Abstract

The invention provides an aircraft electromechanical system fault injection platform based on a LabView system. The aircraft electromechanical system fault injection platform comprises a system setting module, a network communication module, an interactive data processing module, a system fault injection module and a system state simulation module. Through pre-configuration (setting change process parameters such as a mean value, an extreme value and duration time of an interface signal) of an interface signal change process, a dynamic change process of a typical working state of an electromechanical system from a normal state to a fault is simulated, and a plurality of interface signal change processes are synchronized. Single or grouped control is carried out on changes of interface signals according to a specific fault mode, automatic fault injection of the aircraft electromechanical system is finally achieved, the method has the advantages of being easy and convenient to operate, visualized and the like, and the purpose of synchronous automatic fault injection can be achieved.

Description

technical field [0001] The application belongs to the technical field of aircraft fault simulation, and in particular relates to a fault injection platform of an aircraft electromechanical system based on a LabView system. Background technique [0002] Fault injection of common aircraft electromechanical systems often adopts methods such as artificial wire end disconnection and ground disconnection, so as to simulate airborne faults. However, this method has the risk of live operation and needs to destroy the wire connection relationship. In the case of a large number of faults, the workload is relatively large, the efficiency is low, and it is easy to make mistakes. [0003] Another kind of fault injection is realized by semi-physical simulation equipment. It is necessary to change the interface status from normal to fault one by one for the fault characteristic signals associated with the fault mode. The pre-configuration of the interface signal change process cannot be re...
