摘要
设计了基于DSP的运动控制器的硬件系统,主要包括以下部分:DSP运动控制电路、编码器信号采集电路、PCI总线接口电路。用可编程逻辑器件EPM570搭建光电编码器的信号采集和计数处理电路,增强系统抗干扰性;同时对运动控制器进行光电隔离处理,减少了外界电路信号对运动控制器的干扰。
In this paper,the hardware circuit of Motion Controller based on DSP is designed which is composed of motion-control circuit,signals acquisition circuit for Encoder and PCI bus interface circuit.PCI bus interface circuit is realized by bus interface chip PCI9030 dedicated to the embedded system;Signals acquisition circuit for encoder and counting process circuit is built by PLD EPM570 to improve anti-interference ability.At the same time,Photoelectric Isolating is used in this system in order to cut down the jam from outer circuit.
