Calibration device and method of double-loader electronic belt scale

Abstract

The invention provides a calibration device and method of a double-loader electronic belt scale. The device comprises a belt, a first loader, a second loader, a speed measuring sensor and a weighing instrument. The first loader comprises a first weighing sensor. The second loader comprises a second weighing sensor. The weighing instrument is electrically connected with the first weighing sensor and the second weighing sensor respectively. A first interface and a second interface of the weighing instrument are respectively used for collecting gravity signals of transmitted materials measured by the first weighing sensor and the second weighing sensor in time intervals such as a preset first time interval, a calibration period and a preset second time interval; a third interface is used for receiving transmission speed signals sent by the speed measuring sensor; and a signal processing unit is used for calculating a second calibration coefficient of the first loader, for calculating a second calibration coefficient so as to finish calibrating the second loader, and for calculating a third calibration coefficient of the first loader so as to finish calibrating the first loader.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electronic belt scales, in particular to a calibration device and method for a double-carrier electronic belt scale. Background technique [0002] In recent years, with the rapid development of the coal mining industry, in order to eliminate the hidden dangers of tax evasion, private mining and excessive mining and damage resources, and accurately grasp the coal output of each coal mine, a remote tax control system for mining output came into being. With the promotion of remote tax control system for mining output, more and more coal mines use electronic belt scales as the main means of output measurement. [0003] Although the electronic belt scale has high measurement accuracy, it has a large amount of daily maintenance, especially the calibration work of the electronic belt scale. In the prior art, the electronic belt scales are calibrated mainly by using hanging code calibration...
