A portable intelligent synchronous proximity control device for hot rolling finishing line

Abstract

The invention discloses a portable intelligent synchronous near-control device for a hot-rolling finishing line, which establishes a communication connection with S7 PLC, including a plurality of industrial intelligent panel bases installed beside the machines in each process area of ​​the hot-rolling finishing line, and An industrial smart panel compatible with any industrial smart panel base; the industrial smart panel base includes a base body, and an NFC identification card, an emergency stop switch, and a key switch on the base body; the industrial smart panel has a touch screen and an NFC module , communication interface, the industrial intelligent panel is equipped with an operating system; the NFC identification card is compatible with the NFC module; the emergency stop switch and the key switch are connected to the S7 PLC through hard wiring. The invention overcomes the shortcomings of the existing fixed on-site close-in control operation box next to the machine of the hot-rolling finishing line, which has a large volume and blocks the line of sight, a large wiring project, high cost of input and output modules, and unchangeable operation interface.

Description

technical field [0001] The invention relates to a near-control operation device for a hot-rolling finishing line, and more particularly, to a portable intelligent synchronous near-control device for a hot-rolling finishing line. Background technique [0002] In domestic and foreign iron and steel enterprises, the traditional manual near-control operation adopts the on-site operation mode, such as: in the entry 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 these operation buttons and action signals and other signals to the input and output boards of the control PLC in the electrical room through construction wiring. Then, the action of each device is controlled by the control program of the PLC. [0003] With the continuous improvement of labo...

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
