【摘要】 本文提出一种“软仪表”组态法来实现复杂控制回路的生成。它是把各种算式和功能模块化,做成“软仪表”,用户只要填入适当的组态字,象常规模拟仪表一样连接起来。而且“软仪表”的连接可直接在CRT屏幕上进行,不需要另加任何硬件和软件。本法比常用的过程控制语言、会话型表格语言等组态方法具有形式简单,直观醒目,使用方便等优点。经有关工厂实际使用,效果良好。更多还原

【Abstract】 A new concept of program configuration based on "soft-instrumentation" for process control is presented in this paper. The basic programming blocks corresponding to applied control algorithms are developed and they can be linked according to user’s requirement. What users have to do is to choose and key in configuration words with the help of CRT. The technique has been applied in a industrial plant with satisfaction, having main features of simple configuration formation and easy operating function.更多还原
