RAIL TRACK CONDITION MONITORING METHOD Russian patent published in 2020 - IPC B61L23/16 

FIELD: railway vehicles.

SUBSTANCE: invention relates to the field of railway automatics for monitoring conditions of rail lines. In method, signal to rail line is supplied from the middle, rails of transfer curves are shunted by capacitor, which together with rails forms parallel oscillatory circuit - filter-plug at increased frequency of signal current 2000–4000 Hz, oscillatory circuit is equipped with a capacitor, in parallel to which are connected in series connected sections of rail - conversion curves, wherein feed of track line is carried out from points of connection to rails of capacitor, to ends of branches resistors are connected to control integrity of rails of branches, wherein in violation of integrity of rails of one of the branches or imposing a train shunt, resonance conditions of the oscillatory circuit are violated, which shunts the rail line and disconnects the track relay, wherein application of train shunt to section of track in front of rail switches points also leads to deactivation of track relay.

EFFECT: higher reliability of monitoring conditions of track lines.
