Problems solved by technology

[0002] Ordinary pruning and creative pruning of lawns play an important role in the beautification of parks and scenic spots. In urban and scenic greening, lawns occupy a large green area, and subsequent maintenance requires a lot of manpower. At present, ordinary pruning and creative pruning of lawns mostly rely on manual work. There is a huge demand for lawn automatic creative trimming devices and technologies in the market. Ordinary lawn trimming is a mechanical action, and lawn pattern trimming is a complicated process without error tolerance.

Embodiment Construction

[0040] The following uses a symmetrical two-axis mowing device N=2 (width W=30cm, pattern resolution side length D=15cm) and three levels of mowing height (h 1 =4cm,h 2 =8cm,h 3 = 12cm) as an example, the principles and features of the present invention will be described in conjunction with the accompanying drawings. The examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0041] like figure 1 Shown, a kind of automatic landscape mowing method comprises the following steps:

[0042] like figure 2 As shown, step 1, determine the rectangular lawn to be trimmed, obtain the boundary information of the lawn plot, and obtain the closed plot boundary information P1;

[0043] like image 3As shown, step 2, set the desired landscape pattern, draw its external closed outline, and initially obtain the pattern boundary information P2 to be trimmed;

[0044] like Figure 4 As shown, in step 3, match the p...

Abstract

The present invention relates to an automatic landscape mowing method and device. The method comprises the following steps: 1. Determine the boundary P3 to be trimmed; The width is the side length, and the closed areas in P3 are synchronously rasterized to obtain the mowing height and center point coordinates corresponding to each grid; 3. The number of mowing units of the mowing device is the grouping capacity, and then " "Group" traverses each grid of P3, and stores the mowing height and coordinate information corresponding to each group of grids as instructions in order to obtain the mowing instruction sequence information P4. 4. The mowing device automatically traverses the actual lawn in groups according to P4, The lawn is trimmed according to the mowing height corresponding to the instruction, and the target landscape pattern can be obtained. The invention is suitable for multi-axis or single-axis cutting knives, the rotating speed and height of each cutting knife are independently controlled, the trimming precision is high, and the mowing efficiency is high.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an automatic landscape mowing method and device. Background technique [0002] Ordinary pruning and creative pruning of lawns play an important role in the beautification of parks and scenic spots. In the greening of cities and scenic spots, lawns occupy a large green area, and subsequent maintenance requires a lot of manpower. There is a huge demand for lawn automatic creative trimming devices and technologies in the market. Ordinary lawn trimming is a mechanical action, and lawn pattern trimming is a complicated process without error tolerance. Combining modern agricultural path planning, computer-aided design and GPS positioning technology, using the height contrast of the mowing height to present creative patterns, realizing an automatic landscape mowing device that integrates ordinary pruning and creative pruning. Styling technology is of great significance to improve ...
