Description

Technical Field

[0001] This invention relates to the field of aircraft control technology, and in particular to an aircraft five-sided take-off and landing auxiliary system and method. Background Technology

[0002] Five-way flight is a basic takeoff and landing route, and an important skill that drones and their controllers must master. Because drones are controlled externally by a person, the requirements for distance and angle control are even higher. Currently, drone pilots often rely on visual judgment of distance and angle during five-way takeoff and landing, which is very difficult for beginners. Most drone losses during training occur during the five-way flight phase; if speed and angle are not properly controlled during takeoff and landing, damage to the aircraft upon landing is highly likely.

[0003] Currently, landing assistance can be provided through flight control or by transmitting flight parameter data from the drone to the ground. Both methods have relatively high equipment requirements and necessitate mature and reliable flight control systems. During the development and finalization of drones, flight control systems struggle to accurately assist drone pilots in completing the five-sided flight maneuver. Relying on visual observation and experience-based flight can lead to non-standard flight paths, hindering the improvement of operators' remote control proficiency and impacting data extraction and comparison during drone test flights and development. Summary of the Invention

[0004] The purpose of this invention is to utilize the UAV's own flight assistance system, without relying on flight parameters or other auxiliary systems, but solely on its own radio signals, directional transmitting antennas, and flight attitude to indicate the UAV's current location. This solution is highly versatile and can be quickly deployed on UAVs to assist in pentagonal flight. The entire system consumes minimal power during operation and has minimal impact on the original system. The UAV uses four directional antennas, along with a ground-based directional antenna and regulating motors, allowing for relatively precise control of the UAV's flight path during pentagonal flight. This invention is simple and easy to implement, requires minimal equipment, is inexpensive, and its compact structure makes it very easy to quickly implement and modify on UAVs and other aircraft.

[0005] To achieve the above objectives, according to one aspect of the present invention, a five-sided takeoff and landing assistance system for an aircraft is provided, comprising: an aircraft 100, wherein a right transmitting antenna 1 is mounted on the right wing, a nose transmitting antenna 2 is mounted on the nose, a left transmitting antenna 3 is mounted on the left wing, and a tail transmitting antenna 4 is mounted on the tail, wherein the transmission angles and orientations of the right transmitting antenna 1, the nose transmitting antenna 2, the left transmitting antenna 3, and the tail transmitting antenna 4 are fixed; and a ground receiving end 200, wherein the ground receiving end includes a receiving antenna 5 and a status indication component 6, wherein the receiving antenna 5 is used to receive signals transmitted from the right transmitting antenna 1, the nose transmitting antenna 2, the left transmitting antenna 3, and the tail transmitting antenna 4, and the status indication component 6 indicates the flight status of the aircraft 100 according to the signals.

[0006] Optionally, the right transmitting antenna 1, the head transmitting antenna 2, the left transmitting antenna 3, and the tail transmitting antenna 4 are horn antennas. The flight status of the aircraft is determined by using horn antennas positioned at four different locations on the aircraft.

[0007] Optionally, the right transmitting antenna 1 has a transmission angle of 45 to 60 degrees, the head transmitting antenna 2 has a transmission angle of 10 to 30 degrees, the left transmitting antenna 3 has a transmission angle of 45 to 60 degrees, and the tail transmitting antenna 4 has a transmission angle of 10 to 30 degrees.

[0008] Optionally, the status indication component 6 is further used to distinguish and determine whether the signal received by the receiving antenna 5 is emitted by the right transmitting antenna 1, the head transmitting antenna 2, the left transmitting antenna 3 or the tail transmitting antenna 4, and to issue a corresponding preset indication signal.

[0009] Optionally, the receiving antenna 5 is a horn antenna with a receiving angle of 30 to 50 degrees. The ground receiving terminal 200 also includes an angle adjustment component 7 for adjusting the orientation of the receiving antenna 5 according to the signal strength.

[0010] Optionally, the status indication component 6 emits light and / or sound signals to indicate the flight status of the aircraft 100.

[0011] Optionally, the head transmitting antenna 2 and the tail transmitting antenna 4 are oriented in the same direction.

[0012] Optionally, the right transmitting antenna 1 and the left transmitting antenna 3 are oriented in opposite directions.

[0013] Optionally, the frequency band of the signal is the VHF band or the UHF band.

[0014] To achieve the above objectives, according to another aspect of the present invention, a method for assisting takeoff and landing of an aircraft in five-sided flight is provided, comprising: step S01: during five-sided flight, the right transmitting antenna 1, the head transmitting antenna 2, the left transmitting antenna 3, and the tail transmitting antenna 4 transmit signals; step S02: the receiving antenna 5 receives the signals, and the status indication component 6 indicates the flight status of the aircraft 100 according to the signals.

[0022] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0023] Figure 1 This is a schematic diagram of the architecture of an aircraft five-sided flight assistance system according to an embodiment of the present invention, as shown below. Figure 1As shown, a five-sided takeoff and landing assistance system for an aircraft includes: an aircraft 100, with a right transmitting antenna 1 mounted on its right wing, a nose transmitting antenna 2 mounted on its nose, a left transmitting antenna 3 mounted on its left wing, and a tail transmitting antenna 4 mounted on its tail. The transmission angles and orientations of the right transmitting antenna 1, nose transmitting antenna 2, left transmitting antenna 3, and tail transmitting antenna 4 are fixed. A ground receiving terminal 200 includes a receiving antenna 5 and a status indication component 6. The receiving antenna 5 receives signals transmitted from the right transmitting antenna 1, nose transmitting antenna 2, left transmitting antenna 3, and tail transmitting antenna 4. The status indication component 6 indicates the flight status of the aircraft 100 based on the signals. The transmitting antennas with fixed transmission angles and orientations, together with the receiving antennas at fixed positions, form a "transmit-receive" signal feedback network. The system determines the orientation of the transmitting antennas towards the ground receiving terminal 200 based on the received signals, thereby determining the orientation of the aircraft 100 and its flight status during five-sided flight.

[0024] According to one embodiment of the present invention, the right transmitting antenna 1, the head transmitting antenna 2, the left transmitting antenna 3, and the tail transmitting antenna 4 are horn antennas. Horn antennas are simple to set up, have stable power, and relatively fixed transmission and reception angles. By using the transmitting antennas set at four different locations on the aircraft, the flight status of the aircraft can be determined.

[0025] According to one embodiment of the present invention, the transmission angle of the right transmitting antenna 1 is 45 degrees to 60 degrees, the transmission angle of the head transmitting antenna 2 is 10 degrees to 30 degrees, the transmission angle of the left transmitting antenna 3 is 45 degrees to 60 degrees, and the transmission angle of the tail transmitting antenna 4 is 10 degrees to 30 degrees. Figure 1 The dashed lines in the diagram represent the transmission angles of each transmitting antenna. The antenna transmission angles are set according to the flight trajectory; these settings prevent signal overlap between transmitting antennas.

[0026] According to one embodiment of the present invention, the status indication component 6 is further used to distinguish and determine whether the signal received by the receiving antenna 5 is emitted by the right transmitting antenna 1, the head transmitting antenna 2, the left transmitting antenna 3, or the tail transmitting antenna 4, and to emit a corresponding preset indication signal. Specifically, ID information can be set in the signal of each antenna. Regarding the identification by the receiving antenna 5, different indication limits are preset for each transmitting antenna to distinguish which transmitting antenna the received signal comes from. Since the angle and orientation of the transmitting antenna are fixed, it is possible to identify which transmitting antenna is facing the receiving end 200, thereby determining the flight status of the aircraft 100. Further, the indication component 6 can be equipped with indicator lights and speakers to emit sound and light indication signals corresponding to each transmitting antenna. When the corresponding signal is lost, the sound and light indication signals also stop.

[0027] According to one embodiment of the present invention, the receiving antenna 5 is a horn antenna with a receiving angle of 30 to 50 degrees. The ground receiving terminal 200 further includes an angle adjustment component 7 for adjusting the orientation of the receiving antenna 5 according to the signal strength. Specifically, the angle and orientation of the directional transmitting antenna mounted on the aircraft 100 are fixed. The receiving antenna 5 mounted on the ground receiving terminal 200 is connected to the angle adjustment component 7 (such as an adjustment motor), which can adjust the orientation of the receiving antenna 5. Within the angle adjustment range of the adjustment motor, the orientation of the receiving antenna 5 is always directly facing the direction of the strongest signal strength. The size of the pentagonal flight path can be changed by setting the angle of the adjustment motor. The adjustment range of the adjustment motor can be approximately 20 degrees.

[0028] According to one embodiment of the present invention, the status indication component 6 emits light signals and / or sound signals to indicate the flight status of the aircraft 100.

[0029] According to one embodiment of the present invention, the head transmitting antenna 2 and the tail transmitting antenna 4 are oriented in the same direction. Preferably, they are positioned slightly to the left of the central axis of the aircraft 100, that is, when the aircraft 100 flies counterclockwise relative to the ground receiving terminal 200 to the second side, the ground receiving terminal 200 can receive the signal from the tail transmitting antenna 4. Figure 2-2 As shown, the signal transmitted by the receiving head transmitting antenna 2 indicates that the aircraft 100 is flying to the second side; when it flies to the fourth side, the signal transmitted by the receiving head transmitting antenna 2 indicates that the aircraft 100 is flying to the fourth side, as shown. Figure 2-4 As shown.

[0030] According to one embodiment of the present invention, the right transmitting antenna 1 and the left transmitting antenna 3 have opposite orientations. Preferably, they are symmetrically arranged on both sides of the aircraft 100. That is, when the aircraft 100 flies counterclockwise relative to the ground receiver 200 to the first and fifth sides, the ground receiver 200 can receive signals from the right transmitting antenna 1, such as... Figure 2-1 As shown, the aircraft 100 is flying to the first and fifth sides; when flying to the third side, it receives the signal transmitted by the left transmitting antenna 3, indicating that the aircraft 100 is flying to the third side, as shown. Figure 2-3 As shown.

[0031] According to one embodiment of the present invention, the signal frequency band is the VHF band or the UHF band. Furthermore, the communication distance between the UAV segment RF transmitting unit and the ground receiving end 200 in open areas is not less than 5 kilometers. The communication distance is determined by the shape of the respective transmitting and receiving antennas and the power of the transmitting segment.

[0032] A method for assisting takeoff and landing of an aircraft is provided, including: step S01: during the five-sided flight of the aircraft 100, the right transmitting antenna 1, the head transmitting antenna 2, the left transmitting antenna 3 and the tail transmitting antenna 4 transmit signals; step S02: the receiving antenna 5 receives the signals, and the status indication component 6 indicates the flight status of the aircraft 100 according to the signals.

[0033] Specifically, Figure 3 This is a detailed step diagram of a five-sided flight assistance method for an aircraft according to an embodiment of the present invention, as shown below. Figure 1 The angles and orientations of each transmitting antenna are set as shown. When the UAV flies counterclockwise in a 5-way pattern relative to the ground receiver 200, the process steps for the ground receiver 200 are as follows. Figure 3 As shown:

[0034] 1. Set the rotation angle range of the receiving antenna 5;

[0035] 2. Receive the signal from the right transmitting antenna 1;

[0036] 3. The drone takes off;

[0037] 4. The signal from right transmitting antenna 1 is lost, and the drone turns 90 degrees to the left;

[0038] 5. Receive the signal from tail transmitting antenna 4;

[0039] 6. The signal from tail transmitting antenna 4 was lost, and the drone turned 90 degrees to the left;

[0040] 7. Receive the signal from the left transmitting antenna 3;

[0041] 8. The signal from left transmitting antenna 3 is lost, and the drone turns 90 degrees to the left;

[0042] 9. Receive the signal from antenna 2 of the receiving head;

[0043] 10. The signal from head-mounted transmitting antenna 2 was lost, and the drone turned 90 degrees to the left;

[0044] 11. Receive the signal from right transmitting antenna 1;

[0045] 12. The drone lands.
