Method and device for generating all-region-covering optimal working path for farmland plot

Abstract

The invention discloses a method and device for generating an all-region-covering optimal working path for a farmland plot. The method comprises the following steps of: forming headland turning modes such as a semicircular turning mode, a pear-shaped turning mode, a fish-tail-shaped turning mode and the like by considering the working requirements of tractor units of different types and scales inconsistence with the practical requirement of agricultural machinery operating management; putting forward a plurality of working path optimization standards of the tractor units to realize optimization targets such as minimum turning, lowest turning working consumption, a shortest working path, an optimal effective working path ratio and the like; establishing an optimal working direction search method and a working path generating algorithm of the tractor units on the basis of priori information such as a working plot vector, a working unit parameter, a path optimization target and the like to realize all-region-covering of the farmland plot; and integrating embedded hardware devices of functional modules such as a storage module, an input module, an output module, auxiliary equipment and the like to realize planning, calculating, displaying and introducing of the all-region-covering optimal working path for the farmland plot and recording, storing and displaying the practical working path of each tractor unit.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method and device for generating an optimal operation path covering the entire area of ​​farmland plots. Background technique [0002] During the field operation of the tractor unit, the operators design the field operation path based on experience and some common-sense rules, and there are problems such as heavy tillage, missing tillage, and excessive travel, which affect the production efficiency of the operation. The use of tractor automatic driving technology can effectively reduce the overlap and omission between adjacent operation lines, and is an important technical means to improve the quality and efficiency of farmland operations and reduce operation costs. For the tractor automatic driving system, a clear field operation path must be given as the navigation tracking target input by the system in order to carry out normal walking and operation, especially for fie...
