Unbalance loading error correction method and system

Abstract

The invention discloses an unbalance loading error correction method and system. The correction method comprises the following steps of obtaining weighing data when a weight is loaded at different positions of a weighing platform of weighing equipment, calculating each piece of weighing data and the average value of the weighing data or the difference value of the weights, when the maximum value in the absolute values of the difference values exceeds a preset threshold value, calculating and updating a sensor correction coefficient, and updating the weighing data, and repeating the steps until the absolute values of all the difference values are smaller than the threshold value. The correction system comprises processing equipment and communication equipment, and the processing equipment and the communication equipment execute the correction method. According to the unbalance loading error correction method, the weighing unbalance loading error is directly processed, so that the correction coefficient of the sensor in the weighing equipment is obtained through calculation and is substituted into the weighing data subjected to unbalance loading correction, the minimum weighing error of the weighing data is ensured, and more accurate unbalance loading error correction is realized.

Description

technical field [0001] The invention relates to a method and system for correcting the eccentric load error of weighing equipment. Background technique [0002] When objects are loaded at different positions on the weighing platform of the weighing equipment, the force on the load cell is different, so an eccentric load error occurs in the weighing equipment. Especially in multi-sensor weighing equipment, such as vehicle scales, platform scales, etc., because the parameters of each sensor are inconsistent, the outputs of the sensors are also inconsistent under the same force, which leads to unbalanced load errors. [0003] In order to correct the eccentric load error of the weighing equipment, the eccentric load correction of the weighing equipment is realized by adjusting the correction coefficient of the sensor. In multi-sensor weighing equipment, it is even more necessary to adjust the correction coefficients associated with each sensor to achieve offset load correction ...
