Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a MAC address recovery method, device, equipment and storage medium. Background Art

[0002] When a TV is produced, the MAC address needs to be burned in to uniquely mark the TV. However, during production, the MAC address burning may fail due to unexpected circumstances. For example: a sudden power outage during the burning process, or an abnormality of an individual movement board causes an error in the normal burning of the MAC address, or the production line uses a USB flash drive to upgrade the MAC address, but the USB flash drive is suddenly damaged and the burned data can no longer be read.

[0003] Take burning MAC address with USB as an example. Before burning, copy a segmented mac.bin file to USB. This mac.bin file contains multiple MAC addresses. Insert USB into the USB port of TV A, enter the factory menu, click the burn option, and burn MAC successfully. Unplug USB and insert into the USB port of TV B. The USB may be damaged and the file may be lost due to the TV motherboard circuit problem at the moment of inserting the USB into TV B. It may also be that the USB itself is too worn out after multiple reading and writing, and the internal storage medium is damaged, resulting in file loss. At this time, TV B prompts that the mac.bin file cannot be found and cannot be burned.

[0004] When the program fails to be burned, the first thing to consider is how to determine the next MAC address to be burned. If a MAC address is randomly selected for upgrade, the MAC address may be skipped or reused, which is not only not conducive to the management of MAC addresses, but also increases production costs. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a MAC address recovery method, apparatus, device and storage medium to improve the above-mentioned problem.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] It should be clear that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0042] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0043] See also Figure 1 and Figure 2 The first embodiment of the present invention provides a MAC address recovery method, which can be executed by a MAC address recovery device (hereinafter referred to as the recovery device), and in particular, is executed by one or more processors in the recovery device to implement the following steps:

[0044] S101, after receiving an operation to restore the MAC address, read the own MAC address and the address burning file stored in the currently connected U disk; the address burning file records multiple continuous MAC addresses within a certain address range.

[0045] In this embodiment, the recovery device may be a burned device, such as a television set. In addition, the recovery device may also be an intermediate device, which is connected to a USB flash drive and a burned device at the same time, and obtains information of the USB flash drive and the burned device to implement the MAC address recovery method of this embodiment. In this embodiment, in particular, the burned device refers to a television set that has been burned normally, that is, a burned MAC address of the device itself has been recorded inside the television set.

[0046] In this embodiment, before inserting the USB flash drive into the recovery device, the address burning file needs to be stored in the USB flash drive. The address burning file here is the source mac.bin file, which refers to a group of files including mac addresses that have been segmented before the batch production device. Among them, a possible format of the mac.bin file is as follows:

[0047] 00 1A 34 BD 93 FF 00 1A 34 BD 94 62

[0048] The mac.bin file here includes a starting MAC address (00 1A 34 BD 93 FF) and a maximum MAC address (00 1A 34 BD 94 62). Each MAC address includes two parts of information: the header information (00 1A 34) representing the manufacturer's code and the address information (BD 93 FF and BD 94 62). Therefore, the address range of this mac.bin file is from BD 93 FF to BD 94 62.

[0049] In this embodiment, when the USB flash drive is inserted into the recovery device, the recovery device can sense the access of the USB flash drive and display a corresponding interface for the user to operate. For example, the displayed interface may include a restore burned MAC address option and a restore MAC address option. The user can enter the corresponding function by triggering the corresponding option. For example, the user can generate an instruction to restore the MAC address by triggering the restore MAC address option.

[0050] S102: judging whether the own MAC address matches the address burning file according to the MAC address stored in the address burning file.

[0051] In this embodiment, when judging, first extract the header information of its own MAC address, and judge whether the header information is consistent with the header information of the MAC address in the address burning file, if consistent, then judge that the header information of the two matches. If inconsistent, then prompt the information of mismatch, so that the user can change the USB flash drive or change the address burning file.

[0052] Then, the address information of the own MAC address is extracted, and it is determined whether the address information is within the address range recorded in the address burning file.

[0053] For example, assuming that the MAC address of the recovery device itself is 01 1A 34 BD 94 60, since its header information is different from the header information of the MAC address stored in the address burning file, the two do not match.

[0054] For another example, assuming that the MAC address of the recovery device is 00 1A 34 BD 94 65, although its header information is the same as the header information of the MAC address stored in the address burning file, its address information is not within the address range of the MAC address stored in the address burning file, so the two do not match.

[0055] For another example, assuming that the MAC address of the recovery device is 00 1A 34 BD 94 50, its header information is the same as the header information of the MAC address stored in the address burning file, and the address information is also within the address range of the MAC address stored in the address burning file, so the two match.

[0056] S103, when it is determined to be a match, modify the starting MAC address marked in the address burning file according to the own MAC address to obtain a modified address burning file; wherein the starting MAC address is the MAC address used by the address burning file when it is burned next time.

[0057] In this embodiment, specifically, after a successful match, the recovery device converts its own MAC address into long integer data, and adds a preset hysteresis value to the long integer data value to generate a recovery MAC address, and then modifies the address burning file through a file byte IO stream so that the starting MAC address of the address burning file is the recovery MAC address.

[0058] In this embodiment, the hysteresis value is determined according to the burning relationship between the recovery device and the device that failed to burn. For example, if the recovery device is the first N devices of the device that failed to burn, the hysteresis value is N. In particular, in order to avoid errors, the hysteresis value is preferably 1 in this embodiment, that is, the device before the device that failed to burn is taken as the recovery device.

[0059] In this embodiment, taking the hysteresis value equal to 1 as an example, at this time, if the MAC address of the recovery device itself is 001A 34 BD 94 50, the recovery MAC address is 00 1A 34 BD 94 51. Then the modified address burning file becomes: 00 1A 34 BD 94 51 00 1A 34 BD 94 62.

[0060] S104, verifying the starting MAC address of the modified address burning file, and generating a prompt for MAC address recovery after successful verification.

[0061] In this embodiment, after the modification is completed, the recovery device reads the starting MAC address of the modified address burning file again, and determines whether the starting MAC address is equal to the recovery MAC address. If they are equal, the verification is successful and a prompt for MAC address recovery is generated. If the verification fails, a prompt for unsuccessful MAC address recovery is generated.

[0062] See also Figure 3 In this embodiment, when the MAC address is successfully restored, the user can unplug the USB flash drive from the recovery device, and then insert the USB flash drive into the next device that needs to be burned (such as a TV) to burn the MAC address of the TV. The MAC address of the burned TV is 00 1A 34 BD 94 51, thereby realizing the continuous use of the MAC address without the problem of the MAC address being skipped or reused.

[0063] To sum up, after the MAC address burning fails, this embodiment restores the address burning file by inserting the USB flash drive including the source address burning file into the recovery device that has completed the burning before, so that the starting MAC address of the restored address burning file is consistent with the starting MAC address of the address burning file when the burning fails, thereby avoiding the problem of MAC address being skipped or reused, and facilitating the management of MAC addresses.
