Problems solved by technology

In terms of the mechanical structure of plant protection drones, most plant protection drones have fixed mechanical structures, which will bring many obstacles in the actual transportation process. To face the transportation problem, there is a multi-rotor plant protection drone and horizontal folding arms. It adopts horizontal The way of folding the arms can reduce the space occupied by the plant protection machine, but the space occupation is still relatively large, and there will still be big problems when transporting multiple plant protection machines

Embodiment 1

[0043] like Figure 6 As shown, firstly, the GmapPolygon class in GMap.NET is used to display the selected area. The method of use is similar to that of GMapMarker. The geographical coordinates of the polygonal farmland plots to be operated are obtained in turn, and an irregular quadrilateral of the plots is formed on the map. Plant protection The aircraft flies to each point of the polygon in turn, and obtains the latitude and longitude through the GetPointList method. First create a new overlay and GMapPolygon, and then define a list. The generic type of this list is PointLatLng. PointLatLng is used to store the latitude and longitude point class transmitted by the plant protection drone. Create an area through these points, and then use the SolidBrush brush The class performs operations such as filling color on this area, and finally adds GMapPolygon to Overlay, and adds Overlay to MapControl, such as Figure 7 As shown, an irregular quadrilateral is formed on the map;...

Embodiment 2

[0046] First, the GmapPolygon class in GMap.NET is used to display the selected area. The method of use is similar to that of GMapMarker. The geographic coordinates of the polygonal farmland plots to be operated are obtained in turn, and an irregular pentagon of the plot is formed on the map. The plant protection machine Fly to each point of the polygon in turn, and obtain the latitude and longitude through the GetPointList method. First create a new overlay and GMapPolygon, and then define a list. The generic type of this list is PointLatLng. PointLatLng is used to store the latitude and longitude point class transmitted by the plant protection drone. Create an area through these points, and then use the SolidBrush brush The class performs operations such as filling color on this area, and finally adds GMapPolygon to Overlay, and adds Overlay to MapControl, such as Figure 9 As shown, an irregular pentagon is formed on the map;

Abstract

The invention relates to a plant protection aircraft for executing agricultural automatic spraying tasks. The plant protection aircraft comprises a frame, a foldable cantilever mechanism, an undercarriage, a spraying device, a lithium battery pack, a power mechanism and a flight control system and is characterized in that the liquid pesticides of the spraying rods of the plant protection aircraftare controlled by controlling receiver signals, and an electronic switch controls the on and off of a pressurizing pump through the electric signals. A method for planning the field route of the plantprotection aircraft mainly includes the steps of firstly, using the plant protection aircraft to sequentially acquire the geographic coordinates of to-be-operated polygonal field parcels, and generating field parcel shapes in a ground station; secondly, designing a route planning algorithm for irregular polygons formed on a map, and performing automatic field planting to generate the flight trajectory of the plant protection aircraft. The plant protection aircraft has the advantages that the arms of the plant protection aircraft are foldable, spraying tasks can be completed automatically, andthe spraying precision of various irregular parcels is increased.

Description

technical field [0001] The invention belongs to the field of agricultural plant protection, and in particular relates to a plant protection machine and a plant protection path planning method. Background technique [0002] Plant protection drones can realize automatic quantification of pesticides, precise control, and ultra-low-volume spraying. pollution and improve the quality and safety of agricultural products. [0003] Compared with manual spraying, the operation of plant protection drones is 40 times that of manual operations, especially in the process of large-scale and sudden pest control. It is irreplaceable and can effectively alleviate the rural labor force brought about by urbanization. Insufficient problem. [0004] The plant protection UAV is operated by remote control on the ground, but this traditional manual operation will cause the danger of bombing due to the operator's error. In order to improve the safety of plant protection operations and improve the e...
