工业过程控制 课程设计 题 目: 基于组态软件的流量比值过程控制系统设计 院系名称： 电气工程学院 专业班级： 自动 0901 学生姓名： 冯广森 学 号： 200948280112 指导教师： 王伟生 设计地点： 31517 设计时间： 2012.6.23--6.28 摘 要 随着科学技术的快速发展，人们对过程控制提出了更高的要求，在许多生产过程中，要求两种或两种以上的物料流量成一定的比例关系混合进行反应，对物料比例的要求甚为严格，如果不能满足要求，或是比例失和调，将会导致产品的质量达不到要求，以致造成损失，严重时会导致事故的发生.研究比值控制系统很有必要，提高比值控制系统的精度及水平具有深远的意义。 关键词：比值控制系统 组态王仿真 控制系统设计 应用程序 目 录 1 引言····································································1 2 设计目的与要求·························································· 2.1 设计目的······················································· 2.2 设计要求························································· 3 系统结构设计···························································· 3.1 控制方案·························································· 3.2 控制结构流程···················································· 4 过程仪表选择··························································· 4.1 流量检测传感器···················································· 4.2 电动调节阀····················································· 4.3 水泵·························································· 4.4 过程模块···················································· 5 系统组态设计························································· 5.1 组态图···························································· 5.2 组态动画··························································· 5.3 数据字典························································· 5.4 应用程序························································ 5.5 动画连接························································· 总结··································································· 参考文献································································· 1 引言 随着科学技术的快速发展，人们对过程控制提出了更高的要求，在
