DETAILED DESCRIPTION

[0032] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0033] It should be understood that in the embodiments of the present disclosure, the character " / " generally indicates that the objects associated with each other are in an "or" relationship. The terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0034] As the level of aircraft informatization and intelligence becomes higher and higher, the complexity of aircraft increases greatly, and the amount of data from aircraft flight tests increases significantly.

[0035] The current method of processing flight test data is: after the flight, the flight test data recorded by the onboard recorder is unloaded to the data server through professional unloading software, and provided to data processing personnel for data processing.

[0036] However, the current method of processing flight test data is time-consuming and affects the efficiency of flight tests.

[0037] For example, as the level of aircraft informatization and intelligence increases, the complexity of aircraft increases greatly, and the amount of flight test data of aircraft surges. Real-time processing of flight test data is an important part of flight test data processing, which can quickly provide key parameters after solution to flight test engineers for flight test risk assessment. The current airborne real-time data processing system needs to load configuration information on the aircraft before flight, and after the flight, the flight data recorded by the airborne recorder is unloaded to the data server through professional unloading software and bit stream analysis is performed as needed, and then provided to the data processing personnel for data preprocessing and secondary processing. However, the above processing mode will cause the problem of poor timeliness of flight test engineers to obtain data and low efficiency of flight tests. Moreover, as the level of aircraft informatization and intelligence increases, the amount of airborne test data increases dramatically, and the current system is difficult to meet the demand for rapid acquisition of flight test data.

[0038] Against this background, the present invention provides an onboard high-speed data dump device, which can improve the timeliness of obtaining flight test data, thereby improving the efficiency of flight tests.

[0039] In an exemplary embodiment, the airborne data high-speed dump device provided by the present disclosure can be used to obtain flight test data of an aircraft and transmit it to a ground-end fusion server.

[0040] Figure 1 The schematic diagram of the principle of the airborne data high-speed dump device provided by the embodiment of the present disclosure. Figure 1 As shown, the device may include a high-concurrency airborne data processing module, a file management module, and a data transmission module.

[0041] The high-concurrency airborne data processing module is connected to the airborne data recorder, the data reservation system, the file management module, and the data transmission module respectively, and the file management module is connected to the data transmission module. The high-concurrency airborne data processing module is used to obtain the flight mission reservation form from the data reservation system, extract the flight test data from the airborne data recorder according to the flight mission reservation form, and process the flight test data. The file management module is used to manage the attribute information of the flight test data. The data transmission module is used to obtain the processed flight test data in the high-concurrency airborne data processing module and the attribute information in the file management module, and transmit the processed flight test data and attribute information to the ground fusion server.

[0042] Exemplarily, the airborne data high-speed dump device is installed on the aircraft and may include a high-concurrency airborne data processing module, a file management module, and a data transmission module. The high-concurrency airborne data processing module can be connected to the airborne recorder on the aircraft externally, and can also be connected to the data reservation system on the ground end through the 5G wireless network, and internally connected to the file management module and the data transmission module in the airborne data high-speed dump device. The high-concurrency airborne data processing module can obtain the flight mission reservation form from the data reservation system, and then parse the flight mission reservation form, extract the flight test data from the airborne data recorder according to the information contained in the parsed flight mission reservation form, and determine the priority of each data stream according to the packet frequency corresponding to each data stream in the flight test data, parse each data stream according to the priority of each data stream, and store the parsed data streams in real time in chronological order through the time positioning algorithm. Among them, the flight mission reservation form may include an aircraft header file, a processing parameter list file, system configuration information, etc. The file management module is connected to the data transmission module, and can store and manage the attribute information of the flight test data, wherein the attribute information of the flight test data may include the file information of the flight test subject and the processing information of the flight test data, the file information of the flight test subject may include the corresponding relationship between the flight test data and the flight test subject, and the processing information of the flight test data may include the storage location and processing method of the flight test data. The data transmission module is connected to the high-concurrency airborne data processing module and the file management module respectively, and can obtain the processed flight test data in the high-concurrency airborne data processing module and the attribute information in the file management module, and transmit the processed flight test data and attribute information to the ground-end fusion server.

[0043] For example, the high-concurrency airborne data processing module can perform high-concurrency streaming airborne data multi-threaded processing, which is divided into three stages: subject reservation task preprocessing, flight subject file parameter equation solution, and subject reservation task tail processing. In the subject reservation task preprocessing stage, the "first process" generates flight subject file data processing parameters according to the needs of the data reservation task, and transmits them to other processes through the multicast communication mechanism; other streaming processes receive data processing parameters through the networking communication mechanism. Among them, the "first process" is the main process, responsible for subject task data division, other process scheduling management, recording task result feedback and result statistical analysis; other processes are slave processes, there are multiple slave processes, which are responsible for parameter file solution according to the division and dispatch of the main process and feedback of processing results to the main process. Before the cyclic calculation of the flight subject file parameter equation calculation stage, each process listens for asynchronous messages through a non-blocking point-to-point communication mechanism. Each process loop divides a multi-stream data subset from the flight subject data set for high-concurrency data processing, including the resolution of INET data, IENA data, bus data, and fiber data; for data streams of different frequencies, the priority of the corresponding thread needs to be designed, otherwise the high-frequency data stream may not be allocated enough time slices during thread scheduling, resulting in too slow data parsing and eventually program abnormality. Among them, the highest priority: the data packet frequency is greater than or equal to 512Pag / s; higher than the normal priority: the data packet frequency is greater than or equal to 128Pag / s; normal priority: the data packet frequency is less than 128Pag / s. When the flight data processing result of a process triggers the termination condition, this process sends an asynchronous message to all other processes through a non-blocking point-to-point communication mechanism to mark the termination of this process task. In the loop interval of the loop execution of multi-stream data subset processing, each slave process checks the asynchronous message. If a process has marked the task termination, it exits the peer calculation loop. In the tail processing stage of the subject reservation task, the "first process" performs result statistical analysis, and then all high-concurrency airborne data processes exit the task.

[0044] The disclosed embodiment proposes an airborne data high-speed dump device, which may include a high-concurrency airborne data processing module, a file management module, and a data transmission module. The high-concurrency airborne data processing module is connected to the airborne data recorder, the data reservation system, the file management module, and the data transmission module, respectively, and the file management module is connected to the data transmission module. The high-concurrency airborne data processing module is used to obtain a flight mission reservation form from the data reservation system, extract flight test data from the airborne data recorder according to the flight mission reservation form, and process the flight test data. The file management module is used to manage the attribute information of the flight test data. The data transmission module is used to obtain the processed flight test data in the high-concurrency airborne data processing module and the attribute information in the file management module, and transmit the processed flight test data and attribute information to the ground-end fusion server. By modularly designing the airborne data high-speed dump device, each module is used to complete the processing and transmission of the flight test data, which greatly improves the timeliness of obtaining the flight test data, thereby improving the efficiency of the flight test.

[0045] In some embodiments, Figure 1 As shown, the above-mentioned airborne data high-speed dump device may also include: a monitoring service module.

[0046] The monitoring service module is connected to the high-concurrency airborne data processing module, the data transmission module, and the file management module respectively; the monitoring service module is used to monitor the status of the high-concurrency airborne data processing module, the data transmission module, and the file management module. The monitoring service module may include a network service unit, a hardware monitoring unit, a transmission monitoring unit, a data monitoring unit, and a receiving monitoring unit. Among them, the network service unit is used to monitor the network status; the hardware monitoring unit is used to monitor the hardware working status; the transmission monitoring unit is used to monitor the working status of the data transmission module; the data monitoring unit is used to monitor the working status of the high-concurrency airborne data processing module; and the receiving monitoring unit is used to store the monitoring information of the monitoring service module.

[0047] Exemplarily, the airborne data high-speed dump device may further include a monitoring service module, which is respectively connected to the high-concurrency airborne data processing module, the data transmission module, and the file management module, and is used to monitor the status of the high-concurrency airborne data processing module, the data transmission module, and the file management module. The monitoring service module may include a network service unit, a hardware monitoring unit, a transmission monitoring unit, a data monitoring unit, and a receiving monitoring unit, and the receiving monitoring unit is respectively connected to the network service unit, the hardware monitoring unit, the transmission monitoring unit, and the data monitoring unit. Among them, the network service unit may also be called a global wide area network (world wide web, Web) service unit, and the Web service unit can monitor the network connection status of the airborne data high-speed dump device. The hardware monitoring unit can monitor the working status of the central processing unit (CPU), memory, disk, etc. For example, when the hardware monitoring unit detects that disk A has no storage space, it can inform the high-concurrency airborne data processing module data by sending a signal to store the data to disk B. The transmission monitoring unit can monitor and warn the working status of the data transmission module, monitor the status of the flight test data transmission process, and issue an abnormal alarm when the flight test data transmission status is abnormal. The data monitoring unit can monitor and warn the working status of the high-concurrency airborne data processing module and monitor the solution status of the flight test data. The receiving monitoring unit can store all monitoring information of the monitoring service module.

[0048] This embodiment can also include a monitoring service module by limiting the airborne data high-speed dump device, and the monitoring service module is connected to the high-concurrency airborne data processing module, the data transmission module, and the file management module respectively, and is used to monitor the status of the high-concurrency airborne data processing module, the data transmission module, and the file management module. The monitoring service module may include a network service unit, a hardware monitoring unit, a transmission monitoring unit, a data monitoring unit, and a receiving monitoring unit. Among them, the network service unit is used to monitor the network status; the hardware monitoring unit is used to monitor the hardware working status; the transmission monitoring unit is used to monitor the working status of the data transmission module; the data monitoring unit is used to monitor the working status of the high-concurrency airborne data processing module; and the receiving monitoring unit is used to store the monitoring information of the monitoring service module. The network connection status of the airborne data high-speed dump device and the working status of each module can be monitored and all monitoring information can be stored, so as to ensure the normal operation of the airborne data high-speed dump device, and when an abnormal situation occurs, the abnormal position can be quickly located through the stored monitoring information, further improving the working efficiency of the airborne data high-speed dump device.

[0049] In some embodiments, such as Figure 1As shown, the above-mentioned high-concurrency airborne data processing module may include a data parsing unit, a data solving unit, a data packetizing unit, a data compression unit and a data storage unit.

[0050] The data analysis unit, the data calculation unit, the data subpackaging unit, the data compression unit and the data storage unit are connected in sequence; the data analysis unit is used to obtain the flight mission reservation form from the data reservation system, and parse the flight mission reservation form to obtain the parsing result; the data calculation unit is used to extract the flight test data from the airborne data recorder according to the parsing result of the data analysis unit, and calculate the flight test data to obtain the calculation result; the data subpackaging unit is used to perform data segmentation on the calculation result of the data calculation unit; the data compression unit is used to compress the flight test data processed by the data subpackaging unit; the data storage unit is used to store the flight test data compressed by the data compression unit.

[0051] Exemplarily, the high-concurrency airborne data processing module may include a data parsing unit, a data solving unit, a data subpackaging unit, a data compression unit, and a data storage unit. The data parsing unit, the data solving unit, the data subpackaging unit, the data compression unit, and the data storage unit are connected in sequence. The data parsing unit may obtain a flight mission reservation form from the data reservation system, and then parse the contents contained in the flight mission reservation form to obtain a parsing result recognizable by the airborne data high-speed dump device, wherein the flight mission reservation form may include an aircraft header file, a processing parameter list file, system configuration information, etc., such as aircraft model, model, performance and working status of each device of the aircraft, flight altitude, longitude and latitude of the aircraft, flight subject, flight mission, flight time period, and other information of the aircraft. The data solving unit may extract flight test data from the airborne data recorder according to the parsing result of the data parsing unit, divide the flight test data into at least two data streams, and perform enhanced network enhanced telemetry integrated network (INET) and network telemetry standard (IENA) network packet parsing on the flight test data according to the packet frequency of the at least two data streams to obtain a parsing result. The data packetization unit can perform data slicing on the calculation results of the data calculation unit to obtain the slicing results of the flight test data. Since there is a lot of subject information after the calculation, the data of multiple subjects need to be combined and stored, and the data needs to be spliced ​​and stored in time. The time positioning algorithm is used to complete the time positioning and storage of the data. When a data stream in the receiving subject receives data, the subject to be stored will be stamped with a timestamp. The received data will then be compared with this data stamp for data time positioning. When the time of all streams exceeds the timestamp by 1s, it means that the data within 1s has been prepared and the data can be stored. The data compression unit can compress the flight test data after the data packetization unit has been sliced. Since the flight test is long and the test parameter capacity is large, up to hundreds of gigabytes (GB), it occupies a large amount of disk space, and the copy and unloading of data will cause a large amount of disk space to be occupied. The transmission process will bring a waste of time. The amount of data can be reduced by means of data compression, which greatly alleviates the disk occupancy and the time-consuming data transmission. The DEFLATE compression algorithm is used, and the data will be saved in the gzip data format. Deflate is the default algorithm for gzip files and is also a data stream compression algorithm. You can use the LZ77 compression algorithm first, and then use huffman encoding. The compression tree is defined by the Deflate specification, and no additional space is required to store this tree. LZ77 compression: When compressing data, there are two situations when doing phrase matching between the forward buffer and the sliding window. When no match is found, the unmatched symbols are encoded into symbol tags, otherwise they can be encoded.The phrase tag contains the offset of the sliding window (calculated from the start of the match), the number of symbols in the match, and the first symbol in the forward buffer after the match ends. The matching step is to find out whether there is a match in the forward buffer for the string in the current window, and not to continue advancing the window and pre-reading area; if there is a match, use a triplet to mark the current string and move forward by the number of matching symbols + 1; continue to search for matches in the window (note that the sliding window searches for matching strings and the preset window searches for the cutoff bit), and return to 1 and repeat until the match is completed. Deflate uses an improved version of the LZ77 algorithm: only repeated strings of more than three bytes are encoded. In gzip<len,offset> The length of the tag is 23 bits. If the repetition length is less than this value, the compression fails. After the flight test data is converted into a length distance tag, it is represented by Huffman coding. In this process, the coding table (the corresponding relationship of Huffman coding) is first generated. The specific compression size depends on the bit field of the fine allocation structure. In the Huffman algorithm, the prefix code needs to maintain uniqueness in the streaming transmission of variable-length coded data, and must meet the conditions of unique decodability. Different prefix codes can be uniquely decodable, which can simplify decoding but increase the length of the code. Huffman coding is a greedy strategy optimal prefix code based on probability distribution. Huffman coding can effectively compress data, and the compression rate depends on the information redundancy of the data itself. When calculating the probability of occurrence of each symbol in the data, the construction code tree is constructed from small to large, from bottom to top, so that the average length of the final code is the shortest. It is also uniquely decodable. Compressed GZIP file format Gzip file = Gzip header + actual content of deflate encoding + Gzip tail. The data storage unit is composed of access to the Redis buffer, storage middleware conversion, and high-speed partition storage, and can store the flight test data compressed by the data compression unit. Among them, the Redis buffer is accessed, and the high-concurrency airborne data stream is accessed to the multi-buffer queue 1-m, which can include cache data stream protocols and adaptive adjustment of buffer queue lengths, etc., to buffer high-concurrency airborne data streams of different types and lengths. Each buffer queue period receives the stream processing result stream, monitoring service stream, and file management stream of the upstream high-concurrency airborne data processing node. The cache data packet includes a header, a data field, and a checksum. The header includes the IP addresses of the source node and the destination node; the data field includes the length of the data packet and a data area of ​​variable size. Sequence number 1 represents the stream processing result stream, sequence number 2 represents the monitoring service stream, and sequence number 3 represents the file management stream; the checksum MD5 checksum hash value is used to verify the completeness of the data packet. The storage middleware conversion includes a buffer monitoring module, a multi-threaded read-write module, and a thread dynamic management module.Among them, the buffer monitoring module periodically collects the content of the Redis buffer queue monitoring table, calculates the buffer queue load information and synchronizes it to the Redis buffer load table; the multi-threaded read and write module prioritizes the allocation of threads to the buffer with the highest storage load, and periodically collects different queue load information and stores it in batches in the specified database; the thread dynamic management module dynamically adjusts the number of threads according to the read and write pressure of the concurrent thread pool to improve the utilization of system storage resources. High-speed partition storage: The storage layer uses relational databases and columnar databases for storage. The stream data of the processing results has real-time writing and query requirements and is stored in the columnar cluster, and row keys, timestamps, and pre-partition management are designed; while the monitoring service flow data and file management flow are stored in the relational database because the data volume is controllable.

[0092] For example, Figure 6 For the implementation method, specific implementation methods and beneficial effects of the monitoring service module, please refer to the above description of the monitoring service module, which will not be repeated here.

[0093] In a specific embodiment, taking aircraft A as an example, when aircraft A is preparing on the ground before flight, the airborne data high-speed dump device establishes a connection with the data reservation system through the 5G base station network, and the high-concurrency airborne data processing module obtains and parses the flight mission reservation order information of aircraft A, wherein the flight mission reservation order information may include an aircraft header file, a processing parameter list file, system configuration information, etc., and the flight mission reservation order information can be used as the input of the high-concurrency airborne data processing module. After the onboard recorder of the aircraft is powered on, the high-concurrency airborne data processing module can process the flight test data according to the "merge-process-diverge" method. First, the flight test data is obtained from the onboard recorder, and the multi-subject processing parameters are merged according to the basic information of the parameters according to the flight mission reservation form. It can also be understood that the multi-subject processing parameters are classified according to the basic information of the parameters according to the flight test subjects to form a merged parameter list. At this time, the parameters in the merged parameter list will not be repeated and there will be no missing, and the list is a parameter list that needs to be processed during real-time processing. Then, during real-time processing, read and analyze each network packet data, extract the code value and convert the physical quantity of the parameters in the merged parameter list, and store the processed result data in the buffer by setting the buffer reasonably. Finally, after the processing is completed, according to the data diversion method, each parameter in the multiple subjects is read from the buffer and written into the result file of the multiple subjects. At this point, the real-time processing of multi-stream and multi-subject data is completed, and the result data is stored at the same time. Due to the large amount of current flight test data and the possibility of unstable links during the transmission process, considering the need for data transmission after the flight, the files are stored in fragments during the storage process. When the stored file is larger than 1G, the file is closed and a new file is created for storage. This greatly facilitates the data storage process and data transmission after the flight. After aircraft A completes its flight mission and lands on the ground, the onboard high-speed data dump device can determine the flight status of the aircraft through the aircraft's reverse thrust signal and landing gear signal, and request access to the 5G base station network. During the period from aircraft A landing on the runway to taxiing to the apron, the data transmission module verifies the result data and transmits it to the ground-end fusion server. After the transmission is completed, the ground-end fusion server notifies the data transmission module to complete the transmission, and the transmission process ends. The flight test data is pushed to the flight test engineer to facilitate rapid flight test evaluation.
