The invention relates to railway automation and telemechanics, in particular, to devices for automatically assigning shunting routes from a locomotive during electrical interlocking.

The purpose of the invention is to increase reliability.

The drawing shows a block diagram of the device.

 The device contains a transmitter 1 located in the driver’s cabin, in which there are buttons for specifying the position of arrows, the start and end of maneuvers, contacts 2 of which are connected to the inputs of the encoder 3, the output connected via matching element 4 with an infrared radiator 5. receivers 6, each of which consists of a photo sensor 7, connected via a matching element 8 to the input of the pulse shaper 9, one output of which is connected to the input of the display element 10, and the other Is the output of receiver 6.

In addition, the device contains a switch 12 placed in a shunting column 11, which alternately connects the receiving sets to the decoder 13, the inputs of which are connected to the memory block 14 and the information inputs of the switches 15 and 16. The address inputs of the switches 12,15 and 16 are connected to the output of the pulse generator. The output of memory block 14 is connected to the input of block 18 for fixing the start and end of maneuvers. The inputs of the memory blocks 19–21 are connected to the first, second, and third outputs of the switches 15 and 16, respectively, and the outputs to the inputs of the key elements 22–24, the outputs of which are connected to the inputs of the switchboard execution units 25–27. The inputs of the display unit 28 are connected to the outputs of the blocks 18, 25-27.

The device works as follows.

The driver performs maneuvers in a small maneuvering area. Maneuvering work is small. In order to carry out remote control by an arrow, the driver first requests by radio from the station attendant. In the case of agreement, the chipboard presses the maneuver resolution button. When the maneuver resolution button is pressed, the shunting operation of the RMRS is energized, with contacts of which all arrows entering the local control area translate: transferred to the local control into a positive one, and travel and security guards to the appropriate position defining the exhaust for production.

maneuvers. At the same time, power is supplied to the apparatus located in the maneuvering column 11.

Stopping near the switch, for example 15, the driver directs the emitter 5 of the transmitter 1 through the windshield or side window of the locomotive cab towards the photo sensor 7. Accurate stopping of the locomotive is not necessary. At the same time he presses the button 2 maneuvers. In this case, pulses of a specific sequence from the encoder 3 are fed to the infrared emitter 5. IR radiation is sensed by the receiving set of this arrow, pulses are generated by the photosensor 7 by the block 9. The generated signal simultaneously arrives at the input of the multiplexer 12 of the shunting column and the display unit 1. The indicator of the display unit 10 lights up, so that the driver can be aware of the status of communication between the transmitter and receiver. Pressing these buttons is no longer necessary. Multiplexer 12 alternately connects its inputs to the output, which is connected to the input of the decoder 13.

The status information of the second inputs of the decoders is recorded in memory block 14 and stored there until it is changed.

The driver presses one of the arrow position buttons. The encoder 3 generates a pulse sequence corresponding to this command, which is emitted by the IR emitter 5 and enters the receiver 6. Then, by block 9, pulses are generated. The fact that the command is received is signaled by the indicator of the block 10. At the same time from the arrow column, the signal enters the shunting column 11 at the input of the multiplexer 12. The inputs of the multiplexer 12 are connected to the inputs of all receivers, but the signals are transmitted to the input strictly dku. The signal to transfer the arrow to the positive position is fed to the decoder 13.

With the help of demultiplexers 15 and 16, this information will be recorded in block 20, where it will be stored. Unit 20 stores information about the management of only the corresponding arrow and the normal recording mode is provided by the synchronous operation of multiplexer 12 and demultiplexers 15 and 16 using block 17.

At the end of the maneuvers with the button for ending the maneuvers, the driver sends the command to block 18

Thus, the station attendant is notified of the end of the work, thus excluding the possibility of transferring the arrows from the locomotive of the shunting column.
