摘要
传统数控系统的人机界面采用编程方式实现,不利于修改和扩展功能,并且用户体验较差。通过对现有蓝天数控系统"GJ301"的体系结构和基本功能的分析研究,设计了在局域网内监控数控系统的上位机控制系统。上位机采用嵌入式WINCE操作系统和MCGS嵌入版组态软件,人机界面的设计主要用MCGS提供的绘图工具箱来完成。上位机通过ModbusTCP协议向数控系统发送命令和采集信息。在数控系统任务控制模块的每个任务周期里通过单独的线程维护远程连接,解析执行命令并反馈结果。经过测试,该监控功能运行良好且操控更加简便灵活。
The traditional man-machine interface of numerical control system is realized by programming,this is not conducive to modify and extend the functionality,and has poor user experience. This paper analyzed system structure and basic functions of the existing blue sky NC system ' GJ301 ',and designed the Monitoring and Controlling function of CNC in the local area network. The host computer control system adopts the embedded WINCE operation system and MCGS configuration software in embedded version. Human machine interface is designed using the toolbox of MCGS. The host computer sends commands to CNC and collects information from CNC through Modbus TCP protocol. CNC system 's task control module is responsible for maintaining remote connections,parsing and executing commands and giving feedback to the CNC system through a separate thread in each task cycle. Testing results showthat this monitoring function works well and the manipulation of CNC through it is more easy and flexible.
