Detection system and method for single-spindle breakage of spinning frame based on image analysis technology

Abstract

The invention provides a spinning frame single spindle line breaking detection method based on an image analysis technology. The method comprises the steps of A, system initialization, wherein various working parameters are set and transmitted to a server, an image pickup device works, and one photograph is selected as the benchmark photograph; B, power-on work, wherein a traveling device conducts reciprocating motion, the image pickup device takes photographs at regular time intervals, and a transfer system transmits the digitized photographs taken by the image pickup device to the server; C, image processing, wherein an image receiving program in the server receives and records the photographs taken by the image pickup device, and transmits the photographs to an image processing program to conduct processing; D, line breaking judgment, wherein the current photograph is compared with the benchmark photograph, when differences between the two reach preset conditions, it is judged that line breaking failure exists, and the line breaking spindle position information is acquired by calculation; E, failure notification, wherein notification is conducted when the line breaking information is detected; meanwhile F, statistical analysis is conducted.

Description

technical field [0001] The invention relates to spinning technology, in particular to a method for detecting thread breakage of a single spindle of a spinning machine. Background technique [0002] The spinning process is a key process that affects the output and quality of the spinning mill. The spinning frame is an important equipment for completing roving to spun yarn, and the running status of each spindle position directly determines the quality of the spinning yarn, and the broken yarn cannot be detected in time. And processing will cause roller winding and waste of raw materials, reducing the production efficiency of the equipment. The traditional method is to rely on the locomotive worker to go around and find the problematic spindle position. The locomotive operator has a heavy workload, high dependence on personnel, and low efficiency. [0003] In recent years, with the development of information technology in the textile industry, a single-spindle thread breakage...

Problems solved by technology

Due to the characteristics of spinning frame equipment, the number of spindles is very large, so the cost of equipment required to form a system by this method is high. According to the current market price, the price of each spindle is between 40 yuan and 100 yuan, and a small spinning factory has 150,000 spindles. It needs 6 million to 15 million yuan, the implementation cost is too high, and the cost recovery cycle is too long, it is difficult to promote in large quantities
