Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to a welding power supply channel copying system and method. Background Technology

[0002] A channel typically refers to a complete set of welding parameters stored within a welding power source, such as current, voltage, wire feed speed, pulse parameters, waveform control, and dynamic response. Channel copying usually refers to completely replicating all welding parameters and settings from one welding power source to another. On a production line, channel copying is necessary when configuring the same welding parameters for a large number of welding power sources, or when configuring the same welding parameters for welding power sources at different workstations.

[0003] In existing technologies, channel copying methods use USB flash drive copying, which involves exporting data from the master machine via USB flash drive and then inserting the USB flash drive into the slave machine to import the data. However, this method is cumbersome, inefficient, and difficult to adapt to large-scale equipment deployments.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a welding power supply channel copying system and method, which transmits channel data uploaded by the master machine to the corresponding slave machine through a cloud management system, thereby simplifying the operation, improving the efficiency of welding power supply channel data copying, and enabling large-scale deployment.

[0006] To achieve the above objectives / to solve the above technical problems, this application adopts the following technical solution:

[0007] In a first aspect, this application provides a welding power supply channel copying system, comprising:

[0008] The cloud management system and multiple welding power sources are connected through a communication network. The welding power sources are connected to the cloud management system via IoT modules to realize the transmission of channel data between the welding power sources and the cloud management system.

[0009] Multiple welding power sources include a master unit and at least one slave unit. The master unit uploads channel data to the cloud management system through its IoT module, and the cloud management system transmits the channel data to the slave unit.

[0010] The channel data includes the welding parameters of the welding power source.

[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: the master unit uploads channel data to the cloud management system via the IoT module, and the cloud management system transmits the channel data to the slave units, realizing automated operation of welding power supply channel data copying, efficient transmission, and large-scale deployment capabilities. Specifically, the welding power supply integrates an IoT module, which establishes a communication network connection between the welding power supply and the cloud management system. The IoT module can upload the welding power supply's channel data to the cloud management system and also write the channel data sent by the cloud management system into the welding power supply. Multiple welding power supplies are deployed at different workstations. One welding power supply is selected as the master unit, and the others are used as slave units. The user sets the welding parameters on the master unit and stores them in the form of channel data. Then, the master unit's IoT module reads the channel data and uploads it to the cloud management system via the communication network. The cloud management system transmits the channel data to the slave units, and the slave units receive the channel data through the IoT module and write it into their storage. Network transmission between the cloud management system and IoT module eliminates the need for manual operation, significantly reducing operational complexity. The cloud management system can simultaneously transmit channel data to multiple slave devices, enabling batch copying and shortening configuration time. Furthermore, the cloud management system can store and manage channel data, achieving real-time updates and maintenance of the channel data.

[0012] Furthermore, the master unit and the slave unit respectively send the master unit model information and the slave unit model information to the cloud management system; the cloud management system receives the master unit model information and the slave unit model information, and determines whether the master unit model information and the slave unit model information are the same. If they are the same, the channel data sent by the corresponding master unit is sent to the corresponding slave unit.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: the master unit and the slave unit send model information to the cloud management system, and the cloud management system makes a consistency judgment. The channel data is transmitted only when the models of the master unit and the slave unit are the same, which ensures the compatibility of the parameters of the master unit and the slave unit and avoids the problem of parameter mismatch caused by different models.

[0014] Furthermore, the IOT module includes: a communication interface unit for reading channel data from the storage unit of the welding power supply and / or writing channel data to the storage unit via the central controller of the welding power supply.

[0015] Furthermore, the communication interface unit transmits channel data with the central controller via the UART communication protocol or the CAN communication protocol.

[0016] Furthermore, the IoT module includes a communication unit for wireless transmission with the cloud management system.

[0017] Furthermore, the communication unit is specifically a 4G or 5G communication unit.

[0018] Secondly, this application also provides a method for copying welding power supply channels, applicable to the welding power supply channel copying system of any of the foregoing claims, the copying method comprising:

[0019] The cloud management system receives channel data and host machine model information sent by the host machine;

[0020] Receive sub-unit model information sent by the sub-unit;

[0021] Determine whether the slave unit model information is the same as the master unit model information;

[0022] If the slave unit model information is the same as the master unit model information, the channel data will be sent to the slave unit.

[0023] Furthermore, when the slave unit model information is the same as the master unit model information, sending channel data to the slave unit also includes:

[0024] If the slave unit model information is the same as the master unit model information, determine whether the channel data needs to be fine-tuned based on the slave unit model information;

[0025] When fine-tuning of channel data is required, fine-tuning operations are performed on the channel data to obtain fine-tuned channel data;

[0026] Send the fine-tuning channel data to the slave device; and / or

[0027] The channel data is sent to the slave unit without requiring any fine-tuning of the channel data.

[0028] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the cloud management system determines whether the channel data needs to be fine-tuned, and if fine-tuning is required, it performs fine-tuning to obtain fine-tuned channel data adapted to the slave device, thus solving the compatibility problem caused by individual differences in devices of the same model.

[0029] Compared with the prior art, the beneficial effects achieved by this application are as follows:

[0030] 1. The master unit uploads channel data to the cloud management system via the IoT module. The cloud management system then transmits the channel data to the slave unit, thus automating the copying of welding power channel data, enabling efficient transmission and large-scale deployment.

[0031] 2. The master unit and the slave unit send model information to the cloud management system, and the cloud management system performs consistency judgment. Only when the model of the master unit and the slave unit is the same, the channel data is transmitted, which ensures that the parameters of the master unit and the slave unit are compatible and avoids the problem of parameter mismatch caused by different models.

[0032] 3. The cloud management system determines whether fine-tuning of the channel data is required. If fine-tuning is required, the system performs the fine-tuning operation to obtain fine-tuned channel data adapted to the slave device, thus solving the compatibility problem caused by individual differences in devices of the same model.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0039] Example 1:

[0040] like Figure 1 As shown, Figure 1 This is a system diagram of a welding power supply channel copying system provided in Embodiment 1 of the present invention; as shown in the system diagram, the welding power supply channel copying system includes:

[0041] The cloud management system and multiple welding power sources are connected via a communication network. The welding power sources are connected to the cloud management system via IoT modules to realize the transmission of channel data between the welding power sources and the cloud management system. The multiple welding power sources include a master unit and at least one slave unit. The master unit uploads the channel data to the cloud management system through its IoT module, and the cloud management system transmits the channel data to the slave unit.

[0042] Specifically, the welding power supply includes a storage unit and a central controller (hereinafter referred to as CPU). The storage unit is used to store channel data, which includes multiple sets of welding parameters. Each set of welding parameters includes, but is not limited to, current, voltage, wire feed speed, and pulse frequency. The CPU is used to control the storage unit to write, adjust, and recall channel data.

[0043] Specifically, the welding power supply integrates an IoT module, which connects to the cloud management system via a communication network and transmits or receives information to or from the cloud management system through the IoT module.

[0044] Specifically, users can select one welding power source from multiple welding power sources as the master unit. The user inputs multiple sets of welding parameters as channel data on the master unit, which is then stored in the master unit's storage unit. The remaining welding power sources act as slave units, receiving channel data sent by the cloud management system and writing it into their storage units.

[0045] Specifically, the cloud management system includes a cloud server and a terminal. The channel data sent by the master machine is stored in the cloud server. Users can control the cloud server to adjust and delete channel data from the terminal, and can also control the cloud server to send channel data to the slave machine.

[0046] Furthermore, the IOT module includes a communication interface unit for reading channel data from the storage unit and / or writing channel data to the storage unit via the central controller of the welding power supply; the communication interface unit and the central controller transmit channel data via the UART communication protocol or the CAN communication protocol.

[0047] like Figure 2 As shown, Figure 2 The system diagram shows the communication between the welding power supply and the IOT module via the UART communication protocol. The data commands based on the UART communication protocol are shown in Table 1 below.

[0050] like Figure 3 As shown, Figure 3The system diagram shows the communication between the welding power supply and the IOT module via the CAN communication protocol. The data commands based on the CAN communication protocol are shown in Table 2 below.

[0051]

[0052] Table 2

[0053] Furthermore, the IoT module includes a communication unit for wireless transmission with the cloud management system; specifically, the communication unit is a 4G or 5G communication unit.

[0054] Furthermore, the master unit and the slave unit respectively send the master unit model information and the slave unit model information to the cloud management system; the cloud management system receives the master unit model information and the slave unit model information, and determines whether the master unit model information and the slave unit model information are the same. If they are the same, the channel data sent by the corresponding master unit is sent to the corresponding slave unit.

[0055] Specifically, model information includes, but is not limited to, manufacturer code, device model, and firmware version number.

[0056] Example 2:

[0057] This embodiment provides a method for copying welding power supply channels, applicable to the welding power supply channel copying system as described in Embodiment 1.

[0058] like Figure 4 As shown, Figure 4 This is a general flowchart of a welding power supply channel copying method provided in Embodiment 2 of this application. This flowchart only illustrates the logical sequence of the method described in this embodiment. Without conflict, in other possible embodiments of the present invention, different methods may be used. Figure 4 The steps shown or described are performed in the order indicated. Copying methods include:

[0059] S100: The cloud management system receives channel data and host machine model information sent by the host machine;

[0060] Specifically, the host machine uses the IoT module to read the pre-stored channel data and host machine model information in its storage unit, and then uploads it to the cloud management system via the communication unit. The cloud management system stores the received channel data and host machine model information in the cloud server.

[0061] S200: Receives sub-unit model information sent by the sub-unit;

[0062] Specifically, when the slave device starts up for the first time or when the user issues a command to copy channel data, it sends a copy request to the cloud management system through its corresponding IoT module. This copy request includes the slave device model information. The cloud management system then stores the slave device model information on the cloud server.

[0063] S300: Determine whether the slave unit model information is the same as the master unit model information;

[0064] Specifically, the cloud server retrieves the sub-machine model information and the parent machine model information; compares whether the manufacturer code and device model are completely consistent and whether the firmware version number is compatible; if they are the same, they are determined to be different otherwise.

[0065] S400: When the slave unit model information is the same as the master unit model information, the channel data is transmitted to the slave unit.

[0066] Specifically, when the S300 determines that they are the same, the cloud management system performs the following operations: retrieves the channel data of the same master machine based on the slave machine; transmits the channel data to the slave machine; after receiving the channel data, the slave machine's IoT module writes the channel data into the slave machine's storage unit.

[0067] Specifically, when the S300 determines that they are different, the cloud management system terminates the operation.

[0068] Furthermore, S400 includes: when the slave unit model information is the same as the master unit model information, determining whether fine-tuning of the channel data is required based on the slave unit model information;

[0069] For example, users can set corresponding fine-tuning parameters based on the actual working conditions of each slave unit. For instance, when a slave unit is welding, the current usually needs to be 3% to 5% higher than the standard value to achieve the same effect as the master unit. Users can set the fine-tuning parameters of each slave unit through the slave unit or the terminal of the cloud management system. The fine-tuning parameters of each slave unit are stored on the cloud server and form a fine-tuning library.

[0070] Specifically, when the slave unit model information is the same as the master unit model information, the cloud server calls the slave unit model information and searches the fine-tuning library for corresponding fine-tuning parameters based on the slave unit signal information. If the corresponding fine-tuning parameters exist, it is determined that fine-tuning of the channel data is required; otherwise, it is determined that fine-tuning of the channel data is not required.

[0071] When fine-tuning of channel data is required, fine-tuning operations are performed on the channel data to obtain fine-tuned channel data;

[0072] Specifically, when the cloud server needs to fine-tune the channel data, it performs fine-tuning operations on the channel data to obtain fine-tuned channel data: it obtains fine-tuning parameters from the fine-tuning library, and recalculates the channel data based on the fine-tuning parameters to obtain fine-tuned channel data.

[0073] Transmit the fine-tuning channel data to the slave device; and / or

[0074] The channel data is transmitted to the slave device without requiring fine-tuning of the channel data.

[0075] It should be noted that the cloud management system uses the IoT module to copy the channel data of the welding power supply master unit and transmits the channel data to the cloud management system for storage; the cloud management system can also perform fine-tuning of the channel data and transmit it to the slave unit.

[0076] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0077] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
