Method for performing real-time communication between manufacturing execution system (MES) and process control system (PCS) and middleware

Abstract

The invention relates to data communication between application systems and particularly provides a method for performing real-time communication between a manufacturing execution system (MES) and a process control system (PCS). The MES and the PCS in a database structured query language (SQL) statement-based database communication mode and/or a transmission control protocol (TCP)/Internet protocol (IP)-based Socket communication mode communicate with each other. A receiving module of communication middleware receives information in a format agreed by a sending party from a communication module of a sending party system and encapsulates the information into information in an internal format for being written into a message queue; and a sending module of the communication middleware extracts the information, resolves the information according to the internal format, encapsulates resolved data into data in a format agreed with a receiving party and transmits encapsulated information to a communication module of a receiving party system. The communication middleware and the method for communicating by using the middleware provided by the invention transparently transmit real-time data between the MES and the PCS.

Description

technical field [0001] The invention relates to data communication between application systems, in particular to a method and middleware applied to real-time communication between a production execution system (MES) and a process control system (PCS). Background technique [0002] The MES system provides enterprises with an effective way of efficient and transparent management of the production process, and optimizes the management of the entire production process from the production order to the completion of the product through the transmission of information. [0003] However, in the process of data exchange between the MES system and the on-site PCS system, each application developer has its own communication system. Some developers with strong technical strength have their own perfect communication system and their own communication standards; most developers have not formed their own communication system, and the development process of communication modules is carried ...
