Embodiment

[0074] Taking the conversion of the satellite simulation model as an example, the model simulates the satellite orbit and on-board sensor functions. In addition to its own kinematics model, it needs the relevant parameters of the ground target model, and it can be carried out in the simulation 3D visualization tool provided by the platform. performance needs.

[0075] First, according to the established time management mechanism, the internal functions of the satellite simulation model are divided into two parts: one part describes the state transition function of satellite orbit state variables such as position, attitude, and velocity over time; the other part describes the satellite simulation model for such as The processing function for receiving special events such as on-board sensor opening and closing, and the processing function for issuing special events such as detecting a specified target after obtaining the simulation results. Since the satellite simulation model n...

Abstract

A simulation model conversion method based on a distributed interactive simulation platform, includes the steps: (1)determining the time management mechanism used in the simulation model conversion process to make the federal member of the simulation model unitedly order the insulated clock of the distributed interactive simulation platform, executing the simulation step length propulsion of the simulation model according to the simulation clock of the distributed interactive simulation platform; (2)dividing the intrinsic function of the simulation model to be converted into two parts: one part being a state transition function, the other part being an event handling function; (3) according to the state transition function and the event handling function, determining the model state parameters of the simulation model to be converted ordered and issued for the distributed interactive simulation platform and the special event ordered and issued for the distributed interactive simulation platform, forming the interface describing file; (4) according to the interface describing file, generating the object class library and the interactive class library for the conversion of the model to be converted; (5) according to the generated object class library and interactive class library, reforming the model to be converted and completing the conversion of the simulation model.

Description

technical field [0001] The invention relates to a simulation model conversion method based on a distributed interactive simulation platform, belonging to the technical field of computer simulation. Background technique [0002] The High Level Architecture (HLA) standard proposed by the United States for distributed interactive simulation has been accepted as an international simulation standard. HLA provides a general framework for constructing and describing distributed simulation, and solves the problem of interoperability and reuse in simulation systems. Two key issues of gender. The system realized based on the HLA standard is flexible and open, which makes the large-scale simulation application system possible. There are many researches on the distributed interactive simulation platform based on the HLA standard at home and abroad. The patent (200510123864.3) provides an integrated distributed interactive simulation platform implementation method. This method combines ...
