Embodiment Construction
[0050] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0051] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening e...

The invention discloses a method, device and system for detecting and judging faults of spinning parts of a rotor spinning frame on line. The method comprises the following steps of obtaining a yarn signal; calculating unevenness indexes and characteristic yarn fault parameters of yarn according to the yarn signal; averaging the unevenness indexes and the characteristic yarn fault parameters according to the number of spindles of the whole rotor spinning frame; calculating critical values of the unevenness indexes and the characteristic yarn fault parameters according to an averaging result; and judging the running states of the spinning parts of the rotor spinning frame according to the critical values. According to the method for detecting and judging the faults of the spinning parts of the rotor spinning frame on line, the running states of the spinning parts of the rotor spinning frame are judged by obtaining the yarn signal, calculating the unevenness indexes and the characteristic yarn fault parameters of the yarn and performing averaging and critical value calculation sequentially. By the method, the faults of the spinning parts of the rotor spinning frame can be timely and accurately judged, the yarn equipment fault discovery rate is increased, the problem can be found in advance and solved as soon as possible, and the loss caused by equipment faults is reduced.
Description
technical field [0001] The invention relates to the technical field of textiles, in particular to a method, device and system for on-line detection and determination of failures of spinning components of a rotor spinning machine. Background technique [0002] Rotor spinning is a very common spinning method in the spinning industry. In recent years, with the advancement of technology and the rising cost of human resources, rotor spinning has developed rapidly. Spinning components are key components of rotor spinning machines, and their operating status directly affects the quality of spinning. At present, the operating state of the spinning components of the rotor spinning machine can only be tested in the laboratory by sampling the yarn spun by the rotor spinning machine. This method has two deficiencies: one is that when the offline test finds problems with the spinning parts of the rotor spinning machine, it has often caused a large loss and cannot be recovered; The prob...
