Abstract

The invention relates to a speed measuring device and a steel plate speed measuring method, and belongs to the field of measurement. The speed measuring device, which is used to measure the speed of amoving steel plate, comprises at least n measurement units, and each measurement unit comprises two adjacent inductors; in the ith group, the two adjacent inductors are in a straight line where a speed vector of the steel plate is positioned, and distance between the two adjacent inductors is di; when the steel plate moves in the preset direction at the speed v0, the two inductors in the ith group (i=1, 2...n) read two random signals, and a time interval between the two random signals in the time domain is ti; and n represents a positive integer greater than or equivalent to 1, and i represents a positive integer greater than or equivalent to 1. Thus, the speed measuring device obtains time interval between test points in the preset distance by the inductors, and obtains the movement speed of the steep plate via a formula. The speed measuring device is simple in structure and convenient to operate, and the speed measuring efficiency and accuracy of the steel plate can be improved obviously.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a speed measuring device and a steel plate speed measuring method. Background technique [0002] Steel plate speed measurement has important practical significance in the engineering field. However, the existing technology is to press the roller on the steel plate. When the steel plate moves, the roller performs pure rolling under the action of friction. The angular velocity ω of the roller is measured with a rotational speed sensor. According to the formula v=ωr (where r is the radius of the roller, v is the speed of the steel plate), the speed of the steel plate can be calculated. [0003] This method has low measurement accuracy and low lifespan. Contents of the invention [0004] The purpose of the present invention includes providing a speed measuring device and a steel plate speed measuring method, which can efficiently and quickly measure the moving speed of a steel plate, a...
