摘要
针对埋弧自动焊过程控制及焊接操作控制的特点和工艺要求,在MZ-1250晶闸管式埋弧自动焊机主电路的基础上,设计了以TMS320F2812为核心的埋弧焊数字控制系统,并设计了埋弧自动焊机数字控制系统的外围硬件电路,硬件电路主要包括焊接电流采样电路、同步和晶闸管触发电路及保护电路等.本文重点阐述电路的设计思想、硬件结构及工作原理.
According to the characteristic of SAW, this paper designed the digital control system for SAW on the base of the main circuit of MZ-1250 SCR automatic SAW machine, and the control core was TMS320F2812. The paper had designed the system circuit for the digital control system for submerged-arc welding machine. The system circuit contained welding current sampling circuit, synchronization and trigger circuit, protection circuit, etc. In this paper, the design idea, hardware architecture, working principles were explained.
