[0002] Aircraft have developed rapidly in recent years, such as flying cars, drones and other aircraft. Among them, small civilian aircraft are generally equipped with simple communication systems, using a single operator's 5G network or point-to-point communication, and realizing communication or control operations between aircraft and ground-end equipment through the communication system.

[0003] However, for full-airspace wireless transmission, the coverage in different areas varies significantly. For example, 5G communication has good base station coverage in urban areas, but cannot cover higher airspace (such as above 200m) and some suburban areas. For example, point-to-point communication has good coverage in open environments such as airspace and suburbs, but is severely blocked by high-rise buildings in urban areas, resulting in unstable communication of existing small aircraft and unable to meet the needs of long-distance image and data transmission in the full airspace.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0058] The communication design of aircraft in related technologies has significant differences in different regions, resulting in unstable aircraft communication and an inability to meet the needs of long-distance image and data transmission in the entire airspace. This application provides a flying car communication method that can improve the stability and reliability of the flying car communication process and enhance the safety of the flying car flight.

[0059] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0060] Figure 1 This is a flow chart of a flying car communication method shown in an embodiment of the present application.

[0061] See also Figure 1 , the method comprising:

[0062] S101 , monitoring communication links of at least two different communication modes, where the at least two different communication modes include a first communication mode and a second communication mode.

[0063] In this step, by monitoring at least two communication links with different communication modes, a target communication link that meets the requirements of this application can be selected from the at least two communication links with different communication modes.

[0064] Among them, the communication link in this application refers to the communication channel between the flying car and the ground communication system. Communication links with different communication modes refer to the communication principles and / or corresponding communication equipment required to implement the communication link. For example, communication through the on-board T-BOX and communication through point-to-point communication equipment have different communication principles.

[0065] S102: When it is monitored that the quality of the communication link in the first communication mode is better than the quality of the communication link in the second communication mode, select the communication link in the first communication mode for signal transmission.

[0066] In this step, when monitoring the communication link of the first communication mode and the communication link of the second communication mode, the communication link of the first communication mode with better communication link quality is selected for signal transmission through comparison.

[0067] The quality of the communication link can be compared with a preset parameter value, and the communication link with the better comparison result can be selected for signal transmission. For example, the communication link with the better quality can be the communication link with the strongest communication signal, the communication link with the most stable communication signal, or the communication link with the best overall communication performance evaluation.

[0068] It can be seen from this embodiment that the present application scheme monitors the communication links by setting at least two communication links with different communication modes, selects the communication link with better quality for signal transmission, effectively improves the stability and reliability of the flying car's communication in the airspace, and improves the safety of the flying car during aviation flight. In addition, at least two communication links with different communication modes can achieve mutual independence between the communication links, thereby realizing redundant backup of the flying car's communication system, avoiding the impact of failure or interference of a single communication link on the normal operation of the communication system.

[0069] Figure 2 This is a flow chart of a flying car communication method shown in another embodiment of the present application. Figure 2 The process and Figure 1 In comparison, the communication quality of the flying car is improved mainly by selecting the communication link with the best quality from the communication links of different communication modes for signal transmission.

[0070] See also Figure 2 , the method comprising:

[0071] S201, monitor the communication link of the cellular mobile communication mode and the communication link of the point-to-point communication mode, wherein the communication link of the cellular mobile communication mode includes a 4G or 5G communication link, and the point-to-point communication mode includes a 1.4 GHz point-to-point communication mode.

[0072] In this step, two communication links, cellular mobile communication mode and point-to-point communication mode, are monitored. The communication principles of the two communication modes are different. The communication link of the cellular mobile communication mode includes a 4G or 5G communication link. Both the 4G communication link and the 5G communication link use base stations, the Internet, vehicle-mounted T-BOX and other communication equipment to achieve communication between the flying vehicle and the ground end. In addition, since the 4G or 5G communication network is one of the mainstream communication networks for current equipment, the existing base stations have a wide coverage, especially in urban areas. However, the 4G or 5G communication network cannot cover higher airspace (such as above 200m) and some suburban areas. Point-to-point communication modes include 1.4GHz point-to-point communication modes. Point-to-point communication links enable point-to-point communication between the flying car and the ground. Both the flying car and the ground are equipped with matching point-to-point communication equipment (e.g., radios). Communication between the two is achieved through point-to-point communication equipment with matching frequency bands. The point-to-point communication link in this application utilizes the 1.4GHz frequency band, which has a longer wavelength, fewer co-frequency devices, and excellent long-distance transmission and anti-interference capabilities. This ensures the performance of point-to-point communication between the flying car and the ground. Open environments such as airspace and the countryside offer good coverage due to the limited obstruction. However, in urban areas, communication quality can be significantly affected by obstruction caused by tall buildings. Redundancy is achieved by utilizing two different operating modes, namely 4G or 5G communication links and point-to-point communication links, making the flying car's communication system compatible with diverse environments and improving the stability of the flying car's communication process.

[0073] Among them, 4G or 5G communication links may include communication links using different operators, such as China Mobile's 4G communication link or China Telecom's 5G communication link. Of course, the communication link of the cellular mobile communication mode can also use communication links from at least two other different operators. Due to the different base station construction conditions of different operators, the airspace coverage of the communication networks of different operators in urban areas, suburbs and other environments varies greatly. The use of 4G or 5G communication links from different operators can realize signal supplementation for flying cars in the airspace of major urban areas, thereby improving the coverage of communication links during the communication process.

[0074] S202: Determine a first difference between a first communication quality parameter of a communication link in a first communication mode and a first communication quality threshold.

[0075] In this step, by subtracting the first communication quality parameter of the communication link of the first communication mode from the first communication quality threshold, wherein the first communication quality parameter is used to evaluate the quality of the communication link of the first communication mode, and the first communication quality threshold is used to define whether the first communication quality parameter is above the excellent threshold, in this way, determining the first difference can determine whether the communication link of the first communication mode is at an excellent level.

[0076] Among them, the first communication quality parameter and the first communication quality threshold are used to evaluate the quality of the communication link, and SNR (signal-to-noise ratio) or SS-SINR (synchronization signal-signal to interference plus noise ratio) can be used. Both SNR and SS-SINR are technical indicators for measuring the reliability of the communication system, among which SS-SINR also increases the impact of interference relative to SNR.

[0077] S203: Determine a second difference between a second communication quality parameter of the communication link in the second communication mode and a second communication quality threshold.

[0078] In this step, the second difference between the communication link of the second communication mode and the communication links of other communication modes is determined by the same method as step S202. For the specific process of this step, please refer to step S202 and will not be repeated here.

[0079] In this application, there is no particular order between step S202 and step S203. It can be understood that step S202 and step S203 are independent of each other and can be performed synchronously. In this way, the efficiency of quality comparison between the communication link of the first communication mode and the communication link of the second communication mode can be improved.

[0080] Step S204: Determine, based on the first difference being greater than or equal to the second difference, that the quality of the communication link in the first communication mode is better than the quality of the communication link in the second communication mode.

[0081] In this step, when it is monitored that the first difference is greater than or equal to the second difference, it is determined that the quality of the communication link in the first communication mode is better than the quality of the communication link in the second communication mode.

[0082] Step S205: Select a communication link of the first communication mode for signal transmission.

[0083] In this step, according to step 204 , a communication link of the first communication mode with better quality is selected for signal transmission.

[0084] It should be noted that the triggering of the method of the present application can be active or passive. For example, a flying car monitors communication quality in real time. When the current communication quality deteriorates to a preset condition, the method of the present application is triggered to select a communication link with better quality for signal transmission. For another example, when other communication terminals detect that the communication quality of the flying car has deteriorated to a preset condition, they send a control command to the flying car, which passively triggers the method of the present application to select a communication link with better quality for signal transmission.

[0085] Figure 3 This is a flow chart of a flying car communication method shown in another embodiment of the present application.

[0086] Please also see Figure 2 and Figure 3 In this embodiment, the method of the present application may further include, after step S203:

[0087] Step S206: Determine, based on the first difference being smaller than the second difference, that the quality of the communication link in the second communication mode is better than the quality of the communication link in the first communication mode.

[0088] This step is similar to step S204. When it is monitored that the first difference is smaller than the second difference, it is determined that the quality of the communication link in the second communication mode is better than the quality of the communication link in the first communication mode.

[0089] Step S207: Select a communication link of the second communication mode for signal transmission.

[0090] This step is similar to step S205 , and according to step 207 , a communication link of the second communication mode with better quality is selected for signal transmission.

[0091] In summary, it can be seen from this embodiment that the present application scheme, by setting up communication links in two different communication modes, namely cellular mobile communication mode and point-to-point communication mode, utilizes the characteristics that the communication links in the cellular mobile communication mode and the communication links in the point-to-point communication mode have different airspace coverage in different environments, effectively improves the coverage rate of the corresponding communication network of the flying car, effectively improves the stability of the communication environment of the flying car, and further improves the safety of the flying car during aviation flight.

[0092] Figure 4 This is a flowchart of a flying car communication method shown in an embodiment of the present application. Figure 4 The method can realize a multi-level optimization process for communication links, thereby selecting the optimal communication link for signal transmission.

[0093] See also Figure 4 , the method comprising:

[0094] S301, monitor the communication link of the cellular mobile communication mode and the communication link of the point-to-point communication mode, wherein the communication link of the cellular mobile communication mode includes at least two communication links 4G and\or 5G communication links established by different operators respectively, and the point-to-point communication mode includes a 1.4GHz point-to-point communication mode.

[0095] In this step, the communication link of the cellular mobile communication mode and the communication link of the point-to-point communication mode are monitored in real time, wherein the communication link of the cellular mobile communication mode adopts 4G and\or 5G communication links of communication links of different operators, and the point-to-point communication mode adopts 1.4GHz point-to-point communication mode.

[0096] It should be noted that the communication link in this application refers to the communication channel between the flying car and the ground-side communication system. Communication links can be divided into unidirectional communication links and bidirectional communication links. In this application, the communication link between the flying car and the ground-side communication system can be a bidirectional communication link to facilitate information exchange between the flying car and the ground. Among them, at least two communication links are independently configured, that is, no interference will occur between any two communication links, and they are designed for redundancy. For example, the communication devices constituting any two communication links are independent of each other, and a single communication link is provided by an independent communication device, achieving the independence of multiple communication links, effectively improving the stability and anti-interference performance of the flying car's communication process.

[0097] S302: Compare communication quality parameters of at least two communication links in cellular mobile communication modes.

[0098] In this step, the communication links of at least two cellular mobile communication modes are compared. For example, the cellular mobile communication mode includes a 5G communication link corresponding to operator A and a 5G communication link corresponding to operator B, and the SS-SINR sizes of the two are compared.

[0099] In this application, step S302 may further include:

[0100] When the communication quality parameters of at least two communication links of the first communication mode meet the preset conditions, the communication quality parameters of the at least two communication links of the first communication mode are compared. It can be understood that when the communication quality parameters of all communication links of the first communication mode meet the preset values, for example, the SS-SINR of all communication links of the first communication mode is greater than 11, the comparison process is performed again, so that all communication links participating in the comparison meet the preset requirements, thereby improving the adequacy of the comparison process. Of course, it is also possible to directly select the communication link whose communication quality parameter meets the preset value to enter the subsequent comparison process. For example, all communication links of the first communication mode are read, and the communication link whose communication quality parameter meets the preset value is selected, and the communication link whose communication quality parameter does not meet the preset value is screened out to prevent the faulty communication link from affecting the normal progress of the subsequent comparison process.

[0101] S303 : Determine the communication quality parameter with the larger value according to the comparison result, and determine the communication quality parameter with the larger value as the first communication quality parameter of the communication link of the first communication mode.

[0102] In this step, the communication quality parameter with a larger value is determined according to the comparison result of step 302, and the communication quality parameter with a larger value is determined as the first communication quality parameter of the communication link of the first communication mode. It can be understood that the communication link with better quality among at least two communication links of the first communication mode is selected to participate in the subsequent process steps of the method of this application.

[0103] In addition, to ensure the accuracy of the comparison results, step S303 may further include: after the comparison results are maintained for at least a set time period, determining the communication quality parameter with the larger value based on the comparison results. By detecting whether the comparison results of the communication quality parameters are maintained for a set time period, that is, detecting the stability of the comparison results, for example, if the comparison results of the communication quality parameters of at least two cellular mobile communication mode communication links maintain a significant relationship for a period greater than or equal to 6 seconds, then the process proceeds to step S304. If the comparison results maintain a significant relationship for less than 6 seconds, then the process returns to step S302 for re-comparison. In this way, the stability and accuracy of the comparison process for determining the first communication quality parameter are effectively improved.

[0104] S304: Determine a first difference between a first communication quality parameter of the communication link in the first communication mode and a first communication quality threshold.

[0105] In this step, a better target is selected from at least two communication links of the first communication mode, and then a first difference between the first communication quality parameter of the target and the first communication quality threshold is determined.

[0106] S305: Determine a second difference between a second communication quality parameter of the communication link in the second communication mode and a second communication quality threshold.

[0107] S306: Determine a communication link with better quality based on a comparison result of the first difference and the second difference.

[0108] In this step, based on the comparison result of the first difference and the second difference, it is determined whether the quality of the communication link of the first communication mode is better than the quality of the communication link of the second communication mode or the quality of the communication link of the second communication mode is better than the quality of the communication link of the first communication mode, and the communication link with better quality is selected.

[0109] S307: Select a communication link with better quality for signal transmission.

[0110] In this step, the communication link with better quality determined in step S306 is selected, and the communication link with better quality is selected for signal transmission to improve the stability of the signal transmission process.

[0111] As can be seen from this embodiment, the present application scheme sets up a multi-level optimization method to compare the communication link with the best quality from all communication links of different communication modes, and then selects the communication link with the best quality for signal transmission, thereby further improving the communication quality of the flying car and enhancing the safety of the flying car.

[0112] Corresponding to the aforementioned application function implementation method embodiment, the present application also provides a flying car, a flying car communication system, a computing device, a computer-readable storage medium and corresponding embodiments.

[0113] Figure 5 Schematic diagram of the structure of a flying car shown in an embodiment of the present application.

[0114] See also Figure 5 The flying car 40 of the present application includes: a monitoring module 41 and a link selection module 42.

[0115] The monitoring module 41 is configured to monitor communication links in at least two different communication modes, where the at least two different communication modes include a first communication mode and a second communication mode.

[0116] The monitoring module 41 monitors communication links of at least two different communication modes, including monitoring the communication link of the cellular mobile communication mode and the communication link of the point-to-point communication mode, wherein the communication link of the cellular mobile communication mode includes 4G and\or 5G communication links, and the point-to-point communication mode includes a 1.4GHz point-to-point communication mode.

[0117] The link selection module 42 is configured to select the communication link of the first communication mode for signal transmission when the monitoring module 41 detects that the quality of the communication link of the first communication mode is better than the quality of the communication link of the second communication mode.

[0118] In some embodiments, the communication links monitored by the monitoring module 41 in the cellular mobile communication mode may also include 4G or 5G communication links. Both 4G and 5G communication links utilize communication equipment such as base stations, the internet, and vehicle-mounted T-BOXs to enable communication between the aircraft and the ground terminal. Furthermore, since 4G or 5G communication networks are among the mainstream communication networks currently available, existing base stations offer wide coverage, particularly in urban areas. However, 4G or 5G communication networks lack coverage in higher altitudes (e.g., above 200 meters) and some suburban areas. The 4G or 5G communication links may include communication links from different operators, such as China Mobile's 4G communication links or China Telecom's 5G communication links. Of course, the communication links in the cellular mobile communication mode may also utilize communication links from at least two other different operators. Due to differences in base station construction between different operators, the airspace coverage of their communication networks in urban and suburban environments varies significantly. Using 4G or 5G communication links from different operators can achieve signal complementation in the airspace of major urban areas, thereby improving the coverage of the communication links during communication.

[0119] In some embodiments, the monitoring module 41 is further configured to determine a first difference between a first communication quality parameter of a communication link in the first communication mode and a first communication quality threshold; and to determine a second difference between a second communication quality parameter of a communication link in the second communication mode and a second communication quality threshold. The link selection module 42 is further configured to determine that the quality of the communication link in the first communication mode is superior to the quality of the communication link in the second communication mode based on the first difference being greater than or equal to the second difference; and to select the communication link in the first communication mode for signal transmission.

[0121] See also Figure 6 The flying car communication system of the present application includes: a flying car 40 and a communication device 50.

[0122] The flying car 40 is configured to monitor at least two communication links in different communication modes, including a first communication mode and a second communication mode; and when the quality of the communication link in the first communication mode is detected to be superior to the quality of the communication link in the second communication mode, select the communication link in the first communication mode for signal transmission. The flying car 40 may be equipped with other onboard systems, such as a central controller, a flight control unit, an autopilot unit, and an audio-visual system. The central controller has a variety of interfaces and strong computing capabilities. The onboard systems transmit the required data to the central controller via an interface such as the Internet or CAN. The central controller also implements the aforementioned communication control of the flying car.

[0123] Communication device 50 is used to establish communication links in at least two different communication modes between flying car 40 and ground-based communication system 70 via antenna 60.
