Embodiment 2

[0113] Considering that in the actual hardware-in-the-loop simulation process, in addition to the simulation model based on the mathematical modeling tool for the simulation object's functional algorithm, it is also necessary to simulate the communication format and flow of the physical interface of the simulation object. The communication format and process simulation model of the physical interface is called the process model. During the simulation process of the process model, it is necessary to connect physical objects or physical effect devices, and the physical objects or physical effect devices cooperate to complete the simulation task. Therefore, in order to adapt to the simulation of this type of process model and enhance the adaptability of the distributed real-time simulation platform, Embodiment 2 of the present invention has been improved on the basis of the scheme of Embodiment 1 to form a simulation model that can simultaneously satisfy the requirements of the si...

Abstract

The invention discloses a distributed real-time simulation method, belongs to the technical field of simulation, and is used for solving the problems of unreasonable simulation task distribution and the like in the existing simulation process. The method comprises the following steps: a simulation master control system generates a simulation task list according to simulation tasks and a calculation node list and sends the simulation task list to a simulation management bus; the simulation task list comprises simulation sub-tasks and computing nodes for deploying the simulation sub-tasks; based on the received simulation task list, the simulation management bus sends the simulation sub-task to a computing node for deploying the simulation sub-task; the simulation master control system sends the simulation control instruction to the computing node for deploying the simulation sub-task through the real-time simulation bus so as to control the progress of executing the simulation processing process by the computing node; and the computing node executes a simulation processing process based on the received simulation sub-task and the simulation control instruction, and interacts data generated in the simulation processing process with the simulation master control system and other computing nodes through the real-time simulation bus.

Description

technical field [0001] The invention relates to the technical field of simulation, in particular to a distributed real-time simulation method. Background technique [0002] In the process of using the simulation platform to simulate the simulation objects, there are many interactive objects involved, various interactive data, and complex interactive processes; at the same time, different simulation tasks require different computing resources. If there are too many computing resources, it is easy to cause waste of resources. If the preset computing resources are too few, it cannot meet the simulation requirements of the simulation task with a large amount of calculation. [0003] To sum up, how to optimize the simulation process based on the above-mentioned problems existing in the existing simulation process, realize the reasonable allocation of simulation tasks, optimize the simulation configuration and the data interaction process during simulation, is an urgent problem to...
