Embodiment Construction

[0036] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0037] 1. The whole process control system adopts VB6.0 version programming. The process control computer server and client are respectively Chinese Windows2000Server and Windows2000professional operating systems, with an open programming environment. The database of the process control system is Oracle9i and is installed on the process control computer server together with the process control system. The server and client adopt C / S structure. The server is placed in the main power room of the unit, and the client is placed in the field operation console The communication between them is connected by two switches, and the two switches are connected by multi-mode optical fiber. The communication between the process control system and the basic automation PLC utilizes industrial Ethernet and uses TCP / IP protocol for communication. The entire syste...

Abstract

The invention provides a cold strip steel leveling unit process control method. The method comprises the steps that the VB6.0 version programme is adopted, and a server and a client side are of a C / S structure; the communication method of a process control system and a basic automation PLC, a message processing method, a message structure and message content are established, the functions and the solution of functional modules of the process control system and the function achieving technical condition of the process control system are established, and therefore an operator can conveniently manage a steel coil plan, set values, technological parameters, finished product data, downtime and a team and group through a customized HMI; various accurate data are provided for an ERP system. The whole process control system is clear in functional partitioning, capable of being transplanted and popularized conveniently and suitable for the process control of a cold rolled leveling unit.

Description

technical field [0001] The invention belongs to the field of automatic control of steel rolling, and in particular relates to a control method for production process data of a cold rolling skin leveling unit. Background technique [0002] In order to obtain ideal product quality in the production of cold-rolled strip skinning unit, the process control system must be fast, reliable and accurate to realize the production plan management of cold-rolled strip steel skinning unit, steel coil tracking control, and rolling set value calculation. development, rolling strategy optimization, finished product data management, shift and downtime management. The process control system is a computer system used to manage production process data in the automatic control system of the production line. At present, the control method of the strip skinning unit introduced in China generally does not have the process control computer program to complete the calculation of the set value of each...
