[0020] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0021] The following describes a file upgrade method and an upgrade apparatus for a wearable device according to an embodiment of the present application with reference to the accompanying drawings.

[0022] In response to the problems mentioned in the above background technology, such as slow upgrade speed, low upgrade efficiency, poor upgrade practicality, and impact on user experience due to direct upgrading of original files, the present application provides a file upgrade method for a wearable device, which obtains a compressed file from an external device, where the compressed file is obtained by the external device using a compression algorithm to compress the upgrade file; the compressed file is upgraded to obtain a target file. Since the compressed file of the file to be upgraded is upgraded directly, the file upgrade efficiency of the wearable device can be effectively improved, and the practicality and reliability of the file upgrade can be effectively guaranteed.

[0023] Figure 1 The present invention is a flowchart of a file upgrade method for a wearable device according to an embodiment of the present application.

[0024] This embodiment is illustrated by taking the file upgrade method of a wearable device as a file upgrade apparatus for a wearable device.

[0025] In this embodiment, the file upgrade method of the wearable device can be configured in a file upgrade device of the wearable device. The file upgrade device of the wearable device is set in the wearable device, such as a smart bracelet, a smart helmet, etc., without limitation.

[0026] This embodiment takes the file upgrade method of a wearable device being configured in an electronic device as an example.

[0027] It should be noted that the execution subject of the embodiment of the present application may be, for example, a processor of a wearable device in hardware, or may be, for example, a related background service of the wearable device in software, without limitation.

[0028] like Figure 1 As shown, the file upgrade method of the wearable device includes:

[0029] S101: Obtain a compressed file from an external device, where the compressed file is obtained by compressing the upgrade file using a compression algorithm by the external device.

[0030] The above-mentioned external device may be, for example, a server or an external electronic device, which is used to perform functional upgrades on the wearable device, such as firmware version or UI resource updates.

[0031] The embodiment of the present application obtains a compressed file from an external device. The compressed file is obtained by the external device using a compression algorithm to compress the upgrade file. Therefore, compared with the related technology that directly upgrades the original file in the wearable device, the embodiment of the present application obtains a compressed file from an external device, such as a compressed file, which is obtained by the external device using an open source compression algorithm to compress the upgrade file, thereby achieving upgrade processing of the compressed file to obtain the target file, thereby realizing rapid upgrade of the files in the wearable device.

[0032] Optionally, the compression algorithm is any one of the following: QuickLZ compression algorithm, FastLZ compression algorithm, LZF compression algorithm or zlib compression algorithm, or may be any other open source compression algorithm, without limitation.

[0033] That is to say, the above-mentioned compressed file is obtained by pre-compressing the upgrade file by the external device using any of the above-mentioned compression algorithms. When the external device compresses the compressed file, a communication link can be established with the wearable device, thereby sending the compressed file to the wearable device based on the communication link. Thus, the wearable device can obtain the compressed file from the external device.

[0034] S102: Upgrade the compressed file to obtain a target file.

[0035] After obtaining the compressed file from the external device, the wearable device can directly upgrade the compressed file to obtain the target file. For example, a pre-configured script file can be called to execute the script file to upgrade the compressed file to obtain the target file.

[0036] In the present application embodiment, see Figure 2The compressed file carries a first verification code, which is obtained by encoding the upgrade file using an encoding algorithm by an external device. The compressed file is upgraded to obtain a target file, including:

[0037] S201: Upgrade the compressed file to obtain a target compressed file.

[0038] The first verification code mentioned above is used to assist in the legitimacy verification of the subsequent decompressed files, thereby effectively ensuring the security and practicality of the upgrade.

[0039] Optionally, the encoding algorithm is a CRC32 algorithm, or may be any other possible encoding algorithm, which is not limited.

[0040] After obtaining the compressed file from the external device, the wearable device can directly upgrade the compressed file to obtain a target compressed file. The file obtained by upgrading the compressed file can be called a target compressed file.

[0041] S202: Decompress the target compressed file to obtain a decompressed file.

[0042] After the upgrade, the target compressed file can be decompressed to obtain a decompressed file. That is to say, the wearable device directly upgrades the compressed file to obtain the target compressed file, and then decompresses the target compressed file. At this time, the decompression algorithm corresponding to the above-mentioned compression algorithm can be used to decompress the target compressed file to obtain a decompressed file.

[0043] After decompressing the target compressed file and obtaining the decompressed file, the file data corresponding to the decompressed file is also written into the target address, thereby realizing standardized storage of the file data corresponding to the decompressed file, assisting the sequential reading of subsequent file data to generate a corresponding second verification code, and ensuring the reliability of the application of the file upgrade method.

[0044] S203: Generate a second verification code according to the decompressed file.

[0045] In the above, the file data corresponding to the decompressed file is written into the target address, and the file data can also be read from the target address; the file data is encoded according to the encoding algorithm, so as to generate a second check code.

[0046] That is to say, after decompressing the target compressed file and obtaining the decompressed file, the present application also reads the file data from the target address; encodes the file data according to the encoding algorithm to generate a second verification code, and the second verification code is used to match the above-mentioned first verification code, so as to verify the legitimacy of the decompressed file, thereby ensuring the security of the upgrade.

[0047] It should be noted that the encoding algorithm for obtaining the second check code is the same as the encoding algorithm for obtaining the first check code.

[0048] S204: Verify the legitimacy of the decompressed file according to the first verification code and the second verification code.

[0049] In some embodiments, the legitimacy of the decompressed file is verified based on the first verification code combined with the second verification code, and it can be determined whether the matching status of the first verification code and the second verification code meets the preset matching status; if it meets the set matching status, it is determined that the legitimacy verification of the decompressed file has passed, which is simple to implement and does not consume too many computing resources.

[0050] For example, if the matching states of the first verification code and the second verification code are consistent within the error range, it is determined that the matching states of the first verification code and the second verification code meet the set matching state; otherwise, it is determined that the matching states of the first verification code and the second verification code do not meet the set matching state.

[0051] Of course, any other possible method may be selected to verify the legitimacy of the decompressed file based on the first verification code in combination with the second verification code, and there is no limitation to this.

[0052] S205: If the legality verification passes, the decompressed file is used as the target file.

[0053] The target file is the upgraded file corresponding to the file to be upgraded.

[0054] In this embodiment, a compressed file is obtained from an external device, where the compressed file is compressed by the external device using a compression algorithm to compress the file to be upgraded; the compressed file is upgraded to obtain a target file. Since the compressed file of the file to be upgraded is upgraded directly, the file upgrade efficiency of the wearable device can be effectively improved, and the practicability and reliability of the file upgrade can be effectively guaranteed.

[0055] This application also provides an example of an external device using a compression algorithm to compress an upgrade file to obtain a compressed file, which is specifically described as follows:

[0056] In some embodiments, the file to be upgraded includes n data segments, and the compressed file includes n compressed data segments, wherein the data volume of n-1 data segments is equal to a preset value, and the data volume of the remaining data segment is less than or equal to the preset value, and n is a positive integer greater than 1.

[0057] Among them, the compressed file obtained by the external device compressing the file to be upgraded using a compression algorithm can be that the file to be upgraded is divided into n data segments in sequence, thereby, a segment-by-segment compression method can be adopted to compress each data segment of the file to be upgraded, and the compressed file includes n compressed data segments, among which the data volume of n-1 data segments is equal to a preset value, and the data volume of the remaining data segment is less than or equal to the preset value, and n is a positive integer greater than 1.

[0058] The preset value may be, for example, 4 KB.

[0059] It should be noted that the minimum erase unit of NOR / NAND flash memory used by embedded devices is 4KB, so the compressed file is generally much larger than 4KB, otherwise there is no need to compress it.

[0060] For example, the preset algorithm may be an open source compression and decompression algorithm. The compression method of the embodiment of the present application includes:

[0061] Step S1: Determine whether the remaining data size of the current uncompressed file is greater than 4KB, wherein, if it is not less than 4KB, execute step S2, otherwise execute step S4.

[0062] Step S2: Use a compression algorithm (such as QuickLZ, FastLZ, LZF, zlib, etc.) to compress the initial 4KB data segment of the file, and write the compressed data into the compressed file.

[0063] Step S3: Subtract 4KB from the data size of the current uncompressed file, and re-execute step S1.

[0064] Step S4: Use a compression algorithm to compress the remaining data of the current file that is less than 4KB, and write it into a compressed file.

[0065] It is understandable that after compression, different compression algorithms have different compression rates (e.g. QuickLZ about 47%, FastLZ about 50%, LZF about 50%, zlib about 37%).

[0066] It should be noted that, for the compressed file, the embodiment of the present application can add an identifier for legitimacy verification, such as calculating CRC32 for the upgrade file, and recording CRC32 in the identifier for legitimacy verification to generate a first verification code.

[0067] In some other embodiments, when the file to be upgraded includes n data segments, the compressed file includes n compressed data segments, wherein the data volume of n-1 data segments is equal to the preset value, and the data volume of the remaining data segment is less than or equal to the preset value, and n is a positive integer greater than 1, the above Figure 2The step of decompressing the target compressed file to obtain the decompressed file in the embodiment can also be specifically refined as follows:

[0068] Optionally, the target compressed file includes multiple compressed data segments, and the compressed data segments correspond to the data segments one by one. Decompressing the target compressed file to obtain the decompressed file includes: decompressing each compressed data segment segment by segment to obtain the decompressed file.

[0069] Optionally, the target compressed file includes multiple compressed data segments, the compressed data segments correspond to the data segments one-to-one, the compressed data segments have corresponding serial numbers, and decompressing the target compressed file to obtain a decompressed file includes: decompressing the compressed data segments to obtain decompressed data corresponding to the compressed data segments; and combining multiple decompressed data according to the serial numbers of the compressed data segments to obtain a decompressed file.

[0070] Therefore, a flexible decompression method is provided, which effectively improves the applicability of the upgrade method, can effectively adapt to the upgrade requirements in a variety of different application scenarios, and improves the user experience.

[0071] The steps of decompressing each compressed data segment piece by piece to obtain the decompressed file can be exemplified as follows:

[0072] Step S1: Determine the identification mark of the currently undecompressed file. If the identification fails, execute step S8; otherwise, execute step S2.

[0073] Step S2: Determine the data header of the currently uncompressed file and whether the decompressed data volume is 4KB.

[0074] Step S3: If the amount of data after decompression is 4KB, use the decompression algorithm corresponding to the compression algorithm to decompress the compressed data segment specified by the current data header, and then write the decompressed 4KB data to the target address.

[0075] Step S4: If the amount of decompressed data is less than 4KB, execute step S6; otherwise, execute step S5.

[0076] Step S5: Subtract the data size of the compressed data segment from the data size of the current undecompressed file, and find the next data header, and execute step S2.

[0077] Step S6: decompress the remaining data and write the decompressed data to the target address.

[0078] Optionally, in one embodiment of the present application, the method of the embodiment of the present application further includes: verifying the legitimacy of the decompressed file based on the first verification code in combination with the second verification code; if the legitimacy verification passes, using the decompressed file as the target file.

[0079] For example, CRC32 calculation is performed on the decompressed file at the target address to obtain a second check code, which is compared with the first check code in the identification mark. If they match, the decompression is considered successful, otherwise the decompression is considered failed.

[0080] Specifically, since most resource content has a high duplication rate, the compression rate is also high on average. Taking QuickLZ as an example, the original file size is 234KB, the compressed size is 45KB, and the compression rate is about 20%. On the same MI8SE phone, the download time can be reduced from the original 26 seconds to 4 seconds. It takes 10 seconds to decompress the 45KB compressed file into the 234KB original file, and the total time is 14 seconds. The total upgrade time is saved by 12 seconds. Therefore, the upgrade efficiency is effectively improved, and the user upgrade experience for wearable devices is improved.
