Problems solved by technology

However, this identification method has the following disadvantages: (1) Due to the harsh underwater environment, the image of the workpiece transmitted remotely is often blurred, which affects the judgment of the position of the weld; (2) Since the image of the workpiece is transmitted without image processing , the amount of transmitted data is too large, but the effective data is less; (3) The underwater camera is always in the shooting state, wasting limited underwater power

Embodiment Construction

[0017] The embodiments of the underwater weld automatic identification system of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] With the increasing shortage of land resources, people began to focus on underwater development. Underwater resources include marine resources and inland river resources. Due to the harshness of the underwater environment, only by improving the maturity of underwater welding technology can it be accelerated. Underwater resource development speed, so as to obtain more economic benefits.

[0019] There are three kinds of traditional underwater welding: dry method, wet method and partial dry method. Dry welding uses a large air chamber to cover the weldment, and the welding operator performs welding in the air chamber, which has the advantages of good safety, but has great limitations and is not widely used. Wet welding is that the welding operator directly welds under water, instead of arti...

Abstract

The invention relates to an underwater welding seam automatic identification system. The underwater welding seam automatic identification system comprises an underwater light source, an underwater camera, control equipment and wireless communication equipment, wherein the underwater light source is used for providing a light source for underwater shooting of the underwater camera, the underwater camera is used for shooting a welding image of an underwater workpiece when the workpiece is welded, the control equipment is connected with the underwater camera for carrying out image processing on the welding image and recognizing a welding seam of the welding image of the workpiece, the wireless communication equipment is arranged on water, is connected with the control equipment by an underwater cable and is used for receiving the welding seam of the workpiece and sending the welding seam of the workpiece to a water computer wireless. According to the underwater welding seam automatic identification system, the welding seam can be automatically detected in a severe underwater environment, and the automatic identification system can provide reliable reference data for the water computer to realize underwater welding operation control.

Description

technical field [0001] The invention relates to the field of underwater welding, in particular to an automatic identification system for underwater welding seams. Background technique [0002] Underwater welding is an indispensable and important technological means in the installation and maintenance of underwater engineering structures. This process is often used in marine salvage, marine energy, marine mining and other marine engineering and construction of large underwater facilities. [0003] In the process of underwater welding, due to the particularity of the underwater working environment, the construction party usually uses an overwater computer control system that is separated from the water surface to control the underwater welding equipment. For example, the positions of the welding equipment and the workpiece to be welded are determined and moved to each other. , Determination of welding gap and control of welding operation, such a remote control method is conve...
