Embodiment 1

[0016] The entire woven fabric defect detection controller is mainly composed of MELSEC FX2N-80MR system, and the woven fabric defect detection processor is mainly composed of MELSECFX2N-80MR, memory, communication interface and keyboard display, etc., which are used for receiving, storing and processing machine during work. Fabric defect data, the composition block diagram is as follows figure 2 shown. When the defect data of the woven fabric is changed, the system microcomputer is used to input the defect data through the RS232 interface and store it in the defect processor of the woven fabric.

[0017] The woven fabric defect memory is used to store defect data; the keyboard and display are used to input woven fabric structure parameters and other working parameters; the RS-232 serial communication interface receives the defect data transmitted from the host computer; the MELSEC FX2N-80MR system is responsible for the entire defect Processor operation control and data pro...

Abstract

The invention provides a programmable logic controller (PLC) special for detecting defects of woven fabrics, belonging to the field of novel textile machinery. The woven fabrics have the defects of wide varieties and complex detection algorithm, so the specific defect 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. In order to solve the technical problem, in the invention, the PLC is taken as the core of a control system, and a PLC system is used for reading the varieties and relevant characteristics of the defects and controlling the subsequent treatment flows of the defects of the woven fabrics so as to meet the real-time control requirement of defect detection treatment, thus completing the treatment flows of the defects of the woven fabrics.

Description

technical field [0001] The invention relates to the development of a special control system for woven fabric defect detection with the PLC system as the core, specifically relates to the use of the PLC system to read the type of woven fabric defect and related characteristic data and store the information in the memory, and use the data to control the action of the stepping motor in real time. Realize the control of the defect detection and processing mechanism to achieve the effect of real-time processing of defects. Background technique [0002] During the production process of woven 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 woven fabric is produced, the computer digital image processing technology can be used to locate the fabric defect and extract the characteristic parameters of the fabric defect to classify the defect. After completing the iden...
