Description

Technical Field

[0001] This application relates to the field of laser technology, and in particular to a method for modifying parameters of a laser welding machine system. This application also relates to a device for modifying parameters of a laser welding machine system, a computing device, and a computer-readable storage medium. Background Technology

[0002] To facilitate product production and management, the hardware configuration of each laser welding machine is consistent. However, to address different usage environments and processes, different adaptability parameters are introduced before shipment. In actual use, customers may need to adjust the equipment's functions. However, as these adaptability parameters are trade secrets of each laser welding machine manufacturer, they cannot be directly provided to customers.

[0003] Specifically, adaptability parameters are a collective term for a set of internal parameter settings of a laser welding machine system. These parameters are modified by inputting configuration commands through the external interface of the laser welding machine. Since these configuration commands are applicable to all laser welding machines of the same model, directly disclosing them to non-company personnel could lead to malicious misuse and illegal application to other machines of the same model, damaging the product's value. Furthermore, configuration commands often contain commercial parameters of the product; disclosing them directly to non-company personnel could leak trade secrets, damaging the company's value. Additionally, because configuration commands themselves lack timeliness—they can be entered at any time to modify the equipment's adaptability parameters—disclosing them to non-company personnel could result in repeated misuse, further damaging the product's value.

[0047] Many specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed below.

[0048] The terminology used in one or more embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the scope of one or more embodiments of this application. The singular forms “a,” “the,” and “the” used in one or more embodiments of this application and in the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” used in one or more embodiments of this application refers to and includes any or all possible combinations of one or more associated listed items.

[0049] It should be understood that although the terms first, second, etc., may be used to describe various information in one or more embodiments of this application, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first may also be referred to as second without departing from the scope of one or more embodiments of this application, and similarly, second may also be referred to as first.

[0050] First, the terminology used in one or more embodiments of the present invention will be explained.

[0051] 3DES: Triple Data Encryption Standard, is a symmetric encryption algorithm. It is an enhanced version of DES, the data encryption standard, but the encryption algorithm requires that the encrypted information can only be a multiple of 8 bytes.

[0052] SN Number: Each laser welding machine has a unique SN number, which serves as the unique identifier for the equipment.

[0053] This application provides a method for modifying parameters of a laser welding machine system. This application also relates to a device for modifying parameters of a laser welding machine system, a computing device, and a computer-readable storage medium, which will be described in detail in the following embodiments.

[0054] Figure 1 A flowchart illustrating a method for modifying parameters of a laser welding machine system according to an embodiment of this application is shown, specifically including the following steps:

[0055] Step S102: Collect the user change request and the first device code input by the target user, and retrieve the instruction time information;

[0056] Step S104: Generate an original configuration instruction based on the user's change request, and combine the instruction time information with the first device encoding to generate an encrypted configuration instruction;

[0057] Step S106: Use the second device code of the target welding machine as the decryption key to determine whether the encrypted configuration instruction can be decrypted. If yes, modify the parameters of the target welding machine by using the decrypted instruction time information and the original configuration instruction. If no, stop modifying the parameters of the target welding machine and report a stop message.

[0058] The adaptability parameters include settings for the upper limit of laser welding machine power, the operating temperature range of laser welding machine, the cooling system parameters of laser welding machine, the communication interface parameters of laser welding machine, the fault monitoring point settings of laser welding machine, the log parameters of laser welding machine, the control system settings of laser welding machine, and the language settings of laser welding machine. These system adaptability parameters can be modified by inputting configuration commands through the external interface of the laser welding machine.

[0059] Based on this, for laser welding machines that require adaptive parameter modifications, the user inputs their own needs (i.e., user change requirements) and the device code of the laser welding machine requiring adaptive modifications (i.e., the first device code) to the encryption execution entity responsible for generating encryption configuration instructions. It should be noted that the encryption execution entity can be a host computer, an app, embedded software, a web front-end, or a network back-end, etc. The specific encryption execution entity is determined by the actual usage scenario, and this embodiment does not impose any limitations.

[0060] Next, the start time for generating the encrypted configuration instruction is determined, corresponding to the instruction time information. The encryption execution entity generates the original configuration instruction based on the user's change request instruction, and then, combined with the first device code and instruction time information, generates the encrypted configuration instruction. The encryption execution entity sends out the encrypted configuration instruction and decrypts it using the second device code of the target welding machine.

[0061] Specifically, the target welding machine is the welding machine currently undergoing adaptive parameter modification. There may be a situation where it is different from the welding machine corresponding to the first device number of the user-input encryption execution subject. In this case, it is impossible to successfully decrypt the encrypted configuration command through the second device number. This avoids the situation where the configuration command is maliciously used and illegally applied to other devices of the same model.

[0062] Furthermore, in step S104, the process of generating the original configuration instructions based on the user's change requirements is specifically implemented as follows in this embodiment:

[0063] Based on the user's changed requirements, the original configuration instructions, including packet header, instructions, data length, data, and packet footer, are generated.

[0064] Furthermore, in the above steps, the packet header and the packet footer consist of strings of a fixed format.

[0065] Furthermore, in step S104, the process of generating an encrypted configuration instruction by combining the instruction time information and the first device code is specifically implemented as follows in this embodiment:

[0066] Write the instruction time information into the specified position of the original configuration instruction to obtain a valid configuration instruction; use the first device code as the encryption key, and generate the encrypted configuration instruction based on the valid configuration instruction.

[0067] Furthermore, in the above steps, the process of using the first device code as the encryption key and generating encrypted configuration instructions based on valid configuration instructions is specifically implemented as follows in this embodiment:

[0068] Based on preset instruction completion rules, the valid configuration instructions are completed to obtain the final configuration instructions; the first device code is used as the encryption key, and the final configuration instructions are processed by a preset encryption algorithm to obtain the encrypted configuration instructions.

[0069] The configuration command consists of a string with a specific format, featuring uniform header and footer characters. Therefore, the original configuration command comprises five parts: header, command, data length, data, and footer. The command, data length, and data can vary depending on the specific requirements, resulting in inconsistent character lengths based on the configuration content. Because command completion is involved, to avoid confusion between the header / footer and the completion characters, the header and footer characters are set differently from the completion characters. For example, if completion is achieved using 0xAA, then the header and footer characters will not be 0xAA.

[0070] Based on this, the encrypted execution entity combines the instruction time information with the original configuration instruction. To facilitate data processing and post-decryption data analysis, the instruction time information is written to a designated location in the original configuration instruction, such as automatically appending the instruction time information to the original configuration instruction and integrating it into a valid configuration instruction. It should be noted that the instruction time information has a fixed format, such as being represented in YMDhms (year, month, day, hour, minute, second) format, where the value of seconds ranges from 0 to 60.

[0071] Next, the valid configuration instructions are encrypted. During the process of generating encrypted configuration instructions, the choice of encryption algorithm is determined by the actual use scenario. For some types of encryption algorithms, such as 3DES, there are requirements on the length of the data to be encrypted. Therefore, for such encryption algorithms, the valid configuration instructions are completed by the instruction completion rules associated with the encryption algorithm to obtain the final configuration instructions.

[0072] For example, such as Figure 2 A schematic diagram of the encrypted configuration command generation method for modifying parameters of a laser welding machine system is provided, wherein... Figure 2 (a) Characterizes the original configuration instruction, which specifies that the packet header is fixed at 0x3C and the packet tail is fixed at 0xC3; Figure 2 (b) A valid configuration instruction is characterized in which instruction timing information is written to the end of the original configuration instruction; Figure 2 (c) Representing the final configuration instruction. Since 3DES is used for encryption, and the encryption algorithm requires that the encrypted information must be a multiple of 8 bytes, but the valid configuration instruction is not necessarily a multiple of 8 bytes, it is not possible to directly use 3DES to encrypt the configuration instruction. Therefore, the encryption execution body will determine whether the length of the valid instruction is a multiple of 8. If it is not a multiple of 8, it will automatically pad the valid instruction with 0xAA to make the instruction length a multiple of 8, thus obtaining the final configuration instruction.

[0073] It should be noted that the first and second device codes serve to identify the corresponding welding machine. Therefore, the device serial number (SN) can be used as the device code. Following the example above, in the 3DES encryption process, the m-byte final configuration instruction is encrypted with the 16-byte device SN to obtain an m-byte encrypted configuration instruction. This method establishes a strong correlation between the device identity and the encrypted configuration instruction, preventing the configuration instruction from being misused on other devices of the same model, and also preventing the leakage of trade secrets.

[0074] So, the generation process of the encryption configuration instructions in the example above is as follows: Figure 3 The provided method for modifying parameters of a laser welding machine system includes an encrypted configuration instruction generation logic diagram. The overall process involves generating an original configuration instruction based on the user's modification requirements, integrating the original configuration instruction with the current time (the current time being the instruction time information), and then determining whether the length of the valid configuration instruction is a multiple of 8. If not, "0xAA" is appended to the end of the valid configuration instruction to generate the final configuration instruction. If the length of the valid configuration instruction is a multiple of 8, it is directly used as the final configuration instruction and participates in the encryption process using the laser welding machine's serial number (SN) as the key, ultimately generating the encrypted configuration instruction.

[0075] Furthermore, in step S106, the process of modifying the parameters of the target welding machine by using the decrypted instruction timing information and the original configuration instruction is specifically implemented as follows in this embodiment:

[0076] The second device code is used as the decryption key to decrypt the encrypted configuration instruction to obtain the final configuration instruction; irrelevant bytes are removed from the final configuration instruction to obtain the valid configuration instruction; based on the valid configuration instruction, the instruction time information and the original configuration instruction are determined, and the parameters of the target welding machine are modified.

[0077] Furthermore, in the above steps, the process of determining the instruction time information and the original configuration instruction based on the valid configuration instruction is specifically implemented as follows in this embodiment:

[0078] Based on the time format corresponding to the instruction time information, the instruction time information is extracted from the specified position of the valid configuration instruction, and the original configuration instruction is determined; the current time information is called and compared with the instruction time information to determine whether the time difference is less than a preset time threshold. If so, the parameters of the target welding machine are modified according to the original configuration instruction; if not, the parameter modification of the target welding machine is stopped, and a stop information is reported.

[0079] The decryption execution entity can be an app, host computer, embedded software, web front-end, network back-end, etc. The encryption execution entity and the decryption execution entity can be the same entity or different entities. Generally, the encryption execution entity and the decryption execution entity are different entities, such as the encryption execution entity being the host computer and the decryption execution entity being the corresponding app.

[0080] In addition, the decryption execution entity is connected to the target welding machine. The connection method can be wired or wireless. Wired connection includes network cable, USB, serial port, CAN port, etc., while wireless connection includes Bluetooth, Wi-Fi, 4G, 5G, Zigbee, satellite communication, etc.

[0081] Based on this, the decryption execution entity sends a query command to read the second device code of the target welding machine. The execution entity uses the second device code as the decryption key to decrypt the encrypted configuration command, obtaining the decrypted final configuration command. For the final configuration command that completes the valid configuration command using preset command completion rules, the characters used for completion are removed. These characters used for completion are irrelevant and do not affect the original configuration command or command time information in the final configuration command.

[0082] For example, such as Figure 4The provided method for modifying parameters of a laser welding machine system is illustrated in the diagram of the encrypted configuration instruction splitting. For a valid configuration instruction, the instruction time information can be separated from the specified position of the valid configuration instruction according to the time format corresponding to the instruction time information, thereby determining the original configuration instruction.

[0083] For the decryption process of encrypted configuration commands, such as Figure 5 The provided method for modifying parameters of a laser welding machine system includes an encrypted configuration instruction breakdown logic diagram. The user receives the encrypted instruction, i.e., the encrypted configuration instruction, and inputs it into the accompanying app, which is the decryption execution entity. The app uses the serial number (SN) of the laser welding machine as the key for decryption. Here, the laser welding machine is the target welding machine, and its SN is the second device code. Then, it checks if the decrypted data ends with "0xAA". If so, the extra "0xAA" is removed; otherwise, a valid decrypted instruction, i.e., a valid configuration instruction, is generated.

[0084] In the process of decryption execution, the final configuration instruction is processed by removing all 0xAA bytes at the end to obtain the decrypted valid instruction. Since the last bit of the time information is seconds and its value ranges from 0 to 60, it cannot be 0xAA. Therefore, when the last byte is not 0xAA, it indicates that the supplementary bytes have been removed.

[0085] The valid decryption commands are then divided into original command information and command time information. Here, the valid decryption commands are valid configuration commands, and the original command information is the original configuration command. Specifically, the command time information is selected from a specified location according to the time format corresponding to the command time information, leaving the remaining initial part of the original configuration command. If the time threshold is preset to one hour, the command time information is compared with the current time to see if it is within one hour. If not, the command is discarded; if so, the command is sent to the laser welding machine. The laser welding machine, in this case, is the target welding machine, and executing the corresponding command means modifying the parameters according to the original configuration command.

[0086] In summary, encrypting configuration commands prevents the leakage of product information and trade secrets; using a specified device serial number as the encryption key prevents commands from being misused on other devices, thus protecting the product's commercial value; adding command time information to the configuration information prevents commands from being repeatedly used after timeout, further protecting the product's commercial value; and adding specific bytes after the command solves the problem that 3DES must encrypt and decrypt data that is a multiple of 8.

[0087] Corresponding to the above method embodiments, this application also provides an embodiment of a laser welding machine system parameter modification device. Figure 6A schematic diagram of a laser welding machine system parameter modification device according to an embodiment of this application is shown. Figure 6 As shown, the device includes:

[0090] The parameter modification module 606 is configured to use the second device code of the target welding machine as the decryption key to determine whether the encrypted configuration instruction can be decrypted. If so, the parameters of the target welding machine are modified by using the decrypted instruction time information and the original configuration instruction. If not, the parameter modification of the target welding machine is stopped and a stop information is reported.

[0099] In an optional embodiment, the parameter modification module 606 is further configured to:

If so, the parameters of the target welding machine are modified according to the original configuration instruction; if not, the parameter modification of the target welding machine is stopped, and a stop information is reported.

[0101] In an optional embodiment, the encryption module 604 is further configured to:

[0102] The packet header and the packet footer consist of strings of a fixed format.

This method incorporates configuration instructions into instruction time information and uses a specified device code as a key for encryption, effectively solving the industry problem of remotely adjusting the adaptability parameters of laser welding machines while preventing the leakage and misuse of these parameters.
