Weight calibration method based on precise weighing

Abstract

The invention relates to a weight calibration method based on precise weighing. The method comprises the following steps: acquiring a first image of an object to be weighed on an objective table in real time by using a monitoring device; determining the deviation degree of the actual position and the target position based on the position of the to-be-weighed object on the objective table in the first image, and setting a first correction coefficient according to the actual deviation degree; when the actual signal of the sensor array on the objective table is converted through the conversion unit, correcting the actual signal through the first correction coefficient, and obtaining a first correction value; displaying the first correction value as a to-be-displayed value, wherein the to-be-displayed value is the weight of the to-be-measured object; expressing the degree of the to-be-measured object deviating from the center position of the objective table through the first correction coefficient, and then correcting the influence on the reference signal, so that the corrected signal value can be equivalent to the fact that the object to be weighed is placed in the center of the objective table, errors caused by position deviation are effectively corrected, accurate weight measurement is achieved, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of weighing, in particular to a weight calibration method based on accurate weighing. Background technique [0002] With the rapid development of modern industry, precision measurement has been applied in various industries, and higher requirements have been put forward in terms of measurement accuracy. Traditional measurement is done by Jiyou measuring instruments, and the measurement range of different measuring instruments is limited. Yes, but the accuracy is also limited. For example, when weight is used as the basic unit, the measurement accuracy is nearly 1g, and further accurate measurement cannot be performed for weights less than 1g, so various measuring instruments have limitations. [0003] In order to overcome this limitation, an electronic scale has emerged as the times require. The electronic scale adopts electronic pressure-sensitive technology, that is, the weight data is converted according ...
