Description

The invention relates to the field of railway automation and telemechanics and can be used in devices for automatically controlling the movement of trains on stages and stations.

A device for automatically controlling the movement of trains on stages and stations. (A.A. Leonov "Maintenance of automatic locomotive signaling", M., Transport, 1982, p. 256).

The disadvantage of this device is the lack of protection against unauthorized pulling of locomotives under the prohibition signal of the input and output traffic lights at the station and the lack of means providing an aimed stop in front of the traffic light with a prohibiting signal indication.

A device for automatic braking control - SAUT (Nikiforov B.D., Golovin V.I., Kutyev Yu.G. "Automation of train brake control". M.: Transport, 1985, p. 263).

This device provides an aimed stop in front of a traffic light with a prohibiting signal indication, but is not protected from unauthorized pulling of locomotives under a prohibiting signal, since its information security on the side tracks of stations is insufficient. In practice, repeated cases of disconnection of safety devices by drivers have been noted, since this system does not allow locomotive work at the station.

A known system of shunting automatic locomotive signaling (Kochnev A.V. "Shunting automatic locomotive signaling", journal "Automation, Communication and Informatics", No. 4, 2000, pp. 43-47) In this system, to increase the information security on the station tracks A radio link is provided between the train driver and the dispatcher. Switching locomotive ALS devices to different modes is performed by the driver, and the system is not sufficiently protected from unauthorized starting and passage of locomotives under the inhibit signal, due to an error of the driver or dispatcher.

A device for preventing collision of rolling stock at the station (RU 2277055, B61L 3/20, 03/12/04). The device is not sufficiently protected from unauthorized starting and driving locomotives under a prohibitory signal, since the driver, acting through a manual control device, can bypass the safety device, without sufficient control from the dispatcher.

The closest in technical essence, selected as a prototype, is the ALSE-Saut microelectronic system, which uses an automatic locomotive alarm in conjunction with an automatic brake control system (Kravtsov Yu.A. “Railway automation and telemechanics systems”, M., Transport, 1996 , p. 143, fig. 5.13.). This system has a strict algorithm for constructing a curve of permissible speed to zero, in front of a traffic light with a prohibiting signal and does not allow the passage of a prohibiting signal when the driver interacts with the system through a vigilance confirmation unit.

The main disadvantage of this system is the limited functionality due to the inability, without turning off the safety devices, to organize movements for the reception and departure of trains from station tracks, with prohibiting indications of traffic lights enclosing them.

The essence of the claimed device is to eliminate dangerous collisions of mobile units, due to the passage of a closed station signal, due to unauthorized and erroneous actions of the driver and the dispatcher.

The technical result, to which this invention is directed, is to expand the functionality, while maintaining high safety of the device.

The technical result is achieved in that in a device for preventing a collision of rolling stock at a station, comprising a train of motion sensors for a train connected to a first input of a software block for controlling the movement of a train, the output of which is connected to an electro-pneumatic valve of the brake system of a rolling stock, a second input for a software control unit the movement of the train is connected to the output of the driver’s alertness confirmation unit, and the third and fourth inputs and the first port are connected, respectively, with the outputs of locomotive receivers of continuous and point inductive communication channels and the transceiver port of the radio channel, locomotive receivers of continuous and point inductive communication channels with their inputs are connected to the corresponding outputs of the stationary transmitters of inductive communication channels, the locomotive transceiver of the radio channel is connected, with its port, to the port of the stationary transceiver , according to the invention, a stationary transceiver of a radio communication channel through a stationary the automatic control unit for the protocol of interaction between the dispatcher and train drivers is connected to a stationary dispatch control unit.

Using the proposed device, which has broader functionality and increased operational safety, reduces the possibility of a collision of rolling stock at the station, due to erroneous actions of the driver and dispatcher, when the train follows a station traffic light with a prohibiting signal.

The structural diagram of the inventive device for preventing collisions of rolling stock at the station is shown in Fig 1.

The device comprises a locomotive block 1 of the train motion parameters sensors connected to the first input of the train motion control program block 2, the output of which is connected to the electropneumatic valve 3 of the rolling stock brake system. The second input of the train control control unit 2 is connected to the output of the driver’s alertness confirmation unit 4, and the third and fourth inputs and the first port are connected, respectively, with the outputs of locomotive receivers of continuous 5 and point 6 inductive communication channels and with the transceiver port 7 of the radio communication channel. Locomotive receivers of continuous 5 and point 6 inductive communication channels, by their inputs, are connected to the corresponding outputs of stationary transmitters 8, 9 of inductive communication channels. The locomotive transceiver 7 of the radio communication channel is connected by its port to the port of the stationary transceiver 10 of the radio communication channel. In this case, the stationary transceiver 10 of the radio communication channel, through the stationary unit 11 for automatic control of the interaction protocol of the dispatcher and train drivers, is connected to the stationary dispatching unit 12 of the control.

The operation of the device is as follows.

When the train moves to a closed traffic light (not shown), the program block 2 controls the movement of the train, based on the data received from the block 1 of the sensor parameters of the train’s movement, as well as from transceivers 5, 8 continuous and 6, 9 point and inductive communication channels, provides aiming stop in front of the mentioned traffic light and prohibits further movement until obtaining permission from the dispatcher.

The locomotive security system has a strict algorithm for constructing an allowable speed curve to zero, in front of a traffic light with a prohibiting signal. In this case, no actions of the driver, in particular, through the vigilance confirmation unit of the driver 4, can lead to the passage of a prohibitory signal.

The driver, through the program block 2 for controlling the movement of the train and then, through the transceiver 7 of the radio channel, sends to the dispatcher, predetermined by a special protocol, a sequence of requests and answers to obtain permission from the dispatcher to start and enter the station. The dispatcher, for permission to start and enter the station, sends the train engineer a sequence of requests and responses predefined by a special protocol. Information is sent from the stationary dispatching control unit 12, through the block 11, automatic control of the protocol of interaction between the dispatcher and train drivers and the stationary transmitter 10 of the radio channel.

On a locomotive, automatic control of the interaction protocol between the dispatcher and the driver is carried out by the train control program unit 2, which interacts with the locomotive transceiver 7 of the radio channel through its first port. If the protocol check was successful at the dispatcher and at the driver, the program block 2 for controlling the movement of the train switches to a mode that ensures further movement of the train in the manner established for this case. Otherwise, the train remains stationary due to the shutdown of the electro-pneumatic valve 3 of the brake system of the rolling stock by the train control program unit 2. In any case, the dispatcher and the driver receive an indication of the status of the current moment from their display devices (not shown).

This construction of the device expands the functionality of its use at the stations when organizing traffic for receiving and sending trains from all station tracks, while maintaining a high level of traffic safety.
