DGPS (differential global positioning system)-based automatic tracking electric mower

Abstract

The invention discloses a DGPS (differential global positioning system)-based automatic tracking electric mower, which comprises a mower body, a DGPS base station, a DGPS mobile station, a single-chipmicrocomputer control module, a motor driving module, motors, a battery power supply module, universal wheels and a cutter disc. After being acquired through the DGPS base station mounted on a roof,correction quantity is sent to the DGPS mobile station on the mower in real time to correct measurement data of the mower, and centimeter-level GPS positioning accuracy is realized. After primary manual setting of an optimal mowing trail, path guidance is provided for the single-chip microcomputer control module according to DGPS centimeter-level position coordinates and orientation angle information, the motor driving module is controlled to drive the motors to enable the mower to move at a low speed along an optimal mowing trail to complete mowing operation, and the mower is automatically powered off after tracking is finished. By DGPS centimeter-level real-time high-precision positioning, the mower is controlled to move at the low speed along the optimal moving trail, automation of a weeding process is realized, weeding efficiency is improved, and labor cost is reduced.

Description

technical field [0001] The invention relates to the field of landscaping and lawn treatment and beautification equipment, in particular to an automatic tracking electric lawnmower based on differential GPS centimeter-level high-precision positioning. Background technique [0002] Modern people's requirements for a better living environment are increasing day by day, and green areas such as gardens and lawns have become an indispensable part of the city. The traditional method of trimming the lawn is manual trimming, or manually pushing the lawn mower to trim, which is time-consuming and labor-intensive, with high labor costs and low mowing efficiency; or the lawn is repaired by an advanced intelligent mower, which realizes automation and improves trimming efficiency , but smart lawn mowers require multi-sensor fusion, complex path judgment and planning algorithms, etc., and the high development costs lead to high prices and are difficult to popularize and apply.
