Embodiment Construction

[0015] Now in conjunction with accompanying drawing, the present invention will be further described:

[0016] refer to figure 1 -3. The yarn state detection method based on fluff analysis, a U-shaped casing, and an electronic control device arranged inside the casing, the electronic control device includes a power supply circuit for supplying power, and a circuit for calculation and processing A processor, an infrared emitting unit 1 and an image sensor 2 connected to the processor, and an infrared filter 3 is arranged on the image sensor 2 .

[0017] The power supply circuit converts the input power level and stabilizes the voltage to provide power for other circuits.

[0018] The image sensor 2 is configured as a CCD linear image sensor or a CMOS linear image sensor sensitive to infrared rays, and the processor can read image data as required.

[0019] The infrared filter 3 can filter out light other than infrared light, which can greatly improve environmental adaptabilit...

Abstract

The invention discloses a yarn state detection method based on pile edge analysis. A housing and an electronic control device arranged in the housing are adopted. The electronic control device comprises a power supply circuit for supplying power, a processor for performing operation processing, an infrared emission unit and an image sensor, wherein the infrared emission unit and the image sensor are connected with the processor; an infrared filter is arranged on the image sensor; the infrared emission unit is arranged over the image sensor; and a yarn state recognition method is set in the processor. The method comprises the steps that: (1) the processor collects image data ft (x, y) output by the image sensor every fixed period T; (2) binarization processing is performed on the image dataft (x, y) by adopting a binarization algorithm to obtain a binary function yt (x, y); (3) a y value maximum point (xtmax, ytmax) and a y value minimum point (xtmin, ytmin) of the projection area of the binary function yt (x, y) is calculated; (4) the sum S of the distances between the maximum point and the minimum point of the current collection and the last collection is calculated; when S is greater than or equal to a preset threshold value K, it is judged that a yarn is in a motion state, otherwise, it is judged that the yarn is in a static state.

Description

technical field [0001] The invention relates to a yarn state detection method based on fluff analysis, which belongs to the technical field of textile electronics. Background technique [0002] Dressing is a basic requirement of life for everyone, so the textile industry has a long history of development. But in modern times, the automation of textile machines has only developed, and unmanned production has been realized in recent years. For example, the seamless underwear machine can completely weave a piece of clothing without human intervention, so the work efficiency is very high and the production cost is greatly reduced. After the automatic production is realized, the control of the production process is particularly important. For example, seamless underwear will be woven with multiple sets or even more than ten sets of yarns, even if a set of yarns is broken or lacking yarns, the currently spun clothes will be scrapped. The currently used yarn state sensor uses a ...
