AUTOMATIC LOCOMOTIVE SIGNALING RECEIVER WITH USEFUL SIGNAL RECOVERY FUNCTION Russian patent published in 2023 - IPC B61L25/06 

FIELD: means for receiving and processing ALS signals.

SUBSTANCE: receiving device is connected between the locomotive coils and safety devices, and includes a low-pass filter, three parallel-connected blocks for calculating the cross-correlation function between the ALS signal received from the rail line in the form of a signal-to-noise mixture and the given reference signals of the numerical codes KZh, Zh and Z, the inputs of which are connected to a low-pass filter, and a decision block, the inputs of which are connected to the outputs of the cross-correlation function calculation blocks, and the output is connected to the executive relay of the locomotive safety devices, providing the formation of a useful signal based on the identification of the received code message and its transmission to the executive relay of locomotive safety devices for its amplification and decoding.

EFFECT: increased stability of automatic locomotive signaling of continuous operation under conditions of high-intensity electromagnetic interference on railway sections electrified by alternating current.
