Embodiment 1

[0016] The entire yarn appearance parameter detection controller is mainly composed of CPLD system, and the yarn appearance parameter detection processor is mainly composed of CPLD system, storage body, communication interface and keyboard display, etc., which are used to receive, store and process yarn appearance during work 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 ; CPLD is responsible for the op...

Abstract

The invention discloses a complex programmable logic device (CPLD) controller system special for detecting yarn appearance parameters, and belongs to the field of novel textile machinery. Since a plurality of kinds of yarn appearance parameters are available, the yarn moving speed, the type of a detection head and the distance between the detection head and a yarn are different when different yarn appearance parameters are detected; thus, a specific detection process is selected according to the types of the yarn appearance parameters required to be detected when the yarn appearance parameters are detected, and the real-time control requirement of the yarn appearance parameter detection cannot be obviously met by a simple unique software processing method. In order solve the problem, the CPLD controller system is a core of a control system, the types and related characteristics of the yarn appearance parameters are read by the CPLD controller system, and a processing flow for subsequent yarn appearance parameter detection is controlled by the CPLD controller system, so that the real-time control requirement of the yarn appearance parameter processing is met to finish the processing flow of the yarn appearance parameter detection.

Description

technical field [0001] The invention relates to the development of a special control system for the detection of yarn appearance parameters with the CPLD system as the core, and specifically relates to using the CPLD 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 acco...
