[0002] In the welding industry, continuous technological advancements and increasing sophistication of welding processes are driving higher requirements for real-time monitoring of welding process parameters, welding machine control, welding parameter query, and welding knowledge learning. Traditionally, real-time monitoring of welding process parameters and welding machine control rely on manual recording and on-site operation, respectively. This results in low efficiency, poor data accuracy, and difficulty implementing remote monitoring and data analysis. Furthermore, welding parameter query and welding knowledge learning rely on personal experience and long-term, resource-intensive theoretical skills training, respectively, resulting in high technical barriers and training costs for the welding industry.

[0003] To address these challenges, a range of computer-based welding query systems have emerged on the market. However, most of these systems utilize traditional development frameworks and programming languages, resulting in less than user-friendly interfaces and a poor user experience. They also struggle to seamlessly integrate with modern cloud computing and big data technologies. Furthermore, due to the wide variety of welding equipment and the lack of standardized communication protocols, traditional systems struggle to achieve effective data exchange and centralized control across multiple devices.

[0004] To this end, the present invention provides a welding inquiry system host computer based on a .NET framework. Summary of the Invention

[0010] As a further preferred technical solution of the present invention, the parameter update thread runs in real time, and the application is provided with an interface window corresponding to the parameter update thread and requiring identity authentication. The user needs to leave corresponding information in the server by registering in advance before being able to pass the identity authentication and use the function of the parameter update thread. The parameter update thread allows the user to pass the corresponding welding parameters and submit a request to the cloud server to insert or modify the welding parameters.

[0011] As a further preferred technical solution of the present invention, the function of the local query function thread is realized through the embedded database in the host computer, and some welding parameters are stored in the local embedded database in the host computer in the form of files.

The specific structure can be described with reference to the drawings of the patent application.

[0025] The present invention provides a welding inquiry system host computer based on the .NET framework, please refer to Figures 1 to 4 As shown, the host computer is an electronic device including a memory, a processor and a computer program stored in the memory and capable of running on the processor. The host computer is also the computer end of the welding inquiry system. It is characterized in that the host computer is based on the .NET Framework framework and uses C# language program to write and develop an application for the welding inquiry system. The application uses WinForms and WPF technologies in the .NET Framework framework to build the Windows user interface of the application. The host computer is embedded with a local database. The application is provided with several threads, and different threads are independent of each other and realize the transmission of data functions through events.

[0026] It should be noted that C# is a modern, general-purpose object-oriented programming language developed by Microsoft. It combines the efficiency of C / C++ with the ease of use of Java. It is a type-safe and high-performance programming language that supports multiple programming paradigms such as object-oriented programming, event-driven programming, and generic programming. It is widely used in Windows application development, server-side development, and other fields. The .NET Framework is an application development framework developed by Microsoft that supports multiple programming languages ​​such as C#, VB.NET, and F# for building and running applications on Windows. The framework includes a large number of class libraries, covering a wide range of functions from basic data structures and algorithms to advanced networking, security, and database access. The .NET framework-based welding inquiry system host computer of the present invention is based on the .NET Framework framework and uses C# language programming to develop an application program for the welding inquiry system, ensuring that the application program is stable and reliable and can be effectively integrated with existing industrial equipment and systems.

[0027] The application uses the HTTP protocol to communicate with the cloud server based on the big data model. The host computer uses the HTTP protocol to exchange data with the cloud server through the application. HTTP is a protocol for transmitting hypertext data on computer networks. It is one of the foundations of modern Internet communications and is used for communication between the client (this application) and the server. The message sent by the client is called a request, and the response message sent by the server is called a response. The client sends a request message to the server. The request message includes the request method, URL, protocol version, request header and request data. The server responds with a status line. The content of the response includes the protocol version, success or error code, server information, response header and response data.

[0028] The application uses Socket connection to communicate with the centralized controller, and the host computer uses Socket connection to exchange data with the centralized controller through the application. Socket provides a communication mechanism in network programming, which enables programs on different computers to exchange data and communicate through the network. Socket is an abstract layer between the application layer and the transport layer, which can be implemented based on different communication protocols. The most common ones are based on TCP (Transmission Control Protocol) or UDP (User Datagram Protocol), which is used to realize communication between processes in the network. It allows clients and servers to send and receive data through the network, realizing data interaction between remote computers.

[0029] The application uses SQLite for local storage of database data. SQLite is a lightweight database management system that is widely used worldwide. It provides a lightweight, fast and reliable database solution that is particularly suitable for applications that do not need to run on traditional client-server architectures. It reduces the maintenance and operational complexity of the database, allowing developers to focus more on the development of the application itself rather than database maintenance and optimization. The SQLite database is completely self-sufficient, highly reliable, simple to configure, and does not require reliance on complex settings or external servers.

[0030] The application uses the open source graphics library oxyplot to visualize data. The graphics library oxyplot includes a variety of icons such as line charts, bar charts, scatter plots, pie charts, heat maps, etc., and can be applied to applications developed with the .NET Framwork framework to visualize the corresponding welding parameters and the current and voltage waveforms collected in real time during the welding process to program users.

[0031] The WinForms technology provides predefined controls including buttons, text boxes, and list boxes for building the Windows user interface of an application. Developers can quickly build and design traditional Windows user interfaces by dragging and dropping controls and writing event handlers. Although it is relatively simple in terms of visual and dynamic effects, it provides rapid development and good scalability, and is one of the development tools chosen by many developers for designing industrial host computers.

[0032] WPF technology provides decoupled design support and a data binding mechanism for building an application's Windows user interface. WPF is a modern user interface technology developed by Microsoft for creating rich, interactive Windows desktop applications. WPF utilizes a vector-based graphics rendering engine that enables high-quality graphics display. It provides a decoupled design for building an application's Windows user interface, allowing designers and developers to effectively collaborate on interface design and development. Furthermore, WPF technology provides a data binding mechanism for building an application's Windows user interface. This mechanism uses the MVVM model to easily bind user interface elements and data sources, making it easier for developers to implement data-driven applications.

[0033] The application is provided with an intelligent query function thread, a parameter update thread, a local query function thread and a parameter synchronization thread.

[0034] The intelligent query function thread sets up an interface window through the application, and inputs text into the interface window to pass the parameter conditions to be queried to the application, and clicks the query button in the interface window to trigger the query event of the application. The application sends a query request to the cloud server through the HTTP protocol. The cloud server responds according to the input text and the query parameter conditions, and exchanges the response content to the application of the upper computer. The application of the upper computer extracts and modifies the response content and displays it through the interface window; if the query conditions are matched in the large database of the cloud server, the corresponding welding parameters will be returned at the same time as the response to the application. The application extracts and sorts the welding parameters and sends them to the parameter synchronization thread through an event.

[0035] The parameter update thread runs in real time. The application is provided with an interface window corresponding to the parameter update thread and requiring identity authentication. The user needs to leave corresponding information in the server through registration in advance before being able to pass the identity authentication and use the function of the parameter update thread. The parameter update thread allows the user to pass the corresponding welding parameters and submit a request to the cloud server to insert or modify the welding parameters. The cloud server will provide real-time feedback on the request and inform the user of the request result through the interactive interface. The same applies to the account management function.

[0036] The function of the local query function thread is realized through the embedded database in the host computer. Some welding parameters are stored in the local embedded database in the host computer in the form of files. The user completes the query in the local embedded database based on the welding conditions, and the query results are displayed to the user. The welding parameters obtained by the query are sent to the parameter synchronization thread through events.

[0037] The parameter synchronization thread receives the complete welding parameters sent from the intelligent query function thread and the local query function thread. The user can modify some welding parameters, and the modified parameters can be sent to the centralized controller via the network; The centralized controller will also periodically send back the data collected during the welding process through the network. The data collected by the centralized controller will be analyzed and processed and then visualized in the drawing control.

[0038] The centralized controller is based on the RK3568 high-performance CPU for personalized onboard design, and software development is carried out based on this hardware platform. The industrial control software of the centralized controller is designed and developed based on Linux QT5 to realize data interaction with mobile terminals and computer terminals. At the same time, it completes data collection, processing, storage, upload, status monitoring and control of multiple devices based on the field bus. The centralized controller has onboard Bluetooth, optical fiber network, WIFI and other interfaces, supporting multiple modes of wireless communication. The interface diagram is as follows Figure 2 As shown; like Figure 3 As shown, a network Socket connection is established between the central controller and the mobile terminal and the computer terminal through the TCPIP protocol. The central controller receives instructions and data from the mobile terminal and the computer terminal, and after completing the instruction matching and analysis, sends the data to the corresponding welding machine equipment through the field bus to realize non-contact wireless control of the welding machine. At the same time, the central controller receives data from each welding machine equipment through the field bus, analyzes it and uploads it synchronously to the mobile terminal and the computer terminal, including basic welding parameter data such as current, voltage, wire feeding speed during the welding process, as well as the working mode and working status of the welding equipment.

[0039] It should be noted that: with the help of the centralized controller, users can realize dynamic monitoring of the status of on-site equipment, complete the collection and recording of real-time data of the equipment in the form of log files, which is convenient for subsequent review and backtracking, and the network connection method improves the flexibility of equipment connection, and users can realize remote equipment monitoring and control. In actual working scenarios, users can connect to the centralized controller through mobile or computer terminals, and complete non-contact parameter adjustment and status monitoring of welding equipment with the help of remote control, without the need for additional space movement to operate the actual equipment, thereby improving the flexibility and convenience of the working space.

[0040] Combine Figure 4 As shown, the technical solution of the mobile terminal is as follows: The mobile terminal uses an APP developed based on the Android operating system, which is compatible with mobile phone or tablet applications. The APP is provided with a voice recognition API. The APP converts the user's voice input into text input based on iFlytek's voice technology through the API. The text input submits data to the server through a post request, and queries the database stored in the server through the HTTP protocol. The parameters returned by the server after querying the total database are parsed and displayed by the APP to guide the user to perform welding operations; The APP also exchanges data with the centralized controller through socket connection and TCP / IP protocol, sending the user-set parameters to the centralized controller and receiving the welding equipment data returned by the centralized controller.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
