[0002] Welding is generally a process of joining metal components by heating them; it is a technique that joins metal components by heating the joint area to locally melt them and forming a bond through a localized casting action. Filler material can also be molten and added to the locally melted area to facilitate the joining. With the advancement of robotic technology driven by research and development of safe welding techniques, automated welding devices have been developed to perform the process automatically and are being used on production lines, significantly contributing to increased productivity. However, skilled welders still perform direct welding in areas where automation is difficult. The problem to be solved

[0003] In the case of automated welding devices, setting welding conditions and monitoring the welding process is relatively easy because their operation is centrally controlled via computer technology along with typical movements; however, when welding is performed manually, the quality of the work can vary significantly depending on the operator's skill level. Although there is a need to monitor and manage this, it is practically difficult to monitor the process by separately measuring welding conditions along with the operator's irregular movements. Furthermore,

[0004] Accordingly, various embodiments of the present invention aim to automatically recognize the work process at a site where welding is performed by a welding operator and provide status information of the welding process. means of solving the problem

[0006] And the above-mentioned location recognition unit can recognize the location of the welding machine used by the welding worker at the site, and at least one welding point where welding is required by the welding worker.

[0007] In addition, the position recognition unit can acquire at least one image including the shape of the welder and the object to be welded through at least one camera, and recognize the position of at least one welding point of the welder and the object to be welded through the at least one image.

[0008] In addition, the position recognition unit can acquire at least one image through a plurality of cameras positioned at a location where at least two cameras can capture each of the at least one welding point.

[0009] In addition, the position recognition unit can recognize the position of each of the welder and at least one welding point through designated marks marked on each of the welder and at least one welding point on the at least one image.

[0010] In addition, the welding status determination unit may determine that welding is completed at one welding point if it exists within a specified distance from one of the at least one welding points.

[0011] In addition, the welding status determination unit may determine that welding is completed at the one point when the welding machine is within the specified distance from the one point and the operating state for welding of the welding machine is confirmed through a measuring instrument.

[0012] In addition, the welding status determination unit can determine that welding is completed at the one point if, while the welding machine is within the specified distance from the one point, it is confirmed through an image acquired by the position recognition unit to recognize the position of the welding machine that the torch light of the welding machine has been generated.

[0013] Additionally, it may further include an interface section for providing the generated state information to a welding operator who welds the at least one welding point using the welding machine.

This enables the welding work to be managed accurately and quickly, as in an automated welding environment, in an irregular welding environment where a welding operator directly welds the welding points using a welding machine.

[0016] In addition, the welding management system can provide a service for the integrated management of the welding process by providing information on the progress status confirmed during the welding operation management process to a remote welding manager via a network, providing guide information for each welding point to a welding operator based on information recognized during the management process, and continuously building a database (DB) storing information necessary for the welding operation using data acquired during the welding process.

According to one embodiment, at least one camera (10) is installed at a designated location at the site (1) to photograph the workpiece as a whole. The designated location may be, for example, a location where all points requiring welding (or welding points) on the workpiece can be photographed.

[0028] According to one embodiment, the welding management system (100) can recognize a welder (20) and a welding object through at least one camera (10).

According to one embodiment, the welding management system (100) can recognize the location of at least one welding point of the welding object. This will be explained in more detail in FIG. 3.

[0029] According to one embodiment, the welding management system (100) can determine whether welding is completed based on the location of the recognized welding target and the welding machine (20). For example, if the welding machine (20) is within a specified distance from a specified welding point of the welding target, it can be determined that welding is completed at the welding point.

[0030] According to one embodiment, the welding management system (100) can determine whether welding has been completed at the welding point by checking the operating status of the welding machine (20) while the welding machine (20) is within a specified distance from the welding point of the workpiece. For example, the welding management system (100) can determine that welding has been completed at the welding point if the operating status for welding of the welding machine (20) is confirmed through the measuring instrument (30) while the welding machine (20) is within the specified distance.

[0031] According to one embodiment, the measuring instrument (30) can be connected to the welding machine (20) to measure the output of the power supply. According to one embodiment, the data measured by the measuring instrument (30) can be uploaded to a cloud service. For example, data representing electrical characteristics such as voltage (V), current (A), and output (W) measured during welding operations can be uploaded to a cloud service.

[0032] According to one embodiment, the welding management system (100) can track the location recognized according to the movement of the welder (20) during the welding process and sequentially identify the points where welding is completed. For example, the welding management system (100) can identify the points where welding is completed among a plurality of welding points of a welding object.

[0033] According to one embodiment, the welding management system (100) can provide information about points where welding has been completed to the welding operator. For example, the welding management system (100) can provide information about points where welding has not been performed, along with points where welding has been completed. Accordingly, the welding operator can weld the points where welding has not been completed.

[0034] According to one embodiment, the welding management system (100) may be connected to a welding integrated management platform server (200) via a network. According to one embodiment, the welding integrated management platform server (200) may provide platform services for integrated management of welding processes performed at the site (1).

[0035] According to one embodiment, the welding integrated management platform server (200) can provide welding guide information for a welding target. For example, the welding integrated management platform server (200) can provide information necessary for welding, such as the output of a welding machine, welding direction, welding inclination, welding speed, and spacing between torches, for each welding point of the welding target.

[0036] According to one embodiment, the welding integrated management platform server (200) can store data of welding work performed at the site (1) in a database (DB). For example, the welding integrated management platform server (200) can store data uploaded to a cloud service in the database (DB). The data may be, for example, data regarding values ​​measured by a welding machine during welding. According to one embodiment, the welding integrated management platform server (200) can store the data in the database (DB) along with information about the welding point where welding was performed. The information about the welding point may be received, for example, from the welding management system (100). According to one embodiment, the welding integrated management platform server (200) can learn from the data stored in the database (DB) to generate guide information for a designated welding point. The guide information may be provided to a welding worker, for example, through the welding management system (100).

[0037] According to one embodiment, the welding integrated management platform server (200) can receive information regarding the progress status of the welding process performed at the site (1) from the welding management system (100). For example, the welding integrated management platform server (200) can receive information regarding the points where welding is completed among the welding points of the welding target. According to another embodiment, the welding integrated management platform server (200) can process information necessary to manage the welding process performed at the site (1). According to one embodiment, the welding integrated management platform server (200) can perform some of the processing steps of the welding management system (100) described above. The said processing steps may be difficult to process at the terminal of the welding management system (100), for example. According to one embodiment, the welding integrated management platform server (200) can perform an operation to recognize the welding machine (20) and the welding target by analyzing an image acquired through at least one camera (10). Accordingly, the welding management system (100) may manage the welding process through the integrated management platform server (200).

[0038] According to one embodiment, the welding integrated management platform server (200) can provide information regarding the progress status of the welding process to the welding manager through the remote management system (300).

[0040] Referring to FIG. 2, the welding management system (100) may include a position recognition unit (110), a welding status determination unit (120), a status information generation unit (130), and an interface unit (140).

[0041] According to one embodiment, the position recognition unit (110) can recognize the location of at least one welding point that requires welding on a welding machine (20) and a welding target (not shown). According to one embodiment, the welding management system (100) recognizing the welding machine (20) may mean recognizing the real-time location of the welding machine (20) moving to weld the at least one welding point in the present invention for managing the welding procedure. According to one embodiment, the welding management system (100) recognizing the welding point is recognizing the location of the welding point on the welding target, and the recognized location itself may be an element that can identify the welding point.

[0042] According to one embodiment, the location recognition unit (110) can recognize the location of a welding machine (20) used by a welding worker at a site (e.g., site (1) of FIG. 1) and at least one welding point that requires welding by said welding worker. In other words, the welding management system (100) can manage the welding process in which a welding worker at a site uses a welding machine (20) to weld said at least one welding point.

[0043] According to one embodiment, the position recognition unit (110) can acquire at least one image including the shape of the welder (20) and the welding target through at least one camera (10) to recognize the welding point of the welder (20) and the welding target. For example, the position recognition unit (110) can acquire a real-time image during the welding process at at least one welding point of the welding target. The real-time image may include, for example, the real-time shape of the welder (20) moving to each welding point.

[0044] According to one embodiment, the position recognition unit (110) can recognize the location of the welder (20) and at least one welding point of the object to be welded through the at least one acquired image. For example, the position recognition unit (110) can recognize the location of the welder (20) and each of the at least one welding point through designated marks marked on the welder (20) and each of the at least one welding point on the at least one image. The designated marks may be marked separately to recognize the welding point and the welder (20), for example, or may consist of a designated part of the object. This will be explained in more detail in FIG. 3.

[0045] According to one embodiment, the welding status determination unit (120) can determine whether welding is completed at the at least one welding point based on the at least one welding point and the recognized position of the welder (20). For example, the welding status determination unit (120) can determine that welding is completed at the one welding point if the welder (20) is within a specified distance from one of the at least one welding points. This will be explained in more detail in FIGS. 5a, 5b, and 5c.

[0046] According to one embodiment, the welding status determination unit (120) can determine whether welding is completed at the at least one welding point by checking the operating status of the welding machine (20) together with the recognized location.

[0047] According to one embodiment, the welding status determination unit (120) can determine whether welding is completed based on the operating status of the welding machine (20) confirmed through the measuring instrument (30). For example, the welding status determination unit (120) can determine that welding is completed at one point if the operating status for welding of the welding machine (20) is confirmed through the measuring instrument (30) while the welding machine (20) is within a specified distance from one of the at least one welding points. The operating status for welding may be, for example, a state in which an output greater than a specified amount is applied from the power supply of the welding machine (20) to weld the welding point.

[0048] According to another embodiment, the welding status determination unit (120) can determine whether welding is completed based on the operating status of the welder (20) confirmed through an image obtained through at least one camera (10). For example, the welding status determination unit (120) can determine that welding is completed at one point if it is confirmed through the image that the welder (20) is within a specified distance from one of the at least one welding points and the welder (20) is present. The image may be, for example, an image obtained to recognize the position of the welder (20) by the position recognition unit (110). Accordingly, the operating status of the welder (20) can be checked without the need to obtain data through the measuring instrument (30).

[0049] According to one embodiment, the welding status determination unit (120) may determine that welding is completed at a welding point if the specified operating state of the welding machine (20) is maintained for more than a specified time. For example, the welding status determination unit (120) may determine that welding is completed if the operating state of the welding machine (20), which is confirmed through a measuring instrument (30) or an image, is maintained for more than a specified time. The specified time may vary depending on the welding point, such as the length, number of welds, material, etc., as the minimum time required to weld. According to one embodiment, the welding status determination unit (120) may receive information regarding the specified time through a server (e.g., the welding integrated management platform server (200) of FIG. 1). The welding status determination unit (120) may request the specified time information of a welding point close to the welding machine (20) from the server.

[0050] According to one embodiment, the state information generating unit (130) can generate state information for a point determined to be completed among at least one welding point of a welding target.

[0051] According to one embodiment, the interface unit (140) can provide the generated status information to a welding operator who welds at least one welding point of a workpiece using a welding machine (20). The status information can also be provided to a welding manager located at a remote location, for example.

[0052] Accordingly, the welding management system (100) can manage the welding process performed on-site.
