摘要
以自主开发的基于Freescale HCS08的运动控制嵌入式系统为平台,以用户对数控工作台的需求为基础,采用统一建模语言UML建立数控工作台下位机用例图,根据对用例图的分析建立系统下位机状态模型,明确各个状态模型之间相互转移的条件和约束关系,并对软件总体流程做较为严谨的设计,使设计出来的下位机程序不仅能够满足用户对系统功能的需要,而且具有较高的可靠性和可维护性。
Based on Freescale HCS08 and based on self-exploitation embedded motion control system as a platform, researched on users＇ requirement to digital workbench as foundation, design a lower computer case diagram with unified modeling language （UML）. By analyzing case diagram, set up system lower computer status model. Define the condition of shift and connection among each status model. Besides, make a precise design for software flow as a whole to insure the software that is high reliability and simple maintainability satisfy users＇ requirement.
