摘要
有限状态机(FSM)技术是任务调度的核心,通过分析STEP-NC数据流和STEP-NC程序的数据模型,提出FSM的STEP-NC信息提取系统实现方案。把信息提取系统分为节点-实体模块、词法分析模块、实体-实例模块、检索模块和特征重构模块五个模块,在创建节点和字典实体数据的基础上,对基于FSM的五个模块的内部任务处理进行研究,最终得到三维实体几何数据。在Visual Studio 2005平台上开发信息提取系统,并通过实例对其有效性进行验证。
Finite State Machine （FSM） technology is the core of the task scheduling, by analyzing the STEP-NC data flow and da ta model of STEP-NC program, present the STEP-NC information extraction system proposed FSM implementation. Information ex traction system is divided into nodes-entity module, lexical analysis module, entity-instance module, retrieval module and features reconfigurable module five modules ,based on creating nodes and dictionary entity data, to research the five modules that take the FSM internal task processing, by the end of each module handles, to get the 3D solid geometry data. Information extraction system is developed in Visual Studio 2005 and its effectiveness was verified by one example.
