安全级DCS算法组态图形——代码转换关键算法设计

Key Figure Design of Graphics-to-Code Conversion for Security-Level DCS Alogorithm Configuration

核电厂安全级DCS系统中,逻辑算法组态一般以图形的形式在工程师站完成,经过语言转换与交叉编译最终生成可执行文件下装到嵌入式设备中运行。本文分析了由图形语言转换为目标语言的过程,总结出其中如何快速、低耗获取组态对象关系和安全调度的关键问题,将其抽象为数学模型以图论的方法解决,基于图论基础理论完成由图形语言到计算机数据结构的转换,基于深度优先搜索算法与dijkstra算法实现了图形形式的算法功能块间的快速寻径与安全调度。

Nuclear power plant safety level of DCS system,the logic alogorithm configuration,generally in the form of graphics in the engineer station,after need to transform the resulting executable file bottoms with cross compiling to run in the embedded devices.This paper analyzes the process of into the target language by graphical,summarized how to quickly and low consumption for a configuration object relationships and scheduling,the key problems of the safety and the abstract for the mathematical model of graph theory methods to solve.Based on the basic theory of graph theory,the transformation from graphic language to computer data structure is completed.Based on depth-first search algorithm and dijkstra algorithm,fast path-finding and secure scheduling between graphical function blocks are realized.
