UA102472C2 - Device for control of passage of cut - Google Patents

Abstract

The invention relates to a railway automation systems. A device for control of passage of cut comprises three inductive loops arranged in a track prism. The first inductive loop is laid on the way to a switch and corresponds to the normal position of the switch. The second inductive loop is laid after the switch. The third inductive loop corresponds to the translated position of the switch. The length of the first inductive loop is larger than the maximum distance between wheels of neighboring cars and not more than the minimum base of car. The distance between the first and second inductive loops and between the first and third inductive loops is less than the minimum base of car. The device also comprises a generator of DC rectangular pulses, a power amplifier, four diodes, three keys, an inverter, an integrator, three amplifiers, three detectors, four comparators, OR gate, two AND gates and a detection circuit of track number. Technical result: increase of accuracy and noise immunity when recording the passage of cut or bases of long-wheelbase cars, as well as prevention of the switch actuation under the rolling stock and control of freeness and occupancy of track sections of a hump yard.
