Embodiment 1

[0016] The entire warp knitted fabric defect detection controller is mainly composed of TMS320 digital signal processor system. In the process of processing warp knitted fabric defect data, the composition block diagram is as follows figure 2 shown. When the warp-knitted fabric defect data is changed, the system microcomputer is used to input the defect data through the RS232 interface and stored in the warp-knitted fabric defect processor.

[0017] Warp knitted fabric defect memory is used to store defect data; keyboard and display are used to input warp knitted fabric structural parameters and other working parameters; RS-232 serial communication interface receives defect data transmitted from host computer; digital signal processor Responsible for the operation control and data processing of the entire defect processor.

Abstract

The invention provides a digital signal processor (DSP) controller special for detecting defects of warp-knitted fabrics, belonging to the field of novel textile machinery. The warp-knitted fabrics have the defects of wide varieties and complex detection algorithm, so the specific detect treatment flow is needed to be selected according to the varieties and relevant characteristics of the defects during defect detection. By adopting a simple single software treatment method, the real-time control requirement of defect detection can not be met obviously. In order to solve the technical problem, in the invention, a DSP is taken as the core of a control system and is used for reading the varieties and relevant characteristics of the defects and controlling the subsequent treatment flow of the defects of the warp-knitted fabrics so as to meet the real-time control requirement of defect detection treatment, thus completing the treatment flows of the defects of the warp-knitted fabrics.

Description

technical field [0001] The present invention relates to the development of a special control system for warp-knitted fabric defect detection with a digital signal processor as the core. The data controls the action of the stepping motor in real time to realize the control of the defect detection and processing mechanism, so as to achieve the effect of real-time processing of defects. Background technique [0002] In the production process of warp knitted fabrics, due to the yarn and weaving process, defects such as slubs, missing warps, missing wefts, holes, and oil stains will be formed on the cloth surface. After the production of warp knitted fabrics is completed, the computer digital image processing technology can be used to locate the fabric defects and extract the characteristic parameters of the fabric defects to classify the defects. After completing the identification and classification of warp-knitted fabric defects, it is necessary to make corresponding marks on...
