Co-simulation method for multiple semi-physical simulation systems

Abstract

The invention discloses a co-simulation method for multiple semi-physical simulation systems. The method comprises the following steps that: an intermediate interaction computer is added among multiple sets of semi-physical simulation systems; a plurality of reflective memory cards installed at the intermediate interaction computer and are connected with the multiple sets of semi-physical simulation systems respectively; and one of the multiple sets of semi-physical simulation systems is used as a main simulation system and other systems are used as slave simulation systems, the main simulation system generates a system timing clock, clock synchronization is carried out by interruption of the reflective memory cards and the intermediate interaction computer forwards a clock synchronizationsignal and simulation data, so that clock synchronization and data interaction of the multiple sets of semi-physical simulation systems are realized and the co-simulation of the multiple semi-physical simulation systems is completed. Therefore, a problem of interconnection and mutual communication under the circumstance of shortage of the reflective memory node resources of the multiple sets of semi-physical simulation systems is solved and thus cascade connection and co-simulation work of the multiple simulation systems are realized.

Description

technical field [0001] The invention relates to the field of simulation technology, in particular to a collaborative simulation method for a mostly physical simulation system. Background technique [0002] The hardware-in-the-loop simulation system is a system that simulates the target signal in the laboratory and analyzes and verifies the guidance and control system. The hardware-in-the-loop simulation system plays an indispensable role in reducing the research and development cost, shortening the development cycle and improving the development level. [0003] The hardware-in-the-loop simulation test system is mainly composed of an optical fiber network, a simulation computer, a turntable, and a target simulation system. Previous hardware-in-the-loop simulation systems mainly simulated a single tested product. As the multi-mode seeker-based weapon system enters the research and development stage and the multi-system cooperative combat mission is proposed, a single hardwar...
