INDEPENDENCE OF PARAMETERS OF TECHNICAL CONDITION OF GRAIN HARVESTER CONTROLLED MODES BY DIAGNOSTICS BY VIDEOENDOSCOPY
Abstract
In the article, the author presents the results of the substantiation of the main methodological approach to determining the independence of parameters of the technical condition of grain harvesters of controlled modes by video endoscopy diagnosis. In the article, the author considers the possibility of using the methods of pattern recognition theory to determine various defects of the independence of parameters of the technical condition of grain harvesters of controlled modes by diagnosing them with video endoscopy. Electromagnetic oscillations of the optical range reflected from the surface are used as a characteristic space, the three-dimensional graphs of which are depicted in the axis of the appliqué. The value of reflected signal intensities, which are formed during optical-electronic diagnostics, for example, when using digital video cameras with optical magnification (enough up to 100 times), equipped with backlight, is used as a feature space for defect recognition. The light reflected from the controlled surface is captured by the matrix of a digital camera. Visual analysis of the presented graphic interpretations of the obtained results on a straight line did not allow to find any deterministic or structural features distinguishing these signals. Moreover, purely visually, they look like the implementation of some random processes. Since the most complete characteristic of a random process is its distribution function, histograms were constructed, which are one-dimensional distribution laws of probability of amplitudes reflected from the controlled surfaces of signals, which, unlike the signals of the implementations themselves, already have some structural differences. The authors proposed a dictionary of signs that allows you to clearly distinguish surfaces with roughness and oxidation from clean and oiled surfaces. The authors substantiated that oiled and clean surfaces form intersecting areas, in particular, clean and oiled surfaces have a specular reflection, while oxidized and rough surfaces have a diffuse reflection. This circumstance made it possible to justify the demand for their division, the search for additional signs of recognition, or the development of a decisive rule, which made it possible to divide these classes according to a given criterion.
