TRACK DEVICE OF TONAL FREQUENCY CIRCUITS MONITORING Russian patent published in 2019 - IPC B61L23/16 B61L25/00 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to the field of railway automation, telemechanics and communication for control of track circuits in the system of automatic interlocking and equipment of rail circuits. Track device for monitoring track circuits of tone frequency comprises in-series connected input filter, analogue-to-digital converter, information processing unit includes a controlled filter, a measuring channel, a threshold device, a frequency detector, a decoder, as well as a decision module connected to the CAN interface, a complex signal generator, an operator workstation computer, a digital-to-analogue converter and a power amplifier. At that, the complex signal generator consists of the track line signal summator and signal generators, continuous automatic cab signaling (CACS) signals and integrated continuous automatic cab signaling (ICACS) signals, each of which includes in-series connected signal generator and coder.

EFFECT: broader functional capabilities, high information value and reliability of transmitted information.
