SWITCH SECTION CODING DEVICE Russian patent published in 2006 - IPC B61L23/16 

FIELD: railway transport; signaling and communication.

SUBSTANCE: invention relates to version of coding of ramified track circuit with use of rail conducting communication lines providing continuous transmission of cab signaling coded signals strictly to set route at running of locomotive both at plus and minus positions of switch. Device contains coded signals transmitting unit, track transmitting relay, track code transformer and switch plus and minus position pickup. Device remains serviceable at any type of train haul, and it can be used in standard continuously-controlled cab signaling at automation of shunting motions in systems to prevent collision of moving units. There are no dead zones where coded signals are not received by cab signaling receivers, thanks to which number of failures of devices is reduced. Current in rails of switch section under receiving coils, when locomotive runs along preset route, remains stable in value over entire route.

EFFECT: improved reliability of cab signaling system, reduced consumption of power.
