Research On An Embedded CNC System Based On ARM-WinCE

Now the embedded technical development progresses by leaps and bounds, theembedded system obtains the widespread application in very many industries and ischanging these industries gradually. The embedded technical development similarlyalso affected the numerical control technology development. The paper summarizedthe current state of Open-Architecture CNC system at home and abroad and hasanalyzed several kind of mainstream Open-Architecture CNC system architecturegood and bad points. Then proposed an idea of developing a prototype systembased on the ARM-WinCE CNC system made use of ARM processor and WindowsCE operating system.The paper discussed how to build ARM-WinCE CNC system's hardwareplatform based on S3C2410 development board and software platform based onWindows CE.Net. Construction CNC kernel on the ARM microprocessor based onthe Windows CE operating system, and the use of VIVI Boot Loader customizedimage loading to S3C2410 development board the same time.This paper focused on the ARM processor chip, using stream interface driverprogram structure to achieve a Bluetooth serial port driver development, achievedBluetooth communication between machine controller and mobile controller inARM-WinCE CNC system. Researched on how to use PWM timers of the S3C2410processor and Windows CE interrupt mechanism to progress the CNC systemreal-time control.
