Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A train route automatic triggering method, apparatus, system, train and target controller according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a train route auto-triggering method according to an embodiment of the present invention. It should be noted that the train route automatic triggering method of the embodiment of the present invention can be applied to trains.

As shown in fig. 1, the train route automatic triggering method may include:

and S110, acquiring the current position information of the train.

Optionally, the train can obtain the position information of the train in real time through a positioning module of the train; alternatively, the train may periodically acquire the location information of the train at regular intervals. The time interval for acquiring the train position may be related to the running speed of the train, for example, the faster the running speed of the train, the shorter the time interval, and the slower the running speed of the train, the longer the time interval.

And S120, judging whether the front of the train is a turnout area or not according to the current position information and the vehicle-mounted electronic map. In the embodiment of the present invention, the switch area refers to a track area including one or more switches.

Optionally, after obtaining the current position information of the train, the current position information may be matched with the position coordinates in the vehicle-mounted electronic map to determine whether the front of the train is a turnout area on the track line. In the embodiment of the present invention, the vehicle-mounted electronic map may be pre-established, and if the contents contained in the vehicle-mounted electronic map are different, the manner of determining whether the front of the train is a turnout area according to the vehicle-mounted electronic map will also be different, and two different examples will be given below:

as an example of one possible implementation, the onboard electronic map may include position coordinates of points on the track line (where the position coordinates may be understood as geographical position coordinates). In this example, the specific implementation process of determining whether the front of the train is the turnout zone according to the current position information and the vehicle-mounted electronic map may be as follows: and judging whether the train runs to a target point currently according to the current position information and the position coordinates of each point on the track line in the vehicle-mounted electronic map, wherein the target point is used for indicating a point which is a first threshold value away from a front turnout area, and if the train is detected to run to the target point, judging that the front of the train is the turnout area.

That is, the position coordinates of the points on the track line away from the front turnout zone by the first threshold value can be acquired, and the position coordinates of the points are added into the vehicle-mounted electronic map, so that the turnout zone in the place away from the front turnout zone by the position mark of the point can be known. Therefore, when judging whether the front of the train is a turnout area according to the vehicle-mounted electronic map, the current position information can be matched with the position coordinates of each point on the track line in the vehicle-mounted electronic map, if the current position information is matched with the position coordinates of a certain point, whether the train runs to a target point at present is judged, namely, the turnout area exists at the position of the point with a first threshold value in front, and at the moment, the front of the train can be judged to be the turnout area.

As an example of another possible implementation, the onboard electronic map may include the location coordinates of switch zones on the track line. In this example, the specific implementation process of determining whether the front of the train is the turnout zone according to the current position information and the vehicle-mounted electronic map may be as follows: and judging whether a turnout area exists in the advancing direction of the train or not according to the current position information and the position coordinates of the turnout area on the track line in the vehicle-mounted electronic map, if so, judging whether the distance between the current position of the train and the front turnout area is less than or equal to a second threshold value or not according to the current position information and the position coordinates of the front turnout area, and if so, judging that the front of the train is the turnout area.

Optionally, the current position information and the position coordinates of a switch area on the track line in the vehicle-mounted electronic map are compared in size, and whether the switch area exists in the advancing direction of the train is judged according to the comparison result, for example, if the train is running in the west direction, the longitude coordinate in the current position information of the train and the longitude coordinate in the position coordinates of the switch area can be compared in size, if the longitude coordinate in the position coordinates of the switch area is greater than the longitude coordinate in the current position information, it is judged that the switch area exists in the advancing direction of the train, and if the longitude coordinate in the position coordinates of the switch area is less than the longitude coordinate in the current position information, it is judged that the switch area does not exist in the advancing direction of the train. And when the forward direction of the train is judged to have the turnout zone, calculating a distance value between the current position information and the position coordinate of the turnout zone, and judging whether the distance value is less than or equal to a second threshold value, if so, judging that the front of the train is the turnout zone.

And S130, if so, sending the train number information of the train to a target controller beside the track so that the target controller acquires a traffic number from the train number information, acquires a turnout target position corresponding to the turnout area according to the traffic number, locks the turnout when the current position of the turnout is judged to be the target position, and outputs a turnout switching instruction to control the turnout to be pulled to the target position and lock the turnout when the current position of the turnout is judged not to be consistent with the target position.

Optionally, when the front of the train is judged to be the turnout area, the train number information of the train is sent to a target controller beside the rail. Preferably, a target controller is arranged near each turnout zone, so that when the target controller receives train number information sent by a train, the turnout in the turnout zone corresponding to the target controller can be managed and controlled according to a traffic number in the train number information. That is to say, the train only needs to send the train number of the train to the target controller around the train, and the target controller can know that the train is used for managing and controlling the turnouts in the turnout zone matched with the train.

In order to ensure that the target controller receives the train number sent by the train, optionally, in an embodiment of the present invention, after the train number information of the train is sent to the target controller beside the track, whether the train number fed back by the target controller is received or not can be detected to confirm that the message is received, and if not, the train number information of the train is continuously sent to the target controller; and if the information of the train number is received and the message is confirmed to be received, stopping sending the information of the train number.

That is, when the train determines that the front of the train is the switch area, the train starts to transmit the train number information to the target controller. And the target controller immediately feeds back a confirmation result when receiving the train number information. If the train does not receive the confirmation result fed back by the target controller, the train can continuously send the train number information of the train to the target controller, and the train stops sending the train number information until the confirmation result fed back by the target controller is received, so that the target controller can be ensured to receive the train number of the train, and the target controller can realize the management control of the turnout position according to the intersection number in the train number.

It should be noted that, in an embodiment of the present invention, the train number information may include the traffic route number and the sequence number. The crossing refers to a fixed turnover section when the train on the main track runs, namely a section of a circuit when the train runs back and forth from a starting station to a terminal return station, and a crossing number, namely the number of a certain crossing, is a crossing number; the sequence number is used for indicating the current running number of turns of the train. As an example, the train number may consist of a 5-bit character, where the bus number occupies a 2-bit character and the sequence number occupies a 3-bit character. For example, the 2-bit character of the intersection number may be a number or letter: the numeric value range is 1-9; the letter value range A-Z, for example, the intersection number 13, represents the intersection number from the intersection point 1 to the intersection point 3; the intersection number 31 indicates the number of intersections from the intersection point 3 to the intersection point 1. For another example, the 3-bit character of the sequence number may be a number, and may be calculated according to the number of turns of the train running on the line, and the value range is 001 to 999. For example, the train number 13001 represents a train with a traffic number of 13, and the sequence number is 001, that is, the train currently runs 1 turn on the line.

In the embodiment of the present invention, after receiving the train number information sent by the train, the target controller may extract an intersection number from the train number information, and obtain a switch target position in a switch area matched with the target controller according to the intersection number, where the switch target position may be understood as a position where the switch is expected (e.g., positioning or reversing). Then, the target controller can obtain the current position of the turnout and judge whether the current position of the turnout is the target position, if so, the current position of the turnout is considered to be the expected position, and at the moment, the turnout can be directly locked without outputting a command of pulling the turnout; if the current position of the turnout is judged not to be the target position, the current position of the turnout is considered not to be consistent with the expected position, at the moment, a turnout switching instruction (such as a positioning operation instruction or a reverse operation instruction) can be output to control the turnout to be switched to the target position, and after the turnout is switched in place and locked, the turnout position and the locking state of the turnout are fed back to the train.

And S140, controlling the train to enter a turnout zone when receiving the turnout position and locking state fed back by the target controller after locking the turnout.

Optionally, when receiving the switch position and the locking state fed back by the target controller after locking the switch, the train may be considered to be currently allowed to enter the switch zone in front, and at this time, the train may enter the switch zone according to the switch position and the locking state.

Therefore, compared with the automatic train route triggering method used in the traditional urban rail transit signal system, the automatic train route triggering method provided by the embodiment of the invention has the following technical effects:

1) the traditional urban rail transit signal system has high requirements on distance and time when the system is triggered to enter a route, and is seriously dependent on secondary detection equipment such as a rail circuit/axle counting and the like. The invention does not need excessive trackside equipment such as track circuits, axle counting equipment and the like, can completely separate secondary occupation or clearance detection equipment by adopting a precise positioning mode, and the front turnout trip needs to be actively initiated by the vehicle along with the running of the vehicle without the dependence of the trackside equipment.

2) When a front access is opened for a train in the traditional mode, an ATS system comprehensively judges and outputs an instruction for handling the access to an interlocking system according to the train number, destination codes, trigger rails and the like and other related interlocking conditions; the running path of the vehicle is completely determined by the position of the turnout, so that the position of the turnout can be controlled only by controlling the interlocking relationship between the train number and the turnout, and the safety protection between the vehicles is not provided with interval protection by a signal machine and is ensured by a train control system based on vehicle-vehicle communication.

3) According to the train route automatic triggering method provided by the embodiment of the invention, as long as the front of the train is judged to be the turnout zone through the current position information of the train and the vehicle-mounted electronic map, the train sends the train number information of the train to the target controller, so that the target controller obtains the target position of the turnout in the turnout zone according to the train number information, and then controls the turnout according to the target position, and the train is triggered to automatically route; therefore, the automatic train route triggering method can be applied to the main line of the train, the parking lot of the vehicle section and the like without being limited by line application conditions as long as the train judges that the front part is the turnout area; the route of the traditional urban rail transit signal system is automatically triggered and only used on the main line, and the route is generally handled manually in a vehicle section or a parking lot.

4) The automatic route triggering function of the traditional urban rail transit signal system is realized by an ATS system; the automatic train route triggering of the embodiment of the invention is realized by the active initiation of the train.

5) The route triggering of the traditional urban rail transit signal system depends on information such as a table number, a train number, a destination code, a triggering section and the like in the train number information; the train route triggering of the embodiment of the invention depends on the train running traffic number and the marked turnout position in the vehicle-mounted electronic map.

6) The automatic train route triggering in the traditional urban rail transit signal system is handled by an ATS (automatic train supervision); the train actively sends the train number to the target controller, the target controller identifies the train traffic number and switches the turnout for the train, and the path in the corresponding direction is opened, so that the train is in an active status.

7) Because the communication between the target controller and the train does not need to pass through the communication equipment in the dispatching system, the target controller can still trigger automatic route for the train according to the train traffic route number after the communication between the train and the dispatching system is interrupted.

In summary, according to the train route automatic triggering method provided by the embodiment of the invention, when the train runs in the forward direction, the train can judge that the front is a turnout zone according to the self position information, the train number information is sent to the target controller beside the track, the target controller determines the target position of the turnout according to the intersection number in the train number information, and outputs a turnout driving instruction, so that the turnout is pulled to the designated position and locked. In the whole process, firstly, the train actively initiates a request to embody a train control mode taking the train as the center, and under the condition of system failure or reduction of a control center, the operation of a line train cannot be influenced as long as the communication between the train and the target controller is kept; in addition, the train route automatic triggering mode of the embodiment of the invention does not need to depend on too many trackside equipment, optimizes the system architecture of the control center system, simplifies the judgment of the route interlocking condition, and improves the operation efficiency of the train through the interlocking relationship between the train and the turnout.

Corresponding to the train route automatic triggering methods provided in the foregoing embodiments, an embodiment of the present invention further provides a train route automatic triggering device, and since the train route automatic triggering device provided in the embodiment of the present invention corresponds to the train route automatic triggering methods provided in the foregoing embodiments, the implementation manner of the train route automatic triggering method is also applicable to the train route automatic triggering device provided in the embodiment, and is not described in detail in this embodiment. Fig. 2 is a schematic structural diagram of an automatic train route triggering device according to an embodiment of the present invention. It should be noted that the automatic train route triggering device according to the embodiment of the present invention may be applied to a train.

As shown in fig. 2, the automatic train route triggering device 200 may include: a position acquisition module 210, a detection module 220, a train number transmission module 230, and a control module 240.

Specifically, the location obtaining module 210 is configured to obtain current location information of the train.

The detection module 220 is used for judging whether the front of the train is a turnout zone according to the current position information and the vehicle-mounted electronic map. In the embodiment of the present invention, the vehicle-mounted electronic map may be pre-established, and if the contents contained in the vehicle-mounted electronic map are different, the manner of determining whether the front of the train is a turnout area according to the vehicle-mounted electronic map will also be different, and two different examples will be given below:

as an example of one possible implementation, the onboard electronic map may include position coordinates of points on the track line (where the position coordinates may be understood as geographical position coordinates). In this example, the detection module 220 may determine whether the train currently runs to a target point according to the current position information and the position coordinates of each point on the track line in the vehicle-mounted electronic map, where the target point is used to indicate a point away from a front turnout area by a first threshold, and if the train runs to the target point, determine that the front of the train is the turnout area.

As an example of another possible implementation, the onboard electronic map may include the location coordinates of switch zones on the track line. In this example, the detection module 220 may determine whether a switch area exists in the forward direction of the train according to the current position information and the position coordinates of the switch area on the track line in the vehicle-mounted electronic map, and if so, determine whether the distance between the current position of the train and the switch area in front is less than or equal to a second threshold according to the current position information and the position coordinates of the switch area in front, and if so, determine that the switch area is in front of the train.

The train number sending module 230 is configured to send train number information of the train to a target controller located beside a track when the front of the train is judged to be a turnout zone, so that the target controller obtains a traffic number from the train number information, obtains a target position corresponding to a turnout in the turnout zone according to the traffic number, locks the turnout when the current position of the turnout is judged to be the target position, and outputs a turnout switching instruction to control the turnout to be switched to the target position and lock the turnout when the current position of the turnout is judged not to be consistent with the target position.

The control module 240 is configured to control the train to enter the switch zone upon receiving the switch position and the locking state fed back by the target controller after locking the switch.

According to the train route automatic triggering device provided by the embodiment of the invention, a route handling request is initiatively initiated to a target controller beside a rail by the train according to self position information by taking the train as a center, and a turnout switching instruction is directly output by the target controller to realize a turnout pulling mode; in addition, the train route automatic triggering mode of the embodiment of the invention does not need to depend on too many trackside equipment, optimizes the system architecture of the control center system, simplifies the judgment of the route interlocking condition, and improves the operation efficiency of the train through the interlocking relationship between the train and the turnout.

In order to realize the embodiment, the invention also provides another automatic train route triggering method.

Fig. 3 is a flowchart of a train route auto-triggering method according to another embodiment of the present invention. It should be noted that the train route automatic triggering method in the embodiment of the present invention can be applied to a target controller. Wherein, in the embodiment of the present invention, the target controller may be located beside the track. Preferably, a target controller may be disposed near each switch area, so that when the target controller receives train number information sent by a train, the switch in the switch area corresponding to the target controller may be managed and controlled according to a traffic number in the train number information.

As shown in fig. 3, the train route automatic triggering method may include:

and S310, receiving train number information of the train sent by the train, wherein the train number information is sent by the train when the front of the train is judged to be the turnout area, and the train judges whether the front of the train is the turnout area according to the current position information of the list and the vehicle-mounted electronic map.

After the train obtains the current position information of the train, the current position information can be matched with the position coordinates in the vehicle-mounted electronic map so as to detect whether the front of the train is a turnout area. In the embodiment of the present invention, the vehicle-mounted electronic map may be pre-established, and if the contents contained in the vehicle-mounted electronic map are different, the manner of determining whether the front of the train is a turnout area according to the vehicle-mounted electronic map will also be different, and two different examples will be given below:

as an example of one possible implementation, the onboard electronic map may include position coordinates of points on the track line (where the position coordinates may be understood as geographical position coordinates). In this example, the specific implementation process of the train determining whether the front of the train is the turnout area according to the current position information and the vehicle-mounted electronic map may be as follows: and detecting whether the train runs to a target point currently or not according to the current position information and the position coordinates of each point on the track line in the vehicle-mounted electronic map, wherein the target point is used for indicating a point which is a first threshold value away from a front turnout area, and if the train runs to the target point, judging that the front of the train is the turnout area.

As an example of another possible implementation, the onboard electronic map may include the location coordinates of switch zones on the track line. In this example, the specific implementation process of the train determining whether the front of the train is the turnout area according to the current position information and the vehicle-mounted electronic map may be as follows: and judging whether a turnout area exists in the advancing direction of the train or not according to the current position information and the position coordinates of the turnout area on the track line in the vehicle-mounted electronic map, if so, judging whether the distance between the current position of the train and the front turnout area is less than or equal to a second threshold value or not according to the current position information and the position coordinates of the front turnout area, and if so, judging that the front of the train is the turnout area.

In the embodiment of the invention, when the train is judged to be ahead of the turnout zone, the train starts to send the train number information to the target controller. In order to ensure that the target controller receives the train number sent by the train, optionally, after the train sends the train number information to the target controller, the train can detect whether the train number fed back by the target controller is received and confirm the received information, if not, the train number information of the train is continuously sent to the target controller, and if the train number information is received and confirm the received information, the train number information is stopped being sent. That is, the train starts to transmit the train number information to the target controller upon detecting that the train approaches the switch area. And the target controller immediately feeds back a confirmation result when receiving the train number information. If the train does not receive the confirmation result fed back by the target controller, the train can continuously send the train number information of the train to the target controller, and the train stops sending the train number information until the confirmation result fed back by the target controller is received, so that the target controller can be ensured to receive the train number of the train, and the target controller can realize the management control of the turnout position according to the intersection number in the train number.

And S320, acquiring the traffic number from the train number information, and acquiring the target position corresponding to the turnout in the turnout zone according to the traffic number.

Optionally, in the embodiment of the present invention, after receiving the train number information sent by the train, the target controller may obtain the intersection number from the train number information, and then obtain the target position corresponding to the switch in the switch zone according to the intersection number.

As an example, after obtaining a traffic number from the number information of a train, the target controller may obtain an interlocking relationship table of the traffic number and the position of a switch, where the interlocking relationship table includes a correspondence between each traffic number and a target position of a switch in each switch zone, and obtains a switch identifier of the switch zone, and then may find out a target position corresponding to a switch in the switch zone from the interlocking relationship table according to the traffic number and the switch identifier of the switch zone.

For example, an interlocking relationship table of the number of the traffic route and the position of the turnout may be established in advance, and the interlocking relationship table is pre-built in the target controller in the form of a data file. The interlocking relationship table may be loaded into memory when the target controller initializes the data. The interlocking relationship table includes a correspondence between each intersection number and a target position of a switch in each switch zone, for example, the correspondence of the interlocking relationship table may be as shown in table 1 below:

table 1 interlocking relation table of traffic number and switch position

It can be seen that only the relationship between the traffic number and the switch position is in the interlocking relationship table, and the switch position in the interlocking relationship table can be understood as the desired switch position corresponding to the traffic number.

In this embodiment, after obtaining the pre-established interlocking relationship table of the intersection number and the switch position, the switch identifier (such as the switch name, the switch ID, etc.) of the switch zone can be determined by determining which switch zone matches with the target controller, and then the target position corresponding to the switch in the switch zone can be found from the interlocking relationship table according to the intersection number and the switch identifier of the switch zone. For example, if the name of a switch in a determined switch area is P0103 and the traffic number is 13, the target position corresponding to the switch can be found out as "location" according to the name of the switch and the traffic number.

And S330, controlling the turnout in the turnout zone according to the target position.

Optionally, after the target position of the switch is obtained, it may be determined whether the current position of the switch coincides with the target position of the switch, and different controls may be performed on the switch according to the determination result. As an example, the current position of a turnout in the turnout zone can be obtained, whether the current position of the turnout is consistent with the target position or not is judged, and if so, the turnout is locked; and if the current position of the turnout is inconsistent with the target position, outputting a turnout switching instruction to control the turnout to be switched to the target position, and locking the turnout when the turnout is detected to be switched in place.

That is, when the current position of the turnout is judged to be the target position, the current position of the turnout is considered to be the expected position, and at the moment, the turnout can be directly locked without outputting a command for pulling the turnout; if the current position of the turnout is judged not to be the target position, the current position of the turnout is considered not to be consistent with the expected position, at the moment, a turnout switching instruction (such as a positioning operation instruction or a reverse operation instruction) can be output to control the turnout to be switched to the target position, and the turnout is locked when the turnout is detected to be switched in place.

It should be noted that, in the embodiment of the present invention, after the target controller completes the locking operation of the switch points, the switch points do not receive any command for pulling the switch points, so as to ensure the safety of the switch points.

S340, when the turnout is controlled, the turnout position and the locking state of the turnout are obtained, and the turnout position and the locking state are fed back to the train, so that the train enters a turnout area according to the turnout position and the locking state.

According to the train route automatic triggering method provided by the embodiment of the invention, a route handling request is initiatively initiated to a target controller beside a rail by the train by taking the train as a center according to self position information, and a turnout switching instruction is directly output by the target controller to realize a turnout pulling mode; in addition, the train route automatic triggering mode of the embodiment of the invention does not need to depend on too many trackside equipment, optimizes the system architecture of the control center system, simplifies the judgment of the route interlocking condition, and improves the operation efficiency of the train through the interlocking relationship between the train and the turnout.

Fig. 4 is a schematic structural diagram of an automatic train route triggering device according to another embodiment of the present invention. It should be noted that the automatic train route triggering device according to the embodiment of the present invention may be applied to a target controller located beside a track.

As shown in fig. 4, the automatic train route triggering device 400 may include: the train number receiving module 410, the turnout target position obtaining module 420, the turnout control module 430 and the information feedback module 440.

Specifically, the train number receiving module 410 is configured to receive train number information of a train sent by the train, where the train number information is sent by the train when the front of the train is determined to be a switch area, and the train determines whether the front of the train is the switch area according to the current position information and a vehicle-mounted electronic map.

The switch target position obtaining module 420 is configured to obtain a traffic number from the train number information, and obtain a target position corresponding to a switch in the switch area according to the traffic number. As an example, the switch target position obtaining module 420 may obtain a pre-established interlocking relationship table of the traffic numbers and the switch positions, where the interlocking relationship table includes a corresponding relationship between each traffic number and a target position of a switch in each switch zone, and obtains a switch identifier of the switch zone, and then may find out a target position corresponding to a switch in the switch zone from the interlocking relationship table according to the traffic numbers and the switch identifiers of the switch zones.

The switch control module 430 is configured to control switches in the switch zone based on the target location. Optionally, after obtaining the target position of the switch, the switch control module 430 may determine whether the current position of the switch matches the target position of the switch, and perform different control on the switch according to the determination result. As an example, the turnout control module 430 may obtain a current position of a turnout in the turnout zone, determine whether the current position of the turnout is consistent with the target position, and if so, lock the turnout; and if the current position of the turnout is inconsistent with the target position, outputting a turnout switching instruction to control the turnout to be switched to the target position, and locking the turnout when the turnout is detected to be switched in place.

The information feedback module 440 is used for acquiring the switch position and the locking state of the switch when the control of the switch is completed, and feeding the switch position and the locking state back to the train, so that the train enters the switch area according to the switch position and the locking state.

In order to realize the embodiment, the invention further provides an automatic train route triggering system.

Fig. 5 is a schematic structural diagram of an automatic train route triggering system according to an embodiment of the present invention. As shown in fig. 5, the automatic train route triggering system 500 may include: a train 510 and a target controller 520 located trackside. Preferably, a target controller 520 may be disposed near each switch area, so that when the target controller 520 receives the train number information sent by the train 510, the switch in the switch area corresponding to the target controller 520 may be managed and controlled according to the traffic number in the train number information.

Specifically, the train 510 is configured to obtain current position information, determine whether the front of the train 510 is a turnout zone according to the current position information and the vehicle-mounted electronic map, and send the train number information to the target controller 520 when determining that the front of the train 510 is the turnout zone.

The target controller 520 is configured to receive train number information sent by the train 510, obtain a traffic number from the train number information, obtain a target position corresponding to a switch in the switch area according to the traffic number, control the switch in the switch area according to the target position, obtain a switch position and a locking state of the switch when the control of the switch is completed, and feed back the switch position and the locking state to the train 510.

The train 510 is also used to enter the switch zone based on the switch position and the locked state.

It should be noted that the vehicle-mounted electronic map may be pre-established, and if the contents contained in the vehicle-mounted electronic map are different, the manner of determining whether the front of the train is the turnout area according to the vehicle-mounted electronic map may also be different, and two different examples will be given below:

as an example of one possible implementation manner, the vehicle-mounted electronic map may include position coordinates of each point on the track line, wherein in this example, a specific implementation process of the train 510 determining whether the front of the train 510 is a switch area according to the current position information and the vehicle-mounted electronic map may be as follows: detecting whether the train 510 runs to a target point currently according to the current position information and the position coordinates of each point on the track line in the vehicle-mounted electronic map, wherein the target point is used for indicating a point which is a first threshold value away from a front turnout area; if the train 510 is traveling to the target point, it is determined that the switch zone is ahead of the train 510.

As an example of another possible implementation, the onboard electronic map may include the location coordinates of switch zones on the track line. In this example, the specific implementation process of the train 510 determining whether the front of the train 510 is a turnout area according to the current location information and the vehicle-mounted electronic map may be as follows: judging whether a turnout area exists in the advancing direction of the train 510 according to the current position information and the position coordinates of the turnout area on the track line in the vehicle-mounted electronic map; if the current position information exists, judging whether the distance from the current position of the train 510 to the front turnout area is smaller than or equal to a second threshold value according to the current position information and the position coordinates of the front turnout area; if yes, the front of the train 510 is determined to be the turnout zone.

Optionally, in the embodiment of the present invention, after receiving the train number information sent by the train 510, the target controller 520 may obtain an intersection number from the train number information, and then obtain a target position corresponding to a switch in the switch zone according to the intersection number.

As an example, the specific implementation process of the target controller 520 obtaining the target position corresponding to the switch in the switch zone according to the traffic number may be as follows: the method comprises the steps of obtaining a pre-established interlocking relationship table of traffic numbers and turnout positions, wherein the interlocking relationship table comprises the corresponding relationship between each traffic number and the target position of a turnout in each turnout zone, obtaining turnout identifications of the turnout zones, and finding out the target position corresponding to the turnout in the turnout zone from the interlocking relationship table according to the traffic numbers and the turnout identifications of the turnout zones.

In an embodiment of the present invention, after obtaining the target position of the switch, the target controller 520 may determine whether the current position of the switch coincides with the target position of the switch, and perform different control on the switch according to the determination result. As an example, the target controller 520 may obtain a current position of a switch in the switch zone, and determine whether the current position of the switch is consistent with the target position, and if the current position of the switch is consistent with the target position, lock the switch; and if the current position of the turnout is inconsistent with the target position, outputting a turnout switching instruction to control the turnout to be switched to the target position, and locking the turnout when the turnout is detected to be switched in place.

In order that those skilled in the art will more clearly understand the present invention, the following description will be given by way of example. In this example, it is assumed that the present invention adopts a line topology as shown in fig. 6 to describe operations such as road crossing and train number.

For example, taking the train 31004, the train number 31004, the intersection number 31, and the traveling direction as the intersection points 3 to 1 as shown in fig. 6 as an example, the automatic route triggering process of the train 31004 may be as follows:

1) the train 31004 runs on the line and calculates the position in real time;

2) the train 31004 periodically detects whether the position of the train is a trigger point for sending the train number in the turnout zone in the vehicle-mounted electronic map, and when the train is detected to run to the position A1, the train sends the train number 31004 to the target controller. And the target controller immediately feeds back a confirmation result after receiving the train number. The a1 location may be understood as the trigger point in the on-board electronic map that identifies the train's start of sending a train number.

3) The train 31004 stops transmitting the train number when receiving the confirmation result.

4) The target controller obtains the traffic route number 31 according to the train number 31004, and inquires the expected position of the turnout P0103 corresponding to the traffic route number 31 as positioning from the built-in interlocking relationship table (for example, the table 1) of the traffic route number and the turnout position;

5) the target controller compares the real-time position of the turnout P0103, and if the real-time position is a reverse position and is inconsistent with the expected position at the moment, the target controller outputs a positioning operation instruction to a point switch for controlling the turnout P0103, and the point switch drives the turnout to be switched to positioning and gives locking;

6) the target controller sends the turnout position and the locking state to the train 31004, and the train 31004 obtains turnout operation permission and safely moves forward to the turnout zone. The exemplary diagram of the scenario can be shown in fig. 7.

According to the train route automatic triggering system provided by the embodiment of the invention, a route handling request is initiatively initiated to a target controller beside a rail by the train according to self position information by taking the train as a center, and a turnout switching instruction is directly output by the target controller to realize a turnout pulling mode; in addition, the train route automatic triggering mode of the embodiment of the invention does not need to depend on too many trackside equipment, optimizes the system architecture of the control center system, simplifies the judgment of the route interlocking condition, and improves the operation efficiency of the train through the interlocking relationship between the train and the turnout.
