System and method for controlling production process of petrochemical enterprise on basis of manufacturing execution system (MES) workflow

Abstract

The invention discloses a system for controlling the production process of a petrochemical enterprise on the basis of manufacturing execution system (MES) workflow. The system comprises an MES production flow model base, an MES production flow information database, a workflow server, a production control terminal workstation and a data interaction interface, wherein the MES production flow model base is used for storing MES production flow link models and an MES whole production flow model for describing topological structures among the MES production flow link models; the MES production flow information database is used for storing production execution data in each link of the MES production flow; and the workflow server is used for invoking the MES production flow model base and the MES production flow information database to execute an MES workflow task. The invention also discloses a control method of the system for controlling the production process of the petrochemical enterprise on the basis of MES workflow. The system and the method provide activity execution information of panoramic production links for operators in a graphical mode so as to control the progress of the production flow in real time and improve the production efficiency.

Description

technical field [0001] The invention relates to the field of process industry production process control, in particular to a petrochemical enterprise production process control system and method based on MES workflow. Background technique [0002] The production process workflow technology of the process enterprise needs to solve the production coordination problem of multiple links in the complex process production process. MES (manufacturing execution system, manufacturing execution system) is an information execution system oriented to the workshop level between the upper planning management system of the production enterprise and the industrial control system at the field level. It controls the entire production process from the production order to the product completion Carry out production information management and data processing, including order data release, production instruction data release, production process execution monitoring, on-site production data collec...

AI Technical Summary

Problems solved by technology

[0003] Although the introduction of the MES system in petrochemical companies can improve production efficiency, petrochemical companies have the characteristics of long business processes, clear logical relationships before and after each business link, and relatively fixed business executors. The current MSE system is basically based on functional modules. Therefore, each business process link of MES will be isolated to a certain extent, and the logical relationship between each business link is not clear, which hinders the further promotion and application of MES system in petrochemical enterprises.
