结合设计数控系统软盘驱动器数据传输系统的实践，详细论述了如何利用ＲＳ２３２接口及微型计算机并口，实现西门子８２０Ｍ系统数控程序的输入／输出。从正确传输数据以及方便操作等角度，分析了传输系统的功能设置；介绍了实现相应功能，该系统应具有的硬件结构及其原理；并分析、说明了软件设计中的要点和难点。
Combining with the practice of designing the data transmission system of the floppy disk drive of numerical control system, this paper discusses in detail how to use the RS232 interface and microcomputer parallel port to realize the input / output of Siemens 820M system NC program. The functions of the transmission system are analyzed from the perspective of correct data transmission and convenience of operation. The hardware structure and principle of the system should be introduced. The key points and difficulties in the software design are also analyzed and explained.
