针对当前软件开发中存在的需求变化大和可重用性差等问题 ,提出了一种基于COM技术的旋转机械状态监测与故障诊断系统软件开发方法。从领域分析的角度抽象出了系统的体系结构 ,提出了系统的组件化模型 ,并给出了组件的实现方法。 Aiming at the problems such as large demand and poor reusability in the current software development, a software development method of the condition monitoring and fault diagnosis system of rotating machinery based on COM technology is proposed. From the perspective of domain analysis, the system architecture is abstracted, the system component model is put forward, and the method of component implementation is given.
