模糊故障诊断技术在视频矩阵故障诊断中的应用研究

数字视频矩阵是显控系统中实现信号引接与呈现的核心环节,复杂电子设备的特性导致了对其进行故障诊断时数学模型难以建立的难题。模糊故障诊断技术基于现有知识体系,通过采样对比的方法,绕过数学模型的建立过程,巧妙的解决了复杂电子设备的故障诊断问题,是适合视频矩阵故障诊断的有效方法。

Digital Video Matrix is the core part of the display and control system to realize signal connection and presentation. The characteristics of complex electronic equipment make it difficult to establish mathematical models for fault diagnosis. Fuzzy fault diagnosis technology is based on the existing knowledge system. It skiUfuUy solves the problem of complex electronic equipment fault diagnosis by sampling and comparing, bypassing the process of establishing mathematical model, and is suitable for video matrix fault diagnosis.
