Embodiment Construction

[0014] Now in conjunction with accompanying drawing, the present invention will be further described:

[0015] refer to figure 1 -2. Based on the longitudinal width distribution of the yarn monitoring method of the spinning machine, a U-shaped casing is provided, and an electronic control device is arranged inside the casing, and the electronic control device includes a power supply circuit for supplying power, and performs calculation 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.

[0016] The power supply circuit converts the input power level and stabilizes the voltage to provide power for other circuits.

[0017] 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.

[0018] The infrared filter 3 can filter out light other than infrared light,...

Abstract

The invention discloses a method for monitoring yarns of a thread spinner based on longitudinal width distribution. A shell is arranged and an electronic control device is arranged in the shell; the electronic control device comprises a power circuit for providing a power supply, a processor for performing operation processing, an infrared emission unit and an image sensor; the infrared emission unit and the image sensor are connected with the processor, an infrared filter is arranged on the image sensor, and the infrared emission unit is arranged right above the image sensor. The method for monitoring the yarns of the thread spinner set in the processor comprises the following steps that (1) every a fixed period T, the processor collects image data f<t> (x, y) output by the image sensor;(2) a binarization algorithm is used for performing binarization processing on the image data f<t> (x, y) to obtain a binary function y <t> (x, y); (3) the width of a projection area of the binary function y <t> (x, y) is counted along the direction of the y axis to obtain an array W<t> [N]; and (4) the difference value S between the currently collected array W<t> [N] and W<T-1>[N] collected fromthe previous time is calculated: when S is larger than or equal to a preset threshold value K, the yarns are determined in a motion state; otherwise, the yarns are determined in a static state.

Description

technical field [0001] The invention relates to a monitoring method for spinning machine yarns based on longitudinal width distribution, and belongs to the technical field of textile electronics. Background technique [0002] The seamless underwear machine is a special molding production equipment for producing seamless knitwear, which can be used to make underwear, swimwear, sportswear and other categories. According to statistics, in 2010, seamless knitting and traditional knitting accounted for 40% and 60% of the global knitted underwear market respectively. At present, the seamless underwear machine can completely weave a piece of clothing without human intervention, with high work efficiency and greatly reduced production costs. Seamless underwear is 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. Therefore, it is particularly important to monitor yarn breakag...
