Abstract:

Live-virtual-construction (LVC) simulation provides effective technical means for equipment system test. In order to solve the problem that the interaction between a large number of heterogeneous simulation resource objects in the test could not meet the real-time demand of the test task, the real-time scheduling model of simulation resources is researched. The functional components of the model are analyzed, and the scheduling model is divided into three sub-models: remote method communication implementation, remote method cloud service, and optimized scheduling strategy. The functions of each sub-model and their relationships are analyzed, the operation steps and implementation principles of the model are given. A standard experimental environment is constructed to verify the model algorithm. The experiment shows that under the standard test environment where the delay requirement of the model is less than 1 ms, the cloud service environment can bear the subscription requirement of about 30 nodes at most at the same time, and the scheduling success rate is all more than 98.5% and the packet loss rate is 0, which meets the performance requirements of the model.

Key words: simulation as a service (SAAS), live-virtual-constructive (LVC), equipment test resource, real-time scheduling model
