Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only specific embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] When the installed equipment or external subsystems are connected to the hardware-in-the-loop simulation system, heterogeneity is the root of the access, and the existence of heterogeneous components in the system may cause the subsystems in the system to fail to achieve effective interaction. Therefore, if figure 1 As shown, based on the semi-physical interface provided by the simulation verification platform, the present invention regulates the communication...

Abstract

The invention discloses a semi-physical simulation verification method and a semi-physical simulation verification system. The semi-physical simulation verification method comprises the following steps: establishing a mirror image virtual node and a spatial information network of real equipment in a simulation network; based on a semi-physical interface of the simulation network, mapping the real equipment to the mirror image virtual node; establishing a protocol stack of the mirror image virtual node in an application layer of a kernel protocol stack of an operating system; and when the simulation network mirror image virtual node receives system frames of other nodes, Ethernet frame packaging is carried out, and data interaction with real equipment is carried out through an adapter Ethernet port. According to the invention, whether the packet interaction response format realized by the protocol is consistent with the standard interface definition can be verified, and the interface intercommunication and protocol signaling interaction capability between different protocol realization software can be tested; according to the method, the fault identification and response time, the service rerouting recovery time and the error or interference information identification and response capability of a protocol can be evaluated, and the robustness test of protocol software can be carried out.

Description

technical field [0001] The invention belongs to the field of simulation, and in particular relates to a semi-physical simulation verification method and system. Background technique [0002] Simulation verification technology can effectively overcome the limitations of physical tests, significantly shorten the development cycle, reduce technical and project risks and development costs, and has become a new form of testing that is paralleled with physical testing. Simulation verification and physical test can complement each other and complement each other. Simulation verification can make up for the insufficiency of physical test, and support test and evaluation work to improve safety, efficiency and effectiveness. [0003] Although digital simulation has the ability of large-scale simulation, because each object in the digital simulation is based on a physical scenario, the reliability is poor. Therefore, how to enhance the credibility of the simulation has become an urge...
