    摘要:

    针对当前广泛使用的基于PC的数控系统存在的不足,提出一种基于嵌入式技术和微处理器的高实时性、多任务的嵌入式数控转塔冲床数控系统。为满足数控转塔冲床对实时控制的要求,嵌入式操作系统选用WinCE7,硬件平台由CORTEXA8微处理器和FPGA组合而成。分析了计算机与数控机床之间通信方式的现状和对高效加工自动化的影响,提出了基于ZigBee的数控转塔冲床无线通信方案并介绍了数控系统实时控制的实现。结果表明:ZigBee模块通信正常,能实现上位机与嵌入式控制器之间的数据收发,降低了企业成本,提高了生产效率。

    Abstract:

    In view of the existing problems of CNC system, which is based on PC and widely used in the industry, this paper puts forward a high real time performance and multi task embedded CNC turret punch press system based on embedded technology and a microprocessor. In order to meet the requirements for the real time control of CNC turret punch press, WinCE7 embedded operation system and the hardware platform based on CORTEXA8 microprocessor and FPGA are selected. The current situation of communication between computer and NC machine tool and its impact for the high efficient processing automation are analyzed, and the wireless communication scheme based on ZigBee of CNC turret punch press is proposed in this paper. The implementation of real-time control of CNC system is introduced and the experimental results show that the ZigBee module could realize normal communication between PC and embedded controller, data interaction and low business costs, and it could improve production efficiency as well.
