DEVICE FOR OPERATING TRAMCAR SWITCHES FROM TRAIN Russian patent published in 2002 - IPC

FIELD: city rail transport. SUBSTANCE: device has first and second order transmitters with antennas mounted in head and tail of train, turn signal receiver, turn signal discrimination ut and logic stage connected, respectively, with turn signal receiver and first and second power commutators which are connected, respectively, with electric drives of first and second switches and contact wire. Logic stage has turn signal logic processing unit and first and second amplifier units. Outputs of signal receivers are connected, respectively, to inputs of turn signal discrimination unit whose output is connected to input of turn signal logic processing unit. Outputs of each unit of amplifiers are connected, respectively, to control inputs of corresponding commutator. EFFECT: improved reliability of transmission of information characterizing non-occupied state of switch zone and blocking of tramcar switch when train is passing. 3 cl, 3 dwg
