of methods to improve the accuracy of steel plate position tracking. There is no systematic and effective method for the chain of discharge, human-computer interaction, etc.
