Description

TECHNICAL FIELD

[0001] The application belongs to the field of avionics, and particularly relates to a cockpit instrument reconstruction method for flight debriefing, which can be used for accurate data display and picture reconstruction of cockpit instruments for flight debriefing. BACKGROUND

[0002] In modern aviation flight debriefing, in order to comprehensively and accurately review the flight task, a large amount of flight data recorded by the flight parameter recording system needs to be displayed on the cockpit instruments. The traditional cockpit instrument data display method lacks effective management in the data transmission process, and different types of data blocks are easily confused during transmission, which makes it difficult for the cockpit instruments to receive data. In addition, after receiving the data, the cockpit instruments cannot reasonably reconstruct and display the data in the corresponding picture area according to the actual meaning and function of the data, which greatly affects the efficiency and quality of flight debriefing. To solve the above problems, the cockpit instrument reconstruction method needs to be improved to meet the high-precision requirements of flight debriefing. SUMMARY

[0003] The purpose of the present application is to design a cockpit instrument reconstruction method for flight debriefing, which optimizes the data transmission and processing mechanism, realizes accurate reception of data sent by the flight debriefing system to the cockpit system, and correctly reconstructs and displays the data.

[0004] Technical scheme: In order to achieve the above-mentioned purpose of the application, a cockpit instrument reconstruction method for flight debriefing is designed, which constructs a whole-process processing mechanism of "data encapsulation-broadcast transmission-accurate analysis-mapping display", sets a unique identifier for different data blocks, combines data analysis, identification and pre-set display area mapping relationship, ensures that flight parameter data can be accurately mapped to the specified area of the cockpit system picture, and realizes efficient data interaction and picture reconstruction between flight debriefing and cockpit system.

[0005] Further, the construction process of the whole-process processing mechanism of "data encapsulation-broadcast transmission-accurate analysis-mapping display" in the reconstruction method described above includes the following steps: Step S1: encapsulate the original flight parameters to form a data transmission unit containing aircraft type, identifier and data content, and send it to the cockpit system by broadcast; Step S2: after receiving the data, the cockpit system verifies the format to exclude invalid data, and then extracts the data stream content through the analysis algorithm; Step S3: identify the data blocks one by one based on the identifier information, determine their data types, and establish the corresponding relationship between the data blocks and the identifiers; Step S4: According to the preset mapping relationship between the identifier and the reconstructed picture display area, reconstruct and display to the target area of the corresponding instrument picture according to the specified format and rules, and realize the visualization of the flight data.

[0006] Further, in step S1, the flight review system collects various data of the flight, divides the data into different data blocks, assigns a unique identifier to each data block, encapsulates the identifier and the corresponding data block through a specific data encapsulation protocol, adds a verification code, and then sends the encapsulated underlying socket data to the cockpit system through broadcasting.

[0007] Further, the model information is encapsulated at the same time.

[0008] Further, in step S2, the data receiving module of the cockpit system listens to the broadcast signal in real time. After receiving the data, the data is first verified for format, and after confirming that the data format is correct, a preset data analysis algorithm is used to analyze the data.

[0009] Further, in step S3, the data recognition module identifies and classifies each data block in the data stream according to the extracted identifier information, and determines the data type and attribute of each data block.

[0010] Further, in step S4, the cockpit system pre-establishes a mapping relationship database between the identifier and the reconstructed picture display area; the data display module queries the mapping relationship database according to the classification result of the data recognition module to determine the display area corresponding to each data block; then the data block content is reconstructed and displayed to the specified area of the LAD, UFCP, CFD, and control table picture according to the corresponding display rules and format, thereby realizing the intuitive and accurate display of the flight task data on the cockpit instrument.

[0011] Further, in step S4, the cockpit system pre-establishes a mapping relationship database between the identifier and the reconstructed picture display area; the data display module queries the mapping relationship database according to the classification result of the data recognition module to determine the display area corresponding to each data block; then the data block content is reconstructed and displayed to the specified area of the LAD, UFCP, CFD, and control table picture according to the corresponding display rules and format, thereby realizing the intuitive and accurate display of the flight task data on the cockpit instrument.

[0012] Further, in step S4, the mapping relationship database between the identifier and the reconstructed picture display area pre-established by the cockpit system is a SQLite database or a memory database, which supports dynamic addition, modification, or deletion of the mapping relationship between the identifier and the display area through a configuration file or a remote instruction.

[0013] Furthermore, the specified display rules in step S4 include: numerical data is displayed in the form of a dashboard or bar chart, text data is displayed in a fixed format text box, and status data is displayed in the form of indicator lights or color codes, and the update frequency of the displayed content is consistent with the data transmission frequency.

[0014] Furthermore, the invalid data is handled in step S2 by recording the invalid data reception time, data length, and format anomaly information to the cockpit system log, and sending the invalid data information to the flight debriefing system through the feedback channel so that the flight debriefing system can resend the corresponding data.

[0015] Technical Effects: The cockpit instrument reconstruction method for flight debriefing provided by this invention offers strong technical support for data reception and analysis. The main beneficial effects are as follows: 1) Improve data recognition accuracy This invention effectively solves the problem of data block confusion in traditional methods by setting a unique identifier for each data block and combining data parsing and identification mechanisms.

[0016] 2) Improve image reconstruction efficiency This invention utilizes a pre-established mapping relationship between identifiers and cockpit instrument display areas to quickly and accurately reconstruct and display data on a designated screen, greatly improving the efficiency of flight debriefing.

[0017] 3) Improve data transmission reliability The present invention ensures the integrity and reliability of data during transmission and processing by performing verification processing during data encapsulation and format verification before data parsing. Attached Figure Description

The described embodiments are only a part of the embodiments of this invention, not all of them; all other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort fall within the protection scope of this invention.

[0020] The present invention employs the following steps to design a cockpit instrument reconfiguration method for flight debriefing.

[0021] Step 1: The flight debriefing system collects various flight data and divides this data into different data blocks, assigning a unique identifier to each data block. Using a specific data encapsulation protocol, the identifier and the corresponding data block are encapsulated, and a verification code is added, along with the aircraft type information. Subsequently, the flight debriefing system broadcasts the encapsulated low-level socket data to the cockpit system.

[0022] Step Two: The cockpit system's data receiving module monitors the broadcast signal in real time. Upon receiving data, it first verifies the data format. After confirming the data format is correct, it uses a data parsing algorithm to parse the data. This algorithm can quickly and accurately separate identifier information, aircraft information, and the specific content of each data block, providing a foundation for subsequent data processing. Step 3: Based on the extracted identifier information, the data recognition module identifies and classifies the data blocks in the data stream one by one, clarifying the data type and attributes of each data block. Step 4: The cockpit system pre-establishes a mapping database between identifiers and reconstructed display areas. The data display module queries this database based on the classification results from the data recognition module to determine the display area corresponding to each data block. Then, the data block content is reconstructed and displayed in designated areas of the LAD, UFCP, CFD, and control panel screens according to the corresponding display rules and formats, thereby achieving a direct and accurate display of flight mission data on the cockpit instruments.

[0023] This invention effectively solves the problem of data block confusion in traditional methods by assigning unique identifiers to data blocks and combining data parsing and identification mechanisms. Utilizing a pre-established mapping relationship between identifiers and cockpit instrument display areas, data can be quickly and accurately reconstructed and displayed on designated screens, greatly improving the efficiency of flight debriefing. Simultaneously, verification processing during data encapsulation and format validation before data parsing ensure the integrity and reliability of data during transmission and processing.
