分析了ICMMS框架下维护子系统的目的、构成和特点。在参照ICMMS的一般分析和设计方法的基础上,以水电厂水轮发电机组调速系统的电液伺服机构为例,提出了分析与设计维护系统详细的方法与步骤。其目的是为在进行控制—维护—技术管理系统集成过程中,提供一种规范的、实用的、系统化的分析与设计维护子系统的方法。其基本思想是用户需求驱动、功能分解、逐步细化与具体化 Analyzes the purpose, constitution and characteristic of maintaining subsystems in ICMMS framework. Based on the general analysis and design method of ICMMS, taking the electro-hydraulic servo of hydraulic turbine governor system of hydropower plant as an example, the detailed methods and steps of analysis and design and maintenance system are put forward. Its purpose is to provide a standardized, practical and systematic method for analyzing and designing the maintenance subsystem in the process of integration of control-maintenance-technology management system. The basic idea is user-driven, functional decomposition, and gradually refine and specific
