Embodiment 1

[0019] see figure 1 , the present embodiment provides a parallel cutting method combining the satellite navigation of the lawnmower and the fence.

[0020] Set perimeter line 1 at the boundary of the designated mowing area, perimeter line 1 can be a physical obstacle, or conduct electronic induction with the mower, so as to limit the lawn mower to mowing within the range of perimeter line 1, thereby limiting mowing mowing range of the machine.

[0021] The lawn mower has a built-in gyroscope. Before mowing the lawn, let the lawn mower walk a circle along the perimeter 1 to obtain GNSS heading information, thereby initializing the heading angle of the gyroscope.

[0022] Then use the acquired GNSS information to partition the mowing area.

[0023] Afterwards, the lawn mower can mow grass separately in each partition. The specific method of mowing grass is the parallel mowing method. Make the angle between adjacent mowing paths 0° or 180°, so as to make the mowing path of the...

Embodiment 2

[0030] see figure 2 , the difference between this embodiment and embodiment 1 is that the two straight lines are respectively parallel to the two sides of the rectangle 2, and the rectangle 2 is divided into four congruent partitions at this time. Use the same method for secondary partitioning for each partition. For example, the rectangular partition in the lower left corner is divided into four congruent secondary rectangular partitions 3 by two mutually perpendicular straight lines, and the parallel mowing method can be applied in the four secondary rectangular partitions 3 for mowing. The advantage of this method is that the mowing coverage at the edge of the perimeter line 1 can be guaranteed to the greatest extent.

Abstract

The invention discloses a satellite navigation and surrounding line combined parallel cutting method of a mower, which comprises the following steps: setting a surrounding line at the boundary of a specified mowing area, and limiting the mowing range of the mower through the surrounding line; a mower adopts a parallel mowing method in a mowing range limited by the surrounding line; a gyroscope isarranged in the mower, and drifting of the gyroscope is corrected through a GNSS so as to guarantee the advancing direction of the mower. An inclination angle sensor is further arranged in the mower and electrically connected to a driving device of the mower, and the driving device corrects output power according to data transmitted by the inclination angle sensor. When the mower linearly moves for a long distance, the route deviates; when deviation occurs, the mower certainly topples over to a certain extent due to errors of an internal control system, so that the gyroscope is used for detection, the inclination angle is sent to the GNSS, the GNSS controls a driving device of the mower to perform route correction, and the automatic stable effect of the mowing course is guaranteed.

Description

【Technical field】 [0001] The invention relates to a parallel cutting method combining satellite navigation and perimeter lines of a lawnmower, belonging to the field of lawnmowers. 【Background technique】 [0002] At present, the working method of the wire mower is basically based on random mowing, and the mulching efficiency is low. There are a small number of lawn mowers that improve mowing efficiency through parallel mowing, but the parallel mowing method is difficult for the mower to control, and it is difficult to maintain a stable heading in the case of complex terrain. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a parallel cutting method combining satellite navigation and perimeter lines of a lawn mower with better mowing stability and higher coverage. [0004] To solve the above technical problems, the present invention adopts the following technical solutio...
