Background

The need for a yard approach may place a switch, called a divergent switch, in the middle of the departure line. After the branch turnout is locked by the receiving/departure approach to the departure line, corresponding receiving/departure operation can be performed, and after the receiving/departure approach is used, the branch turnout needs to be unlocked, so that other operations of the departure line where the branch turnout is positioned are not affected, and the operation efficiency is improved.

When the split turnout is used by the vehicle receiving route, if the split turnout is not unlocked, normal handling of other vehicle receiving operations passing through the departure line can be affected, and driving efficiency is affected.

When the split turnout is used by the departure approach, if the split turnout is not unlocked, normal handling of other operations passing through the other position of the split turnout can be affected, and driving efficiency is affected.

When the train receiving route or the train departure route is not completely used, the train does not enter the departure line or does not go through the departure line for departure, if the split turnout is unlocked by mistake at the moment, the train can possibly be driven to a wrong direction, and even the train can directly rush out of the track, so that serious accidents are caused.

Because of the particularity of the positions of the split turnout, an effective means is needed to be provided for unlocking the split turnout after the locked of the connected road or the departure road, so that the split turnout is prevented from being unlocked erroneously when the connected road or the departure road is not used, and the split turnout can be unlocked in time after the use of the connected/departure road is finished, so that other connected/departure roads which are arrived at the departure road can be re-handled according to a specified plan.

In view of the defects of the split turnout unlocking method in the prior art, the unlocking method for the split turnout to the departure line is provided, and aims to ensure that the split turnout cannot be unlocked erroneously when the receiving route or the departure route is not used and is unlocked in time after the receiving/departure route is used, and ensure that other receiving/departure routes which reach the departure line can be re-handled according to a specified plan.

Referring to fig. 1, a technical scheme of an unlocking method for a split switch of a departure line according to the present embodiment is described, and the scheme is mainly divided into the following 3 stages:

first stage S1: an arrival line is arranged, two ends of the arrival line are provided with an outbound annunciator,

defining all train routes set by taking any one of the outbound annunciators as a terminal as train receiving routes,

and defining all train routes which are set by taking any one of the outbound annunciators as a starting end as departure routes.

The receiving routes are all receiving routes taking the outbound annunciator as a terminal. The departure routes are all departure routes taking the outbound annunciator as the starting end, and the train adopts any one of three modes to use the receiving route or the departure route.

mode two: departure from a departure route and completely past the beginning of the departure route according to the start signal indication of the departure route; entering an in-train side track section;

mode three: and canceling the set receiving route or the departure route.

Second stage S2: unlocking a section of the branching turnout of the receiving route or a section of the branching turnout of the departure route.

Third stage S3: after the train receiving route or the train departure route is used in any mode, if the branch turnout is still locked, the corresponding branch turnout is unlocked according to the train receiving route and the train departure route respectively.

In fig. 2, the approach to the departure train is all train approaches terminated by the departure signal for the approach. The departure routes are all train routes with the outbound annunciator as the starting end.

First, using the pick-up approach to the pick-up departure and the departure approach from the pick-up departure, referring specifically to fig. 2, 6G represents the main track section, S and XF represent the pick-up annunciators, S6 and X6 represent the pick-up annunciators, D22, D24, D26 and D30 represent the shunting annunciators, 50 and 52 represent the bifurcation switches, 46, 47 and 49 represent the switch points, DG represents the track section, 50DG represents the track section where bifurcation switch 50 is located, 52DG represents the track section where bifurcation switch 52 is located, and 48/50WG represents the no bifurcation section.

Setting a pickup access S-X6 to the main track section 6G of the departure track (the pickup access S-X6 to the departure track 6G includes a portion from the arrival signal S to the departure signal S6 in fig. 2), setting an departure access S6-XF to be departed by the bifurcated section 48/50WG of the departure track (the departure access S6-XF to be departed by the bifurcated section 48/50WG of the departure track includes a portion from the bifurcated section 48/50WG to the arrival signal XF in fig. 2): with specific reference to fig. 2, the track section 50DG where the branch switch 50 and the track section 52DG where the branch switch 52 are located of the receiving and sending route to the main track section 6G of the departure line are unlocked, and the section 50DG where the branch switch 50 and the track section 52DG where the branch switch 52 are located of the departure route S6-XF which is sent by the non-branch section 48/50WG of the departure line are unlocked. Finally, the split switches (50 and 52) are unlocked, and with specific reference to the split switch 50 and the split switch 52 in fig. 2, the track sections where the split switches (50 and 52) are located are respectively unlocked, the split switches (50 and 52) are unlocked, and the receiving/sending routes can be re-handled through the split switches (50 and 52).

After the train is processed in the receiving route, the train passes through the processed receiving route according to the receiving route indication and the position sequence of the branching turnout (50 and 52), crosses the terminal signal of the pressing connection vehicle route, completely crosses the terminal, enters the track section of the branching turnout or reaches the departure line, and the receiving route is used.

After the departure route is transacted, the train crosses the start signal of the pressure route according to the indication of the start signal and completely passes through the start of the route to enter the interior of the route, and the departure route is used.

After the receiving/sending route is processed, if the receiving/sending route is not needed for some reason, the processed route is canceled, and the receiving/sending route is considered to be used.

The train route is composed of a route start end, a route end, a track section and a turnout, for example, a part from an incoming signal S to an outgoing signal S6 shown in fig. 2.

With continued reference to fig. 2, the first stage S1 of the present embodiment will be described, in which the train uses the pickup route or the departure route in any one of the following three manners.

Mode T1: a pickup route S-X6 to the main track section 6G of the departure track is completed, and the train is set to pass through the pickup route in the order of the positions of the diverging switches in the pickup route and completely across the route terminal (the outbound annunciator X6 in fig. 2), occupy the non-bifurcated section 48/50WG, completely across the outbound annunciator X6, and enter the non-bifurcated section 48/50WG to the departure track.

Mode T2: an departure approach S6-XF for departure from the non-bifurcated section 48/50WG to the departure line is completed, and the train is set to occupy the main track section 6G, occupy the track section 49DG and enter the approach as indicated by the start signal from the outbound signal X6.

Mode T3: a pickup route S-X6 for picking up a pickup to the main track section 6G of the departure line is already handled, a route cancellation operation is set, and the pickup route S-X6 is cancelled; a departure route S6-XF from the non-bifurcated segment 48/50WG to the departure line is completed, a route cancellation operation is set, and the departure route S6-XF is cancelled.

Referring to fig. 2 and 3, a second stage S2 of the present embodiment is described, in which the section where the split switch is located is unlocked, including the steps of:

and using the train receiving access according to the mode T1, and unlocking the section of the split turnout of the train receiving access after the set condition is met.

After the vehicle is used to finish the vehicle-receiving route, on the basis of a mode T1:

step S21: the trains adopt a mode of orderly occupying clear zones where the split turnout is located:

con (condition) 1: in the topological connection relationship, the front track section (the non-branch section 48/50WG in FIG. 2) connected with the track section (e.g. the track section 50 DG) where the branch switch (the branch switch 50 in FIG. 2) is located is detected to be occupied first and then to be idle, and the track section 50DG where the branch switch 50 is located is detected to be occupied during the idle period.

con2: the track segment 50DG where the diverging switch is located is detected as idle.

con3: the occupation of the subsequent track section 52DG of the track section (50 DG) where the split switch (split switch 50 in fig. 2) is located is detected in the topological connection, and the process of detecting that the track section 50DG where the split switch (split switch 50 in fig. 2) is located is free after the pre-occupation occurs during the occupation.

When con1, con2 and con3 are satisfied simultaneously, the train passes through the section 50DG where the bifurcation switch 50 is located in a sequential occupancy clear manner.

Step S22: detecting unlocking time of a track section where the branching turnout of the receiving route S-X6 is located, and based on S21:

con4: the track section following the section 50DG where the bifurcation switch 50 is located is still the bifurcation switch 52 detected in the topological connection, and the track section 52DG is not unlocked.

con5: the detection of the track segment 50DG where the bifurcation switch is located is not due to a track outage.

con4& con5 is satisfied and the track section 50DG where the bifurcation switch 50 is located is unlocked.

The fact that the track is not caused by power failure refers to that each track section is associated with one track relay, whether the track section is occupied or unoccupied is judged by detecting the suction and dropping states of the track relay, when the track section is occupied by a train under normal conditions, the track relay drops, but when the track relay is powered off, the track relay also drops, and therefore the fact that the track relay drops due to power failure of the track relay is needed to be detected.

Step S23: steps S21 and S22 are cyclically executed until the section 52DG where the bifurcation switch 52 is located is unlocked.

As shown in fig. 2 and 4, the departure approach is used in the manner T2, and after a set condition is satisfied, the section of the departure approach where the branching switch is located is unlocked.

After the departure approach is completed, on the basis of a mode T2:

step S24: the train is pressed into the interior of the departure route:

con6: the start signal S6 (the start signal given by the outbound signal S6) that detects the train departure approach S6-XF is cross-pressed, i.e., it is detected that the outer track section 6G and the inner track section 49DG are occupied.

con6: the occupancy of the out-of-train track section 6G is detected.

con7: the occupancy of the in-train track section 49DG is detected.

con8: the train outer track section 6G is detected to be occupied first and then cleared.

According to the departure route direction, when a train can receive a route start signal sent by a start and stop signal machine on the departure route in a topological connection relation, a front section where the train is located is called as an out-of-train track section; according to the departure route direction, when the train can receive a route start signal sent by a start and stop signal machine on the departure route in a topological connection relation, a rear section positioned behind the train is called as the train inner track section.

Conditions con6, con7 and con8 are satisfied and the train has been pressed into departure route S6-XF Fang Ouduan DG (in-train track section 49 DG).

Step S25: the hairline is detected as idle.

The area to the hair line is defined as all the branch turnouts, the annunciators and the hair line which are connected with the hair line in a straight direction on a topological connection relation, the branch turnouts can be positioned in a direction and in a reverse direction, and the straight direction in all the branch turnouts connected with the hair line in the straight direction is the positioning position.

con9: the track sections 52dg,50dg where the split switches (split switches 50 and 52 in fig. 2) are located are idle for more than 3s by detecting that the hairline area is located to the hairline track sections (i.e., main track section 6G and no-switch section 48/50 WG) 6G and 48/50WG.

And if the con9 is met, the incoming line area is free.

Step 26: and detecting unlocking time of a track section where the branching turnout of the departure approach is located.

con10: the other departure route X6-S, which is opposite to the departure route S6-XF, is transacted without using the departure line 6G or 48/50WG.

con11: the occupancy of the rear section 47DG of the in-train track section is detected.

con12: the in-train track section 49DG is detected to be idle and the idle time exceeds 3s or more.

When con10, con11 and con12 are satisfied simultaneously, the sections 52dg,50dg of the split switch of the departure approach are unlocked.

And using the mode T3 to finish the receiving route or the departure route, and correspondingly unlocking the section where the branching turnout of the receiving route or the departure route is located after the set condition is met.

Aiming at the approach of the butt-joint vehicle:

step S27: the car-taking route S-X6 is normally canceled.

con13: and detecting that a cancellation command of the receiving vehicle access S-X6 is received.

con14: the front track section 46DG of the terminal X6, which detects the pickup path S-X6, is unlocked in a cancelling manner.

When con13 and con14 are simultaneously satisfied, the pickup route S-X6 is normally canceled.

S11: and detecting the start delay unlocking condition of the section where the bifurcation switch is located.

con15: and detecting that the departure area is not unlocked by the receiving vehicle route.

The fact that the departure area is not unlocked by the train receiving route means that after the train receiving route is detected to be canceled, the lock of the departure area is not released immediately, a forgiving time of 3s is needed, and the time for starting and delaying unlocking of the section where the bifurcation turnout is located is detected within the forgiving time range; after 3S, the departure area is unlocked by the pickup access S-X6.

con16: the track sections 52dg,50dg where the split switches are located are detected to be free from the hairline track section 6G (i.e., the main track section in fig. 2) and 48/50WG (i.e., the no-switch section in fig. 2).

con17: occupancy of any of the departure track sections 6G and 48/50WG, and the track sections 52DG and 50DG of the bifurcation switch is detected.

When con15 and con16 are simultaneously satisfied, the 3 second delay condition is satisfied by the start of the track segments 52dg,50dg where the bifurcation switches 52 and 50 are located.

Step S28: and detecting unlocking time of the track section where the branching turnout of the receiving route S-X6 is located.

con18: and detecting that the departure area is unlocked by the vehicle receiving route.

con19: it is detected that the 3s or 3min delay condition is satisfied and the delay time has arrived.

When con18 and con19 are simultaneously satisfied, the track sections 52dg,50dg of the diverging switches 52 and 50 of the pickup path are unlocked.

Step S29: detecting unlocking time of a track section where a branching turnout of a departure approach is located:

con20: and detecting that a cancel command of the departure route S6-XF is received.

con21: the rear track section 49DG on the departure approach initiation S56 topology connection relationship is detected to be unlocked.

con22: the departure approach start S6 is detected as not yet unlocked.

The unlocking of the starting end S6-XF of the departure route means that after a cancel command of the departure route S6-XF is detected, the locking of the departure route S6-XF is not released immediately, and after the rear track section 46G of the departure route S6-XF, which is in topological connection with the starting end, is required to be unlocked firstly, namely con14 is satisfied, and forgiving 250ms can unlock the starting end of the departure route.

When con20, con21 and con22 are satisfied simultaneously, the track sections 52dg,50dg of the departure routes at which the diverging switches 52 and 50 are located are unlocked.

Introducing the third stage of the embodiment, unlocking the bifurcation switch, specifically comprising the following steps:

after completion of the pickup path S-X6 to the departure line or the departure path S6-XF from the departure line, if the bifurcation switch (50 and 52 shown in fig. 2) is still locked, the other pickup paths will be affected, and therefore the bifurcation switch (50 and 52 shown in fig. 2) must be unlocked.

Step S31: unlocking the bifurcation switch (50 and 52 shown in fig. 2) for the junction car approach S-X6:

con23: the track sections 50dg,52dg of the split switches 50 and 52 are unlocked by the access way S-X6.

con24: the track sections 50dg,52dg where the diverging switches are checked are idle and the idle time exceeds 3s.

When con23 and con24 are satisfied simultaneously, the branch switch 50 and the branch switch 52 locked by the pickup path S-X6 are unlocked.

Step S32: for departure approach S6-XF, the bifurcation switches (50 and 52 shown in fig. 2) are unlocked:

con25: the track sections 50dg,52dg where the split switch 50 and the split switch 52 are located are unlocked by the departure approach S6-XF.

When con25 is satisfied, the switch 50 and the switch 52 locked by the departure path S6-XF are unlocked.

In summary, the present embodiment provides an unlocking method for a split switch to a departure line, wherein the split switch to the departure line is locked by a receiving/departure approach, and the split switch can be automatically unlocked after the receiving approach or departure approach is completed. The split turnout can not be unlocked by mistake when the receiving route or the departure route is not used, and can be unlocked in time after the receiving/departure route is used, so that other receiving routes or departure routes which are taken to the departure route can be ensured to be re-handled according to a specified plan. The train receiving route or the train departure route is not completely used, when the train does not enter the departure line or does not go through the departure line for departure, the split turnout is not unlocked by mistake, the turnout which is not unlocked can not be moved to another position, the train is prevented from being driven to the wrong direction or directly rushed out of the track, and serious accidents are avoided.
