2、位控制的应用非常普遍，从简单的浮球液位开关、非接触式的超声波液位检测一直到高精度的同位素液位检测系统到处都可以见到他们的身影。而控制的概念更是应用在许多生活周遭的事物上。而且液位控制系统已是一般工业界所不可缺少的元件。凡举蓄水池，污水处理场等都需要液位元的控制.如果能通过一定的系统来自动维持液位的高度那么操作人员便可轻易地在操作时获知真个设备的储水状况,如此不但工作人员工作的危险性,同时更提升了工作的效率及简便性.基于智能仪表的水箱液位控制系统正是具有这种功能。本课题利用智能仪表控制系统，结合组态王监控软件设计人机对话界面，实现水箱液位自动控制系统设计。通过对现场系统数据的采集处理，在组态王中
3、实现动画显示、报警处理、流程控制、实时曲线和报表输出等功能。同时利用智能仪表控制系统，在所设计的组态王监控界面中，进行相关仪表调校和控制器参数整定。最后向用户提供锅炉过热蒸汽控制系统的动态运行结果。关键词：液位控制；智能仪表；组态王盐城工学院本科生毕业设计说明书( 2011)The Simple Control System Desigm of the Intelligent Instrumeng Based on ConfigurationAbstract: With production levels and the development of science and technolog
