A disadvantage of the known technical solution adopted as a prototype is the danger of collision of trains at stations not equipped with a system such as LITTLE or similar, for parallel hostile routes, due to the fact that within the section, before a closed traffic light at the station, the driver mistakenly accepting the opening of someone else's traffic light, for example, a shunting traffic light on a parallel path, for opening the shunting traffic light of its route and starting to move, a closed traffic light of its path can pass from the small move and take the arrow of a hostile route, creating a dangerous situation.

The technical result of the utility model is to increase the safety of train traffic by eliminating the possibility of dangerous collisions of moving units, due to the passage of a closed station signal at stations not equipped with a LITTLE system or similar, providing automatic targeted stopping of a train in front of any traffic light with a prohibiting signal indication and subsequent prevention of its passage.

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 train control software block, the output of which is connected to an electropneumatic valve of the rolling stock brake system, a second input of a motion control software block 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 to the locomotive receivers of the continuous and point inductive communication channels and the transceiver port of the radio communication channel, the locomotive receivers of the continuous and point inductive communication channels with their inputs are connected to the corresponding outputs of the stationary transmitters of the inductive communication channels, the locomotive transceiver of the radio communication channel is connected by its port to the port of the stationary radio transceiver through a stationary unit for automatic control of the dispatcher interaction protocol and for train drivers, it is connected to a stationary dispatching control unit connected to electric centralization means, according to the proposal, a block for setting the sequence of allowed routes and a unit for determining the presence of hostile routes, the input / output of which is connected to the additional output / input of the unit, are inserted and connected to the stationary dispatching control unit automatic control of the protocol of interaction between the dispatcher and train drivers, and the output of the control unit is connected to the input of the station molecular transceiver radio bearer.

The drawing shows a diagram of the proposed device to prevent collision of rolling stock at the station.

A device for preventing a collision of rolling stock at a station contains a block 1 of train motion parameters sensors connected to a first input of a train motion control program block 2, the output of which is connected to an electropneumatic valve 3 (EPC) of the rolling stock brake system, a second input of a train motion control program block 2 connected to the output of the driver vigilance confirmation unit 4, and the third and fourth inputs and the first port are connected respectively to the outputs of the locomotive receivers 5 and 6 point inductive communication channels and a transceiver port 7 of the radio channel, locomotive receivers 5 and 6 of the continuous and point inductive communication channels with their inputs are connected to the corresponding outputs of the stationary transmitters 8 and 9 of the inductive communication channels, the locomotive transceiver 7 of the radio channel is connected with its port to the port of the stationary transceiver 10 of the radio communication channel, which through the stationary unit 11 of the automatic control protocol of the interaction of the dispatcher and train drivers connected to a stationary dispatching control unit 12 connected to electric centralization means, to a stationary dispatching control unit 12 connected to the block 13 setting the sequence of allowed routes and block 14 determining the presence of hostile routes, the input / output of which is connected to the additional output / input of block 11 of the automatic protocol control interaction of the dispatcher and train drivers, and the output of the control unit 12 is connected to the input of the stationary transceiver 10 of the communication radio channel and.

A device for preventing collision of rolling stock at the station operates as follows.

When the train moves to a closed traffic light (not shown in the drawing), the program block 2 controls the movement of the train, based on the data received from block 1 of the sensors for the parameters of the train’s movement, as well as from transceivers 5, 8 of continuous and 6, 9 point and inductive communication channels, provides an aimed stop in front of the mentioned traffic light and prohibits further movement until permission is obtained 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 the 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, transmits to the dispatcher, predetermined by a special protocol, a sequence of requests and responses to obtain permission from the dispatcher to start. The dispatcher, in order to permit the start-up mode, transmits to the driver, predetermined by the mentioned protocol, a sequence of responses and requests corresponding to the current operational situation. Information is transmitted from the stationary dispatching control unit 12 through the block 11 of the automatic control protocol for the interaction of the dispatcher and train drivers and the stationary transmitter 10 of the radio channel.

On the locomotive, the control protocol for the interaction of the dispatcher and the driver is automatically controlled 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 on the corresponding display devices (not shown in the drawing).

At stations that are not equipped with a shunting automatic locomotive signaling system or similar, unlike the prototype, when controlling the start of a given train, after the traffic light of its route is opened for it, the absence of train movement on routes hostile to the route of this train is additionally checked for which, at this station, there is a risk of erroneous visual perception by the train driver of this train of their permissive signal indication instead of the signal indication of a traffic light with oego route traffic. For example, such traffic lights can be shunting traffic lights on the routes of neighboring railway tracks. For this, the blocks 2 for controlling the movement of all trains are interrogated by the stationary dispatching unit 12 of the control through the block 11 of the automatic control protocol for the interaction of the dispatcher and train drivers and the stationary transmitter 10 of the radio communication channel.

Upon receipt of information according to the protocol that differs from the established one and corresponding to the presence of hostile routes, block 14 fixes the presence of these hostile routes and generates a corresponding signal to the stationary dispatch control unit 12, which generates a light signal signal displayed on the information board (not shown in the drawing ) in the form of, for example, a flashing red signal, or an audible alarm can be implemented. Additionally, the control unit 12, according to the data received from the electric centralization means, generates a command to stop the train, the information from the locomotive of which differs from the standard one according to the protocol, and transmits it to the locomotive directly through the stationary transmitter 10 of the radio communication channel. Upon receipt of information about the movement of at least one of the trains on hostile routes, the permission to move this train, despite the open traffic light of its route, is delayed until the forced braking and stopping of trains located on hostile routes. Forced braking can be performed by stop commands transmitted through the stationary transmitter 10 of the radio channel. At the same time, information on the significance of the allowed routes (connection to the sent train, supply of cars for loading (unloading), leaving at a standstill, etc.) is entered into the block 13 for setting the sequence of allowed routes. Block 13 provides information in the form of a table or a list of the sequence of passes of trains (locomotives). This information enters the control unit 12 control, which generates at its output an information signal about the sequence of pulling along parallel routes, which using stationary transceiver 10 of the radio channel is transmitted to locomotive drivers.
