摘　　要：针对市场上的小型数控系统,设计了一种基于Windows XP平台计算机并口的三轴轨迹控制系统.系统采用开环控制,控制部分主要通过软件实现.上位机与下位机模块通过并口通信,并口由独立编写的设备驱动程序驱动.重点介绍了设备驱动程序的通信过程.应用结果表明,系统响应速度快、数据处理能力强、稳定性好,且能同时适用于多种用途的数控系统.In view of traditional small numerical control system, a triaxial trajectory control system based on parallel port of Windows XP platform is designed. Open-loop was adopted and system control was realized mainly by software. Communication between PC and interface module of lower computer was realized by the parallel port,and the port was driven by developed device driver. Communicating process is introduced emphatically. Operating results show that its response speed is fast, data processing ability and stability is well and it can be applied to multi-purpose computerized numerical control system.
