摘 要：
A design scheme of motion control system based on parallel port of computer was proposed.The scheme adopts a multifunctional control board Y3002 based on the EPP protocol of a parallel port on computer.The use of Y3002 simplifies the structure of the system as well as minimizes the hardware of this system with the lowest cost.The strong real-time tool RTX(Real-Time Extension)was imported for its high-precision timer function and capability of direct access to the hardware.The application software of fore-and-after structural models is programmed with VC++ 6.0,and runs on Windows 2000 embedded with RTX.The system can also compile NC code.
