Description

Background Art

[0002] As an important aerial platform, drones play an important role in military reconnaissance, environmental monitoring, disaster relief and other fields. However, traditional drone control link systems often have problems such as communication delays, data loss, and unstable control, which limit the application scope and performance of drones. Traditional drone control link systems face problems such as communication delays, data loss, and unstable control, mainly including:

[0003] 1. Communication Delay

[0004] Traditional drone control links mostly use wireless communications, such as the 2.4GHz, 5.8GHz and other frequency bands. The signals in these frequency bands are susceptible to interference and attenuation, which affects the communication speed.

[0005] The processing speed of each node in the link (such as remote control, receiver, flight control, etc.) and the efficiency of the transmission protocol will also affect the communication delay.

[0006] Communication delays will increase the drone’s reaction time and reduce flight safety and stability.

[0007] In application scenarios that require real-time data transmission and control, communication delays may lead to operational errors or mission failures.

[0008] 2. Data Loss

[0009] Signal interference, attenuation and obstruction in wireless communications may result in the loss of data frames.

[0010] Equipment failure or software errors in the link can also cause data loss.

[0011] Data loss may cause the drone to be unable to receive complete control instructions, thus affecting the flight status and mission execution.

[0012] During the data transmission process, data loss may also cause incomplete or erroneous data, resulting in the ground station being unable to accurately determine the location and status of the drone.

[0013] 3. Unstable control

[0014] Communication delays and data loss are the main factors leading to unstable control.

[0015] The drone's sensor accuracy, the stability of the flight control algorithm, and the performance of actuators such as motors will also affect control stability.

[0016] Unstable control can cause the drone's flight attitude to be unstable, or even cause a crash.

[0017] In application scenarios that require high-precision control and stable flight, unstable control will seriously affect the performance and mission completion of the UAV. Summary of the invention

[0054] The communication link module is a multi-link redundant communication link module;

[0055] The ground station control module is used to generate control instructions and send them to the UAV end control module through the communication link module;

[0056] The UAV control module is used to receive control instructions from the ground station control module and control the flight and mission execution of the UAV.

[0058] In a specific implementation scheme, the communication link module includes a main link unit and a backup link unit, wherein:

[0059] The main link unit is electrically connected to the drone end control module and the ground station control module respectively;

[0060] The backup link unit is electrically connected to the UAV end control module and the ground station control module respectively.

[0061] In a specific implementation scheme, the main link unit is used to:

[0062] The ground station control instructions are encoded and the encoded control instructions are modulated.

[0063] In a specific implementation scheme, the main link unit is further used for:

[0074] The working process of the main link unit is as follows:

[0075] The ground station encodes the control instructions or other data using a specific coding method so that the integrity and accuracy of the data can be maintained during the transmission process; the encoded data is modulated and converted into a signal format suitable for wireless transmission and transmitted through the antenna; the receiving device on the drone side captures the transmitted signal, demodulates it, and restores the original data information; data decoding: the decoder decodes the received data and restores the original control instructions or other data.

[0076] When the main link unit fails or fails to work properly, the backup link unit will automatically take over the data transmission task to ensure that the communication between the drone and the ground station is not interrupted. The working process of the backup link unit is as follows: when the main link unit fails, it should be able to start and take over the work quickly without affecting the normal operation of the main link unit (when the main link is normal, the backup link is usually in standby mode); the backup link unit should be compatible with the main link unit in terms of data format, communication protocol, etc. to ensure the continuity and consistency of data transmission; in order to further improve the stability and reliability of communication, the backup link unit can use a different communication frequency band, equipment or protocol from the main link unit to reduce the possibility of simultaneous failures.

[0083] Encoding the ground station control instruction by using the main link unit, and performing modulation processing on the encoded control instruction;

[0084] The standby link unit is used to take over the communication work when the main link unit fails.
