FIELD: traffic control systems.
SUBSTANCE: invention relates to the field of railway automatics and telemechanics for monitoring the states of the distillation rail chains. Method consists in connecting to one of the ends of the rail circuit by means of a two-wire communication line an oscillator of the signal frequency set at the departure station, to the other end – the receiver installed at the receiving station. Moreover, the communication line is interrupted between the points of connection of the receiver and the generator, the second two-wire line is powered by linear devices, and the power is supplied at short intervals, due to which the operation of the counting devices of each linear installation is synchronized with the operation of the station devices, a generator and a receiver are connected to each rail line at predetermined intervals.
EFFECT: is achieved by increasing the handling capacity.
