基于PDA的惯性测量组合交互式诊断辅助系统设计

Design of PDA-based Interactive Diagnosis Assistant System for IMU

为了实现对惯性测量组合的快速故障诊断,设计出以PDA作为操作平台的交互式故障诊断辅助系统;在对惯性测量组合的结构和功能进行深入分析的基础上,利用基于多信号模型的TEAMS软件对惯性测量组合进行建模并生成优化的诊断策略,并将所建模型和XML格式的诊断策略文件导入到PDA中;依据测试过程中每一步的结果,采用C#2.0语言对XML格式文档的诊断策略进行解析,从而提取出下一步的测试内容或诊断结果,指导完成诊断过程,实现故障的有效隔离;该系统具有实现简单、交互式快速诊断和便携的特点。

In order to locate the fault components of Inertial Measurement Unit（IMU） quickly,an interactive fault diagnosis assistant system based on PDA is designed.After profound study of the structure and function of IMU,its multi-signal model is built using TEAMS,by which the optimal diagnosis strategies are created.With C#2.0 language,the system which use PDA as operation platform stores the information of the built model and extracts the diagnosis instruction from the XML format diagnostic strategies documents and accomplishes the interactive diagnosis.This system is able to generate the test guidence according to the actual result of test,which is interactive,simple,quick and portable.
