Design And Implementation Of Test Of The Avionic System

In recent years, with Chinese integrated modular avionics system (IMA)development and guarantee of the importance of quality of this syste m, the research onIMA test method become the focus of attention of the scientific and technical personnel.Due to the high complexity of IMA, the characteristics of high integrated posed achallenge to test. In order to test for the demand response to the IMA complex, moreand more research team practice unceasingly, looking for ways to solve the problemsexisting in IMA test.According to the test requirements of IMA complex, studies the test method ofintegrated modular avionics based on LDRA Testbed. In this paper, based on the basicmethod of related concepts of system architecture of avionics model and the IMA test, itintroduces the related technology of IMA test. In this paper, through the detailed needsanalysis, analysis of the IMA simulation and testing environment, it presents thedistributed IMA software testing platform. Through the LDRA Testbed test tooldesigning the test cases of each module in IMA system, the IMA test run.The test results show that, the test scheme in this paper not only meet the IMAcomplex test requirements, but also to the IMA test solutions and we were givencomprehensive and effective set of function coverage.
