Abstract

The invention provides a calibration method for an X-ray nuclear scale and the X-ray nuclear scale. The calibration method is applied to the X-ray nuclear scale. The X-ray nuclear scale includes an X-ray source, an X-ray detector, brackets and a weighing instrument. The method includes the steps that the weighing instrument acquires X-ray energy and intensity output by the X-ray detector and a tube voltage parameter and a tube current parameter sent by the X-ray source; the weighing instrument determines the offset of the tube voltage parameter and the offset of the tube current parameter according to the tube voltage parameter and the tube current parameter respectively; the X-ray source adjusts the tube voltage parameter and the tube current parameter based on the offset of the tube voltage parameter and the offset of the tube current parameter. According to the calibration method of the embodiment, the X-ray detector is doubled as a feedback sensor for monitoring the X-ray energy and intensity, the tube voltage and tube current of the X-ray source are controlled through feedback to keep the X-ray parameters of the X-ray source constant, and the measurement stability of the X-raynuclear scale is improved.

Description

Technical field [0001] The invention relates to the technical field of weighing, in particular to a calibration method of an X-ray nuclear scale and an X-ray nuclear scale. Background technique [0002] Coal has always occupied a dominant position in the structure of my country's energy industry. In order to improve economic efficiency and strengthen the supervision of coal production links, coal mining enterprises generally install isotope nuclear scales on the belts of the mining face to monitor the raw coal recovery rate in the mining area in real time to ensure the effective recovery of coal resources. [0003] The coal mining technology of coal mining face adopts the "reverse method" for coal mining. The belt conveyor opportunities of the underground mining face are shortened with the advancement of the coal mining face, causing changes in belt tension. The isotope nuclear scale installed on the belt conveyor adopts "non-contact" weighing, and the isotope nuclear scale adopts...
