[0050] Optionally, the user can select the flight parameters to be decoded in the target decoding library interface, and the selected flight parameters are the target flight parameters.

[0051] Optionally, you can select the flight parameters that need to be decoded as target flight parameters in the target decoding library interface.

[0052] S140: In response to the triggering operation of the decoding control, the target flight parameter of the flight data is decoded to obtain the engineering value of the target flight parameter.

[0053] The decoding rules of the target flight parameters can be pre-stored in a target decoding library. When decoding the target flight parameters, the flight data is decoded according to the preset decoding rules to obtain the engineering values ​​of the target flight parameters.

[0054] For example, the original binary data stream recorded by data recording devices such as WDAR and WQAR can be converted into engineering values ​​with clear physical meanings and units according to the aircraft's flight parameter specification manual and related standards.

[0055] Engineering value refers to an engineering numerical value with actual physical meaning and unit; for example, converting airspeed in binary flight data into actual airspeed numerical value, the unit of airspeed numerical value can be knots or kilometers per hour, etc.

[0056] In the embodiment of the application, after obtaining the flight data, the target decoding library information corresponding to the target aircraft information is determined based on the preset correspondence between the aircraft information and the decoding library information, the target decoding library interface is displayed according to the target decoding library information, and after selecting the target flight parameter to be decoded on the target decoding library interface, the flight data is decoded by triggering the decoding control, so as to obtain the engineering value of the target flight parameter. Compared with the traditional flight data decoding mode, the application can realize accurate decoding of the target flight parameter and improve the decoding efficiency of the flight data.

[0057] Optionally, the flight data decoding method of the application can run in an electronic device. Specifically, the display interface of the electronic device includes a flight data decoding identifier, and when receiving a triggering operation on the flight data decoding identifier, a flight data decoding interface is displayed.

[0058] Please refer to Figure 2 which is a schematic diagram of the flight data decoding interface 100 of the electronic device in an embodiment of the application; the flight data decoding interface 100 includes a data collection control 110, a data viewing control 120, a fleet management control 130, and a system management control 140.

[0059] The data collection control 110 is used to obtain flight data.

[0060] The data viewing control 120 is used to display flight data.

[0061] The fleet management control 130 is used to display fleet information.

[0062] The system management control 140 is used to display a decoding library interface.

[0063] The user can obtain flight data from the data recording device of the aircraft by triggering the data collection control 110.

[0064] Alternatively, the flight data can also be pre-stored in a data processing system (QAR / DAR FTP server) on the ground, and the flight data is obtained from the data processing system when the data collection control 110 is triggered; wherein the data processing system can obtain data from the data recording device of the aircraft in advance through physical medium extraction, wireless transmission, etc. The data processing system can download flight data from the data recording device of the aircraft based on common aircraft data bus protocols such as ARINC 429, ARINC 629, AFDX, ARINC 664, etc.

[0065] The user can view flight data by triggering the data viewing control 120. Optionally, after triggering the data viewing control 120, a flight data display interface is displayed; the flight data display interface can be used to display flight data, flight parameters or other flight data related content, which can be set according to actual application needs of the user.

[0066] The user can display fleet information by triggering the fleet management control 130.

[0067] Specifically, as shown in Figure 3 The determination of the target decoding library information corresponding to the target aircraft information includes:

[0068] S121: In response to a triggering operation of a fleet management control of a display interface, a fleet management interface is displayed; the fleet management interface includes an aircraft model determination area and an aircraft information display area; the aircraft model determination area includes a plurality of aircraft model information;

[0069] After triggering the fleet management control 130, the fleet management interface is displayed. The fleet management interface is used to display fleet information. The fleet information can include the model, number, route, type, corresponding decoding library information, etc. of the aircraft.

[0070] The aircraft information display area is used to display the number and decoding library information of the aircraft corresponding to each aircraft model.

[0071] S122: In response to a selection operation of target aircraft model information of the aircraft model determination area, the number and decoding library information of the aircraft corresponding to the target aircraft model information are displayed in the aircraft information display area.

[0072] S123: The target decoding library information corresponding to the target number is determined through the aircraft information display area.

[0073] As shown in Figure 4 It is a schematic diagram of the fleet management interface 200 in an embodiment; the fleet management interface 200 includes an aircraft model determination area 210 and a decoding library information display area 220;

[0074] The aircraft model determination area 210 includes a plurality of aircraft model information, which is used for the user to determine the aircraft model information to be displayed;

[0075] The user can select the aircraft model information to be displayed through the aircraft model determination area 210.

[0076] In an embodiment of the present application, the decoding library information may be the number of the decoding library. After the user selects the aircraft model B737-8 through the aircraft model determination area 210, the decoding library information display area 220 displays aircraft information such as the number, type, route, decoding library number, and operation controls of each aircraft of the B737-8 model. The operation controls are used to implement operations such as editing, modifying, and saving the aircraft information.

[0077] The content displayed in the decoding library information display area 220 can be used to determine that the decoding library number of the aircraft numbered B-1350 is 1024. After the decoding library number is determined, the decoding library interface of the corresponding decoding library can be displayed based on the decoding library number. The correspondence between each number and the decoding library interface of the decoding library can be pre-stored in the electronic device.

[0078] In one embodiment, after the system management control 140 is triggered, a decoding library management interface 300 is displayed, such as Figure 5 As shown, it is a decoding library management interface 300 in one embodiment; the decoding library management interface includes information such as the name, data type, number, decoding library number, data performance specification, and update time of multiple decoding libraries;

[0079] In the embodiment of the present application, the decoding library management interface 300 may further include a plurality of decoding library opening controls 310 , each of which corresponds to a decoding library.

[0080] The decoding library interface of the corresponding decoding library is displayed by triggering the decoding library opening control 310. In the embodiment of the present application, the decoding library interface is opened by triggering the decoding library opening control 310 with the decoding library number 1024.

[0081] In step S130 , the target flight parameters that need to be decoded are determined in the target decoding library interface, which may be performed by selecting the target flight parameters that need to be decoded in the target decoding library interface.

[0082] like Figure 6 , which is a schematic diagram of a decoding library interface in one embodiment. The decoding library interface includes information such as the abbreviation name, full name, description, ATA code, data type, etc. of multiple flight parameters and multiple operation controls; the operation controls are used to edit, delete, modify, and other operations on the flight parameter information.

[0083] In the embodiment of the present application, each flight parameter is provided with a selection control, and the user can select the flight parameter as the target flight parameter by checking the selection control. For example, in the embodiment of the present application, ACCLAT, ACCLONG, and ACCVERT are selected as the target flight parameters.

[0084] In step S140, the target decoding library may store the position information and decoding rules of each flight parameter. The position information is used to determine the position of the target flight parameter in the flight data, and the decoding rules are used to convert the target flight parameter in the flight data into an engineering value with practical significance.

[0085] The decoding rules may include parameter types such as BNR, BCD, DIS, resolution, sampling frequency and other characteristics, aviation protocols and flight parameter specifications. Aviation protocols may be commonly used aviation protocols such as ARINC429, 573, and 717.

[0086] When decoding the target flight parameters of the flight data, the position of the target flight parameters in the data frame is identified according to the position information of the target flight parameters, and the engineering value of the target flight parameters is calculated according to the parameter type and characteristics set in the decoding rules to realize the decoding of the flight data.

[0087] The engineering values ​​of the flight parameters obtained after decoding can be stored according to a set format. For example, in this application, the decoded data is stored as an Excel table.

[0088] like Figure 7 As shown, in one embodiment, the method further includes:

[0089] S210: Determine whether there is data missing or data anomaly in the engineering value of the target flight parameter;

[0090] During the flight data collection process, data loss may occur, such as data bit loss, sign bit loss, frame loss, etc. Alternatively, during the flight data collection process, problems with the sensor may cause the sampled values ​​to be out of range.

[0091] When determining whether there is missing data in the engineering value of the target flight parameter, existing data processing software such as SPSS and SAS can be used, or existing data processing functions such as the isnull function that can identify missing data can be used to detect missing data.

[0092] When determining whether there are data anomalies in the engineering values ​​of the target flight parameters, the engineering values ​​can be visualized by drawing box plots, scatter plots, and histograms to determine abnormal data points; or, statistical methods such as the standard deviation method and the IQR method (interquartile range method) can be used to determine abnormal data points; or, clustering methods such as the K-means clustering algorithm can be used to detect abnormal data points.

[0093] S220: If there is missing data or data anomaly, fitting the missing or abnormal data points based on a preset data fitting model, and using the fitted engineering value as the engineering value of the missing or abnormal data point.

[0094] Optionally, the data fitting model can obtain the fitted engineering value by using existing filling algorithms such as forward filling, mean filling, backward filling, or the data fitting model can obtain the fitted engineering value based on existing fitting algorithms such as linear fitting, polynomial fitting, exponential fitting, logarithmic fitting, power function fitting, piecewise fitting, etc. Alternatively, the data fitting model can obtain the fitted engineering value based on machine learning algorithms such as support vector machine (SVM) and neural network.

[0095] In the embodiments of the present application, by detecting whether the decoded data has abnormalities and missing, the missing or abnormal data points are fitted based on the preset data fitting model, so as to guarantee the integrity and rationality of the decoded data, exclude abnormal data caused by data recording errors, transmission errors or decoding algorithm errors, and ensure the quality of the decoded data.

[0096] After obtaining the engineering value of the target flight parameter, it can be stored in the preset business database, so that when data analysis and application are performed subsequently, the data can be obtained from the business database for analysis.

[0097] In one embodiment, various alarm events can be constructed and triggered according to preset rules and logic, and the alarm events can be used to monitor the flight operation, performance and safety of the aircraft, so as to timely perform risk warning during the flight of the aircraft and improve the safety of the flight of the aircraft.

[0098] In one embodiment, the method further comprises:

[0099] Based on the triggering condition of the preset alarm event, it is determined whether the target flight parameter meets the triggering condition of the alarm event, and when the triggering condition is met, alarm information is generated.

[0100] The triggering condition is used to trigger the alarm event, so as to generate the alarm information to prompt the user that the aircraft has an abnormality. The triggering condition can include the number of triggering times, the triggering interval, the threshold value, etc.

[0101] Optionally, the determination that the target flight parameter meets the triggering condition of the alarm event can be that the target flight parameter exceeds the preset flight parameter threshold range. Alternatively, the number of times that the target flight parameter exceeds the preset flight parameter threshold range within the target time is greater than the target number of times, etc.

[0102] Alarm events with different alarm levels can be set up to meet different alarm requirements. For alarm events with different alarm levels, corresponding alarm methods can be set. The higher the alarm level, the more stringent the triggering conditions, and the more alarm methods are available. For example, for alarm events with lower alarm levels, the alarm information is only displayed on the local terminal device. For alarm events with higher alarm levels, the alarm information is not only displayed on the local terminal device, but can also be sent to a designated terminal (such as the terminal where the administrator is located) via the network or other wireless communication technologies, allowing for timely handling of serious alarm events.

[0103] In another embodiment, the alarm event may also be a combination of multiple alarm events, for example, an alarm event formed by combining two or more alarm events, and the alarm event formed by the combination has a higher alarm level.

[0104] After an alarm is generated, it can be sent to the corresponding terminal to alert users associated with the alarm event of an abnormal risk. The alarm can be sent to the corresponding terminal via SMS or email. The terminal can be the terminal where the person associated with the alarm event is located, including mobile phones, tablet computers, and other terminals.

[0105] In an embodiment of the present application, by determining whether the target flight parameters meet the triggering conditions of the alarm event, when the triggering conditions are met, an alarm message is generated to prompt the user that there is an abnormality, thereby realizing the monitoring of the aircraft operation status, facilitating relevant personnel to handle the alarm event in a timely manner, and improving the safety of aircraft operation.

[0106] In one embodiment, the method further comprises:

[0107] Generate a data interface; the data interface is used to send the engineering value of the target flight parameter to the third-party program when receiving a data acquisition request from the third-party program.

[0108] The data interface can be used to interact with third-party programs to meet different application needs of users.

[0109] The third-party program may be an existing data application program, such as Tableau, Power BI or other existing data analysis programs, which can achieve in-depth mining, analysis and report generation of flight data.

[0110] Alternatively, the third-party program may also be a visualization program, which is used to visualize the decoded data, thereby facilitating the display of the decoded data.

[0111] Alternatively, the third-party program can also be used for the airline's existing operations management system, which obtains the decoded data through a data interface, and thus implements operational management such as aircraft safety assessment and performance optimization based on the decoded data, thereby improving the safety of aircraft operations.

[0112] Third-party programs can obtain the decoded engineering values ​​of flight parameters through the data interface to achieve in-depth analysis, report generation, visualization and other applications of the engineering values ​​of flight parameters.

[0113] By providing an open data interface, users can access the decoded data through third-party programs, making it easier to use third-party programs to analyze and visualize the data, meeting users' different application needs.

[0114] The flight data decoding method of the present application is compatible with the data recording devices and data bus protocols of various aircraft, can quickly complete the decoding of large-scale flight data, fill in and correct abnormal and missing data in the flight data, and improve the accuracy and reliability of the decoded data; it can access a variety of third-party software through an open data interface to meet the usage needs of different users and has strong scalability; at the same time, by utilizing alarm events to monitor various flight parameters of the aircraft, it can timely discover and warn of potential risks of the aircraft and improve flight safety.
