[0047] It should be understood that the specific embodiments described herein are merely intended to explain the technical solutions of the present application, and are not intended to limit the present application.

[0048] In order to better understand the technical solutions of the present application, the following will be described in detail in conjunction with the drawings and specific embodiments.

[0049] It should be noted that the execution subject of the present embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a data visualization device, etc. capable of realizing the above functions. The present embodiment and the following embodiments will be described below taking the data visualization device as an example.

[0050] The current ground station instrument panel software mainly realizes the visualization display of basic flight data. Its main mode is to obtain attitude data such as heading angle, roll angle and pitch angle through a communication interface, and to map the data into charts or numbers in a fixed layout, that is, after the hardware device transmits sensor data to the ground station, it is rendered to the interface according to the preset template.

[0051] However, the current ground station instrument panel data visualization method only displays the basic attitude parameters of the flight such as the heading angle, the roll angle and the like, cannot integrally display other key flight parameters of different types, and when performing data visualization display, different flight data are randomly arranged in the interface, so that the operator cannot quickly obtain important data, resulting in poor display effect of the current data visualization method.

[0052] Based on this, the data visualization method provided in the embodiments of the present application is provided with reference to Figure 1 , Figure 1 The flowchart of the first embodiment of the data visualization method of the present application is shown in the figure.

[0053] In the embodiment, the data visualization method comprises steps S10-S30:

[0054] Step S10, obtaining encoded flight sensor data, wherein the flight sensor data comprises flight attitude data and flight performance data, wherein the flight attitude data and the flight performance data are defined as different message types when encoding;

[0055] It should be noted that the flight sensor data is the original or preprocessed data collected and output by various sensors such as the IMU inertial measurement unit, the GPS module, the pitot tube and the altimeter on the aircraft.

[0056] The flight attitude data is data describing the orientation state of the aircraft in three-dimensional space, usually including data such as the heading angle, the pitch angle and the roll angle. The flight performance data is data reflecting the dynamic running capability of the aircraft, including data such as the airspeed, the ground speed, the vertical speed, the overload, the fuel remaining amount and the altitude, which are used to evaluate the flight efficiency and the safety boundary.

[0057] The encoded data refers to the data after the sensor data is serialized and packaged according to a specific communication protocol, which is convenient for transmission through a communication link. In the communication protocol, different categories of data are allocated with independent message IDs or data structure identifiers, so that the receiving end can distinguish and parse the corresponding data according to the type field.

[0058] It can be understood that the sensor data often adopts a unified or mixed message format when being transmitted, without explicit classification and identification of different types of data, so that the existing ground station instrument panel software only integrates the basic attitude parameters such as the heading angle and the roll angle, and cannot effectively integrate the flight performance data such as the airspeed, the ground speed and the overload.

[0059] In the embodiment, different message types are defined for the flight attitude data and the flight performance data in the encoding stage, realizing semantic separation of the data source. This enables the ground station to quickly identify the data category when receiving the data, laying a foundation for subsequent multi-dimensional data aggregation and visualization processing.

[0060] Specifically, after the ground station receives the encoded data, the embodiment can quickly judge the data category according to the message type field, avoid misanalysis, improve the accuracy of data processing, and classify data at the source of multi-dimensional data, providing a structured input basis for the unified visualization of heterogeneous data, so that the system has the ability to expand and integrate key performance parameters such as airspeed and overload. The definition method of different message types only needs to extend new message types to access when adding new sensor data types, without the need to reconstruct the data analysis logic.

[0061] Step S20, based on the message type, the flight sensor data is standardized into flight data in a unified format;

[0062] It should be noted that the flight data in a unified format is data composed of consistent data structures, unified units and fixed field naming rules after standardization processing.

[0063] It can be understood that the data formats of different sensors are not the same, making it difficult for the current ground station visualization method to integrate key performance parameters such as airspeed, ground speed, and overload, and only limited attitude information can be displayed. Therefore, the embodiment converts the originally scattered and heterogeneous flight attitude data and flight performance data into standard flight data in a unified format through standardization operation.

[0064] By uniformly converting data from different sensors with different protocol formats and physical units into consistent structures and units within the system, data heterogeneity can be eliminated, providing complete and structurally consistent source data containing attitude, speed, altitude, and overload for subsequent visualization. The unified data format after standardization can be shared by display modules, alarm modules, and storage modules in the system, avoiding repeated analysis of raw data by each module, reducing coupling, and improving the clarity and expandability of the software architecture.

[0065] Step S30, based on the data type of the flight data and the pre-set hierarchical layout mode conforming to human factors engineering, the flight data is visually displayed at the corresponding position of the visualization interface.

[0066] It should be noted that the hierarchical layout mode conforming to human factors engineering is a pre-designed interface space organization model according to human visual perception rules, cognitive load theory and operation habits. It mainly includes: visual center priority, key parameters placed in the center of the screen or the golden section area; hierarchical function area, top area for navigation information such as heading, middle area for core flight state area, and bottom area for auxiliary performance parameters; information weight grading, important data displayed with large size and high contrast, and secondary data arranged with small font size and edge.

[0067] It can be understood that in the current ground instrument station visualization mode, the spatial priority is not arranged according to the importance of the data, and the parameters are distributed in an equal weight random arrangement mode, so that the operator needs to frequently scan the interface to locate the key information, which seriously affects the monitoring efficiency and emergency response speed. The embodiment realizes the intelligentization and scientization of information layout by automatically positioning and displaying the data that needs to be visualized according to the hierarchical layout mode conforming to human factors engineering and the data type, thereby improving the display effect of flight data.

[0068] In a feasible implementation mode, the data type includes graphic correlation data and regular text data, the visualization interface includes a key visual area and a regular visual area, and the specific implementation mode of visualizing the flight data at the corresponding position of the visualization interface based on the data type of the flight data and the preset hierarchical layout mode conforming to human factors engineering can also be:

[0069] If the data type is graphic correlation data, based on the hierarchical layout mode, a first display position of the graphic correlation data in the key visual area and an associated graphic of the graphic correlation data are determined, and based on the visualization rendering mode corresponding to the data type, the graphic correlation data and the associated graphic are visualized at the first display position. If the data type is regular text data, based on the hierarchical layout mode, a second display position of the regular text data in the regular visual area is determined, and based on the visualization rendering mode corresponding to the data type, the regular text data is visualized at the second display position.

[0070] It should be noted that the graphic correlation data is a flight parameter that not only needs to be presented in numerical form, but also needs to be combined with specific graphic elements such as dials, pointers, trend curves, and color gradient backgrounds to enhance readability and intuitiveness. The regular text data is a parameter whose meaning can be clearly expressed by pure numbers or simple labels, such as battery voltage, signal strength, flight mode status, etc.

[0071] The key visual area is the interface area where the user's vision is most focused and the information priority is the highest. It is usually the center, the golden section point, or the main instrument panel coverage range, and is used to display core parameters that directly affect flight safety. The regular visual area is the edge or auxiliary information area, such as the bottom of the interface, the side bar area, etc., which is used to display non-emergency, auxiliary or status information.

[0072] The associated graphic is a pointer, arc scale, background color block, trend arrow, etc. visual elements used with graphic correlation data to improve spatial perception and trend recognition ability of data. The visualization rendering mode is the font style, graphic structure, color scheme, animation effect, etc. graphic rendering strategy defined for different types of data.

[0073] By explicitly dividing the key visual area and the general visual area, a clear information hierarchy is formed, avoiding secondary information from occupying the visual focus, and improving the information density and usability of the overall interface. Corresponding to the above-mentioned visual area division, the embodiment realizes the precise matching of information importance and display form by subdividing the data type into graphic-related data and general text data and mapping them to the key visual area and the general visual area respectively. When visualizing, complex graphic rendering is used for high-priority data and lightweight text rendering is used for low-priority data, which controls the system resource consumption while ensuring the expressive power of core functions.

[0074] In an embodiment, when the ground instrument station performs data visualization, it can dynamically adjust the content composition of the key visual area according to different task scenarios such as takeoff, cruise, and landing, improving the adaptability and flexibility of the system.

[0075] In a feasible implementation, the key visual area includes a top visual area, a middle visual area, and two side visual areas, the graphic-related data includes heading angle data, roll angle data, pitch angle data, and altitude data, and if the data type is graphic-related data, based on the hierarchical layout mode, the first display position of the graphic-related data in the key visual area is determined, and the specific implementation of the associated graphics of the graphic-related data can also be:

[0076] If the graphic-related data is heading angle data, the heading angle data is determined to be at the heading angle display position of the top visual area, and the associated graphics are determined to be vertical bar scales. If the graphic-related data is roll angle data, the roll angle data is determined to be at the roll angle display position of the middle visual area, and the associated graphics are determined to be circular dials. If the graphic-related data is pitch angle data, the pitch angle data is determined to be at the pitch angle display position of the middle visual area, and the associated graphics are determined to be horizontal bar scales. If the graphic-related data is altitude data, the altitude data is determined to be at the altitude display position of the two side visual areas, and the associated graphics are determined to be vertical column charts.

[0077] It should be noted that the top visual area is a horizontal strip area located at the top of the visualization interface, which is usually the first area that the user's eyes scan when entering the interface, and is used to display navigation and directional parameters.

[0078] The middle visual area is the central core area of the interface, is the visual focus center, is the main range of continuous monitoring of the operator, and is used to display main control parameters such as the attitude and speed of the aircraft. The two-side visual area is a longitudinal area located at the left and right edges of the interface, and is used to display parameters such as height, vertical speed, and battery power that change significantly along the time axis or need to be compared longitudinally.

[0079] The vertical bar scale is a linear scale arranged vertically, and is used to display parameters with clear direction and limited range by cooperating with a pointer or a highlight bar. The circular scale is an annular layout simulating a traditional mechanical instrument, and a central pointer rotates with the value, which conforms to the spatial intuition of human beings for angle change, and is used to display angle parameters. The horizontal bar scale is a linear scale extending horizontally, and is used to display parameters by cooperating with a left-right moving pointer or a filling bar. The vertical column chart is a graph for representing the value by a vertical bar height, and intuitively reflects the height change trend and the current value, so as to facilitate quick judgment of whether the safety boundary is approached.

[0080] It can be understood that the existing ground station instrument panel usually arranges key parameters such as the heading angle and the height together with other non-key information, does not classify the space according to the functional attributes and cognitive rules, and does not match the vision and the motion line, so that the operator needs to frequently adjust the attention focus.

[0081] In this embodiment, the heading angle is placed in the top layer and uses a vertical bar scale, the horizontal roll angle and the pitch angle are concentrated in the middle layer main visual area and use a circular scale and a horizontal bar scale respectively, the spatial perception of the real flight attitude is restored, the attitude judgment accuracy is improved, the height data is placed in the two-side visual area and displayed by a vertical column chart, the height change trend is intuitively reflected by using the longitudinal space, and the critical value is monitored. The data visualization effect after rendering in this embodiment can be referred to Figure 2 , Figure 2 The visualization includes a bar scale, a circular scale, a vertical column chart, and various parameters.

[0082] By accurately matching the graphically associated data to a specific spatial area and using a graph form conforming to physical intuition, the user can complete the monitoring of key parameters in a natural scanning order, avoid visual jumps, significantly shorten the information reading time, optimize the visual motion line, and improve the information acquisition efficiency.

[0083] In a possible implementation, the specific implementation of the visualization rendering mode based on the data type corresponding to the visualization rendering mode, and the visualization display of the graphically associated data and the associated graph in the first display position, can also be:

[0084] Based on the data type, determine the scale interval, text label interval, background text contrast and font size when visual rendering is performed, and based on the scale interval, the text label interval, the background text contrast and the font size, the first display position is used to visually display the graphic associated data and the associated graphic.

[0085] Need to be explained, the scale interval is the physical distance between the two adjacent main scale lines on the scale line,

[0086] The text label interval is the distance between the scale value label and the corresponding scale line, and the arrangement interval between the labels, the background text contrast is the brightness or color difference ratio between the text color and the background color, the visual rendering mode is the specific drawing strategy of converting data into graphic interface elements, and the combination configuration of all the visual parameters, different data types can use different rendering templates.

[0087] It can be understood that the visual display of the current ground instrument station lacks standardized and optimized control of rendering parameters, and mostly uses default or fixed style rendering, without differentiated design according to data importance, display area or human eye perception characteristics, resulting in problems such as too small font, dense scale, low contrast and messy labels.

[0088] The embodiment sets key visual rendering parameters based on data types, avoids pointer blocking values, label overlapping and other problems through reasonable scale and label intervals, improves the interpretation accuracy of continuous variables such as angle and height, uses high-contrast color schemes (such as dark background + bright text), which meets the sensitive characteristics of human eyes to light and dark differences, and prolongs the effective monitoring time. In the embodiment, the rendering operation is determined based on the mapping relationship between the data type and the rendering parameter, ensuring consistent display style in different ground station terminals and different task scenarios, and improving the operation habit transfer efficiency.

[0089] Specifically, in the embodiment, the top area accounts for 25%, and the heading angle is displayed in the center. The upper layer is a Chinese direction mark of east, northwest, northeast, etc., with a font size of 24px and a font weight of bold. The lower layer is an angle scale, with a scale line interval of 10px, and ±45° is marked in red.

[0090] The middle layer accounts for 40%, and the horizontal roll angle is displayed in the center through a circular scale disc. The pointer of the circular scale disc is a yellow pointer, and the text is marked every 30°. The pitch angle is displayed through a bar scale, and the text is marked every 10°. The font size is set to 18px and bold.

[0091] The left side occupies 17.5% of the total area, and the vertical display height is marked with a scale every 10 meters. The critical value is marked with a red triangle, and the speed increase is marked every 2 m / s. The font size is set to 20px, and the font color is set to white.

[0092] The right side displays airspeed, ground speed, and overload in a vertical arrangement. The font size is set to 20px, the font color is set to white, the background is set to a black background box, and the contrast is set to 5:1.

[0093] In an embodiment, the rendering mode of the visualization further includes, during the rendering process of the visualization interface, dynamically adjusting the visual feedback characteristics of the corresponding parameter graphical elements according to the dynamic change rate of the flight data, wherein when the change rate exceeds a preset threshold, a nonlinear visual enhancement mechanism of the associated graphics is triggered, including: locally magnifying the scale line area, applying motion blur effects to the pointer or filling bar, and synchronously adjusting the background lightness contrast of the parameter area, and the enhancement intensity of the visual feedback characteristics is in a segmented linear relationship with the change rate. The above rendering adjustment is only performed on the graphical associated data in the key visual area.

[0094] By introducing a nonlinear visual feedback enhancement mechanism based on data change rate, when the flight parameters (such as pitch angle, overload) change rapidly in the key visual area where the operator focuses most, the composite visual effects of scale local magnification, motion blur, and background contrast enhancement are automatically triggered, which makes the parameter mutation attract the attention of the operator through visual effects before the sound alarm is issued, significantly improving the perception sensitivity to transient dangerous states. By simulating the priority capture characteristics of the human eye for moving objects, the "visual focus traction" is formed by local magnification and blur to guide the attention to quickly locate abnormal parameters, and the segmented linear control ensures that the feedback intensity matches the change severity, avoiding excessive interference.

[0095] In an embodiment, the change rate is divided into a steady state interval, a transition interval, and a pre-alarm interval. Correspondingly, the visual feedback enhancement intensity adopts a segmented mapping strategy, and no enhancement is enabled in the steady state interval. In the transition interval, only the pointer motion blur effect is activated, and the blur length is proportional to the change rate, with a maximum of 5 consecutive frames of historical position ghost. In the pre-alarm interval, in addition to the blur, the scale area local magnification animation and background contrast enhancement are also triggered, and the magnification area is always centered on the current value and dynamically translated with the value. The local magnification animation adopts a non-uniform time easing function, and the duration is controlled within a preset time threshold to ensure visual highlighting but not interfere with continuous reading.

[0096] By dividing the parameter change rate into three intervals of steady state, transition and warning preamble, the control ensures that the feedback intensity matches the change severity, avoiding excessive interference, and by using non-uniform local magnification animation and dynamic window translation centered on the current value, the operator can accurately read the real-time value while the attention is effectively guided, avoiding the misleading risk of traditional full-screen flashing or fixed area magnification.

[0097] In an embodiment, the dynamic window translation mechanism is enabled in the magnification state, its translation speed is positively correlated with the change rate of the current flight data, and a safety buffer is set for the window boundary. When the parameter approaches the edge of the scale display range, the window is automatically started to scroll horizontally in advance, so that the key scale is always centered in the magnified area, maintaining the consistency of the operator's spatial positioning. The graphic rendering of the magnified area uses a double-buffer rendering strategy. After completing the magnification and translation calculation in the background buffer, it is synthesized to the main interface at once to avoid screen tearing.

[0098] This embodiment makes the magnification process fast first, then stable, and then slow through the stage slow-down strategy, which quickly attracts attention and provides a stable reading window for the operator, avoiding misjudgment caused by instantaneous changes. The dynamic window translation automatically adjusts the display field according to the data change trend, combined with the safety buffer design, to ensure that even in the process of violent maneuvering, the key value and its surrounding scale are always centered in the magnified area, maintaining the operator's continuous cognition of the angle or speed spatial relationship.

[0099] As can be seen from the above, the embodiment obtains encoded flight sensor data, the flight sensor data including flight attitude data and flight performance data, the flight attitude data and the flight performance data being defined as different message types when encoding, the flight sensor data being standardized into flight data in a unified format based on the message types, and the flight data being visually displayed at corresponding positions of a visual interface based on the data types of the flight data and a preset hierarchical layout mode conforming to human factors engineering.

[0100] The current visualization method cannot integrate and display different types of other key flight parameters, and when the data is visualized, different flight data is randomly arranged in the interface, resulting in the problem of low information display efficiency of the current data visualization method. The embodiment first standardizes the flight sensor data of different flight sensor types to make it into uniform format flight data, so as to display the uniform format flight data in the visualization interface. And when the data is visualized, instead of randomly arranging the obtained data, the data is displayed in the corresponding position in the visualization interface according to the type of the data to be visualized and the hierarchical layout mode conforming to human factors engineering, so as to highlight the key data. Therefore, as a whole, the embodiment can improve the display effect of data visualization.

[0101] Based on the first embodiment of the present application, the same or similar contents as the above embodiment one can be referred to the above introduction, and will not be repeated hereinafter. On this basis, please refer to Figure 3 , the step 20 of the data visualization method further includes steps S21-S23:

[0102] Step S21, based on the message decoding mode corresponding to the message type, the flight sensor data is decoded to obtain flight decoding data with data type of structure;

[0103] It should be noted that the message type is a field used to identify the data category in the communication protocol, which is used to distinguish different types of information packets such as flight attitude data, flight performance data, flight control instructions, etc. The message decoding mode is a data parsing method adopted for a specific message type, including byte sequence processing, field offset positioning, data type conversion, checksum verification and other operation processes, different decoding logic corresponding to different message types. The flight sensor data is the original encoded data packet transmitted by the aircraft to the ground station through the wireless link, the structure is a composite data type containing multiple fields with explicit name and type, and the flight decoding data is the intermediate data form converted from the original flight data after decoding processing, which has semantic structure and its fields can be directly called by subsequent modules for data visualization.

[0104] It can be understood that the flight attitude data, flight performance data, flight control instructions and the like during flight are different types of data and cannot be integrated in the visualization interface. Therefore, the embodiment adopts special decoding logic for different message types to avoid field misplacement or type misjudgment due to protocol differences, ensure the restoration accuracy of key parameters such as attitude and speed, and improve the accuracy and flexibility of data analysis. Moreover, in the embodiment, the method of determining the decoding mode based on the message type can only register a new decoding function when a new sensor or flight platform needs to be expanded, without the need to reconstruct the main process, thereby improving the compatibility of data visualization.

[0105] In step S22, numerical precision processing and filtering operation are performed on the flight decoding data based on a preset standardization processing method to obtain standardized flight data.

[0106] It should be noted that numerical precision processing is an effective bit number truncation or rounding operation on floating point numbers, which can avoid display redundancy, improve readability, and reduce the amount of data for subsequent rendering and transmission. Filtering operation is a smoothing operation on the original data using digital signal processing technology, which can suppress high-frequency fluctuations in the data caused by sensor noise and communication jitter, and improve the stability and authenticity of data display.

[0107] It can be understood that directly visualizing high-precision floating point numbers output by the sensor will exceed the recognition ability of the human eye, causing visual interference and wasting display resources. Moreover, sensor data that has not been filtered will cause the pointer to frequently jitter and the numbers to rapidly jump, affecting the operator's judgment of the real flight state. Therefore, the embodiment removes redundant decimal places through numerical precision processing, making the data display simple and clear, in line with the principle of information moderation in human factors engineering. Through filtering operation, data fluctuations are smoothed and transient noise is eliminated, making the pointer move more smoothly and the trend change more realistic, improving visual comfort and judgment accuracy.

[0108] In a possible implementation, the specific implementation of the flight decoding data based on the preset standardization processing method, the numerical precision processing and the filtering operation, can also be:

[0109] Based on a preset decimal place processing specification, the number of decimal places of the flight decoding data is adjusted to obtain simplified flight data that retains the corresponding number of decimal places. Based on a preset filtering window, the average value of each simplified flight data in the filtering window is calculated to obtain the standardized flight data, wherein the simplified flight data in the filtering window includes the simplified flight data at the current time and the simplified flight data before the current time.

[0110] It should be noted that the simplified flight data is more concise intermediate data after decimal point truncation processing, the current time simplified flight data is the latest data value after this decoding and decimal point processing, and the simplified flight data before the current time is a plurality of previous data points processed in the history cache, and constitutes a time sequence input of a filter window.

[0111] It can be understood that the embodiment eliminates invalid precision interference by unifying the number of decimal places, arranges the interface numbers neatly and highlights the key points, so that the visualized mode of data meets the human factors engineering. And the filter window containing historical data is used for average calculation, which smoothes the instantaneous fluctuation caused by sensor noise and communication jitter, weakens the influence of single abnormal value on the display result, and improves the robustness of display. Through the above data standardization processing, the output standardized flight data has reasonable precision and good stability, thereby improving the visual effect of data on the ground instrument station.

[0112] In step S23, the standardized flight data is formatted into a unified string format, and the flight data in a unified format is obtained.

[0113] It can be understood that different parameters adopt different text expression methods, so that different types of parameters cannot be integrated and displayed in the visual interface. Therefore, the embodiment formats the standardized flight data into a unified string format, can realize the standardization of the expression form of flight data, makes various flight parameters output externally in a consistent text structure, is convenient for the visual interface to directly call and render, so as to achieve the effect of integrating and visualizing different types of data in the visual interface. At the same time, the unified string format is also suitable for other modules except data visualization, and enhances the generality and reusability of data in the system.

[0114] In an embodiment, in the process of formatting the flight data, a semantic format modifier related to the data type and the display area is also embedded, to generate an enhanced string with rendering instruction marks, wherein the semantic format modifier includes font weight identification, scale dynamic range identification and background color mapping identification.

[0115] The enhanced string is delivered to the visualization module, and the modifiers in the enhanced string are parsed by the rendering engine and dynamically applied to the corresponding visual style, and the mechanism only takes effect for the flight data that has been mapped to the key visual area and has associated graphics, and does not enable the modifier embedding for the regular text data and the parameters in the irregular visual area.

[0116] By introducing semantic format modifier in the string formatting stage of standardized data, the data semantics and visual presentation instructions are deeply integrated into the same text stream, so that the visualization module can automatically restore the high-fidelity display style without additional query configuration table or conditional judgment. Different from the inherent mode of separating logic and presentation in traditional interface development, the lightweight and extensible rendering semantic delivery is realized by using string carrier without increasing communication overhead, which significantly improves the system response efficiency and style consistency. The precise binding relationship among data type, display area and associated graphics established in the embodiment provides context support for the modifier, thereby realizing low-latency, high-precision and adaptive visualization rendering enhancement in the specific flight monitoring scene through the deep coupling of data format and visualization interface architecture.

[0117] In an embodiment, the semantic format modifier also carries scale rendering priority instructions for controlling the display density and visual weight of the scale lines in the interval. When the flight parameter enters the high-stress interval, the rendering priority of the corresponding scale interval is automatically increased, and the segment scale is highlighted in the interface in the form of bold, lengthening or highlighting, while the visual performance of the scale in the non-sensitive area is weakened, wherein the degree of bold, lengthening and highlighting is related to the data change rate. By carrying scale rendering priority instructions in the semantic format modifier, the visualization interface is realized by using string carrier without increasing communication overhead, realizing adaptive visualization rendering of different priorities, and improving the visualization effect in different scenes.

[0118] As can be seen from the above, the flight sensor data is decoded based on the message decoding mode corresponding to the message type to obtain flight decoding data with a data type of a structure, the flight decoding data is subjected to numerical precision processing and filtering operation based on a preset standardization processing method to obtain standardized flight data, and the standardized flight data is formatted into a unified string format to obtain the flight data in a unified format.

[0119] The flight sensor data is decoded based on the message type in the embodiment to realize semantic accurate restoration of the flight sensor data, and the result is organized as structured data to improve the accuracy of data analysis and system compatibility. On this basis, the numerical value is processed and filtered based on a filtering window to effectively suppress the numerical value jump caused by sensor noise and communication jitter, so that the data is more stable and smooth, and the readability is enhanced. Finally, the processed standardized flight data is formatted into a unified string format, a unified data output interface is constructed, integrated visualization of different types of data in the visualization interface is realized, and the generality and reusability of the data in the system are enhanced.
