Online rolling plan dynamic pre-analysis and self-adjustment system and method

Abstract

The invention relates to CIM (Computer Integrated Manufacturing) applicable for overall factory control and discloses an online rolling plan dynamic pre-analysis and self-adjustment system and method having quality information feedback. The online rolling plan dynamic pre-analysis and self-adjustment system comprises a rolling plan analysis module, a plan review condition generation module and a plan-regulation parameter evaluation module, wherein a rolling regulation management module and the rolling plan analysis module are connected to the plan-regulation parameter evaluation module through the plan review condition generation module; and the e plan-regulation parameter evaluation module is connected to a rolling technical parameter setting and calculating module through a technology and model parameter adjustment module. The method comprises the steps of: analyzing the rolling plan; comparing the rolling plan with the rolling regulation; screening regulation items; generating a plan review condition table and setting a rule-breaking and limit-exceeding mark; and displaying limit specification of the technology and prompting and automatically adjusting technological parameters. According to the online rolling plan dynamic pre-analysis and self-adjustment system and method, disclosed by the invention, automatic plan review is realized, plan reviewing efficiency is improved and the problem that plan defects cannot be discovered in time and exactly due to missed detection and misjudgment of artificial review can be avoided.

Description

technical field [0001] The invention relates to a computer integrated manufacturing (CIM) suitable for overall factory control, especially suitable for the planning, quality and rolling process control of hot rolling production in metallurgical enterprises. Background technique [0002] The hot rolling mills of modern metallurgical enterprises usually adopt a four-level computer control system (L4~L1). The main functions of the control systems at all levels are as follows: [0003] Production management level L4, mainly completes contract management, financial management, production plan preparation, mutual coordination of each production line, application materials according to the contract, sends production plan to L3 level, collects production performance of L3 level, tracks production status and quality status, Organize tasks such as delivery of finished products. [0004] The production control level L3 mainly completes the execution control of the production plan, inc...
