Description

Technical Field

[0001] The present invention relates to a train signal control system, and in particular to a route control method, equipment and medium taking a train as a control object. Background Art

[0002] In the urban rail transit train control system, the train's running path is realized through the route, which is generally controlled by the interlocking system, and then the train operation is controlled by the train control system. The division and control of the interlocking route is generally based on the signal as the control object, and is designed in a way that a route is formed between every two signal machines. However, according to actual operation needs, the existing control method has the following problems:

[0003] 1. The train route is based on signal lights, and the number of signal lights directly affects the scope of the route. If the route scope is too large, the flexibility of scheduling will be affected. If the route scope is small, the number of signal lights and axles that need to be arranged will increase, increasing construction investment.

[0004] 2. For a signal-based route, after it is established and used by a train, it is not possible to flexibly cancel the route assigned to the train. The route can only be released after the train has completely left the route, which is not conducive to flexible organization of operations.

[0005] 3. For yards with many turnout areas, a separate pull-out line needs to be set up for train switching operations within the yard, and only one train can be switched at a time, which increases investment and affects the efficiency of the yard's switching operations.

[0006] After searching, Chinese Patent Publication No. CN105539526A discloses a rail transit train route control method, which specifically discloses that the rail transit train route process is divided into a route locking stage and an open signal stage; when handling the rail transit train route, the route locking condition is first checked, and if the route locking condition is met, the specified route is locked; after the route is locked, it is determined whether the open signal condition is met, if it is met, the signal is opened, and if not, the signal is opened after the signal opening condition is met; if the locked route condition is not met, the route handling fails, but the existing patent handles the route between two signal machines with the signal machine as the object, and whether the idleness of the track section is checked when the route is established, so the above-mentioned defects will also exist. How to solve the inflexible route control in urban rail transit lines has become a technical problem that needs to be solved. Summary of the invention

[0007] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a route control method, equipment and medium with trains as the control object, which saves construction investment, is flexible in operation and improves efficiency.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] According to a first aspect of the present invention, there is provided a route control method with a train as the control object, which divides the route by axle counting sections, establishes the route with the train as the object, sets the route for the train at any point, and realizes the train's reversal at any point on the line.

[0010] As a preferred technical solution, the method configures the traffic light as needed, but the traffic light only serves as a driving permit in the backup mode.

[0011] As a preferred technical solution, the route is divided by axle counting sections as follows:

[0012] According to the scale of the line, the line is divided into several axle counting sections as the smallest unit of the route;

[0013] Each train route consists of one section or several sections and can be flexibly configured.

[0014] As a preferred technical solution, the starting point of each train route is the section where the train is located, and the end point of each train route is the section where the target stop of the train is set.

[0015] As a preferred technical solution, each of the sections is redefined, and each of the sections includes section information, parking point information, and destination coding information.

[0016] As a preferred technical solution, this method defines two target points for each train when compiling a train operation plan, one is the "stop target point" and the other is the "terminal target point", and establishes and locks the route based on the train's location and the "stop target point".

[0017] As a preferred technical solution, the "stopping target point" determines the terminal of the initial route and controls the train to stop at the target point.

[0018] As a preferred technical solution, the "terminal target point" controls the train to update the next parking target point after the train stops at the "stop target point".

[0019] As a preferred technical solution, this method marks each route, that is, the route set and established for the train can only be used by the current train, and other trains will not be allowed to use it.

[0020] As a preferred technical solution, the method specifically comprises the following steps:

[0021] Step S1, route establishment initialization process;

[0022] Step S2, route establishment and locking process;

[0023] Step S3, unlocking process of the route;

[0024] Step S4, the process of cancelling the route.

[0025] As a preferred technical solution, the specific process of step S2, route establishment and locking process is as follows:

[0026] Step S201, taking the train as the object, setting instructions for a "stop target point" and a "terminal target point" for the train;

[0027] Step S202, the route control system traverses all routes according to the train position and the "stop target point" information, and generates a route establishment instruction for the shortest path;

[0028] Step S203, according to the train destination and the occupancy of the triggering section, the route between the section where the train is located and the section where the "stop target point" is located is requested to be established;

[0029] Step S204, when the route establishment conditions are met, the route is established and locked.

[0030] As an optimal technical solution, the starting point of the route is the section where the train is located, and the end of the route is dynamically adjusted according to the restriction point in front of the route. If a signal in backup mode is configured, the signal on the route will be lit after the route is established.

[0031] As a preferred technical solution, the unlocking process of the route in step S3 is specifically as follows:

[0032] For non-branched routes, the route control system performs dynamic unlocking as the train moves based on the real-time position sent by the train;

[0033] For the switch section, a "switch protection zone" is defined based on information such as the switch core, switch tip, warning mark, and switch direction. The approach to the switch area can only be unlocked after the train moves and clears the protection area.

[0034] As a preferred technical solution, the process of canceling the route in step S4 is specifically as follows:

[0035] The train route is cancelled by canceling the "stop target point" and "terminal stop point" set for the train;

[0036] After the route is cancelled, if the area where the train is located is a switch area, the switch at the train's location and the corresponding protective switch will remain in a locked state.

[0037] According to a second aspect of the present invention, there is provided an electronic device, comprising a memory and a processor, wherein a computer program is stored in the memory, and the method described above is implemented when the processor executes the program.

[0038] According to a third aspect of the present invention, there is provided a computer-readable storage medium having a computer program stored thereon, wherein the program implements the method described above when executed by a processor.

[0039] Compared with the prior art, the present invention has the following advantages:

[0040] 1. The present invention manages the routes by taking trains as objects, and can flexibly control the establishment, locking, unlocking and cancellation of the routes, and is no longer dependent on the arrangement of signal machines, thereby achieving the goal of flexible operation and saving construction investment.

[0041] 2. The present invention can realize turning back at any point on the main line, thereby improving the efficiency of operation organization.

[0042] 3. The present invention does not require a separate lead-out line to be set up in the field section, thus saving construction investment.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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 should fall within the scope of protection of the present invention.

[0050] The present invention provides a route control method for trains. The present invention is implemented by the following technical solutions:

[0051] The route control is not based on the signal, but on the train. However, in order to consider the use in the backup mode, the signal can be configured as needed, but the signal is only used as a backup driving certificate and is not the object of route control.

[0052] First, the line is divided into several axle-counting sections according to its scale. As the smallest unit of the route, each train route can be composed of one section or several sections and can be flexibly configured.

[0053] The starting point of each train route is the section where the train is located, and the end point of each route is the section where the target stop of the train is set.

[0054] The attributes of each section are redefined, and each section needs to include section information, parking point information, destination code information, etc. The parking point information is stored in the vehicle electronic map, and the destination code is stored in the ATS system.

[0055] When compiling a train operation plan, two target points are defined for each train. One is the "stop target point" and the other is the "terminal target point". The route is established and locked according to the train's location and the "stop target point". The "stop target point" determines the terminal of the initial route and controls the train to stop at the target point. The "terminal target point" controls the train to update the next stop target point after stopping at the "stop target point". In special cases, the "stop target point" and the "terminal target point" can be the same point.

[0056] Each route is specially marked, that is, the route set and established for the train can only be used by the current train, and other trains will not be allowed to use it.

[0057] 1. The method of establishing the route is as follows:

[0058] 1) Taking the train as the object, set the instructions of "stop target point" and "terminal target point" for the train.

[0059] 2) The route control system traverses all paths according to the train position and the "stop target point" information, and generates a route establishment instruction for the shortest path.

[0060] 3) According to the train destination and the occupancy of the triggering section, the route between the section where the train is located and the section where the "stop target point" is located is requested to be established.

[0061] 4) After the relevant route establishment conditions are met (such as no hostile routes, correct switch position, etc.), the route is established and locked.

[0062] 5) The beginning of the route is the section where the train is located, and the end of the route is dynamically adjusted according to the restriction point in front of the route.

[0063] 6) If a signal light in backup mode is configured, the signal light on the approach will be lit after the approach is established.

[0064] 2. Method of unlocking the access route:

[0065] 1) For non-branch routes, the route control system dynamically unlocks the route based on the real-time position sent by the train as the train moves. The unlocked section can be used by subsequent train routes.

[0066] 2) For the switch section, a "switch protection zone" is defined based on the switch core, switch tip, warning mark, switch direction and other information. The approach to the switch area can only be unlocked after the train moves and clears the protection area.

[0067] 3. Manual cancellation method of route:

[0068] 1) The train route is cancelled by canceling the "stop target point" and "terminal stop point" set for the train.

[0069] 2) After the route is cancelled, if the area where the train is located is a switch area, the switch at the train's location and the corresponding protective switch will remain in a locked state. Specific embodiments

[0071] The method of the present invention specifically comprises the following steps:

[0072] Step S1, route establishment initialization process;

[0073] Step S2, route establishment and locking process;

[0074] Step S3, unlocking process of the route;

[0075] Step S4, the process of cancelling the route.

[0076] Initialization of route establishment:

[0077] First, the line is divided according to its scale into several axle counting sections, which serve as the smallest unit of the route.

[0078] The attributes of each section are redefined, and each section includes section information, parking point information, destination code information, etc. The parking point information is stored in the vehicle electronic map, and the destination code is stored in the planning control system.

[0079] According to the section where the train is located, the route is established with the train as the object and the target stop point as the destination. In the planning control system, two target points are defined for each train: the stop target point (M1) and the terminal target point (Mn).

[0080] Establishment and locking of routes:

[0081] 1) Set target points for train 1: stop target point M1 and terminal target point Mn. M1 controls the train to stop at the target point, and Mn controls the train to automatically update the next stop target point after stopping at the stop target point M1.

[0082] 2) The route control system traverses all paths based on the position information of train 1 and the "stop target point" information, and generates a route establishment instruction for the shortest path.

[0083] 3) Based on the train destination, a route is requested to be established between the section where Train 1 is located and the section where the "stop target point" is located.

[0084] 4) Check whether the conditions for establishing the route are met, such as hostile routes, side-impact routes, switch positions, etc. If the conditions for establishing the route are met, the route is established and locked. If the conditions are not met, the route cannot be established.

[0085] 5) When there is no other train or route between train 1 and the stopping target point M1, the end position of the route is the section where the target point M1 is located.

[0086] 6) When there are other routes in the same direction between train 1 and target point M1, the target end position of the route is still the section where the stop target point M1 is located, but the actual end position of the route is the rear protection point of the previous sequence car or outside the switch protection area, and the route range can be dynamically extended as the previous sequence car moves until the section where the stop target point M1 is located.

[0087] 7) When there is a turnout between train 1 and target point M1, and there is a train in the turnout area, the end position of the route is outside the turnout protection area or the rear protection point of the train.

[0088] 8) If there is a train 2 between train 1 and the target point M1, but there is no corresponding route for train 2, the end point of the route is the boundary of the axle counting section where train 2 is located.

[0089] 9) If the route includes a turnout, the switch position will be checked to see if it is in the specified position. If not, a turnout operation command will be sent to operate the turnout to the specified position and then lock it.

[0090] 10) If a traffic light is included in the route range, a lighting command will be triggered after the route is established to control the traffic light.

[0091] 11) The direction of the route is determined by the route control system based on the train position and the target point. After the route is locked, the route direction will be sent to the train control system, and the train control system will control the train operation based on the route direction.

[0092] 12) After train 1 reaches the stop target point M1, the next stop target point is automatically updated according to the defined Mn, and the route to the next stop target point is automatically processed according to the next stop target point information.

[0093] Unlocking the route:

[0094] 1) For non-branch routes, the route control system dynamically unlocks the route based on the real-time position sent by the train as the train moves. The unlocked section can be used by subsequent train routes.

[0095] 2) For the switch section, a protection area is defined based on the switch core, switch tip, warning mark, switch direction and other information. After the train moves and clears the protection area, the approach to the switch area is unlocked.

[0096] Cancellation of access:

[0097] 1) The processed route is cancelled by canceling the "stop target point" and "terminal target point" set for the train.

[0098] 2) When the train's terminal destination point Mn is cancelled, the train runs to the next stop destination point M1 and stops. The train's subsequent destination points are no longer updated and the subsequent route cannot be processed.

[0099] 3) When the next target stop point M1 of the train is cancelled, but the terminal target point Mn still exists, the running train will stop with emergency braking, but the route prepared for the train will not be cancelled.

[0100] 4) When the next stop target point M1 and the terminal target point Mn of the train are cancelled at the same time, for a running train, the route is unlocked immediately after the train stops. For a stationary train, the route is unlocked immediately after M1 and Mn are cancelled.

[0101] 5) If the area where the train is located is a switch area, the switch at the train's location and the corresponding protective switch remain in a locked state.

[0102] The following is a detailed description of route establishment, route unlocking, route cancellation, etc. in the above scheme through specific examples:

[0103] The initial conditions are as follows Figure 2 As shown in the figure, the rear axle counting points AC01, AC02, AC03,

[0104] AC04, AC05, AC0n-1, AC0n, respectively correspond to sections TC12, TC23, TC34, TC45 and TCn. TC34 is a turnout section, including turnout P1. Train 1 is located on section TC12. Section TC45 is the stop target point of train 1, marked as M1, and TCn is the terminal target point of train 1, marked as Mn. One approach is set from axle counting point AC01 to AC03, and another approach is set from AC03 to AC05.

[0105] The process of establishing a route, such as Figure 3 As shown:

[0106] Step 1: Train 1 is located in section TC12, and target stop points M1 and Mn are set for train 1.

[0107] Step 2: If Figure 3 As shown in scenario 1, when there are no other trains or routes between sections TC12 and TC45, after the route establishment conditions are met, routes R1 and R2 between sections TC12 and TC45 are established and locked, and the train running direction information is established and sent to the train control system for controlling the train running direction.

[0108] Step 3: If Figure 3 As shown in the middle scene 2, when there is train 2 but no route between sections TC12 and TC45, the target point of the route is still M1. After the route establishment conditions are met, the route from section TC12 to the boundary point AC03 of the section where train 2 is located is established and locked. When train 2 arrives at section TC45 and leaves section TC34, the route terminal of train 1 will be at AC04.

[0109] Step 4: Figure 3 As shown in scene 3, when there is train 2 and the corresponding route between sections TC12 and TC45, after the route establishment conditions are met, routes R1 and R2' from section TC12 to the rear protection point of train 2 are established and locked. As train 2 moves forward, R2' will be dynamically established and locked as the rear protection point of train 2 moves.

[0110] Step 5: Figure 3 As shown in scene 4, when there is train 2 and the corresponding route is located in the switch protection zone between sections TC12 and TC45, after the route establishment conditions are met, the routes R1 and R2' from section TC12 to the boundary of the switch protection zone are established and locked. As train 2 moves forward and clears the switch protection zone, R2' will be dynamically established along with the protection point at the rear of train 2.

[0111] Unlocking process:

[0112] For non-branching routes, the route control system dynamically unlocks R1 based on the real-time position sent by Train 1 as the train moves. The unlocked section can be used by subsequent train routes.

[0113] For the switch section, a "switch protection area" is defined based on the switch core, switch tip, warning mark, switch direction and other information. After train 1 moves and clears the protection area, the approach to the switch area is immediately unlocked.

[0114] The process of route cancellation:

[0115] Cancel the terminal target point Mn of train 1. The train will stop at the stop target point M1. The subsequent target points of the train will no longer be updated and the subsequent route cannot be processed.

[0116] When the target stop point M1 of train 1 is cancelled but the terminal target point Mn still exists, the running train will stop with emergency braking, but the route for the train will not be cancelled.

[0117] After the stop target point M1 and the terminal target point Mn of train 1 are cancelled at the same time, the route is unlocked after the running train stops by emergency braking. For a stationary train, the route is unlocked immediately.
