Universal virtual experiment real object equipment access system

Abstract

A universal virtual experiment real object equipment access system comprises a hardware interface protocol converter, a virtual experiment proxy node and a configurable automatic real object equipment access gateway generator. The hardware interface protocol converter comprises a protocol conversion unit and a bus interface. The universal virtual experiment real object equipment access system has the advantages that on the basis of user software interface configuration, a virtual experiment access gateway matched with a real object equipment transmission protocol is automatically generated, the heterogeneity problem of the transmission protocols and the transmission interface is solved, and rapid and seamless linkage of real object equipment and virtual equipment middleware is achieved. According to the universal virtual experiment real object equipment access system, on the basis of flexible protocol configuration, rapid and seamless integration of a real object virtual experiment verification platform is achieved, the heterogeneity problem of the various transmission protocols is solved, user zero-code compiling is achieved, and the development period of the virtual experiment verification application is shortened.

Description

technical field [0001] The invention belongs to the technical field of virtual experiments, and relates to a general virtual experiment physical equipment access system. Background technique [0002] With the sharp increase in the sophistication and complexity of military products, virtual testing, as a low-cost, high-efficiency, and short-period test verification method, has become an effective method for auxiliary model system-level testing, and has been widely studied in the military industry at home and abroad. and apply. ' [0003] At present, virtual test verification is developing in the direction of "integration of virtual and real", which is to organically unify the support of virtual test and the verification of physical test, and evaluate whether the overall function and performance of complex products meet the design requirements in a virtual and real test environment. It is required, on this basis, to verify the coordination and matching of interoperability am...

Problems solved by technology

How to connect the physical test equipment to the supporting environment of the virtual test for unified testing has become a key technology of "virtual-real fusion". There are two main difficulties: first, the bus interfaces of the physical equipment in the virtual test verification system are diverse, Commonly used bus interfaces include 1553B, UART (RS232 / 485 / 422), CAN and other types, which are different from the virtual test support platform mainly based on Ethernet, and different physical test equipment have different transmission protocols, which are different from virtual test verification The system is incompatible and belongs to a heterogeneous system; secondly, the physical test equipment has high requirements for real-time performance. If the real-time performance cannot meet the requirements, the test data obtained by the virtual system will not reflect the real performance of the test equipment.
