用于弧焊跟踪的IBM PC/XT接口及控制线路设计

IBM PC/XT Interface and control circuit Used in Arc Welding Tracking System

本文主要论述了弧焊跟踪用IBM PC/XT接口及控制线路的设计过程,对步进电机的控制单元也进行了详细说明。介绍了设计过程中所采用的抗干扰技术。实践证明,本线路结构简单、工作可靠。

The design course of the interface plate on IBM PC/XT and the control circuit in the are welding seam tracking is discussed in detail ,in the meamwhile the control unit of the steping motors is illustrated. The antijamming technique used in the design is introduced too. The practices prove that the interface plate and the control circuit are simple and reliable.
