Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method for handing over the path of the degraded train provided by the invention is based on a train control system of vehicle-to-vehicle communication, the running path of the degraded train is planned, and the line resource of the running path of the degraded train is released after the degraded train drives out of the running path of the degraded train, which is equivalent to providing virtual blocking control for the degraded train, so that the degraded train and the normal train do not influence each other in running. The method for handing over the degraded train path provided by the invention provides a stable and reliable handover scheme for handling the degraded train path between the OC based on the communication between Object Controllers (OC), and comprises the steps of performing handover command interaction on the degraded train path between the OC and the OC, completing handover of a master control OC of a degraded train, enabling the degraded train path to smoothly run to the next OC and continue handling when crossing the OC, and solving the problem of acquiring the degraded train path, wherein the method is specifically realized as follows:
fig. 1 is a schematic flow chart of a degraded train path handover method provided by the present invention, and as shown in fig. 1, the method includes:
It should be noted that the execution subject of the method may be a computer device, or may be a second object controller OC, and the second object controller OC is taken as an example to execute the method, so as to describe in detail the degraded train route handover method provided by the present invention.
Optionally, the present invention provides a method for handover of a degraded Train path based On inter-OC communication based On a Train control system based On inter-Vehicle communication, where the related system includes an existing Object Controller (OC) of a Vehicle, an Intelligent Train monitoring system (ITS) and an On-Board Controller (IVOC), where the IVOC is further divided into subsystems: an Intelligent Train Protection system ITP (ITP) and an Intelligent Train operation system (ITO). The vehicle-mounted controller IVOC mainly ensures the running safety of the train, plans a running path, and has the functions of vehicle-mounted interlocking, vehicle-mounted moving block and the like.
In the train-to-vehicle communication system, a train is degraded due to a communication failure between the train and a first object controller OC (see fig. 2, OC1), and the first object controller OC plans a running path for each degraded train to ensure that the degraded train runs safely in the running path. When the train runs out of the degraded train running path and needs to reach the adjacent OC (namely the second object controller OC, see the OC2 in the figure 2), the adjacent OC synchronizes the degraded train path information, and the degraded train path in the OC (namely the second object controller OC) is continuously planned for the degraded train. In order to synchronize the degraded train path information of the first object controller OC with the adjacent second object controller OC. The first object controller OC and the adjacent second object controller OC complete the path information synchronization of the degraded train in a command interaction and state machine conversion mode. The following steps introduce a specific process of command interaction:
the second object controller OC receives a first request message sent by the first object controller OC, and the first request message may specifically be a handover application of the operation path of the degraded train, and is used for requesting handover of the operation path of the degraded train.
After receiving the first request message of the first object controller OC (i.e., the master control OC), the second object controller OC (adjacent OC) checks whether the downgraded train is located at the boundary of the master control OC, specifically, by judging whether the current destination of the downgraded train is located at the boundary of the master control OC and the adjacent OC, if it is determined that the downgraded train is located at the boundary of the master control OC, the second object controller OC sends the first response message to the first object controller OC once, and simultaneously sends the second request message to the first object controller OC, where the second request message may specifically be a handover execution application for requesting execution of an operation of handing over an operation path of the downgraded train.
After receiving the second request message, the first object controller OC sends a second response message to the second object controller OC, where the second response message may specifically be a handover execution application reply (see fig. 3) for responding to the second request message. And after receiving the second response message, the second object controller OC calculates an extension condition for the degraded train and continues to plan a subsequent operation path for the degraded train.
The degraded train path handover method provided by the invention optimizes the mode of manually driving the train after the train is degraded in the existing train control system, realizes handover of the running path after the degraded train based on communication between the OCs, plans the running path of the degraded train, releases the line resource of the running path after the degraded train drives out of the running path, equivalently provides virtual block control for the degraded train, ensures that the degraded train and the normal train do not influence each other, and improves the operation efficiency.
Further, in an embodiment, after sending the first response message and the second request message to the first OC, the method may further specifically include:
and changing the state of the second OC from the idle state to a state waiting for the last reply.
Optionally, referring to fig. 4, after receiving the first request message of the first object controller OC (i.e., the master OC), the second object controller OC (the adjacent OC) checks whether the downgraded train is located at the boundary of the master OC, and if it is determined that the downgraded train is located at the boundary of the master OC, the second object controller OC sends the first response message to the first object controller OC once, and sends the second request message to the first object controller OC at the same time, and changes the state of the second object controller OC from the idle state to the waiting state for the last reply.
The degraded train path handover method provided by the invention optimizes the mode of manually driving the train after the train is degraded in the existing train control system, realizes handover of the running path after the train is degraded based on communication and state conversion among the OCs, plans the running path of the degraded train, releases the line resource of the running path after the degraded train drives out of the running path, equivalently provides virtual block control for the degraded train, ensures that the degraded train and the normal train do not influence each other, and improves the operation efficiency.
Further, in an embodiment, after receiving the second response message sent by the first OC, the method may further specifically include:
changing the state of the second OC from the last recovery state to an idle state;
the second OC is changed to the first OC.
Optionally, referring to fig. 4, after receiving the first request message of the first object controller OC (i.e., the master OC), the second object controller OC (the adjacent OC) checks whether the downgraded train is located at the boundary of the master OC, and if it is determined that the downgraded train is located at the boundary of the master OC, the second object controller OC sends the first response message to the first object controller OC once, and sends the second request message to the first object controller OC at the same time, and changes the state of the second object controller OC from the idle state to the waiting state for the last reply.
After receiving the second request message, the first object controller OC sends a second response message to the second object controller OC (see fig. 3), and after receiving the second response message, the second object controller OC changes the state of the second controller OC from the state of waiting for the last reply to the idle state, and changes the second controller OC to the first object controller OC (i.e., the master control OC), and calculates the extension condition for the degraded train in the idle state.
And after the second object controller OC is updated to the main control OC, continuing to plan the operation path for the degraded train. And after the original first object controller OC receives the degraded train running path after the adjacent OC finishes planning, opening a signal machine in front of the degraded train running path, and after a driver identifies that the signal in front is a green light, driving the train to enter the next centralized area.
Referring to fig. 7, by the above method, the master OC of the movement path of the degraded train can be smoothly switched to the destination OC, that is, the adjacent OC, and the adjacent OC continues to plan the movement path for the degraded train. And after receiving the planned running path, the original main control OC opens a signal for the train.
The method for handing over the path of the degraded train provided by the invention provides a stable and reliable handing over scheme for handling the operation path of the degraded train between the OCs based on communication and state conversion between the OCs, so that the operation path of the degraded train can smoothly run to the next OC and continue handling when the OC is crossed, the degraded train and normal train operation are not influenced by each other, and the operation efficiency is improved.
Fig. 5 is a second flowchart of the method for transferring a downgraded train path according to the present invention, and as shown in fig. 5, the method includes:
It should be noted that the execution subject of the method may be a computer device, or may be the first object controller OC, and the first object controller OC is taken as an example to execute the method, so as to describe in detail the degraded train route handover method provided by the present invention.
Optionally, the present invention provides a method for handover of a degraded Train path based On inter-OC communication based On a Train control system based On inter-Vehicle communication, where the related system includes an existing Object Controller (OC) of a Vehicle, an Intelligent Train monitoring system (ITS) and an On-Board Controller (IVOC), where the IVOC is further divided into subsystems: an Intelligent Protection system ITP (ITP) for a Train, and an Intelligent driving system (ITO) for a Train.
In the train-to-vehicle communication system, a train is degraded due to a communication failure between the train and a first object controller OC (see fig. 2, OC1), and the first object controller OC plans a running path for each degraded train to ensure that the degraded train runs safely in the running path. When the train runs out of the degraded train running path and needs to reach the adjacent OC (namely the second object controller OC, see the OC2 in the figure 2), the adjacent OC synchronizes the degraded train path information, and the degraded train path in the OC (namely the second object controller OC) is continuously planned for the degraded train. In order to synchronize the degraded train path information of the first object controller OC with the adjacent second object controller OC. The first object controller OC and the adjacent second object controller OC complete the path information synchronization of the degraded train in a command interaction and state machine conversion mode. The following steps introduce a specific process of command interaction:

The second OC can synchronize the movement path of the degraded train after the handover of the movement path of the degraded train.
Referring to fig. 3, the first object controller OC receives the first response message and the second request message sent by the second controller OC, and after the handover is completed, the second object controller OC sends a second response message to the second object controller OC, where the second response message may specifically be a handover execution application reply, and is used to calculate an extension condition for the downgraded train and continue to plan a subsequent operation path for the downgraded train after the second object controller OC receives the second response message in response to the second request message.
After receiving the movement path of the degraded train planned by the second object controller OC (i.e., updated), the first object controller OC opens a signal for degrading the train, specifically, opens a signal machine in front of the movement path of the degraded train, and after recognizing that the signal in front is a green light, the driver drives the train to enter the next concentration area.
The degraded train path handover method provided by the invention optimizes the mode of manually driving the train after the train is degraded in the existing train control system, realizes handover of the running path after the degraded train based on communication between the OCs, plans the running path of the degraded train, releases the line resource of the running path after the degraded train drives out of the running path, equivalently provides virtual block control for the degraded train, ensures that the degraded train and the normal train do not influence each other, and improves the operation efficiency.

and if the first response message sent by the second OC is not received within the communication interruption time, changing the state of the first OC from the initiating waiting state to the idle state, and resending the first request message to the second OC.
Optionally, referring to fig. 2, after the first object controller OC (i.e., the master OC) sends the first request message to the second object controller OC (i.e., the adjacent OC), the state of the master OC is changed from the idle state to the initiation waiting state, and if the first response message is not received within the communication interruption time, the master OC automatically returns to the idle state, and sends the first request message to the second object controller OC again to perform a new path planning.

and after receiving a second request message sent by the second OC, updating the state of the first OC from the timing waiting state to an idle state, and changing the first OC into the second OC.
Optionally, referring to fig. 6, after receiving the first request message of the first object controller OC (i.e., the master OC), the second object controller OC (the adjacent OC) checks whether the downgraded train is located at the boundary of the master OC, and if it is determined that the downgraded train is located at the boundary of the master OC, the second object controller OC sends the first response message to the first object controller OC once, and sends the second request message to the first object controller OC at the same time, and changes the state of the second object controller OC from the idle state to the waiting state for the last reply.

And after the original first object controller OC receives the degraded train running path after the adjacent OC finishes planning, opening a signal machine in front of the degraded train running path, and after a driver identifies that the signal in front is a green light, driving the train to enter the next centralized area.
Referring to fig. 7, by the above method, the master OC of the degraded train operation path can be smoothly switched to the destination OC, that is, the adjacent OC, and the adjacent OC continues to plan the operation path for the degraded train (that is, update the degraded train path). And after receiving the planned running path, the original main control OC opens a signal for the train.
