远程故障诊断系统中的故障信息研究

现有远程故障诊断系统常集中于对系统诊断模式和方法研究。结合信息理论和系统理论的观点，以故障信息为研究的出发点，指出远程故障诊断系统是一个完整的信息处理过程，研究并分析了信息获取的几种常用方式，给出了信息获取的一般模型。指出在网络带宽有限、故障信息庞大的情况下需要合理优化信息、合理配置资源和传输任务。研究表明在远程故障诊断中对故障信息的研究是系统的根本，立足于信息处理的观点和方法来考虑问题将有益于系统高效合理的运行。

A Research on Fault Information in Remote Fault-Diagnosis System

The research on the remote fault-diagnosis system in existence is often centered on the diagnosis model and method. Here, following the viewpoint of information theory and system theory and taking the fault information as a beginning, it is pointed out that the remote fault-diagnosis system is a complete process of information processing. Through researching on and analyzing several ways of information acquiring, a general model of information acquiring is presented. Moreover it is pointed out that reasonable information optimizing, resource configuring and mission transporting are important and necessary on condition that the network band-width is limited and the fault information is of huge amount. The present research shows that the studying of fault information is the basis or core of the system in remote fault diagnosis, and it is helpful to the effective and reasonable operation of the system to consider problems from the viewpoint and method of information processing.
