| 摘 要： | 功能块是实现现场智能仪表互操作、自诊断和自适应功能的基础。为了形式化地分析和模拟功能块及其构成的控制系统，本文建立了功能块的着色Petri网(CPN)模型。文中不但利用CPN模型分析了单一功能块内部的模式转换和参数状态传播过程，并且分析了功能块构成控制系统中的不同功能块的模式和参数状态之间的相互关系。基于功能块的锅炉水位控制系统应用过程的建模与分析表明，CPN模型完全胜任上述要求。

| Abstract: | Function Blocks (FBs) play important roles in interoperability, auto|diagnose and control of intelligent instrument. For effectively realizing and applying FBs and FBs based control system, Colored Petri Net (CPN) models of FBs are constructed, and through which the internal procedure of FBs and the relationship of mode and parameter status between different FBs are analyzed. The modeling and analysis of FBs based boiler control system indicates that CPN model is capable of graphically simulating FBs, and also normally analyzing their operation mechanism. |
