The utility model has the advantages that: the data acquisition system detects the change in thickness of the fiber slivers by use of the rotary encoder, displays the detected data in a wave form on a liquid crystal screen, and statistically calculates the full average thickness, the CV value and the range unevenness of a sample. Compared with the mechanical Saco-Lowell sliver tester, the operational procedures are simplified, the detection results are displayed in a numerical statement form, and the inconvenience of manual calculation is reduced.
Description
Technical field
The utility model relates to the data acquisition system (DAS) that uniformity coefficient detects, and relates in particular to a kind of data acquisition system (DAS) that the fiber strip uniformity coefficient detects that is used for.
Background technology
The fiber strip uniformity coefficient detects in the textile production process, important effect is arranged, the end product quality that is related to later process, the instrument that is used for detection fibers yarn uniformity coefficient at present has two big classes, is respectively mechanical type Saco-lowell evenness instrument and the dried instrument of condenser type bar.Although the detection speed of the dried instrument of condenser type bar is much larger than mechanical dried instrument, its environmental requirement is comparatively harsh, must use under constant-temperature constant-humidity environment, otherwise measurement result has distortion.And the use of mechanical type Saco-lowell evenness instrument is not too responsive to environment, relatively be adapted at interior use of workshop of factory, because what adopt is pure physical construction, manipulate comparatively loaded down with trivial details, to having relatively high expectations of operating personnel, and its measurement result directly is depicted on the coordinate paper with the form of curve, needs manually be estimated according to coordinate scale, can't directly provide performance parameter.
The utility model content
The purpose of this utility model provides a kind of data acquisition system (DAS) that the fiber strip uniformity coefficient detects that is used for.
The technical solution adopted in the utility model is:
A kind of data acquisition system (DAS) that is used for the detection of fiber strip uniformity coefficient, comprise rotary encoder, the outer data-storage system of the grating that tests the speed, keyboard, AVR single-chip computer control system, sheet, liquid crystal indicator, printer and USB communication interface, described rotary encoder links to each other with the AVR single-chip computer control system by data bus with the grating that tests the speed, and described AVR single-chip computer control system also links to each other with the USB communication interface with keyboard, the outer data-storage system of sheet, liquid crystal indicator, printer.
Described rotary encoder is the rotary encoder of relative formula, at least 3600 lines.
The utility model has the advantages that: data acquisition system (DAS) detects the variation in thickness of fiber strip by rotary encoder, can on liquid crystal display, demonstrate waveform, and count complete average thickness, CV value and the extreme difference irregularity etc. of this sample, with respect to mechanical type Saco-lowell evenness instrument, simplified operation steps, testing result directly shows with digitized statistical report form, has reduced the inconvenience that is brought by complicate statistics.
