一种通用测试系统故障诊断功能设计

A Fault Diagnosis System Design for General Test Platform

为了解决运载火箭测试过程中测试项目多、测试流程复杂、测试时间长的问题,一般采用具有故障诊断功能的通用测试系统,实现自动化测试;通过综合分析运载火箭测试项目需求,研究通用测试系统运行过程对故障诊断功能需求,提出了一种通用测试系统故障诊断功能设计方案,包括故障诊断的系统架构、线路诊断、测试平台自检、测试流程监测、故障定位,以及信息应用等功能;通过该故障诊断功能设计,简化了测试项目,实现了运载火箭的快速自动化测试、性能监测与状态评估,保障火箭的安全可靠运行,并可为维修决策提供支持。

As the pre-launch testing process is very complex and the number of critical parameters and fault modes in monitor are quite large,which brings command staffs a lot of burdens and pressures coming from fault diagnosis,a general test platform with fault diagnosis is used in launch vehicles＇ pre-launch testing process.By a requirement analysis of diagnosis function for the platform,a fault diagnosis system for the platform is proposed in this paper,including system architecture,BIT,process monitoring,fault location,and information application.With this intelligent function,a quick automatic testing system can be used in pre-launch testing process,and efficient auxiliary information can be provided for maintenance decision making.
