Distributed drive middleware based on remote procedure call protocol

Abstract

The invention discloses a distributed drive middleware based on a remote procedure call protocol. A software architecture of a client and an IVI drive server is adopted, wherein the IVI drive server runs on a node computer with test resources; a test script is sent to the IVI drive server on the client through the remote procedure call protocol; and an IVI drive program on the IVI drive server drives a tested product according to the test script, and returns a result to the client through the remote procedure call protocol. According to the invention, the coupling relationship between test software and hardware resource drive is greatly reduced, the test resource drive is used as a universal service to be provided for the test software, so that a test developer only needs to care about thefunction logic and the verification process and does not need to care about the resource supply when developing the test software (simulation, use cases and the like), and the avionics test verification efficiency and the test software flexibility are improved.

Description

technical field [0001] The invention relates to the technical field of avionics system testing and simulation, in particular to a distributed drive middleware based on a remote procedure call protocol. Background technique [0002] The modern avionics system is a highly integrated and modular complex system. In order to realize the information interaction inside and outside the system, a variety of high-standard network, bus, and point-to-point communication technologies are often used. In view of this, when testing avionics systems, more and more types of simulation resources are required. In fact, testing a single type of T2-level avionics system requires the use of nearly 10 different types of communication simulation resource boards. When developing traditional test equipment, the test software is generally used to directly call the API driver function provided by the manufacturer, but this has two major drawbacks: on the one hand, test software developers need to spend...

Problems solved by technology

[0003] Aiming at the problems of tight coupling between traditional test system hardware drivers and simulation test software, inability to reuse, and high maintenance costs, the purpose of the present invention is to provide a distributed driver middleware based on the remote procedure call protocol, using interchangeable virtual instrument (IVI) normative thinking, using the remote procedure call protocol (PRC) and distributed structure, designed the distributed driver middleware of test resources, greatly reducing the coupling relationship between test software and hardware resource drivers, and using test resource drivers as a general Services are provided to test software, so that test developers only need to care about functional logic and verification process when developing test software (simulation, use cases, etc.), and do not need to care about resource provision, which improves the efficiency of avionics test verification and the flexibility of test software
