Description

Technical Field

[0001] The present invention relates to the field of simulation technology, and more specifically, to a method and device for simulating meteorological radar data. Background Art

[0002] The display system of a civil aircraft can provide a meteorological radar display screen for the pilot, enabling the pilot to timely and accurately understand the meteorological conditions around the aircraft, so as to make correct flight decisions and ensure the personal safety of the passengers. Meteorological factors are important factors affecting aircraft flight and are one of the important verification function items of the aircraft display system. Verifying the impact of different meteorological data on the display system is of great significance for safe flight.

[0003] Currently, to verify the impact of different meteorological data on the display system, a method based on meteorological radar simulation is used. The implementation process is to complete the modeling of meteorological cloud clusters based on a model, form three-dimensional stereoscopic data of the meteorological cloud clusters, complete the conversion of the data to the display system, send it to the aircraft display system, and the display system conducts a display verification, that is, to determine whether the cloud clusters modeled by the foregoing simulation have the expected display effect; compare the cloud clusters displayed by the display system with the expected effect of the modeled cloud clusters, and if they are consistent, it is considered that the verification passes.

[0004] However, in the modeling of meteorological cloud clusters, the accuracy and credibility of the model have always been important difficulties in current simulations. It is difficult for the meteorological cloud cluster data based on the model to fully simulate real meteorological cloud clusters; moreover, the generation method of the display data generated based on the model itself needs to be verified and evaluated. Therefore, overall, the implementation method of meteorological cloud cluster modeling based on the model has relatively low accuracy and credibility, resulting in relatively low accuracy of the verification results of the display system. Summary of the Invention

[0005] In view of this, the present invention provides a method and device for simulating meteorological radar data to overcome the problem of low accuracy of the verification results of the display system caused by low accuracy of meteorological cloud cluster modeling in the prior art.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Figure 1 A flowchart of a weather radar data simulation method disclosed in an embodiment of the present invention, Figure 1 The method shown is applied to a flying vehicle, the flying vehicle includes a display system, and the flying vehicle may be an aircraft, including but not limited to civil aircraft, military aircraft, etc. Refer to Figure 1 As shown, the weather radar data simulation method may include:

[0048] Step 101: Collect meteorological data obtained by the airborne display weather radar during a real flight. Among them, the meteorological data includes first communication data collected through a first protocol, and the first communication data is used to characterize the state information of different weathers in the airspace.

[0049] The first protocol among them may be, but is not limited to, the ARINC708 protocol. Therefore, the first communication data may be ARINC708 data. For example, as Figure 5 The ARINC708 weather radar communication data shown.

[0050] The real flight process may be the process of an aircraft flying in the air at a high altitude. Then, the meteorological data is the meteorological data detected by the weather radar when the aircraft is flying at a high altitude. In addition to being processed and transmitted to the airborne display of the aircraft itself for display, the meteorological data will also be collected and obtained under the control of the execution subject of the weather radar data simulation method described in the embodiments of the present application. It should be noted that the airborne display of the aircraft itself is the display installed on the aircraft that has been put into use, and is not the display system that needs to be verified mentioned in the embodiments of the present application.

[0051] In the aerospace field, aircraft have different display modes for different weather conditions. For example, the presence of clouds is displayed in green, and the water vapor in the clouds is green when the water vapor density is low, pink when the water vapor density is medium, and red when the water vapor density is high. This information is used to prompt the pilot, who then decides whether it is necessary to fly around the clouds. Specifically, the display of clouds, along with other graphics displayed at the same time, is related to the current aircraft speed, the position of the aircraft and the clouds, etc. Therefore, the display system used in the aircraft needs to undergo corresponding display verification before it is officially put into use. The meteorological data collected and obtained above can be used to verify the basic data of the display system later.

[0052] Step 102: Acquire a real radar image corresponding to the meteorological data displayed on an onboard display during a real flight.

[0053] The real radar image is the image displayed on the recording display after the above-mentioned meteorological data is processed accordingly. Figure 5 The display system shows a weather radar image. In implementation, an image acquisition device can capture the screen of the aforementioned onboard display to obtain a real radar image. The real radar image captured here is used as a standard for subsequent verification of the display system's display image.

[0054] It should be noted that, in actual applications, the collected meteorological data and real radar images can be stored as needed. The embodiments of the present application do not impose fixed restrictions on whether the collected data is stored and how it is stored.

[0055] Step 103: loading the first communication data into a simulation model based on the first protocol, and performing simulation processing on the first communication data using the simulation model to obtain real-time first communication data.

[0056] After obtaining the meteorological data, the corresponding simulation equipment can be used to play back the meteorological data to obtain meteorological display data, that is, the real-time first communication data. Figure 5 The ARINC 708 data indicated by the arrow is shown from the real-time simulation model. Since the meteorological data obtained by the weather radar during the actual flight is directly used, the ultimately simulated meteorological targets can also most realistically restore the meteorological targets existing in the actual flight scene. Compared to existing meteorological targets obtained through model solution, such as weather clouds, the meteorological targets simulated by this application based on the data playback principle have higher accuracy. The specific method of simulating the first communication data will be described in detail in the following embodiments and will not be further described here.

[0057] Step 104: Use the core processor to perform data conversion based on the real-time first communication data to obtain the display screen to be verified of the display system.

[0058] Among them, the core processor is the core processor of the display system. The main function of the core processor in this application is to perform data conversion, such as converting the data of the first protocol into a second protocol different from the first protocol. For example, as Figure 5 shown, the core processing device converts ARINC708 data into ARINC661 data. It should be noted that the work content of the core processor only includes the conversion of data protocols and does not process the data content itself.

[0059] After obtaining the real-time first communication data through the simulation device, it can be processed into display data that can be displayed and output, and transmitted to the display system to drive the display system, and the display system performs display output on the display data.

[0060] Step 105: Compare the real radar screen and the display screen to be verified to obtain a first comparison result, and obtain a first verification result based on the first comparison result.

[0061] If the display effects of the real radar screen and the display screen to be verified are highly similar, it can be considered that the display screen to be verified passes the verification, that is, the display system passes the verification. In specific implementation, a similarity threshold can be preset. When the similarity between the display screen to be verified and the real radar screen exceeds the similarity threshold, it is determined that the display system passes the verification; when the similarity between the display screen to be verified and the real radar screen is lower than the similarity threshold, it is determined that the display system does not pass the verification.

[0062] The above verification process is to verify whether the display logic of the display system for different weather radars is correct by comparing the weather radar screen (display screen to be verified) of the display system with the real radar screen collected before (for example, Figure 5 as shown, the image comparison module executes Step 105).

[0063] The weather radar data simulation method described in this embodiment can, in actual application, collect the display data of the real-time weather radar of the aircraft, load the collected data into the simulation model to obtain real-time first communication data, and then obtain weather display data for output display, and output the display screen to be verified; the time characteristics of the real-time simulation of the simulation model are consistent with the airborne communication, and the airborne communication method is completely restored. By monitoring the comparison between the display screen to be verified of the display system and the display screen of the aircraft airborne display, the effectiveness of the display system can be verified at the ground stage.

[0064] The above implementation solution verifies the display screen corresponding to the meteorological display data obtained by simulating real meteorological data based on real radar images. The entire solution implementation is based on real meteorological data and real radar display images, without relying on simulated data, thereby effectively ensuring the authenticity and accuracy of the verification results.

[0065] Figure 2 The flowchart of obtaining the display screen to be verified is shown. In combination with Figure 2 as shown, the to-be-verified display screen of the display system obtained by using the core processor to perform data conversion based on the real-time first communication data may include:

[0066] Step 201: Send the real-time first communication data to the core processor by using the simulation model.

[0067] Step 202: The core processor performs data conversion on the real-time first communication data to obtain real-time second communication data, and sends the real-time second communication data to the display system. The display system determines the to-be-verified display screen based on the real-time second communication data.

[0068] In combination with Figure 5 as shown, the first protocol may be the ARINC708 protocol, and the second protocol may be the ARINC661 protocol. The ARINC708 protocol corresponds to the above real-time first communication data, and the ARINC661 protocol corresponds to the display data that can be displayed and output on the display system, that is, the real-time second communication data.

[0069] In one implementation, the meteorological data may further include second communication data collected through the second protocol, where the second communication data is used to represent the color display of different display coordinates on the airborne display.

[0070] Then the meteorological radar data simulation method may further include: comparing the real-time second communication data sent by the core processor to the display system with the collected second communication data to verify the data conversion logic of the core processor.

[0071] That is, by comparing the real-time second communication data with the second communication data, it is determined whether the core processor can accurately convert the real-time first communication data into the real-time second communication data. The second communication data is obtained by the processor corresponding to the airborne display based on the conversion of the meteorological data, and the real-time first communication data is obtained by simulating the meteorological data. If the real-time second communication data converted by the core processor is the same as the second communication data, it can be determined that the conversion logic of the core processor is the same as that of the processor corresponding to the airborne display; since the processor corresponding to the airborne display has been put into use, its data conversion logic must be accurate. If the real-time second communication data is the same as the second communication data, it indicates that the conversion logic of the core processor is correct.

[0072] In another implementation, in the meteorological radar data simulation method, after loading the first communication data into the simulation model based on the first data protocol and before using the simulation model to perform simulation processing on the first communication data to obtain real-time first communication data, it may further include: decomposing the loaded first communication data into first communication data corresponding to each frame in chronological order..

[0073] Among them, loading meteorological data can be performed based on the ARINC708 protocol. Specifically, the loaded data can be the state information of different meteorological conditions in the airspace represented by ARINC708 communication data (different colors represent different meteorological conditions). In the implementation, the loaded data can also be decomposed in chronological order to obtain the ARINC708 data of each frame after decomposition, that is, the first communication data corresponding to each frame. For example, when the airborne device collects meteorological data, it will collect data for a period of time, such as 60s, with each frame being 10ms, so there are 6000 frames. The simulation device or simulation model decomposes these data into frame-by-frame data for subsequent playback. Loading the foregoing data into the simulation device or simulation model can obtain highly restored meteorological display data.

[0074] Figure 3 The flowchart for obtaining real-time first communication data through simulation processing disclosed in the embodiments of the present invention is shown in Figure 3 As shown, the use of the simulation model to perform simulation processing on the first communication data to obtain real-time first communication data may include:

[0075] Step 301: Determine the minimum running step of the simulation model based on the collected first communication data.

[0076] In the implementation, the minimum running step of the simulation model can be confirmed according to the collected ARINC708 data.

[0077] Step 302: Collect the scanning distance of the airborne display.

[0078] Step 303: Scale the collected first communication data proportionally according to the scanning distance and the minimum running step length to obtain real-time first communication data.

[0079] In implementation, the scanning distance requirement sent by the airborne display can be obtained, and then the proportional parameter is determined, and the radar display data is scaled proportionally according to the scanning distance. The airborne display has a scanning distance. That is, what is the actual distance represented by two pixel points on the airborne display, which can be 10m, 100m, 1000m, etc.

[0080] The real-time first communication data represents the meteorological data of the first protocol, that is, the data representing meteorological targets. Subsequently, based on the obtained meteorological display data of the first protocol, real-time second communication data that can be displayed and output in the display system is obtained, and then transmitted to the display system for display. Figure 4 The flowchart of another meteorological radar data simulation method disclosed in the embodiments of the present invention is shown in Figure 4 As shown, the meteorological radar data simulation method may include:

[0081] Step 401: Collect the meteorological data obtained by the meteorological radar of the airborne display during the real flight process, where the meteorological data includes the first communication data collected through the first protocol and the second communication data collected through the second protocol, and the first communication data is used to represent the state information of different weathers in the airspace.

[0082] Based on the real flight process, the data of the ARINC708 protocol (corresponding to the first protocol) on the aircraft is collected, where the ARINC708 communication data represents the state information of different weathers in the airspace (different weathers are represented by different colors such as black, green, yellow, red, etc.).

[0083] Based on the real flight process, the data of the ARINC661 protocol (corresponding to the second protocol) on the aircraft (display data for display and output on the airborne display) can also be collected, where the ARINC661 data specifies the color display of different display coordinates on the display. The data collected by the meteorological radar includes distance data, that is, the distance between the cloud cluster and the aircraft, and data representing the water vapor density of the cloud cluster. The water vapor density of the cloud cluster is represented by different colors. Through the conversion of airborne equipment, it will be converted into the coordinates and color identification on the display.

[0084] Step 402: Collect the real radar image corresponding to the meteorological data displayed on the airborne display during the real flight process.

[0085] Step 403: Load the first communication data into the simulation model based on the first protocol, and use the simulation model to perform simulation processing on the first communication data to obtain real-time first communication data.

[0086] Step 404: Based on the real-time first communication data, use the core processor to perform data conversion to obtain the display screen to be verified of the display system.

[0087] Step 405: Simultaneously collect the display screen to be verified of the display system and the real-time second communication data sent by the core processor to the display system.

[0088] Step 406: Compare the real radar screen with the display screen to be verified to obtain a first comparison result, and compare the second communication data with the real-time second communication data to obtain a second comparison result.

[0089] Step 407: Obtain an overall verification result based on the first comparison result and the second comparison result.

[0090] The first protocol herein may be the ARINC708 protocol, and the second protocol may be the ARINC661 protocol. In this implementation, the established real-time simulation model can be used to send real-time ARINC708 data (corresponding to the real-time first communication data) to the core processor, collect the ARINC661 data (corresponding to the real-time second communication data) sent by the core processor to the display system, and collect the weather radar display screen of the display system, that is, the display screen to be verified.

[0091] Combined with Figure 5 As shown, the image comparison module compares the ARINC661 data (real-time second communication data) sent by the core processor (belonging to the display system) to the display system during the comparison test with the previously collected ARINC661 data (second communication data) to verify the data conversion logic from ARINC708 to ARINC661 of the core processor.

[0092] Regarding how to obtain the final verification result based on the first verification result and the second verification result, it can be determined according to needs for the indicators corresponding to the first verification result and the second verification result respectively, that is, the final verification result includes two indicators, and these two indicators correspond to the first verification result and the second verification result respectively.

[0093] In the weather radar data simulation method of this embodiment, the weather target simulation changes from the original digital-based simulation or signal-based simulation to the bus data-based simulation of the present invention, which can restore the real flight scenario to the greatest extent. Whether it is for the special weather training of pilots or the display verification of related equipment, it can ensure the authenticity of the verification and the consistency with the actual aircraft.

[0094] The present invention collects the meteorological radar bus communication data and the meteorological radar display screen during the flight of the aircraft, simulates the collected meteorological radar communication data based on a real-time simulator, and truly restores the meteorological radar display process during the flight. At the same time, by comparing the converted communication data of the meteorological radar, the data conversion logic of the core processor can be verified. By comparing the meteorological radar display screens, it can be verified whether the display logic of the display system is correct. The present invention can verify airborne equipment based on real bus data and display screens, and can ensure that the airborne equipment is most effectively verified before flight tests.

[0095] Based on the content described in the above embodiments, Figure 5 A real-time simulation architecture diagram of a meteorological radar based on data playback is shown. In combination with Figure 5 As shown, in an actual application, the implementation of the meteorological radar data simulation method can be completed based on a data acquisition and storage module, a data loading module, a real-time simulation module, and an image comparison module.

[0096] Among them, the data acquisition and storage module corresponds to Figure 4 Steps 401 and 402 in, and is used to collect the meteorological radar display screen of the display system of the aircraft during real flight (corresponding to the real radar screen), ARINC661 image display communication data (corresponding to the second communication data), and ARINC708 meteorological radar communication data (corresponding to the first communication data).

[0097] Among them, the data loading module and the real-time simulation module correspond to Figure 4 Step 403 in, and is used to load the first communication data into the simulation model based on the first protocol, and use the simulation model to perform simulation processing on the first communication data to obtain real-time first communication data.

[0098] Figure 5 The core processing device in corresponds to the core processor, and corresponds to step 404, and is used to perform data conversion on the real-time first communication data using the core processor to obtain the display screen to be verified by the display system.

[0099] Figure 5 The data acquisition module in corresponds to step 405, and is used to simultaneously collect the display screen to be verified by the display system and the real-time second communication data sent by the core processor to the display system.

[0100] Figure 5 The image comparison module in corresponds to step 406, and is used to compare the real radar screen with the display screen to be verified to obtain a first comparison result, and compare the second communication data with the real-time second communication data to obtain a second comparison result.

[0101] Subsequently, a verification result indicating whether the display logic of the display system and the data conversion logic of the core processor are correct can be obtained based on the first comparison result and the second comparison result.
