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 invention relates to an automatic landscape mowing method and device. The method comprises the following steps of 1, determining a boundary P3 to be trimmed; 2, determining the lawn height corresponding to each independent closed area in the P3, and performing synchronous griding processing on each closed area in the P3 by taking the working breadth of a mowing unit of the mowing device as theside length to obtain the mowing height and the center point coordinate corresponding to each grid; 3, using the number of mowing units of the mowing device as grouping capacity, traversing all gridsin the P3 in groups in sequence, using the mowing height and coordinate information corresponding to each group of grids as instructions to be stored in sequence, and obtaining mowing instruction sequence information P4; and 4, automatically and sequentially traversing the actual lawn in groups according to the P4 by the mowing device, trimming the lawn according to the mowing height corresponding to the instruction, so as to obtain a target landscape pattern. The mowing device is suitable for multi-shaft or single-shaft cutters, the rotating speed and the height of each cutter are independently controlled, the mowing 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 ...
