Abstract

The present invention discloses a real-time data communication system applied between a process monitoring control system and an emulation support system. The real-time data communication system comprises an OPC (OLE for Process Control) communication module in communication with the process monitoring control system, a DDE ((Dynamic Data Exchange) communication module in communication with the emulation support system, and a data conversion module used for performing mutual conversion on data in the OPC communication module and the DDE communication module. The present invention further discloses a real-time data communication method applied between the process monitoring control system and the emulation support system. The method comprises the steps of communication data reception, data conversion, communication data transmission and the like. The real-time data communication system and method has beneficial effects of implementing fusion of two different data exchange mechanisms of OPC and DDE and implementing real-time communication of large data volume.

Description

technical field [0001] The invention relates to the field of data conversion communication, in particular to a real-time data communication system and method applied between a process monitoring control system and a simulation support system. Background technique [0002] ABB Freelance 2000 (process monitoring and control system) is a comprehensive open control system produced by ABB, which integrates the functions of the distributed control system (DCS) and the programmable control system (PLC), and has DCS The adjustment ability of complex analog loops and the friendly and rich human-machine interface are widely used in the monitoring and control of industrial production equipment and power plants, and have good compatibility and expansion capabilities. [0003] The simulation support system simulates the actual operation process of the device by modeling and simulating the industrial production equipment or power plant, and organically combines modeling, model debugging a...
