基于 PLC 的多工艺调度实现方法

摘要

为了提高生产效率，提出了基于PLC的多工艺调度实现方法。结合工艺参数，建立各工艺时间轴模型用以调度分析，针对多工艺并行过程中指令复杂的问题，在程序开发过程中应用了堆栈按序排列的数据结构特性，有效地实现了指令的连续性，并应用指针变量作为取指令的方式，解决了各工艺之间独立性的问题。应用结果表明，该方法有效地解决了多工艺调度的问题。%In order to improve production efficiency ,the realization method of multiple process scheduling based on PLC is put forward . In combination with the process parameters ,the model of process time axis is established for scheduling analysis .To deal with the complicated instruction question in the process of parallel process , the stack’ s data structure characteristic that the data are in ordered array is applied to the process of program development ,and the continuity of instruction is realized .The pointer variable is used as the instruction fetch way to solve the problem of the independence between processes .Application results show that this method solves the problems of multiple process scheduling effectively .
