Metering and positioning system for molten iron tank, and molten iron transport production line

Abstract

The invention belongs to the technical field of metering systems, in particular to a metering and positioning system for a molten iron tank, and a molten iron transport production line. The metering and positioning system of the molten iron tank comprises a railway scale, a positioning module, a visual imaging module and a control module, wherein the positioning module corresponds to the railway scale, the visual imaging module corresponds to the calibration position of the railway scale, the control module controls the visual imaging module to start running according to a return signal of thepositioning module and calculates the offset of a molten iron tank car relative to the calibration position of the railway scale according to the return image information of the visual imaging module, the positioning module monitors the molten iron tank car and sends data information, the visual imaging module acquires a label image on the molten iron tank car, and the control module compares thelabel image with the marked position of the railway scale to calculate the offset of the center position of the label image relative to the marked position. The operator adjusts the positional relationship of the molten iron tank car relative to the railway scale according to the offset, which realizes the precise low-error positioning of the molten iron tank car.

Description

technical field [0001] The invention belongs to the technical field of metering systems, and in particular relates to a metering and positioning system for a molten iron tank and a molten iron transportation production line. Background technique [0002] In iron and steel production, it is often necessary to use the molten iron tank rail car to transport the molten iron. When the molten iron is transported, it is first necessary to drive the molten iron tank rail car onto the track scale to measure the molten iron contained in the molten iron tank. [0003] When the molten iron tank rail car is weighed and measured on the rail scale, it needs to be accurately positioned on the rail scale to ensure accurate measurement results. At present, the positioning of the molten iron tank rail car on the rail scale is usually done manually, so due to the high error rate of manual operation, this will cause a high error rate in the weighing and measurement of molten iron.
