系统分析了水电机组维护域知识的构成和获取方法,从用户及诊断决策系统的角度分析了设备知识数字化描述的必要性;提出了面向用户的知识多元数字化描述与集成方法,该方法将传统方法无法直接编码的设备层次、结构、故障、维护等知识编码化、可视化,并以设备层次知识为线索进行集成,提高了知识的可理解性、扩大了知识的共享范围,为建立水电机组故障诊断与维护决策系统奠定基础。
This paper systematically analyzes the formation and acquisition methods of knowledge of maintenance domain of hydropower units, and analyzes the necessity of digitization description of equipment knowledge from the perspective of users and diagnostic decision-making system. It proposes a user-oriented knowledge digitalized description and integration method, The coding, visualization of equipment hierarchies, structures, faults and maintenance codes that can not be directly coded are integrated into the clues of equipment level knowledge to improve the comprehensibility of knowledge and expand the sharing range of knowledge. In order to establish the fault diagnosis of hydropower units, And to maintain the decision-making system to lay the foundation.
