In one example, the firmware server responding to the incremental update request, performing differential processing on the current version and the latest version to obtain an incremental update file, and feeding back the incremental update file to the charger, including: the firmware server responds to the incremental update request, and loads and stores the current version file corresponding to the current version and the latest version file corresponding to the latest version into an update file processing area of the firmware server; decoding and decompressing the current version file and the latest version file to obtain the current version file in a binary format and the latest version file in the binary format; respectively generating numerical fingerprints for the current version file and the latest version file to obtain a current version file digital fingerprint and a latest version file digital fingerprint; identifying a data change between the current version file and the latest version file, wherein the data change comprises: data content of file addition, file deletion and file modification; constructing an incremental data packet containing all data changes according to the data changes between the current version file and the latest version file; performing data compression processing on the incremental data packet, and packaging the compressed incremental data packet into a complete incremental upgrade file, wherein the file header information of the incremental upgrade file comprises: the version number of the current version, the version number of the latest version, the digital fingerprint of the current version file and the digital fingerprint of the latest version file; generating an incremental upgrade file digital fingerprint for the incremental upgrade file, and feeding back the incremental upgrade file and the incremental upgrade file digital fingerprint to the charger.
In this example, the firmware server responds to the delta update request by differentially processing the current version and the latest version, generating a delta upgrade file, and feeding it back to the charger. The method comprises the following specific steps: first, the firmware server loads and stores the current version and the latest version files into the update file processing area. This ensures that the server can access these files for subsequent processing. Next, the current version and the latest version files are decoded and decompressed to obtain their binary formats. This step provides the basis for subsequent data processing. Digital fingerprints are then generated for the current version and the latest version files, respectively, to identify data changes. This helps determine differences between files, including data content for file additions, deletions, and modifications. And constructing an incremental data packet containing all the changes according to the data changes between the current version and the latest version files. This helps to reduce the amount of data transmitted and improve efficiency. And carrying out data compression processing on the incremental data packet, and packaging the incremental data packet into a complete incremental upgrade file. The file header information comprises a current version number, a latest version number, a current version file digital fingerprint and a latest version file digital fingerprint, so that the integrity and the accuracy of the file are ensured. And finally, generating a digital fingerprint for the incremental upgrade file, and feeding back the file and the digital fingerprint to the charger. This helps to verify the integrity of the file and ensures the security of the upgrade process. The whole technical scheme reduces the data transmission quantity and the storage requirement by means of differential processing and incremental updating, and improves the upgrading efficiency. Meanwhile, the digital fingerprint and the integrity check ensure the accuracy and the safety of the upgrade file. In general, the technical scheme effectively improves the OTA upgrading efficiency and the safety of the battery equipment, and meets the requirements of modern automation equipment on remote upgrading technology.
In one example, identifying data changes between the current version file and the latest version file and constructing an incremental data packet containing all data changes based on the data changes between the current version file and the latest version file, includes: identifying all character strings in the current version file, sub-character strings from each position to the end of the character string in each character string, and constructing a current version suffix array of the current version file based on the sub-character strings; identifying all character strings in the latest version file, sub-character strings from each position to the end of the character string in each character string, and constructing a latest version suffix array of the latest version file based on the sub-character strings; respectively sorting the current version suffix array and the latest version suffix array by using a merging sorting algorithm by taking a dictionary sequence as a sorting reference to obtain the current version suffix array subjected to sorting and the latest version suffix array subjected to sorting; sequentially comparing suffix characters in the suffix array of the current version and the suffix characters in the suffix array of the latest version one by one until a first unmatched character is found, and recording the number of the matched characters as the longest common prefix length; continuing to execute the step of comparing the suffix characters in the suffix array of the current version and the suffix characters in the suffix array of the latest version one by one sequentially by taking the first unmatched character as a starting character until the suffix characters in the suffix array of the current version and the suffix characters in the suffix array of the latest version are compared completely, and generating an array with the longest common prefix length; determining the longest public prefix length value exceeding a preset threshold value in the longest public prefix length array, mapping the longest public prefix length value exceeding the preset threshold value to the current version suffix array and the latest version suffix array, and extracting the same character strings in the current version suffix array and the latest version suffix array; mapping the same character strings in the current version suffix array and the latest version suffix array to the current version file and the latest version file to obtain unchanged content areas between the current version file and the latest version file; respectively removing the unchanged content areas from the current version file and the latest version file to obtain a difference content area of the current version file and a difference content area of the latest version file; and determining data change between the current version file and the latest version file based on the difference content area of the current version file and the difference content area of the latest version file, and constructing an incremental data packet containing all the data change according to the data change between the current version file and the latest version file.
In this example, all the character strings in the current version file and the latest version file and all the sub-character strings of each character string are first identified, and a suffix array of the current version file and a suffix array of the latest version file are constructed based on the sub-character strings. The technical effect of this step is to prepare for the subsequent comparison and recognition data change, and the comparison and matching of the character strings can be more efficiently performed by constructing the suffix array. And then, performing sorting processing on the suffix arrays of the current version and the latest version through a merging sorting algorithm, and obtaining the suffix arrays of the current version and the latest version after sorting by taking the dictionary sequence as a sorting benchmark. The technical effect of this step is to make the subsequent character comparison more orderly and efficient, laying the foundation for identifying the longest common prefix length. And comparing the suffix characters in the suffix arrays of the current version and the latest version one by one, recording the matched character number as the longest common prefix length, and generating the longest common prefix length array. The technical effect of this step is to find the same parts in the two files, providing basis for subsequent differential content identification. After the longest common prefix length value exceeding the preset threshold is determined, mapping the longest common prefix length value to a suffix array, and extracting unchanged content areas in the two files. The technical effect of this step is to exclude parts that do not need to be changed and accurately locate the differential content of the file. And finally, eliminating unchanged content areas to obtain difference content areas of the current version file and the latest version file, determining data changes based on the difference content areas, and constructing an incremental data packet containing all the data changes. The whole technical scheme can be used for generating an incremental data packet by efficiently identifying the file change part, realizing the accurate capture and processing of the data change among the file versions, and improving the transmission efficiency of the data change and the accuracy of the file update.
In one example, determining a data change between the current version file and the latest version file based on the difference content area of the current version file and the difference content area of the latest version file, and constructing an incremental data packet containing all the data changes according to the data change between the current version file and the latest version file, including: dividing the difference content area of the current version file and the difference content area of the latest version file into a plurality of difference blocks; sequentially identifying the position of each difference block in the current version file and the latest version file; if the difference block is not identified in the current version file and is identified in the latest version file, recording the content of the difference block and the position information of the difference block in the latest version file, and adding an identifier to the difference block mark; if the difference block is identified in the current version file and is not identified in the latest version file, recording the content of the difference block and the position information of the difference block in the current version file, and marking the difference block with a deletion mark; if the difference block is identified in the current version file and the table is also identified in the latest version file, recording the content of the difference block, the position information of the difference block in the current version file and the position information of the difference block in the latest version file, and marking a mobile identifier for the difference block; and carrying out optimization combination on the recorded content and the identification content, and constructing the incremental data packet according to the optimization combination result.
In this example, the current version file and the latest version file are first divided into a plurality of difference blocks according to their difference content areas. The technical effect of this step is to subdivide the changes to the file into smaller units in order to more accurately identify and process changes to the file. Then, the positions of each difference block in the current version file and the latest version file are identified one by one. If a difference block exists in the current version file but does not exist in the latest version file, the contents of the difference block and the location information in the current version file are recorded and marked for deletion. If a difference block does not exist in the current version file but exists in the latest version file, the content of the difference block and the position information in the latest version file are recorded and marked as added. If a difference block exists in both version files, the content of the difference block and the position information in both version files are recorded and marked as moving. The technical effect of these steps is to accurately identify the change type and position information of each difference block, providing an accurate data basis for subsequent incremental data packet construction. And finally, optimizing the content and the identification of the merging record, and constructing an incremental data packet according to the optimized merging result. The technical effect of this step is to integrate all data change information into one incremental data packet, so that the change between file versions can be recorded and transmitted clearly, and the transmission efficiency of the data change and the accuracy of the file update are improved. The whole technical scheme constructs an incremental data packet containing all data changes by carefully identifying and processing the difference content among file versions, realizes the accurate capturing and processing of the file changes, and provides an efficient solution for file version management and updating.

And then, the version number of the latest version is sent to the firmware server, the latest version file is acquired, a verification fingerprint is generated, and the verification fingerprint is fed back to the charging equipment. And comparing the verification fingerprint of the latest version file with the digital fingerprint to ensure the integrity and the correctness of the latest version file. Finally, under the condition that the incremental upgrade file passes three integrity checks, the file is confirmed to pass the integrity checks. The whole technical scheme verifies the integrity of the file through multiple times of verification, and ensures the safety and reliability of the file in the transmission and updating processes, so that the firmware is effectively upgraded, and the stability of the system is ensured.

And then, carrying out standardization processing on the basic data of each key performance index, so that the basic data are converted into basic forms with the mean value and standard deviation meeting specific thresholds. This facilitates the unified processing of data for different performance indicators for subsequent comparison and evaluation. Then, a weight value is assigned to each key performance indicator, and a score for each indicator is calculated from these weight values and the underlying data. The technical effect of this step is that the scores of the various indexes are obtained by weighted evaluation of the different indexes according to the importance. And then, carrying out nonlinear logarithmic conversion and nonlinear exponential conversion on each key performance index score to obtain a first key performance index score array and a second key performance index score array.
