Research on Integrated Testability Verification PlatformBased on Fault Identification

摘要:

针对目前测试性试验中缺乏有效的试验验证平台的现状, 创新性地提出了基于故障确认的一体化平台,具备装备功能性能测试、故障注入、测试性评估等功能。通过对测试性试验验证流程及步骤的论述,结合直接故障注入、等效故障注入、实际故障统计、测试性仿真分析等进行测试性综合评估,对一体化平台的硬件组成和软件框架进行了详细论述。最终将一体化平台应用于某型相控阵雷达的测试性评估试验,具有很强的工程推广价值。

Abstract:

At present, the useful platform for testability evaluation in testability verification is lacking. In order to solve the problem, the testability verification platform based on fault identification integrated with overall performance measurement, fault injection and testability verification is presented innovatively. By expatiating the flow and steps of testability evaluation and verification, the method of integrated evaluation is given by combining the directly fault injection, equivalent fault injection, and practical fault statistic with the analysis of testability simulation. The hardware architecture and software framework are detailed explained. The platform is used in the testability verification of some kind of active phased array radar, and has a great guide for engineering application.
