FIELD: transport.

SUBSTANCE: invention relates to railway transport. Proposed method of identification in contactless thermal control by IR hardware proceeds from analysis of bearing heating in every rolling stock unit. Availability of cylindrical or taper bearings is decided on by comparing with preset threshold Qthreshol of indicator Qmean i.e, ratio of mean average excess temperature of bearing assemblies (axle boxes) on even mounted axles to those on odd mounted axles, that is, dTthreshol even-to-dTmean_even ratio. In case indicator Qmean_= dTmean_even /K* dTmean_even >Qthreshold, then, for both taper and cylindrical bearings of rolling stock unit automatically set are higher thresholds of axle box overheating registration, while if Qmean= dTmean_even /K* dTmean_even <Qthreshold, then, for rolling stock cylindrical bearings, set are invariable or decreased said thresholds with due allowance for the fact that numerical values of factor K* are selected from the range of 1.00, 1.05…1.15 and so on depending on quantity of mounted axles in rolling stock units.

SUBSTANCE: method consists in conversion of IR radiation energy of thermal control objects - bearings and journal-boxes - into electric signals with presentation of intermediate results in the form of digital code characterising heating level of objects relative to ambient air temperature in standard units - ADC quanta. To improve reliability of evaluation of bearing and axle equipment condition in the whole it is proposed to calculate ADC quantum value from Plank integral formula in radiation density units according to results of calibration and testing of amplifier channels in autocontrol mode. Herewith, bearing (journal-box) temperature is determined by multiplying its heating in quanta by quantum value in radiation densities with regard to radiation density of running gears having ambient air temperature according to piecewise linear approximation polynom of Plank formula or according to precalculated charts of controlled objects radiation densities and their temperature correlation. These charts are stored in memory of microprocessor controller or automated workstation (AWS) computer of thermal control facilities.

EFFECT: higher reliability of thermal condition evaluation of bearings and axle equipment of moving rail rolling-stock.
