The five electronic speed controllers are respectively used to control five motors on the sowing device and the spraying device. In this layout where one electronic speed governor controls one motor, the integration degree of the electronic speed governor is not high, which not only occupies the volume of the unmanned aerial vehicle, increases the weight of the unmanned aerial vehicle, but also increases the production cost of the unmanned aerial vehicle, resulting in troublesome wiring and complex structure.

[0024] With the rapid development of the low-altitude economy, plant protection UAVs have been widely used in the field of agricultural planting. They can carry out sowing operations on farmland by carrying a sowing device or carry out pesticide spraying operations by carrying a spraying device.
[0025] Currently, five electronic speed controllers are usually arranged on the plant protection UAVs on the market. The five electronic speed controllers are respectively used to control the five motors on the sowing device and the spraying device. In this layout where one electronic speed controller controls one motor, the integration level of the electronic speed controller is not high. It not only occupies the volume of the UAV, increases the weight of the UAV, but also increases the production cost of the UAV, resulting in troublesome wiring and complex structure.
[0026] To solve the above technical problems, this embodiment provides an integrated control device applied to a plant protection UAV.
[0027] See Figures 1-5 , this embodiment includes a plant protection UAV 1. A signal box 2 is fixed on the fuselage frame in the nose direction of the plant protection UAV 1. Three electronic speed controllers 3 are integrated inside the signal box 2, and the three electronic speed controllers 3 are used to control the operation of the motors.
[0028] Specifically, the electronic speed controller 3 can send corresponding motor drive signals to the motor according to the control logic, so as to drive the motor to operate.
[0029] In this embodiment, the plant protection UAV 1 has a sowing mode and a spraying mode. The maximum number of motors operating in the sowing mode is two, and the maximum number of motors operating in the spraying mode is three.
[0030] Specifically, the motors in the spreading mode include a feeding motor 7 and a throwing disc motor 8, and the motors in the spraying mode include a water pump motor 9, a first centrifugal motor 10, and a second centrifugal motor 11.
[0031] In the prior art, usually five electronic speed controllers 3 are adopted to separately control the feeding motor 7, the throwing disc motor 8, the water pump motor 9, the first centrifugal motor 10, and the second centrifugal motor 11, which results in the conventional unmanned aerial vehicle being not superior in terms of volume, weight, and cost, and is not conducive to the cost performance of the unmanned aerial vehicle for consumption.
[0032] In this embodiment, the signal box 2 includes a housing 4, and an HUB board 5 is installed on the housing 4. A receiving space for installing the three electronic speed controllers 3 is formed by enclosing between the housing 4 and the HUB board 5.
[0033] Specifically, a plurality of signal terminals 6 are installed on the HUB board 5.
[0034] In this embodiment, the three electronic speed controllers 3 are respectively used to control the operation of two motors in the spreading mode or to control the operation of three motors in the spraying mode.
[0035] Specifically, referring again to Figures 4-5 , in the spreading mode, the plant protection unmanned aerial vehicle 1 is equipped with a spreading device. At this time, two of the three electronic speed controllers 3 control the operation of the feeding motor 7 and the throwing disc motor 8.
[0036] In the spraying mode, the plant protection unmanned aerial vehicle 1 is equipped with a spraying device. At this time, the three electronic speed controllers 3 respectively control the operation of the water pump motor 9, the first centrifugal motor 10, and the second centrifugal motor 11.
[0037] The integrated control device for a plant protection unmanned aerial vehicle provided in this embodiment only needs to integrate three electronic speed controllers 3 to be used to control the operation of the feeding motor 7 and the throwing disc motor 8 in the spreading mode, or to control the operation of the water pump motor 9, the first centrifugal motor 10, and the second centrifugal motor 11 in the spraying mode, reducing the number of electronic speed controllers 3 required for the plant protection unmanned aerial vehicle 1 and improving the integration degree of the electronic speed controllers 3.
[0038] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.
