Co-simulation method and device based on heterogeneous system

Abstract

The invention proposes a heterogeneous system-based co-simulation method and device. The methods include: establishing a communication connection between the combat simulation system and the radar screen simulator; the simulation engine determines the hosted radar from the co-simulated combat plan, and sends the radar parameters of the hosted radar and the platform parameters of the combat plan to the radar screen simulation The radar screen simulator executes the initialization of the joint simulation based on the received radar parameters of the managed radar and the platform parameters of the combat plan; starts the joint simulation, including: the simulation engine performs the first simulation processing, and the first simulation processing simulates the operational range The working state of each entity equipment and the maneuvering state of the combat target except the managed radar; the radar screen simulator executes the second simulation process based on the simulation result of the first simulation process and the single-step step size, and the second simulation process simulates the operation state of the managed radar Working state: integrating the processing results of the first simulation processing and the second simulation processing.

Description

technical field [0001] The invention belongs to the field of co-simulation, in particular to a co-simulation method and device based on heterogeneous systems. Background technique [0002] Model resolution refers to the level of detail in which the model describes the objective world, also known as granularity. In the field of military simulation, the simulation model is usually divided into five levels of resolution: strategic level, campaign level, tactical level, equipment level, and engineering level, and the level of detail increases in turn. Heterogeneous systems have different resolutions, and multi-resolution model co-simulation integrates models of different resolutions into the same model system to simulate the objective world. [0003] At present, the multi-resolution co-simulation technical solution mainly includes (1) synchronous operation of multi-resolution models, that is, the output results of the corresponding resolution models are selected according to us...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that for different resolution models of the same entity, due to the different input and output data protocols, it is difficult for the high resolution model to provide a reference for the parameter determination of the low resolution model; at the same time, it is difficult to directly integrate the high resolution model into the heterogeneous system (lower model resolution) model system, so when carrying out co-simulation, business code needs to be rewritten / added, which increases enterprise costs, reduces development efficiency, and increases the risk of system stability
