A Fault Diagnosis System Design for General Test Platform

摘要:

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。

Abstract:

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.
