双丝窄间隙埋弧焊微机控制系统的研究

本文采用ＭＣＳ—５１单片机，利用双ＣＰＵ分时主—从机技术，解决了双丝窄间隙埋弧焊系统多复杂信息量的处理要求所带来的技术难题，实施了该系统的微机控制，所研制的微机控制系统由ＥＰＲＯＭ、ＲＡＷ、Ｉ／Ｏ、ＣＴＣ、Ａ／Ｄ等专用芯片，ＬＥＤ显示，键盘矩阵，打印机，光电隔离等电路组成，系统可实现：焊接过程状态及焊接规范参数的预置并可以修改，在焊接过程中，对焊接规范参数进行实时检测，反馈控制并动态显示，定时自动打印焊按规范本好，以便存档记录，为厚壁压力容器的焊接质量检测提供了可靠的依据。该系统还可以实现环缝焊接时焊接线速度的控制。系统Ｉ／Ｏ口全部采用光电隔离，整机抗干扰能力强，功能齐全，结构合理，运行可靠。

Study on Microcomputerized Control System of Dual-wire Narrow-gap Submerged Arc Welding Machine

Control system of duai-wire narrow-gap submerged arc welder was developed with aMCS-51 single-chip microprocessor and it consisted of circuits of LED display,keyboard,printer and light-electronic couple,and IC chips of EPROM,RAM,I/O,CTC and A/D. The process contrul,reset anddisplay of welding parameters,welding speed control of circle seam and parameter printing could berealized. It was with strong ability of antijam,perfect functions,reasonable structure,good reliability.
