Abstract

An excavator 3D integrated laser and radio positioning guidance system (Ex_3D_ILRPGS) comprising: a mobile radio positioning system receiver configured to obtain 2D horizontal coordinates of the excavator, a bucket-to-machine-body positioning system configured to obtain coordinates of the boom, the stick and the bucket of the excavator, a laser detector configured to receive at least one laser beam and configured to provide a local vertical coordinate with a substantially high accuracy, and an on-board navigational system configured to receive and to integrate the 2D horizontal coordinates ofthe excavator obtained by the mobile radio positioning system receiver, the coordinates of the boom, the stick and the bucket of the excavator obtained by the bucket-to-machine-body positioning system, and the local vertical coordinate obtained by the laser detector, and configured to guide the cutting edge of the bucket of the excavator with substantially high vertical accuracy.

Description

technical field [0001] The present invention relates to position tracking and machine control systems, and more particularly, to a combination of laser systems and radiolocation systems configured to complement each other to optimize the tracking and machine control capabilities of prior art systems. Background technique [0002] Recently, there have been many developments in the field of radio ranging or pseudolite mechanical control systems. However, radio ranging or pseudolite mechanical control systems are limited to centimeter accuracy. [0003] For example, a series of mechanical control systems proposed by Trimble include: GCS300 with single elevation control, GCS400 with dual elevation control, GCS500 with slope control, GCS600 with slope and elevation control, and provide centimeter accuracy Full 3D control of the GCS900. In another example, Trimble also proposes the SiteVision HEX machine control system. Version 5.0 of Trimble's Site Vision System includes a 3D ...
