Portable intelligent synchronous near control device for hot rolling finishing operation line

Abstract

The invention discloses a portable intelligent synchronous near control device for a hot rolling finishing operation line. The device is in communication connection with an S7 PLC and comprises a plurality of industrial intelligent panel bases arranged beside each process area machine of the hot rolling finishing operation line and an industrial intelligent panel matched with any industrial intelligent panel base, wherein each industrial intelligent panel base comprises a base body, and an NFC identification card, an emergency stop switch and a key switch which are arranged on the base body; the industrial intelligent panel is provided with a touch screen, an NFC module and a communication interface, and an operating system is loaded in the industrial intelligent panel; the NFC identification cards are matched with the NFC module; and the emergency stop switches and the key switches are connected to the S7 PLC through hard wires. According to the portable intelligent synchronous near control device, the defects of large size, sight line blocking, large wiring project, high input and output module cost, incapability of changing an operation interface and the like of a fixed field near-control operation box beside a hot rolling finishing line machine in the prior art are overcome.

Description

technical field [0001] The invention relates to close-control operation equipment for a hot-rolling finishing line, and more specifically, to a portable intelligent synchronous close-control device for a hot-rolling finishing line. Background technique [0002] In iron and steel enterprises at home and abroad, the traditional manual close-control operation adopts the on-site operation mode, such as: in the entrance preparation station, uncoiling area, leveling area, roll changing area, coiling area, exit area, etc. Install a machine-side operation box respectively, and arrange the operation buttons and action signal lights of the machine-side operation box equipment in each area, and connect the signals of these operation buttons and action signal lights to the input and output boards of the control PLC in the electrical room through construction wiring On, and then by the PLC control program to control the action of each device. [0003] With the continuous improvement of ...

AI Technical Summary

Problems solved by technology

[0004] 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;

[0005] 2) There are many operation buttons and switches on the operation box, the amount of cables is relatively large, and the engineering volume of wiring is correspondingly high;

[0006] 3) There are many IO modules in the PLC, and the operation buttons of the close control operation box of the traditional operation line occupy about 1 / 3 of the IO points of the PLC;

[0007] 4) Pay attention to the weak status display of manual operation. If a more complete status display is required, an operation panel such as OP needs to be added, which will increase the cost and increase the volume of the operation box;

[0008] 5) It is almost impossible to expand the function. 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;

[0009] 6) When carrying out on-site self-reliance projects such as on-site equipment debugging and production preparation, the traditional on-site fixed close-control operation box has frequent listing and delisting during safe listing, which takes up a lot of time

[0010] Aiming at the above problems, we have been looking for the best solution, but due to the limitation of safety factors and the communication limitation of wired network, we cannot realize the breakthrough of eliminating the on-site fixed close-control operation box
