Embodiment 1

[0016] The entire woven fabric defect detection controller is mainly composed of IPC 610P4 system, and the woven fabric defect detection processor is mainly composed of IPC 610P4, memory, communication interface and keyboard display, etc., which are used to receive, store and process woven fabric defect data during work , forming a block diagram such as 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 IPC 610P4 system is responsible for the entire defect processor operation control and data processing.

[0018] The entire woven fabric...

Abstract

The invention discloses an industrial process control (IPC) controller special for detecting woven fabric defects, which belongs to the field of novel spinning machinery. Since various types of the woven fabric defects exist and a detection algorithm is complicated, a specific defect processing flow needs to be selected according to the types of defects and relevant characteristics during defect detection and the requirement of defect detection on real-time control cannot be met by a simple unique software processing method. In order to solve the technical problem, the IPC is taken as the core of a control system and an IPC system reads the types and relevant characteristics of the defects and controls subsequent processing flow of the woven fabric defects, so that the requirement of defect detection on real-time control is met and the processing flow of the woven fabric defects is finished.

Description

technical field [0001] The invention relates to the development of a special control system for woven fabric defect detection with the IPC system as the core, and specifically relates to using the IPC 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 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 identification and ...
