METHOD FOR ACCELERATED MEASUREMENT OF TRAIN BRAKE NETWORK DENSITY AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2019 - IPC B60T17/22 

FIELD: rail vehicles.

SUBSTANCE: invention relates to railway transport, namely to devices for diagnostics of brake network of a train. According to the method for accelerated metering of the train brake circuit density during operation of the locomotive with the train irrespective of the pressure in the main tanks, the device for accelerated metering of the train brake network density performs continuous measurement of the pressure change time for the specified minimum interval, for example, from 8.95 kgf/cm² up to 8.85 kgf/cm², that is given pitch of 0.1 kgf/cm², then by means of discrete processing of curve of pressure reduction in main reservoirs from time under action of leaks of brake network of train by means of mathematical model its density is calculated and information is displayed on display. Device for implementation of the method of ACS consists of a power supply unit, a microcontroller, an interface unit, a measuring device for pressure of the supply main line and a display and is intended for implementation of the method for accelerated measurement of the density of the brake network of a train. Pressure gauge of the supply main line is configured to supply a signal characterizing pressure in the main reservoirs of the locomotive to the microcontroller. Microcontroller is configured to after the said signal to calculate pressure reduction time by the specified minimum pitch of 0.1 kgf/cm² and by means of iteration coefficient of correction, which corrects exponentiality of curve of pressure reduction in main reservoirs of locomotive from leaks, calculate instruction density.

EFFECT: higher safety of train movement, increased speed.
