Description

The invention relates to devices for signaling, centralization and blocking in railway transport, in particular to devices for interval regulation of train movement on the stages.

A device for automatic locking with a centralized placement of equipment containing rail circuits between the traffic lights that enclose the block sections. Generators and receivers for monitoring rail circuits are located at the electric centralization stations and are connected to the rails using cable lines. Blocks for controlling traffic lights with which they are connected by cable lines are located at a central point (see Dmitriev B.C., Minin V.A. Self-locking systems with tonal frequency rail circuits. - M.: Transport, 1992. P. 57).

The disadvantage of this device is the possibility of the appearance of permissive indications at the traffic lights in the case when the rail chain after occupying it by the train loses the shunt sensitivity (false freedom of the rail chain).

Closest to the claimed device is an automatic locking device with a centralized location of the equipment, comprising a rail circuit monitoring unit, including generators connected to the supply outputs with the beginning of the rail circuits, and receivers connected to the ends of the rail circuits, an alternating current source, a traffic light control unit, a lamp control unit red light of a traffic light, block circuit block of a block section, means of auxiliary opening, a signal block of a yellow light signal relay connected to the output by the first input the availability of the block section of the rail circuit control unit, and the second input to the open circuit output of the block section of the block circuit block (see Typical Design Materials. 410003 - TMP. Auto-lock with tone rail circuits and centralized placement of ABTC-2000 equipment. Album 3 . MPS GTSS, p. 8, p. 21, p. 26, p. 38-40).

The device provides closure of the block section, guarded by a traffic light when the train is being followed, and opens it with checking the execution of the sequence of releasing the rail chains and subject to the closure of the next block section in the direction of the train. In the event of malfunctions, an artificial opening is provided using the auxiliary opening means.

The disadvantages of the device, worsening the conditions for ensuring the safety of train traffic, are:

- if the sequence of release of the rail chains is violated due to external influences, for example, when servicing devices performed after the train passes, the block section will remain closed, and a prohibitory indication will remain at the traffic light enclosing it, which causes unjustified delays in the movement of trains;

- in the event of a dangerous failure in one of the block circuit blocks of the block section, when the block section is open, all subsequent block sections in the direction of the train will not be closed, which worsens the conditions for ensuring the safety of train traffic;

- in the event of a dangerous failure of the yellow light signal relay, the block section occupied by the train will not be fenced with a prohibitory indication of the traffic light, which directly affects the safety of train traffic;

- artificial blocking of the block section is carried out without checking the vacancy of the block section, which may lead to a violation of the safety of train traffic;

- it does not automatically restore the health of auto-lock after turning off and then turning on the DC source;

- the opening of the block section is carried out without a time delay, which should not be less than the possible duration of the loss of the shunt sensitivity of the rail circuit when moving a short movable unit, which worsens the conditions for ensuring the safety of train traffic;

- the opening of the block section occurs without checking that the next red block section includes red light, which worsens the conditions for ensuring the safety of train traffic.

The technical result of the invention is to increase the reliability of the automatic locking device with a centralized placement of equipment by monitoring the correct operation of units affecting traffic safety.

The technical result is achieved by the fact that an automatic locking device with centralized equipment placement, comprising a rail circuit monitoring unit, including generators connected by power outputs to the beginning of the rail circuits, and receivers connected to the ends of the rail circuits, an alternating current source, a traffic light control unit, a control unit traffic light red lamps, block circuit block, auxiliary opening means, yellow light signal relay block connected to the output by the first input according to the invention, it is equipped with a yellow fire signal monitoring unit for controlling the operation of the yellow relay signal relay connected to the free and busy outputs of the block section of the rail monitoring unit circuits, and the second inputs to the outputs of authorization and prohibition of the yellow light signal relay block, the key element connected to the control input to the output of the yellow light signal relay control unit, s the main input to the output of the AC source, and the output to the input of the traffic light control unit, the time delay unit, the signal generation unit for opening the block section, the start signal generation unit, the inverse signal generation unit, the power control unit, the input of which is connected to the open output block-section of the block circuit of the block-section, the output of the lack of power is connected to the first input of the start signal generation block, and the output of the presence of power is connected to the third input of the signal relay block the fire signal, the output of the resolution block of the signal relay of the yellow fire through the inverse signal generation unit is connected to the second input of the start signal generation unit, in which the third, fourth, fifth and sixth inputs are connected respectively to the output of the auxiliary opening means unit, to the closed-circuit output section of the circuit block block section, following in the direction of the train, the output of the control unit of the red light lamp of a traffic light, enclosing the next section of the section, and to the closed circuit output ka block circuit block of the block section, while the output of the block forming the trigger signal is connected to the first input of the block of the signal formation to open the block section, in which the second and third, fourth and fifth inputs are connected respectively to the outputs of free and busy block section of the rail monitoring unit circuits, to the output of the closure of the block section, the previous one in the direction of the train, the control unit of the rail circuits and to the output of the openness of the block section of the block block, the block-section, the previous one in the direction of the train, to generate a signal for opening the block section, it is connected through the time delay unit to the excitation input of the block section blocking circuit, the first and second inputs of this block are connected respectively to the permission output of the yellow light signal relay block of the traffic light enclosing the block section, and the resolution output of the signal block a yellow light relay of a traffic light that encloses the previous block section of a train.

As a result of the analysis of patent and scientific and technical information, no similar self-locking systems with centralized placement of equipment have been revealed, in which the correct operation of the units affecting traffic safety is ensured, which eliminates the inclusion of a permissive indication at the traffic light when the equipment is malfunctioning. This circumstance allows us to conclude about the novelty of the claimed invention, its compliance with the inventive step and the possibility of using it in modern self-locking systems.

The device operates as follows.

In the normal state, when the rail chains are free 5, 6, 7, 8, 9, 10, there are signals at the free outputs of the block sections, which are fenced by the traffic lights 1 and 2 of the block 11 for monitoring the rail chains. There are signals at the outputs of the openness of the block sections of blocks 15 and 16 of the circuit block closures, fenced by traffic lights 2 and 1. Blocks 16 and 17 of the circuit block sections, enclosed by the traffic lights 1 and 3, are connected similarly to block 15 circuit block block fenced by the traffic light 2 (not shown). There is a signal at the output of power control unit 27. There are signals at the resolution outputs of blocks 19 and 20 of the yellow fire signal relay of traffic lights 2 and 1. Block 20 is connected similarly to block 19 (not shown). Block 21 monitoring the operation of the yellow fire signal relay detects the coincidence of the signal values at the resolution output of block 19 and the free output of the block section, guarded by traffic light 2, block 11 for monitoring rail circuits, as a result of which a signal appears on the control input of key element 22 and a signal from source 12 of variable current enters the traffic light control unit 13, on which enabling light (not shown) is turned on. If the block 21 controlling the operation of the yellow light signal relay detects an unequal signal at the outputs of authorization and prohibition of block 19 and at the outputs of free and busy block section, guarded by traffic light 2, block 11 control rail circuits, the signal at the control input of the key element disappears, source 12 alternating current is turned off and the control unit 13 of the traffic light 2 turns on the traffic light prohibiting fire (not shown), which increases the safety of train traffic. There are no signals at the outputs of the signal generating unit 24 for opening the block portion and the trigger signal generating unit 25.

When the train enters the rail circuit 5 at the traffic light 1, the inhibitory light (not shown) is turned on, the signal disappears at the output of the resolution block 20 of the yellow fire signal relay of the traffic light 1 and, accordingly, at the second input of block 15. The block section protected by the traffic light 2 goes into mode pre-closure. When the train enters the rail circuit 7, the signal disappears at the free exit of the block section enclosed by the traffic light 2, the rail circuit control unit 11, and, accordingly, at the first input of the yellow light signal relay unit 19. As a result of this, the signals at the permission output of block 19 and at the first input of block 15 disappear. There is a preliminary closure of the block section enclosed by the traffic light 3 (not shown), and the final circuit of the block section enclosed by the traffic light 2, on which the prohibitory light is switched on (not shown) ) At the output of the isolation of the block portion of block 15, a signal appears.

A signal appears at the inhibit output of block 19, which, through the block 26 for generating the inverse signal of the yellow light signal relay of the traffic light 2, is supplied to the second input of the trigger signal generating block 25.

When the train enters the rail circuit 9, the block circuit is finally closed, guarded by the traffic light 3, on which the red light (not shown) is turned on. Signals appear at the output of the red light lamp control unit 14 and at the closure output of the block section of the block section 17 of the block section enclosed by the traffic light 3. These signals are applied to the inputs of the trigger signal generation block 25. At its output, a signal appears that verifies the fulfillment of the conditions: a block section is blocked by a traffic light 2, the next block section is blocked by a traffic light 3 and a red light is on, the yellow light signal relay block 19 gives an output signal prohibitions. The signal from the output of the block 25 of the formation of the starting signal is supplied to the first input of the block 24 of the formation of the signal to open the block section. After the appearance of the signal at the output of the freedom of the block section, shielded by the traffic light 2, block 11 monitoring the rail circuits, a signal appears at the second input of the block 24 of the formation of the signal to open the block section and, as a result, at its output. With a time delay, the value of which is controlled by the time delay unit 23, the signal from the output of the signal generation unit 24 to open the block section is fed to the excitation input of the block section 15 of the block section, which is protected by the traffic light 2. This block section opens. The device comes to its original state with the control of the correct operation of the blocks, affecting the safety of train traffic.

At the beginning of the maintenance of the devices at the moment when the train followed the traffic light 2 and the block section blocked by the traffic light 1 was opened, the track receivers of the rail circuits 6 and 7 may turn off additionally. In this case, the sequence of releasing the rail chains will be violated, however, due to the appearance of signals at the third, fourth and fifth inputs of the block 24 for generating a signal for opening the block section, a signal will appear at its output and after the release of block sections enclosed by traffic lights 2 and 1, roizoydet block opening portion of the partition 2. traffic light apparatus to the initial state with the control train safety conditions.

If the opening of the block section did not occur due to accidental malfunctions, then an artificial opening is required. It is performed using the auxiliary opening means 18, which acts on the third input of the trigger signal generating unit 25, which provides a signal at the output of the signal generating unit 24 to open the block section with checking the presence of signals at the inhibit output of the block 19 and at the output of the block section, fenced by traffic light 2, block 11 control rail chains, which increases the safety of train traffic.

When you turn off and then turn on the DC power, the block section may be closed. In this case, a signal appears on the lack of power output of the power control unit 27, as a result of which the block section is automatically opened, as well as when the auxiliary opening means 18 is exposed. After the block section is opened, the signal at the output of the presence of power is restored and disappears at the output of the lack of power of the power control unit 27. The device comes to its original state with the control of the correct operation of the blocks, affecting the safety of train traffic.

In the normal state, when the rail circuits 5, 6, 7, 8, 9, 10 are free, the relays 28 and 29 are activated in the control unit of the rail circuits 11 and the front contact 28.1 is closed. In blocks 15 and 16, relays 32 and 34 are excited, front contacts 33 and 35 are closed. In block 27 of the relay 63 is energized, its front contact 64 is closed. In blocks 19 and 20 of the yellow light signal relays of the traffic lights 2 and 3, relays 40 and 42 are energized, front contacts 41 and 43 are closed. In block 21, the same signals are sent to the inputs of the equivalence element 44 through the front contacts 28.1 of the relay 28 and 41 of the relay 40, as a result of which the signal 44 appears at the output of the element, which is fed through the OR element 46 to the control input of the key element 22, which opens and the signal from the source 12, the alternating current enters the traffic light control unit 13, on which enabling light (not shown) is turned on. If the signals at the input of element 44 are not equal, the signal at the output of element 44 will be absent and the key element 22 will be closed, the AC source 12 will be turned off and the traffic light control unit 13 will turn on the traffic light at the traffic light (not shown), which increases the safety of train traffic. In blocks 24 and 25 of the relay 50 of the formation of the signal to open the block section and 57 of the formation of the starting signal are turned off, contacts 51 and 58 are open.

When the train enters the rail circuit 5, the relay 42 turns off and a red light (not shown) is turned on at the traffic light 1. The contact 43 of the relay 42 is opened, as a result of which the block section, enclosed by the traffic light 2, enters the preliminary closure mode. When the train enters the rail circuit 7, the relay 28 in the control unit of the rail circuits 11 is turned off. Contact 28.1 opens, as a result of this, the yellow fire signal relay 40 of the traffic light 2 is turned off in block 19. When the front contact 41 of the relay 40 opens, the block section fenced traffic light 3 (not shown), and the final closure of the block section, fenced by traffic light 2, which turns on the prohibition light (not shown). In block 15, the relay 32 opens the front contact 33 and closes the rear. Through the rear contact, a signal is input to the input of element 53 And in block 25. When the armature of relay 40 in block 19 drops and the rear contact 41 closes, the armature in block 26 of relay 59 is attracted, relay 60 is turned on through contact 60 and its contact 62 is closed, through which a signal to the input of element 53 And in block 25. When the train enters the rail circuit 9, the block circuit is finally closed, guarded by the traffic light 3, on which the red light is turned on (not shown). In block 17, relay 36 is turned off, through its closed contact 37 a signal is supplied to the input of element 53 I. In block 14, the armature of relay 30 is attracted, which controls the burning of red light at traffic light 3. Through closed contact 30.1, a signal is input to the input of element 53 AND in block 25 . To all four inputs of element 53 And signals are received, as a result, relay 57 in block 25 is activated and closes its contact 58. In this case, the following conditions are checked: the block section is closed, guarded by traffic light 2, the block section next to the direction of the train is closed, enclosed traffic light 3 and the red light is on, the yellow light signal relay of the traffic light 2 is off and closes the rear contact.

Through the closed contact 58 of the relay 57, the signal is supplied to the signal generation unit 24 to open the block portion to the input of element 48 I. After releasing the block portion enclosed by the traffic light 2, which is detected by the actuation in the control unit of the rail circuits 11 of the relay 28 and the closure of its front contact 28.1, a signal is supplied to the second input of element 48 And, as a result, relay 50 is activated and closes contact 51. Through closed contacts 51 of relay 50 and 28.1 of relay 28, signals are received at the inputs of element 52 And, as a result, a signal appears that gives input to block 23, which is a standard device for monitoring the normalized value of the time interval (see, for example, 410003 - TMP, album 3, p. 51, MPS, GTSS). From the output of block 23, the signal through the OR element 31 is supplied to the relay 32 in the block 15 of the circuit block circuit, protected by the traffic light 2. Relay 32 attracts the armature. Through its closed contact 33, a signal is supplied to the input of element 39 AND in block 19. Other signals of the element 39 AND are supplied through closed contacts 28.1 of relay 28 of block 11 and 64 of relay 63 of block 27. As a result, relay 40 in block 19 attracts the armature, closes contact 41, and the block portion enclosed by the traffic light 2 is open. The device comes to its original state with the control of the correct operation of the blocks, affecting the safety of train traffic.

In case of violation of the sequence of releasing rail chains during maintenance work on the devices, when rail chains 6 and 7 are shunted after opening the block section enclosed by traffic light 1, the block section enclosed by traffic light 2 automatically opens after the rail chains 5, 6, 7 are released , 8. In this case, the actuation of the relay 50 of the formation of the signal for the opening of the block section in the block 24 occurs using the element 47 And, the inputs of which are fed through the closed contacts 35 of the relay 34, 29.1 relay 29 and closed th rear contact relay 28 28.1.

Artificial opening of the block section, fenced by traffic light 2, is carried out by pressing the button 38 in the tool 18, while the trigger signal generation relay 57 in the block 25 is excited through the elements 54 OR, 55 AND, 56 OR with the control that the signal relay of the yellow light of the traffic light 2 closes rear contact. Through a closed contact 58 of the relay 57, a signal is input to the input of the element 48 AND of the block 24. In the future, the block section is opened with its free control, which increases the safety of train traffic.

When you turn off and then turn on the DC power, the block section may be closed. In this case, the relay 63 releases the anchor and closes the rear contact 64, as a result of which the block section automatically opens. The operation algorithm of the circuit is the same as when the button 38 was pressed in the tool 18. After opening the block section enclosed by the traffic light 2, the relay 32 is activated, the relay 63 is activated through its closed front contact 33 and becomes self-locking via its own contact 63.1. The device comes to its original state with the control of the correct operation of the blocks, affecting the safety of train traffic.
