[0049] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.
[0050] With the continuous development of the train field, in order to ensure the reliability of each train management, a virtual coupling (Virtual Coupling / Platooning) technology appears, which allows two or more physically separated trains to run closely in logic through wireless communication and advanced control algorithm, like a coupled train. In addition, train departure is also a key link of train operation control, and accurate departure time is crucial for driver operation, station scheduling and timetable execution.
[0051] However, the prior art generally determines the train departure time of the train based on a static timetable only, ignoring the influence of other train running states and other factors on train departure, which reduces the reliability of train departure time and thus reduces the reliability of train operation.
[0052] Based on this, in an exemplary embodiment, a departure time determination method is provided, which is applied to a computer device for example. The computer device can be a server or a terminal with powerful computing function. As shown in the figure, it specifically includes the following steps: Figure 1
[0053] S101, in response to a request for determining the departure time of a target train, obtaining the ground signal state associated with the target train and the running plan information of the target virtual coupling train team where the target train is located.
[0054] Wherein, the so-called target train is any train that has a running plan and is waiting for departure; the so-called request for determining the departure time is a request for determining the departure time of the target train; the so-called ground signal state is the state of the ground signal at the current time; the so-called target virtual coupling train team is the virtual coupling train team where the target train is located.
[0055] The so-called running plan information is the running plan of each train in the target virtual coupling train team. It is worth noting that in order to ensure the flexibility of the plan, the train stop time, communication establishment timeout threshold, signal prediction model parameters and other parameters in the running plan information can be manually configured.
[0056] Optionally, after detecting the departure time determination request for the target train, the ground signal state of the ground signal in front of the target train on the running track of the target train can be acquired according to the running track of the target train; and the running plan information of the target virtual marshalling train can be acquired by querying the train identification of the target train in the running plan information of each train team. In order to ensure the reliability of information acquisition, the computer device needs to establish a reliable data interface with the train management system (TMS), the interlocking system, the wireless communication system, the dispatching system, etc.
[0057] It is worth noting that in the case of missing information, the missing information can be filled with preset default values or historical values. After determining the train departure time, the train departure time is marked as “to be determined”, and an information missing prompt is given.
[0058] S102, determining the train team formation opportunity of the target virtual marshalling train according to the running plan information.
[0059] The so-called train team formation opportunity is the opportunity of train team formation, which can include pre-departure formation and post-departure formation; further, the pre-departure formation is the whole departure, and the post-departure formation is the independent departure or small marshalling departure.
[0060] Optionally, the train team formation opportunity of the target virtual marshalling train can be determined based on the departure time of each train in the running plan information.
[0061] S103, determining the train departure time of the target train according to the train team formation opportunity, the running plan information and the ground signal state.
[0062] The so-called train departure time is the departure time of the target train.
[0063] Optionally, the departure time determination logic corresponding to the train team formation opportunity can be selected based on the train team formation opportunity, and then the running plan information and the ground signal state are processed based on the selected departure time determination logic, so as to obtain the train departure time of the target train.
[0064] For example, a departure time determination model for two different formation modes can be trained in advance, and then the running plan information and the ground signal state are input into the corresponding departure time determination model, and the departure time determination model outputs the train departure time according to the running plan information and the ground signal state.
[0065] It is worth noting that in order to ensure the reliability of the train departure time, the above-mentioned calculation logic of the train departure time needs to be repeatedly executed at a high frequency (for example, every second or triggered according to state change events), so as to realize the real-time dynamic update of the train departure time.
[0066] In the train departure time determination method, in response to a train departure time determination request for a target train, ground signal state associated with the target train and operation plan information of a target virtual marshalling train team in which the target train is located are acquired, and a train team formation opportunity of the target virtual marshalling train team is determined according to the operation plan information. Then, the train departure time of the target train is determined according to the train team formation opportunity, the operation plan information and the ground signal state. Compared with the related art in which the train departure time of the train is determined based on a static timetable, the train departure time of the target train is determined according to the train team formation opportunity, the operation plan information and the ground signal state in the method, so that the comprehensiveness and accuracy of the determination of the train departure time are ensured, and the reliability of train operation is improved.
[0067] On the basis of the above-mentioned embodiments, in the embodiments of the present application, an optional method for determining the train departure time is provided, as shown in the following Figure 2 The method comprises the following steps:
[0068] S201, determining a departure reference time and a preparation completion time of the target train according to the train team formation opportunity and the operation plan information.
[0069] The departure reference time is a basic train departure time. The preparation completion time is a preparation time required for train departure.
[0070] Optionally, the train team formation opportunity and the operation plan information can be input into a trained reference time calculation model at the same time, and the reference time calculation model outputs the departure reference time of the target train according to the train team formation opportunity and the operation plan information.
[0071] Alternatively, different reference time calculation logics can be selected based on the train team formation opportunity, and then the operation plan information is processed based on the selected reference time calculation logic to obtain the departure reference time of the target train.
[0072] Optionally, the preparation completion time of the target virtual marshalling train team can be determined according to the train departure preparation time of each train in the operation plan information. The train departure preparation time of each train can include, but is not limited to, technical preparation completion time and work preparation completion time.
[0073] For example, the maximum time of the technical preparation completion time and the work preparation completion time of each train can be directly taken as the preparation completion time of the target virtual marshalling train team.
[0074] S202, determining a signal opening time of the ground signal according to the ground signal state and the operation plan information.
[0075] The ground signal is a fixed signal device installed beside the railway track (on the ground) and used to transmit key information such as driving commands, line states, and allowable operation conditions to the train driver. The opening refers to the fact that the train can pass the ground signal. Further, the signal opening time refers to the time at which the ground signal indicates opening.
[0076] Optionally, the signal opening time of the ground signal in front of the target train can be predicted based on the ground signal state of the ground signal in front of the target train and the track operation information in the operation plan information. For example, the ground signal state and the operation plan information can be simultaneously input into a trained signal prediction model, and the signal prediction model can predict the signal opening time of the ground signal based on the ground signal state and the operation plan information.
[0077] S203, determining the train departure time of the target train according to the departure reference time, the preparation completion time, and the signal opening time.
[0078] Optionally, after the departure reference time, the preparation completion time, and the signal opening time are calculated, the train departure time of the target train can be selected from the departure reference time, the preparation completion time, and the signal opening time. For example, the maximum time among the departure reference time T, the preparation completion time T ready , and the signal opening time T signal_est may be selected as the train departure time T dep of the target train.
[0079] In the embodiments of the present application, by determining the departure reference time, the preparation completion time, and the signal opening time, and determining the train departure time of the target train according to the departure reference time, the preparation completion time, and the signal opening time, the reliability of the train departure time determination can be ensured.
[0080] On the basis of the above-mentioned embodiments, in the embodiments of the present application, an optional way of determining the departure reference time is provided. Specifically, when the train formation time is before the train departure, the train departure time of the target virtual formation train in the operation plan information is used to determine the departure reference time of the target train. When the train formation time is after the train departure, the preset departure time, the preset arrival time, and the minimum stop time of each train in the target virtual formation train in the operation plan information are used to determine the departure reference time of the target train.
[0081] The train departure time of the target virtual formation train refers to the overall departure time of the target virtual formation train. The preset departure time refers to the departure time of each train in the plan. The preset arrival time refers to the arrival time of each train in the plan. The minimum stop time refers to the stop time of each train at the arrival station.
[0082] Optionally, in the case that the train formation timing is formed before the train departure, the preset train formation time can be stored in the operation plan information, and the train formation time can be obtained as the departure reference time of the target train.
[0083] In the case that the train formation timing is formed after the train departure, the first time of the target train after stopping and departing can be calculated according to the preset arrival time and the minimum stopping time of the target train. Then, the larger time between the preset departure time and the first time of the target train after stopping and departing is selected as the departure reference time of the target train.
[0084] For example, for the train i in the target virtual formation train, the calculation formula T i '=max(T i , T arrival,i +Δt min_dwell ) can be used to determine the departure reference time T arrival,i ' of the target train according to the preset departure time, the preset arrival time T min_dwell and the minimum stopping time Δt i .
[0085] It is worth noting that in the case that the train formation timing is formed before the train departure, and the train formation time does not exist in the operation plan information, the minimum preset departure time can be selected as the candidate departure time from the preset departure time of each train in the target virtual formation train. Then, for each train in the target virtual formation train, the candidate departure time of the train after stopping and departing can be determined according to the preset arrival time and the minimum stopping time of the train. Finally, the train formation time of the target virtual formation train can be determined according to the candidate departure time of each train and the candidate departure time, and the train formation time can be used as the departure reference time of the target train.
[0086] For example, the calculation formula T U ''=max(T U ', max(T arrival,i +Δt min_dwell )) can be used to determine the train formation time T U '' of the target virtual formation train U according to the candidate departure time T U ' (wherein T i '=min(T arrival,i )), the candidate departure time T min_dwell +Δt U of each train after stopping and departing.
[0087] In the embodiment of the present application, the reliability of the departure reference time is ensured by selecting the corresponding calculation logic according to the train formation opportunity, and then determining the departure reference time of the target train by using the corresponding calculation logic.
[0088] On the basis of the above-mentioned embodiment, in the embodiment of the present application, an optional manner for determining the preparation completion time is provided, specifically, in the case that the train formation opportunity is the formation before the train departure, the train preparation time of each train in the target virtual grouping train is determined according to the train preparation time of each train in the target virtual grouping train in the operation plan information, and the preparation completion time of the target train is determined according to the train preparation time of the target virtual grouping train and the communication link establishment time between each train in the target virtual grouping train; in the case that the train formation opportunity is the formation after the train departure, the preparation completion time of the target train is determined according to the train preparation time of the target train in the operation plan information.
[0089] The so-called train preparation time is the preparation time required before the train departure; further, the train preparation time includes the technical preparation time and the operation preparation time. The so-called technical preparation time is the preparation time required before the train departure in the technical dimension; the so-called operation preparation time is the preparation time required before the train departure in the operation dimension.
[0090] The so-called train preparation time of the target virtual grouping train is the departure preparation time of the target virtual grouping train. The so-called communication link establishment time is the time required for establishing the communication link.
[0091] In an optional implementation manner, in the case that the train formation opportunity is the formation before the train departure, the technical preparation time and the operation preparation time of each train in the target virtual grouping train can be obtained from the operation plan information; and for each train, the train preparation time of the train is determined according to the technical preparation time and the operation preparation time of the train. Exemplarily, the larger one of the technical preparation time and the operation preparation time can be taken as the preparation completion time of the train.
[0092] Then, the train preparation times are sorted in descending order, and the train preparation time in the front of the sorting is taken as the train preparation time of the target virtual grouping train. Further, the larger one of the train preparation time of the target virtual grouping train and the communication link establishment time between each train in the target virtual grouping train can be taken as the preparation completion time of the target virtual grouping train, and the preparation completion time of the target virtual grouping train is directly taken as the preparation completion time of the target train.
[0093] Exemplarily, the calculation formula T platoon_ready,U =max(T unit_ready , T comm_ready ) can be referred to, the maximum train preparation time T unit_readyThe communication link establishment time T between the target virtual marshalling train and each train in the target virtual marshalling train comm_ready In the embodiment, the preparation completion time T of the target virtual marshalling train is selected platoon_ready,U .
[0094] In another optional embodiment, in the case of train formation timing after the train departure, only the technical preparation time and the operation preparation time of the target train are obtained, and the greater one of the technical preparation time and the operation preparation time is taken as the preparation completion time of the target train.
[0095] For example, the calculation formula T ready,i =max(T tech_ready,i , T ops_ready,i ) is used to select the greater one of the technical preparation time T tech_ready,i and the operation preparation time T ops_ready,i of the target train i as the preparation completion time T ready,i of the target train.
[0096] In the embodiment, the calculation logic of the corresponding preparation completion time is selected according to the train formation timing, and then the corresponding calculation logic is used to determine the preparation completion time of the target train, so that the reliability of the determination of the preparation completion time is ensured.
[0097] On the basis of the above-mentioned embodiment, in the embodiment, an optional way of determining the signal opening time is provided, specifically, in the case of the ground signal state representing non-opening, the signal opening time of the ground signal is predicted according to the line occupation of the train line where the target train is located, the turnout conversion information in the operation plan information, the train operation information of the target train, and the distance information between the target train and the front vehicle; in the case of the ground signal state representing opening, the current time is determined as the signal opening time of the ground signal.
[0098] The line occupation is the occupation time of the train line where the target train is located by other trains; the turnout conversion information is the turnout conversion between each track line; the train operation information is the operation information of the target train, which can include but is not limited to the operation speed of the train; and the distance information is the distance between the target train and the front vehicle.
[0099] Optionally, in the case that the ground signal state representation is not open, the line occupation on the train line where the target train is located, the turnout conversion information in the running plan information, the train running information of the target train, and the distance information between the target train and the front vehicle can be input into the trained time prediction model at the same time, and the time prediction model outputs the signal opening time of the ground signal according to the line occupation, the turnout conversion information, the train running information, and the distance information. The time prediction model is a machine learning model (such as a regression model or a time series prediction) trained based on historical data and real-time road conditions.
[0100] In the case that the ground signal state representation is open, the current time can be directly taken as the signal opening time of the ground signal.
[0101] It is worth noting that, in order to ensure the rationality of the signal opening time determination, in the case that the ground signal state representation is not open, the signal opening time of the target train needs to be determined in combination with the signal opening time corresponding to each train in the target virtual marshalling train for the train formation before the train departs.
[0102] In the embodiments of the present application, the signal opening time of the ground signal is predicted according to the line occupation on the train line where the target train is located, the turnout conversion information in the running plan information, the train running information of the target train, and the distance information between the target train and the front vehicle, which can ensure the reliability of the signal opening time prediction.
[0103] On the basis of the above-mentioned embodiments, in the embodiments of the present application, an optional information display method is provided, as shown in Figure 3 The method specifically includes the following steps:
[0104] S301, in the case that the train departure time is later than the current time, the departure countdown information of the target train is determined according to the train departure time and the current time.
[0105] The so-called departure countdown information is the countdown of the departure of the target train.
[0106] Optionally, in the case that the train departure time is later than the current time, the difference between the train departure time and the current time can be taken as the departure countdown information of the target train. For example, the formula T Countdown,i =max(T dep -T current , 0) can be referred to, in which the larger value between 0 or the difference between the train departure time T dep and the current time T current is selected as the departure countdown T Countdown,i of the target train.
[0107] S302, display the departure countdown information through the countdown display page associated with the target train.
[0108] The countdown display page is a display page for displaying the departure countdown of a train.
[0109] Optionally, the departure countdown information can be displayed in the countdown display page in combination with a graphical progress bar, sound prompts, and the like.
[0110] In the embodiments of the present application, the departure countdown information is displayed through the countdown display page associated with the target train, which can ensure the reliability of information display.
[0111] Figure 4 For another flowchart of the departure time determination method in the embodiments, on the basis of the above embodiments, the present embodiment provides an optional example of a departure time determination method. In combination with Figure 4 , the implementation process is as follows:
