Real-time high and low speed communication control system of carbon fiber multiaxial warp knitting machine

Abstract

The invention relates to the technical field of textile warp knitting, and specifically relates to a real-time high and low speed communication control system of a carbon fiber multiaxial warp knitting machine. The system comprises a real-time high-speed PowerLink bus, low-speed X2X communication buses, and a man-machine operating device connecting the real-time high-speed PowerLink bus and the low-speed X2X communication buses through a signal converter. The low-speed X2X communication buses are connected with a master controller in a communication manner, a first weft thread controller connected with the master controller in a communication manner, a second weft thread controller connected with the first weft thread controller in a communication manner, a third weft thread controller connected with the second weft thread controller in a communication manner, and an assistant controller connected with the third weft thread controller in a communication manner. The system manages in a centralized manner, and controls in a distributed manner, and coordinates and manages each control unit, thereby greatly improving operation stability and efficiency of the system.

Description

technical field [0001] The invention relates to the technical field of textile warp knitting, in particular to a real-time high and low speed communication control system for a carbon fiber multiaxial warp knitting machine. Background technique [0002] The carbon fiber multi-axial warp knitting machine is mainly used to weave carbon fiber multi-axial fabrics of various specifications. Structural design for directional reinforcement. The fabric of this structure has isotropic adaptability and strain capacity, as well as extremely high resistance to tear transmission and good conformability. Therefore, multi-axial carbon fiber warp knitted fabrics have unique advantages in the field of flexible composite materials. Due to the special properties of carbon fibers, they are widely used in composite materials. Good application prospects are the cutting-edge equipment that countries are vying to develop. [0003] The carbon fiber multi-axial warp knitting machine is a very comp...

Problems solved by technology

Such a large complex control system cannot be realized by traditional centralized control system and general distributed control system, and foreign countries have blocked the control technology of carbon fiber multiaxial warp knitting machines, so it is necessary to invent new control methods to adapt to carbon fiber multi-axis Large and complex linkage system of axial warp knitting machine

The traditional design method is centralized control, that is, a computer is used to control each component in a time-sharing manner. Such centralized control is difficult to realize for devices with many components. Although the centralized control method is cheap, the functions are relatively simple and the real-time performance is poor. , low maintainability, poor expandability, suitable for small control devices with few components
