基于开放式数控系统的辅助控制系统设计

摘要

In order to assist the open CNC system to complete the peripheral port control and NC function instruction customization, a special auxiliary control system is designed on the basis of the study of the PLC control system. The system uses the virtual PLC technology, VC++ development platform, designs the open command parser and operation system. By defining binary encoding rules and directives resolution table , it achieve NC sub function instruction development. The system function is independent of the main control system function. It is proved by the practical application that the auxiliary system can control the port state according to the loading PLC program and successfully operate the NC sub function.%为辅助开放式数控系统完成外围端口控制及数控功能指令订制,在研究了PLC控制系统的基础上,设计一种专用辅助控制系统.该系统采用虚拟plc技术,VC++开发平台,设计开放的指令解析器和运行系统,通过定义二进制编码规则和指令解析表实现数控子功能指令拓展.该系统与主控制系统功能独立,经过实际应用证明,该辅助系统能够根据加载的PLC程序控制端口状态,并成功运行数控子功能.
