基于FPGA的硬件可重构数控系统的研制

Development of Reconfigurable Hardware NC System Based on FPGA

可重构要求是 2 1世纪制造系统的核心能力 ,为了实现数控系统的重构 ,提出了一种硬件实现方法 :将数控系统模块化 ,各模块采用硬件描述语言设计为数控 IP(NC Intellectual Protocol) ,通过数控 IP的集成完成数控系统的设计 ,改变下载到现场可编程逻辑器件中的配置数据来完成数控系统功能的重构。

Reconfigurability is an essential ability for manufacturing systems in the 21 century. This work presents a method using hardware to implement reconfigurability in NC systems. In order to construct the reconfigurable NC systems,those systems are modularized.Taking the advantage of hardware describe language,every module is designed as NC Intellectual Protocol that composes the whole NC system design. The NC systems thus can be reconfigured through changing the configuration in the field programmable gate array. An experiment about economical reconfigurable NC prototype is carried on to certify the feasibility of this method.
