【Abstract】 Several kinds of platforms for developing CNC machine tool control systems were investigated and compared. The conclusion is that: as a developing platform for Open-architecture CNC system, Windows CE is an ideal choice. The main point discussed in the paper is how to develop the device driver to implement the interrupt control for CNC system based on the Windows CE. Because CNC system is a typical kind of strong real time control system, its development involves both the kernel-mode and the user-mode of operating system. Taking CNC interpolating control as the example, the design technique of time-interrupt-driven device driver for IPC5387 PC timer card is introduced.更多还原
