Excavator intelligent high-precision positioning method based on satellite navigation

Abstract

The invention relates to an excavator intelligent high-precision positioning method based on satellite navigation, belongs to the field of satellite technology comprehensive application, and aims to solve the problem that in the prior art, automatic, intelligent and high-precision positioning of an excavator cannot be achieved. A receiver, a measurement type antenna, a single-axis angle sensor, adouble-axis angle sensor, a vehicle-mounted computer and other devices are installed on the excavator. The accurate positions of the excavator and main parts of the excavator can be solved through a Beidou high-precision space information technology and an analysis algorithm, the relative coordinates of all points under the operation posture of the excavator are reasonably analyzed and solved by constructing side-looking and top-looking two-dimensional coordinates, and accurate positioning of all the main parts can be completed through coordinate system conversion. On the basis of accurate positioning, rapid positioning can be achieved, the positioning precision is improved, automatic guiding and tracking of the excavator are completed, and the engineering application requirements of different industries are met.

Description

technical field [0001] The invention belongs to the field of comprehensive application of satellite technology, in particular to an intelligent high-precision positioning method for excavators based on satellite navigation. Background technique [0002] High-precision positioning, navigation and timing services based on the Global Navigation Satellite System (GNSS) have been widely used in various industries of the national economy such as agriculture, transportation, energy, and electric power. Among them, the coordinate system is the basis of the positioning description: [0003] Space Cartesian coordinate system: the origin of the coordinates is located at the center of the reference ellipsoid, the Z axis points to the north pole of the reference ellipsoid, the X axis points to the intersection point between the starting meridian plane and the equator, and the Y axis is located on the equator plane, tangent to the X axis with a right-handed system at an angle of 90 degree...
