This invention relates to a device; railway automation and telemechanics, in particular, on subways. A device for controlling the movement of a metro train is known, which contains an automatic signal generator and an automatic speed control signal generator installed on the track and connected to a track circuit, and a locomotive receiver connected to the auto-knowledge signal decoder and automatic speed control signal decoder on the locomotive, one output of which connected to one input of the braking unit, the other: the input of which is connected to the output of the speed measuring unit, a confirmation block neither: watchfulness, rheostat position sensor; A controller and an executive unit connected by its inputs to the outputs of the auto-knowledge signal decoder 1. A disadvantage of the known device is the inability to centrally control the actions of the driver for controlling rolling stock, especially when driving a train by one driver. The purpose of the invention is to increase the efficiency of train traffic control. The goal is achieved by the fact that a device for controlling the movement of a metro train, containing a car carrier signal generator and an automatic speed control signal generator installed on the track and connected to a track circuit, and a locomotive receiver on the locomotive, connected to the auto learning signal decoder and an auto signal decoder on the locomotive speed, one output of which is connected to one input of the block, braking, the other input of which is connected to the output of the measuring block neither the speed, the vigilance confirmation unit, the rheostat controller position sensor and the executive unit connected by inputs to the outputs of the auto-knowledge signal decoder are equipped with AND elements, time blocks, OR element, encoder and train number input unit connected with the output of one encoder input, the output of which it is intended to be connected to receiving and transmitting devices, and the other input is connected to the output of the OR element, each of the inputs of which is connected respectively to the output of each element AND, n The first inputs are connected to the output of the position sensor of the rheostat controller, and the second inputs are connected to the output of the vigilance confirmation unit, the third input of the first element I is connected to one output of the auto-knowledge signal decoder through the first time delay block, the other output of which is connected to the third input of the third element And, and the output of the decoder of the automatic speed control signals is connected to the fourth input of the first element And directly and through the third the time delay unit with the third input of the second element I, the fourth input of which is connected to the output of the braking unit. The drawing shows a functional diagram of the proposed device. The device consists of frequency generators 1 and 2 of the auto command commands and an automatic speed control system (APC) of the rail circuits 3, a locomotive receiver 4 frequency signals of the track circuits, decoders 5 and 6 of the auto command commands and the APC system, the executive unit 7, the speed meter 8, unit 9 APC dodging, sensor 10 of a rheostat controller (RK), vigilance confirmation unit 11, time delay blocks 12, 13 and 14, elements 15, 16 and 17 AND and element 18 OR, encoder 19 associated with transmitter 20 of the train station; at the central control station of the receiver 21, the decoder 22 connected to the display unit 23 and to the encoder 24 connected to the psrlsg;;: iku 25 stationary radio; receiver 26 on. The locomotive of the train radio is connected to the decoder 27 connected to the block 28 for entering my room number. After the train stops at the station while stationary, the frequency generator of 2 APC commands sends to the track circuits 3 cHrHa .., iVg about the permissible speed of movement, which through locomotive receiver 4 enters the decoder b of the APC system commands. With Vfi O, the signal "1." Appears at the output of the decoder 6. At the time of the graphic departure of the train from the station, the frequency generator 1 of the auto command commands sends to the track circuits 3 a triggering command, which through the locomotive receiver 4 is fed to the input of the decoder auto command commands, which at the first output gives the signal "1. This signal goes to the executive unit 7 and through the time delay unit 12 (through time T) to the input of the element 15 I. During the train station at the station, the rheostat controller (RK) is in the last brake position. In this position, the sensor 10 of the position of the RK generates a signal "I. The driver’s vigilance confirmation unit 1 also issues a “1” signal at your departure, if the driver does not confirm his vigilance by pressing a special button (not shown). When confirmed by the driver vigilance

the output of block 11 appears signal "O. Thus, if during the time TI after the arrival of the drive-on command the driver does not confirm his vigilance, then the signals “1. This will result in the appearance of the signal “1 at its output, which through element 18 OR will go to the information encoder 19 on the train, and then through the transmitter 20 of the train station and the receiver 21 to the stationary radio station to the decoder 22, and from the latter to the display unit 23, through which information is transmitted to the dispatcher about the loss of workmanship by the machinist. At the second input of the encoder 19, information is received about the number of the train entered manually by the driver, which is transmitted to the dispatcher at the central control post simultaneously with the transmission of information about the status of the driver. To confirm that the dispatcher has received the transmitted information: a transfer, a receipt is provided on the reverse communication channel, for which from the output of the display unit 23 information about the train number is sent to the encoder 24, the transmitter 25 of the stationary radio station, the radio receiver 26, the decoder 27 and then to the second input of the train number input block 28, where the signal received from the central post is compared with the train number set in block 28. In case these two signals coincide, a coma is sent to the encoder 19 NDA on the termination of the transfer of the train number and the information about the loss of efficiency by the driver.

When the train is on the stretch, when the APC command “vg O” is used, the signal v О from the output of the decoder 6 of the APC commands enters the input of the APC braking unit 9, to another input of which the information about the actual speed is received from the speed meter 8. At the actual speed exceeding the permissible, block 9 outputs the signal "1 and turns on the train's brake means to a complete stop until the rheostat controller comes to the last brake position and the output of the sensor 10 of the RK position does not show the signal" 1. Simultaneously with the appearance of the signal Vd O at the output of block 6, connected to the inputs of block 13 and element 15, the signal "1 appears, which through time Tj determined by the block of time delay 13 arrives at the input of the second element 16. If time t, the machinist will not confirm

If you are alert, then all the inputs of element 16 will contain signals “1, and at its output also signal“ I. about the loss of performance of the driver, which through elements 18-22 will go to the block 23 of the display.

 In the case when the train stopped at the station and the resistor controller came to the last brake position, the signal "1." Appears at the output of sensor 10. At the same time, the frequency generator 1 of the auto-0 command commands to the rail circuits 3 a command to open the doors, which through the receiver 4 enters the decoder 5 of the auto command commands, at the second output of which the signal Cs-5 appears. 1, which through time Tz is determined by the block.m. 14 time delays, goes to another input of the 17 I. Element. If during the time Tz after the arrival of the door opening command, the driver does not confirm its operation, confirmation block 11

Q vigilance will produce a signal "1, and after time Tz, the signals" 1 are present at all inputs of element 17 I, and the signal "1" also appears at its output. This signal through the elements 18-22 enters the display unit 23, located 5 at the central control station.

After the arrival of the signals in block 23 about the loss of working capacity. The train dispatcher by the machinists takes operational measures to replace the locomotive brigade.

The device allows you to automatically detect cases of loss of health by machinists, take prompt measures to replace the locomotive crew, and also promptly identify the train number on which this event occurred.
