Problems solved by technology

However, practice has shown that the traditional weft alignment instrument using the PID control method is only suitable for a specific type of fabric, and the type of fabric that can be controlled is single, such as fabrics with similar parameters such as tension and fabric humidity, and cannot adapt to processing multiple fabrics.

Embodiment Construction

[0070] see figure 1 , with reference to image 3 , the present invention's embedded camera whole weft intelligent control method mainly comprises:

[0071] 1) ARM embedded control chip and DSP control chip are used as master and slave controller respectively;

[0072] 2) Use the CCD camera as the signal sensor of latitude inclination, and use the image processing method to calculate and analyze the latitude inclination;

[0073] 3) Adopt the immune fuzzy intelligent control method with learning, memory and self-adaptive ability.

[0074] The working steps of the above-mentioned embedded controller are:

[0075] 1) Adopt a black and white / color CCD sensor with a resolution greater than or equal to 512×512 to ensure a theoretical latitude detection accuracy of 0.15 degrees;

[0076] 2) Each CCD sensor adopts a separate DSP controller for parallel calculation of weft inclination, and has a sufficiently high detection speed when the speed of the whole machine is 0-120 m / min; ...

Abstract

The present invention relates to an embedded image pick-up weft straightening intelligent control method and its control equipment. Said control method is characterized by that: adopting ARM embeddedcontrol chip and DSP control chip and using them as main controller and auxiliary controller respectively; utilizing CCD camera as skewing signal sensor and adopting image processing method to make skewing calculation and analysis; and adopting immune fuzzy intelligent control method with learning, memory and adaptive capability. The controd equipment adopting above-mentioned method includes the following several portions: hardware, software portion, image processing module, input signal pretreatment module, control algorithm module, output interface, communication interface, embedded intelligent controller and CCD camera.

Description

technical field [0001] The invention relates to the technical field of image processing and automatic control, and specifically refers to an embedded camera and weft alignment intelligent control method and a control device thereof. Background technique [0002] During the fabric dyeing and finishing process, due to mechanical and operational reasons, the weft yarn will be skewed and bent. We must rely on weft adjustment equipment to correct the weft skew, weft bend and "S" weft bend that occur during the operation of the fabric. Equal weft displacement phenomenon to improve product quality. Its main mechanism of action is to apply two continuous pulling forces on both ends of the weft of the fabric, and keep the two forces independent of each other, at right angles to the running direction of the fabric, so that various weft skews of the fabric can be corrected. After a certain tension is applied, in order to achieve the shortest distance, the weft will straighten all the ...
