Description

The invention relates to railway automatics and telemechanics, in particular to devices for interval control of train movement. A device containing a transmitter mounted on a locomotive and installed on the first track is known. and the second receivers connected by inputs to the rail yarns and the outputs respectively by the first and second speed measurement units of the first and second trains respectively and with the inputs of the first and second, the coordinates of the first and second trains respectively and the command generator lj. A disadvantage of the known device is that the convergence of trains occurs without taking into account the mutual coordinates and BRAKES; paths, which limits the possibility of increasing the capacity of the line. The purpose of the invention is to increase the capacity. . To achieve this goal, a device containing a transmitter installed on the locomotive and first and second receivers installed on the track, connected by inputs to rail lines and outputs, respectively, to the first and second speed measuring units of the first and second trains, respectively, and to the inputs of the first and second the units determine the coordinates of the first and second trains, respectively, and the command generator, is equipped with a block of impact braking, connected by an input with the output of the second velocity measuring unit , the first and second programming blocks of the speed, respectively, of the first and second trains, a coordinate subtraction unit, connected by inputs to the target braking coordinate output, and to the output of the first coordinate determination unit of the first train, and output to the input of the first speed programming unit of the first train, first and the second comparison element and the coincidence element of the connected output to the command generator, and the first and second inputs to the outputs of the first and second elements respectively and, the first inputs of which are connected respectively to the outputs of the first and second speed measurement units of the first and second trains, respectively, and the second inputs respectively to the outputs of the first and second speed programming units, with the output of the second coordinate determination unit of the second train connected to the input of the second unit programming speed of the second train. The drawing shows the functional diagram of the device. The device consists of a transmitter 1 installed on the locomotive, connected via a rail line 2 with the first receiver 3 or via a rail line, 4 with a second receiver 5. The output of the first receiver 3 is connected to the first speed measurement unit 6 and the first coordinate determination unit 7, and the output the second receiver 5 - to the unit 8 for determining the coordinates to the unit 9 for measuring the speed. The block 10 coordinates the target braking input is connected to the output of the block 8 of the second train and the input of the block 11 of the speed programming, and the output is connected to the input of the block 12 of the subtraction of coordinates, the output of which is connected to the block 13 of the programming of the speed of the first train. The first input of the comparison element 14 is connected to the output of block 11, the second; the input is to block 9 for measuring the speed of the second train, and the output is for the first input of the element {15 coincidence, the second input of which is connected to the output of the comparison element 16 connected by the first input to the measuring unit 6 of the speed of the first train, the second input to programming 13 speed of the first train, and access to the generator 17 teams. The device works as follows. Transmitter 1 transmits train speed information from an axial sensor. Receiver 3 receives information from the rail yarn 2 from the first train. Receiver 5 receives information about the speed of the second train through line 4. From the output of the first receiver 3, DC pulses are fed to the input of the train 7 unit for determining the coordinate of the first train and the input of the velocity measuring unit 6. From the output of the second receiver 5, the DC pulses transmitted by the second train arrive at the input of the second train determining unit 8 and the input of the second train speed measuring unit 9. When the second train reaches the minimum train (for example, 0.15 m / s), after the train leaves the station, the target braking coordinate unit 10 is included, which is a corresponding block that determines the stopping point of the second train in case of an emergency stop while the train is moving along the program line. curve with the speed coming from block 9 measuring the speed of the second train. From the output of block 7, determining the coordinates of the first train, information about the coordinate of the first train arrives at the first input of block 12 of the coordinate subtraction, and the second input receives information from block 10, the coordinate braking coordinate about the coordinate of the stop point of the second train in the case of an emergency stop. trains taking into account the stopping distance of the first train during emergency braking and when it is moving at a programmed speed. The difference coordinate from the output of block 12 of the subtraction of coordinates is fed to the input of block 13 of the programming of the speed of the first train, where the correspondence between the coordinates of the trains with the programmed check is checked, and if the interval decreases less than permissible, a single signal at the output of block 13 does not appear. If the movements of both trains are in accordance with the program, the programming unit 13 of the speed of the first train produces at its output a single signal. Ilpif the occurrence of signal 7164 on both inputs of comparing element 16, a single signal appears at its output, indicating that the first train has completed the approach program. In block 11 of the programming of the speed of the second train, the consistency of the motion of the second train with the pledged speed is checked, the block 11 of the second train is a correspondence block, where each value of the distance covered corresponds to a certain speed (program speed). Comparison element 14 generates a single resolving signal at its output when the second train is moving at a speed greater than software, i.e. The number of pulses from block 9 measuring the speed of the second train is greater than the number of pulses from block 11 programming the speed of the second train. When appearing on both inputs of the element 15, the permitting signals appear at its output, the command canceling the speed limit issued by the command generator 17, when one of the enabling signals hits, the cancellation command does not appear and the control is performed by the signals of the automatic locomotive signal . The use of the proposed device makes it possible to reduce the interval of passing trains, which allows increasing the capacity of the section by 10-15%.
