发明名称 Slope and motion compensator for weighing on a dynamic platform
摘要 A weighing material on a moving platform by compensating for acceleration of the material and a variable slope of the platform. The system includes at least one weighing load cell and a reference load cell. The weighing load cell generates an output signal associated with a force applied to the weighing load cell by the material. The reference load cell is coupled with a reference mass, and provides the data from which a compensation multiplier can be calculated. The compensation multiplier is a value that is used to adjust the output of the weighing load cells to compensate for acceleration and variable slope, thereby generating the actual weight of the material. In order to calculate the compensation multiplier, an zero offset value of the reference load cell is determined prior to taking weight measurements of the material. The weighing systems can be used with substantially any moving vehicle that carries a material. Examples include vehicles having conveyors for carrying harvested crops or other materials, vehicles having a weigh chamber used to measure fixed volumes of crops, feed wagons, and other uses outside of agriculture.
