This paper describes the innovation schemes of the interface of a CNC machinewhich cannot communicate with a computer by a Direct Numerical Control(DNC)interface andthe functions of a DNC interface system.One architecture of hardware and software of a practi-cal single-chip computer based on DNC interface system developed by the authors is given.Without any change of the original hardware and software,this DNC interface system has beenused to innovate the CNC machine’s interface to implement the direct communication between acomputer and a CNC machine and to achieve no tape transmission of a part program and ma-chine parameters.It has been demonstrated that this DNC interface system has certain practicalvalues in improving the reliability,efficiency and production management of CNC/NC machine.

With the rapid progress of computer, microelectronics and information technology, the development of intelligent technology is getting faster and faster, higher and higher, and the application scope has been greatly expanded. Intelligent as a modern new invention, is the future direction of development, it can be in accordance with the preset mode in an environment in the automatic operation, does not need man-made management, can be applied to scientifi c exploration and other purposes. Intelligent electric car is one of the embodiment. Designers can program their software to achieve their travel, tracking, stop the precise control and detection of data storage, display, without human intervention. Therefore, the intelligent electric car with reprogramming characteristics, is a kind of robot. The design uses AT89C51 single-chip motor drive circuit and infrared remote control and tracking module and infrared receiver integrated sensor designed, the use of modular design, the use of infrared remote control car forward, back, turn left, turn right, Start and stop.

With the rapid development of computer technology, microelectronics and related technologies, embedded systems are being applied to more and more fields. In industrial control, especially in motion control, the complex control and processing, in the past more use of industrial computers and PLC as a processor. However, there are many disadvantages to the use of industrial computers and PLCs in smaller applications such as mobile robots. The embedded motion control system based on microprocessors and embedded Linux is small in size, has strong processing power and fl exibility. More and more applications. In this paper, we study the motion control system based on embedded Linux. The host computer built by Intel Xscale architecture microprocessor PXA255 adopts the embedded Linux operating system. The DC motor digital servo control board constructed by AT89S52 is used as the lower motion control unit, which communicates through the serial interface to form a movement Control System.
