Abstract

The invention relates to railway automation and telemechanics, namely to locomotive signaling devices. The purpose of the invention is to increase reliability. Each block 15-18 of the last carriage of the train is an automatic switch that provides three states: disconnected, if there is no train within the track circuit, the input is connected to the first exit when the last car is completely within the given track circuit the exit to the other phases of the train train run. If there is a speed limit within this track circuit 2, then there will be no signal at the output of generator 11 due to the presence of a ban on AND 14. When generator 11 operates to transmit the main signaling, i.e. the rail circuit 2 is occupied by the first car of the train, the control circuit will be closed, i.e. There will be no speed limit. 1 il.

The signal currents, through inductive coupling, perceive the receiving and deciphering unit 20 of the first carriage moving train. The reception of code signals from each rail line occurs during the time that the first car of the train remains within this rail line. The receiver-decryption unit 20 of the train, the first car of which is located within the rail circuit 3, receives, by inductive coupling, the signal currents from the generator 12, the code of this rail circuit. The received and decrypted signal from the output of block 20 goes to the first signal control unit 22, which signals the machine about the current allowable speed; i automatic motion control on the basis of the information coming from the path

The rail stump 2, within which the last car of the train is located, also receives a signal current from the generator 3 of the code signals of the rail line 4, which is next in the direction of travel relative to the rail circuit 3 occupied by the first car of the train. Therefore, generator 13 generates code signals that are trainable for the train, i.e., carry information about the upcoming allowable speed of movement within the next track circuit 4. From the output of code signal generator 13, alarm signal current to the input end of the rail line 1 enters through the closing contact 9.1 of the track receiver of the rail circuit 4 through the circuit .: input - the second output of the last train carriage 16 detection unit, input - the first output of the last carriage detection unit 15 Here, the input end of the rail circuit 2. Each block 15-18 for detecting the last car of the train is an automatic switch that provides three states, depending on the train occupancy of the rail circuits, if there is no train within the rail circuit with the first exit when the last car of the train is located completely within a given track circuit, the connection of the entrance with the second exit to the remaining phases is to occupy the train of this track circuit.

Due to the considered property of the blocks detecting the last car of the train during the movement of the train at each moment of time, the output of the code signal generator, which is precautionary with respect to the track circuit, is detected by the first train of the train and is connected to the input end of the track circuit within which the last car of the train whatever

of the number of rail chains simultaneously occupied by train

If such a transmitting generator is a generator related to the track circuit, within which there is a limitation of the permissible speed, for example, generator II, then there will be no signal at the input of the maximum permissible generator speed due to the presence of an interdiction on the And 4 element.

This eliminates the possibility of transmitting a code signal of the maximum allowable speed. When generator P operates to transmit the main signal, ie rail circuit 2 is occupied by the first car of the train, said control circuit 2 will turn out to be closed, that is, there will be no limit on the speed limit.

The signal current of the warning code signals transmitted from the input ends of track circuits, for example, 2, inductively detects an additional receiving-decryption unit 21 located in the last carriage of the train. Processed in block 21 before

Viral signals come from its output in line 23. an intra-train connection, and from it to the second input of the signal-carrying unit 22. Thus, at each moment of time, the inputs of the signal-execution unit 22 from the outputs of the blocks 20 and 21 simultaneously arrive signals of the main and warning alarms. At the same time, in places where the speed of movement is restricted, the indications of warning signaling do not exceed the speed value of the indications of the main signaling
