Embodiment Construction

[0033] A system for online measurement of fiber winding pitch in composite pipe, including fiber winding machine, CCD camera and processing unit in composite pipe production equipment; fiber winding machine includes 80 silk spindles, 80 silk spindles include 1 or 2 The fiber color of the marked silk ingot is different from the fiber color of the other silk ingots. When there are two marked silk ingots, the colors are also different from each other; generally speaking, the fiber color of the marked silk ingot is colored , the fiber color of the rest of the spindles is white. The marked silk ingots should not exceed one-fifth of the number of all silk ingots at most; when the marked silk ingots are of one color, they should be placed in a centralized manner; when the marked silk ingots are of two colors, they should be placed symmetrically. One or two CCD cameras are aimed at the exit end of the fiber winding machine for real-time shooting of the wound fiber tape; the processing...

Abstract

The invention relates to a system and method for online measurement of fiber winding pitch in composite pipes. The system includes a fiber winding machine, a CCD camera and a processing unit in composite pipe production equipment; the fiber winding machine includes a plurality of silk spindles, and the multiple silk spindles include At least one marked silk ingot, the fiber color of the marked silk ingot is different from the fiber color of the rest of the silk ingots; when measuring, the CCD camera is aimed at the exit end of the fiber winding machine for real-time shooting of the wound fiber tape; the processing unit is used to process the CCD camera real-time images and adjust the pitch in real time according to the processing results. Due to the non-contact optical measurement method, the present invention can detect and feed back and control the rotating speed of the fiber winding machine or the advancing speed of the tractor in real time.

Description

technical field [0001] The invention belongs to the technical field of measuring instrument manufacture and measurement, and specifically refers to a CCD-based method for measuring the distance between colored fibers. Background technique [0002] In the petroleum industry, the technology of winding non-metallic fibers in composite pipes is very common, but in order to ensure the performance requirements of composite pipes, there is a high requirement for the fiber winding pitch. In the prior art, the pitch is detected at intervals of one cycle, and the rotation speed of the filament winding machine or the forward speed of the tractor is adjusted according to the detection result. But there has been no way to monitor the filament winding pitch in real time. Contents of the invention [0003] The purpose of the present invention is to solve the defects of the above-mentioned technologies, and provide a system and method for online measurement of the fiber winding pitch in ...
