The invention provides a multi-level multi-granularity cross-domain joint simulation event scheduling method and system, and the method comprises the steps: carrying out the unified management and control of simulation resources of a digital simulation system, a semi-physical simulation system, a real device and a real device simulator which are different in level, granularity and cross-domain distribution through a hierarchical modular joint simulation engine structure; proposing a frame-based real-time discrete event synchronization algorithm, and adding a real-time event scheduling servicemodule on the basis of a discrete event simulation engine, so the simulation engine can operate in two modes of logic time or real time, unified scheduling management of different types of simulationengines is supported, and the problem of simulation propulsion of different simulation systems is solved.

Description

technical field [0001] The present invention relates to the field of simulation technology, in particular to a multi-level and multi-granularity cross-domain joint simulation event scheduling method and system. Background technique [0002] Advanced distributed simulation technology is the main support means of joint combat simulation of weapons and equipment. With the acceleration of the construction of a modern combat system, the scale of the combat system is getting larger and larger, and the elements involved in the joint simulation are becoming more and more complex. Carrying out multi-weapon system joint combat simulation tests needs to cross multiple simulation levels such as weapon equipment system level, weapon system level, and weapon system sub-system level, and integrate digital simulation systems, semi-physical simulation systems, actual installations, and actual installation simulators at different granularities. , heterogeneous and cross-domain distributed te...

Problems solved by technology

However, most of the transformation strategies for real-time performance of RTI are at the software level. Although the real-time performance of RTI can be extended within a certain range to meet the real-time constraints of some specific systems, the underlying communication cannot be predicted. In fact, the management service does not really achieve real-time clock synchronization, so the above strategy still cannot be applied to distributed real-time systems with strong real-time constraints in hardware-in-the-loop simulation systems
