Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a method, device and system for turning back a marshaled train. Background Art

[0002] With the rapid development of rail transit networking, the contradiction between the transportation capacity (referred to as transport capacity) of existing rail transit lines and demand has become increasingly prominent. How to improve the transport capacity of rail transit lines has become one of the primary research focuses at present.

[0003] In a single-route station type, trains usually track and run in the section, turn around at the terminal station, and then track and run in the section in the reverse direction. Trains must maintain a certain distance in time and space on the line, so they depart at a certain time interval at the terminal station and track and run at a certain time interval in the section. The reversal process after the terminal station includes the entry stage, the entry reversal line stage, the exit reversal line stage, and the exit stage. Among them, operations such as trains entering and exiting stations, stopping at stations to drop off passengers, entering and exiting reversal lines, and stopping at stations to pick up passengers are included. In addition, the position of the train on the section line at the entry and exit ends should also be considered during the entry and exit process. These factors all affect the line's reversal capacity.

[0004] However, currently, both the train control system with vehicle-to-vehicle communication and the traditional CBTC (Communication Based Train Control) system only allow one vehicle to enter the same reversing route for reversing operations. The ground control center sends reversing information to a single train according to the train number of the single train. However, when controlling the reversal of multiple vehicles, for multiple vehicles with the same route, the ground control center controls each train in turn, resulting in low train driving efficiency and poor transportation capacity of the rail transit line. Summary of the invention

[0005] The present invention provides a method, device and system for turning back a marshaled train, so as to solve the defect in the prior art that only one vehicle is allowed to enter the same turning back route for turning back operation, resulting in low train driving efficiency and poor transportation capacity of rail transit lines, thereby improving train driving efficiency and line transportation capacity.

[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Combine the following Figure 1-Figure 3Describe the marshaling train reversal method of the present invention. This embodiment is a marshaling train reversal method provided on a train control system based on vehicle-to-vehicle communication, based on reversal route control, and under a resource management mode. The execution subject in this embodiment is a marshaling train reversal device, which can be an interlocking system or an object control system in an interlocking system, such as a TIOC (TCT Intelligent Object Controller) system, which is not specifically limited in this embodiment.

[0051] The following describes the train turnaround method in this embodiment by taking the TIOC system as an example.

[0052] like Figure 1 As shown, it is one of the flow diagrams of the marshaling train return method provided by the present application, and the method specifically includes the following steps:

[0053] Step 101, receiving a return route resource request of the current train;

[0054] It should be noted that the current train can be the front train or the rear train or a non-marshaling train in the virtual marshaling, which can be determined according to business needs.

[0055] The reversing route resource request is used to request the reversing route resources. Specifically, it may be sent by the IVOC (Intelligent Vehicle On-Board Controller) on the train that is about to enter the reversing route, or it may be sent by the ITS (Intelligent Train Supervision) that performs intelligent monitoring of the train when it detects that the train is about to enter the reversing route. This embodiment does not make any specific limitation on this.

[0056] Optionally, IVOC and ITS are monitored in real time to respond upon receiving a reversing route resource request for the current train sent by IVOC and / or ITS, and to allocate reversing route resources for the current train.

[0057] Step 102, when it is determined that the current train is a virtual marshaling train, according to the marshaling information of the current train and the train information of the target train to which the reversing route resources are allocated in the reversing route, in the virtual marshaling where the current train is located, determining whether the target train is the preceding train of the current train;

[0058] Among them, virtual marshalling technology realizes collaborative control of the running speeds and distance intervals of multiple trains through wireless communication, couples them into a coordinated logical whole without physical connection, and dispatches and manages the train group as a logical unit. Currently, this technology has been applied in fully automatic operation lines of urban rail transit.

[0059] The virtual formation includes at least the front and rear cars traveling on the same route and in the same direction, wherein the front car is the train that is ranked ahead in the direction of travel; and the rear car is the train that is ranked behind in the direction of travel.

[0060] The marshaling information includes at least the marshaling status, the relationship between the front and rear cars of the marshaling (whether the car is the front or rear car in the virtual marshaling), and the train number of the train marshaling; the marshaling status includes status information such as marshaling establishment, marshaling operation and marshaling disassembly.

[0061] It should be noted that the two trains communicating with each other transmit their marshaling status to each other, and periodically send their respective marshaling status, the relationship between the front and rear trains in the marshaling, and the train information marshaled with them, such as the number or operation information, to the TIOC system. That is, the TIOC system pre-stores the marshaling information of each virtual marshaling train.

[0062] Optionally, after receiving the reentry route resource request, the TIOC system allocates the reentry route resources on a first-come, first-served basis.

[0063] Optionally, when the reversing route resource request for the current train is obtained, the current train can be searched in the marshaling information sent by the virtual marshaling train according to the train number in the reversing route resource request and the train number, and based on the search result, it is determined whether the current train is a virtual marshaling train.

[0064] In the case where the current train is not searched, it is determined that the current train is not a virtual marshaling train. At this time, if it is determined that there is a target train in the reversing route that has the reversing route resource allocation conditions and has been allocated reversing route resources, the reversing route resources are not allocated to the current train.

[0065] When the current train is found, the current train is determined to be a virtual marshaling train. When it is determined that the train information of the target train that has been allocated with the reversing route resources matches the train information of the preceding train in the marshaling information of the current train, the target train is determined to be the preceding train of the current train, that is, the current train that has applied for the reversing route resources and the target train that has been allocated with the reversing route resources have a virtual marshaling front and rear train relationship, that is, the two trains are trains running in the same marshaling fleet.

[0066] Step 103, when it is determined that the target train is the preceding train of the current train, a reversing route resource is allocated to the current train according to the reversing route resource request and the formation information.

[0067] Optionally, when it is determined that the target train is the preceding train of the current train, route resources are allocated to the current train in the form of marshaling according to the reversing route resource request and the marshaling information, that is, in the same reversing route, the current train and the target train can perform reversing operations simultaneously in the same reversing route in the form of virtual marshaling.

[0068] The present embodiment provides a method for reversing a marshaled train. After receiving a reversing route resource request of a current train through the TIOC system, if, based on the marshaling information of the current train and the train information of a target train with reversing route resources allocated in the reversing route, in a virtual marshaling where the current train is located, it is determined that the target train is the preceding train of the current train, reversing route resources are allocated to the current train based on the reversing route resource request and the marshaling information, so that the current train and the target train can perform reversing operations simultaneously in the same reversing route in the form of a virtual marshaling, thereby improving the efficiency of the train reversing operation, alleviating line pressure, and improving the transportation capacity of the reversing line.

[0069] In some embodiments, the allocating of the turnaround route resource to the current train according to the turnaround route resource request and the marshaling information in step 103 includes:

[0070] In the case where the return route resource request includes a turn-in route resource request, verifying whether the current train meets the turn-in route resource allocation condition according to the return route occupancy information and the return route resource request;

[0071] When it is determined that the current train meets the conditions for allocating the turn-in route resources, the turn-in route resources are allocated to the current train according to the formation information and the route information of the turn-in route in the turn-in route resource request.

[0072] The return route includes the turn-in route and the turn-out route. Both the turn-in route and the turn-out route contain multiple axle counting sections, and the specific number can be set according to business needs. Figure 2 For example, the S2 to S3 approach is the turn-in approach in the turn-around approach, which includes four axle counting sections, namely AC2, AC4, AC5 and AC7. The X1 to X2 is the turn-out approach in the turn-around approach, which includes two axle counting sections, namely AC6 and AC8.

[0073] Accordingly, the return route resource request includes an incoming route resource request and an outgoing route resource request.

[0074] The route resource allocation conditions include that the occupancy information of the turn-in route applied for by the train is normal occupancy, and the train applying for the return route resource has the route resource allocation authority, etc. This embodiment does not make specific restrictions on this.

[0075] Optionally, in the case where the return route resource request includes a return route resource request, the step of allocating the return route resources in step 103 specifically includes:

[0076] First, based on the occupancy information of the return route, determine whether there is abnormal occupancy in the return route; and based on the return route resource request, determine whether the current train has the route resource allocation authority. When both are met, it is determined that the current train meets the conditions for allocating the return route resources; when either of the two is not met, it is determined that the current train does not meet the conditions for allocating the return route resources, that is, the current train does not have the conditions to enter the route.

[0077] When the current train meets the conditions for allocating the turn-in route resources, a turn-back resource allocation instruction is generated based on the marshaling information and the turn-in route information in the turn-in route resource request to allocate the turn-back route resources corresponding to the turn-in route to the current train.

[0078] In this embodiment, based on the occupancy information of the reversing route and the reversing route resource request, it is verified whether the current train meets the reversing route resource allocation conditions. If the current train meets the reversing route resource allocation conditions, reversing route resources are allocated to the current train based on the marshaling information and the route information of the reversing route in the reversing route resource request, thereby ensuring accurate allocation of route resources, so that the current train and the target train can perform safe reversing operations simultaneously in the same reversing route in the form of virtual marshaling, thereby improving the safety and efficiency of the train reversing operation, alleviating line pressure, and improving the transportation capacity of the reversing line.

[0079] In some embodiments, allocating the return route resource to the current train according to the marshaling information and the route information of the return route in the return route resource request includes:

[0080] Determining an axle counting section of the fold-in route according to route information of the fold-in route;

[0081] According to the occupation information of each axle counting section, the occupied section in the folded-in route is obtained, and it is determined whether the occupied section is in a normal occupied state;

[0082] When it is determined that the occupied section is in a normal occupied state, determining whether the train occupying the occupied section is the preceding train of the current train according to the marshaling information;

[0083] When it is determined that the train occupying the occupied section is the preceding train of the current train, the return route resources are allocated to the current train according to the route information of the occupied section.

[0084] The route information of the folded-in route at least includes information of each section in the folded-in route.

[0085] Optionally, since the marshaling vehicle enters the reversing route and closes the starting signal, although the front and rear vehicles of the marshaling are regarded as a whole at the logical level, they are still two trains at the actual physical level. Therefore, in step 103, the reversing route resources are allocated to the current train. The first problem to be solved is the timing of the two vehicles entering the route to close the signal. In the existing reversing route control method, as long as the inner section of the route is occupied, the signal will be closed. There will be a situation where the signal is already closed when the front vehicle enters, and the rear vehicle enters the route against a red light. Therefore, in response to this problem, this embodiment changes the existing route signal control logic. When the front vehicle of the marshaling enters the route, the signal is not directly closed, and the signal is closed only when the rear vehicle enters, thereby ensuring that the current train and the target train can perform reversing operations in the reversing route at the same time in the form of virtual marshaling. Therefore, the step of allocating the reversing route resources to the current train in step 103 specifically includes:

[0086] According to the route information of the turning-in route, the axle counting sections included in the turning-in route are determined; and according to the occupancy information of each axle counting section, the occupied sections in the axle counting sections are determined, and according to the occupancy information, it is judged whether the occupied sections are normally occupied.

[0087] In the case of abnormal occupation in the occupied section, the signal on the turn-in route should be closed immediately, the route resource allocation authority of the current train should be withdrawn, and the current train is not allowed to enter the turn-in route.

[0088] When the occupied section is normally occupied, the train information of the preceding car in the marshaling information of the current train is matched with the train information determined to occupy the occupied section to determine whether the train occupying the occupied section is the preceding car of the current train or a non-marshaling train.

[0089] When it is determined that the train occupying the occupied section is a non-marshaled train, the signal on the turn-in route should be closed immediately, the route resource allocation authority of the current train should be withdrawn, and the current train is not allowed to enter the turn-in route.

[0090] When it is determined that the train occupying the occupied section is the preceding train of the current train, the signal on the turn-in route should be turned on, and according to the route information of the occupied section, the turn-in route resources should be allocated to the current train to allow the current train to enter the turn-in route.

[0091] In this embodiment, based on the marshaling information and the route information of the turn-around route in the turn-around route resource request, it can be ensured that when a section in the turn-around route is occupied by the preceding train of the current train, the turn-around route resources can also be allocated to the current train, ensuring that the preceding train and the target train can perform safe turn-around operations simultaneously in the same turn-around route in the form of virtual marshaling, thereby improving the safety and efficiency of the train turn-around operation, alleviating line pressure, and improving the transportation capacity of the turn-around line.

[0092] In some embodiments, the allocating of the turnaround route resource to the current train according to the turnaround route resource request and the marshaling information in step 103 includes:

[0093] In the case where the return route resource request includes a return route resource request, determining whether the current train enters a return parking area according to the running state of the current train in the formation information;

[0094] When it is determined that the current train enters the turnaround parking area, the signal on the turnaround route is controlled to be switched to an on state;

[0095] When it is determined that the doors of the current train are switched to an open state according to the door opening and closing state of the current train in the marshaling information, the signal is controlled to be switched to a closed state;

[0096] When it is determined according to the door opening and closing state that the door of the current train is switched to the closed state, the signal is controlled to switch to the open state.

[0097] Optionally, if the turnaround parking area is the triggering section of the turn-out route, when the train completely enters the turnaround parking area but has not yet performed the door opening and closing operation, the signal of the turn-out route will first trigger the turn-out route processing. At this time, when the train performs the door opening and closing operation again, the turn-out route will not meet the signal opening conditions because the platform door is open. The train cannot obtain the exit route resources, and then the train cannot enter the turn-out route.

[0098] In order to solve the above problem, this embodiment configures the function of automatic signal reopening in TIOC, that is, when the approach signal is closed due to the opening of the platform door, after the platform door is closed, TIOC automatically checks the approach conditions and opens the approach signal. After receiving the approach resource application command from ITS or train, it allocates approach resources to the front and rear vehicles of the marshaling group, allowing the train to enter and exit the approach.

[0099] Optionally, in the case where the return route resource request includes the outward route resource request, the step of allocating the return route resources in step 103 specifically includes:

[0100] Obtain the running status of the current train from the marshaling information, and determine whether the current train enters the turnaround parking area based on the running status information;

[0101] When it is determined that the current train enters the turnaround parking area, the signal on the turnaround route is controlled to switch to the open state. When it is determined that the door of the current train is switched to the open state according to the door opening and closing state of the current train obtained from the marshaling information, the signal is controlled to switch to the closed state;

[0102] Then, based on the door opening and closing status, when it is determined that the door of the current train is switched to the closed state, the signal is controlled to switch back to the open state, so as to accurately allocate the reversing route resources for the current train, ensure driving safety, and ensure that the marshalled train can perform safe reversing operations in the same reversing route at the same time, thereby improving the safety and efficiency of the train reversing operation.

[0103] In some embodiments, the method further comprises:

[0104] In the case of receiving a resource release request of the current train, determining whether the train that has applied for route resource release in the reversing route is the preceding train of the current train according to the marshaling information of the current train;

[0105] When it is determined that the train that has applied for route resource release is the preceding train of the current train, route unlocking is performed for the current train according to the formation information.

[0106] Among them, the resource release request is used to request the release of route resources to achieve route unlocking.

[0107] Optionally, when receiving a resource release request sent by IVOC and / or ITS of the current train, the train information that has applied for route resource release in the reversing route is obtained, and it is matched with the information of the preceding train in the marshaling information of the current train. When the two match, it is determined that the train that has applied for route resource release is the preceding train of the current train. That is, when the TIOC system simultaneously receives resource release requests sent by the preceding train and the following train in the virtual marshaling in the section within the reversing route, it handles route unlocking for the current train according to the marshaling information, so as to logically treat the two trains in the marshaling as a whole, allocate route resources to the two trains in the marshaling, and thus improve the efficiency of the train reversing operation.

[0108] In some embodiments, the method further comprises:

[0109] When it is determined that the current train is the front train in the virtual marshaling based on the marshaling information of the current train, if it is judged that the train that has applied for the release of route resources has driven out of the target section required to be occupied by the current train, the route unlocking is processed for the current train based on the occupancy information of the target section required to be occupied by the current train, as well as the occupancy information of the section in front and the occupancy information of the section behind the target section.

[0110] Optionally, when the information of the train that has applied for the release of route resources does not match the information of the preceding vehicle in the marshaling information of the current train, the train that has applied for the release of route resources is determined to be a non-marshaling train of the current train. If the current train is determined to be the preceding vehicle in a virtual marshaling according to the marshaling information of the current train, and the train that has applied for the release of route resources has already left the reversing route, the route is unlocked for the current train using a three-point inspection logic based on the occupancy information of the target section that the current train needs to occupy, as well as the occupancy information of the section in front of the target section and the occupancy information of the section behind, thereby ensuring the accuracy of the route unlocking and improving the safety of the train reversing operation.

[0111] In some embodiments, the step 101 of receiving the turnaround route resource request of the current train includes:

[0112] receiving the reversing route resource request sent by the intelligent train monitoring system ITS according to the train operation plan when monitoring that the current train enters the first target position at a first preset distance from the reversing route;

[0113] And / or, receiving the turnaround route resource request sent according to the train operation plan when the current train enters a second target position at a second preset distance from the turnaround route.

[0114] The first preset distance may be the same as or different from the second preset distance, such as the first preset distance is greater than the second preset distance.

[0115] Optionally, when the current train enters the first target position at the first preset distance from the return route, the ITS may apply to the TIOC for route resources for each train in the virtual formation where the current train is located according to the train operation plan;

[0116] And / or when the current train enters the second target position at a second preset distance from the return route, it autonomously applies to the TIOC for route resources according to the train operation plan.

[0117] In this embodiment, the reversing route resource request of the current train can be received in a variety of ways, thereby ensuring the stability and reliability of the reversing route resource request and improving the accuracy of the train reversal.

[0118] like Figure 3 As shown, this embodiment provides a second flow chart of a method for turning back a marshaled train, which specifically includes the following steps:

[0119] Step 301: The train or ITS applies for fold-in route resources for the train;

[0120] Step 302, TIOC allocates turn-in route resources for the train, and the train enters the turn-in route;

[0121] Step 303, TIOC unlocks the train's entry route;

[0122] Step 304, the train turns back and changes ends;

[0123] Step 305: The train or ITS applies for route resources for the train;

[0124] Step 306: TIOC allocates outbound route resources to the train, and the train drives out of the outbound route.

[0125] In summary, since one of the important ways to improve the transportation capacity of a line is to allow multiple cars to track and run on the line in the form of marshaling, and the reversing capacity has always been a restrictive factor hindering the tracking and operation of multiple cars, and the train reversing process is a key factor affecting the train reversing capacity, therefore, this embodiment provides a marshaling train reversing method based on the vehicle-to-vehicle communication mode, optimizes the marshaling train reversing process, and realizes the marshaling train reversing operation function through route management and resource allocation, which is of great significance to improving the marshaling running train capacity, alleviating line pressure, and improving line transportation capacity.

[0127] like Figure 4 As shown, this embodiment provides a marshaling train return device 40, which includes a receiving module 401, a judging module 402 and an allocating module 403, wherein:

[0128] The receiving module 401 is used to receive the return route resource request of the current train;

[0130] The allocation module 403 is used to allocate the reversing route resources to the current train according to the reversing route resource request and the formation information when it is determined that the target train is the preceding train of the current train.

[0131] The train reversing device provided in this embodiment receives a reversing route resource request from the current train through the TIOC system. If, based on the marshaling information of the current train and the train information of the target train with reversing route resources allocated in the reversing route, in the virtual marshaling where the current train is located, it is determined that the target train is the preceding train of the current train, reversing route resources are allocated to the current train based on the reversing route resource request and the marshaling information, so that the current train and the target train can perform reversing operations simultaneously in the same reversing route in the form of virtual marshaling, thereby improving the efficiency of the train reversing operation, alleviating line pressure, and improving the transportation capacity of the reversing line.

[0132] In some embodiments, the allocation module 403 is specifically configured to:

[0133] In the case where the return route resource request includes a turn-in route resource request, verifying whether the current train meets the turn-in route resource allocation condition according to the return route occupancy information and the return route resource request;

[0138] When it is determined that the occupied section is in a normal occupied state, determining whether the train occupying the occupied section is the preceding train of the current train according to the marshaling information;

[0139] When it is determined that the train occupying the occupied section is the preceding train of the current train, the return route resources are allocated to the current train according to the route information of the occupied section.

[0140] In some embodiments, the allocation module 403 is further configured to:

[0141] In the case where the return route resource request includes a return route resource request, determining whether the current train enters a return parking area according to the running state of the current train in the formation information;

[0142] When it is determined that the current train enters the turnaround parking area, the signal on the turnaround route is controlled to be switched to an on state;

[0143] When it is determined that the doors of the current train are switched to an open state according to the door opening and closing state of the current train in the marshaling information, the signal is controlled to be switched to a closed state;

[0144] When it is determined according to the door opening and closing state that the door of the current train is switched to the closed state, the signal is controlled to switch to the open state.

[0145] In some embodiments, an access unlocking module is further included, which is specifically used to:

[0146] In the case of receiving a resource release request of the current train, determining whether the train that has applied for route resource release in the reversing route is the preceding train of the current train according to the marshaling information of the current train;

[0147] When it is determined that the train that has applied for route resource release is the preceding train of the current train, route unlocking is performed for the current train according to the formation information.

[0148] In some embodiments, the access unlocking module is further configured to:

[0149] When it is determined that the current train is the front train in the virtual marshaling based on the marshaling information of the current train, if it is judged that the train that has applied for the release of route resources has left the reversing route, the route unlocking is processed for the current train based on the occupancy information of the target section required to be occupied by the current train, as well as the occupancy information of the section in front of the target section and the occupancy information of the section behind.

[0150] In some embodiments, the receiving module is specifically configured to:

[0151] receiving the reversing route resource request sent by the intelligent train monitoring system ITS according to the train operation plan when monitoring that the current train enters the first target position at a first preset distance from the reversing route;

[0152] And / or, receiving the turnaround route resource request sent according to the train operation plan when the current train enters a second target position at a second preset distance from the turnaround route.
