MULTI-CHANNEL TRACK RECEIVER OF A TRACK CIRCUIT Russian patent published in 2023 - IPC B61L23/16 

FIELD: railway equipment.

SUBSTANCE: relates to railway automation and telemechanics devices, namely, to track circuit equipment. A multi-channel track receiver of a rail circuit contains at least two independent channels for processing code signals from its rail circuit, the signal inputs of which are combined and form the signal input of a multi-channel track receiver of a rail circuit, and the outputs are connected to the corresponding information inputs of the code signal control block, the decision block device, the first input of which is connected to the output of the code signal monitoring block, and the second input is connected to the output of the diagnostic block, the input of which is connected to the signal input of the multi-channel track receiver of the track circuit, the first output of the decision device block is the output of the multi-channel track receiver of the track circuit, and its second and the third outputs are connected to the restart inputs of the corresponding code signal processing channels.

EFFECT: simplifying the device while simultaneously ensuring its required noise immunity.
