The handover takeover method of the flexible consist train in the zone controller overlapping zone of the present invention is described below with reference to fig. 1 to 10.
The flexible marshalling train refers to a coupling and uncoupling operation of a plurality of basic unit trains, and comprises a first train 10 and a second train 20.
The first train 10 is located at the forefront of the direction of travel of the flexible consist train, i.e. the first train 10 is the lead train in the flexible consist train and the second train 20 follows the first train 10.
The first train 10 is a master train of the flexible consist trains, the second train 20 is a slave train of the flexible consist trains, and the second train 20 may be one or more.
The main control vehicle cab is activated to provide power and actively run forward; the controlled car cab is not activated, is dragged by the master control car and runs forward passively.
A first zone controller and a second zone controller are arranged along the travel direction of the flexible consist train, the first zone controller being located upstream of the travel direction and the second zone controller being located downstream of the travel direction.
The jurisdiction of the first zone controller and the jurisdiction of the second zone controller overlap to form an overlap zone, and the overlap boundary of the overlap zone includes a first boundary and a second boundary.
The first boundary is a boundary at one side of the first area controller, the second boundary is a boundary at one side of the second area controller, the handover boundary is positioned between the first boundary and the second boundary, and the flexible marshalling train sequentially passes through the first boundary, the handover boundary and the second boundary.
The first zone controller is a handover zone controller, the second zone controller is a takeover zone controller, and the handover boundary is a boundary for switching control rights of the flexibly grouped train from the handover zone controller to the takeover zone controller.
The following describes a handover takeover method of the flexible consist train applied to the first train 10 in the area controller overlapping area.
As shown in fig. 1, the handover takeover method of the flexibly grouped trains applied to the first train 10 in the overlapping area of the area controller includes steps 110 to 140, and the execution subject of the method may be the controller of the first train 10, or the cloud or the edge server.
Step 110, determining that the maximum safe front end of the second train 20 passes through the first boundary, establishing communication with the second zone controller and registering train information, and operating based on the first movement authorization sent by the first zone controller.
The first train 10 and the second train 20 each have a safety envelope for ensuring safe driving, and the safety envelope is a section of safety interval defined by a maximum safety front end and a minimum safety rear end of the train.
In this embodiment, the flexibly grouped trains travel toward the overlapping area, first enter the jurisdiction area corresponding to the first area controller in the overlapping area, the maximum safe front end and the minimum safe rear end of the first train 10 travel over the first boundary, when the maximum safe front end of the second train 20 travels over the first boundary, the first train 10 establishes communication with the second area controller and registers train information, and the first train 10 operates based on the first movement authority transmitted by the first area controller.
The first movement authorization is a train control message that is sent to the first train 10 by the first zone controller in a calculation cycle and can be used for controlling the operation of the first train 10.
It will be appreciated that the first train 10 establishes communication with the first zone controller and registers train information as the flexibly consist trains travel in the jurisdiction of the first zone controller or in the jurisdiction corresponding to the first zone controller in the overlap zone before the maximum safe front end of the second train 20 passes the first boundary, the first train 10 operating based on the first movement authority sent by the first zone controller.
In this embodiment, when the maximum safe front end of the second train 20 passes the first boundary, the first train 10 establishes communication with the second zone controller and registers train information, at which time the first train 10 maintains communication link with both the first zone controller and the second zone controller, and the first train 10 is fully controlled by the first movement authority transmitted from the first zone controller.
Step 120, determining that the minimum safe rear end of the second train 20 passes the first boundary, and the end position of the first movement authority reaches the handover boundary, and operating based on the target movement authority sent by the first zone controller.
The movement authorization refers to a driving permission range, the first movement authorization includes a start position and an end position, the start position corresponds to a current position of the first train 10, the end position corresponds to a position that the first train 10 can reach, the first movement authorization is sent to the first train 10 through a calculation period performed by the first area controller, and the start position and the end position of the first movement authorization are updated in real time.
In this embodiment, the flexible consist trains travel from the jurisdiction corresponding to the first zone controller in the overlap zone toward the jurisdiction corresponding to the second zone controller in the overlap zone, the maximum safe front end of the second train 20 passes the first boundary, and when the minimum safe rear end of the second train 20 passes the first boundary and the end position of the first movement authority reaches the handover boundary, the first train 10 operates based on the target movement authority transmitted by the first zone controller, and the control authority handover flow from the handover zone controller to the takeover zone controller for the flexible consist trains is started.
The target movement authorization is determined based on the first movement authorization and the second movement authorization, the first train 10 is simultaneously communicated with the first area controller and the second area controller, the first area controller and the second area controller calculate movement authorization information for the first train 10, the first movement authorization and the second movement authorization are respectively calculated by the first area controller, the first area controller splices the first movement authorization and the second movement authorization calculated by the first area controller, and the obtained target movement authorization is sent to the first train 10.
Step 130, determining that the minimum safe back end of the first train 10 passes through the handover boundary, disconnecting communication with the first zone controller and logging out train information, and operating based on the second movement authorization sent by the second zone controller.
In this step, the handover procedure is normally performed, and when the minimum safe rear end of the first train 10 passes the handover boundary, that is, the first train 10 completely passes the jurisdiction corresponding to the first zone controller in the overlapping zone, the first train 10 is disconnected from the first zone controller and the train information is logged off, and the first train 10 operates based on the second movement authority transmitted by the second zone controller.
In this embodiment, after the maximum safe front end of the first train 10 passes the handover boundary, the first train 10 is selected to operate based on the first movement authority or to operate based on the second movement authority according to its real-time operation position before the minimum safe rear end of the first train 10 passes the handover boundary.
Step 140, determining that the starting point position of the first mobile authorization crosses the handover boundary and is at a target distance from the handover boundary, and ending the handover procedure.
After the first train 10 is disconnected from the first zone controller, the first zone controller acquires the position information of the first train 10 through the second zone controller, and continues to calculate the first movement authorization for the first train 10, where the first movement authorization is included in the information sent to the first train 10 by the second zone controller.
In this step, the flexible-grouping train continues to travel, and after the first zone controller calculates the start position of the first movement authority for the first train 10 to cross the handover boundary target distance, it is determined that the handover procedure is ended, and the flexible-grouping train control authority is switched from the first zone controller to the second zone controller.
According to the handover takeover method of the flexibly grouped trains in the overlapping area of the area controllers, the movement authorization of the master control vehicle calculated by the first area controller and the second area controller is spliced, so that the first train 10 stably runs in the overlapping area from the jurisdiction area corresponding to the first area controller to the jurisdiction area corresponding to the second area controller, and the control right of the flexibly grouped trains is switched from the handover area controller to the takeover area controller.
It should be noted that, the method for handing over and taking over the flexibly grouped trains in the overlapping area of the area controller provided by the embodiment of the invention is also applicable to handing over and taking over the control right of the fixedly grouped trains.
In this embodiment, the switch status packet, the physical section status packet, the handover train packet, the track section train sequencing packet, the handover status packet, and the like are periodically transmitted between the first zone controller and the second zone controller.
The first zone controller calculates a first movement authorization based on the handover train information packet, the track section train sort information packet, and the handover status information packet transmitted with the second zone controller, and the real-time position information of the first train 10.
The second zone controller calculates a second movement authorization based on the handover train information packet, the track section train sort information packet, and the handover status information packet transmitted with the second zone controller, and the real-time position information of the first train 10.
The first area controller and the second area controller are communicated with each other, and the first area controller splices the first movement authorization with the second movement authorization to obtain the target movement authorization.
It should be noted that, as the handover procedure proceeds, the content and type of the periodically transmitted packet between the first zone controller and the second zone controller may vary.
The transmission period of periodically transmitting the handover train information packet and the track section train sequencing information packet between the first area controller and the second area controller is as follows:
the period from the maximum safe front end of the first train 10 traveling past the first boundary to the minimum safe rear end of the second train 20 traveling past the handoff boundary.
The handover train packet and the track section train sequencing packet transmitted between the first zone controller and the second zone controller are packets containing information about the flexibly-grouped trains in a period from when the maximum safe front end of the first train 10 passes through the first boundary to when the minimum safe rear end of the second train 20 passes through the handover boundary.
When the minimum safe rear end of the second train 20 passes through the handover boundary, after the minimum safe rear end passes away from the jurisdiction area corresponding to the first area controller in the overlapping area, the information packet of the handover train information type and the track section train sequencing information type transmitted between the first area controller and the second area controller does not contain the related information of the flexibly grouped trains passing through the handover boundary.
The transmission period for periodically transmitting the handover state information packet between the first zone controller and the second zone controller is:
the end position of the first mobile grant reaches the handover boundary to a time period in which the start position of the first mobile grant crosses the handover boundary and is a target distance from the handover boundary.
When the minimum safe rear end of the second train 20 passes through the handover boundary, and leaves the jurisdiction corresponding to the first zone controller in the overlapping zone, the handover procedure is terminated, and the handover status packet is not periodically transmitted between the first zone controller and the second zone controller.
The following describes a handover takeover method of the flexible consist train applied to the second train 20 in the zone controller overlapping zone.
The second train 20 is used as a controlled train, and passively runs forward, and does not need to receive train control messages such as movement authorization sent by the regional controllers, and the communication link is kept communicated with the corresponding regional controllers by receiving special control messages with smaller data quantity.
The special control message received by the second train 20 includes the special control command and path information.
The special control command is used for judging whether the second train 20 performs emergency braking, and since the second train 20 is a controlled train, the cab is not activated, the forward movement and braking of the second train are controlled by the drag of the first train 10 of the master train, and the second train 20 does not respond to the special control command and does not perform active emergency braking measures.
The path information may provide information of all switches within a certain distance in the running direction of the second train 20, and when the second train 20 detects that a certain switch passes, the actual running direction (positioning/reversing) of the train is judged by the switch state information of the switch in the path information, so as to obtain a real-time running position, that is, the current train position.
In this embodiment, the special control message received by the second train 20 from the zone controller is used to keep the communication link with the corresponding zone controller, and determine the forward direction of the train through the switch state in the path information, so as to obtain the real-time running position.
As shown in fig. 2, the handover takeover method of the flexible consist train applied to the second train 20 in the overlapping area of the area controller includes steps 210 to 230, and the execution subject of the method may be the controller of the second train 20, or the cloud or the edge server.
Step 210, determining that the minimum safe rear end of the second train 20 passes through the first boundary, and the end position of the first movement authorization of the first zone controller reaches the handover boundary, establishing communication with the second zone controller and registering train information, and running based on the first special control message sent by the first zone controller.
In this embodiment, the flexible consist trains travel from jurisdictions corresponding to the first zone controller to jurisdictions corresponding to the second zone controller in the overlapping zone, the maximum safe front end of the second train 20 travels over the first boundary, when the minimum safe rear end of the second train 20 travels over the first boundary and the end position of the first movement authority reaches the handover boundary, the second train 20 establishes communication with the second zone controller and registers train information, and the second train 20 receives and operates based on the first special control message transmitted by the first zone controller.
It will be appreciated that the second train 20 establishes communication with the first zone controller and registers train information as the flexibly consist trains travel in the jurisdiction of the first zone controller or in the jurisdiction corresponding to the first zone controller in the overlap zone before the minimum safe rear end of the second train 20 passes the first boundary, based on the first special control message transmitted by the first zone controller.
Step 220, determining that the maximum safe front end of the first train 10 passes through the handover boundary, and running based on the first special control message or the second special control message sent by the second zone controller according to the real-time running position of the second train 20.
When the minimum safe rear end of the second train 20 passes the first boundary and the end position of the first movement authority reaches the handover boundary, the first train 10 operates based on the target movement authority transmitted from the first zone controller, and the handover procedure is started.
The handover procedure is normally performed, and when the maximum safe front end of the first train 10 passes through the handover boundary, the second train 20 selects according to its own real-time operation position, and operates based on the first special control message transmitted by the first zone controller or operates based on the second special control message transmitted by the second zone controller.
Step 230, determining that the minimum safe back end of the second train 20 passes through the handover boundary, disconnecting communication with the first zone controller and logging out train information, and operating based on the second special control message.
In this step, the flexible consist train continues to travel, and when the minimum safe rear end of the second train 20 passes the handover boundary, the second train 20 disconnects from the first zone controller and cancels the train information, and the second train 20 operates based on the second special control message transmitted from the second zone controller.
According to the handover takeover method of the flexible marshalling train in the overlapping area of the area controllers, through establishment and disconnection of the communication link and selection of the special control message, the second train 20 stably runs from the jurisdiction area corresponding to the first area controller to the jurisdiction area corresponding to the second area controller under traction of the first train 10, so that the control right of the flexible marshalling train is switched from the handover area controller to the takeover area controller.
A specific embodiment is described below.
When the flexible marshalling train does not enter the overlapped area, the end position of the first movement authority calculated by the first area controller for the first train 10 is not considered, the handover process is not started, the first train 10 and the second train 20 only establish communication with the first area controller and register, and the flexible marshalling train is completely controlled by the first area controller.
The first train 10 uses a first movement authorization MA1 sent by the first zone controller, and the first movement authorization uses a first special control message sent by the first zone controller.
As shown in fig. 3, the maximum safety front end of the safety envelope of the first train 10 enters the jurisdiction corresponding to the first zone controller in the overlap zone, i.e., the zone from the first boundary to the handover boundary in the figure.
The handover procedure is not started, the first train 10 and the second train 20 establish communication with and register only with the first zone controller, and the flexible consist trains are fully controlled by the first zone controller.
As shown in fig. 4, the first train 10 security envelope completely enters the jurisdiction corresponding to the first zone controller in the overlap zone, and the maximum security front end of the second train 20 security envelope passes through the first boundary and enters the jurisdiction corresponding to the first zone controller.
The first zone controller calculates that the end position of the first movement authority MA1 calculated for the first train 10 does not reach the handover boundary, the handover procedure is not started, the first train 10 and the second train 20 establish communication with the first zone controller only and register, and the flexible marshalling train is completely controlled by the first zone controller.
