WEB-based aluminum cold-rolling mill shape control man-machine interface operation method

Abstract

The invention provides a WEB-based aluminum cold-rolling mill shape control man-machine interface operation method; the man-machine workstation adopts a PC installed with IE browser to replace a touch screen or an integral workstation, a man-machine interface workstation is connected with an OPC XML-DA server through Internet, the OPCXML-DA server used as an OPC server is connected with a shape control system and a field intelligent instrument; meanwhile, the OPCXML-DA is used as a WEB server to upload the bottom data to the network; so the remote monitoring is realized through any PC connected with the network. The man-machine interface workstation exchanges data with the shape control system through the Ethernet and the OPCXML-DA server so that the hardware investment and maintenance cost are reduced, and the remote monitoring and fault diagnosis level of the system are also improved.

Description

technical field [0001] The invention relates to a WEB-based man-machine interface operation method for aluminum cold rolling mill plate shape control, belonging to the technical field of aluminum cold rolling mill control. Background technique [0002] In the non-ferrous metal processing industry, the computer control level of the aluminum cold rolling mill production line is relatively high, and the automatic control system plays an important role in it. The automation control system is divided into the basic automation system and the process automation system. For the basic automation system, the shape control system is a key component and a key means to ensure the export quality of rolled strips. The man-machine interface workstation of the cold rolling mill adopts a touch screen or an integrated workstation. The man-machine interface generally adopts C++ high-level language or configuration language programming, and generally adopts MPI, MODBUS, PROFIBUS, CAN bus, etc. t...

AI Technical Summary

Problems solved by technology

Most of the enterprise's secondary and tertiary systems are connected by Ethernet, and it is difficult to share data with the primary control system

[0003] The block diagram of a typical flatness control system of aluminum cold rolling mill is as follows: figure 1 As shown, the system configuration and network connection method have the following limitations: ①The configuration cost is high, the human-machine interface workstation basically adopts a touch screen or an integrated workstation, and configuration software needs to be purchased and installed; ②The equipment maintenance cycle is long, if Human-machine interface failure, maintenance and system and configuration software installation cycle is long; ③ enterprise information system integration is difficult, the communication interface of each equipment control terminal is not unified, and the operating system is not unified, it is difficult to realize data sharing with ERP to improve the enterprise Degree of informatization; ④Difficult remote monitoring, enterprise managers and technicians cannot keep abreast of equipment operation and personnel operation; ⑤Difficult remote fault diagnosis, unable to provide data for remote fault diagnosis users, difficult to achieve remote fault diagnosis
