AI Technical Summary
Existing systems for determining the swing boom angle of excavators rely on integrating gyroscopes, which suffer from drift due to sensor noise and uncorrected bias, and require alternative methods that do not depend on gyroscopes or gravity measurements for accurate angle tracking.
A system using a first measuring sensor to determine discrete interim swing boom angles and a second measuring sensor to correct for drift, combined through sensor fusion algorithms like complementary filters or Kalman filters, with optional self-calibration procedures to maintain accuracy.
Provides accurate and stable measurements of the swing boom angle by correcting for long-term drift and sensor errors, ensuring precise angle determination without frequent operator calibration.
