基于FPGA的开放式数控系统硬件配置设计

摘要

According to the reconfigurable requirement of open CNC system. this paper sums up and analyzes the feasibility of the hardware-reconfigurability based on the architecture of PC+ programmable I/O board. Meanwhile, the modular design based on FPGA is used to estabish its module. According to hardware description language, the main modules are designed.The open CNC system is verified through the simulation software and its application.This system meets the requirement of the hardware reconfigu-rability.%根据开放式数控系统的配置要求，在PC+可编程I/O卡的体系结构的基础上，总结分析硬件可配置的可实现背景，采用模块化的思想提出并建立了基于FPGA平台的硬件可配置模型。利用硬件编程语言完成重要模块的设计，分析了仿真结果验证设计的可行性与有效性。在自行研制的开放式数控系统上完成了四轴配置的验证，达到了开放式数控系统硬件可配置的要求。
