WEIGHING SYSTEMS AND METHODS FOR DYNAMIC LOADS

Abstract:

Weighing systems and methods for dynamic loads are provided. A plurality of sensors are configured to provide force information based on a weight of a bin and a weight of a material in the bin. An IMU is coupled to the bin and configured to provide gyroscope information and accelerometer information based on orientation and movement of the bin respectively. A controller is communicatively coupled to the plurality of sensors and to the IMU. The controller is configured to receive the force information from the plurality of sensors and the gyroscope information and the accelerometer information from the IMU. The controller is configured to compensate the force information based on slope of the bin to provide slope-compensated force information, filter the slope-compensated force information using a Kalman filter to provide filtered force information, and estimate the weight of the material in the bin based on the filtered force information.
