Description

Technical Field

[0001] The present invention belongs to the field of railway control technology, and in particular relates to a method, system, device and medium for controlling turnouts of a virtual marshaling train. Background Art

[0002] Compared with the existing CTCS train control system or CBTC train operation control system, the train operation control system based on virtual marshaling has become the current research hotspot and future development direction because of its flexible transportation organization and high operation efficiency.

[0003] Turnout control is an important function of the signal system. After the turnout is locked, it cannot be rotated arbitrarily. It can only be operated after the requisitioned train clears the switch area, so as to ensure the safety of the train passing through the switch area. The virtual marshaling train consists of multiple train units and can be regarded as a train during operation. In order to ensure that the train formation can pass through the turnout smoothly, the current method is to apply for exclusive locks, shared locks, etc. for the turnout to manage the turnout resources and ensure that the turnout will not be requisitioned by other trains when the virtual marshaling train formation passes through the turnout. However, under this method, the virtual marshaling train formation always remains as a whole, and the formation of the train formation does not change. It is also a feasible way to disassemble and re-form the virtual formation, but this method is less efficient.

[0004] Virtual train transportation is organized in a flexible way. Using turnouts to change the formation of virtual trains is a common method. Therefore, how to efficiently control and manage turnouts to adapt to changes in virtual train formations is a problem. 1. It cannot meet the needs of changing the formation of virtual marshaling trains in the switch area; 2. It cannot meet the efficiency requirements of changing the formation of virtual train formations in the switch area.

[0005] Therefore, it is necessary to provide a new virtual marshaling train turnout control method, system, equipment and medium to solve the above technical problems. Summary of the invention

[0006] The purpose of the present disclosure is to provide a virtual train turnout control method, system, device and medium in order to solve the above problems.

[0007] The present invention achieves the above-mentioned purpose through the following technical solutions: A virtual marshaling train turnout control method comprises the following steps: Determine a virtual marshaling train head car from among multiple train formation head cars, and prioritize the trains in the current train formation; Issue the driving plan to the head car of each train formation; Plan the driving path for each train formation, predict the time for each train to pass each switch, and send path information to the head car of each train formation; Apply for primary locking and accompanying time to the switch, and send the information of trains to be passed and the priority information of each train to the switch; Control the leading car of each train formation to apply for secondary locking of the switch. After the secondary locking is successful, the train passes within the specified time; Calculate the time it takes for a train formation to pass through the turnout, and complete the secondary locking of each train according to the train priority; Make the virtual train pass through the turnout.

[0008] As a further optimization scheme of the present invention, trains with the same departure time can be formed into a virtual train to be formed into a formation, and the train priorities include highest priority, high priority, second priority and low priority; the lead car has the highest priority; the train whose destinations of the next two stations are the same as the lead car has a high priority; the train whose destination of the next station is the same as the lead car and whose destination of the second station is different from that of the lead car has a second priority; the train whose destination of the next station is different from that of the lead car has a low priority.

[0009] As a further optimization solution of the present disclosure, the driving plan includes departure time, destination and train information in the train formation.

[0010] As a further optimization scheme of the present disclosure, the additional time is based on the train departure time, taking into account the time for the train to run to the switch, the turnout rotation and locking, the train passing, until it completely leaves the switch area or station.

[0011] As a further optimization scheme of the present disclosure, the first-level locking is that the determined virtual marshaling train head car locks the original head car of each train formation in the virtual marshaling train. After the first-level locking, only the virtual marshaling train head car in the white list can apply for locking to the switch within the attached time.

[0012] As a further optimization scheme of the present invention, the secondary locking is that the head car of each train formation applies for locking to the switch, and the locking method is the locking of the head car of the train formation, including train formation locking and single car locking. Once locked, the train can only be locked by other trains after the locking object passes.

[0013] As a further optimization scheme of the present disclosure, the locking order determination of turnouts for trains with the same priority level includes: If the trains have the same priority, the locking order is determined by calculating the minimum total time T of the trains waiting to pass the turnout. The formula is as follows: Ti=∑(t 1i +t 2i +t 3i ); ; Among them, t 1i The time it takes for the train to reach the turnout; t 2i is the turnout rotation locking time; t 3i It is the time when the train passes through the switch area.

The secondary locking means that the train passes within the specified time after the train is successfully locked; The time calculation module is used to calculate the time it takes for a train formation to pass through a turnout and complete the secondary locking of each train according to the train priority; The turnout passage module is used to enable the virtual marshaling train to pass through the turnout.

[0019] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figure 1 As shown, a virtual marshaling train turnout control method comprises the following steps: Determine the leading train of a virtual train formation among the leading trains of multiple train formations, and prioritize the trains in the current train formation (adjacent trains in the same running direction are automatically grouped into one formation); Issue the driving plan to the head car of each train formation (the plan includes which cars form a formation, departure time and destination); Plan the driving path for each train formation, predict the time for each train to pass each switch, and send path information to the head car of each train formation; Apply for the first-level lock and the accompanying time to the switch, and send the train information to be passed and the priority information of each train to the switch (which train formations can pass, and the train priority whitelist lock); Control the leading car of each train formation to apply for secondary locking of the switch. After the secondary locking is successful, the train passes within the specified time; Calculate the time it takes for a train formation to pass through the turnout, and complete the secondary locking of each train according to the train priority; Make the virtual train pass through the switch.

[0021] Trains with the same departure time can be formed into a virtual marshaling train to be marshaled. The train priority determination method includes: Highest priority: lead vehicle; High priority: The destinations of the next two stops are the same as those of the lead vehicle; Second priority: the destination of the next stop is the same as the lead vehicle, but the destination of the second stop is different from the lead vehicle; Low priority: The next stop destination is different from the lead vehicle.

[0022] Incidental time calculation methods include: The time period from the departure time of the train to the turnout, the turnout rotation and locking, the train passing, etc. is taken as the benchmark, and the time period from the train running to the turnout (or station) is taken as the benchmark. For example, the additional time can be calculated based on the departure time of the last train to the exit station, while considering a certain margin.

[0023] Turnout locking methods include: Turnout locking is divided into primary locking and secondary locking.

[0024] The first-level locking is to lock the original leading cars in the virtual train for the determined leading car of the virtual train. After the first-level locking, only the leading car of the virtual train in the white list can apply for locking to the switch within the attached time.

[0025] Secondary locking is when each leading car applies to the switch for locking. The locking method is the locking of the leading car in the train formation, which can include train formation locking and single car locking. Once locked, the train can only be locked by other trains after the locked object passes. The granularity of secondary locking can be down to a single train. It is not that the entire train formation can be locked by other trains after it passes, but that the switch can be locked by other trains after the locked object, such as a single car or multiple cars, passes.

[0026] The method for determining the locking order of turnouts for trains with the same priority level includes: The one with higher priority will pass first. If the priorities are the same, the locking order is determined by calculating the minimum total time T of the turnout trains to be passed. This method can be applied locally or globally. The formula is as follows: Ti=∑(t 1i +t 2i +t 3i ); ; Among them, t 1i The time it takes for the train to reach the turnout; t 2i is the turnout rotation locking time (0 if the direction is the same as the train running direction; a fixed value if the direction is different from the train running direction); t 3i It is the time when the train passes through the switch area.

[0027] like Figure 2 As shown, an embodiment of the present disclosure provides a virtual marshaling train turnout control system, comprising: A priority sorting module is used to determine the leading car of a virtual train formation among the leading cars of multiple train formations and to prioritize the trains in the current train formation; The plan issuing module is used to issue the driving plan to the head car of each train formation; The path planning module is used to plan the driving path for each train formation, predict the time when each train passes each switch, and send path information to the head car of each train formation; The primary locking module is used to apply for primary locking and the accompanying time to the switch, and send the information of the trains to be passed and the priority information of each train to the switch; The secondary locking module is used to control the head car of each train formation to apply for secondary locking to the turnout. The secondary locking means that the train passes within the specified time after the train is successfully locked; The time calculation module is used to calculate the time it takes for a train formation to pass through a turnout and complete the secondary locking of each train according to the train priority; The turnout passage module is used to enable the virtual marshaling train to pass through the turnout.
