[0044] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0045] The embodiment of the present application provides an operation system. The operation system includes an execution system and a drone, and the execution system is deployed on the drone. It can be applied to scenes such as agriculture and industry. In the field of plant protection, various operation equipment can be installed on the drone to achieve operations such as spreading pesticides, seeds, and powders.

[0046] Among them, the drone can be used in agricultural plant protection operations, to spread crops, and to spread solid materials such as seeds, granules, powders, etc. to the target area.

[0047] The execution system may be, but is not limited to, a spreading system. The spreading system may be used to spread solid materials such as seeds, granules, powders, etc.

[0048] The present application embodiment takes the execution system deployed on the drone as a spreading system as an example for explanation. Figure 1 and Figure 2 , Figure 1 This is one of the structural schematic diagrams of the spreading system provided in the embodiment of the present application. Figure 2 This is a second structural diagram of the spreading system provided in the embodiment of the present application. Figure 1 and Figure 2 As shown, the sowing system includes a sowing mechanism 100 and a material box 200, wherein the material box 200 is installed on the body of the drone and is used to contain materials, such as seeds, granules, powders, etc. The sowing mechanism 100 is connected to the material box 200 and can rotate to sow the materials in the material box 200 that fall into the sowing mechanism 100. When the sowing system is performing a sowing operation, the materials in the material box 200 fall into the sowing mechanism 100, and the sowing mechanism 100 rotates to sow the materials.

[0049] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of the spreading mechanism provided in the embodiment of the present application. Figures 1 to 3 As shown, in an optional embodiment, the spreading mechanism 100 may include a driving member 110, a connecting shaft 120, and a spinning disc assembly 130. The spinning disc assembly 130 may maintain unidirectional rotation during operation.

[0050] The driving member 110 is connected to the connecting shaft 120 by transmission, and is used to drive the connecting shaft 120 to rotate, and the connecting shaft 120 is connected to the disk assembly 130 by transmission. The driving member 110 can be selected as a driving motor. During the sowing operation, the driving member 110 drives the connecting shaft 120 to rotate, and the connecting shaft 120 drives the disk assembly 130 to rotate, and the disk assembly 130 spreads the materials dropped from the material box 200. Optionally, the disk assembly 130 can include a disk 131 that rotates in one direction. The disk 131 is connected to the connecting shaft 120 by transmission, and during the operation, the disk 131 rotates with the connecting shaft 120 as the axis. The disk 131 can be optionally a disc-shaped structure. The disk 131 has a first surface and a second surface that are arranged opposite to each other. The first surface is a side surface that contacts the material when sowing the material. In addition, the disk 131 is not limited to a single disk, and can also be a double disk or more disks.

[0051] Optionally, the spinning plate 131 is horizontally arranged below the material box 200, or the spinning plate 131 is vertically arranged on one side of the material box 200. In this embodiment, the spinning plate 131 is horizontally arranged below the material box 200, and the spinning plate 131 can receive the material dropped from the material box 200 so as to spread the material.

[0052] Optionally, in order to hit and spread the material when spreading it, the disk assembly 130 may further include a paddle 132. The paddle 132 is disposed on the first surface and is used to paddle the material to spread it. Optionally, the paddle 132 is eccentrically disposed on the first surface. The paddle 132 is generally a sheet-like structure, and its shape is not specifically limited, for example, it may be a rectangular shape. The paddle 132 may be disposed perpendicular to the first surface. In addition, there may be a plurality of paddles 132, and the plurality of paddles 132 are disposed symmetrically about the center of the disk 131.

[0053] Optionally, in the embodiment of the present application, the spinning tray 131 may be in a vertical state.

[0054] In addition, in some further optional embodiments of the present application, based on any of the above embodiments, the difference is that the spreading mechanism 100 further includes a spinner cover 133, and the spreading system further includes an auger conveying device 400. For other matters not mentioned, please refer to the previous embodiments.

[0055] Among them, the disc cover 133 is connected to the auger conveying device 400, the driving member 110 is installed on the outside of the disc cover 133, the disc assembly 130 is arranged in the disc cover 133, and the end of the connecting shaft 120 away from the driving member 110 extends into the disc cover 133 and is transmission-connected to the disc assembly 130; the auger conveying device 400 is connected to the material box 200, and is used to transport the material in the material box 200 to the disc assembly 130 for sowing.

[0056] Optionally, the auger conveying device 400 may include an auger housing and an auger. The auger housing is located at the bottom of the material box 200 and is connected to the material box 200. The auger is rotatably arranged in the auger housing, and the auger housing is connected to the disk cover 133. When spreading materials, the materials enter the auger housing from the material box 200, and the auger rotates to transport the materials to the disk assembly 130, and the paddle 132 on the disk 131 hits the spreading materials.

[0057] like Figure 1 and Figure 2 The sowing system shown in the figure adopts a double-auger double-spinner structure, which has a high cost. In order to reduce the cost, the present application embodiment provides an optional implementation method, in which the sowing mechanism 100 in the sowing system adopts a single-auger single-spinner structure. Please refer to Figure 4 and Figure 5 , Figure 4 The third structural diagram of the spreading system provided in the embodiment of the present application is as follows: Figure 5 This is the fourth structural schematic diagram of the spreading system provided in the embodiment of the present application. Figure 4 and Figure 5 The structure shown is Figure 1 , Figure 2The difference between the structures shown is that the number of the spinning disc assembly 130 in the spreading mechanism 100 is 1, and the number of the auger conveying device 400 is 1, that is, it is a single auger and single spinning disc structure, and the rest of the structures are the same and will not be described in detail here.

[0058] but Figure 4 and Figure 5 When the spreading system shown is in operation, since the spinner 131 rotates unidirectionally and the auger conveying device 400 cannot convey all materials to the center of the spinner 131, the sowing width is asymmetric relative to the drone. Even if the auger conveying device 400 conveys all materials to the center of the spinner 131, the sowing width is still asymmetric. For details, please refer to Figure 6 , Figure 6 A schematic diagram of a sowing width boundary provided in an embodiment of the present application.

[0059] like Figure 6 As shown, the flight direction of the drone is towards Figure 6 In the paper, the spinning disc 131 rotates clockwise, and the material is beaten and thrown out by the paddle 132 of the spinning disc 131. The sowing amplitude R on the right side of the drone is obviously smaller than the sowing amplitude L on the left side of the drone, and there is a problem of asymmetric sowing amplitude. It should be noted that Figure 6 The sowing width boundary shown is only one possibility. The spinning disc 131 can also rotate counterclockwise. There is also a situation where the sowing width R on the right side of the drone is significantly larger than the sowing width L on the left side of the drone.

[0060] It should be noted that Figure 6 The shown sowing width (also called spreading width) can be used as a working width. Figure 6 The problem of asymmetric sowing width shown is the problem of asymmetric working width.

[0061] In order to overcome the impact of the asymmetric operation range on the operation, the embodiment of the present application provides a route planning method for a drone to plan the target route of the drone during operation. When the drone moves along the target route to perform the operation, in the case of asymmetric operation range, the impact can be overcome to achieve full coverage of the operation area. The route planning method for a drone can be applied to, but is not limited to, the electronic devices described below.

[0062] The present application embodiment provides an electronic device, which may be a central control unit of a drone, a control terminal of a drone, a mobile phone, a computer, a server, or other devices. Figure 7 , a schematic diagram of the structure of an electronic device. The electronic device includes a processor 10, a memory 11, and a bus 12. The processor 10 and the memory 11 are connected via the bus 12, and the processor 10 is used to execute an executable module stored in the memory 11, such as a computer program.

[0063] The processor 10 can be an integrated circuit chip with signal processing capabilities. In the implementation process, each step of the route planning method of the drone can be completed by the hardware integrated logic circuit in the processor 10 or the instructions in the form of software. The above-mentioned processor 10 can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components.

[0064] The memory 11 may include a high-speed random access memory (RAM), and may also include a non-volatile memory, such as at least one disk memory.

[0065] The bus 12 may be an ISA (Industry Standard Architecture) bus, a PCI (Peripheral Component Interconnect) bus, or an EISA (Extended Industry Standard Architecture) bus. Figure 7 Although only one bidirectional arrow is used in the figure, it does not mean that there is only one bus 12 or only one type of bus 12 .

[0066] The memory 11 is used to store programs, such as programs corresponding to the route planning device of the drone. The route planning device of the drone includes at least one software function module that can be stored in the memory 11 in the form of software or firmware or fixed in the operating system (OS) of the electronic device. After receiving the execution instruction, the processor 10 executes the program to implement the route planning method of the drone.

[0067] Optionally, the electronic device provided in the embodiment of the present application further includes a communication interface 13. The communication interface 13 is connected to the processor 10 via a bus. When the electronic device is not the central control unit of the mobile platform, the electronic device can be connected to the central control unit of the drone via the communication interface to push the obtained target route to the central control unit of the mobile platform.

[0068] It should be understood that Figure 7 The structure shown is only a schematic diagram of a portion of the electronic device. The electronic device may also include Figure 7 More or fewer components as shown, or with Figure 7 Different configurations shown. Figure 7 Each component shown in the figure can be implemented by hardware, software or a combination thereof.

[0069] The embodiment of the present application provides a route planning method for a drone, which is used to plan and obtain a target route for the drone. The drone is equipped with an execution system, which is used to maintain the target altitude and perform a sowing operation along the forward direction, and the left and right operating ranges are different. The left and right sides are defined relative to the forward direction of the drone (for example, the flight direction of the drone). The execution system can be, but is not limited to, a sowing system. The route planning method for the drone can be, but is not limited to, applied to Figure 7 For detailed procedures, please refer to the electronic equipment shown in Figure 8 ,The route planning method of the UAV includes : S102 and S103 , which are described in detail as follows.

[0070] S102, planning the operation area based on the total operation range of the execution system to obtain an initial straight line route.

[0071] Among them, the interval between any two adjacent initial straight routes is equal to the total operating range, and the total operating range is the sum of the left operating range and the right operating range.

[0072] In the present application, when the execution system is a spreading system, the left operating range is the left spreading range, and the right operating range is the right spreading range.

[0073] Please refer to Fig. 9 , Fig. 9 The schematic diagram of the initial straight line route provided in the embodiment of the present application, wherein the interval between any two adjacent initial straight line routes is equal to the total operation range, that is, (L+R), where L represents the left operation range and R represents the right operation range.

[0074] Because the operating range on the left is asymmetric with that on the right, that is, L is not equal to R, operating according to the initial straight line may not fully cover the operating area. Figure 6As shown, the spreading range R on the right side of the drone is obviously smaller than the spreading range L on the left side of the drone. If the drone (such as a drone) directly drives (or flies) along the initial straight line and simultaneously carries out the spreading operation, then a large overlapping area will appear on the left side of the initial straight line, and a large blank area (an area not operated, which can also be understood as a missed spraying area or a missed sowing area) will appear on the right side, and the operation area cannot be fully covered, affecting the operation effect.

[0075] It should be noted that when the sowing range R on the right side of the drone is significantly greater than the sowing range L on the left side of the drone, there will also be large overlapping areas and blank areas, and the same problem exists, which will not be elaborated here.

[0076] In order to fully cover the operation area and ensure the operation effect, subsequent steps need to be carried out.

[0077] S103, offsetting the initial straight line route toward the target direction by a preset distance to obtain a corrected target route.

[0078] Among them, when the left operating range is larger than the right operating range, the target direction is the right direction relative to the forward direction; when the left operating range is smaller than the right operating range, the target direction is the left direction relative to the forward direction.

[0079] For example Figure 6 In the case where the right-hand spreading range R of the drone is significantly smaller than the left-hand spreading range L of the drone, the target direction is the right direction relative to the forward direction. Fig.10 , Fig.10 A schematic diagram of a target route when the target direction provided in an embodiment of the present application is the right direction relative to the forward direction. Fig.10 Before the mid-shift (dashed line) Fig. 9 The initial straight line route in the figure corresponds to the corrected target route after deviation.

[0080] In the present application, the intervals between the revised target routes are no longer a fixed total operating range (L+R), and the intervals are alternately 2L or 2R.

[0081] It should be noted that when the drone performs the sowing operation along the corrected target route, because it has been offset by the preset distance to the side with a shorter operating range, the blank area on the side with a shorter operating range can be reduced, and the repeated area on the side with a wider operating range can be reduced. When the preset distance is appropriate, full coverage can be achieved without duplication. If the drone (such as a UAV) directly drives (or flies) along the corrected target route and simultaneously carries out the sowing operation. There will be no overlapping areas and blank areas, and the operating area will be fully covered to ensure the operating effect.

[0082] In summary, the embodiment of the present application provides a route planning method for a drone, wherein the drone is deployed with an execution system, the execution system is used to perform a sowing operation along the forward direction, and the left operation amplitude is not equal to the right operation amplitude, and the route planning method for the drone includes: planning the operation area based on the total operation amplitude of the execution system to obtain an initial straight line route; wherein the interval between any two adjacent initial straight line routes is equal to the total operation amplitude, and the total operation amplitude is the sum of the left operation amplitude and the right operation amplitude; offsetting the initial straight line route to the target direction by a preset distance to obtain a corrected target route; wherein, when the left operation amplitude is greater than the right operation amplitude, the target direction is the right direction relative to the forward direction, and when the left operation amplitude is less than the right operation amplitude, the target direction is the left direction relative to the forward direction. The drone directly drives along the corrected target route and simultaneously carries out the sowing operation. There will be no overlapping areas and blank areas, and the operation area will be fully covered to ensure the operation effect.
