Description

Technical Field

[0001] The present invention belongs to the field of unmanned aerial vehicle data link communication, and in particular relates to a method for fusion monitoring of unmanned aerial vehicle beyond-visual-range data link equipment and electronic equipment. Background Art

[0002] In traditional UAV beyond-line-of-sight data link communications, usually only a single link is used, based on a satellite communication network. This single link solution has certain risks, which may cause communication interruption of the UAV during the mission, affecting the completion of the mission. The stability and reliability of the communication link are crucial to the normal operation of the UAV. Traditional communication satellites may fail during operation, such as failed launch, orbital anomalies, system failures, etc., resulting in interruption of the communication link. In addition, satellite communications are susceptible to electromagnetic interference and natural environmental interference, such as thunderstorms, solar flares, etc., which in turn affect the stability of the communication link. Problems such as failure of ground satellite communication stations, antenna alignment deviations, and hardware equipment damage may cause communication link interruption or deterioration of communication quality. At the same time, during the flight, the UAV may encounter obstructions such as terrain and buildings, resulting in temporary interruption of the satellite communication link. The satellite communication link may also be attacked by hackers or maliciously interfered, resulting in communication interruption or leakage of sensitive information. Due to the existence of the above problems, it is particularly important to use redundant links to ensure that the UAV has a stable and reliable communication link during the mission. However, traditional redundant link solutions may have problems such as limited coverage and high costs. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a method and electronic equipment for integrating monitoring of unmanned aerial vehicle beyond-line-of-sight data link equipment, which adopts a redundant link solution based on Beidou short message RDSS to improve communication security and reliability. The specific technical solution is as follows:

[0004] A method for integrating and monitoring beyond-visual-range data link equipment of a UAV, wherein the method integrates a satellite communication main link with Beidou short message RDSS, and the specific implementation steps of the method are as follows:

[0005] S1. Set up the main satellite communication link between the UAV platform and the ground command and control station, and equip the UAV platform and the ground command and control station with Beidou short message RDSS communication terminals;

[0006] S2, the UAV flight control is powered on and enters the flight state;

[0007] S3, detecting and determining whether the satellite communication main link is disconnected;

[0008] S4, if the satellite communication main link is not disconnected, the satellite communication main link operates normally and flies according to the predetermined plan. If the satellite communication main link is disconnected, the process proceeds to step S5;

[0009] S5. Switch to the Beidou short message RDSS link as the main link, check the satellite communication main link problem, and try to reconnect;

[0010] S6, if the satellite communication main link is successfully reconnected, the satellite communication main link is switched to carry out information transmission and the flight is carried out as planned. If the satellite communication main link is not successfully reconnected, the process proceeds to step S7;

[0011] S7. Return according to the set route, and the Beidou short message RDSS link is used as the main link for real-time monitoring.

[0012] Furthermore, the Beidou short message RDSS communication terminal described in step S1 is equipped with a compatible antenna, power supply equipment and installation facilities.

[0013] Furthermore, when the satellite communication main link described in step S4 operates normally, the flight control management computer of the UAV packages the collected telemetry data and transmits it back to the ground command and control station through the satellite communication main link, while receiving the remote control signal from the ground command and control station.

[0014] Furthermore, the video management computer of the UAV transmits the payload image back to the ground command and control station via the satellite communication main link.

[0015] Furthermore, when the UAV performs a beyond-visual-range mission, the actual communication link between the UAV and the ground command and control station is achieved through the satellite communication main link.

[0016] Furthermore, when the satellite communication main link described in step S4 is disconnected, the UAV quickly switches to the Beidou short message RDSS link through the flight control management computer to maintain continuous communication.

[0017] Furthermore, the disconnection in step S3 and step S4 refers to a failure in the satellite communication main link, and information cannot be transmitted normally.

[0018] Furthermore, the Beidou short message RDSS link described in step S5 focuses on transmitting remote control and telemetry information, while suspending the transmission of image information.

[0019] Furthermore, in step S5, the ground command station uses the Beidou short message RDSS link to perform active query on the UAV platform and realize active positioning to obtain the emergency location information of the UAV.

[0020] An electronic device comprises: a memory storing executable instructions; and a processor running the executable instructions in the memory to implement the above-mentioned unmanned aerial vehicle beyond-visual-range data link equipment fusion monitoring method.

[0021] The present invention has the following beneficial effects:

[0022] The UAV beyond-visual-range data link equipment fusion monitoring method of the present invention embodies significant cost-effectiveness and performance advantages. Compared with the traditional redundant link solution, the redundant link based on Beidou short message RDSS has a wider coverage, lower cost and better real-time performance. When the main satellite communication link fails, the redundant link can be quickly put into use, thereby significantly improving the communication reliability of the UAV in a complex environment.

BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 , one Workflow diagram of a method for integrating monitoring of UAV beyond visual range data link equipment. DETAILED DESCRIPTION

[0027] Integrate the satellite communication main link with Beidou short message RDSS, set up the satellite communication main link on the UAV platform and the ground command and control station, and equip the UAV platform and the ground command and control station with Beidou short message RDSS communication terminals. Figure 1As shown, a working flow chart of the UAV beyond-visual-range data link equipment fusion monitoring method of the present invention is given. After the UAV flight control is powered on, it enters the flight state, starts the data link system, and then detects and determines whether the satellite communication main link is disconnected. If the satellite communication main link is not disconnected, the satellite communication main link operates normally and flies according to the predetermined plan. If the satellite communication main link is disconnected, it switches to the Beidou short message RDSS link as the main link, and at the same time, the problem of the satellite communication main link is checked, and an attempt is made to reconnect. If the satellite communication main link is successfully reconnected, it is transferred to the satellite communication main link for information transmission and flies according to the plan. If the satellite communication main link is unsuccessful in reconnecting, it returns according to the set route, and the Beidou short message RDSS link is used as the main link for real-time monitoring.

[0028] The method for integrating monitoring of beyond-visual-range data link equipment of unmanned aerial vehicles of the present invention proposes an advanced integrated monitoring method to enhance the communication stability and fault recovery capability of the data link equipment of unmanned aerial vehicles during beyond-visual-range flight. The method involves equipping both the unmanned aerial vehicle platform and the ground command and control station with Beidou short message communication terminals, equipped with compatible antennas and necessary power supply equipment and installation facilities. When the main satellite communication link is operating normally, the flight control management computer of the unmanned aerial vehicle will package the collected telemetry data and transmit it back to the ground command and control station through the main satellite communication link, while receiving the remote control signal from the ground command and control station. In addition, the video management computer of the unmanned aerial vehicle will also use the traditional satellite link to transmit the payload image back to the ground command and control station. When the unmanned aerial vehicle performs beyond-visual-range missions, the actual communication link between the unmanned aerial vehicle and the ground command and control station is to realize the communication between the unmanned aerial vehicle and the ground command and control station by means of the traditional satellite communication network. In the event of a failure in the main satellite communication link, the system will automatically switch to the Beidou short message RDSS link and maintain the communication connection through this backup link. In order to ensure the stability of the UAV command and control link, the UAV data link will focus on transmitting remote control and telemetry information to ensure the normal operation of the UAV, while suspending the transmission of image information. The UAV data link is a Beidou short message RDSS link. In an emergency, the ground command and control station can use the Beidou short message RDSS link to perform active inquiries on the UAV platform and achieve active positioning to obtain the emergency location information of the UAV. This fusion monitoring method has efficient fault handling and backup communication link switching capabilities, which greatly improves the communication stability and flight safety of UAVs in beyond-visual-range missions.

[0029] As a backup communication link, Beidou short message RDSS provides global coverage, excellent real-time performance and excellent anti-interference ability. When the main satellite communication link of the drone fails, the flight control management computer of the drone has the ability to quickly switch to the backup link to achieve continuous communication. At the same time, the ground command station will also switch to the Beidou short message communication link synchronously to ensure the seamless conversion of the remote control and telemetry link, thereby ensuring the continuous monitoring and control of the drone. In particular, since Beidou short message RDSS technology has a unique active positioning function compared to RNSS and GNSS, in an emergency, the ground command station can actively query the location of the drone to achieve emergency positioning. This patented technology not only greatly improves the security of communication by realizing the integration of the main satellite communication link and Beidou short message RDSS, but also significantly enhances the reliability of communication. This method of comprehensive utilization of multiple communication methods and unique positioning technology enables the drone to maintain a stable connection with the ground command station under any circumstances when performing beyond-visual-range missions, thereby enhancing the overall stability and flight safety of the drone system.

[0030] An electronic device is designed according to the above method, and the electronic device includes: a memory, wherein the memory stores executable instructions; and a processor, wherein the processor runs the executable instructions in the memory to implement the above-mentioned UAV beyond-visual-range data link equipment fusion monitoring method.

The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
