Abstract

The invention discloses a double DSP embedded type welding process visual feedback control system for welding seam tracking and welding quality control in welding automation, comprising a DSP image processing module, a DSP feedback control module, a power and reset module, a visual interface module, an analog video coding module and a USB control module. The DSP image processing module extracts the eigenvalues of a welding region image transmitted from the video interface module and transmits to the DSP feedback control module, the DSP feedback control module outputs corresponding signals according to the eigenvalues, and finishes close-loop control of welding seam tracking and welding quality. By this invention, welding seam tracking and welding seam shaping control can be carried out without a host computer.

Description

technical field

[0001] The patent of the invention belongs to the field of welding equipment, and specifically relates to a dual-DSP embedded welding process visual feedback control system for realizing welding process automation, welding process monitoring, welding seam tracking and real-time control of welding seam formation. Background technique

[0002] The visual sensor based on the industrial CCD camera is widely used in the image monitoring of the welding process, weld seam tracking and weld seam forming closed-loop control because of its large amount of information, high measurement accuracy, and no contact with the workpiece. Vision sensors are not easily affected by magnetic deflection or wire bending during use, but they need to overcome interference such as arc light, smoke, and spatter during welding. In addition, pattern recognition and real-time requirements for features such as grooves, arcs, and molten pools have put forward higher requirements for image pro...
