[0062] The present invention discloses a UAV gimbal, a UAV, a UAV control system and a control method thereof. A communication component and a power supply component are detachably connected, and a gimbal main body and a power supply component are detachably connected to a fuselage of the UAV respectively, so that it is convenient to replace the power supply component and troubleshoot the faults of each component, and the maintenance difficulty is low.

[0063] Embodiment 1

[0064] Please also read Figure 1 , is a structural schematic diagram of a drone gimbal provided by an embodiment of the present invention, the drone gimbal includes a gimbal body 11, a communication component 12 and a power supply component 13, the gimbal body 11 includes a bracket 111 and a shooting component 112 arranged on the bracket 111, the communication component 12 is rotatably connected to the bracket 111 through a rotating arm 14, and there is a distance between the communication component 12 and the bracket 111, the communication component 12 is provided with a gimbal control module 121, the gimbal control module 121 is electrically connected to the shooting component 112, the power supply component 13 is detachably connected to the communication component 12, and is used to achieve electrical conduction between the communication component 12 and the shooting component 112.

[0065] In this embodiment, if Figure 2 As shown, the shooting component 112 includes a motor 112a provided on the bracket 111 and an infrared camera module 112b and / or a visible light camera module connected to the motor 112a. Optionally, the shooting component 112 may be provided with an infrared camera module 112b, but the scheme of additionally adding or separately providing a visible light camera module is not excluded. It can be understood that under the action of the motor 112a, the infrared camera module 112b can perform pitch motion, and the method of using a single motor 112a to achieve single-axis motion can reduce the weight of the gimbal body 11, thereby making the overall weight of the drone gimbal smaller.

[0066] Furthermore, in order to arrange the shooting assembly 112 on the bracket 111, the shooting assembly 112 also includes a motor fixing assembly 112c, the motor fixing assembly 112c includes a motor fixing frame 1121 and a motor end cover 1122 arranged on one side of the motor fixing frame 1121, the motor fixing frame 1121 is fixedly connected to the bracket 111, and the motor 112a is arranged on the other side of the motor fixing frame 1121. In other words, the position of the motor 112a relative to the bracket 111 remains fixed, and the infrared camera module 112b is driven to rotate relative to the bracket 111 by the rotation of the motor shaft of the motor 112a, so as to achieve the pitch shooting of the infrared camera module 112b.

[0067] In this embodiment, combined Figure 1 and Figure 2As shown, in order to realize that the communication component 12 can be rotatably connected to the bracket 111, the shooting component 112 is arranged at the front end of the bracket 111, and the communication component 12 is located at the rear end of the bracket 111. The rotating arm 14 is two, namely a first rotating arm 141 and a second rotating arm 142 parallel to and spaced from the first rotating arm 141. One end of the first rotating arm 141 and the second rotating arm 142 are respectively rotatably connected to the two sides of the rear end of the bracket 111, and the other ends of the first rotating arm 141 and the second rotating arm 142 are respectively extended to the two sides of the communication component 12 for fixed connection.

[0068] It can be known that the UAV gimbal realizes the rotational connection of the communication component 12 to the bracket 111 through the first rotating arm 141 and the second rotating arm 142, and also allows a distance between the communication component 12 and the bracket 111, and the distance is approximately equal to the length of the first rotating arm 141 and the second rotating arm 142. When the UAV gimbal is mounted on a UAV, since the UAV usually has a positioning module at the junction of the front end and the middle part of the fuselage, the distance between the communication component 12 and the bracket 111 can correspond to the positioning module at the junction of the front end and the middle part of the UAV fuselage, thereby avoiding the various modules in the communication component 12 (such as the communication module 123, the gimbal control module 121, etc.) causing signal interference to the positioning module, thereby affecting the accuracy of the positioning module in locating the position of the UAV.

[0069] In addition, the distance between the communication component 12 and the bracket 111 allows the weight of the drone gimbal to be more evenly distributed at the front, middle and rear ends of the drone body when the drone gimbal is mounted on the drone, thereby avoiding the weight of the drone gimbal being concentrated at the front end of the drone body, that is, the position of the gimbal body 11 on the drone body. This design is conducive to the smooth flight of the drone.

[0070] The communication component 12 and the bracket 111 are spaced apart from each other, that is, there is also a distance between the communication component 12 and the shooting component 112 , and the communication between the communication component 12 and the shooting component 112 can be achieved through wireless connection or wired connection.

[0071] As an optional method, the communication component 12 and the shooting component 112 are wirelessly connected, for example, via Bluetooth, WiFi, 4G, 5G, etc.

[0072] As another optional implementation, the communication component 12 is connected to the shooting component 112 by wire. Figure 2As shown, the first rotating arm 141 includes a first arm housing 1411 and a first arm cover 1412, the first arm cover 1412 and the first arm housing 1411 are covered and connected to form a first wiring space (not marked), and the first wiring space is connected to the interior of the shooting component 112 and the interior of the communication component 12, the second rotating arm 142 includes a second arm housing 1421 and a second arm cover 1422, the second arm cover 1422 and the second arm housing 1421 are covered and connected to form a second wiring space (not marked), and the second wiring space is connected to the interior of the shooting component 112 and the interior of the communication component 12, and the lines of the communication component 12 extend from the first wiring space and the second wiring space to the communication component 12 and are connected to the gimbal control module 121.

[0073] It can be seen from this that the line of the shooting component 112 of the pan / tilt of the present application can extend from the first wiring space and the second wiring space to the communication component 12 and connect to the pan / tilt control module 121. When inspecting, the first arm cover 1412 and the second arm cover 1422 can be disassembled, and the inspection difficulty is low. The line is hidden in the first wiring space and the second wiring space, which can effectively protect the line. In addition, when the communication component 12 rotates relative to the bracket 111, the line of the shooting component 112 can rotate with the first rotating arm 141 and the second rotating arm 142, avoiding the situation where the line is entangled with the first rotating arm 141 and the second rotating arm 142 and causes damage to the line.

[0074] Further, the first arm housing 1411 and the second arm housing 1421 are long strip housings, the first arm housing 1411 includes a first end 141a and a second end 141b in the length direction, the first end 141a is fixedly connected to one side of the communication component 12, the first end 141a is provided with a first opening 1411a connecting the communication component 12 and the first wiring space, the second end 141b is rotatably connected to one side of the rear end of the bracket 111, the second end 141b is provided with a first opening 1411a connecting the first wiring space and the shooting component 1 The first wiring opening 1411b inside the bracket 12, the second arm housing 1421 includes a third end 142a and a fourth end 142b in the length direction, the third end 142a is fixedly connected to the other side of the communication component 12, the third end 142a is provided with a second opening 1421a connecting the interior of the communication component 12 and the second wiring space, the fourth end 142b is rotatably connected to the other side of the rear end of the bracket 111, and the fourth end 142b is provided with a second wiring opening 1421b connecting the second wiring space and the interior of the shooting component 112.

[0075] From the above, it can be seen that the path of the line of the shooting component 112 extending to the communication component 12 and connecting with the pan / tilt control module 121 is:

[0076] Inside the photographing component 112 → first wiring port 1411b → first wiring space → first opening 1411a → inside the communication component 12 ; and inside the photographing component 112 → second wiring port 1421b → second wiring space → second opening 1421a → inside the communication component 12 .

[0077] In this embodiment, if Figure 1 and Figure 3 As shown, the communication component 12 can rotate relative to the bracket 111 and switch between a first posture position and a second posture position under the action of the first rotating arm 141 and the second rotating arm 142, wherein the first posture position is the position where the communication component 12 is located above the gimbal body 11, and the second posture position is the position where the communication component 12 is located at the rear end of the bracket 111.

[0078] Specifically, when the communication component 12 is located at the first posture position, the communication component 12 is separated from the power component 13, and when the communication component 12 is located at the second posture position, the communication component 12 is connected to the power component 13. That is to say, when the drone gimbal is mounted on the drone, the power component 13 and the communication component 12 can be connected to the drone respectively first, and then the communication component 12 is connected to the power component 13 by adjusting the posture position of the communication component 12, thereby reducing the difficulty of mounting the drone gimbal and making the operation simpler. The specific process can be: the power component 13 is connected to the rear end of the drone fuselage, and the gimbal body 11 is connected to the front end of the drone fuselage. At this time, the communication component 12 is located at the second posture position, and the communication component 12 is rotated relative to the first posture position to connect the communication component 12 to the power component 13, thereby completing the mounting of the drone gimbal.

[0079] From the above, it can be seen that the method of installing or removing the drone gimbal from the drone body is simple and quick, and the communication component 12 and the power component 13 are separable, which is convenient for replacing the power component 13 and repairing the drone gimbal.

[0080] In this embodiment, combined again Figure 1 and Figure 2As shown, the bracket 111 includes an external bracket 11a and an internal bracket 11b connected to the external bracket 11a, the communication component 12 is rotatably connected to the external bracket 11a, and the shooting component 112 is arranged on the internal bracket 11b. The communication component 12 and the shooting component 112 are arranged respectively by the external bracket 11a and the internal bracket 11b, so that the communication component 12 and the shooting component 112 can be prevented from interfering with each other. From a structural point of view, this method can make the relative positions of the various components of the drone gimbal reasonably arranged, make full use of the internal and external space of the bracket 111, and meet the design concept of miniaturization and lightweight of the drone gimbal.

[0081] Furthermore, the external support 11a includes a first external frame 111a and a second external frame 111b, the first external frame 111a is covered above the internal support 11b to form a covering space (not marked), the second external frame 111b is connected to the internal support 11b to form an angle space (not marked), the angle space is located at the front end of the support 111, the shooting component 112 is located in the angle space, the rotating arm 14 is rotatably connected to the second external frame 111b, and the rotating support 111 is located outside the angle space. The shooting component 112 is located in the angle space and can be protected by the second external support 11a and the internal support 11b to prevent it from being damaged by impact.

[0082] Specifically, the second external frame 111b is a square-shaped frame, the number of the internal brackets 11b is connected to the two sides of the second external frame 111b, and the number of the first external frame 111a is connected to the two internal brackets 11b. It can be understood that the interval between the two internal brackets 11b is connected to the interval between the two first external frames 111a, and the heat generated by the rear end of the infrared camera module 112b when it is working can be dissipated upward through the above-connected intervals to the outside of the bracket 111, and the rear end of the infrared camera module 112b faces the hollow part of the square-shaped second external frame 111b, and the heat generated by the rear end of the infrared camera module 112b when it is working can be dissipated to the outside of the bracket 111 through the hollow part.

[0083] That is to say, the heat generated by the infrared camera module 112b when working can be dissipated to the outside of the bracket 111 in multiple directions, preventing the infrared camera module 112b from overheating and causing malfunction. In addition, by designing the structure of the external bracket 11a and the internal bracket 11b, the weight of the external bracket 11a and the internal bracket 11b can be effectively reduced, thereby realizing a lightweight design of the drone gimbal.

[0084] In addition, if Figure 2As shown, while realizing the lightweight design of the drone gimbal, the cover space formed between the first external frame 111a and the internal frame 11b also provides a connection position for setting the shooting component 112. The internal frame 11b is provided with a shock absorbing component 111c located in the cover space, and the frame 111 also includes a fixed frame 11c, which is connected to the shock absorbing component 111c and the shooting component 112. The shooting component 112 is set by connecting the shock absorbing component 111c to the fixed frame 11c, which can reduce the impact of the vibration generated during the flight of the drone on the shooting component 112, prevent the shooting component 112 from shaking, improve the stability of the image captured by the shooting component 112, and thus improve the image quality.

[0085] Specifically, the shock absorbing component 111c is a shock absorbing ball, and there are four of them, which are arranged at intervals in the internal bracket 11b and connected to the fixed frame 11c. The internal bracket 11b and the fixed frame 11c are connected by four shock absorbing components 111c distributed at four corners in a square shape, and the shock absorbing effect is better.

[0086] Furthermore, in order to realize the detachable connection of the drone gimbal to the drone, the second external frame 111b includes two side plates 11aa, a bottom plate 11ab and a transverse plate 11ac, the two side plates 11aa are arranged at intervals, the transverse plate 11ac is connected between the two side plates 11aa and arranged near the position of the first external frame 111a, the bottom plate 11ab extends from the position of the two side plates 11aa away from the first external frame 111a to the angle space, and the two sides of the bottom plate 11ab extend outward to form a fixing part 11ad, and the fixing part 11ad is provided with a fastener 11ae for detachable connection to the drone. Specifically, the fastener 11ae can be a bolt, a stud, etc.

[0087] In this embodiment, if Figure 2 and Figure 4 As shown, the communication component 12 includes a main shell 122 and a communication module 123 disposed in the main shell 122. The main shell 122 is rotatably connected to the bracket 111 through the rotating arm 14. The gimbal control module 121 is disposed in the main shell 122. The communication module 123 is electrically connected to the gimbal control module 121 and the power supply component 13.

[0088] Specifically, the pan-tilt control module 121 includes a pan-tilt main control board 121a and an infrared core board 121b electrically connected to the pan-tilt main control board 121a, and the infrared core board 121b is provided with a memory card to store images or data, and the bottom shell 12a is provided with a plug-in port 1224 corresponding to the memory card. The communication module 123 includes an encoder 123a and a communication link module 123b electrically connected to the encoder 123a, and the encoder 123a is electrically connected to the pan-tilt control module 121 and the power supply assembly 13. Specifically, the encoder 123a is an analog signal digital encoder 123a, which is used to encode the analog signal CVBS into a digital signal H.264 video data stream, and the communication link module 123b is an image data integrated communication link module, which is used to send the digital video stream and the digital control stream to the ground control site of the drone.

[0089] Furthermore, the communication component 12 also includes two antennas 124, which are respectively arranged on both sides of the main shell 122 and are electrically connected to the communication link module 123b. The two antennas 124 are used to establish a communication connection with the ground controller of the UAV.

[0090] In this embodiment, if Figure 4 As shown, the main housing 122 includes a bottom housing 12a, a middle frame 12b and a top housing 12c. The middle frame 12b is connected between the bottom housing 12a and the top housing 12c, and is used to form a first accommodation space (not marked) and a second accommodation space (not marked) with the bottom housing 12a and the top housing 12c respectively. The second accommodation space is connected to the first accommodation space. The pan-tilt control module 121 is arranged in the first accommodation space, and the communication module 123 is arranged in the second accommodation space. It can be understood that the pan-tilt control module 121 and the communication module 123 are respectively arranged by forming the first accommodation space and the second accommodation space with the bottom housing 12a and the top housing 12c through the middle frame 12b, making full use of the space, and setting different processing modules at intervals, which not only realizes the miniaturization design of the pan-tilt, but also avoids mutual interference between different processing modules.

[0091] Furthermore, combined with Figure 4 and Figure 5As shown, the middle frame 12b is a U-shaped frame, and the main housing 122 also includes a cover plate 12d, which is connected to the top shell 12c, the middle frame 12b and the bottom shell 12a, and closes the open end of the middle frame 12b. The bottom shell 12a is provided with a groove 1221 at one end close to the cover plate 12d, and the groove 1221 is provided with a first signal interface 12aa, and the power supply component 13 is provided with a second signal interface 13a for connecting with the first signal interface 12aa. It can be known that when the communication component 12 rotates from the first posture position to the second posture position relative to the bracket 111, the first signal interface 12aa is connected to the second signal interface 13a, so as to realize the electrical conduction between the power supply component 13 and the communication component 12.

[0092] Specifically, the power supply assembly 13 includes a power supply body 131 and a boss 132 protruding upward from the top surface 131a of the power supply body 131. The boss 132 is provided with a connecting surface 132a connected to the top surface 131a of the power supply body 131 to form a step. The connecting surface 132a is provided with the second signal interface 13a.

[0093] Furthermore, a first holding component 12d is provided on the side of the middle frame 12b, and a second holding component 133 is provided on the top surface 131a of the power supply body 131 corresponding to the first holding component 12d, and when the first signal interface 12aa is matched and connected with the second signal interface 13a, the first holding component 12d is detachably connected to the second holding component 133. Thus, when the communication component 12 is in the second posture position and is electrically connected with the power supply component 13 through the second signal interface 13a of the first signal interface 12aa, the communication component 12 is also connected through the first holding component 12d and the second holding component 133, effectively ensuring the reliability of the connection between the first signal interface 12aa and the second signal interface 13a.

[0094] Specifically, a through slot 1222 is further provided on the side of the middle frame 12b, a window 1223 is provided on the side of the bottom shell 12a below the through slot 1222, the first holding component 12d includes a pressing portion 12da and a buckle portion 12db, the pressing portion 12da is slidably provided in the through slot 1222, the buckle portion 12db extends downward from the pressing portion 12da through the window 1223, the top surface 131a of the power source body 131 is provided with a baffle 134 extending upward, and the second holding component 133 is a slot provided on the baffle 134. The middle frame 12b is provided with a fixing seat 12e corresponding to the through slot 1222, and an elastic component 12f is provided between the fixing seat 12e and the pressing portion 12da. That is, when the communication component 12 is rotated to the second posture position, the pressing portion 12da is pressed so that the buckle portion 12db is aligned with the second holding component 133. After the pressing portion 12da is released, the pressing portion 12da is reset under the action of the elastic component 12f so that the buckle portion 12db is locked in the second holding component 133, thereby realizing the detachable connection between the communication component 12 and the power supply component 13. Preferably, the elastic component 12f can be a spring.

[0095] In this embodiment, the power supply body 131 also includes a side surface 131b adjacent to the top surface 131a, and the side surface 131b is provided with a first connection portion 13b for detachably connecting to the drone. That is to say, the drone gimbal in this embodiment is detachably connected to the drone through the fastener 11ae of the fixed frame 11c and the first connection portion 13b of the side surface 131b of the power supply body 131. From the overall point of view, the front and rear ends of the drone gimbal (the front and rear ends are the gimbal body 11 and the power supply assembly 13, respectively) are connected to the drone, and the connection is more secure and reliable. The first connection portion 13b is preferably a press buckle to facilitate the detachment or connection of the power supply assembly 13 to the drone fuselage.

[0096] In this embodiment, if Figure 4 As shown, the side of the middle frame 12b is convex outward to form a sub-frame 1223, the interior of the sub-frame 1223 is connected to the second accommodating space and the first accommodating space, and the sub-frame 1223 is provided with a heat dissipation hole 122a. The drone gimbal also includes a heat dissipation fan 125, which is arranged in the sub-frame 1223 and blows air toward the heat dissipation hole 122a. Through this heat dissipation design, the heat generated by each module (gimbal control module 121 and communication module 123, etc.) in the communication component 12 during operation can be quickly dissipated to the outside of the main housing 122, effectively ensuring the normal operation of the communication component 12.

[0097] Furthermore, the surfaces of the bottom shell 12a, the middle frame 12b and the top shell 12c are all provided with a plurality of air inlet holes 122b, and the air inlet holes 122b are connected to the first accommodation space and the second accommodation space. It can be known that when the cooling fan 125 is started to dissipate heat, the air carrying the heat generated by each module in the communication component 12 is emitted from the cooling hole 122a, and the air can be supplemented through the air inlet holes 122b to maintain the balance of the air pressure inside and outside the main shell 122, and form an airflow loop to accelerate the heat dissipation and improve the heat dissipation effect. It can be understood that when the cooling fan 125 is not started or fails, the heat generated by the various modules in the communication component 12 can be spontaneously dissipated to the heat dissipation hole 122a and the air inlet hole 122b to the outside of the main shell 122, which can also ensure the dissipation of heat. Although the heat dissipation effect is worse than starting the cooling fan 125, it can prevent the communication component 12 from overheating rapidly when the cooling fan 125 fails, and provide time for restarting the cooling fan 125.

[0098] The first embodiment of the present invention provides a drone gimbal, which can be rotatably connected to the gimbal body through a communication component, and the power component and the communication component are detachably connected, so that when the power supply needs to be replaced, the power component can be directly removed for replacement, and when a fault occurs, the power component can be separated from the gimbal body and the communication component for inspection and repair, and the repair difficulty is low and the efficiency is high. When the drone gimbal is applied to a drone, the gimbal body and the power component can be detachably installed on the drone, which is convenient for the drone to disassemble and assemble the gimbal, and the power component can simultaneously supply power to the drone and the gimbal, reducing the overall weight.

[0099] Furthermore, since there is a distance between the communication component and the bracket, when the UAV gimbal is mounted on the UAV body, the distance can correspond to the positioning module setting inside the UAV body, thereby avoiding the gimbal body and other modules in the communication component (such as the communication module, gimbal control module, processing module, etc.) causing signal interference to the positioning module, effectively ensuring that the positioning module accurately obtains the UAV's positioning information and data transmission.

[0100] Furthermore, the detachable connection between the communication component and the power supply component is achieved by the cooperation of the first retaining component and the second retaining component, that is, the cooperation of the buckle portion and the slot, which makes disassembly and assembly easy and the connection reliable.

[0101] In addition, the communication component can be rotated to a second posture position relative to the bracket. At this time, the communication component is located on the power component and can be detachably connected to the power component. When the UAV gimbal is applied to the UAV, the power component can be detachably connected to the power compartment at the rear end of the fuselage, and the gimbal body can be detachably connected to the front end of the fuselage, so that the center of gravity of the UAV gimbal is closer to its center of mass and the weight distribution is more even.

[0102] Embodiment 2

[0103] See also 6 to Figure 8 , which is a schematic structural diagram of a drone provided in the second embodiment of the present invention, the drone comprises a drone body 21 and the drone gimbal of the first embodiment, and the drone gimbal is detachably connected to the drone body 21 .

[0104] In this embodiment, combined with Figure 6 and Figure 7 As shown, the UAV gimbal is located at the top of the UAV fuselage 21, and the UAV fuselage 21 includes a front end 21a, a middle part and a rear end 21b arranged in sequence. A positioning module is provided in the UAV fuselage 21 corresponding to the intersection of the front end 21a and the middle part. The gimbal body 11 is detachably connected to the front end 21a of the UAV fuselage 21, the communication component 12 is located in the middle part of the UAV fuselage 21 and extends from the middle part of the UAV fuselage 21 to the rear end 21b of the UAV fuselage 21, and the distance between the communication component 12 and the bracket is set corresponding to the positioning module, and the power supply component 13 is arranged in the middle part of the UAV fuselage 21 and extends to the rear end 21b of the UAV fuselage 21.

[0105] It can be known that the communication component 12 is rotatably connected to the bracket through the rotating arm 14, so that there is a distance between the communication component 12 and the bracket, and the distance corresponds to the positioning module setting, that is, the rotating arm 14 is located above the positioning module, thereby avoiding the gimbal control module, the communication module in the communication component 12 and the processing module in the gimbal body 11 causing signal interference to the positioning module, and the rotating arm 14 is divided into a first rotating arm and a second rotating arm parallel to the first rotating arm and arranged at an interval, which can avoid the rotating arm 14 blocking the positioning module above the positioning module, causing interference to the signal of the positioning module, and effectively ensure that the positioning module can accurately obtain the positioning information of the drone and transmit signals.

[0106] In addition, this design can also make the weight distribution of the drone gimbal more balanced. The weight of the gimbal body 11 is distributed at the front end 21a of the drone body 21, and the weight of the communication component 12 and the power supply component 13 are distributed in the middle and rear end 21b of the drone body 21, thereby avoiding the situation where the weight of the drone gimbal is concentrated at the front end 21a or the rear end 21b of the drone body 21, which causes the overall center of gravity and center of mass of the drone to deviate too much, thereby causing unstable flight.

[0107] Furthermore, if Figure 7As shown, the middle part of the drone body 21 is provided with a power supply compartment 211 extending to the rear end 21b of the drone body 21, and the power supply assembly 13 is detachably accommodated in the power supply compartment 211, and the power supply assembly 13 is used to supply power to the drone body 21. It can be understood that the power supply assembly 13 can supply power to the communication assembly 12, the gimbal body 11 and the drone body 21 at the same time, and the integrated power supply method can reduce the overall weight of the drone, and when replacing the power supply, only one set of power supply needs to be replaced, and there is no need to replace the power supplies of the drone gimbal and the drone body 21 separately, which is more convenient to operate.

[0108] The specific steps of installing the drone gimbal on the drone body in this application are as follows:

[0109] (1) The communication component 12 is located at the first posture position, and the gimbal body 11 is connected to the front end 21a of the drone body 21. Figure 7 As shown;

[0110] (2) The power supply assembly 13 is accommodated in the power supply compartment 211. Figure 8 As shown;

[0111] (3) The communication component 12 rotates relative to the pan / tilt body 11 to switch from the first posture position to the second posture position. At this time, the communication component 12 is connected to the power supply component 13. Figure 6 shown.

[0112] The order of step (1) and step (2) can be reversed or performed simultaneously, and the entire installation process is relatively simple and has low operating difficulty.

[0113] An embodiment of the present invention provides a drone, in which the spacing between a communication component and a bracket corresponds to the setting of a positioning module in a drone body, thereby avoiding signal interference to the positioning module caused by various modules of the drone gimbal (such as a processing module, a gimbal control module, and a communication module, etc.), and effectively ensuring that the positioning module accurately obtains the positioning information of the drone and transmits data.

[0114] In addition, the drone gimbal can be detachably connected to the drone body, making it easy to disassemble and assemble the gimbal and to inspect and repair the drone gimbal and drone body separately, making maintenance easy and efficient. The power supply component can power the drone and the drone gimbal at the same time, reducing the overall weight and extending the drone's aerial photography time.

[0117] An embodiment of the present invention provides a drone control system, which establishes a communication connection between a drone remote controller and a drone gimbal through a signal transmitter, and also establishes a communication connection between the drone remote controller and a drone body, so that the drone remote controller can simultaneously control the drone body and the drone gimbal, and establish a communication connection between the two.

[0118] Embodiment 4

[0119] like Fig. 9 As shown, it is a flow chart of a control method of a drone control system provided by an embodiment of the present invention. The drone control system is the drone control system of embodiment three, and the drone remote controller is provided with a control module.

[0120] The method comprises the following steps:

[0121] 401. The control module sends a pan-tilt control signal to the signal transmitter, and the pan-tilt control signal is transmitted to the communication module of the communication component via the signal transmitter; and after executing step 401, execute step 402.

[0122] 402. The communication module of the communication component receives the gimbal control signal and sends it to the gimbal control module, and then sends it to the shooting component via the gimbal control module; and after executing step 402, execute step 403.

[0123] 403 . The shooting component starts shooting according to the gimbal control signal and sends a shooting signal to the gimbal control module; and after executing step 403 , execute step 404 .

[0124] 404. The gimbal control module collects images and data information according to the shooting signal and sends them to the communication module of the communication component, which is then transmitted to the signal transmitter via the communication module of the communication component; and after executing step 404, execute step 405.

[0125] 405. The signal transmitter receives the image and data information and sends it to the control module.

[0126] For example, when the user presses the shooting button on the drone remote control or touches the shooting icon on the display screen, the control module sends a shooting command to the signal transmitter, and the shooting command is transmitted to the communication module of the communication component via the signal transmitter. The communication module of the communication component receives the shooting command and sends it to the gimbal control module, which is then sent to the shooting component via the gimbal control module. The shooting component receives the shooting command to start shooting and sends the shooting image signal and the data signal during shooting to the gimbal control module. The gimbal control module collects image and data information (such as time, height above the ground, longitude and latitude, and temperature, etc.) according to the image signal and data signal and sends it to the communication module of the communication component. The communication module of the communication component integrates the image signal and the data signal to form an integrated image and data signal and transmits it to the signal transmitter. The signal transmitter receives the integrated image and data signal and parses it into image and data information and sends it to the control module. The display screen of the drone remote control displays the image and data information.

[0127] Embodiment 4 of the present invention provides a control method for a drone system. By implementing the control method, the drone controller can control the shooting component to shoot and the gimbal control module to collect images and data, and transmit the collected images and data back to the drone controller.
