Abstract

The invention relates to railway automatics devices and can be used in systems of interval control of train movement, namely, to stop a train in front of a closed traffic light. The purpose of the invention is to increase reliability. The goal is achieved by the fact that when the train passes sections 16.1-16.5, each of which is connected to the resonant circuits of the LC-chains, the train will be stopped at an increased speed by emergency braking. 2 Il.

The invention relates to railway automatics devices and can be used in systems of interval control of train movement, namely, to stop a train in front of a closed traffic light.

The purpose of the invention is to increase reliability.

FIG. 1 shows a block diagram of the track elements of the device; in fig. 2 is a diagram of the locomotive elements of the device.

The device contains frequency generators 1-5 located on the path, band-pass filters 6-10, to each of which the corresponding control relays are connected: 11 with contact 11.1; 12 with contact 12.1; 13 with pin 13.1; 14c contact 14.1, 15c contact 15.1, with all the contacts included in the circuit between the rail line 16, divided into sections 16.1, 16.2, 16.3, 16.4 and 16.5, each of which are connected LC-chains, and the transmitter 17 signals of automatic locomotive signaling, The control input of which is connected to the contact 18 of the signal relay of the traffic light 19. The device also contains the relay 20 and 21 of the control code, the first of which is connected to the poles 22 and 23 of the power supply through the serially connected front contacts 24.1, 25.1, 26.1 and 1 27.1, in parallel each of which their rear contacts 24.2, 25.2, 26.2 and 27.2 of the receiving relays connected to the outputs of frequency signal receivers (not shown) are connected respectively, the second relay 21 is connected to poles 22 and 23 via serially connected front contacts 25.3, 26.3, 27.3 and 28.3, parallel to each of which are connected, respectively, their rear contacts 25.4, 26.4, 27.4 and 28.4 receiving relays. Each LC chain contains serially connected respective capacitors 29-33 and inductors 34-38.

The device works as follows.

With open traffic light 19, the contact 18 of the signal relay is closed and the transmitter 17 generates a signal of the open state of the traffic light. Relays 11-15 control the presence of signals from each of the generators 1-5, coming through filters 6-10. The signal from the transmitter 17 checks the health of all generators (pins 111 - 15.1 relay 11-15) and generators 1-5 enters the rail line. Each circuit is tuned to its own frequency and beyond the point where the loop is connected, the current of a certain frequency

does not spread. Transmitter current 17 runs along the entire rail line. With open traffic lights, one signal is sent by transmitter 17 and locomotive devices do not respond to signals from generators 1-5.

When the traffic light is closed 19 and the contact 18 is open, on arrival the locomotive receivers receive frequency signals from generators 1-5, receive receiving relays. Relays 20 and 21 are slow down. When the train enters section 16.1, the train receives a signal from generator 1 and the contact 24.1 of the relay closes, the power supply circuit of relay 20 is interrupted. If the train speed is higher, it enters the section 16.2 earlier than de-energized relay 20 and the relay is energized. The impulse operation of relays 20 and 21 indicates the movement of the train at a speed below the permissible. When the train enters on

Q interchangeable section 16.2 starts the operation of the relay 21. The violation of the pulse operation of the relay 20 and 21 indicates that the train has exceeded the permissible speed.

Thus, the train will be stopped in front of a closed traffic light.
