A weighing measurement and control synthesis method and loading device

Abstract

The invention relates to the technical field of mass weighing and error determination / calibration of electronic scales and in particular provides a weighing measurement and control synthesis method and loading device. The loading device is connected to a digital indicator scale and is further connected to a mechanical loader and a matching block or a weighing synthesizer and a matching block so asto calculate the synthesis mass [delta] m; then, according to the formula M1=f+0.5e-[delta] m-f0-fc or M2=f+0.5e-[delta] m-f0, the post-synthesis actual weighing value is calculated and the actual weighing value is shown through digital display of a display. By correcting zero error, the accuracy can be increased by about 30%; when the indicating value error and zero error can be corrected, the accuracy can be increased by more than 60%; the accuracy is basically the same as the accuracy of common scale measurement, so that many conventional scales can realize electromechanical integration measurement automatically with greater accuracy, can complete weighing at a time conveniently, and can obtain more accurate weighing values; the related methods, techniques, processes and standards canbetter meet requirements; the weighing accuracy in trade is improved.

Description

technical field [0001] The invention relates to the technical field of mass weighing and various error verification / calibration of electronic scales, in particular to a weighing measurement control synthesis method and a loading device. Background technique [0002] At present, the mass range of weighing various substances at home and abroad is usually (0-60)t, and most of them use digital indicating scales (hereinafter referred to as scales) for direct weighing. There are three problems and shortcomings in the direct weighing method: 1) the error of the scale used cannot be corrected. 2) The digital display rounding error will be introduced during weighing, and the error it introduces will be larger with the increase of the division value d: the maximum is 1 / 2 division value d. 3) When the weighing is greater than 30kg and requires high accuracy, the existing scales cannot meet the requirements. There are two problems when using electronic scales to weigh: on the one hand...
