The existing technologies are difficult to identify the airborne software faults and the corresponding causes, and thus cannot be applied in the development process of the airborne software, so the airborne software fault modeling and analysis technique based on the system architecture and operation diagram are proposed. Firstly,the airborne software fault identification approach based on the function failure analysis is proposed, which can be used to identify the airborne software faults caused by the interface data, time constraint and so on. And, the fault hierarchy modeling approach based on the static system architecture and the fault logic relationship modeling approach based on the dynamic operation diagram are constructed respectively, which can be used for constructing the software fault tree effectively. Then, the software fault reason analysis and safety requirement development strategy based on the software requirement and criteria is proposed. Finally, the engineering application of the airborne brake control software is conducted. The results show that the proposed airborne fault modeling and analysis technique is feasible, and consistent with the standard requirement, which is suitable for constructing the V& V loop of the airborne software fault analysis and validation. |
