Description

The invention relates to railway automation, which is capable of controlling the closing and opening of barriers at a distance when a train approaches its moving by road.

Known code automation that controls the closing and opening of the barrier (see the book entitled "Systems for interval regulation of train traffic", author AA Kozakov, EA Kozakov ─ M .: Transport, 1986).

The disadvantage of this automation is that the rails may not have conductivity due to certain reasons, and the codes may not reach the executive system, as a result of which the barrier will not block the move or the arrow will not move to the desired position. Codes can also be distorted, and the overpass will not be blocked by a barrier.

The invention of the USSR is known No. 1193053 and No. 1482845, which block the railway crossing with a barrier using a guard at a checkpoint. But, as you know, the human factor is also far from always reliable.

A decoder that removes codes from a rail is also complex and not reliable. In addition, the code system is expensive and requires special care for it, which is not always provided possible, especially in winter.

The objective of the proposed invention is to increase the reliability of the remote control system of a barrier at level crossings and simplify it.

This problem is solved by the fact that a device is installed in the locomotive driver’s cab that works on the principle of a metal detector, when an increase in the passage of the magnetic field in a certain magnetic circuit causes an increase in the electric signal. And the inductive frame is located outside the driver’s cab while it is connected to an electric signal amplifier located in the driver’s cab, the output of which is connected to the switch of the pulse transmitter capable of reaching the radio receiver installed in the cabinet near the railway crossing post and activates the automation of the barrier control. Opposite the induction frame, at a given distance, on a support, there is a metal plate made of magnetically conductive material and at a given distance from the level crossing.

During the passage of the induction frame, when the locomotive moves past the metal plate, in a known manner, the radio transmitter activates the automation of closing the barrier. And after the locomotive passes through the railway crossing, the induction frame passes by the second metal plate, which is also installed at a predetermined distance from the level crossing and in the same way drives the opening of the barrier in the same way.

The system of remote automated control of a barrier at level crossings is explained by drawings.

In FIG. 1 shows a locomotive with a remote induction frame of a metal detector type device and a metal plate is mounted on a support at a predetermined distance from the railway crossing, and a metal plate is mounted on the support beyond the crossing.

In FIG. 2 shows a sectional view of a locomotive driver’s cab.

In FIG. 3 shows a barrier and a cabinet with barrier control devices.

The remote control system for the barrier contains: locomotive 1, device 2, which operates according to the principle of the metal detector, which is installed in the driver’s cab 3 of the locomotive, the input of which is connected to the induction frame 4, and the output ─ to the switch 5 of the pulse transmitter 6, the metal plate 7 from the magnetically conductive metal, fixed to the support 8, which is grounded, the beam of the barrier 9, spring-loaded with a spring 10, a cabinet 11 mounted near the barrier in which the radio pulse device 12 is installed, connected a solenoid relay 14, which contains armature 15 mechanically connected pivotably via an ear 16 with the bar of the barrier 17 mounted rotatably on the shaft 18.

The system of automated remote control of a barrier at level crossings works as follows.

When the locomotive 1 of the train approaches the railway crossing, the induction frame 4 is mounted opposite the metal plate 7 and the device 2 is triggered in a known manner, which switches on the pulse transmitter 6 by the switch 5, which are transmitted to the radio receiver 12 and thereby actuate the solenoid 14, which retracts the anchor 15, connected with the mechanical beam 9 of the barrier, and the latter, sinking down, closes the overpass in front of the railway track.

After the locomotive has passed the crossing, the induction frame 4 is again mounted opposite the metal plate 7 and the device 2 is triggered in the same way, which transmits a signal to the switch 5, which drives the radio receiver 6 and 12, but the device 13 is already working to de-energize the solenoid circuit and using the spring 10, the beam 9 of the barrier 17 rises, which permits the passage of vehicles through the railway bed.
