采用DSP控制的高效管道双焊炬全位置自动焊机研究

Research on high-efficient pipeline double-torch all-position auto-welding machine by DSP

结合国内外长输管道自动焊接技术的发展,从自动控制角度讨论了一种以DSP(高速数字信号处理器)为控制核心的管道双焊炬全位置高效自动焊机;介绍了DSP、CPLD和FPGA在自动焊机控制和逻辑电路中的设计开发应用;同时也介绍了该设备在管道根焊和高效焊接方面的应用。

Combined with the development of long distance pipeline auto-welding technics,this paper discusses a high-efficient pipeline double-torch auto-welding machine with DSP as core,introduces the design and application of DSP,CPLD and FRGA in automatic welding control and logic circuit.Also,the application of the new machine in pipeline root welding is introduced.
