Embodiment 1

[0040] refer to figure 1 and figure 2 , the method for preventing fixed-point mowing from wearing out the grass in this embodiment is applied to an automatic lawn mower, which does not require manual control, can automatically perform route planning, and automatically complete the mowing operation. This process can refer to the prior art. The mower includes independently controlled first drive wheels and second drive wheels, so that the rotation of the first drive wheels and the second drive wheels can be independently controlled respectively, and the speeds of the first drive wheels and the second drive wheels can be the same , can also be different. Alternatively, the first drive wheel and the second drive wheel are of the same size. Concretely, the method for preventing fixed-point mowing from wearing away the grass includes the following steps:

[0041] S1. Receive a fixed-point mowing instruction.

[0042] Specifically, the fixed-point mowing command is used to make ...

Embodiment 2

[0050] refer to image 3, On the basis of Embodiment 1, in the method for preventing fixed-point mowing of the present embodiment from wearing out the grassland, executing the fixed-point mowing instruction in step S2 to perform the mowing operation includes:

[0051] S21. Select a fixed-point mowing radius.

[0052] Specifically, in order to realize fixed-point mowing, the first driving wheel and the second driving wheel of the mower need to rotate simultaneously, and the first driving track of the first driving wheel and the second driving track of the second driving wheel are concentric circles, It is first necessary to determine the fixed-point mowing radius. The fixed-point mowing radius is used to characterize the size of the circular trajectory formed by the overall driving trajectory of the lawn mower. However, due to the large volume of the lawn mower, the radius of the circular trajectory formed during driving at any point on the lawn mower can be used as the fixed-...

Embodiment 3

[0063] On the basis of Embodiment 2, step S22 in the method for preventing fixed-point mowing from wearing out the grass in this embodiment includes: obtaining the first rotational speed of the first driving wheel corresponding to the fixed-point mowing radius and the second driving wheel according to the first corresponding relationship The second rotation speed of the first driving wheel and the second number of rotations of the second driving wheel are obtained according to the second corresponding relationship; wherein, the first corresponding relationship is the first driving wheel and the second driving wheel under the same fixed-point mowing radius The rotational speed of the two driving wheels, the second corresponding relationship is the number of rotations required by the first driving wheel and the second driving wheel to mow grass at least one circle under the same fixed-point mowing radius.

[0064] It can be understood that after determining the mowing radius of t...

Abstract

The invention relates to a method for preventing fixed-point mowing from wearing away grassland. The method is applied to a robotic lawn mower comprising independently controlled first and second drive wheels. The method includes: S1. Receive a fixed-point mowing instruction; S2. Execute the fixed-point mowing instruction to mow the grass. The first driving track of the first driving wheel and the second driving track of the second driving wheel are concentric circles. In the fixed-point mowing operation of the lawnmower in the present invention, the first driving wheel and the second driving wheel rotate simultaneously to form concentric circle tracks, thereby effectively avoiding wear on the lawn.

Description

technical field [0001] The invention relates to the field of lawnmowers, and more specifically, relates to a method for preventing fixed-point mowing from wearing out grasslands and an automatic lawnmower. Background technique [0002] The automatic lawn mower does not need manual control, it can automatically plan the route and complete the mowing operation automatically. During the operation of the lawn mower, there will be a fixed-point mowing action, that is, the lawn mower rotates in a small area to complete the mowing in the small area. In the prior art, when the lawn mower mows at a fixed point, only one of the two drive wheels rotates, and the other drive wheel remains stationary at one point, so that the rotating drive wheel drives The wheel is the center to form a circular mowing area to realize fixed-point mowing. But the driving wheel that keeps motionless in this fixed-point mowing mode is to constantly wear the turf, causing damage to the lawn. Contents of ...
