Embodiment 1

[0016] The entire yarn appearance parameter detection controller is mainly composed of FPGAMUL501 system, and the yarn appearance parameter detection processor is mainly composed of FPGAMUL501 system, memory, communication interface and keyboard display, 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 ; FPGA is responsible for the op...

example 2

[0021] The entire yarn appearance parameter detection controller is mainly composed of FPGA Altera system, and the yarn appearance parameter detection processor is mainly composed of FPGA Altera system, storage body, communication interface and keyboard display, etc., which are used to receive, store and process yarn during work. Line appearance parameter data, the composition block diagram is shown in Figure 5. When the yarn appearance parameter data is changed, the processed yarn appearance parameter data is stored in the U disk, and the yarn appearance parameter data of the U disk is read into the memory of the yarn appearance parameter detection processor through the USB interface.

Abstract

The invention discloses a special field programmable gate array (FPGA) controller for detecting the appearance parameters of yarns, which belongs to the technical field of new textile machines, and aims to solve the technical problem that because the types of the appearance parameters of yarns are various, and in the process of detecting the appearance parameters of different yarns, the movement velocities of the yarns, the types of detecting heads and the distances between the detecting heads and the yarns are all different, a simple and unique software processing method obviously can not satisfy the real-time control requirements for the detection on the appearance parameters of the yarns through a specific detection process selected according to the type of the appearance parameters of the yarns required to be detected in the process of detecting the appearance parameters of yarns. For solving the technical problem, in the invention, an FPGA controller system is used as the core of a control system for reading in the types and relevant characteristics of the appearance parameters of the yarns, and controlling the subsequent processing flow of the detection on the appearance parameters of yarns so as to satisfy the real-time control requirements for the detection on the appearance parameters of the yarns, thereby completing the processing flow of the detection on the appearance parameters of yarns.

Description

technical field [0001] The invention relates to the development of a special control system for yarn appearance parameter detection with the FPGA system as the core, and specifically relates to using the FPGA embedded system to read the yarn appearance parameter types and related characteristic data and store the information in the memory, and use the data to control the step in real time. The motor moves so as to realize the control of the yarn appearance parameter detection and processing mechanism, 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 to ...
