The Starting System Automatic Test Platform Based On Virtual Instrument Technology Aircraft Design And Realization

The subject of the automation testing platform for the aircraft trigger system comes from China Aviation Experiment Academe. This testing system is designed for the aircraft trigger system QDX-11, QDX-13, and QDX-14, which detects the various performances. The purpose is to test new production of the aircraft trigger system whether the performance parameters have a good characters and regulating requirements. The current testing system has been developed and put into working.This paper introduces the design and implementation of automatic testing platform for an aircraft trigger system. Focusing on this theme, the article analyzes the platform for testing theory and methods to design programs system is hardware design and software programming optimization analysis of key issues. The purpose of a thesis is to study the wisdom of aircraft components offline simulation test technology maintenance and inspection to investigate the new method of the intelligence components.First, the automation testing platform for the aircraft trigger system is based on the technology of the virtual instrument. Duing this paper, the status and development of the virtual instruments is discussed briefly and its composition and structure of the virtual machines is analysised. Moreover, the virtual instrument overview of the typical technology development is introduced.Second, the article discusses three types of aircraft trigger system which are tested briefly on the principle of the aircraft trigger system; On the basis of the testing system designation, trigger system to test theories of aircraft designation and data processing method are described.Since then, the paper describes in detail the software and hardware design with the platform for automatic testing aircraft trigger system. In hardware design, the main parts of the testing system consists of PIO-821PGL multifunction data acquisition cards based on the PCI expansion card, and the use of Signal conditioning module design. It is focused on computer hardware testing system and the interface between the various definitions. The software exploiture platform uses Lab/windows, which is the object-oriented software and rapid application designation for...
