Problems solved by technology

[0003] At present, the test scheme for the IMA system mainly adopts software simulation or simulation technology. After modeling the IMA system, it solves the problem of resource allocation in the software development stage through digital simulation. However, the existing simulation test environments are all oriented to IMA. The test environment of application software lacks fault management for IMA, especially for the three-layer fault management mechanism of IMA process level, partition level and module level. It lacks fault management modeling, use case generation, fault triggering and response collection. series of test methods

Embodiment

[0044] The error model attachment EMA is used to model the attributes of components, connection error time and error probability, and is used to describe the reliability information of the system model operation. Information about the error state. EMA defines multiple keywords for AADL to describe system faults, fault propagation, and related attributes. In order to further describe faults and propagation conditions and relationships, EMA also adds fault / error transformation and attribute fields to achieve specified state transitions A description of the condition.

[0045] The fault information of a single component can be included in the error model attachment EMA, including the fault state of the component, the path of the fault state transition and the random parameters of the fault. The reliability information about the fault influence relationship between components includes the input and output conditions of fault propagation and the fault state transition conditions o...

Abstract

The invention discloses an IMA system health monitoring and testing method based on AADL. Aiming at the health monitoring function in IMA fault management, corresponding test requirements are put forward, and AADL is used to model the fault management of the IMA system to provide faults for the IMA system test environment. Management information, by analyzing the IMA fault management test cases, by modifying the program code and configuration to achieve fault triggering, thereby verifying the health monitoring function.

Description

technical field [0001] The invention relates to the technical field of software testing, and more specifically relates to a testing method for health monitoring of an IMA system based on AADL. Background technique [0002] Fault Management (FM) is one of the important functions of the IMA system, which is mainly responsible for the detection, location, isolation and elimination of faults that occur during system operation. Health monitoring software is an important part of fault management. It is provided by the operating system and is responsible for monitoring errors and faults of hardware, operating system software, and application software in the system. The basic function of health monitoring software is to detect faults. In order to test the function of health monitoring software, it is necessary to stimulate faults. When faults occur, observe whether the health monitoring software detects faults, so as to achieve the purpose of testing. [0003] At present, the test ...
