Abstract

The invention relates to the field of railway transport and can be used for crossings crossing the departure routes of autonomous and dispatch control stations. The aim of the invention is to increase the safety of trains and automobiles at the level crossing. When the approximation plots are free, an idleness signal is sent to the input of the station 5 monitoring control of station paths, which is then fed from the output of block 5 to block 6 by indicating the station path free and then to the control panel of the crossing signaling system and auto-barriers. When the approximation sections are busy, the signal from the decoder 1 enters the route control unit 2 and, if there is no route at the output traffic light, from the busy path is transmitted to the station path control unit 3. The signal is then transmitted to the control unit for switching on the fence of the crossing, to the block 8 for checking the conditions of the barrier of the crossing and to the console. When the switch rail circuits are free, the signal from the block 4 of checking the switch rail circuits is fed to block 8, to which block 5 must receive a signal that the tracks are not free. If it is necessary to turn on the fence from the console, block 8 receives a signal to turn on the fence. When the signals at the inputs of block 5 coincide, the turn-on signal of the restriction is transmitted to the control unit of the crossing guard. 2 Il. to (L

The second output of block 5 is connected to the first input of block 13, and the third output is connected to the input of block 6. The output of block 6 is connected to the console 12, to which the output of block 7 is connected. Inputs of block 4 is connected to the first output of block 10, the state control of the sections of approaching the crossing. The output of block 4 is connected to the fourth input of block 8, the output of which is connected to the first input of block 14 of the control of the crossing barrier. The second input of the block 14 is connected to the remote control 12. The second output of the block 10 is connected to the additional remote control 15 of the crossing signaling system and the auto barriers, which is connected to the special remote control 15 by the barrier lights to the additional remote control 15 through the control block 16 for the traffic lights and auto lights. 18, which through block 19 of the control of lamps of barrier lights are connected with the second

the input of the block 11 and the remote control 12. The output of the block 16 is connected through the block 20 of the blocking of the fence to the first input of the block 21 of the inclusion of the fence, the second input of which

is connected to the first output of block 14 via time delay block 22, and the third input is connected to the second output of block 14 directly. The first output of block 21 is associated with barrier lights 18, the second exit is connected to the third entrance

0 of the block 11, and the third output is connected to the console 12. The first output of the block 11 is connected to the second input of the block 13, and the second output is connected to the remote control 12. The first output of the block 13 is connected to the block 16, and the second output is connected to remote control unit 12. Block 22 is connected with remote control unit 12. The third output of block 0 is connected to block 16.

The device works in the following way.

In the absence of rolling stock

areas of approach to the move from block 10

0 control of the state of areas of approach to the move in the control unit 16 of the crossing traffic lights and avtoshlabaumami receive signals of freedom. At the output of block 16, the signal about the closure of the autos-barriers and

5 the switching on of the crossing signaling system is absent and the crossing is open for the passage of the autobridge transport.

From the output of block 10, the free signals are also fed to the input of the decoder 1, in which they are decoded and from the first output are transmitted to the input of the block 5 of the control of the freeness of station tracks, where they are stored. From the third output of block 5, the signals are transmitted through block 6 of the indication of the vacancy of station tracks to the console

5 12 controls of the crossing signaling and avtoshlabumi to display information on the attendant on the move, and from the second output - to the first input of block 13 of the removal of the notice. If areas of approach

0 is occupied, then from the second output of the decoder 1, the busy signals go to the input of the route control unit 2, and if there is no route assignment, the output traffic lights from the busy path are transmitted from the output of block 2 to block 3

5 control of station paths.

In block 3, these signals are memorized and transmitted from the first output to block 11 of the control of switching on the barrier of the crossing, from the third output to the first input of block 8 for checking the conditions of the barrier of the crossing, and from the second output via block 7 of the station path indication to remote control 12 for displaying information to the attendant on moving about the path. From the output of block 16 to the crossing lights and towing bars 17, a signal is received, respectively, to turn on the crossing signaling and to close the drive bars.

When the switch-track circuits are free, the signal-free signals are received in the control unit for the switch-rail circuits, and if they coincide, the signal from the output of block 4 goes to the fourth input of block 8. To the third input of block 8 from block 5, in this case there should be a signal of lack of freedom ways.

If it is necessary to turn on the fence from the console 12, the second input of the block 8 receives a signal to turn on the fence.

Only when these four signals coincide at the inputs of block 8, the signal for fencing is transmitted to the first input of block 14 for controlling the crossing barrier.

When the rolling stock enters the switch rail track and the path, the busy signals enter block 10, where they are filled, as a signal of the direction of movement and busy path. From the first output of block 10, the signal goes to block 5 and through blocks 2 and 3 to block 7. From the output of block 7, the signal goes to console 12. From the second output of block 5, the signal goes to block 13 These notices. In block 13, the signal is also memorized and fed to console 12 to additionally block the crossing in the closed state for auto-block transport and to activate an audible warning of the train entering the station.

After following the train through the station, the information about the approach areas in block 10, block 16, from console 12 and in block 13 is erased. The signals for switching on and blocking the crossing signaling and closing of the auto gates in blocks 13 and 16 and the warning signals from the console 12 are also erased.

In case of a rolling stock stop on the way, the autocamps and crossing signaling will be blocked in the prohibitory position, the sound notification on the remote control 12 will be turned on for the entire period of the path until the crossing is guarded from the side of the vehicle. The fence is made when it is necessary to open the crossing to pass the auto-block transport.

The train must be disengaged within the path, enclosed by barrier lights 18. The transfer officer on duty from console 12 is instructed to turn on the fence. From the console 12, the signal arrives at the second input of the unit 8 in the linear node 9 of the state monitoring of the station track circuits, in which the fulfillment of the fencing conditions is checked. The signal from the output of block 8 is fed to the first input of block 14, the second input of which receives a signal from the console 12. After checking these two signals, in block 14 a command is generated to turn on

fence and enters the input unit 22 time delay. In block 22, this command is delayed in time to prevent the red lights of the traffic lights 18 from turning on in front of the rolling stock due to the erroneous actions of the shift attendant.

The activation information of unit 22 is transmitted to console 12.

Checking the expiration of the time delay for switching on the fence is carried out in block 21. From the first output of block 21, a signal is sent to turn on the lights 18, from the second exit to the third input of block 11, and from the third to remote control 12. To the second input of block II through block 19, a signal is received about the health of the traffic lights of traffic lights 18. At the first input of block 11, from the first output of block 3, a signal is received that a path is missing and there is no specified route through the output traffic light. If these three signals coincide in block 11, the signal from block 13 is output to block 13, and from the second to console 12 to be shown to the duty attendant.

5 information about the fence path. In block 13, the previously transmitted signal is checked from the second output of block 5 about the busy path and from the first output of block 11 about the path fence and in case of coincidence of these signals, the commands are issued: from the first output to

0 block 16 on unlocking the closure of the crossing, and from the second to the console 12 to turn off the audible alarm notification.

In the case of a fenced crossing, when the next rolling stock approaches the station, the remote control 12 and the additional remote control 15 turn on the alert of the attendant at the crossing, the traffic gates are closed and the crossing signaling is turned on.

If, when the train dispatcher or the station attendant at the station is fenced off, has opened the exit traffic light from the busy road, the transfer attendant will receive information about this on the remote control 12 and the auto-barriers will also automatically close and the signaling will turn on. From the first exit of block 3 to the first input of block 11 a signal is received about setting the route at the output traffic light. From the first output of block 11, this signal arrives at the second input of block 13, which causes cancellation of the removal of the notice. From the first output of block 13, to block 16 a signal is received to close the automatic storage slots and switch on the crossing signaling, and from the second output to the remote control 12

5 alarm on the sound alarm. From the second output of block 11, the panel 12 receives a signal to cancel the removal of the notice.

Cancellation of fencing is as follows.

The attendant on the move, having received a notice of the next train approaching or information about canceling the withdrawal of the notification, should send a command from console 12 to cancel the barrier that goes to the second input of block 14, and from the second output of this block to the third input of block 21. Block 21 will remember this command, but it will give a streamer the goal of increasing traffic safety of trains and auto-wagon transport at the crossing, it is equipped with control units installed at the crossing, setting of routes, occupancy of station tracks, free switch rail circuits and the freedom of station tracks, the display units of the free and busy station tracks, the block for checking the conditions of the crossing and the signal decoder inform the command to turn off traffic lights 18 only Yu, whose input is connected to the output when the first input of the block 21 of the monitoring post block Neither sections of the approach to the crossing, one output is connected to the input of the control unit for the freeness of station tracks, and the other to the input of the control unit for setting the routes, the output of which

Pit signal from block 16 through blocking of blocking of the fence 20 that the vehicle gates are closed and the crossing signaling is on.

In this way, a barrier is connected to the entrance of the control unit of the crossing crossing the receiving and return routes of the autonomous and dispatch control stations, and the organization of movement through the crossing of rolling stock and autowatch transport is carried out by one operator — the duty officer on the move.
