摘要
针对当前软件无线电系统故障诊断时间长、诊断结果精度不高、诊断过程复杂等问题,开发了故障诊断平台。该平台以MFC框架为基础进行开发,对系统的建模分析信息以及实时运行状态信息利用数据库进行储存,集中实现了实时诊断和拉格朗日两种故障诊断算法,用户可以选择对应的诊断算法对系统进行诊断。该平台能够直观地给出两种诊断算法的诊断结果及诊断过程需要的时间。平台以快速、准确、方便为目标,详细论述了一种实用可靠的软件平台设计方案,并通过故障实例验证了该平台的实用性。
Aimed at the problems of the longtime of fault diagnosis,the low precision of fault diagnosis and the high complex of diagnosis process in the current poor testability of software radio systems,a fault diagnosis platform was developed. The platform was developed based on the MFC framework and a database was used to store the modeling and analysis information and real-time operational status of the circuit,and the real-time diagnosis algorithm and Lagrangian diagnosis algorithm were concentrate realized. The users can select the corresponding diagnosis algorithms for the system diagnostics. Using this platform we can directly find the results of two diagnosis algorithms and the time they cost. This platform is fast,accurate and convenient. A practical and reliable platform design was discussed in detail,and the practicability of the platform was demonstrated by fault example.
