Airborne Panel Series Circuit Module Test System Software Design

Shi, Guo-Qing / Zhang, Jian-Dong

Airborne panel series circuit modules are used to process and transform the information between the aircraft cockpit control panels and the avionics system. A kind of test system software design for the airborne panel series circuit modules using the PXI host system as the testing platform is introduced in this paper. The test system architecture, software design idea and realization method are also discussed. In order to test the airborne panel series circuit modules, whose all kinds of interface signals are needed to provide according to the circuit modules’ test requirements. The most important function of test system is to provide excitation signals to the tested object, while the response signals of the tested object is collected, so the test results can be formed by the test criterion. In the software design, the different test processes are used for the different test objects. The test work can be completed according to the test process, the test data and test results formed in the test can be saved to the database. In the test process, the connection between the test program and database is established. All test data and results are managed by the private database management system. The entire test system uses the top-down design methodology, and host computer adopts PXI system to control the tested modules. The test system has been well applied in project, and its stability and excellent performance have been proved in experimental work.
