片上网络化运动控制器的设计与实现研究

该文针对现有运动控制器在网络化、体积和功耗等方面存在的不足,结合最新出现的SoC技术和嵌入式Internet技术,提出一种片上网络化运动控制器的体系结构,它支持基于Internet的远程运动控制功能,并在Altera公司推出的EPXA1开发板(可编程芯片Excalibur系列)上实现了它的原型系统:SoC_Eweb_step。SoC_Eweb_step采用SoC技术,将控制器的大部分功能在单个芯片上实现,具有功耗低、体积小的优点;采用分布式嵌入式Internet技术,通过在Excalibur芯片内嵌的处理器上运行嵌入式WebServer实现网络通信功能。

Research of Design and Realizaion on Networked and Single-chiped Motion Controller

Pointing to the shortcomings in network connectivity,size and power consumption of current motion controller,this paper does some research on the architecture of motion controllers by using system-on-chip technology and embedded Internet solutions and proposes a new motion controller architecture,featured with single-chip and network enabled.The new architecture supports long-distance movement control by Internet.In order to prove the feasibility of proposed architecture,a prototype,SoC_Eweb_step is built on EPXA1 development board(programmable chip Excalibur series)manufactured by Altera,Ltd.SoC_Eweb_step implements the most function of motion controllers on a chip by using system-on-chip technology and achieve the advantage in power consumption and size.It implements the function of network communications by running an embedded Web Server on the ARM embedded in Excalibur.
