Portable and movable near-control operating device and control method for leveling line coiling area

Abstract

The invention discloses a portable intelligent synchronous close-control device and its control method for the coiling area of ​​the leveling line. Panel, the intelligent remote control operation panel includes a touch screen, a remote control operating system, an NFC module, and a communication port. The HMI operation screen of the operation buttons that control the equipment in the coiling area is displayed on the touch screen. The operation sends the corresponding control signal to S7 PLC, and S7 PLC performs operation control on the coiler, exit guide roller and tension roller device according to the control signal. The invention overcomes the disadvantages of the existing fixed on-site close-control operation box, such as large volume, blocking sight line, large wiring project, and unchangeable operation interface.

Description

technical field [0001] The invention relates to the field of operation control of a hot rolling finishing line, and more particularly, to a portable intelligent synchronous short-range control device and a control method thereof for the coiling area of ​​a leveling line. Background technique [0002] In iron and steel enterprises at home and abroad, the flattening line coiling area is mainly composed of tension device, exit guide roll, tail roll, coiler and other equipment. The purpose is to rewind the strip after the flattening process into Coil. With the improvement of current automation and intelligent control technology, the rolling process control in the coiling area has been changed from the original manual control to semi-automatic control, but in order to deal with abnormalities (such as rolling mill roll surface population cleaning, etc.) The manual proximity operation function is essential, so the electrical control of the equipment in the coiling area of ​​the fl...

AI Technical Summary

Problems solved by technology

[0005] 1. The volume of the operation box is large, the equipment of the automatic operation line is compact, the layout of the operation box is relatively difficult, and it is easy to block the sight of the operators in the main control room

[0006] 2. On the operation box, there are many operation buttons and switches, the amount of cables is relatively large, and the engineering volume of wiring is correspondingly high

[0007] 3. There are many IO modules in the PLC. In the traditional operation line, the operation buttons of the close control operation box occupy about 1 / 3 of the IO points of the PLC.

[0008] 4. Pay attention to manual operation, and the operation status display is weak. If a more complete status display is required, an operation panel such as OP needs to be added. The cost is high and the volume of the operation box will be larger

[0009] 5. Function extension is almost impossible

Once the design, manufacture and installation of the remote control operation box is completed, it needs to be replaced if it needs to be expanded.
