Abstract

The invention discloses an intelligent detection method for weft yarn signals, which realizes intelligent detection of weft yarn signals based on digital signal processing and intelligent pattern recognition technologies. Including analog signal conditioning of weft signal, A / D digital sampling, digital band-pass filter, signal feature extraction, signal pattern learning and memory, formation of signal pattern feature library, signal recognition and other steps, and finally output the weft signal detection result to Loom master control system. In the pattern recognition process, based on the statistical analysis of the weft signal and noise signal, the start and end angle of signal detection, the boundary between the weft signal and the noise signal are automatically learned, no need to manually set the detection parameters, and it is adaptive to the weaving variety , Spray water quality and other changes in the production environment.

Description

technical field [0001] The invention relates to an automatic detection method, in particular to a detection method using digital signal processing and intelligent pattern recognition for weft yarn signals, and belongs to the technical field of textile weaving detection. Background technique [0002] At present, the weft yarn detection on water-jet looms, air-jet looms, and jacquard machines in textile enterprises all use analog signal technology. It is related to the setting of signal sensitivity and peak-to-peak threshold. [0003] For example, the invention patent with the publication number of 101831758B discloses a detection device and detection method for weft yarn breakage of a biaxial warp knitting machine. The detection device includes a programmable computer controller and an input / output module, a programmable computer controller and an input The I / O module is connected in communication, and further includes a diffuse reflection photoelectric sensor, and the diffu...
