If the conveying parameter coincidence coefficient of the target textile yarn corresponding to a certain conveying section is smaller than the conveying parameter coincidence coefficient threshold value and the conveying process evaluation coefficient of the target textile yarn is smaller than the conveying process evaluation coefficient threshold value, marking the early warning reason of the target textile yarn corresponding to the conveying section as that the conveying parameter and the conveying process are not in accordance.
Further, maintenance personnel regulate and control the early warning reasons corresponding to the early warning conveying sections according to the target textile yarns.
The specific operation of adjusting and controlling the early warning reasons corresponding to the early warning conveying sections according to the target textile yarns is that if the early warning reasons corresponding to a certain conveying section of the target textile yarns are that conveying parameters are not satisfactory, the tension and the speed of the equipment corresponding to the left and right sides of the conveying section of the target textile yarns are adjusted.
If the early warning reason of the target textile yarn corresponding to a certain conveying section is marked as that the conveying process is not satisfactory, stopping immediately, and manually adjusting the position of the target textile yarn corresponding to the conveying section or replacing the textile yarn.
The information storage library is used for storing the surface allowable roughness of the equipment, storing standard basic information evaluation coefficients, standard fineness, standard uniformity and standard elasticity corresponding to the standard basic information evaluation coefficients, storing basic information evaluation coefficient ranges corresponding to each reference conveying parameter, and storing the number of conveying sections and the standard length of the conveying sections of the target textile yarns in the conveying process.
According to the invention, the actual conveying parameters and conveying information parameters of the target textile yarns corresponding to the conveying sections are obtained, so that the conveying evaluation condition of the target textile yarns corresponding to the conveying sections is analyzed, stable quality and performance of the yarns in the conveying process are ensured, factors possibly causing yarn flaws such as excessive tension, speed mismatch, position deviation or excessive yarn fineness change are timely found and adjusted, fluctuation of the quality of the textile yarns is reduced, and the stability and consistency of the quality of products are improved.
The foregoing is merely illustrative and explanatory of the principles of this invention, as various modifications and additions may be made to the specific embodiments described, or similar arrangements may be substituted by those skilled in the art, without departing from the principles of this invention or beyond the scope of this invention as defined in the claims.
