Modifiable tracking control method for images of hot-rolled plate blanks

Abstract

The invention discloses a modifiable tracking control method for images of hot-rolled plate blanks, and belongs to the field of automatic control. The modifiable tracking control method includes that an automatic modification function module, a first manual correction module and a second manual correction module are added in a 'tracking' program of a PLC (programmable logic controller), and corresponding manual correction operation buttons are added to a human-machine interface of a terminal in a field; when a plate blank within a certain confidence interval is detected by a hot metal detector in the field, large correction cycle is started by the PLC if the current actual position of the plate blank is inconsistent with the position of an image, so that the image of the plate blank is automatically modified; when finding that the image of the plate blank is inconsistent with the actual position of the plate blank, operators in the field can select image areas required to be modified and image modification directions via the corresponding buttons on a picture of the human-machine interface of the terminal in the field, so that a manual image position modification function can be realized. The modifiable tracking control method has the advantages that the actual position of the plate blank can be accurately reflected, the hot-rolled plate blank tracking control precision is improved, a technological process can be controlled effectively, energy consumption is reduced, the quality of products is improved, and the modifiable tracking control method can be widely applied to the field of automatic control for hot-rolling production processes.

Description

technical field [0001] The invention belongs to the field of automatic control in the metal continuous casting process, in particular to a position tracking method for hot-rolled slabs. Background technique [0002] "Tracking" is one of the main functions of the computer system in the automatic control of the rolling process. [0003] In the production process, several pieces of steel strips are often processed in different processes on the production line at the same time, and the original conditions, processing conditions and finished product requirements of each piece of steel strip are different. [0004] In order to automatically control the entire rolling production process, it is necessary to strictly distinguish the different conditions of each strip, and to carry out corresponding automatic control in time according to their processing links and conditions on the production line. [0005] The "tracking" method is to determine the position and area of ​​the strip by...

Problems solved by technology

[0022] However, in the above-mentioned real-time tracking system of the existing strip steel position, all the calculation and display of the strip steel position are based on data calculation, and real-time modification or on-site correction cannot be performed. There is a deviation between the time and cannot be corrected or adjusted in time, which brings certain difficulties and inconvenience to the actual production process control or the adjustment of process parameters, and also affects the tracking control accuracy of the hot-rolled slab and the accuracy of the process control, seriously can also cause damage to the device
