Improved determination of excavator swing boom angle based on angular velocity ratio
The invention relates to an improved determination of excavator swing boom angle based on angular velocity ratio. The invention relates to a system for determining the angle of a swing boom of an excavator. The excavator comprises a frame, a swing boom and a pneumatic or hydraulic cylinder. A cylinder has a first end coupled to the frame and a second end coupled to the swing boom, the cylinder configured to rotate the swing boom. The system includes: a first inertial measurement unit (IMU) configured to be mounted on a swing boom and generate first IMU data; a second IMU configured to be mounted on the cylinder and generate second IMU data; and a processing unit. The processing unit is configured to receive the first and second IMU data, determine a first angular velocity of the swing boom about the first axis of rotation based on the first IMU data and a second angular velocity of the cylinder about the second axis of rotation based on the second IMU data when the cylinder is actuated, and determine a swing boom angle based on a ratio of the second angular velocity to the first angular velocity.
本发明涉及基于角速度比率的挖掘机摆动动臂角度的改进确定。本发明涉及一种用于确定挖掘机的摆动动臂角度的系统，挖掘机包括车架、摆动动臂以及气动或液压缸。缸的第一端联接到车架，且第二端联接到摆动动臂，缸被配置为使摆动动臂旋转。系统包括：第一惯性测量单元(IMU)，其被配置为安装在摆动动臂上并生成第一IMU数据；第二IMU，其被配置为安装在缸上并生成第二IMU数据；以及处理单元。处理单元被配置为接收第一和第二IMU数据，当缸被致动时，基于第一IMU数据来确定摆动动臂绕第一旋转轴线的第一角速度，并基于第二IMU数据来确定缸绕第二旋转轴线的第二角速度，并基于第二角速度与第一角速度的比率来确定摆动动臂角度。
