System for automatic control of the braking of a train operates as follows.

The system works in conjunction with automatic locomotive signaling (ALS), electrical interlocking (EI) and centralized Autolock (tsab). Her work makes use of information about the length and the profile path in the zone of convergence of the obstacle, and information about the performance characteristics of the brake means of the train. Compared to using only ALS system driver and the braking system receives data for the optimal choice of levels of service braking. When reaching the maximum speed first off the rod and then in case of further increasing the speed (for example, on a steep downhill) provides power to the valves 15 brake and release the brake of the train system to implement the settlement stage of braking. After reduced the I speed up software, the value of which is continuously calculated by the block 8 software speed, braking is terminated. The original data on block 8 software speed come from a 5 meter road, unit 2 information reception unit 9 automatic locomotive signaling, 10 meter performance brakes, block 11 ROM, meter 12 acceleration meter 6 speed and RF modem 20 of the locomotive.

Mounted on buochs of wheel 3 sensor 4 angle produces a constant number of rectangular pulses for each revolution of the wheel. On the basis of the total number of generated pulses to match the diameter of the brace of the pair of wheels 3, 5 meter path specifies the path traveled by train. Meter 6 speed pulse frequency from the sensor 4 of the angle of rotation determines the actual speed of the train. After passage of each of the driving measurement of distance traveled from the beginning. Information about the data track sections and the permanent speed limit is written before the trip to the database, which is stored in the ROM block 11. Using the connection with the locomotive through a half-duplex radio channel 21 digital communication allows us to simplify the travel of the device by eliminating inductive loops and travel generators for their power supply and operative to transmit information over the air. In which the system provides the transmission of temporary speed restrictions (for example, associated with renovations, or unexpected noise movement) at any point in the path of the train on the stretch, which allows to optimize the modes of motion of the train when the current operational environment and avoid unnecessary emergency braking.

The transmission of information to the locomotive on the room block and each track circuit is made through a half-duplex radio channel 21 digital communication and channels inductive coupling locomotive with track circuits.

When the device tsab fixed path receiver next track circuit driving the introduction to this track circuit train, on-Board unit 20 is assigned a temporary individual number to implement radio communication with the stationary transceiver 17 station of departure through individual half-duplex digital channel 21 communication. For the formation of the rooms are the individual room-mentioned track circuit and the number of driving that stand out on the locomotive of the code signal generated by the track circuit equipment and received through the inductive coupling antenna 1 unit 2 admission information. Unit 2 admission information transmits the selected code with his second output for generating and assigning a unique radiates in the on-Board unit 20. When TSA is building to the next track circuit this address is changed in accordance with the new number of the next track circuit. When reaching the track circuit relating to the terminal apparatus tsab receiving station, stops the action of the stationary transceiver 17 the departure station and starts the action of the stationary transceiver 17 receiving station. The transceiver unit 17 each station to communicate always calculates the current radiates on-Board units 20, the receiving device tsab information about the number of people employed by the relevant train track circuits.

When the device tsab is fixed on the corresponding path receiver entry of a train on rail chain drive, with this train set continuous communication on the individual half-duplex digital radio 21 communication and information is sent, containing the exact time classes, this room and the next track circuits, coordinates their boundaries, location coordinates, speed limits and permissible speed for these coordinates. Establishing radio communication is possible only when the coincidence of the addresses generated at stations and on Board trains. Therefore, each side unit 20 receives information that is intended only to him, and the stationary transceiver 17 determines the on-Board unit 20, from which the received response information. Information of the radio channel has priority, compared to the information, recorded in the ROM block 11 before the trip.

As part of the information transmitted by the movement of the boundaries of the track circuit, is transmitted also label the actual system time, which serves for adjustment of determining the coordinates of the location of the train on the track circuit, since accurate determination of the passage of the boundaries of the block sections locomotive driver 16 of the boundaries of the block sections, fixing the change singlegroup code signal from the track circuit, is delayed relative to the fixation time training track circuit path receiver. Also delayed the formation of radiates RF modem that is installed after the beginning of the reliable reception of codes from the next track circuit.

Thus, the present invention improves reliability and allows to optimize the modes of conducting the train. The use of the system for automatic control of the braking of a train improves traffic safety and work culture of the driver due to the automatic service brake the train to a predetermined speed and precise stopping of the train in front of the closed traffic lights.
