A general virtual test physical equipment access system

Abstract

A general virtual test physical device access system, including a hardware interface protocol converter, a virtual test proxy node and a configurable real device access gateway automatic generator; the hardware interface protocol converter includes a protocol conversion unit and a bus interface; the system advantage Through the configuration of the user software interface, a virtual test access gateway that matches the transmission protocol of the physical equipment is automatically generated, which solves the heterogeneity problem of the transmission protocol and the transmission interface, and realizes the fast and seamless connection between the physical equipment and the virtual test middleware; Through the flexible configuration of the protocol, the present invention realizes the fast and seamless integration of the virtual test verification platform of physical equipment, and at the same time solves the heterogeneity problem of various transmission protocols, realizes the user's "zero code" writing, and shortens the development of the virtual test verification application cycle.

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.
