摘　　要：介绍了智能气门电镦机的数据显示和命令输入的人机界面(HMI)和实现电镦机实时控制功能的下位计算机之间利用RS232串行接口的通讯程序的编写,以及实现硬件定时的原理和方法.实践证明,该系统人机界面美观、实时性能可得到保证,符合气门电镦的工艺要求.<Abstrcat> Programming of the serial communication between the host computer and the real time controller, which is used to transfer data and system parameters is described in detail in this paper. And an timer/counter card is introduced to give an exact timing of the real time controller. Practice proves that this system is of beautiful human computer interface and assured real-time property,meeting the technology demand for valve upsetting.
