Abstract

Methods and apparatus are provided for determining the attitude and heading angle of a crane jib. Crane jib angular velocity, crane jib roll angle, crane jib pitch angle, crane jib specific force, and magnetic field in the local operating environment of the crane jib are all sensed and supplied to a processor. All of these measurements are processed, in a processor, to estimate the attitude and heading angle of the crane jib.

Description

technical field [0001] The present invention relates generally to an attitude and orientation reference system, and more particularly to an attitude and orientation reference system for a crane arm. Background technique [0002] Tower cranes are used in a variety of environments. Two of the more common environments are construction sites and shipyards because of the combination of height and lifting capacity offered by this type of crane. A tower crane typically includes a base, a mast and a jib. The base is fixed to the ground and is also connected to the uprights. The slewing unit is connected to the mast and is used to rotate the crane. Furthermore, the crane jib includes a load bearing section, a counterjib section and an operator cab. [0003] The load-bearing portion of the crane jib typically carries the load. The balance arm section is connected to the load section and carries a counterweight to balance the crane arm while the load section carries the load. The...
