Description

Switch control method and device

Technical Field

The invention relates to the technical field of rail traffic control, in particular to a turnout control method and a turnout control device.

Background

The mainstream signal system in the market is CBTC (Communication Based Train Control System, communication-based train automatic control system) system based on train-ground communication. In conventional CBTC systems, the interlock subsystem is responsible for control of trackside equipment (e.g., switches, etc.). The interlocking subsystem takes the front fork direction, the rear fork direction and the rear fork side direction of the turnout as a logic section. The switch and the route can be unlocked only when the train completely leaves the logic section where the switch is located, and the rear train can enter the switch according to the re-handled route. When the front car and the rear car respectively pass through the straight direction or the side direction of the turnout, the processing method delays the time for moving the turnout, consumes more time for handling the route, and limits the time for the rear car to pass through the turnout. In the CBTC system, the rear vehicle can enter the turnout area only after waiting for the front vehicle to completely go out of the logic section, and the running of the rear vehicle is limited.

With the development of urban rail transit technology, the operation pressure is increased, and higher requirements are put on a signal system. On the premise of ensuring the running safety of the trains, how to reduce the running interval between the trains and improve the running capability is a technical problem to be solved in the field.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The method and apparatus for switch control provided by the present invention are described below with reference to fig. 1-8.

Fig. 1 is a schematic flow chart of a method for controlling a switch according to the present invention, as shown in fig. 1, the method for controlling a switch is applied to ATP of a train, and includes:

step 101, determining a first logic section where a turnout is located and an overrun area;

Step 102, calculating the boundary for triggering the switch solicitation request and the boundary for triggering the overrun region solicitation request based on the first logic section and the overrun region respectively, and sending the corresponding solicitation request to the LCS when meeting the condition of sending the solicitation request and/or the overrun region solicitation request of the switch;

and step 103, determining the type of soliciting the turnout and the type of soliciting the overrun region according to feedback information of LCS.

Specifically, the ATP (Automatic Train Protection, train automatic protection subsystem) on the train determines a first logical zone in which the switch is located, and the range of the first logical zone includes the movable zone of the switch.

Determining a boundary triggering a switch solicitation request positioned in the first logic section according to the first logic section and a corresponding algorithm; in order to realize that the running speed of the train is not reduced, before the running direction of the train does not reach the first logic section corresponding to the turnout, a neighboring point, namely the solicited boundary of the turnout, is determined on the track in advance. When the train operation reaches the switch solicitation boundary, the ATP is triggered to send a switch solicitation request to the LCS (line control system, train control system). The train is ensured to have corresponding idle track resources to be provided for the train in the existing running direction, and the speed of the train is kept unchanged. And the train sequentially reaches the adjacent boundary points of the turnout during running, and the intersection point of the first logic section and the track.

Similarly, determining the boundary of the request for triggering the overrun region according to the range of the overrun region; in order to prevent the speed of the train from decreasing, a neighboring point, namely the solicitation boundary of the overrun region, is determined on the track in advance before the train reaches the overrun region in the running direction of the train. When the train operation reaches the boundary of the overrun area, the ATP is triggered to send the overrun area solicitation request to the LCS. And according to the running direction of the train, the adjacent point of the overrun region is reached, and then the intersection point of the overrun region and the track is reached.

The solicited boundary of the overrun area and the solicited boundary of the turnout are determined according to a corresponding algorithm, and in the running direction of the train, the solicited boundary of the overrun area or the solicited boundary of the turnout is not necessarily passed, and the determination of the adjacent boundary point is related to factors such as the running speed of the train, the limit, the communication time delay and the like.

After determining the boundary for triggering the switch solicitation request and the boundary for triggering the overrun region solicitation request, it is necessary to further determine whether the condition for sending the switch solicitation request and/or the overrun region solicitation request is satisfied.

If the condition of sending the turnout solicitation request is met, the condition that the current turnout resource can be solicited by the train is indicated, when the train reaches the solicitation boundary, the corresponding solicitation request is needed to be sent to the LCS, the LCS system feeds back information to the ATP of the train according to the running state of the current rail train, so that whether the current rail can be solicited and the solicitation type, such as exclusive solicitation or shared solicitation, are judged.

The invention provides a turnout control method, which is characterized in that a locking mechanism is respectively applied to a track section, a turnout, an overrun area and the like. When the train goes out of the movable area of the turnout, the current train can release the application of the turnout, and the rear train can add a lock for the turnout to apply the turnout. By means of the train control system based on train-to-train communication, the time for moving the turnout is shortened, the running interval between trains is shortened, the running efficiency of the trains is improved, and the running pressure is reduced.

Specifically, in order to realize the fine management of LCS on the switch, the dividing principle of the conventional CBTC system on the track section where the switch is located is modified, as shown in fig. 2, and the specific dividing principle is as follows:

Dividing the turnout section into 4 logic sections according to the turnout movable region turnout front boundary, the turnout movable region turnout rear straight boundary and the turnout movable region turnout rear side boundary.

According to the straight after-fork side direction warning mark and the side after-fork side direction warning mark and the fork point, dividing the side-switch side-impact protection area into the straight after-fork side-impact protection area and the side after-fork side-impact protection area.

And dividing the overrun section into a straight overrun region behind the fork according to the warning mark position, and laterally overrun region behind the fork.

The specific method for determining the overrun region comprises the following steps: the position of the warning mark is vertical to the straight behind the fork and is provided with an intersection point, and the warning mark is the straight behind the fork; taking a broken line elliptical region between a turnout point and a straight-direction warning mark after turnout as a straight-direction overrun region after turnout, and recording as an overrun region A; the fork point is the intersection point of the straight track and the lateral track.

Similarly, the position of the warning mark is perpendicular to the rear side direction of the turnout and is provided with an intersection point which is the rear side warning mark of the turnout, and a broken line oval area between the turnout tip and the rear side warning mark of the turnout is taken as a rear side overrun area of the turnout and is marked as an overrun area B.

There are two directions of travel for the train: straight running and sideways running. When the train runs in the straight direction or in the lateral direction, track resources in the running direction of the train are subdivided, corresponding sections are acquired in a sectionalized mode, the time for the train to handle the route is shortened, the time for the train to occupy the corresponding track area is shortened, the running interval of the train is shortened, and the running efficiency is improved.

Specifically, the ATP of the train takes the point of a first logic section where the turnout is located, which is closest to the train head, as a first boundary point, takes the first boundary point as a starting point for calculating the turnout solicited boundary, and determines a first solicited boundary corresponding to the train in the reverse running direction according to a solicited boundary algorithm;

Meanwhile, the ATP of the train takes the point closest to the train head in the overrun area as a second boundary point, and takes the second boundary point as a starting point for calculating the solicited boundary of the overrun area, and the second solicited boundary corresponding to the train in the reverse running direction is determined according to a solicited boundary algorithm.

Therefore, the train is enabled to trigger the corresponding solicited boundary request preferentially according to which solicited boundary is reached first in the running direction.

Specifically, after determining the solicited boundary (i.e., the first solicited boundary) of the switch and the solicited boundary (i.e., the second solicited boundary) of the overrun region, the train continues to travel along the original route, and may pass through the first solicited boundary and the second solicited boundary according to the traveling direction.

Preferentially, which solicitation boundary is passed, whether the condition for sending the corresponding solicitation request is satisfied is firstly judged, for example: the first solicitation boundary is reached first, whether the train meets the condition of the switch solicitation request is judged preferentially, and if the condition of the switch solicitation request is met, the switch solicitation request is sent to the LCS. And when the second solicitation boundary is reached, judging whether the train meets the condition of the solicitation request of the overrun region, and sending the solicitation request of the overrun region to the LCS system under the condition of meeting the condition.

In contrast, if the second solicitation boundary is reached first and then the first solicitation boundary is reached, the corresponding determination method is as described above, but the order is reversed.

In particular, all the running routes of the trains are known, so that the switch on each route should have its corresponding direction of departure within a preset time so that the trains run according to the established track.

In actual running, after the train reaches the first solicited boundary, triggering a corresponding turnout solicitation request, and judging whether the corresponding condition is met.

First, a safety envelope of a train is determined, and as shown in fig. 3, a safety position of the train is generally obtained by adding a train safety envelope with an error distance to an estimated position (which is a safety position) of the train obtained by a high-precision positioning method. The safety envelope is a distance added at an unsafe location to ensure the safety of the train location. The train safety envelope in fig. 3 is the current possible position of the train considered by the system after the position error of the head and the tail of the train is considered. As shown in fig. 3, the train safety envelope is composed of four points including a maximum safety front end, a minimum safety front end, a maximum safety rear end, and a minimum safety rear end. The maximum safe rear end is calculated by subtracting the length of the train from the position of the maximum safe front end, and the minimum safe rear end is calculated by subtracting the length of the train from the position of the minimum safe front end.

In the invention, the safety envelope of the train is mainly determined by the maximum safety front end and the minimum safety rear end.

In the direction of travel of the train, the safety envelope of the train reaches or has passed the first solicitation boundary, i.e. the maximum safety front of the train reaches the first solicitation boundary or the maximum safety front of the train has passed the first solicitation boundary, and the switch is not solicited exclusively by other trains.

And determining the current opening direction of the turnout, comparing the current opening direction and the expected opening direction of the turnout, and when the train confirms that the current opening direction of the turnout is consistent with the expected opening direction, applying a sharing solicitation request to the LCS by the train without applying for moving the turnout. When the train confirms that the current opening direction of the turnout is inconsistent with the expected opening direction, the train needs to send an exclusive solicitation request of the turnout to the LCS, and apply for moving the turnout to the expected position to the LCS.

Specifically, in the running direction of the train, it is determined that the safety envelope of the train reaches or has passed the second solicitation boundary, that is, the maximum safety front end of the train reaches the second solicitation boundary or the maximum safety front end of the train has passed the second solicitation boundary, and the target overrun region is not solicited exclusively by other trains. For a certain switch, the overrun region comprises a straight overrun region behind the switch and a lateral overrun region behind the switch. The fork rear direct overrun region refers to a region from the fork tip to the straight strand corresponding to the warning mark position, and the fork rear lateral overrun region refers to a region from the fork tip to the side strand corresponding to the warning mark position. The specific determination method comprises the following steps: the position of the warning mark is perpendicular to the intersection point of the straight direction behind the fork, and is the straight direction warning mark behind the fork; taking a broken line elliptical region between a turnout point and a straight-direction warning mark after turnout as a straight-direction overrun region after turnout, and recording as an overrun region A;

similarly, the position of the warning mark is perpendicular to the intersection point of the side direction behind the turnout, the warning mark is the side warning mark behind the turnout, a broken line elliptical region between the turnout tip and the side warning mark behind the turnout is taken as a side overrun region behind the turnout, and the broken line elliptical region is marked as an overrun region B.

The train receives an ATS operation plan, whether the original running route of the train needs to be turned back or not is judged according to the ATS operation plan, if so, the train needs to inquire an overrun area A and an overrun area B, and the train ATP sends an exclusive overtaking request of the overrun area to the LCS;

if no turn-back is needed, the train is only required to solicit the overrun area A or overrun area B, and the train ATP sends a sharing solicitation request of the overrun area to the LCS.

When the LCS receives the request for requesting the overrun area on one side of the switch sent by the ATP, it needs to combine the requesting situation of the overrun area on the other side of the switch to determine whether the overrun area on the other side can be requested.

When the overrun area A is judged to be exclusively used by the train, the overrun area B needs to be determined to be not used by the train, and the overrun area A is not used by other trains.

When the overrun area A is judged to be shared by the train, the overrun area B is required to be determined to be not shared by the train, and the overrun area A is not shared by the train or the overrun area A is shared by other trains or the overrun area A is only shared by the train.

Here, being recruited by a train includes being recruited by the own train and other trains, and the recruitment types include: exclusive or shared solicitation.

Optionally, the method further comprises:

Specifically, along with the shape of the train, after the train judges that the turnout and the overrun area are not needed any more, the application of releasing the assessed resources can be carried out. Besides the turning-back scene of the train, under other conditions, when the train safety envelope is out of the movable area of the turnout, the turnout can be applied to release the turnout. Except for the scene of turning back the train, under other conditions, when the train safety envelope is out of the clear overrun region, the overrun region can be applied to be released.

Aiming at the scene of turning back the train, when the train is turned out, the train safety envelope is wrapped out of the movable area of the turnout to apply for releasing the turnout.

Aiming at a train turning-back scene, when the train is turned out, the train safety envelope is clear of the overrun area A, and the overrun area A can be applied to be released; when the train is folded out, the safety envelope is covered out of the clear overrun area B, and the release overrun area B can be applied.

The invention provides a turnout control method and a turnout control device, which are characterized in that locking mechanisms are respectively applied to a track section, a turnout, an overrun area and the like. When the train goes out of the movable area of the turnout, the current train can release the application of the turnout, and the rear train can add a lock for the turnout to apply the turnout. By means of the train control system based on train-to-train communication, the time for moving the turnout is shortened, the running interval between trains is shortened, the running efficiency of the trains is improved, and the running pressure is reduced.

Fig. 4 is a second flow chart of a method for controlling a switch according to the present invention, as shown in fig. 4, the method is applied to a train control system, and includes:

step 401, receiving a solicitation request sent by train ATP;

step 402, determining whether the solicitation request is a corresponding turnout or an overrun area in the first logic section, and sending feedback information according to the solicitation conditions of the turnout and the overrun area, so that the train can determine the solicitation type of the turnout and the solicitation type of the overrun area according to the feedback information;

Specifically, the area of the track where the turnout is located is finely divided, the boundary point is defined by the front boundary of the turnout movable area switch, the straight boundary behind the turnout movable area switch and the three points of the side boundary behind the turnout movable area switch, and the area of the track where the turnout is located is divided into four logic sections. The first logic section is a region defined by three points, namely a front boundary of a turnout movable region turnout, a rear straight boundary of the turnout movable region turnout and a rear lateral boundary of the turnout movable region turnout.

The LCS of the train control system receives the solicitation request sent by the train ATP, and the solicitation types may be two kinds, exclusive solicitation and shared solicitation.

It is determined whether the solicitation request sent by the ATP is a solicitation request for a switch located in the first logical zone or a solicitation request for an overrun zone.

If the request is a request for evaluating the turnout in the first logic section, the LCS system determines whether the turnout is evaluated exclusively or is evaluated in a sharing manner in a corresponding period, or no train is evaluated, and sends feedback information to the ATP of the train, and the ATP of the train determines the type of evaluating the turnout according to the feedback information, and the turnout is evaluated exclusively or is evaluated in a sharing manner.

If the request is a request for requesting the overrun area, the LCS system determines whether the condition of requesting the overrun area is exclusive or shared or no train is requested, and sends feedback information to the ATP of the train, and the ATP of the train determines the type of requesting the overrun area according to the feedback information.

Specifically, if it is determined that the solicitation request is a solicitation request for a switch located in the first logical section, it is necessary to determine whether the solicitation type is an exclusive solicitation or a shared solicitation.

The ATP of the train determines the solicitation condition of the turnout according to the current opening direction and the expected opening direction of the turnout in the running direction, wherein the expected opening direction is the opening direction corresponding to the turnout of the train according to the original running route in the running plan.

If the solicitation request is determined to be a corresponding overrun region, judging whether the solicitation type is exclusive solicitation or shared solicitation is needed.

The judgment mode is to determine whether to send feedback information of successful solicitation by soliciting the solicitation of the overrun region on the corresponding side of the overrun region and whether the solicitation of the overrun region on the other side meets the preset condition of the overrun solicitation.

Firstly judging the type of the solicitation request, then matching the corresponding solicitation conditions according to the type of the solicitation request, judging whether the corresponding solicitation conditions are met, if so, giving successful feedback information to the solicitation, and enabling the train ATP to run without decelerating according to the running plan after receiving the corresponding feedback information. If not, feedback information is given to solicitation failure. After receiving the corresponding feedback information, the ATP of the train continuously sends the solicitation request, and if the successful solicitation feedback information is not received within a certain range, the train can be stopped.

Specifically, when the LCS receives a switch solicitation request sent by the train ATP, it first determines whether the solicitation request is an exclusive solicitation or a shared solicitation;

the LCS system determines whether the situation of the turnout is exclusive or shared or no train is required, sends feedback information to the ATP of the train, and determines the type of the turnout required according to the feedback information. Such as: the LCS feedback information indicates that the track is exclusively solicited in the corresponding period, and after the train ATP receives the information, it is known that the track has no available resource and can continuously send a solicitation request to the LCS system.

When the LCS feedback information indicates that the track is shared and solicited in the corresponding period, the train ATP receives the information and then knows that the track has available resources, but the track resources need to be shared with other trains, and the shared and solicited request corresponding to the train ATP can successfully obtain the track resources.

When the LCS feedback information indicates that the track is train-empty in the corresponding period, the request for exclusive solicitation and the request for shared solicitation of ATP of the train can successfully obtain the track resource.

Specifically, the LCS receives the request for requesting the super-zone area, determines whether the request is exclusive or shared, then matches the corresponding request condition, determines whether the corresponding request condition is satisfied, and sends feedback information of successful request to the ATP of the train if the request is satisfied. If the information is not satisfied, feedback information indicating failure is sent to the train ATP.

If the request is an exclusive solicitation, the LCS system may determine whether the current solicitation of the overrun region a is already solicited by the train exclusively, or whether the request is a request for an exclusive solicitation of the overrun region a, or whether the request is a shared solicitation, or whether the request is not solicited. If the train is already exclusively or shared, the information fed back to the train ATP indicates that the request fails.

If the over-limit area B is not recruited by the train, determining whether the over-limit area B is not recruited by the train, and if the over-limit area B is not recruited by the train, acquiring feedback information of successful request by the exclusive solicitation request of the over-limit area.

Similarly, if the overrun region solicitation request is an exclusive solicitation request of the overrun region B, the same method is used for respectively judging whether the overrun region B and the overrun region A are not solicited, if the overrun region B and the overrun region A are not solicited, the exclusive solicitation request of the overrun region can be successful only if the overrun region B and the overrun region A are not solicited, otherwise, the train ATP always sends the exclusive solicitation request of the overrun region, and in a certain range, the train is controlled to stop under the condition that successful feedback information is not received yet.

If the request is a sharing request, the LCS system determines whether the current request of the overrun area a is requested by the exclusive request of the train, or the sharing request is requested by the overrun area a, or not. If the shared request is not acquired by the train or is acquired by other trains or is acquired by the own train, and then determining that the adjacent overrun region is not acquired by the train, the shared acquisition request of the overrun region obtains feedback information of successful request.

Optionally, the method further comprises:

Specifically, the LCS system responds to the switch solicitation request preferentially in the actual operation process, judges the solicitation request type and the corresponding condition, and sends feedback information of successful or failed solicitation to the train ATP.
