FIELD: metering equipment.
SUBSTANCE: invention is related to the field of instrument making. Device for contactless collection of information on internal defects of rail at any depth of their location inside rail comprises SHF generator, detector, indicator, antenna, serially connected low pass filter, signal amplifier, analog-digital converter, storage device and neural computer. SHF generator is represented by autodyne transceiver, which is connected to antenna and detector input, and output of neural computer is connected to indicator. In process of rolling stock motion vibrating surface of rail is radiated with electromagnetic waves of SHF range, reflecting from which, SHF electromagnetic waves are received by transceiving antenna. Phase detection is used to extract signal that contains information on parametres of rail vibration, which is compared to reference signals stored in device memory. In order to make decision on defects in rail, comparison circuit is used on the basis of neural computer algorithm.
EFFECT: improved efficiency of monitoring.
