Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions according to the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic view of an aircraft according to an exemplary embodiment of the present application. Aircraft 100 may refer to an aircraft that flies in the atmosphere, primarily by virtue of static buoyancy of air or aerodynamic lift produced by relative movement with air. Aircraft 100 may include, but is not limited to, aircraft, glider, helicopter, autogyro, tiltrotor aircraft, and the like. The aircraft 100 may be an unmanned aircraft, for example, an unmanned aircraft.

The exterior of the aircraft 100 is provided with multiple sets of phased array antennas oriented in different directions and at different angles. Each group of array antennas includes one or more antennas. Each group of array antennas can independently control the signal beam direction, the signal beam direction of each group of array antennas is different, the signal beam direction of each group of array antennas comprises different angle ranges, and no overlapping part exists.

Referring to fig. 2, fig. 2 is a flow chart illustrating an aircraft communication method according to an embodiment of the application. The aircraft communication method may be applied to an aircraft or an aircraft communication device to be mentioned later. The aircraft communication method may include the following steps S110-S130.

Step S110, a current position of a communication target relative to the aircraft is acquired, where the communication target is within a preset range of the aircraft.

The communication targets may be one or more, and the communication targets may include aircraft and ground stations. Aircraft include, but are not limited to, aircraft, gliders, helicopters, autogyros, tiltrotors, and the like. The ground station can comprise a ground station which needs to be communicated with the current flight mission of the aircraft, and also can comprise a ground station which does not need to be communicated with the current flight mission of the aircraft.

In order to adapt to different aircrafts, the preset range can be determined according to the size of the aircrafts and the density of the ground stations corresponding to the flight tasks of the aircrafts, and the preset ranges of different flight tasks can be different. For example, the aircraft may read its own size and weight. The aircraft can acquire a ground station sequence of communication required by the flight mission, and the ground station density is determined according to the ground station sequence. The aircraft can determine the preset range corresponding to the flight task according to the size and the weight of the aircraft and the density of the ground station. As an example, the preset range may be a circular range centered on the aircraft with a radius of 3 kilometers.

The aircraft may obtain the current position of the aircraft via a satellite positioning system (GPS, GLONASS, beidou, galileo, etc.). Based on the current position of the aircraft, the aircraft may determine that a ground station or other aircraft within a preset range of the current position of the aircraft is the communication target. As an example, referring to fig. 3, fig. 3 is a schematic diagram of an aircraft communication scenario provided by an exemplary embodiment of the present application. Ground stations 300 and aircraft 200 within a predetermined range of aircraft 100 are communication targets.

The aircraft may obtain the current location of the communication target through a built-in database, a web query, or a Broadcast automatic correlation monitoring (ADS-B) message, among other channels.

Step S120, determining an array antenna corresponding to the current position of the communication target as a target array antenna corresponding to the communication target based on the correspondence between the position of the communication target and the array antenna, specifically: the array antenna is fixed to the aircraft fuselage with its coverage angle fixed relative to the bow direction. Therefore, the included angle between the target and the head direction is obtained according to the relative position of the communication target and the aircraft, so as to determine which group of array antennas can cover the target direction.

The corresponding relation between the position of the communication target and the array antenna can be preset and stored in the aircraft to form an array antenna mapping table; the location coordinates of a fixed communication target (typically a ground station) are pre-stored and the aircraft needs to determine which set of array antenna sectors the target direction is within based on the communication target location, its own location and heading. During flight, the aircraft position changes continuously, and thus the relative angle of the communication target changes, possibly changing from one set of antenna sectors to another. The correspondence of the locations of the communication targets to the array antennas may be a one-to-one correspondence or a many-to-one correspondence, i.e. a group of array antennas may correspond to the locations of one or more communication targets.

After the aircraft obtains the current position of the communication target, the array antenna corresponding to the current position of the communication target can be queried in the array antenna mapping table based on the current position of the communication target, and the queried array antenna is used as a target array antenna corresponding to the communication target.

As previously mentioned, the exterior of the aircraft is fitted with multiple sets of array antennas at different angles in different directions. The aircraft can acquire the signal beam directions of a plurality of groups of array antennas arranged on the aircraft, determine a plurality of angle intervals according to the signal wave speed directions of the plurality of groups of array antennas, and establish the corresponding relation between the angle intervals and the array antennas based on the corresponding relation between the signal beam directions of the plurality of groups of array antennas and the plurality of angle intervals.

As an example, the correspondence between the angle interval and the array antenna is shown in table 1. The aircraft is externally provided with three groups of array antennas, namely an organic head array antenna, an organic tail array antenna and a middle array antenna. The aircraft nose array antenna is arranged on the aircraft nose. The tail array antenna is mounted at the tail of the aircraft. The central array antenna is mounted in the middle of the aircraft. The signal beam directions of the head array antenna, the tail array antenna and the middle array antenna are different. The method comprises the steps of determining an angle range included in a signal beam direction of a head array antenna as an angle interval A, determining an angle range included in a signal beam direction of a tail array antenna as an angle interval B, determining an angle range included in a signal beam direction of a middle array antenna as an angle interval C, and forming a corresponding relation between the angle interval and the array antenna shown in table 1.

TABLE 1

Angle interval	Array antenna
		A	Machine head array antenna
B	Tail array antenna
		C	Middle array antenna

The aircraft may determine the angular interval in which the current position of the communication target is located. And determining the array antenna corresponding to the angle interval where the communication target is located as a target array antenna corresponding to the communication target based on the corresponding relation between the angle interval and the array antenna. As an example, as shown in fig. 3, the angle interval in which the current position of the aircraft 200 is located is the angle interval a. The angular interval in which the current position of the ground station 300 is located is the angular interval C. Based on the correspondence between the angle interval and the array antenna shown in table 1, it may be determined that the target array antenna corresponding to the aircraft 200 is the head array antenna of the aircraft 100, and the target array antenna corresponding to the ground station 300 is the middle array antenna of the aircraft 100.

Step S130, communicating with the communication target based on the target array antenna corresponding to the communication target.

The aircraft may determine the device type of the communication target, which may include, but is not limited to, aircraft and ground stations. The aircraft may adjust the beam parameters of the target array antenna according to the device type, resulting in adjusted beam parameters, which may include, but are not limited to, signal beam direction and signal beam intensity. The aircraft may communicate with the communication target based on a target array antenna corresponding to the communication target using the adjusted beam parameters. The beam parameters are adjusted according to the equipment types of the communication targets, and the adjusted beam parameters are adopted for communication, so that the connection requirements of different communication targets can be met, and the success rate and the efficiency of communication connection are improved.

After the aircraft determines the target array antennas corresponding to the communication targets, the aircraft can further determine the number of the communication targets in each angle interval, and communicate with the communication targets according to the number of the communication targets in each angle interval and the target array antennas corresponding to the communication targets.

If only one communication target exists in the same angle interval, the aircraft can directly communicate with the communication target based on the target array antenna corresponding to the communication target. Specifically, the aircraft may communicate with the communication target based on the target array antenna corresponding to the communication target using the beam parameters adjusted based on the communication target. As an example, as shown in fig. 3 and table 1, only the aircraft 200 exists in the angle interval a of the aircraft 100, the target array antenna of the aircraft 200 is the head array antenna corresponding to the angle interval a, and the aircraft 100 may communicate with the aircraft 200 through the head array antenna of the head by adopting the beam parameters adjusted based on the aircraft 200. Only ground station 300 is present in angle interval C of aircraft 100, and the target array antenna of ground station 300 is the middle array antenna corresponding to angle interval C, and aircraft 100 may communicate with ground station 300 through the middle array antenna in the middle thereof using beam parameters adjusted based on ground station 300.

If the same angle interval includes at least two communication targets, the aircraft may divide the connection order and the time slices for the at least two communication targets, where the at least two communication targets correspond to the same group of target array antennas. And communicating with the at least two communication targets based on the target array antennas, the connection sequences and the time slices corresponding to the at least two communication targets. Specifically, the aircraft may communicate with the at least two communication targets by adopting the target array antenna and the wave speed parameters adjusted based on the respective correspondence of the at least two communication targets according to the connection order and the time slice corresponding to the at least two communication targets.

The aircraft may store priorities corresponding to communication targets of different device types, e.g., ground stations are typically set to be higher than the aircraft's priority, and the aircraft co-located with the aircraft itself is higher than the aircraft co-located with the aircraft itself. The aircraft may divide the connection order and time slices for at least two communication targets according to their priority.

If the at least two communication targets are devices with the same priority, the aircraft may divide the same time slices for the at least two communication targets, and divide the connection sequence for the at least two communication targets according to the connection sequence of the at least two communication targets. As an example, referring to fig. 4, fig. 4 is a schematic diagram of an aircraft communication scenario provided by an exemplary embodiment of the present application. The aircraft 200 and 400 are two communication targets of the same angular interval (e.g., the angular interval a described above). The priority of the aircraft 200 and 400 is the same, the aircraft 400 is connected to the aircraft 100 first, and the aircraft 200 is connected to the aircraft 100 later. The aircraft 100 may place the connection sequence of the aircraft 400 before the connection sequence of the aircraft 200.

If at least two communication targets are devices with different priorities, the aircraft can divide the communication targets into time slices and connection sequences in sequence according to the order of the priorities from high to low. The time slices of the communication targets are sequentially reduced in duration along with the sequence from high priority to low priority, and the connection sequence of the communication targets is sequentially backward along with the sequence from high priority to low priority. As an example, referring to fig. 5, fig. 5 is a schematic diagram of an aircraft communication scenario provided by an exemplary embodiment of the present application. The aircraft 500 and the ground station 300 are two communication targets for the same angular interval (e.g., the angular interval C described above). The ground station 300 has a higher priority than the aircraft 500. The aircraft 100 may set the time duration of the time slices of the ground station 300 to be longer than the time duration of the time slices of the aircraft 500, e.g., the time duration of the time slices of the ground station 300 to be 500 milliseconds and the time duration of the time slices of the aircraft 500 to be 100 milliseconds. The aircraft 100 may place the connection sequence of the ground station 300 before the connection sequence of the aircraft 500.

After determining the connection sequence and the time slice of at least two communication targets existing in the same angle interval, the aircraft can communicate with at least two communication targets by adopting the wave speed parameters and the target array antennas which are correspondingly adjusted based on the at least two communication targets according to the connection sequence and the time slice corresponding to the at least two communication targets. As an example, as shown in fig. 5, the connection order of the ground station 300 precedes the connection order of the aircraft 500, the time slices of the ground station 300 have a duration of 500 milliseconds and the time slices of the aircraft have a duration of 100 milliseconds. The aircraft 100 may communicate with the ground station 300 via the central array antenna using beam parameters adjusted based on the ground station 300 for the duration of the time slice of the ground station 300. The aircraft 100 may then communicate with the aircraft 500 via the central array antenna using the beam parameters adjusted based on the aircraft 500 for the duration of the time slice of the aircraft 500. The aircraft 100 then communicates with the ground station 300 in the manner described above until the ground station 300 and/or the aircraft 500 is driven away from the angular interval C or the predetermined range of the aircraft 100.

According to the aircraft communication method provided by the embodiment of the application, through setting the corresponding relation between the communication target and the array antenna in the preset range of the aircraft, the communication connection between the aircraft and the communication target can be established based on the target array antenna corresponding to the communication target, so that the aircraft can communicate with one or more communication targets simultaneously in the preset range, the multiparty wireless communication requirements of the unmanned aircraft and other aircraft or ground stations nearby an airspace can be met, higher data bandwidth and low delay can be realized through the communication of the array antenna, and the capacity of a communication system is improved.

Referring to fig. 6, fig. 6 is a flowchart illustrating an aircraft communication method according to an embodiment of the application. The aircraft communication method may be applied to an aircraft or an aircraft communication device to be mentioned later. The aircraft communication method may include the following steps S210-S260.

In step S210, a current position of the communication target relative to the aircraft is acquired, where the communication target is within a preset range of the aircraft.

Step S220, determining an array antenna corresponding to the current position of the communication target as a target array antenna corresponding to the communication target based on the correspondence between the position of the communication target and the array antenna.

Step S230, the communication is performed with the communication target based on the target array antenna corresponding to the communication target.

The specific description of steps S210-S230 is referred to the aforementioned steps S110-S130, and will not be repeated here.

After the aircraft communicates with the communication target, the aircraft may continue to acquire the current position of the communication target relative to the aircraft, and determine whether the current position of the communication target relative to the aircraft changes according to the current position of the communication target. Specifically, it may be determined whether the current position of the communication target exceeds an angle section corresponding to a position preceding the communication target.

If the current position of the communication target does not exceed the angle interval corresponding to the previous position of the communication target, determining that the current position of the communication target relative to the aircraft is not changed, and continuing to communicate with the communication target based on the target array antenna corresponding to the communication target.

If the current position of the communication target exceeds the angle interval corresponding to the previous position of the communication target, it is determined that the current position of the communication target relative to the aircraft is detected to change, a new corresponding target array antenna can be redetermined based on the changed position of the communication target, and communication is performed with the communication target based on the new target array antenna, that is, steps S240-S260 are performed.

In particular, if the current position of the communication target cannot be acquired, it is determined that the communication target leaves the preset range of the aircraft, and at this time, communication with the communication target leaving the preset range of the aircraft may no longer be performed, that is, the signal beam may no longer be transmitted to the communication target. If the angle interval corresponding to the communication target within the preset range includes a plurality of communication targets, the aircraft may re-determine the current communication target number of the angle interval, and communicate with the communication target according to the current communication target number of the angle interval and the target array antenna, and how to determine the communication target number of the angle interval is shown in the relevant part of the step S130 and will not be described herein again.

In step S240, if a change in the current position of the communication target with respect to the aircraft is detected, the position of the communication target after the change is acquired.

As described above, the aircraft may obtain the location of the changed communication target through a built-in database, a network query, or an ADS-B message.

Step S250, determining the array antenna corresponding to the position after the change of the communication target as a new target array antenna corresponding to the communication target based on the correspondence between the position of the communication target and the array antenna.

The specific embodiment of step S250 is similar to that of step S120, referring to step S120, the only difference is that step S250 determines that the array antenna corresponding to the position after the change of the communication target is the new target array antenna corresponding to the communication target, and step S120 determines that the array antenna corresponding to the current position of the communication target is the target array antenna corresponding to the communication target.

Step S260, the communication is performed with the communication target based on the new target array antenna corresponding to the communication target.

The specific embodiment of step S260 is similar to step S130, referring to step S130, the only difference is that step S260 is based on the new target array antenna corresponding to the communication target to communicate with the communication target, and step S130 is based on the target array antenna corresponding to the communication target to communicate with the communication target.

In addition to the technical effects of the aircraft communication method provided by the embodiment of fig. 6, the method provided by the embodiment of the application can also be used for judging whether the current position of the communication target relative to the aircraft changes in real time, and adjusting the target array antenna corresponding to the communication target in real time so as to ensure that the communication target is tracked in real time to communicate with the communication target, and avoid disconnection of the communication link between the communication target and the aircraft, thereby improving the stability and instantaneity of the aircraft communication.

Referring to fig. 7, fig. 7 is a flowchart illustrating an aircraft communication method according to an embodiment of the application. The aircraft communication method may be applied to an aircraft or an aircraft communication device to be mentioned later. The aircraft communication method may include the following steps S310-S360.

Step S310, a ground station sequence corresponding to the current flight task is obtained.

The ground station sequences corresponding to the flight tasks comprise ground stations which need to be communicated with the flight tasks, and the different flight tasks correspond to different ground station sequences. The aircraft can read the ground station sequence corresponding to the flight task from the built-in database, and also can read the ground station sequence corresponding to the flight task issued by the aviation bureau from the cloud.

In step S320, the current position of the communication target relative to the aircraft is acquired, where the communication target is within a preset range of the aircraft.

Step S330, determining an array antenna corresponding to the current position of the communication target as a target array antenna corresponding to the communication target based on the correspondence between the position of the communication target and the array antenna.

Step S340, the communication is performed with the communication target based on the target array antenna corresponding to the communication target.

The specific description of steps S320-S340 is referred to the aforementioned steps S110-S130, and will not be repeated here. When the communication target is a ground station, the aircraft may also perform ground control communication with the ground station based on a target array antenna corresponding to the ground station.

In step S350, when the aircraft arrives at the interface area between (any) two adjacent ground stations in the ground station sequence, a permission request is sent to the next ground station.

The grant request is a request to request ground policing communications from a ground station. The interface area is within the preset range, when the aircraft reaches the interface area between two adjacent ground stations in the ground station sequence, the two adjacent ground stations belong to the communication target, at this time, the aircraft can communicate with the two adjacent ground stations at the same time, the aircraft performs ground control communication with the previous ground station in the two adjacent ground stations, and does not perform ground control communication with the next ground station. For ground station handoff, the aircraft may send a grant request to the next ground station based on the target array antenna to which the next ground station corresponds.

Step S360, when a positive response of the permission request sent by the next ground station is received, the ground control communication connection with the previous ground station is disconnected.

When the aircraft receives a positive response of the permission request sent by the next ground station, the ground station agrees to perform ground control communication with the aircraft, and at the moment, the aircraft can disconnect the ground control communication connection with the previous ground station, so that the aircraft can be ensured to simultaneously establish ground control communication with only one ground station in the same control area, and the area control regulation regulated by the aviation bureau is met.

In addition to the technical effects of the aircraft communication method shown in fig. 2, the aircraft communication method according to the embodiment of the application shown in fig. 7 can automatically complete the ground control communication switching of two ground stations connected in the junction area of two adjacent ground stations, so as to ensure the reliability of wireless communication connection. And because the aircraft provided by the embodiment of the application can carry out multi-party communication, when the aircraft is connected with a plurality of ground stations, the ground control communication switching between any two adjacent ground stations in the plurality of ground stations can be simultaneously and automatically realized, and the efficiency and the reliability of the aircraft for switching the ground control communication are improved.

To facilitate an understanding of ground-policing communication handoff for an aircraft implementing a ground station, an exemplary embodiment is provided herein, referring to fig. 8, fig. 8 is a schematic diagram of an aircraft communication scenario provided by an exemplary embodiment of the present application. When the aircraft 100 is in position 1, the ground station 700 is within a predetermined range of the aircraft 100, at which time the aircraft 100 is in ground-control communication with the ground station 700 via the mid-array antenna.

When the aircraft 100 arrives at location 2 in the interface region between the ground station 700 and the ground station 800, the aircraft 100 communicates with the ground station 700 via the tail array antenna and communicates with the ground 2 via the head array antenna, at which point the aircraft 100 may send a permission request with the ground station 800 via the head array antenna in order to establish ground-policing communication with the ground station 800.

When aircraft 100 arrives at location 3 in the interface region between ground station 700 and ground station 800, aircraft 100 receives a positive response from ground station 800 regarding the permission request via the middle array antenna, at which point aircraft 100 may establish ground-policing communication with ground station 800 via the middle array antenna and disconnect ground-policing communication with ground station 700. After the ground policing communication between aircraft 100 and ground station 700 is disconnected, handoff of ground station 700 to ground station 800 is completed.

It should be appreciated by those skilled in the art that, although fig. 8 only shows ground control communication switching between two ground stations, in practical application, because the aircraft provided by the embodiment of the application can perform multi-party communication, when the aircraft is connected with a plurality of ground stations at the same time, ground control communication switching between any two adjacent ground stations in the plurality of ground stations can be automatically realized at the same time, so that the efficiency and reliability of switching ground control communication of the aircraft are improved.
