Description

Technical Field

[0001] The present application relates to the field of laser technology, and in particular to a method, device, computing device, and storage medium for upgrading the firmware of a laser welding machine system. Background Art

[0002] A laser welding system typically consists of a main system and multiple subsystems. The main system is generally the laser control system, while the subsystems typically include the human-machine interface (HMI) system, cooling system, and welding gun control system. The main system is responsible for turning the laser on and off and communicating data with the outside world. The HMI system handles control and feedback related to human operation, such as the display screen, digital tube, LED lights, buttons, and knobs. The cooling system is responsible for maintaining a suitable operating temperature inside the equipment. The welding gun control system is responsible for controlling the laser's oscillation during laser welding. Each system is controlled by an independent chip, and each control chip requires one or more appropriate firmware segments to meet the required functional requirements of the equipment.

[0003] Since the working environment of laser welding machines is relatively harsh, with large electromagnetic interference and metal debris, in order to protect the laser welding machine system and reduce the contact points between the internal system and the external environment, generally only the main system has a physical interface (wired or wireless) for communication with the outside world, and the subsystem communicates with the main system inside the device through wired means.

[0004] In order to enable wired or wireless upgrades, there are generally two segments of firmware inside the chip. The first segment is the boot firmware (Bootloader for short), which is responsible for docking the upgrade interface of the device, and the second segment is the functional firmware, which is responsible for realizing the operation functions of the device. Upgrading generally refers to the process of receiving new functional firmware transmitted from the outside while the boot firmware is running, and then overwriting the original functional firmware. Firmware is generally written by software engineers according to the functional requirements of the device through software development, and a bin file is generated after compilation. The bin file is a binary code that is directly run by the system chip, so it is impossible to directly add verification information or identification information to the bin file. However, when using remote upgrades, there is a certain risk of upgrading the wrong firmware, which will cause the device to operate abnormally. In severe cases, it may cause the device to become "bricked" and unable to start and use. Summary of the Invention

[0055] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the scope of the present application. Therefore, the present application is not limited to the specific implementations disclosed below.

[0056] The terms used in one or more embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit one or more embodiments of the present application. The singular forms "a", "the" and "the" used in one or more embodiments of the present application and the appended claims are also intended to include 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 the present application refers to and includes any or all possible combinations of one or more associated listed items.

[0057] It should be understood that although the terms "first," "second," and the like may be used to describe various information in one or more embodiments of the present application, such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another. For example, "first" may also be referred to as "second," and similarly, "second" may also be referred to as "first," without departing from the scope of one or more embodiments of the present application.

[0058] This application provides a laser welder system firmware upgrade method, a laser welder system firmware upgrade device, a computing device, and a computer-readable storage medium, each of which is described in detail in the following embodiments.

[0059] Figure 1 A flowchart of a laser welding system firmware upgrade method provided in accordance with an embodiment of the present application is shown, which specifically includes the following steps:

[0060] Step S102: receiving an upgrade request through a main system of the laser welder, wherein the laser welder includes a main system and multiple subsystems, the main system is directly connected to the outside, and the subsystems are not connected to the outside;

[0061] Step S104: determining, according to the upgrade request, one of the main system and all the subsystems as a system to be upgraded;

[0062] Step S106: selecting a target writing mode according to the operating state of the system to be upgraded, and writing the upgrade file into the system to be upgraded according to the target writing mode;

[0063] Step S108: executing an upgrade error prevention process, wherein the upgrade error prevention process determines an upgrade result through the system code of the upgrade file.

[0064] Among them, such as Figure 2As shown in the system architecture diagram of a laser welding machine system firmware upgrade method provided, for a laser welding machine, there is a main system and multiple subsystems, and the main system and the subsystem each have a system code corresponding to themselves. The main system exchanges information with the external system, the subsystem does not exchange information with the external system, and the subsystems do not exchange information with each other. Each subsystem only exchanges information with the main system.

[0065] It should be noted that in the scenario of firmware upgrade for laser welding machines, the main system can be easily upgraded via wired or wireless means, while the subsystems within the product can often only be upgraded via a downloader before factory assembly. It is difficult to upgrade and maintain the subsystems after leaving the factory. In addition, it is difficult to determine the correctness of the bin files required for upgrading the firmware before the upgrade. When the wrong firmware is upgraded, the losses caused are often large and irreversible.

[0066] Based on this, the present application provides a method for upgrading the firmware of a laser welding machine system, wherein an upgrade request is received by a main system connected to an external system, and according to the upgrade request, the system that needs to undergo a firmware upgrade is determined to be the system to be upgraded, and the selection range of the system that needs to undergo a firmware upgrade is the main system and all subsystems. Then, according to the operating status of the system to be upgraded, the target writing method is determined, wherein the operating status represents the specific logical section in which the system to be upgraded runs in the internal flash, and different operating states represent different logical sections in which the system to be upgraded runs, and the target writing method represents the method in which the upgrade file is written to the system to be upgraded. Then, according to the target writing method, the upgrade file is written to the system to be upgraded, and the upgrade error prevention process is executed. In the upgrade error prevention process, the system code of the upgrade file is used to determine whether the upgrade of the system to be upgraded is successful.

[0067] Furthermore, before step S102, it is also included to determine whether there is a functional firmware missing fault. In this embodiment, the determination process is specifically implemented as follows:

[0068] Step S101: In response to the start-up of the laser welder, the main system and all the subsystems are running, wherein the internal flash of the main system and all the subsystems contains four logical segments arranged in sequence, namely the boot segment, the function segment, the feature identification segment 1 and the feature identification segment 2; for any one of the main system and all the subsystems, when the boot firmware stored in the boot segment is running, the system code of the system is written into its own feature identification segment 1, and the feature identification segment 1 and the feature identification segment 2 are compared. If they are the same, jump to the functional firmware stored in its own function segment. If they are different, report the comparison result.

[0069] Among them, such as Figure 3The internal flash memory schematic for a laser welding system firmware upgrade method is shown in the following figure. For laser welding machines, the main system and subsystems are controlled by independent chips. Each chip's internal flash memory consists of N pages, which are divided into four logical segments: the boot segment, the function segment, the signature segment 1, and the signature segment 2. The boot segment starts on page 1 of the internal flash memory and is a page long, storing the boot firmware. The function segment starts on page b of the internal flash memory and is cb page long, storing the function firmware. The signature segment 1 starts on the second-to-last page of the internal flash memory (i.e., page n-1) and is one page long, storing the system code for the boot segment. The signature segment 2 starts on the last page of the internal flash memory (i.e., page n) and is one page long, storing the system code for the function segment.

[0070] Based on this, Figure 4 As shown in the firmware missing fault detection flow chart of a laser welding machine system firmware upgrade method, the system enters the boot firmware after power-on / reset, that is, in response to the laser welding machine startup, the main system and all the subsystems run. For any of the systems, the system will first start running from the first page of the flash, that is, the boot firmware. At this time, the program will write the system code of this system in the flash feature identification segment 1, that is, Figure 4 1. Set the flash identification segment to system code X1, and then read the system code in the feature identification segment 2, that is, Figure 4 2. Read the content X2 of the flash identification segment 2; then determine whether the system code of the feature identification segment 2 is the same as the system code of the feature identification segment 1, that is, Figure 4 Is X1 equal to X2?

[0071] If the comparison results are the same, jump and run the functional firmware, i.e. Figure 4 The jump to the functional firmware in the program runs normally; if they are different, Figure 4 1. Continue to run the boot firmware, and 2. Report the missing function firmware fault, remind the user to upgrade the firmware and wait for the firmware upgrade.

[0072] Furthermore, in step S104, according to the upgrade request, the process of determining one of the main system and all subsystems as the system to be upgraded is specifically implemented as follows in this embodiment:

[0073] The system code to be upgraded contained in the upgrade request is queried; and according to the system code to be upgraded, one of the main system and all the subsystems is determined to be the system to be upgraded.

[0074] When the main system receives an external upgrade request, it first parses the upgrade request to obtain the system code for this upgrade, i.e., the system code to be upgraded, and then determines the system to be upgraded, i.e., the system to be upgraded, based on the system code to be upgraded.

[0075] It should be noted that if Figure 2 As shown in the system architecture diagram of a laser welding machine system firmware upgrade method provided, each system has a system code. The number of bits of the system code is determined by the actual application scenario. As long as it satisfies any non-repeating value and is different from the initial state, it can be used. Taking a 128-bit system code as an example, the system code range is 0≤system code<0xFFFFFFFF. Since the default value is all 1 when the flash is not programmed, that is, 0xFFFFFFFF, the system code must exclude 0xFFFFFFFF. Each bit can be 0 or 1. It can be calculated that the error probability caused by accidental repetition of the system code is 1 / 2 128 =2.94*10 -39 , greatly reducing the possibility of repeated errors.

[0076] Furthermore, after step S104, for the two different situations where the system to be upgraded is a main system or a subsystem, different processing is required. The specific processing process, in this embodiment, is specifically implemented as follows:

[0077] Step S105: When the system to be upgraded is the main system, the main system receives the upgrade file; when the system to be upgraded is the subsystem, the main system sends the received upgrade file to the system to be upgraded.

[0078] Among them, if the system code to be upgraded indicates the main system, the main system automatically performs the upgrade operation; if the system code to be upgraded indicates the subsystem, the main system notifies the corresponding subsystem after receiving the bin file, that is, the upgrade file, and guides the subsystem to complete the upgrade operation.

[0079] Furthermore, in step S106, a target writing mode is selected according to the operating state of the system to be upgraded, and the upgrade file is written into the system to be upgraded according to the target writing mode. In this embodiment, the specific implementation is as follows:

[0080] When the running status is running on the functional firmware, the system code in the feature identification segment 2 is erased, and the process jumps to the boot firmware. The upgrade file is received in the boot firmware, and the upgrade file is written into the functional segment. After the writing is completed, the process jumps to the functional firmware. When the running status is running on the boot firmware, the upgrade file is directly received, and the upgrade file is written into the functional segment. After the writing is completed, the process jumps to the functional firmware.

[0081] Among them, such as Figure 5 The upgrade file writing flowchart for a laser welding system firmware upgrade method provided by the present invention shows that when new firmware needs to be updated, the system first determines whether the chip is running in the boot firmware. If not, indicating that the operating status indicates that the system to be upgraded is running in the functional firmware, it is necessary to 1. delete the system code in flash identification segment 2, that is, erase the internal flash's characteristic identification segment 2. After erasing, the system identification of characteristic identification segment 2 becomes 0xFFFFFFFF. Then, the chip of the system to be upgraded is controlled to 2. jump to the boot firmware. After the jump is completed, the boot firmware 1. receives the bin file and 2. writes it to the flash functional segment. Then, it jumps again to the functional firmware and executes the upgrade error prevention process.

[0082] In addition, if yes, then it means that the running status indicates that the system to be upgraded is running in the boot firmware, then Figure 5 As shown, directly 1. receive the bin file, and 2. write it to the flash function segment, then jump to the functional firmware again and execute the upgrade error prevention process.

[0083] Furthermore, in step S108, the process of upgrading the error prevention process is executed. In this embodiment, the specific implementation method is as follows:

[0084] Jump to the functional firmware corresponding to the upgrade file; determine whether the functional firmware is the functional firmware of the main system and all the subsystems, and if so, determine whether the upgrade is complete; if not, the system to be upgraded waits for update.

[0085] Furthermore, in this embodiment, the above-mentioned process of determining whether the upgrade is complete is specifically implemented as follows:

[0086] Determine whether the system code in the feature identification segment 1 and the system code of the functional firmware corresponding to the upgrade file are the same. If so, write the system code of the system to be upgraded into the feature identification segment 2 to complete the upgrade; if not, reset the system to be upgraded, jump to the boot firmware, and the system to be upgraded waits for update.

[0087] Among them, for the system to be upgraded that executes the upgrade error prevention process, such as Figure 6 As shown in the upgrade error prevention flowchart of a laser welding system firmware upgrade method provided, the system chip corresponding to the upgraded system jumps to the newly upgraded functional firmware and then determines whether the firmware is the system firmware of the embedded device. In other words, it determines whether the functional firmware is the functional firmware of the main system or all subsystems.

[0088] If the firmware is the system firmware for this embedded device, then 1. read the system code X1 from flash identification segment 1 (i.e., the content in feature identification segment 1). 2. extract the system code Y of the functional firmware itself, i.e., the system code of the functional firmware corresponding to the upgrade file. Then, determine whether X1 equals Y. If X1 and Y are equal, 1. the firmware being upgraded is the correct system firmware. 2. Write Y to flash identification segment 2, writing the system code of the system to be upgraded to feature identification segment 2. The upgrade is complete, and the program runs normally. Therefore, if the laser welder is interrupted, such as by a power outage, the system will correctly jump to the "Normal Program Operation" branch. If X1 and Y are not equal, 1. the firmware being upgraded is the firmware for another subsystem. 2. Reset the system immediately. Resetting can effectively prevent functional abnormalities caused by upgrading the incorrect firmware. Then, 1. Reset the system to enter the boot firmware. 2. Report the missing functional firmware fault and wait for the firmware upgrade.

[0089] If the firmware is not the system firmware of this embedded device, it will be executed according to the updated firmware, and then 1. the system will be reset to enter the boot firmware, and 2. the function firmware missing fault will be reported and the firmware will be waited for the firmware upgrade. This also ensures that when the laser welder is interrupted, such as power failure, the system will jump to the "wait for firmware upgrade" branch and wait for the correct firmware to be updated, avoiding the system becoming bricked due to upgrading the wrong firmware.

[0090] It should be noted that the system code does not necessarily have to be stored inside the chip flash, but can be stored on any medium that can be saved during power failure.

[0091] In summary, all subsystems within the laser welder's embedded device are upgraded solely through the main system. Two new opcodes are added to the flash memory, and these are written independently through the boot firmware and functional firmware. By comparing the values ​​of these two opcodes at the appropriate time, the firmware update is determined to be successful, thus preventing device malfunctions and bricking caused by incorrect firmware updates. Furthermore, the use of software algorithms and design solves the challenge of upgrading multiple systems in embedded devices without sacrificing structural sealing, increasing material costs, or increasing chip security.

[0092] Corresponding to the above method embodiment, the present application also provides an embodiment of a laser welding system firmware upgrade device, Figure 7 FIG. 1 shows a schematic diagram of a laser welding system firmware upgrade device provided by an embodiment of the present application.
