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.
According to the degraded train path handover method, the running path of the degraded train is planned based on the train control system of the train communication, and the line resources of the running path of the degraded train are released after the degraded train exits the running path of the degraded train, which is equivalent to providing virtual blocking control for the degraded train, so that the operation of the degraded train and the normal train are not affected. The degraded train path handover method provided by the invention provides a stable and reliable handover scheme for handling the degraded train path among the OC based on the communication among the object controllers (Object Controller, OC), and comprises the steps of performing the handover command interaction of the degraded train path between the OC and the OC, completing the handover of the degraded train master control OC, enabling the degraded train path to smoothly run to the next OC and continue handling when crossing the OC, solving the signal acquisition problem of the degraded train path, and specifically realizing the following steps:
Fig. 1 is a schematic flow chart of a degraded train path handover method provided by the present invention, as shown in fig. 1, the method includes:
step 100, receiving a first request message sent by a first object controller OC, where the first request message is used to request handover of a running path of a degraded train;
Step 200, when determining that the degraded train is located at the boundary of the first OC, sending a first response message and a second request message to the first OC, wherein the first response message is used for responding to the first request message, and the second request message is used for requesting to execute the operation of handing over the running path of the degraded train;
And 300, receiving a second response message sent by the first OC, updating the running path of the degraded train, and sending the updated running path of the degraded train to the first OC, wherein the second response message is used for responding to the second request message.
The main execution body of the method may be a computer device or a second object controller OC, and the method is executed by the second object controller OC as an example, and the degraded train path handover method provided by the present invention is described in detail below.
Optionally, the present invention provides a degraded train path handover method based On an inter-OC communication based train control system, wherein the related system includes an existing object Controller (Object Controller, OC), a train intelligent monitoring system (INTELLIGENT TRAIN Supervision, ITS) and an On-Board Controller (INTELLIGENT VEHICLE On-Board Controller, IVOC), and IVOC is divided into subsystems: train intelligent Protection system ITP (INTELLIGENT TRAIN Protection, ITP), train intelligent driving system (INTELLIGENT TRAIN Operationn, ITO). The vehicle-mounted controller IVOC mainly ensures the running safety of the train, plans the driving path and has the functions of vehicle-mounted interlocking, vehicle-mounted moving blocking and the like.
In the train communication system, a train is degraded due to communication failure between the train and a first object controller OC (see fig. 2, OC 1), which plans a running path for each degraded train to ensure safe running of the degraded train in the running path. The train running in the degraded train running path needs to arrive at the adjacent OC (i.e., the second object controller OC, see fig. 2, OC 2), and the degraded train path information needs to be synchronized by the adjacent OC to continue planning the degraded train path in the present OC (i.e., the second object controller OC) for the degraded train. To synchronize the degraded train path information of the first object control OC with the adjacent second object control 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 mode and a state machine conversion mode. The following steps introduce the specific process of command interaction:
The second object controller OC receives a first request message, which may be specifically a handover application for downgraded train operation path, sent by the first object controller OC, for requesting handover of the downgraded train operation path.
After receiving the first request message of the first object controller OC (i.e., the master OC), the second object controller OC (adjacent OC) checks whether the degraded train is located at the boundary of the master OC, specifically, whether the current end point of the degraded train is located at the boundary point of the master OC and the adjacent OC can be judged, if the degraded train is determined to be located at the boundary of the master OC, the second object controller OC sends a first response message to the first object controller OC, and simultaneously sends a second request message to the first object controller OC, wherein the second request message can be specifically a handover execution application for requesting to execute an operation of handing over the running path of the degraded train.
After receiving the second request message, the first object controller OC sends a second response message, which may be specifically a handover execution application reply (see fig. 3), to the second object controller OC, for responding to the second request message. 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 travel path for the degraded train.
According to the degraded train path handing over method provided by the invention, the mode that the train in the existing train control system depends on the manual driving train after being degraded is optimized, the handing over of the running path after the degraded train is realized based on inter-OC communication, the running path of the degraded train is planned, and the line resources of the running path are released after the degraded train exits the running path, which is equivalent to providing virtual blocking control for the degraded train, so that the operation of the degraded train and the normal train is not affected, and the operation efficiency is improved.
Further, in one embodiment, after the first response message and the second request message are sent to the first OC, the method may further specifically include:
Changing the state of the second OC from the idle state to the wait for last reply state.
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 (adjacent OC) checks whether the degraded train is located at the boundary of the master OC, and if it is determined that the degraded train is located at the boundary of the master OC, the second object controller OC transmits a first response message to the first object controller OC, and simultaneously transmits a second request message to the first object controller OC, and changes the state of the second object controller OC from the idle state to the waiting state for the last reply.
According to the degraded train path handing over method provided by the invention, the mode that the train is degraded and then depends on a manual driving train in the existing train control system is optimized, the handing over of the running path after the degraded train is realized based on inter-OC communication and state conversion, the running path of the degraded train is planned, and the line resources of the running path are released after the degraded train exits the running path, which is equivalent to providing virtual blocking control for the degraded train, so that the operation of the degraded train and the normal train are not affected, and the operation efficiency is improved.
Further, in one 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 replying 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 (adjacent OC) checks whether the degraded train is located at the boundary of the master OC, and if it is determined that the degraded train is located at the boundary of the master OC, the second object controller OC transmits a first response message to the first object controller OC, and simultaneously transmits a second request message to the first object controller OC, and changes the state of the second object controller OC from the idle state to the waiting state for the last reply.
After the first object controller OC receives the second request message, the second object controller OC sends a second response message to the second object controller OC (see fig. 3), and after the second object controller OC receives the second response message, the state of the second object controller OC is changed from the waiting state for the last reply to the idle state, and the second object controller OC is changed to the first object controller OC (i.e., the master OC), and the extension condition is calculated for the degraded train in the idle state.
After the second object controller OC is updated to the master OC, the planning of the travel path for the degraded train is continued. After the original first object controller OC receives the degraded train running path after the adjacent OC planning is completed, a signal machine in front of the degraded train running path is opened, and a driver drives a train to enter a next concentration area after identifying the signal in front as a green light.
Referring to fig. 7, by the above method, the master OC of the degraded train running path can be smoothly switched to the destination OC, that is, the adjacent OC, and the running path is continuously planned for the degraded train by the adjacent OC. And after the original master control OC receives the planned running path, the original master control OC opens a signal for the train.
The degraded train path handover method provided by the invention provides a stable and reliable handover scheme for handling the degraded train running path among the OC based on communication and state conversion among the OC, so that the degraded train running path can smoothly run to the next OC and continue handling when crossing the OC, the degraded train and the normal train running are not affected each other, and the operation efficiency is improved.
Fig. 5 is a second flow chart of the degraded train path handover method provided by the present invention, as shown in fig. 5, the method includes:
step 400, a first request message is sent to a second OC, wherein the first request message is used for requesting to handover the running path of the degraded train;
step 500, receiving a first response message and a second request message sent by a second OC, wherein the first response message is used for responding to the first request message, and the second request message is used for requesting to execute the operation of handing over the running path of the degraded train;
step 600, handing over the running path of the degraded train, so that the second OC synchronizes the running path of the degraded train, and after the handing over is completed, a second response message is sent to the second OC, wherein the second response message is used for responding to the second request message;
step 700, opening a signal for the degraded train when the updated running path of the degraded train sent by the second OC is received.
The main execution body of the method may be a computer device or a first object controller OC, and the method is executed by the first object controller OC as an example, and the degraded train path handover method provided by the present invention is described in detail below.
Optionally, the present invention provides a degraded train path handover method based On an inter-OC communication based train control system, wherein the related system includes an existing object Controller (Object Controller, OC), a train intelligent monitoring system (INTELLIGENT TRAIN Supervision, ITS) and an On-Board Controller (INTELLIGENT VEHICLE On-Board Controller, IVOC), and IVOC is divided into subsystems: train intelligent Protection system ITP (INTELLIGENT TRAIN Protection, ITP), train intelligent driving system (INTELLIGENT TRAIN Operationn, ITO).
In the train communication system, a train is degraded due to communication failure between the train and a first object controller OC (see fig. 2, OC 1), which plans a running path for each degraded train to ensure safe running of the degraded train in the running path. The train running in the degraded train running path needs to arrive at the adjacent OC (i.e., the second object controller OC, see fig. 2, OC 2), and the degraded train path information needs to be synchronized by the adjacent OC to continue planning the degraded train path in the present OC (i.e., the second object controller OC) for the degraded train. To synchronize the degraded train path information of the first object control OC with the adjacent second object control 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 mode and a state machine conversion mode. The following steps introduce the specific process of command interaction:
the first object controller OC sends a first request message to the second object controller OC, which may be specifically a handover application for downgrading the running path of the train, for the first request message to request handover of the running path of the downgraded train.
After the second object controller OC (adjacent OC) receives the first request message of the first object controller OC (i.e., the master OC), it is checked whether the degraded train is located at the boundary of the master OC, specifically, whether the current end point of the degraded train is located at the boundary point of the master OC and the adjacent OC may be determined, if it is determined that the degraded train is located at the boundary of the master OC, the second object controller OC sends a first response message to the first object controller OC, and simultaneously sends a second request message to the first object controller OC, where the second request message may be specifically a handover execution application for requesting execution of an operation for handing over the running path of the degraded train. The second OC can synchronize the travel path of the degraded train after handing over the travel path of the degraded train.
Referring to fig. 3, the first object controller OC receives a first response message and a second request message sent by the second object controller OC, and after the handover is completed, the second object controller OC sends a second response message to the second object controller OC, and the second response message may be specifically a handover execution application reply, which is used for calculating an extension condition for the degraded train after the second object controller OC receives the second response message in response to the second request message, and continuing to plan a subsequent running path for the degraded train.
After the first object controller OC receives the planned (i.e. updated) running path of the degraded train of the second object controller OC, a signal is opened for the degraded train, specifically, a signal machine in front of the running path of the degraded train is opened, and after the driver recognizes the signal in front as a green light, the driver drives the train to drive into the next concentration area.
According to the degraded train path handing over method provided by the invention, the mode that the train in the existing train control system depends on the manual driving train after being degraded is optimized, the handing over of the running path after the degraded train is realized based on inter-OC communication, the running path of the degraded train is planned, and the line resources of the running path are released after the degraded train exits the running path, which is equivalent to providing virtual blocking control for the degraded train, so that the operation of the degraded train and the normal train is not affected, and the operation efficiency is improved.
Further, in one embodiment, after the first request message is sent to the second OC, the method may further specifically include:
Changing the state of the first OC from an idle state to an initiate waiting state;
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 initiation waiting state to the idle state, and sending the first request message to the second OC again.
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 (adjacent OC), the state of the master OC is changed from the idle state to the wait-for-initiation state, if the first response message is not received within the communication interruption time, the first object controller OC automatically returns to the idle state, and sends the first request message to the second object controller OC again, so as to execute the new path planning.
According to the degraded train path handing over method provided by the invention, the mode that the train is degraded and then depends on a manual driving train in the existing train control system is optimized, the handing over of the running path after the degraded train is realized based on inter-OC communication and state conversion, the running path of the degraded train is planned, and the line resources of the running path are released after the degraded train exits the running path, which is equivalent to providing virtual blocking control for the degraded train, so that the operation of the degraded train and the normal train are not affected, and the operation efficiency is improved.
Further, in one embodiment, after receiving the first response message and the second request message sent by the second OC, the method may further specifically include:
After receiving a first response message sent by the second OC, changing the state of the first OC from an initiation waiting state to a timing waiting state;
After receiving the second request message sent by the second OC, updating the state of the first OC from the timing waiting state to the idle state, and changing the first OC to 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 (adjacent OC) checks whether the degraded train is located at the boundary of the master OC, and if it is determined that the degraded train is located at the boundary of the master OC, the second object controller OC transmits a first response message to the first object controller OC, and simultaneously transmits a second request message to the first object controller OC, and changes the state of the second object controller OC from the idle state to the waiting state for the last reply.
After the first object controller OC receives the first response message, changing the state of the first object controller OC from the initial waiting state to the timing waiting state, after the first object controller OC receives the second request message, changing the state of the first object controller OC from the timing waiting state to the idle state, and sending a second response message to the second object controller OC, after the second object controller OC receives the second response message, changing the state of the second controller OC from the waiting last reply state to the idle state, and changing the second controller OC to the first object controller OC (namely, the master control OC), and calculating the extension condition for the degraded train in the idle state.
After the second object controller OC is updated to the master OC, the planning of the travel path for the degraded train is continued. After the original first object controller OC receives the degraded train running path after the adjacent OC planning is completed, a signal machine in front of the degraded train running path is opened, and a driver drives a train to enter a next concentration area after identifying the signal in front as a green light.
Referring to fig. 7, by the above method, the master OC of the degraded train running path can smoothly switch to the destination OC, that is, the adjacent OC, and the adjacent OC continues to plan the running path for the degraded train (i.e., update the degraded train path). And after the original master control OC receives the planned running path, the original master control OC opens a signal for the train.
