摘要 提出了一种在大型关键生产环境中运用的基于实时状态的在线故障诊断模型(FDM),对原数据进行了形式化定义,对模拟量定义了一种多值逻辑的表示形式,使得开关量和模拟量能有效地统一起来.给出了故障诊断的知识表示形式和知识推理机制.初步实践证明该模型是有效的. Anon-line fault diagnisis model based on the real-time status in a large important production en- vironment is presented in this paper. The basic data is defined formally. All kinds of the parameters are defined as a multi-logical value that is very usefull for the description in one form used by the related mod- el. The knowledge presentation and the inference machanism are given. The model is proved to be effec-tive.
