METHOD OF AND DEVICE FOR REGISTERING PASSAGE OF RAIL VEHICLE WHEELS THROUGH CHECK SECTION OF RAIL Russian patent published in 2002 - IPC

FIELD: railway transport; railway vehicle registration, location and identification means. SUBSTANCE: according to proposed method low level continuous input signal is formed on check section of rail at absence of wheels on rail section. Corresponding input signal is transformed into intermediate signal from which inertia continuous signal is formed. Output discrete signal is formed when instantaneous value of intermediate continuous signal exceeds instantaneous value of inertia continuous signal. Device for implementing the method has control bridge made of inductive two- terminal networks used as sources of main ac flow. Matching and inertia units and source of additional alternating magnetic flux are provided. EFFECT: elimination of accidental influences by decreasing number of primary transformations. 7 cl, 2 dwg
