Method for remotely capturing hot-rolled strip steel tracking signal

Abstract

The invention relates to a method for remotely capturing a hot-rolled strip steel tracking signal. The method mainly achieves the aim of real-time monitoring of a rolling line strip steel position signal on a hot rolling production management level computer system (MES). According to the technical scheme, the method comprises the steps of (1) collection of the strip steel tracking signal, wherein a strip steel specification from a process control system and tracking information of strip steel entering and getting out of rolling mill equipment and the like are collected on the MES in a telegraph text communication manner; (2) analysis of the strip steel tracking signal, wherein analysis processing is carried out on the collected tracking signal according to the strip steel specification and the position of the strip steel, and an effective tracking signal is stored in a fixed-length tracking signal table in a database by adopting a fixed tracking position as a keyword; and (3) monitoring of the strip steel tracking signal, wherein tracking signal change information in the database is monitored in real time on an MES client side, and therefore the position of the strip steel and the state of the rolling mill equipment are determined. According to the method, the collected data volume is small, and the foundation is laid for obtaining a strip steel tracking graph and achieving other monitoring applications on the MES.

Description

[0001] technical field [0002] The invention relates to a method for tracking hot-rolled steel strips, in particular to a method for remotely capturing hot-rolled strip tracking signals, and belongs to the technical field of metallurgical automation. Background technique [0003] The production of hot rolling line is characterized by strong continuity, fast speed and complex control. The production control is inseparable from the basic automatic control system (L1) and process control system (L2). In the L2 system, it is generally necessary to track parameters such as the position of the strip in real time, so as to make timely adjustments to the production process or start related control functions such as model setting calculations. L2 rolling line strip tracking is realized by directly collecting a large number of on-site position, speed and other sensor information through L1. There are as many as tens of thousands of sampling points, and the sampling frequency is gene...
