Embodiment 1

[0016] The entire yarn appearance parameter detection controller is mainly composed of MELSEC FX2N-80MR system, and the yarn appearance parameter detection processor is mainly composed of MELSECFX2N-80MR, storage body, communication interface and keyboard display, etc. Process the yarn appearance parameter data, the composition block diagram is as follows figure 2 shown. When the yarn appearance parameter data is changed, the system microcomputer is used to input the yarn appearance parameter data through the RS232 interface and store it in the yarn appearance parameter processor.

[0017] The yarn appearance parameter memory is used to store the yarn appearance parameter data; the keyboard and display are used to input the yarn appearance parameter type parameters and other working parameters; the RS-232 serial communication interface receives the yarn appearance parameter data transmitted from the host computer ; PLC is responsible for the operation control and data proces...

Abstract

The invention discloses a special programmable logic controller (PLC) for detecting apparent parameters of a yarn, and belongs to the field of a novel textile machine. As more types of the apparent parameters of the yarn exist, when the apparent parameters of the different yarns are detected, the motion speeds of the yarns, the types of detection heads, and the distances between the detection heads and the yarns are different. Therefore, when the apparent parameters of the yarn are detected, the special detection flow is selected according to the type of the apparent parameters of the yarn to be detected. The real-time control requirement of detecting the apparent parameters of the yarn cannot be met by a simple and unique software processing method. In order to solve the problem, the PLC controller system is taken as the core of a control system. The types and the relevant characteristics of the apparent parameters are read by the PLC controller system, and the processing flow of detecting the apparent parameters of the yarn is subsequently controlled by the PLC controller system; therefore, the real-time control requirement of processing the apparent parameters of the yarn is met, and the processing flow of detecting the apparent parameters of the yarn is finished.

Description

technical field [0001] The present invention relates to the development of a special control system for yarn appearance parameter detection with the PLC system as the core, specifically relates to the use of PLC to read the types of yarn appearance parameters 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 Therefore, the control of the yarn appearance parameter detection and processing mechanism is realized, so as to achieve the effect of real-time processing of the yarn appearance parameter detection. Background technique [0002] After yarn production, it is necessary to evaluate the yarn quality. The commonly used standard for yarn quality evaluation is the appearance parameters of the yarn. Therefore, it is necessary to complete the detection of the yarn appearance parameters, so as to evaluate the yarn quality grade. Similarly, when yarn production is carried out according...
