Abstract

FIELD: transport.
SUBSTANCE: in the method, voice-frequency signal is fed into rail line at its one end, and at the other end, signal modification is checked having previously determined thresholds of occupation and clearance, the thresholds are determined at the moment of voltage spike which appears provided that input resistance of receiver end is of complex character with capacitive component. In this process, control of states is performed for ramified rail line without boundary isolating joints to which line the signal is fed from its middle reducing zones of preliminary and additional bypassing, rail line occupation control is fixed after clearance of approach section or with occupation of the second after the signal track section by switching train signals which are shifted against train movement direction for a distance corresponding to preliminary bypassing zone.
EFFECT: higher reliability of ramified rail line operation.

Description

The invention relates to the field of railway automation and can be used to regulate the movement of trains at the station.

A known method of monitoring the status of the arrow-track sections, which consists in the fact that the current voltage at the input of the receiver is compared with the threshold voltage of occupation and release. When the current voltage drops below the threshold voltage value, occupation is fixed as occupation of the rail circuit, exceeding the current voltage of the threshold value of the release voltage - release of the rail circuit [Arkatov B.C. Rail chains of the main railways. - M: “Mission M LLC”, 2006 (p. 434, Fig. 8.4)].

The disadvantage of this method is that in the schemes of rail lines provide unreliable insulating joints.

There is a method of controlling the freedom of a rail line, which consists in the fact that a tone signal is applied to an unbranched rail line at one end, and a signal change is monitored at the other end, having previously determined threshold occupation and release thresholds, threshold values are determined at the time of a voltage surge that occurs provided that the input impedance of the receiving end is complex with a capacitive component [RF Patent No. 2333126. The method of controlling the freedom of the rail line, the authors of the Field Yu.I., Troshina M.V., Akhmadullina F.R., Yakobchuk A.I., publ. September 10, 2008, BI No. 25].

The disadvantage of this method is that it cannot be used for branched rail chains due to the sufficiently long pre-shunt zone, as well as low operational reliability.

This technical solution is selected as a prototype.

The technical result is to increase the reliability by reducing the number of insulating joints and expanding functionality by monitoring a branched rail line.

The technical result is achieved by the fact that in the method of monitoring the state of the arrow-track sections, which consists in the fact that the tone line signal is supplied to the rail line at one end, and the signal change is monitored at the other end, having previously determined the occupation and release thresholds, the threshold values are determined at the time of a surge, which occurs provided that the input impedance of the receiving end is complex with a capacitive component, according to the invention, They install a branched rail line without boundary insulating joints, the signal to which is fed from its middle, reducing the areas of preliminary and additional shunting, the control of the occupancy of the rail line is fixed after releasing the approach section or by taking the second track signal by switching train signals that are shifted against the direction of travel trains to a distance that corresponds to the pre-shunt zone.

By reducing the shunt zone, a branched rail line is controlled without boundary insulating joints, which increases the reliability of the rail line and EC devices and expands its functionality.

The drawing shows a diagram e of the track development without boundary insulating joints (joints on the translated curves are provided).

The action of branched rail chains with insulating joints corresponds to the operation of typical rail chains [see Arcatov B.C. and etc.]. When the switch-track sections are in a free state, the track receivers of the rail chains are excited.

The method is implemented in the scheme, which shows the track sections 1-5 and switch-track sections 6 and 7, power generators 8 and 9, track receivers 10-19, signals 20-26, track receivers 27, 28.

The method is as follows.

The supply generators 8 and 9, which supply an alternating current signal (tone frequency) to the rail line, are included in the middle of the rail chains of the arrow-track sections 6 and 7. The track receivers 10-19 and 27-28 are located at the ends of the rail chains of the track sections 1-5 and arrow-track sections 6 and 7, which reduces the distance from the generators to the receivers, which reduces the length of the zone of preliminary and additional shunting. Integrated input impedances of track receivers with a capacitive component also contribute to the reduction of the shunt zone. The reduction of the bypass zone makes it possible to control the freedom of branched rail chains without boundary insulating joints. For reliable (reliable) fixation of the state of the track sections, as well as the normal transfer of arrows when the rolling stock approaches the signal, signals 20-26 are assigned against the course of the rolling stock to a distance corresponding to the preliminary shunting zone. In the case when the signal cannot be moved to the required distance, the signal overlaps with the control of the release of the approach section, or with the occupation of the second route section along the route. The shunting signal is blocked in the usual manner.

The proposed method allows to control branched rail chains, it improves the reliability of electrical centralization devices by reducing the number of insulating joints and significantly reduce the cost of construction and operation.
