摘　　要：为解决物流输送线上PLC编程方式工作量大、技术要求高的问题,设计图形化编程方法,应用于物流设备组线时替代PLC的自备单片机控制系统。通过对物流线运行原理的分析,确定了将流程图转换为控制指令的图形化转换方法,设计了编程平台的图形化资源,定义对应图元的相关参数。针对流程图逻辑表达不清的问题,提出一种结构优化的算法,先将控制程序流图抽象化为AOV图,使用邻接表的方式存储数据,再针对组合判断和循环两种控制逻辑对AOV图进行结构优化和深度遍历调整,最后输出控制指令,发送给下位机,由下位机按规定顺序执行控制指令。研究结果表明,该图形化编程方法能够实现流程图向控制指令的转化,将生成的控制指令下发给下位机后,下位机能够按照流程图的逻辑运行。In order to solve the problem of heavy workload and high technical requirements of PLC programming mode on the logistics conveying line,graphic programming method is designed to replace the self⁃provided single⁃chip microcomputer control system of PLC when applied to the logistics equipment group line.Based on the analysis of the operating principle of the logistics line,the graphic conversion method to convert the flow chart into the control instruction is determined,the graphic resources of the programming platform are designed,and the related parameters of the corresponding graph element are defined.To solve the problem of unclear logical expression of flow chart,a structure optimization algorithm is proposed.The control program flow graph is abstracted into AOV graph,and the data is stored in the way of adjacency list.The structure optimization and depth traversal adjustment are carried out on the AOV graph for the two control logics of combination judgment and cycle,and the control instruction is output and sent to the lower computer.The control instructions are executed by the lower machine in the specified order.The results show that the graphical programming method can realize the transformation of flow chart to control instruction.After the generated control instruction is sent to the lower machine,the lower machine can run according to the logic of flow chart.
