The known device does not fully use the possibility of reducing the intervals between trains when they depart from the station, since in order to prepare the next departure route, the system waits for the complete release of all station track sections involved in the current departure route.

In the known system, the throughput is limited by the fact that only one train is allowed to enter the station for each receiving track. And before the train completely vacates this track, subsequent trains are prohibited from entering this track by an entrance traffic light with a red signal indication.

The technical result of the invention is to increase the throughput of the station, by reducing the interval of passing trains, both when receiving and when departing from the station.

The drawing shows a diagram of a system for regulating the movement of trains.

The system for regulating the movement of trains works as follows.

In accordance with the train situation, the block 6 for controlling and processing the logical dependencies of the centralized automatic blocking (optionally integrated into the microprocessor centralization) generates a control signal for setting the transceiver 3 to the code signal of the automatic locomotive signaling ALS (ALSN or ALS-EN systems). This code signal, when the track circuit is occupied, from the output of the block 6 is transmitted through the CAN interface 1 of the stationary equipment 2 to the input of the transceiver 3, which directly transmits the signal to the rail line. Block 6 of the control and processing of logical dependencies evaluates the train situation, free and busy track circuits and traffic lights. In particular, when generating codes for departure routes, block 6 interacts with blocks 7, 8, and 15 via the CAN interface 1 of stationary equipment 2 for section-by-section inclusion of ALS codes in sections of departure routes.

The control unit 7 for section-by-section opening of train departure routes allows the opening of a section of a route of a certain length, depending on the mode of passing trains from the station, after this section is released by the previous train to be able to use this section in the departure routes of subsequent trains.

Block 8 section-by-section inclusion of ALS codes in sections of departure routes allows the inclusion of ALS codes in the corresponding sections of departure routes after the train is authorized to enter the beginning of these sections.

If the next train in front occupies part of the sections of the station neck through which the departure route or the removal section passes, then signals about their employment are received from the output of the transceiver 5 to the input of block 6. From the output of the block 6 of control and processing of logical dependencies through the CAN interface 1 of stationary equipment 2, the signals are transmitted to the input of the transceiver 10 of the interlocking interface.

The transceiver 10 transmits this signal from its output through the relay interface 11 to the input of the device 12 for processing logical dependencies of centralization. In accordance with the train situation, the centralization logic processing device 12 controls and sets the departure routes from the station to the haul of trains.

The minimum time interval between train departures is reached when the train ahead has vacated in the neck of the station, or in the section of the removal of a section of its departure route, so that the train sending behind it can move along the newly prepared departure route at the maximum allowed speed along the turnout sections of its departure route .

Information limiting the speed of movement of the respective trains on the sections of its departure route freed from the train is transmitted via radio channel to its on-board safety device 19 through the digital communication transceiver 4.

In the on-board safety devices 19, all information about the speed limits on the vacated sections of the route of departure of the first train through the on-board CAN interface 18 enters the corresponding module 17 of traffic control on the vacated sections of the station route of departure, where, together with on-board data on the current coordinates of the location of the locomotive trains linked to the on-board electronic route map of a given station is used to calculate targeted braking curves.

The traffic control modules 17 for the vacated sections of the station route of departure during the movement of trains along the routes of departure generate commands for limiting the permissible speed of movement, priority over other commands for controlling the speed of movement generated in the onboard safety devices 19. The sections into which the interlocking logic dependency processor 12 divides the departure routes may have variable boundaries for traffic control flexibility. Therefore, when each route is prepared by the block 9 for binding the boundaries of the sections of the routes of departure to the coordinates on the electronic map of the routes of the station, the formation of data on the coordinates assigned by the device 12 for processing logical dependencies of centralization, the boundaries of the sections of the routes of departure for sending this data via the radio channel to the on-board security devices 19 before how these trains enter these sections of the route. This is done so that the real-time motion control module 17 can calculate the corresponding targeted braking curves.

To improve traffic safety, along with information about speed limits, ALS station devices also transmit to the track circuits of free sections of departure routes information about the identification of the track occupied by the train and the number of the train to which these signals are intended.

According to a periodic control signal, the onboard safety device 19 transmits a message about the content of the received ALS signals to the station digital communication transceiver 19 through the transceiver of the onboard device.

Information from the transceiver 4 comes from its output through the CAN interface 1 of the stationary equipment to the input of the block 6, which also receives information from the output of the transceiver 5 about the current release of sections of the train departure route for the following trains.

Block 6, on the basis of the received information, generates a control signal to change the signal indications of the corresponding traffic lights, limiting the vacated sections of the departure route to a special signal indication.

This signal from the output of block 6 is fed through the CAN interface 1 of the stationary equipment 2, to the first input of the transceiver 10, from the second output of which, through the relay interface 11, it is transmitted to the input of the device 12 for processing logical dependencies of centralization. From the third output of the device 12, the signal is transmitted to the input of the block 14 for switching on the additional signal indication of the output traffic lights in order to allow traffic in sections limited by these traffic lights only according to the signals generated by the on-board train safety device 19, for example, with an allowable speed of 25 km/h with the provision of a train stop in front of the protective section of the track, which limits the permissible approach to the train in front.

The device 12 for processing logical dependencies of centralization also performs control and installation of receiving routes to the station from the haul. At the same time, its fourth and fifth outputs, respectively, control the block 20 for turning on the input traffic lights and the block 21 for turning on the additional signal indication of the input traffic lights of the train reception routes. During the train's entry into the station, when its locomotive 16 approaches the input traffic light, a communication session is established between the locomotive transceiver and the transceiver of stationary equipment 2 via a digital radio channel. train, about the number of axles in this train, the length of its composition, and also information about the route of the train through the station.

Then there is a session of radio exchange of information between the transceiver 24, which is connected to the axle counting unit 23 and the transceiver of the onboard safety device 19 of the locomotive 16 approaching the unit 23.

The session occurs for a few seconds before locomotive 16 passes the entry light. For communication via a digital radio channel with the transceiver 24, the transceiver of the locomotive 16 loads its address from the electronic route map located in the electronic memory of the onboard safety device 19. During the radio exchange of information, the transceiver of the locomotive 16 loads into the memory buffer of the transceiver 24 the number of a priori known number of axles in the train. As each wheel of the train passes over the sensor for fixing the passage of the wheel of the axle counting unit 23, the number in the memory buffer of the transceiver 24 decreases by one, and when the number reaches zero, a signal is generated for the correct completion of the axle count. The transceiver 24 transmits this signal via a digital radio channel to the transceiver of the on-board safety device 19 of the locomotive 16 and further from it via the second digital radio channel to the transceiver 4 of the station equipment and serves in the system as a sign of the train in full train. In the process of axle counting, information redundancy is used to reduce the probability of errors.

Block 23 counting axles performs the function of a virtual route traffic light without interfering with the alteration of electrical interlocking. The locomotive 16 of the first train enters the track under the yellow signal of the input traffic light, which then changes to a red signal, and then this locomotive 16 follows the ALS signals from the track circuits, and the locomotive 16 of the train following it enters this track under the white cross signal at the entrance traffic lights and moves along the segments of the route, permitted by orders, allocated by the on-board train safety device 19 from digital messages received via the second digital radio channel from the station transceiver 4. The signal indication in the form of a white cross is turned on at the traffic light every time after the next train has passed this the traffic light is in full force and has moved away from the traffic light at a distance that allows safe entry to the same track of the train following it. The calculation of this removal distance is performed by stationary equipment 2, which uses data on the current coordinate of the locomotive 16 of the train, determined by the satellite navigator of the on-board device 19 of the safety of the train, as well as data on the length of the train. The cross-shaped signal at the input traffic light indicates to train drivers the permitted mode of movement along the path behind the input traffic light, according to the signals generated by the on-board safety device of their train, while the train braking curve, within each section of the receiving route, is calculated by its on-board safety device 19, taking into account initial information extracted by the onboard safety device from digital messages received via the second digital radio channel.

The input traffic light signal in the form of a white cross receives energy from the same power source as the red traffic light signal. In this case, the switching of the power supply circuits of these signals is carried out in electrical interlocking. The axle counting unit 23 and the transceiver 24 are powered by the same energy. A sign is transmitted via the second digital radio channel from the electrical interlocking to the locomotive 16 to display on the display of the on-board device 19 of the train safety situation when the input traffic light acts as a virtual route traffic light together with the axle counting unit 23 . The location of the axle counting block 23 on the route map is displayed in this case as a virtual route traffic light.

Thus, the proposed system provides a further increase in throughput by reducing the passing intervals between trains when receiving and departing trains at the station.
