Abstract

The invention provides a multi-domain collaborative distribution type simulation system comprising a main control module, a data service module and a model interface module. The main control module is used for loading description documents of a preset model to obtain corresponding model information, setting clock fundamental frequency according to the model information, issuing the clock fundamental frequency and simulation control demands, arranging data transmission channels between the models in the data service module according to the model information, and defining data update periods of data channels. The data service module is used for establishing a data link which has an independent data transmission period, and providing the data channels for collaborative distribution type simulation data. The model interface module is used for establishing a connection relationship and schedule management of the main control module and a simulation sub-engine, and sending the clock fundamental frequency and the simulation control demands to the simulation sub-engine to complete calculation of the corresponding models. The multi-domain collaborative distribution type simulation system supports derivation of all simulation soft wares, and has the advantages of being high in calculation precision of collaborative simulation and high in calculation efficiency, and collaborative simulation is not prone to be caused.

Description

technical field [0001] The invention relates to a multi-field collaborative distributed simulation system, which belongs to the technical field of digital distributed collaborative simulation of engineering systems. Background technique [0002] Engineering systems (including aircraft, missiles, satellites, automobiles, etc.) are usually composed of subsystems in different fields such as mechanical, electrical, hydraulic, fuel, environmental control, etc., so modeling and simulation software in various fields (such as Matlab / Simulink, ADAMS, Simplorer, Flowmaster, AMESim, etc.) for system analysis. Subsystems in different fields influence each other, so simulation software in different fields is needed for co-simulation analysis to complete the function of large system analysis. [0003] The simulation software in different fields has different modeling mechanisms and calculation methods, the calculation step size is usually not controlled externally, and the software clock...
