Embodiment 1

[0034] Embodiment 1: as Figure 6 As shown, the electromechanical system real-time simulation platform adopts a distributed parallel co-simulation architecture. The upper part is the design and analysis environment, including 1 simulation design operation management computer and 9 virtual test computers; the lower part is the simulation computing environment, which is composed of 12 simulation computers. Users can design simulation tasks in the design analysis environment, and deploy the simulation tasks to the next simulation computing environment for simulation calculation. Simulation tasks are usually composed of simulation models built by simulation software (AMESim, Simulink, and C / C++), and involve multi-domain multi-software co-simulation issues.

Embodiment 2

[0035] Embodiment 2: as Figure 7 As shown, the underlying operating platform adopts a distributed parallel co-simulation architecture. The upper office is a multi-user design and development environment, and the lower simulation computing laboratory is a simulation computing environment. Each user in the office can simultaneously design, deploy, manage and monitor simulation tasks, and can use all the simulation computers in the simulation computing laboratory. The simulation computer in the simulation computing laboratory runs the Matlab M file simulation model and the C language simulation model. The clock synchronization of all simulation models is completed by running the simulation engine on a simulation computer in the simulation computing laboratory, and the data interaction of the simulation models is completed by calling the soft bus API function through the co-simulation interface.

Abstract

The invention discloses a distributed parallel co-simulation architecture. According to the architecture, a simulation soft bus is defined, simulation software is interconnected with the simulation soft bus, and data cooperative interaction between the simulation software is completed through the simulation soft bus. According to the architecture, co-simulation tasks are decomposed from two dimensions of space and time, so that the simulation efficiency is improved, and multiple simulation tasks are supported to be executed concurrently at the same time through the partitioning technology of the simulation soft bus. According to the architecture, concurrent execution of multiple simulation tasks established by multiple users is carried out through a design environment; distributed computing and multi-node interconnection is achieved through the established simulation soft bus. Data interaction with the simulation soft bus is performed through an independent model interface relative tothe simulation software so as to complete collaborative calculation of the simulation software; and parallel synchronous resolving is completed through a simulation scheduling engine.
