Документ Accuracy of converting videoendoscopy combine harvester using generalized mathematical model(ВЦ НУБіП України, 2018) Grubrin, O.M.; Rogovskii, I.L.The article considers analytical models of the formation procedures for the use of video endoscopy in the assessment of indicators of a technical condition of units and mechanisms of combine harvesters. Developed electronic module for video endoscopy in the 2-s readout of the transducer. As a converter to test the correction unit was used that was developed 13-bit fiber-optic converter of the angle. Experimental studies on the installation and podtverdili that before correction instrumental error exceeding 1/4 of a quantum of high order, equal 0,703125°, and accounted for 1,266° of 1.31°. In the result of the algorithm execution code correction was able to reduce the instrumental error to 0,0089 (1.3% from 1/4 of a quantum of high order), which led to regular operation of the scheme of video endoscopy approval of samples and the formation of true sequence. The results of the processing array of the errors obtained before and after correction
