Research of Real-Time Data OPC Asynchronous Communication in Incentive-Type Simulator

Abstract

This paper describes the working principle of OPC technology, combined with incentive-type simulator working mechanism, and given the development method of OPC asynchronous communication and the concrete realization using Visual C + +6.0. Using memory-mapped file to set up real-time database for system running, through memory-mapped file to open shared memory area and to operate its data. This method can realize the sharing of process data, and ensures the real-time responsiveness to Ovation DCS server database to read and write data. With faster data transfer rates, security and high reliability in the thermal power plant automation has a strong versatility and practicality.
