DETAILED DESCRIPTION

[0019] The terms "first", "second", "third", etc. in the specification of this application and the accompanying drawings are used to distinguish different objects rather than to limit a specific order.

[0020] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0021] In order to make the description of the following embodiments clear and concise, a brief introduction to the related technology is first given: UUV is an advanced device that can autonomously navigate underwater and perform various tasks. It can complete underwater operations autonomously or remotely. UUV does not require direct human control, but works based on preset programs or remote commands. It can be applied to complex and changeable underwater environments and perform efficient and accurate detection, survey, operation and rescue tasks.

[0022] At present, the storage resources of the UUV operating environment are limited, the communication conditions are strict, and higher requirements are placed on the storage and reporting of logs. However, as the equipment or system runs for a long time, the log files will gradually increase. Even if the log files are compressed, they will still occupy a large amount of storage space. Moreover, current technological development often focuses on optimizing compression algorithms, hoping to improve compression efficiency through algorithm refinement. However, in the specific application scenario of real-time log storage and extraction, existing compression technology can theoretically achieve a high compression ratio and compression speed, but when faced with log collection tasks with extremely high real-time requirements and harsh communication conditions, the problem of low compression efficiency becomes prominent. In addition, in real-time log systems, data is generated very quickly and needs to be quickly transmitted to a remote end for storage and analysis. Therefore, for the collection and display of real-time logs, the compression efficiency is low and cannot meet the efficient collection under harsh communication conditions.

[0023] In view of this, the embodiment of the present application provides a log transmission method of UUV, which is applied to a processing device. In the method, firstly, a first source code file is obtained, and the first source code file is escaped through a first mapping relationship to obtain a second source code file corresponding to the first source code file. This step can reduce the data path of the source code file before generating a log file from the source code file, thereby reducing the occupation of storage space. After obtaining the second source code file, a first log file is generated based on the second source code file. Since the data volume of the second source code file is reduced, the storage space occupied by the obtained first log file is also reduced. After obtaining the first log file, the first log file is compressed to obtain a second log file. By compressing the first log file, the data volume of the final log file is further reduced, and storage space is saved. At the same time, by the aforementioned escape and compression steps, the security of the log file is further improved, and the risk of the content of the log file being leaked is reduced. Finally, the second log file is sent to the target device according to the system configuration. It can be seen that the method can reduce the requirements for storage space and improve the security of log information.

[0024] In order to make the technical solution of the present application clearer and easier to understand, the following describes a UUV log transmission method provided by an embodiment of the present application in conjunction with the accompanying drawings. Figure 1 As shown, this figure is a flow chart of a UUV log transmission method provided in an embodiment of the present application. The UUV log transmission method includes: S101: A processing device obtains a first source code file.

[0025] The first source code file is a collection of data information collected by the UUV during underwater navigation in strict accordance with the mission requirements. The acquisition process follows a systematic process. When the UUV receives a specific mission instruction, it will start the corresponding sensor equipment according to the mission type. For example, if the mission is marine environment monitoring, the UUV will activate equipment such as temperature, salinity, depth, and water quality analyzer. These devices will collect data on parameters such as water temperature, salinity, pH, and dissolved oxygen at a certain sampling frequency, and generate the first source code file based on the collected data.

[0026] In an embodiment of the present application, a piece of data information in the first source code file is selected as an example: Log(INFO, "This is an informational message. (id=%d, text=%s)", id, text); the method provided by the present application will be described in detail based on this example.

[0027] S102: The processing device translates the first source code file through a first mapping relationship to obtain a second source code file corresponding to the first source code file.

[0028] The first mapping relationship is used to shorten the character length of the first source code file to a first character length threshold, wherein the first character length threshold is smaller than the character length of the first source code file.

[0029] The first mapping relationship is stored as a first log template.

[0030] This step can identify and remove those redundant comments, unused variable declarations, and repeated code snippets in the first source code file. Through such operations, the data volume of the source code file can be effectively reduced. When the data volume of the source code file is reduced, the space occupied by the source code file on the storage medium will also be reduced accordingly. This not only helps to improve the utilization efficiency of storage resources and avoid unnecessary waste of storage space, but also can improve the speed and performance of data processing to a certain extent, laying a good foundation for the subsequent generation of log files and other related operations.

[0031] In an embodiment of the present application, the processing device escapes the first source code file, and the obtained second source code file is: Log(INFO, "abcdefff (%d,%s)", id, text); and the first mapping relationship used in the escape process is stored as a first log template, and the first log template is: key: abcdefff; value: "helloworld.cpp INFO This is an informational message. (id=%d, text=%s)".

[0032] S103: The processing device generates a first log file based on the second source code file.

[0033] The processing device compiles the second source code file to generate an executable program, which is specially designed to generate a first log file. During the program running process, it will record the running status and key information of the program according to the preset log recording rules. For example, when the program starts, the startup timestamp is recorded; when the function is called, the function name, the passed parameters and the return value are recorded; when the program encounters an abnormal situation, the type of exception and the location where the exception occurs are recorded. The executable program will organize these recorded information according to a specific log format, such as the format of fields such as timestamp, event type, detailed description, etc., and then store it in the file system to finally form the first log file. Among them, the format of the first log file is: timestamp + key value + parameter, where the parameter is separated from the key value by special characters, such as ",".

[0034] Before compiling the first source code file, the present application first performs escape processing on the first source code file, and escapes the log information into data information with a smaller character length, which greatly reduces the log length. Not only does it greatly reduce the storage space requirements, but it also reduces the bandwidth requirements for real-time transmission, greatly improving the standardization of log output; at the same time, because the log readability is not good, the escape and extraction occur on the monitoring side, and the security is also greatly improved. The first source code file exists in the development process, and the second source code file is obtained by escaping before compilation. By compiling the second source code file, an executable program is generated. The executable program runs on the UUV, and the first log file is generated during the operation.

[0035] In an embodiment of the present application, the first log file generated by the executable program is: 6757e2f3abcdefff12345,example.

[0036] S104: The processing device compresses the first log file to obtain a second log file.

[0037] Huffman coding is a variable-length coding scheme based on the frequency of character occurrence. Its basic idea is to assign shorter codes to characters with high frequency of occurrence and longer codes to characters with low frequency of occurrence, so as to achieve the purpose of compressing data. This coding method can ensure the shortest average code length, thus achieving efficient compression effect. The following is a detailed introduction to the calculation process of Huffman coding.

[0038] Huffman coding is adaptive. It can dynamically build a Huffman tree based on the actual frequency of occurrence of characters in different log files to generate the optimal coding scheme. This means that no matter how the content of the log file changes, Huffman coding can provide good compression effects. For example, log files generated by different types of applications have different character distribution characteristics. Huffman coding can adaptively encode according to the characteristics of each log file to ensure efficient compression in all situations. The construction process of the Huffman tree is as follows: Counting character frequencies: First, you need to count the frequency of occurrence of each character in the data to be compressed.

[0039] Create nodes: Create a node for each character based on the statistical frequency of the characters. The weight of the node is the frequency of the character.

[0040] Build a minimum heap: Sort all nodes by weight from small to large, and build a minimum heap (or priority queue) to quickly find the node with the smallest weight.

[0041] Merge nodes: Take the two nodes with the smallest weights from the minimum heap and merge them into a new node whose weight is the sum of the weights of its two child nodes. Then, reinsert the new node into the minimum heap.

[0042] Repeat merging: Repeat the above merging process until there is only one node left in the heap. This node is the root node of the Huffman tree.

[0043] Huffman coding: After constructing the Huffman tree, you need to start from the root node and encode each edge (usually using 0 and 1 to represent the left subtree and the right subtree). Then, trace back from the leaf node to the root node, concatenate the codes of the edges along the way, and you will get the Huffman code of each character.

[0044] Compress data: Use the generated Huffman coding table to replace each character in the data to be compressed with its corresponding Huffman code. Since the codes of high-frequency characters are shorter and the codes of low-frequency characters are longer, the coding length of the overall data will be greatly shortened, thus achieving a compression effect.

[0045] Storage coding: The compressed coded data and the Huffman coding table are stored together. When decoding, the Huffman coding table is needed to restore the original data.

[0046] The processing device constructs a Huffman tree, performs compression processing on the first log file through the above steps, compresses the data in the first log file into a string in hexadecimal format, and obtains a second log file.

[0047] Using Huffman coding to compress the first log file can not only realize the processing of real-time logs, but also significantly reduce the size of log files. When transferring log files from one node to another (such as from a server to a log management center), the required network bandwidth is also reduced accordingly. This is particularly important in environments with limited network bandwidth. It can not only reduce transmission time, but also reduce network usage costs. Moreover, the log file compressed by Huffman coding is presented in an unreadable information format. This is because Huffman coding converts the original character sequence into a binary code consisting of 0 and 1. There is no corresponding Huffman tree, and it is difficult to restore it to the original log content. This feature plays a role in information encryption to a certain extent. Even if the log file is illegally intercepted during transmission, it is difficult for attackers to directly obtain sensitive information therein, thereby improving the security of log transmission. There is another key reason for using Huffman coding. Due to the uniqueness of Huffman coding, tampering with the compressed log file will cause errors in the decoded content. Therefore, when the target device is decoding, it is possible to determine whether the log file has been tampered with during transmission by checking the correctness of the decoding result. This mechanism effectively prevents the log data from being maliciously modified during transmission and ensures the integrity and reliability of the log data.

[0048] S105: The processing device sends the second log file to the target device.

[0049] After the processing device obtains the second log file, it uses the Advanced Encryption Standard algorithm to encrypt the second log file. After the UUV docks, according to the system configuration, it is determined whether to transmit the encrypted second log file to the target device, and the following operations are performed.

[0050] Determine whether the generated encrypted second log file needs to be reported in real time according to the system configuration, and obtain a first determination result; If the first judgment result indicates that the generated encrypted second log file needs to be reported in real time, sending the encrypted second log file to the target device; If the first judgment result indicates that the generated encrypted second log file does not need to be reported in real time, the encrypted second log file is not sent to the target device, and the second log file is stored locally in the UUV.

[0051] After receiving the second log file, the target device uses a Huffman decompression algorithm on the second log file to obtain the first log file, and escapes the first log file according to the first log template to obtain the target log file, thereby realizing the transmission of the log file.

[0052] In order to make the technical solution of the present application clearer and easier to understand, the following is a more detailed introduction to a UUV log transmission method provided by the embodiment of the present application in combination with the accompanying drawings and application scenarios. Figure 2 As shown, the figure is a schematic diagram of an application scenario of a UUV log transmission method provided in an embodiment of the present application.

[0053] In the figure, the log processor 201 processes the processing steps corresponding to S102, which is used to escape the first source code file to obtain the second source code file. This step can identify and remove those redundant comments, unused variable declarations and repeated code fragments in the first source code file. Through such operations, the data volume of the source code file can be effectively reduced. When the data volume of the source code file is reduced, the space occupied by it on the storage medium will also be reduced accordingly; the log dictionary memory 203 is used to store the first log template, and send the first log template to the log extractor 205 in the target device according to the actual situation, which is used to decode and escape the first log file to obtain the target log file; The compiler 202 processes the processing steps corresponding to S103, and is used to compile the second source code file, and escape the log information into data information with a smaller character length, which greatly reduces the log length, not only greatly reduces the requirement for storage space, but also reduces the bandwidth requirement for real-time transmission, and greatly improves the standardization of log output; the Huffman encoder 204 processes the processing steps corresponding to S104, and is used to compress the first log file to generate a second log file; the target device 205 is used to receive the second log file, decompress the second log file to obtain the first log file, and escape the first log file according to the first log template to obtain the target log file.

[0054] Based on the above content, before the second source code file is compiled into the first log file, the first source code file is escaped so that the string length of the first source code file is shortened, which can reduce the requirement for storage space, and the first log file is compressed again to further reduce the requirement for storage space. At the same time, the compressed log information is presented in a form that is difficult to directly interpret, which greatly improves its security during transmission and effectively prevents information from being illegally obtained during transmission.
