Function Block Diagram Approach for Manufacturing Process Control Programming

A process control language using function block diagram approach is designed for real-time control of continuous manufacturing process automation system, in which five groups of primitIVe functIon blocks and macro-type function blocks are defined to make an operator easy to implement target programs. To effectively utilize the proposed function block diagram language, a graphic editor, compiler and executer are also designed. The validity of the concept in its design and implementation is assured by on-line simulation in the multi-function controller designed for continuous process automation.

一种采用功能块图方法的过程控制语言被设计用于连续制造过程自动化系统的实时控制，其中定义了五组基本功能块和宏类型功能块，以便操作人员易于实现目标程序。为了有效利用所提出的功能块图语言，还设计了一个图形编辑器、编译器和执行器。通过在为连续过程自动化设计的多功能控制器中进行在线仿真，确保了其设计和实现理念的有效性。
