Description

Technical Field

[0001] The present invention relates to the field of avionics monitoring technology, and more particularly to a weather display method and system based on Automatic Dependent Surveillance-Broadcast (ADS-B) data. Background Art

[0002] Currently, aircraft mainly use airborne weather radar to obtain weather information in front of the aircraft. Airborne weather radars with larger size and power can usually obtain better weather information. However, due to the limitations of aircraft installation space and power supply capacity, airborne weather radars can only detect weather information in the range in front of the aircraft. Weather information on the rest of the route can only be detected when flying in front of the weather. Since the weather is detected too late, the aircraft may not be able to avoid the weather area in time, which will affect flight safety and comfort.

[0003] In the prior art, airborne weather radars can be used to transmit electromagnetic waves and receive reflected echoes from water vapor condensation in the atmosphere, thereby detecting the spatial location of the weather area, precipitation intensity, raindrop distribution and other information, and finally indicating the rainfall in the area through different colors on the display. Due to the limitations of aircraft installation space and power supply capacity, current airborne weather radars can only detect weather information within a certain range in front of the aircraft, and cannot effectively detect weather information on the rest of the route. In addition, since the electromagnetic wave echo will gradually weaken with increasing distance, the accuracy of distant weather information may decrease.

[0004] Therefore, it is urgent to propose an accurate weather display method that can significantly improve the aircraft's ability to obtain weather information, thereby improving flight safety and comfort. Summary of the invention

[0025] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to provide a thorough understanding of the described exemplary embodiments. However, it is obvious to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other exemplary embodiments, well-known structures or processing steps are not described in detail to avoid unnecessarily obscuring the concepts of the present disclosure.

[0026] In this specification, unless otherwise specified, the term "A or B" used throughout the specification refers to "A and B" and "A or B" rather than meaning that A and B are exclusive.

[0027] In the prior art, airborne weather radars can be used to transmit electromagnetic waves and receive reflected echoes from water vapor condensation in the atmosphere, thereby detecting the spatial position of the meteorological area, precipitation intensity, raindrop distribution and other information, and finally indicating the rainfall in the area through different colors on the display. Due to the limitations of aircraft installation space and power supply capacity, current airborne weather radars can only detect weather information within a certain range in front of the aircraft, and cannot effectively detect weather information on the rest of the route. In addition, since electromagnetic wave echoes gradually weaken with increasing distance, the accuracy of distant weather information may decrease. Therefore, it is urgent to propose an accurate weather display method that can significantly improve the aircraft's ability to obtain weather information, thereby improving flight safety and comfort. The present invention receives and parses the meteorological airspace wind field, special meteorological and location data information provided in the ADS-B message to obtain airspace conditions that cannot be detected by airborne weather radar on the route, and fuses the relevant data with the airborne weather radar screen through a display, as shown below. Figure 1-3 The weather display method based on Automatic Dependent Surveillance - Broadcast (ADS-B) data is explained in detail.

[0028] Figure 1 An example of a weather display architecture diagram 100 based on ADS-B data according to an embodiment of the present invention is illustrated.

[0029] In the embodiments of the present application, the ADS-B system is also called the Automatic Dependent Surveillance-Broadcast system, which is a monitoring technology based on the global satellite positioning system and the use of air-to-ground and air-to-air data links to achieve traffic monitoring and information transmission. ADS-BOUT is the transmitting part, and the transmitter sends various information of the aircraft at a certain period. The meteorological airspace wind field information used in the present invention includes wind direction, wind speed, turbulence and wind shear; meteorological airspace precipitation information includes water vapor, cloud thickness, visibility; meteorological airspace special meteorological information includes icing, lightning, and wind shear; meteorological airspace position information includes the position of the sending device, the direction and attitude of the sending data aircraft, and real-time data can be obtained through ADS-B.

[0030] The system architecture diagram 100 of the present invention is as follows Figure 1As shown, in an embodiment of the present application, the ADS-B message sent by one or more other aircraft may provide meteorological airspace data, for example, including meteorological airspace wind field information 110, meteorological airspace special meteorological information 120, meteorological airspace precipitation information 130 and meteorological airspace position data 140. Preferably, the first period (e.g., 1 millisecond ms, etc.) of one or more other aircraft sending the ADS-B message may be smaller than the second period (e.g., 10ms or even longer) of the ADS-B message carrying the meteorological airspace data. Additionally or alternatively, the meteorological airspace data needs to be carried in the ADS-B message only when the meteorological airspace data is changed or updated. Additionally or alternatively, the sending of the ADS-B message carrying the meteorological airspace data may also be triggered when special weather occurs.

[0031] In an embodiment of the present application, an aircraft may receive and parse meteorological airspace data provided in an ADS-B message sent by one or more other aircraft, for example, including meteorological airspace wind field information 110, meteorological airspace special meteorological information 120, meteorological airspace precipitation information 130, and meteorological airspace location data 140. Preferably, the meteorological airspace wind field information 110 may provide relevant wind field information in the airspace through wind direction, wind speed, turbulence, and wind shear data in the ADS-B message. Preferably, the meteorological airspace special meteorological information 120 may provide information on whether there is icing, lightning, and wind shear threat meteorology in the airspace through threatening meteorology, icing, and wind shear data in the ADS-B message. Preferably, the meteorological airspace precipitation information 130 may provide relevant precipitation information in the airspace through water vapor, cloud thickness, and visibility in the ADS-B message. Preferably, the meteorological airspace location data 140 may provide information on the location of the meteorological airspace through the aircraft position, direction, and attitude in the ADS-B message.

[0032] In an embodiment of the present application, the ADS-B data receiving and parsing unit 115 of the aircraft receives and parses the above-mentioned ADS-B message. The ADS-B data receiving and parsing unit 115 parses the meteorological airspace data in the ADS-B message according to a standard format, and the parsed meteorological airspace data is classified and stored, and the meteorological airspace data is updated in real time according to the refresh frequency of the ADS-B message to ensure the timeliness of the meteorological data information. Preferably, the basic display page of the meteorological image of the aircraft or the radar display screen can directly display the ADS-B weather screen 170 of all ADS-B meteorological data that can be received based on the parsed meteorological airspace data. For example, when receiving an ADS-B message sent from one or more other aircraft, the ADS-B data receiving and parsing unit 115 parses the above-mentioned ADS-B message and updates the stored meteorological airspace data based on the timestamp, and updates the ADS-B weather screen 170.

[0033] In an embodiment of the present application, the data fusion processing unit 125 of the aircraft performs data fusion processing on the parsed meteorological airspace data and the meteorological radar data 150 of the aircraft detected by the airborne meteorological radar. Preferably, the data of one or more data-sending aircraft that fly over the route of the aircraft within a threshold distance or a threshold time can be selected for fusion based at least in part on the flight plan of the aircraft. For example, it can first be determined whether one or more other aircraft that send the ADS-B message are within a predetermined threshold distance or a threshold time of the route of the aircraft based on the flight plan of the aircraft and the position information of one or more other aircraft that send the ADS-B message. Preferably, the threshold distance can be a fixed value, such as 50 nautical miles, and the threshold time can be a time interval of 10 minutes or less. Preferably, the data fusion processing unit 125 performs data fusion processing on the meteorological airspace data of one or more data-sending aircraft that fly over the route of the aircraft within a threshold distance or a threshold time and the meteorological radar data 150 of the aircraft detected by the airborne meteorological radar. Preferably, the meteorological airspace data provided in the ADS-B messages sent by one or more other aircraft may have crossover or overlapping parts, and data fusion can be used to pre-process the above data. Additionally or alternatively, the meteorological airspace data provided in the ADS-B messages sent by one or more other aircraft can complement each other's meteorological data blind spots and provide airspace information with wider coverage. Preferably, the above-mentioned data fusion can be based on statistics, models, or artificial intelligence. For example, a linear regression model can be applied to integrate the meteorological airspace data with the aircraft's meteorological radar data to generate a fused data set. Additionally or alternatively, a neural network can be applied to integrate the meteorological airspace data in the ADS-B messages from different aircraft with the aircraft's meteorological radar data to generate a fused data set. Additionally or alternatively, the fused data set can also be used to predict future weather conditions on the aircraft's route.

[0034] Preferably, the data fusion processing unit 125 can confirm the weather display location through the location information. Preferably, the data fusion processing unit 115 obtains the geographical location information of the weather through the parsed latitude, longitude, altitude and direction data, for example, the distance between the weather and the aircraft can be further determined.

[0035] Preferably, the data fusion processing unit 125 can generate a first meteorological picture based on meteorological airspace data and a second meteorological picture based on the aircraft's meteorological data. For example, the degree of influence of the ADS-B meteorological picture 170 (i.e., the first meteorological picture) can be confirmed in combination with precipitation information and wind field information, so as to be reflected by color or special images, and distinguished from the aircraft's meteorological radar meteorological 160 (i.e., the second meteorological picture) by color contrast or graphic depiction. Among them, the meteorological display colors on the aircraft usually include black, green, yellow, red and crimson, which are used to indicate the intensity of different precipitation. Specifically: black represents no meteorological conditions; green represents mild meteorological conditions, such as light rain or slight precipitation; yellow represents moderate meteorological conditions, such as moderate rain; red represents severe meteorological conditions, such as heavy rain; crimson is used to indicate extreme meteorological conditions, such as heavy rain or severe precipitation. According to the thickness of the cloud layer, water vapor and visibility, the degree of precipitation can be judged, and the degree of influence of the meteorological area can be judged in combination with wind speed and direction, turbulence intensity and wind shear intensity, and the corresponding color to be displayed is determined according to its different degrees. It should be understood that the above colors are only for explanation of the present application and are not used to limit the scope of the present application.

[0036] Preferably, the data fusion processing unit 125 can determine the special weather display type through the special weather information of the weather airspace. For example, if special weather occurs, the weather area is symbolized, and different special weather can be identified with different symbols so that users can quickly identify and understand. For example, lightning is usually represented by a lightning icon or a lightning path, icing is represented by hail or small ball symbols, frost is represented by frost or ice crystal symbols, and wind shear is usually represented by stripes or arrows of different colors to represent changes in wind speed and wind direction, etc.

[0037] In an embodiment of the present application, the meteorological airspace information after parsing is displayed on a display by the meteorological picture display unit of the aircraft in combination with the meteorological information detected by the aircraft. For example, the data fusion processing unit 125 can generate an ADS-B+aircraft weather radar fusion meteorological picture 180 (i.e., a third meteorological picture) based on the data-fused meteorological data, and send it to the meteorological picture display unit for final picture display. Preferably, the aircraft's onboard processing system can also generate a more suitable future route based at least in part on the aircraft's flight plan and the data-fused meteorological data for the pilot's reference or for display on the display unit so that the pilot can make more accurate flight decisions.

[0038] In the first embodiment, the processed ADS-B weather picture 170 can be superimposed on the aircraft weather radar picture 160, and the weather picture determined by the ADS-B data can be distinguished and displayed from the airborne weather radar picture by color contrast. Figure 4 The weather picture display unit 430 described in the figure displays the final data on the liquid crystal display for the pilot to view in real time. Preferably, the first weather image can be displayed using a first color contrast, the second weather image can be displayed using a second color contrast, and both the first weather image and the second weather image can be displayed in the same layer at the same time. For example, the ADS-B weather picture 170 can be displayed using a first contrast on the basic display page of the weather image, and the aircraft weather radar picture 160 can be displayed using a second contrast.

[0039] Additionally or alternatively, in the second embodiment, the meteorological display colors and contrasts used by the first meteorological image and the second meteorological image may be the same, but the first meteorological image, the second meteorological image, and the third meteorological image may be displayed in different layers, respectively. Preferably, the first meteorological image generated based on meteorological airspace data may be displayed on the first layer, the second meteorological image generated based on the aircraft's meteorological information data may be displayed on the second layer; and the third meteorological picture generated based on the data-fused meteorological image may be displayed on the third layer. Preferably, any one of the first layer, the second layer, and the third layer may be selected for display on the basic display page of the meteorological image. Additionally or alternatively, other unselected meteorological pictures may not be displayed. For example, the ADS-B meteorological picture 170 may be displayed on the basic display page of the meteorological image, or the aircraft's meteorological radar picture 160 may be displayed, or the ADS-B+aircraft meteorological radar fusion meteorological picture 180 may be displayed.

This method can be Figure 4 The ADS-B data receiving and parsing unit in the system is used to perform the operation.

[0042] In an embodiment of the present application, method 200 includes, at 220, fusing the parsed meteorological airspace data with the own-aircraft meteorological data detected by the airborne meteorological radar.

Preferably, the method further includes: generating a first meteorological picture based on the meteorological airspace data; generating a second meteorological picture based on the local meteorological data; and generating a third meteorological picture based on the data-fused meteorological data. Preferably, generating the first meteorological picture based on the meteorological airspace data includes: determining a meteorological display position based at least in part on the meteorological airspace position information; determining a special meteorological display type based at least in part on the meteorological airspace special meteorological information; determining a meteorological display color based at least in part on the meteorological airspace precipitation information and the meteorological airspace wind field information; and generating the first meteorological picture based at least in part on the meteorological display position, the meteorological display color, and the special meteorological display type.
