Embodiment Construction

[0016] In the following, the present invention will be further described in conjunction with the drawings and specific embodiments.

[0017] Such as figure 1 As shown, a Smart Heading-based agricultural machinery navigation entry device includes two GNSS antennas installed on the top of the agricultural machinery, a GNSS module connected to the GNSS antenna, and the GNSS module is connected to the controller of the agricultural machinery. The controller is also connected with a 3G antenna and a radio antenna. The agricultural machine in this embodiment may be a tractor.

[0018] The two GNSS antennas form an axisymmetric distribution with the central axis of the agricultural machine as the axis of symmetry. When the agricultural machine is not tilted, the path formed by the axis of symmetry along with the running of the agricultural machine coincides with the preset running path. The axis of symmetry may be the central axis of the agricultural machine. The navigation and c...

Abstract

The invention relates to a navigation device and method for enabling an agricultural machine to enter a preset path based on Smart Heading. The device comprises two GNSS antennas installed on the top of the agricultural machine and a GNSS module connected with the two GNSS antennas, wherein the GNSS module is connected with a controller of the agricultural machine; the two GNSS antennas are axially symmetrical with the central axis of the agricultural machine as the symmetry axis; the GNSS module is used for working out a heading angle according to signals of the GNSS antennas and working out a slant angle according to the signals of any one GNSS antenna, and outputs the heading angle and the slant angle to the controller; the slant angle is the included angle between the GNSS antennas and the horizontal plane; the controller is used for working out a modification value according to the slant angle, so that the preset running path and a real-time running path of the agricultural machine coincide according to the modification value, and the running direction of the agricultural machine is controlled through the heading angle. When the agricultural machine stops, the current slant and heading states of the agricultural machine can be obtained, and the agricultural machine can rapidly enter the preset path according to the slant and heading states.

Description

technical field [0001] The invention relates to agricultural machinery navigation technology. Background technique [0002] Global Positioning System (Global Position System, referred to as GPS) has the remarkable characteristics of all-weather, high precision, automation, etc., and provides a relatively mature positioning technology for geographic cadastral information collection. Among them, the positioning accuracy of the single GPS system is better than 10 meters, and the differential global positioning system (Difference Global Positioning System, referred to as DGPS) technology is used to obtain the DGPS differential data by using the differential GPS reference station with known accurate three-dimensional coordinates, and then the The differential data is sent to the user's receiver in real time or afterwards, and error correction is performed on the user's measurement data, and the positioning accuracy can reach centimeter and millimeter levels. [0003] Precision A...
