Problems solved by technology

[0004] 2) Failure to apply effective software incentives in the hardware reliability test: At present, in the field test flight and actual use of the aircraft, some of the faults are caused by hardware, and some are caused by software
In the previous reliability tests, the hardware was mainly assessed, but for the software, only one scene and one incentive condition were repeatedly used in the reliability test, which could not truly simulate the use status of the software, and did not effectively test the software. assessment, and cannot simulate the real use scenarios of the system, which affects the authenticity of the reliability test results

Embodiment

[0056] The display control software and hardware system in this embodiment mainly completes functions such as comprehensive display of system information, monitoring of system health status, control of system working status and working mode, task management, real-time data recording, human-computer interaction and centralized power-on. The tasks of the display and control software and hardware system include:

[0057] a) Pre-flight preparations: including power-on self-check and mission loading.

[0058] b) Climb: After the aircraft takes off, power on the system centrally, enter the operation interface to check the system status and navigation information.

[0059] c) Cruise: perform mission-related operations through the control interface.

[0060] d) Return flight: data unloading, system shutdown.

[0061] The software functions of the display control software and hardware system include: centralized power-on control, comprehensive display of system information, system he...

Abstract

The invention relates to a display control software and hardware system reliability test stimulation method based on section mapping. The method comprises the steps that firstly, a software reliability test section and a comprehensive environment stress section are determined; then, the software reliability test section and the comprehensive environment stress section are combined through section mapping to form a software and hardware reliability comprehensive test section, and test stimulation is generated through the comprehensive test section. The test stimulation generated through the comprehensive test section truly reflects the correlation between software running and external environment condition changes, test risks and resource waste caused when a software reliability test and a hardware reliability test are separately conducted are avoided, the product reliability can be verified through a single test while the test cost is reduced, and the test embodiment shows the feasibility, reasonability and effectiveness of the method.

Description

technical field [0001] The invention relates to a method for stimulating the reliability test of a display and control software and hardware system based on profile mapping, and belongs to the technical field of control. Background technique [0002] There are many problems in the implementation process of existing software and hardware system reliability test stimulus generation methods, mainly including the following aspects: [0003] 1) Product hardware reliability test and software test are carried out separately: the current domestic reliability test work on aviation airborne electronic products mainly includes two parts: the first part is to carry out reliability appraisal tests on hardware to verify the reliability of the hardware. Whether the reliability (MTBF) can meet the requirements; the second part is to carry out software testing on the software, and improve the reliability level of the software through software testing. At present, the hardware test and the s...
