Determining a crane tilt angle

摘要

In a method for determining a tilt angle of a crane, a portion of the crane is rotated about a pivot point. A Global Navigation Satellite System (GNSS) receiver antenna is disposed on the portion of said crane. At least three locations of the GNSS receiver antenna are determined by a GNSS receiver in a geo-referenced coordinate system during the rotating. A tilt angle of the crane based on the at least three locations of said GNSS receiver antenna is determined by a processor.

1. A method for determining a tilt angle of a crane, said method comprising:
rotating a portion of said crane about a pivot point, wherein a Global Navigation Satellite System (GNSS) receiver antenna is disposed on said portion of said crane; determining, by a GNSS receiver, at least three locations of said GNSS receiver antenna in a geo-referenced coordinate system during said rotating; calculating, by a processor, a plane of rotation based on said at least three locations of said GNSS receiver antenna; and determining, by said processor, a tilt angle of said crane based on an angular difference between said plane of rotation and a horizontal plane, wherein said tilt angle includes an angular displacement from a first vector normal to said horizontal plane to a second vector normal to said plane of rotation about said pivot point.
