DEVICE TO CONTROL FILLING OF HUMP YARD TRACKS Russian patent published in 1998 - IPC

FIELD: railway transport; signalling systems; continuously revealing cuts in each point of rail track by simultaneous interrogation of similar track pickups in different rail tracks. SUBSTANCE: device has track pickups 2.1.1-2. m. n in each track of control sections 1.1.1.-1.m.n. Pickups have inductive stubs with crossing within the limits of control section. Inductive stub is inductor of oscillatory circuit of AC generator 4 whose output is connected to first input of AND gate 5, to second input of which output of pickup address decoder 6 is connected. Outputs of track pickups are connected to information inputs of on-line storage unit 7. Input of decoders 6 are connected with one of outputs of pickup address coder 8 whose inputs are connected with corresponding outputs of control signal shaping unit. EFFECT: enlarged operating capabilities. 3 cl, 3 dwg
