[0053] Embodiment 1

[0054] Please refer to Figures 1 to 4 , Embodiment 1 of the present utility model is: to provide a drone communication control method based on an LED display screen cluster and a drone communication system applying the control method.

[0055] The drone communication system includes a drone 1, a control handle 2, and a repeater group 3. The repeater group 3 is arranged on the LED display screen cluster. The control handle 2 is used to send flight control signals. The repeater group 3 is communicatively connected to the control handle 2 to receive the flight control signals. The repeater group 3 is wirelessly communicatively connected to the control handle 2 to transmit the flight control signals to the drone 1, and the drone 1 performs flight actions according to the flight control signals.

[0056] Of course, in other embodiments of the present utility model, the LED display screen cluster can be replaced by other devices (for example: utility poles, street lights, etc.), and they all fall within the protection scope of the present utility model.

[0057] In this embodiment, the flight control signal generated by the control handle 2 can be transmitted to the UAV 1 through the repeater group 3 provided on the LED display screen cluster. Therefore, this UAV communication system can increase the control range and area of the control handle 2 over the UAV 1 through the repeater group 3. When this UAV communication system is applied to the urban flight scenario of the UAV 1, it can ensure the reliability and stability of the controlled flight of the UAV 1 in complex environments such as cities and buildings. In addition, controlling the UAV 1 by setting the repeater group 3 helps reduce the dependence of the UAV 1 on the power intensity of the communication signal, thereby reducing the UAV communication transmit power and receive power, reducing the power consumption of the UAV 1, and facilitating the improvement of the long-distance flight ability of the UAV 1.

[0058] As Figure 4 shown, the control method includes the following steps: A repeater group 3 is set on the LED display screen cluster, the control handle 2 is communicatively connected to the repeater group 3. When the UAV 1 flies into the relay communication coverage area of the repeater group 3, it is determined whether the UAV 1 enables the relay communication function; if so, the UAV 1 receives the connection signal sent by the repeater group 3 and stores the rolling code of the connection signal. The UAV 1 sends a response signal to the repeater group 3 to enable the UAV 1 to be communicatively connected to the repeater group 3. The flight control signal of the control handle 2 is sent to the repeater group 3, and the repeater group 3 sends the flight control signal to the UAV 1; if not, the UAV does not receive the connection signal.

[0059] To further increase the control range of the remote control device over the UAV 1, the repeater group 3 includes a plurality of relay communication modules 31 to form a communication link through the plurality of relay communication modules 31; reference can be made to Figure 3 , in this embodiment, the plurality of relay communication modules 31 are respectively provided on a plurality of LED display screen clusters arranged in sequence along the direction away from the control handle 2. The communication coverage areas 6 of two adjacent relay communication modules 31 at least partially overlap to form a second overlapping area 9; the relay communication module 31 sends the connection signal within its communication coverage area 6. It is easy to understand that the relay communication coverage area 6 is composed of the communication coverage areas 6 of all the relay communication modules 31 of the repeater group 3.

[0060] Specifically, LED display screens can be set on a large number of buildings in a large area of the city. A plurality of LED display screens can be formed into an LED display screen cluster. A plurality of relay communication modules 31 are respectively set on the plurality of LED display screens, and the plurality of relay communication modules 31 form a communication link, which can effectively increase the communication range between the control handle 2 and the UAV 1 in the city.

[0061] In this embodiment, the drone 1 flies within the control area 7 of the control handle 2 and the communication coverage area 6 of the repeater group 3, including the steps:

[0062] Among two adjacent relay communication modules 31, the relay communication module 31 closer to the control handle 2 is used as the proximal communication module, and the other relay communication module 31 is used as the distal communication module. The drone 1 is communicatively connected to the proximal communication module, and the drone 1 flies within the communication coverage area 6 of the proximal communication module;

[0063] When the drone 1 flies to the second overlapping area 9 between the proximal communication module and the distal communication module, it is determined whether the drone 1 receives the distal connection signal of the distal communication module;

[0064] If so, the drone 1 receives the distal connection signal and stores the distal rolling code of the distal connection signal. The drone 1 sends a distal response signal to the distal communication module, so that the drone 1 is communicatively connected to the distal communication module, so that the drone 1 can fly within the communication coverage area 6 of the distal communication module;

[0065] If not, the drone 1 does not receive the distal connection signal, and the drone 1 does not fly within the communication coverage area 6 of the distal communication module.

[0066] The drone 1 takes off within the control range of the remote control device. Under the action of the relay communication function of the repeater group 3, the drone 1 can fly in a direction away from the remote control device and is communicatively connected to multiple relay communication modules 31 in sequence; As an example: a plurality of relay communication modules 31 arranged in sequence along the direction away from the control handle 2 are numbered in order. Then, when the drone 1 is communicatively connected to the Nth relay communication module 31, the drone 1 can fly within the control range and the communication coverage areas 6 of the first relay communication module 31 to the Nth relay communication module 31.

[0067] When the drone 1 flies to the first overlapping area 8 or the second overlapping area 9, a relay communication prompt can be displayed on the control handle 2 for the user to autonomously select whether to use the relay communication function; as an example: when the drone 1 flies to the first overlapping area 8, the control handle 2 can receive a connection signal, and a special mark can be displayed on the display screen of the control handle 2 to prompt the relay communication coverage area 6, the communication coverage areas 6 of the respective relay communication modules 31 of the repeater group 3, and the no-fly area. The signal amplifier on the sending card of the relay communication module 31 emits a connection signal within its communication coverage area 6, and the connection signal includes a rolling code, which is a bar code formed by a combination of 11-21 letters and settings. When the drone 1 selects to enable the relay communication function, the drone 1 receives the connection signal to connect the drone 1 to the relay communication module 31, and the control handle 2 is connected to the relay communication module 31 closest to the control area 7. At this time, the flight control signal sent by the control handle 2 can be transmitted to the drone 1 through the repeater group 3, which can greatly increase the controllable range of the control handle 2 over the drone 1.

[0068] Please refer to Figure 2 , in this embodiment, the relay communication module 31 includes a signal rolling code generator 312, a signal converter 311, and a signal receiver 313. The signal rolling code generator 312 is used to generate a rolling code. When the drone 1 flies within the communication coverage area 6 of the relay communication module 31, the drone 1 is communicatively connected to the communication module, and the communication module sends the rolling code to the drone 1 so that the communication module can identify the identity information of the drone 1 based on the rolling code. The signal converter 311 is used to forward communication data to the adjacent relay communication module 31 to connect multiple relay communication modules 31 in series to form a communication link. The signal receiver 313 is used to obtain the rolling code in the flight control signal and send the flight control signal to the corresponding drone 1 or the relay communication module 31 at the next node of the communication link according to the rolling code.

[0069] Please refer to Figure 1 , the drone communication system further includes a central control device 4. Multiple relay communication modules 31 are communicatively connected to the central control device 4. The central control device 4 establishes the communication link for the multiple relay communication modules 31. The central control device 4 includes a memory 41, and the memory 41 is used to store the serial code of the drone 1, the rolling code corresponding to the drone 1, and the status information of the rolling code.

[0070] The central control device 4 can obtain the communication coverage areas 6 of each relay communication module 31 to generate a relay communication coverage area 6 composed of multiple communication coverage areas 6, and generate information on the relay communication coverage area 6, each communication coverage area 6, and the no-fly area, and transmit this information to the control handle 2.

[0071] In this embodiment, the rolling code of the relay communication module 31 is generated by the signal rolling code generator 312. The rolling code in the UAV communication system is unique to ensure the anti-interference ability of the communication between the UAV 1 and the repeater group 3; among two adjacent relay communication modules 31, the signal receiver 313 of one relay communication module 31 acquires and analyzes the transmission signal of the other relay communication module 31 to match the corresponding UAV 1 or control handle 2 through the rolling code carried by the transmission signal.

[0072] Please continue to refer to Figure 2 , in this embodiment, the UAV communication system further includes a cloud platform 5. Multiple said relay communication modules 31 are all communicatively connected to the cloud platform 5. The relay communication module 31 receives the image information collected by the UAV 1 and transmits the image information to the cloud platform 5, and the cloud platform 5 stores the image information.

[0073] Based on the establishment of the cloud platform 5 in the UAV communication system, in the control method, when the UAV 1 flies within the relay communication coverage area 6, it further includes the steps: the image information collected by the UAV 1 is sent to the repeater group 3, and the repeater group 3 uploads the image information to the cloud platform 5.

[0074] In some preferred embodiments, a flash transmission function can be implemented between the relay communication module 31 and the UAV 1. Image information such as pictures or videos taken by the UAV 1 can be transmitted to the background control system or cloud platform 5 of the UAV 1 through the relay communication module 31 for storage and reading.

[0075] In this embodiment, in the control method, when the UAV 1 flies within the control area 7 of the control handle 2 and the communication coverage area 6 of the repeater group 3, it further includes the steps:

[0076] Obtain an instruction to turn off the relay communication function;

[0077] Judge whether the UAV 1 is located within the control area 7; if so, turn off the relay communication function of the UAV 1; if not, the UAV 1 flies to the control area 7 and the relay communication function of the UAV 1 is turned off.

[0078] In the control method, after the relay communication function of the drone 1 is turned off, the following steps are further included: the drone 1 retains the rolling codes of a preset number of the relay communication modules 31 closest to the control handle 2, deletes the rolling codes of other relay communication modules 31, and the central control device 4 recovers the rolling codes deleted by the drone 1.

[0079] When the user manually turns off the relay communication function and the drone 1 is flying within the control area 7, the drone 1 will automatically disconnect the communication connection with the repeater group 3 so that the drone 1 can communicate directly with the control handle 2. During this process, the documents that have been transmitted or are being transmitted are not affected by the signal switch. When the user manually turns off the relay communication function and the drone 1 is flying in an area outside the control area 7, the control handle 2 will remind the user that the drone 1 needs to return to the control area 7 first to avoid disconnection between the control handle 2 and the drone 1.

[0080] After the drone 1 is restarted due to power failure or the relay communication function is manually turned off, some of the rolling codes can be deleted to avoid the problem of inconvenient operation due to excessive amount of stored rolling codes in the drone 1.

[0081] As an example: The drone 1 establishes communication connections with 15 sequentially arranged relay communication modules 31. During flight, the drone 1 stores 15 rolling codes to ensure that the drone 1 can fly and return within the communication coverage area 6 of the 15 relay communication modules 31. The rolling codes are numbered in ascending order according to the distance between their corresponding relay communication modules 31 and the control handle 2. If the preset number is set to 10, then after the drone 1 is restarted due to power failure or the relay communication function is manually turned off, the drone 1 only saves the 1st - 10th rolling codes and deletes the 11th - 15th rolling codes. The 11th - 15th rolling codes will be recorded and archived by the central control device 4 for rolling code recovery. In addition, the central control device 4 will also correspondingly save the serial number of the drone 1 using the rolling code and change the status information of the recovered rolling code to the recovered state.

[0082] When all the rolling codes in the entire drone communication system have been used up, the central control device 4 can randomly release the previously recovered rolling codes and randomly provide them for use by the relay communication modules 31. Recycling the rolling codes can reduce the load phenomenon caused by excessive rolling code data in the drone communication system.

[0083] In order to enable relay communication for multiple drones 1 simultaneously, the control method further includes the steps: when the drone 1 is communicatively connected to the repeater group 3, the repeater group 3 generates new rolling codes, and the repeater group 3 sends a new connection signal, and the new connection signal includes the new rolling codes.

[0084] Specifically, one relay communication module 31 in the repeater group 3 can generate multiple rolling codes. Therefore, the relay communication module 31 can be connected to multiple drones 1 simultaneously. Since the rolling codes are unique, once a drone 1 is connected to the relay communication module 31 and the rolling code is used, the relay communication module 31 will generate a new rolling code for other unconnected drones 1 to use. Other drones 1 and the relay communication module 31 authenticate their identities through the new rolling code, and the transmission information between them is encrypted using the new rolling code, thus achieving secure transmission.

[0085] In this embodiment, multiple relay communication modules 31 of the repeater group 3 are respectively arranged on multiple LED display screens. Specifically, the relay communication module 31 is integrated into the main controller of the LED display screen. The central control device 4 includes a controller 42 to control the LED display screen to display images. Therefore, the LED display screen can achieve communication control through the relay communication module 31.

[0086] As a preferred implementation manner, a wireless charging module 10 can be arranged on the LED display screen. The wireless charging module 10 is arranged on the LED display screen cluster, and the wireless charging module 10 is used to wirelessly charge the drone 1.

[0087] In summary, the drone communication control method provided by the present invention is applied to the urban flight scenario of the drone 1. The repeater group 3 can be arranged on the LED display screen cluster to increase the control range and area of the control handle 2 over the drone 1 through the repeater group 3, and ensure the strength and quality of the flight control signal received by the drone 1, thus ensuring the reliability of the drone 1 flying in complex environments such as cities and buildings. In addition, this control method reduces the dependence of drone communication on the signal power intensity, thereby reducing the transmission power and reception power of drone communication, reducing the power consumption of the drone 1, and being beneficial to improving the long-distance flight ability of the drone 1. Furthermore, this control method realizes secure communication between the drone 1 and the control handle 2 through rolling codes, avoiding interference of the drone 1 by other signals.

[0088] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present invention.
