基于PCI总线的电火花线切割机运动控制卡设计

A Design Of Motion Controller For WEDM Machine Tool Based On PCI Bus

针对数控机床控制技术发展中的新要求,提出并设计了一种新型的控制方案,即运用PCI总线实现PC机与单片机的高速通讯,以提高控制效率和实时性,并应用CPLD解决了双口RAM的仲裁控制逻辑问题。

In order to fit the requirement of the development of NC＇s control system, a new control project has been advanced and designed, PCI bus is used to realize the high-speed communicationwith MCU in it, then improve the control efficiency and real-time character. And CPLD is used to solve the problem of dual-port RAM＇s arbitration and control logic.
