Description

The invention relates to automatic locomotive signaling and can be used in areas with automatic and semi-automatic blocking with pre-input - and without pre-entry coding. The purpose of the invention is to improve the safety of trains.

The drawing shows the block diagram of the device.

The locomotive signaling device for the section with semi-automatic blocking contains locomotive equipment 1 containing radio receiver 2 connected to decoder 3, register 4 of train number connected to the first input of comparator 5, the output of which is connected to the input of time relay 6, output connected to the first inputs shaper code 7 and the element And 8, the output of which is connected to the input of the signal unit 9 and the first input of the element OR 10. Locomotive receiver 11, the output is connected to the unit 12 locomotive signaling and the first output of which is connected by the second input of the element OR 10. The track equipment 13 contains a coding unit 14 connected via a rail circuit 15 to a track receiver 16, the output of which is connected to the first input of the encoder 17, the second input connected to the output of the register 18 of the train number, and output - to one input of the radio transmitter 19, the other input of which is connected to the output of the traffic light automation unit 20.

The device works in the following way.

Before opening the output signal, the attendant at the station is existing, they are associated with the attendant of the next station where the train should go, and transmits the necessary information to it, including the number of the train to be sent to the section with semi-automatic blocking. The duty station at which the train is expected to arrive sets this number on register 18, the state of which is encoded by encoder 17. As soon as the output signal for the train opens and then overlaps, after the locomotive has passed the output traffic light, the signal at the exit of the traffic light 20 turns on which will allow the operation of the radio transmitter 19. At one input of the radio transmitter 19, the code from the output of the encoder 17 will be received in the case that the track receiver 16 is turned on, which corresponds to the health of the track circuit 15. Since the paths second receiver 16 mounted on the input signal at a distance of not less braking of the train path, the train left on land, it can be moved to track receiver 16 without limiting speed. The radio transmitter 19 begins to emit a code signal in the air. Code signal

contains information about the number of the train. The power of the radio transmitter 19 is such that the radio receiver 2 receives this signal even if the locomotive (train)

still located at a nearby station. Consequently, the train, whose number is set by the driver on register 4, as soon as the open output traffic light follows, will receive its code 2 signal coming from the neighboring radio receiver 2

stations by radio where the train should be. Provided that this code signal is correctly received by radio receiver 2 of locomotive equipment 1, correctly decoded by decoder 3, a coincidence occurred in the comparison block 5 of the information entered by the driver in register 4 of the train number and coming from the station where the train should go, at the output of the block Comparison 5 shows the signal acting on time relay 6 and turns it on. If the station tracks of the station are encoded, then when opening the output signal at the second output of block 12, a signal is sent that goes to the second input of element 8. As time relay 6 has turned on, the inputs of element 8 are

a coincidence will occur, and from its output the signal through the element OR 10 will go to the second input of the code 7 generator and will give permission for its operation. Since the time relay 6 is on, and it informs

that the track apparatus 13 is functioning, the information about the train number received by locomotive apparatus 1 is correct and, in addition, received after the train leaves the traffic light, it turns on shaper code 7, at the exit

which is a green fire code signal with a carrier frequency equal to the signal frequency in the track circuit 15 with pre-input coding. The signal level at the output of the code generator 7 is determined so that the voltage of the signal at

The output of the locomotive receiver 11 was equal to (1.2-1.4) the response voltage of the locomotive signaling unit 12.

At the same time, the green light on the locomotive traffic light of block 12 continues to light up and, in addition, an additional signal lights up on the signal block 9, which notifies the driver that he is moving along the section where there is no code in the rail line and information about the freeness of this rail line arrives over the air. In this case, the control of speed and vigilance on the locomotive is disabled, and the driver also leads as in the section with an automatic blocking, where the length of the block - section is determined by the length

the path from the output signal of the station from which the train departed to the track receiver 16 installed at the beginning of the approaching section of the station where the train is taking.

In order for the radio transmitter 19 to be used to transmit messages by voice, the code to locomotive equipment 1 is pulsed, the step between the individual messages (pulses) of the code is less than the slowdown time to turn off time relay 6 locomotive equipment 1. In case of failures, the locomotive radio receiver 2 is not radio signal 19 time relay b after

The green light code signal from the generator code 7 output is shown on Vits. As soon as the train enters the station approaching area, track receiver 16 is turned off, as the locomotive wheels shunts the rail circuit 15. Signal off track receiver 16 is signaled on track equipment 13 and the encoder is turned off 17, thus, the transmission of the code over the radio channel to the locomotive is discontinued. The shutdown equipment 1 is disconnected in this case. In this case, the driver will turn off the specified time in a given time. time 6

code 7 and turn off the signal unit 9. and the code signal will stop

In the absence of a signal at the inputs of the loco from the output of the code 7 generator, but so

motive receiver 11 will occur through a coded circuit in the track circuit

some time switching unit 12 signal, which determines the indications

the locomotive signaling to the white fire 5 of the station's traffic lights, the locomotive locomotive traffic light, simultaneous receiver 11 will receive a code signal. Including periodic control, alert is from the rail circuit 15, and the 12-driver unit and, if necessary, the locomotive speed control will switch speed control. This state of the block 2 is a motive traffic light for red-yellow or

notifies the driver that he is a yellow light or will keep the indication green to be particularly vigilant, since it is not known for what reason the code did not receive over the radio channel (due to interference during transmission in the radio channel, radio receiver 2 or refusal

depending on the traffic light indication. But in this case, the signal unit 9 will turn off and notify the driver that he has entered the station approaching station and the indication of locomotive track equipment 13, or the failure of a local traffic light determines the indication of the input-motive equipment 1). But such a state of traffic light. In case of failure of the locomotive

The block 12 of the locomotive signaling, as well as on the section with automatic blocking, is emergency and therefore requires increased vigilance from the driver. If the switch is 30

equipment I driver leads the train on the site without ALSN, as in the case of automatic blocking, namely, by the dispatch order with heightened vigilance. The same driver leads the train and in case of failure of the track equipment 13, this is equivalent to the failure of locomotive equipment 1, since the code signal from the radio transmitter 19 will not reach the locomotive, which, in turn, will not turn on

If block 12 turns on the white light of a locomotive traffic light due to interference in the radio channel, then after some time the noise relay 6 stops turning on again, because radio transmitter 19 pulses the codes to the locomotive. ,.,.

The motive is independent of the functioning of loco-relay 6 and, therefore, on locomotive equipment 1, since the train still has no traffic lights on block 12 of the locomotive and has not entered the signaling station of the signaling station on a white light. In the ca- and track apparatus 13, the locomotive and station radio station functions correctly, and block 12 switches, as the stations can receive a radio station signal from the second output of block 12 through to the type “Transport that contains OR 10 saves letting the locomotive, besides the radio, allow the code 7 generator, which is registered with train number 4, the decoder 3, will wait for the relay to turn on again, the comparison unit 5, and at the station, time 6, then at the additional radio transmitter 19, the register input locomotive receiver 11 innomers of the train 18 and encoder 17.

depending on the traffic light indication. But in this case, the signal unit 9 will turn off and notify the driver that he has entered the station approaching area and the indication of the locomotive traffic light determines the indication of the input traffic light. In case of failure of the locomotive

equipment I driver leads the train on the site without ALSN, as in the case of automatic blocking, namely, by the dispatch order with heightened vigilance. The same driver leads the train and in case of failure of the track equipment 13, this is equivalent to the failure of locomotive equipment 1, since the code signal from the radio transmitter 19 will not reach the locomotive, which, in turn, will not turn on

. ,.,.

time relay 6 and, consequently, at the locomotive traffic light of the block 12 of the locomotive signaling, according to white light. As a locomotive and stationary radio station, a radio station of the type Transport can be received, which contains, besides the radio receiver, the train number register 4, the decoder 3 and the comparison unit 5, and at the station, except the radio transmitter 19, train number 18 register and encoder 17.
