Operation vehicle travel deflection detection and adjustment method and system

Abstract

The invention relates to the technical field of agricultural machine intelligentization and provides an operation vehicle travel deflection detection and adjustment method and system. The method includes the following steps that the navigation driving state of an operation vehicle navigation assisting automatic driving system is detected; when the automatic driving system is in a navigation pause driving state, the current travel deflection amount of an operation vehicle is calculated according to positioned coordinates of the current position and an original operation target track of the operation vehicle, and then the operation target track of the operation vehicle is calculated and planned again; and when the operation vehicle navigation assisting automatic driving system is restarted, operation navigation is conducted according to the operation target track which is calculated and planned again. Therefore, the travel deflection adjustment operation steps of a user are simplified, the operation efficiency is improved, and the functions of an original operation vehicle navigation assisting automatic driving system are completed.

Description

technical field [0001] The invention belongs to the technical field of intelligent agricultural machinery, and in particular relates to a method and system for detecting and adjusting the deviation of a working vehicle. Background technique [0002] As agricultural operations become more and more large-scale, the intelligent level of agricultural machinery is also gradually improving. In order to reduce labor intensity and improve operation efficiency and quality, in recent years, navigation-assisted automatic driving systems have begun to be widely promoted on operating vehicles. and apply. [0003] The navigation-assisted automatic driving system includes two parts: a base station and a mobile terminal, and the mobile terminal is composed of a GNSS positioning unit, a remote communication unit, a body attitude detection unit, a steering angle detection unit, a control unit and a human-computer interaction unit. With the help of the navigation-assisted automatic driving sy...

Problems solved by technology

[0005] (1) The operator gets off the car and uses a ruler to measure the offset, and then enters the offset value through the display operation interface, and then continues the automatic driving operation. The automatic driving system completes the line offset adjustment after a period of time and distance adjustment, and starts When working on a new track, the adjustment process of the line offset is complicated, and the user needs to clearly understand whether it is shifted to the left or right relative to the first line of the job, and the user needs to manually measure the operation, which is relatively difficult and inefficient;

[0006] (2) The user visually estimates the offset that needs to be adjusted, and tries to adjust it gradually until the new operation track meets the demand. The offset adjustment process of this row is complicated, and the trial and error is not accurate, resulting in repeated adjustments;

[0007] (3) Re-calibrate the coordinates of the starting point and end point of the work plot, and re-plan the route. The adjustment process of the line offset is complicated and takes longer, which greatly reduces the working efficiency
