Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) control technology, and in particular to a remote control method for UAVs based on a voice gateway. Background Technology

[0002] With the continuous development of drone technology, drones are being used more and more widely in logistics, agricultural plant protection, aerial photography, and rescue missions, and automation and intelligence have become inevitable trends. However, traditional drone control methods mostly rely on dedicated remote controllers or specific ground control stations, which to some extent limits the flexibility and convenience of drone use in scenarios such as fire emergency rescue.

[0003] Walkie-talkies are common communication devices in scenarios such as fire emergency rescue. They have high transmission speed, reliable transmission technology, and strong anti-interference capabilities, and are widely used.

[0043] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0044] In the following description, when referring to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] See Figure 1 As shown, the present invention provides a remote control method for unmanned aerial vehicles (UAVs) based on a voice gateway. The method is applied to a voice gateway, which is communicatively connected to a walkie-talkie and the UAV, and includes:

[0046] S101: Receives encrypted control commands sent by a walkie-talkie, including: first, receiving the initial encrypted control command sent by the walkie-talkie; finally, filtering the initial encrypted control command to obtain the encrypted control command. Since walkie-talkies are susceptible to electromagnetic interference, background noise, and multipath effects when transmitting signals in complex environments such as fire stations, filtering the initial encrypted control command effectively removes out-of-band noise, retains the valid signal within the initial encrypted control command's frequency band, and avoids signal distortion leading to decryption failure or the generation of incorrect control signals. Simultaneously, the filtered encrypted control command ensures the integrity of its features, improving the stability and security of signal transmission in interference environments.

[0047] S102: Determine the decryption parameters according to the encryption control command, including: first, parsing the encryption control command to obtain its encryption parameters; finally, determining the decryption parameters based on the encryption parameters. The encryption control command typically includes encryption parameters such as the algorithm representation and key index used for encryption. Only after parsing the encryption control command to obtain the decryption parameters can the decryption key and algorithm used for decryption be determined. This ensures that the decryption process is strictly synchronized with the walkie-talkie's encryption process, avoiding decryption failure or command tampering due to mismatched encryption and decryption parameters. Simultaneously, this encryption and decryption process verifies the legality and integrity of the encryption control command received by the voice gateway from the walkie-talkie, thereby preventing attacks or forged commands during transmission.

[0048] S103: Decrypt the encryption control command according to the decryption parameters and generate a decryption control command;

[0049] S104: Based on the decrypted control instructions, generate control signals for controlling the UAV to perform target flight maneuvers.

[0050] After generating the control signal to be sent to the drone, the drone will generate a feedback signal based on its flight attitude to indicate whether it has completed the target flight maneuver. Therefore, a drone remote control method based on a voice gateway, applied to a voice gateway, also includes:

[0051] Receive feedback signals generated by the drone based on its flight attitude; generate voice signals to be sent to the walkie-talkie based on the feedback signals, and use the voice signals to indicate whether the drone has completed the target flight maneuver.

[0052] This invention uses a voice gateway as a relay device for communication between walkie-talkies and drones, improving the flexibility and portability of remote drone control. In scenarios such as fire emergency rescue, drones can be remotely controlled via walkie-talkies without the need for a dedicated remote control or a specific ground controller.

[0053] See Figure 2 As shown, the present invention provides a remote control method for unmanned aerial vehicles (UAVs) based on a voice gateway, applied to a walkie-talkie, wherein the walkie-talkie is communicatively connected to the voice gateway, and includes:

[0054] S201: Receives button signals with corresponding target flight actions. The walkie-talkie includes multiple buttons, and each button is associated with a flight action, such as ascent or descent, through pre-setting. When the operator presses the button for ascent via the walkie-talkie, the walkie-talkie receives the button signal for the target flight action as ascent, effectively improving the portability of remotely controlling the drone via the walkie-talkie.

[0055] S202: Encode the button signal to generate multiple command sequences corresponding to the target flight action; a single button signal may include multiple control parameters. For example, if the target flight action is ascent, the control parameters included in this button signal include, but are not limited to, the ascent command sequence and the ascent altitude command sequence. Therefore, encoding the button signal to obtain multiple command sequences ensures that the encrypted control commands sent to the voice gateway include complete commands, thereby ensuring the reliability and accuracy of the control signals sent to the UAV; at the same time, by converting the button signal into a binary command sequence, the signal transmission efficiency can be effectively improved, ensuring that the UAV can quickly receive the control signal.

[0056] S203: Synthesize multiple instruction sequences to obtain encrypted control commands sent to the voice gateway, including: synthesizing multiple instruction sequences to obtain digital control commands as digital signals; converting the digital control commands into analog control commands as analog signals; and filtering the analog control commands to obtain encrypted control commands. The digital control commands, transmitted as digital signals, are obtained through multiple instruction sequences. Digital signals have strong anti-interference capabilities and are easy to encrypt. Encrypting the digital control commands effectively improves the security of signal transmission. During the analog-to-digital conversion of the digital control commands to obtain analog control commands, noise may be introduced. Filtering effectively removes this noise from the analog control commands, preventing distortion of the encrypted control commands sent to the voice gateway, which could lead to incorrect control signals sent to the UAV and consequently prevent the UAV from completing the target flight maneuvers.

[0057] After receiving the control signal from the voice gateway, the drone generates a feedback signal based on its flight attitude to indicate whether it has completed the target flight maneuver. The voice gateway then generates a voice signal to be sent back to the walkie-talkie based on this feedback signal. Therefore, a drone remote control method based on a voice gateway and applied to a walkie-talkie also includes:

[0058] The system receives voice signals from the voice gateway and generates voice commands based on these signals to indicate whether the drone has completed the target flight maneuver. Specifically, when the drone completes the target flight maneuver, the voice command is to control the walkie-talkie to emit a short "beep-beep" tone. When the drone has not completed the target flight maneuver, the voice command is to control the walkie-talkie to emit a long "beep-" tone. The operator can quickly determine whether the drone has completed the target flight maneuver by listening to the sounds emitted by the walkie-talkie.

[0059] This invention uses a voice gateway as a relay device for communication between walkie-talkies and drones, improving the flexibility and portability of remote drone control. In scenarios such as fire emergency rescue, drones can be remotely controlled via walkie-talkies without the need for a dedicated remote controller or a specific ground controller. At the same time, by receiving voice signals sent by the voice gateway, it is possible to quickly and accurately determine whether the drone has completed the target flight maneuver in scenarios such as fire emergency rescue.

[0060] See Figure 3 As shown, the present invention provides a remote control method for unmanned aerial vehicles (UAVs) based on a voice gateway, applied to a UAV, wherein the UAV and the voice gateway are communicatively connected, including:

[0061] S301: Receives control signals sent by the voice gateway, including target flight actions indicated by key signals from the walkie-talkie.

[0062] S302: Determine the target flight maneuver based on the control signal, including: determining control parameters based on the control signal; and determining the target flight maneuver based on the control parameters. During the generation of encrypted control commands by the walkie-talkie, multiple command sequences are obtained through key signals, such as ascending command sequences and ascending altitude command sequences. When these command sequences are transmitted to the UAV, they need to be converted into parameters that the UAV can read. Therefore, determining the control parameters for controlling the UAV to complete the target flight maneuver through the control signal ensures that the UAV can completely complete the target flight maneuver.

[0063] S303: Obtain flight attitude and generate a feedback signal to be sent to the voice gateway based on the flight attitude.

[0064] This invention uses a voice gateway as a relay device for communication between walkie-talkies and drones, improving the flexibility and portability of remote drone control. In scenarios such as fire emergency rescue, drones can be remotely controlled via walkie-talkies without the need for a dedicated remote controller or a specific ground controller. At the same time, a feedback signal is generated and sent to the voice gateway, enabling the voice gateway to send a signal to the walkie-talkie indicating whether the drone has completed the target flight maneuver.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
