1. A control method of an agricultural unmanned aerial vehicle is characterized in that the agricultural unmanned aerial vehicle is provided with a plurality of spray heads, each spray head is located at different positions of the agricultural unmanned aerial vehicle, the agricultural unmanned aerial vehicle is controlled by a ground control end, and the ground control end is provided with a user interface, the method comprises the following steps:

  • acquiring control information input by a user on the user interface, wherein when the control information comprises the flight speed control information of uniform flight, the flight altitude control information of ground-imitating flight, the spray head control information of uniform spraying and the radar height setting function is started;

    determining operation parameters of the agricultural unmanned aerial vehicle according to the control information;

    controlling the agricultural unmanned aerial vehicle to adjust the flying height of the agricultural unmanned aerial vehicle in real time according to the detection result of the radar so as to keep the height of the agricultural unmanned aerial vehicle relative to crops, and simultaneously flying at a constant speed and spraying at a constant speed;

    the control information includes;

    spraying flow control information, spraying direction control information, flying speed control information, flying height control information, nozzle control information, air route spacing control information and safety distance control information;

    wherein the safe distance is used to avoid the agricultural unmanned aerial vehicle spraying a spray outside an agricultural unmanned aerial vehicle operating area;

    the user interface includes at least one of;

    a target area for identifying the agricultural unmanned aerial vehicle operating area;

    a target line segment for identifying a flight path of the agricultural unmanned aerial vehicle;

    a movable marker for identifying a heading of the agricultural unmanned aerial vehicle;

    the first marking point is used for identifying a first position of the agricultural unmanned aerial vehicle, and the second marking point is used for identifying a second position of the agricultural unmanned aerial vehicle;

    the acquiring of the spraying direction control information input by the user on the user interface includes;

    acquiring spraying direction control information input by a user on the user interface through rotating the target area;

    alternatively, the first and second electrodes may be,acquiring spraying direction control information input by a user on the user interface through rotating the target line segment;

    alternatively, the first and second electrodes may be,acquiring spraying direction control information input by a user on the user interface by controlling the direction of the movable mark;

    alternatively, the first and second electrodes may be,acquiring spraying direction control information input by a user on the user interface by clicking the left side or the right side of a connecting line between the first mark point and the second mark point;

    alternatively, the first and second electrodes may be,and acquiring spraying direction control information input by a user through the operation on the first mark point and the second mark point on the user interface.
