Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] refer to figure 1 , the measuring system structure of the present invention is, comprises the parallel laser source 6 that is arranged on conveying line directly above and detection sensor, and detection sensor is connected with FPGA processor 3 in addition,

[0015] The parallel laser source 6 adopts a parallel laser with a wavelength of 635nm to 650nm, which can emit parallel laser lines to the strip on the conveying line, with high power, long service life, easy installation and use, and the parallel laser source 6 irradiates vertically downward The parallel laser line should be perpendicular to the plane of the strip, and the parallel laser line illuminated on the strip must be perpendicular to the forward direction of the strip;

[0016] The FPGA processor 3 has a high-speed digital signal processing function, and the FPGA proces...

Abstract

The invention discloses a strip width and center measurement system based on parallel laser rays, and further discloses a strip width and center measurement method based on the parallel laser rays. According to the method, an area array CCD is fixed, a light source of the parallel laser rays is made to be perpendicular to a strip, the area array CCD obtains signals related to the edges of the strip by detecting the parallel laser rays, the signals pass through an external high-speed A / D converter, then digital signals are obtained and then pass through an FPGA processor to be processed, and the signals are transmitted to an upper computer through a USB2.0, and finally a result is displayed. The strip width and center measurement system and method based on the parallel laser rays have the advantages of being high in detection precision, good in stability and simple in structural design.

Description

technical field [0001] The invention belongs to the technical field of photoelectric measurement, and relates to a strip width and center measurement system based on parallel laser lines, and also relates to a strip width and center measurement method based on parallel laser lines. Background technique [0002] With the increasing development of modern industry, the measurement of strip width and central parameters on high-speed production lines is an important problem that needs to be solved in modern industrial production. The degree of automation in the strip production process continues to increase, and the following industrial needs appear: In order to improve The yield of the strip is stable and the product quality is stable. The width of the strip needs to be measured during production. At the same time, in order to overcome the phenomenon of deviation during the winding process of the strip, the position of the center of the strip must be accurately determined. These...
