Intelligent mower based on laser scanning radar sensor and control method of intelligent mower

Abstract

The invention discloses an intelligent mower based on a laser scanning radar sensor and a control method of the intelligent mower. The intelligent mower comprises a mobile cart body, an image collection device, a steering mechanism, a driving mechanism, the laser scanning radar sensor, a controller, a cutting motor and a height adjustment mechanism; a cutting line is installed on an output shaft of the cutting motor through a transmission device; the height adjustment mechanism is arranged on the mobile cart body, and the cutting motor is arranged on the height adjustment mechanism; the signaloutput end of the image collection device and the signal output end of the laser scanning radar sensor are connected with the signal input end of the controller separately, and the signal output endof the controller is connected with the steering mechanism, the driving mechanism, the cutting motor and the height adjustment mechanism separately. According to the intelligent mower, the height of ato-be-cut lawn can be precisely distinguished through the laser scanning radar sensor, the mowing height can be adjusted according to demands, and the intelligent mower has high mowing quality.

Description

technical field [0001] The invention belongs to the technical field of intelligent lawnmowers, in particular to an intelligent lawnmower based on a laser scanning radar sensor and a control method thereof. Background technique [0002] Most of the existing lawn mowers are manual, and the height of the trimmed lawns is uneven, and it is time-consuming and labor-intensive. At present, most of the existing intelligent lawn mowers on the market are ultrasonic guidance. Although ultrasonic guidance can also identify obstacles ahead, it cannot accurately distinguish the height of the grass to be mowed, nor can it adjust the trimming height according to user needs. At the same time, ultrasonic guidance cannot Accurately grasping the overall lawn specifications cannot meet the needs of today's market. In addition, the existing smart lawn mowers do not control the mowing quality, but focus more on path planning and obstacle recognition. The mowing quality of the smart lawn mower wil...

[0002] Most of the existing lawn mowers are manual, and the height of the lawn trimmed is uneven, and it is time-consuming and labor-intensive

At present, most of the existing intelligent lawn mowers on the market are ultrasonic guidance. Although ultrasonic guidance can also identify obstacles ahead, it cannot accurately distinguish the height of the grass to be mowed, nor can it adjust the trimming height according to user needs. At the same time, ultrasonic guidance cannot Accurately grasping the overall lawn specifications cannot meet today's market demand

In addition, the existing smart lawn mowers do not control the mowing quality, but focus more on path planning and obstacle recognition. The mowing quality of the smart lawn mower will be affected by the driving speed, cutting speed Due to the influence of factors such as mowing depth and mowing depth, the driving speed of the existing intelligent lawn mower cannot be adjusted according to the height of the lawn. Drag, which affects the speed stability of the mower, especially on highly complex lawns

Existing intelligent lawn mowers do not adjust any driving speed and cutting speed for this phenomenon, resulting in low mowing quality
