Firstly, referring to fig. 1, a technical solution of an unlocking method for a departure branch switch provided in this embodiment is described, which is mainly divided into the following 3 stages:

first stage S1: arranging a arrival line, wherein both ends of the arrival line are provided with an outbound signal machine,

defining all train routes which are set by taking any one outbound signal machine as a terminal as receiving routes,

and defining all train routes which are set by taking any one outbound signal machine as a starting end as departure routes.

The receiving approach is all the receiving approaches taking the outbound signal machine as the terminal. The departure approach is all departure approaches with an outbound signal machine as a starting end, and the train uses the receiving approach or the departure approach in any one of three ways.

the second method comprises the following steps: according to the starting end signal indication of the departure route, departure is carried out from the departure line, and the departure route completely passes through the starting end of the departure route; entering a square track section in the train;

the third method comprises the following steps: and canceling the set route for receiving the vehicle or the route for departure.

A second stage S2: and unlocking the section where the divergent turnout of the receiving route is located or the section where the divergent turnout of the departure route is located.

Third stage S3: after the receiving approach or the departure approach is used in any one of the manners, if the divergence turnout is still locked, the corresponding divergence turnout is unlocked according to the receiving approach and the departure approach respectively.

In fig. 2, the arrival route is a route for receiving the arrival of the train from the departure terminal, and the arrival route is all the train routes terminated by the outbound traffic signal. The departure route is all the train routes with the outbound signal machine as the starting end.

First, using the pickup route to the departure route and the departure route from the departure route, specifically referring to fig. 2, 6G denotes a main track section, S and XF denote inbound signals, S6 and X6 denote outbound signals, D22, D24, D26, and D30 denote turn signals, 50 and 52 denote diverging switches, 46, 47, and 49 denote switches, DG denotes a track section, 50DG denotes a track section where the diverging switch 50 is located, 52DG denotes a track section where the diverging switch 52 is located, and 48/50WG denotes a turnout section.

A pick-up route S-X6 to the main track section 6G of the departure line is set (the pick-up route S-X6 to the departure line 6G includes a portion from the inbound signal S to the outbound signal S6 in fig. 2), and a departure route S6-XF to the departure line 48/50WG is set (the departure route S6-XF to the departure line 48/50WG includes a portion from the turnout section 48/50WG to the inbound signal XF in fig. 2): the receiving route and the departure route are set to be used, specifically referring to fig. 2, the track section 50DG where the divergent switch 50 of the receiving route to the main track section 6G of the departure line is located and the track section 52DG where the divergent switch 52 is located are unlocked, and the track section 50DG where the divergent switch 50 of the departure route S6-XF of the departure line 48/50WG of the departure line is located and the track section 52DG where the divergent switch 52 is located are unlocked. Finally, the divergence switches (50 and 52) are unlocked, specifically with reference to divergence switch 50 and divergence switch 52 in fig. 2, the track section in which the divergence switches (50 and 52) are located is unlocked, the divergence switches (50 and 52) are unlocked, and the pick-up/departure approach can be re-handled through the divergence switches (50 and 52).

After the receiving route is handled, the train crosses the terminal signal of the crimping car route according to the receiving route indication and the position sequence of the bifurcation switches (50 and 52) according to the handled receiving route, and completely crosses the terminal to enter the track section where the bifurcation switches are located or to the departure line, so that the receiving route is used.

After the departure route is handled, the train crosses the start signal of the pressure route according to the indication of the start signal, completely crosses the start of the route and enters the inside of the route, and then the departure route is used.

After the transaction of the route for receiving/dispatching the train, if the train is not needed for some reason, the transaction route is cancelled, and the use of the route for receiving/dispatching the train is considered to be finished.

The train route is composed of a route start end, a route end, a track section, and a switch, for example, a portion from an inbound signal S to an outbound signal S6 shown in fig. 2.

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

Mode T1: a receiving route S-X6 to the main track section 6G of the departure line is already processed, and the trains are arranged to pass through the receiving route and completely cross the route terminal (the outbound signal X6 in fig. 2) according to the position sequence of the branch switch in the receiving route, occupy the turnout section 48/50WG, completely cross the outbound signal X6, and enter the turnout section 48/50WG on the departure line.

Mode T2: an outbound route S6-XF for outbound from the turnout zone 48/50WG of the outbound line is processed, and the train is set to occupy the main track zone 6G and the track zone 49DG according to the indication of the start signal sent by the outbound signal machine X6 and enter the route.

Mode T3: a receiving route S-X6 for receiving vehicles to the main track section 6G of the arrival and departure line is managed, route canceling operation is set, and the receiving route S-X6 is canceled; an outbound route S6-XF from the trouble-free section 48/50WG of the inbound route is completed, and an outbound route cancellation operation is set, and the outbound route S6-XF is cancelled.

With reference to fig. 2 and fig. 3, the second stage S2 of the present embodiment is described, and the unlocking of the section where the divergent switch is located includes the following steps:

and using the receiving approach according to the mode T1, and unlocking the section of the bifurcation turnout of the receiving approach after set conditions are met.

After the vehicle receiving approach is completed, on the basis of the mode T1:

step S21: the train passes through the section of the branch turnout in a sequential occupation and clearance mode:

con (condition) 1: it is detected that in the topological connection relationship, the front track section (the turnout section 48/50WG in FIG. 2) connected to the track section (for example, the track section 50 DG) where the divergent turnout (the divergent turnout 50 in FIG. 2) is located is occupied first and then idle, and during the idle period, the track section 50DG where the divergent turnout 50 is located is detected to be occupied.

con2: the track section 50DG where the diverging switch is located is detected as free.

con3: detecting that the track section 52DG located at the track section (50 DG) of the divergent turnout (50 DG in figure 2) is occupied at the topological connection relation, and detecting that the track section 50DG located at the divergent turnout (50 in figure 2) has a process of pre-occupation and then idling during the occupation.

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

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

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

con5: the track section 50DG in which the divergent switch is located is detected to be occupied not because of a power outage in the track.

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

The track relay is not caused by track power failure, namely, each track section is associated with one track relay, whether the track section is occupied or idle is judged by detecting the suction and falling states of the track relays, and when a train occupies the track section under normal conditions, the track relays can fall down, but when the track relays have power failure, the track relays also can fall down, so that the track relays which are not caused by the power failure of the track relays need to be detected.

Step S23: step S21 and step S22 are executed in a loop until the section 52DG where the divergence switch 52 is located is unlocked.

As shown in fig. 2 and 4, the departure route is used according to the method T2, and after the set condition is satisfied, the section where the divergence switch of the departure route is located is unlocked.

After the departure route is finished, on the basis of the mode T2:

step S24: pressing the train into the inner side of the departure route:

con6: the start signal S6 (start signal given by the outbound signal S6) that detects the departure route S6-XF of the train is cross-compressed, that is, the occupation of the outer track section 6G and the inner track section 49DG is detected.

con6: and detecting the occupation of the track section 6G outside the train.

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

con8: and 6G, detecting the occupation of the track section outside the train and then clearing.

According to the departure route direction, when a train can receive a route starting end signal sent by a starting end outbound signal machine on the departure route in a topological connection relation, a front section where the train is located is called an outer-train track section; according to the departure approach direction, in the topological connection relation, when a train can receive an approach starting end signal sent by a starting end outbound signal machine on the departure approach, a rear section behind the train is called as the track section inside the train.

The conditions con6, con7, and con8 are satisfied, and the train has been pushed into the departure route S6-XF inside section 49DG (inside-train track section 49 DG).

Step S25: it is detected that the outgoing thread is free.

The method is characterized in that a departure line area is defined as all branch switches, signal machines and departure lines which are connected with the departure line in the straight direction on a topological connection relationship, the branch switches can be opened to two positions of positioning and reverse positioning, and the straight direction in all the branch switches connected with the departure line in the straight direction is the positioning position.

con9: it is detected that the originating track section (i.e., main track section 6G and turnout-free section 48/50 WG) 6G and 48/50WG to which the originating zone is located is free, the track sections 52DG,50DG to which the diverging switches (diverging switches 50 and 52 in FIG. 2) are located are free, and the free time exceeds 3s or more.

And if the con9 is satisfied, the outgoing line area is free.

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

con10: the

departure line

6G or 48/50WG is not used to transact another departure leg X6-S as opposed to the departure leg S6-XF.

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

con12: the inside-train track section 49DG is detected to be free for more than 3 seconds.

When con10, con11 and con12 are satisfied simultaneously, the section 52dg,50dg where the divergent switch of the departure route is located is unlocked.

And completing the receiving approach or the departure approach according to the mode T3, and correspondingly unlocking the section where the divergent turnout of the receiving approach or the departure approach is located after the set conditions are met.

Aiming at the approach of receiving the train:

step S27: and the receiving route S-X6 is normally cancelled.

con13: the reception of a cancel command for the pickup route S-X6 is detected.

con14: the front track section 46DG of the terminal X6 that detects the pick-up route S-X6 is unlocked in a cancellation manner.

And if con13 and con14 are satisfied simultaneously, the receiving route S-X6 is normally cancelled.

S11: and detecting the starting delay unlocking condition of the section where the divergent turnout is located.

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

The arrival route area is not unlocked by the pickup approach, which means that the locking of the arrival route area cannot be immediately released after the pickup approach is detected to be cancelled, the promptness time of 3s is needed, and the starting delay unlocking time of the section where the divergent turnout is located is detected within the promptness time range; and 3S later, unlocking the receiving route S-X6 only when the line-sending area is reached.

con16: it is detected that the outgoing line zone is located in the outgoing line track section 6G (i.e. the main track section in FIG. 2) and 48/50WG (i.e. the turnout section in FIG. 2) free, and the track sections 52DG,50DG where the divergent turnout is located are free.

con17: the occupation of any one of the outgoing

line track sections

6G and 48/50WG where the outgoing line area is located and the track sections 52DG and 50DG where the divergent switch points are located is detected.

When con15 and con16 are satisfied simultaneously, the 3-second delay condition is satisfied when the track sections 52DG and 50DG where the diverging switches 52 and 50 are located are started.

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

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

con19: and detecting that the 3s or 3min delay condition is met, and the delay time is up.

con21: the unlocking of the rear track section 49DG on the topological connection relationship at the departure route start S56 is detected.

con22: and detecting that the departure starting end S6 is not unlocked.

The unlocking of the departure route starting end S6-XF means that after detecting that the departure route S6-XF cancels the command, the locking of the departure route S6-XF is not immediately released, and after the rear track section 46G in the departure route S6-XF in the topological connection relationship with the starting end needs to be unlocked first, that is, the con14 is satisfied, and the departure route starting end is unlocked only after 250ms is forgiveness.

When con20, con21 and con22 are satisfied simultaneously, the track sections 52dg,50dg in which the diverging points 52 and 50 of the departure route are located are unlocked.

Introducing the third stage of this embodiment, unlocking a divergent switch, specifically includes the following steps:

after completing the pick-up route S-X6 to the departure route or the departure route S6-XF from the departure route to the departure route, if the diverging switches (50 and 52 shown in fig. 2) are still locked, the other pick-up routes will be affected, and therefore the diverging switches (50 and 52 shown in fig. 2) must be unlocked.

Step S31: for pick-up approach S-X6, the divergence switch (50 and 52 shown in fig. 2) is unlocked:

When con23 and con24 are satisfied at the same time, divergence switch 50 and divergence switch 52 locked by the vehicle-receiving route S-X6 are unlocked.

Step S32: for departure legs S6-XF, the divergence switch (50 and 52 shown in FIG. 2) is unlocked:

con25: the track sections 50DG,52DG in which the diverging switch 50 and the diverging switch 52 are located are unlocked by departure lanes S6-XF.

When con25 is satisfied, the divergence points 50 and 52 locked by the departure route S6-XF are unlocked.

In summary, the present embodiment provides an unlocking method for a branch switch to an departure line, in which the branch switch to the departure line is locked by a departure/arrival route, and the branch switch can be automatically unlocked after the departure/arrival route is used.
