【摘要】 图形系统是组态软件的一个重要组成部分,它以图形方式对控制系统现场环境中客观存在的事物进行模拟,并且建立它们之间的信息关系,形成简洁、直观、生动的现场背景和工艺流程图以及用户与系统之间的交互图。本文结合实际项目的任务需求,在参考国内外成熟组态软件的基础上,选择工厂模式对软件的主体结构进行设计,保证了系统的一致性和可扩展性。组态软件图形开发系统界面友好,操作简便,与运行系统连接紧密。更多还原

【Abstract】 The graphics system is an important component of configuration software.The system abstracts concrete objects in the control field using graphics mode,builds the relationship of them,and forms technique flow chart and mutual view between users and system in the end.Considering the demand of the customer and referring excellent configuration software in the world,this paper chooses Factory Method from several classical methods to design the framework of the software.The methods applied in this paper assure consistency and opening of the system.The graphical system is a configuration software with friendly interface and easy to be used.更多还原
