The Design and Implementation of Testability Verification Platform for Airborne Electronic Equipment
In view of the difficulties in fault detection and isolation and the difficulties in maintenance and guarantee of mordern airborne electronic equipment in the course of mission execution,a testability validation platform for airborne electronic equipment is designed by utilizing the method of fault injection.Firstly,the overall architecture,cross-link-ing relationship and working principle of the verification platform are elaborated.Then,based on PXI technology,the automatic test subsystem and fault injection subsystem of the testability verification platform are designed,and the adaptive interface module is also taken into account.Meanwhile,the verification platform integrates VITE software as the platform's fault injection software development environment.Finally,the test signals and fault modes of an airborne power distribution system are analyzed,and the fault injection control program is developed,which provides a techni-cal reference for improving the testablility level of airborne equipment.
