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 consist retracing method of the present invention is described below in conjunction with fig. 1-3. The embodiment is a train turning-back method of a marshalling train provided in a mode of turning-back route control and resource management on a train control system based on vehicle-to-vehicle communication. The main execution body in this embodiment is a train composition folding device, and the device may be an interlock system or an Object control system in the interlock system, such as a TIOC (traffic Intelligent Object controller) system, which is not specifically limited in this embodiment.
The following describes a train set-up folding method in this embodiment, taking an implementation subject as a TIOC system as an example.
As shown in fig. 1, one of the flow diagrams of the train composition folding method provided in the present application is specifically that the method includes the following steps:
it should be noted that the current train may be a front train in the virtual formation, a rear train or a non-formation train, and may be determined specifically according to a service requirement.
The request for the route-returning resource is used to request for applying for a route-returning resource, and specifically may be sent by an IVOC (Intelligent Vehicle On-Board Controller) On a Train about to enter the route-returning resource, or may be sent by an ITS (Intelligent Train Supervision) system that intelligently monitors the Train when monitoring that the Train is about to enter the route-returning resource, which is not specifically limited in this embodiment.
Optionally, the IVOC and the ITS are monitored in real time to respond when receiving a retrace entry resource request of the current train sent by the IVOC and/or the ITS, and perform retrace entry resource allocation for the current train.
102, under the condition that the current train is determined to be a virtual train set, determining whether the target train is a front train of the current train in the virtual train set where the current train is located according to the train set information of the current train and the train information of the target train with the retracing route resources distributed in the retracing route;
the virtual marshalling technology realizes cooperative control of the running speed and the distance interval of multiple trains through wireless communication, is coupled into a coordinated logic whole under the condition of no physical connection, and schedules and manages the train group as a logic unit.
The virtual marshalling at least comprises front and rear vehicles which run on the same running line along the same running direction, wherein the front vehicle is a train which is arranged in front in the running direction; the rear train is a train which is sequenced backwards in the running direction.
The formation information includes at least a formation state, a pre-formation front-car/post-formation car relationship (the car is a front car or a rear car in the virtual formation), and a train number of the formation with the train; the marshalling state comprises state information such as marshalling establishment, marshalling operation and marshalling decompiling.
It should be noted that two trains in vehicle-to-vehicle communication mutually transmit a train formation state, and periodically transmit the respective train formation state, the relationship between the train before and after the train formation, and train information such as a serial number or operation information, etc. formed with the train formation state to the TIOC system, that is, the TIOC system stores the train formation information of each virtual train formation in advance.
Optionally, after receiving the request for the reentry route resource, the TIOC system allocates the reentry route resource according to a first-come-first-obtained principle.
Optionally, when the retrace entry resource request of the current train is acquired, the current train may be searched in the formation information sent by the virtual formation train according to the train number in the retrace entry resource request and according to the train number, and whether the current train is the virtual formation train is determined according to a search result.
In the case where the current train is not found, it is determined that the current train is not a virtual consist train. At this time, if it is judged that a target train in the retrace route has the retrace route resource allocation condition and the retrace route resource is allocated, the retrace route resource is not allocated to the current train.
And under the condition that the current train is found, determining the current train as a virtual marshalling train. Under the condition that the train information of the target train which is distributed with the retracing route resources in the retracing route is matched with the train information of the front train in the formation information of the current train, the target train is determined to be the front train of the current train, namely the current train which applies for the retracing route resources and the target train which is distributed with the retracing route resources have the relationship between the front train and the rear train of the virtual formation, namely the two trains are trains running in the same formation fleet.
103, under the condition that the target train is determined to be the front train of the current train, allocating a retrace entry resource to the current train according to the retrace entry resource request and the formation information.
Alternatively, when it is determined that the target train is a preceding train of the current train, route resource allocation is performed on the current train in a formation form according to the retrace route resource request and the formation information, that is, in the same retrace route, the current train and the target train can perform a retrace operation simultaneously in the same retrace route in a form of a virtual formation.
In this embodiment, after receiving a request for a turnaround route resource of a current train through a TIOC system, if a target train is determined to be a lead train of the current train according to formation information of the current train and train information of the target train to which the turnaround route resource is allocated in a turnaround route, in a virtual formation where the current train is located, the turnaround route resource is allocated to the current train according to the request for the turnaround route resource and the formation information, so that the current train and the target train can perform a turnaround operation in the same turnaround route in a virtual formation manner, thereby improving efficiency of train turnaround operation, relieving line pressure, and improving transport capacity of the turnaround line.
In some embodiments, said allocating a retrace entry resource to the current train according to the retrace entry resource request and the consist information in step 103 comprises:
under the condition that the retracing access resource request comprises a retracing access resource request, verifying whether the current train meets the allocation condition of the retracing access resource according to the occupation information of the retracing access and the retracing access resource request;
and under the condition that the current train meets the allocation condition of the folded-in access resources, allocating the retraced access resources for the current train according to the marshalling information and the access information of the folded-in access in the folded-in access resource request.
The folding-back inlet route comprises a folding-in inlet route and a folding-out inlet route, the folding-in inlet route and the folding-out inlet route both comprise a plurality of axle counting sections, and the specific number can be set according to business requirements. Taking fig. 2 as an example, the routes S2 to S3 are the folding routes in the folding routes, the folding routes include four axle counting sections, AC2, AC4, AC5 and AC7, respectively, and the routes X1 to X2 are the folding routes in the folding routes, and include two axle counting sections, AC6 and AC8, respectively.
Accordingly, the retrace entry resource request includes a retrace entry resource request and a retrace exit entry resource request.
The route resource allocation condition includes that the occupation information of the folded route applied by the train is normally occupied, and the train applying the folded route resource has a route resource allocation authority, which is not specifically limited in this embodiment.
Optionally, when the retrace entry resource request includes a retrace entry resource request, the step of allocating retrace entry resources in step 103 specifically includes:
firstly, determining whether the folded-in access path has abnormal occupation or not according to the occupation information of the folded-back access path; determining whether the current train has the access resource allocation authority or not according to the retracing access resource request, and determining that the current train meets the retracing access resource allocation condition under the condition that the current train and the retracing access resource request meet the access resource allocation authority; and under the condition that either one of the two conditions is not satisfied, determining that the current train does not satisfy the folded access resource allocation condition, namely that the current train does not have the access condition.
And under the condition that the current train meets the resource allocation condition of the folding-in route, generating a folding-back resource allocation instruction according to the marshalling information and the route information of the folding-in route in the resource request of the folding-in route, and allocating folding-back route resources corresponding to the folding-in route for the current train.
In this embodiment, whether the current train meets the resource allocation condition of the folded-in route is verified according to the occupation information of the folded-back route and the resource request of the folded-back route, so that the folded-back route resource is allocated to the current train according to the marshalling information and the route information of the folded-in route in the resource request of the folded-in route under the condition that the current train meets the resource allocation condition of the folded-in route, and thus the accurate allocation of the route resource is ensured, so that the current train and the target train can be in a virtual marshalling form, and the safe folding-back operation is simultaneously performed in the same folded-back route, thereby improving the safety and efficiency of the train folding-back operation, relieving the pressure of the route, and improving the transport capacity of the folded-back route.
In some embodiments, the allocating the retracing route resource to the current train according to the formation information and the route information of the retracing route in the retracing route resource request includes:
determining an axle counting section of the folded access according to the access information of the folded access;
acquiring the pressure occupying sections folded into the access road according to the occupation information of each axle counting section, and determining that the pressure occupying sections are in a normal pressure occupying state;
under the condition that the pressure occupying section is determined to be in a normal pressure occupying state, determining whether a train occupying the pressure occupying section is a front train of the current train or not according to the grouping information;
and under the condition that the train occupying the pressure zone is determined to be the front train of the current train, distributing the retrace route resource for the current train according to the route information of the pressure zone.
The route information of the folded route at least comprises information of each section in the folded route.
Alternatively, since the marshalled vehicles enter the turn-back route closure start semaphore, although the front and rear vehicles are marshalled as a whole on a logical level, but there are two trains on an actual physical level, the turn-back route resource is allocated to the current train in step 103, and the first problem to be solved is the timing of the two vehicles entering the route closure semaphore. In the existing mode of route control of turning back, as long as the interior district section of route has the occupation of pressure, the semaphore will close, will exist the front truck when entering the semaphore and has closed, the circumstances that the back car rushed the red light and got into. Therefore, in order to solve this problem, the present embodiment does not directly turn off the traffic signal when the train enters the route before the formation, but turns off the traffic signal when the train enters the route after the formation, by changing the existing route traffic signal control logic, thereby ensuring that the current train and the target train can perform the retracing operation on the retracing route in a virtual formation manner. Therefore, the step of allocating the retracing route resource to the current train in step 103 specifically includes:
determining an axle counting section contained in the folded access according to the access information of the folded access; and determining the pressure occupying zone in the pressure occupying state in the axle counting zone according to the occupation information of each axle counting zone, and judging whether the pressure occupying zone is in normal pressure occupying or not according to the occupation information.
And under the condition that the pressure occupying section is abnormal in pressure occupying, the signal machine on the folded access road should be immediately closed, the access road resource allocation authority of the current train is recovered, and the current train is not allowed to enter the folded access road.
And under the condition that the occupied pressure zone is normal occupied pressure, matching the train information of the front train in the formation information of the current train with the train information for determining the occupied pressure zone so as to determine whether the train occupying the occupied pressure zone is the front train or the non-formation train of the current train.
And under the condition that the train occupying the pressure zone is determined to be a non-marshalling train, the signal machine on the folding-in access road should be immediately closed, the access road resource allocation authority of the current train is recovered, and the current train is not allowed to enter the folding-in access road.
And under the condition that the train occupying the pressure zone is determined to be the front train of the current train, starting a signal machine on the folding access road, and distributing folding access road resources for the current train according to the access information of the pressure zone so as to allow the current train to enter the folding access road.
In this embodiment, according to the formation information and the route information of the folded route in the folded route resource request, it can be ensured that when a certain section in the folded route is occupied by a pre-formation train of the current train, the folded route resource can also be allocated to the current train, so as to ensure that the pre-formation train and the target train can be in a virtual formation form, and the safe folding operation can be simultaneously performed in the same folded route, thereby improving the safety and efficiency of the train folding operation, relieving the line pressure, and improving the transport capacity of the folded route.
In some embodiments, the allocating a retrace entry resource to the current train according to the retrace entry resource request and the consist information in step 103 includes:
under the condition that the retracing entry resource request comprises a retracing entry resource request, determining whether the current train drives into a retracing parking area or not according to the running state of the current train in the formation information;
under the condition that the current train is determined to drive into the turn-back parking area, controlling a signal machine on a turn-back approach in the turn-back approach to be switched to an open state;
under the condition that the door of the current train is determined to be switched to the open state according to the door opening and closing state of the current train in the marshalling information, controlling the annunciator to be switched to the closed state;
and controlling the annunciator to be switched to an open state under the condition that the door of the current train is determined to be switched to a closed state according to the door opening and closing state.
Optionally, if the folded parking area is a triggering section of the folded entry route, when the train completely enters the folded parking area but the door opening and closing operation is not performed yet, the signal machine of the folded entry route triggers the folded entry route to handle, and at this time, when the train performs the door opening and closing operation again, the folded entry route does not satisfy the condition that the signal machine is opened because the platform door is opened, the train cannot obtain the withdrawn entry route resource, and the train cannot enter the folded entry route.
In order to solve the above problem, in the embodiment, the TIOC is configured with a function of automatically re-opening the traffic signal, that is, when the access signal is closed due to the opening of the platform door, the TIOC automatically checks the access condition and opens the access signal after the platform door is closed. And allocating access resources for front and rear trains of the marshalling after receiving an ITS or access resource application command of the trains, and allowing the trains to enter and fold out of the access.
Optionally, when the retrace entry resource request includes a retrace entry resource request, the step of allocating retrace entry resources in step 103 specifically includes:
acquiring the running state of the current train from the marshalling information, and determining whether the current train drives into a turn-back parking area according to the running state information;
and under the condition that the current train enters the turn-back parking area, controlling a signal machine on a turn-back approach in the turn-back approach to be switched to an open state. Under the condition that the door of the current train is determined to be switched to the open state according to the door opening and closing state of the current train obtained from the marshalling information, the signal machine is controlled to be switched to the closed state;
and then according to the door opening and closing state, under the condition that the door of the current train is determined to be switched to the closing state, the annunciator is controlled to be switched to the opening state again, so that the purpose of accurately distributing the retracing route resources for the current train is achieved, the safe driving is ensured, the marshalling train can simultaneously carry out the safe retracing operation in the same retracing route, and the safety and the efficiency of the train retracing operation are improved.
In some embodiments, the method further comprises:
under the condition of receiving the resource release request of the current train, determining whether the train which applies for the route resource release in the retracing route is the front train of the current train or not according to the formation information of the current train;
and under the condition that the train applying for the release of the access resources is determined to be the front train of the current train, the access unlocking is handled for the current train according to the grouping information.
The resource release request is used for requesting release of the route resource so as to realize route unlocking.
Optionally, in the case of receiving a resource release request sent by the IVOC and/or the ITS of the current train, obtaining train information for which route resource release has been applied in the retracing route, and matching the train information with the preceding train information in the formation information of the current train, and in the case of matching the train information and the preceding train information, determining that the train for which route resource release has been applied is the preceding train of the current train.
