Fault injection method and system

Abstract

The invention discloses fault injection method and system and belongs to the field of fault injection. The system comprises an action enumeration module, a device search module, an action creating module and an execution control module. The action enumeration module stores and displays preliminarily set action items used for fault injection and transmits user-selected action items and action types thereof to the action creating module. The device search module searches all devices currently connected to the system. The action creating module provides users with parameter setting according to the action types of the action items transmitted by the action enumeration module, creates action items according to parameters of the action items set by the user, selects a list of devices suitable for the action items from the devices searched from the device search module, and determines the devices related to the action items from the list of devices according to user commands. The parameters of the action items include executive modes. The execution control module executes the action items on the devices related to the action items according to the executive modes of the created action items. The fault injection method and system allow for various types of automatic fault injection.

Description

technical field [0001] The invention belongs to the field of fault injection, in particular to a fault injection method and system. Background technique [0002] At present, the reasons for the failure of aviation equipment during normal operation are often unpredictable, so the need to artificially inject various faults in the normal environment to detect the reliability and correctness of the equipment has been raised. Among them, for the fault of the physical layer, the fault of open circuit or short circuit can be realized manually by disconnecting or short-circuiting the communication bus, but there is no solution for the protocol layer. And in practical applications, the cause of equipment failure may not be single. Generally, an aviation product involves multiple communication buses, so a general multi-bus fault injection comprehensive platform is strongly needed. In the current international market, there is no comprehensive fault injection system, only some compan...
