[0046] The simulation model consists of a train parameter interface, a track information interface, an operating environment simulation, and train operation status calculations. The functions of each component are as follows:

[0047] (1) Train parameter interface: This interface obtains parameters such as the weight, length, maximum acceleration, and maximum speed of the target train to construct the dynamic model of the train.

[0048] (2) Line information interface: This interface mainly obtains information such as the gradient, curvature of curves, location of phase separation zones and length of each block section at various locations on the line, in order to simulate the train operation process.

[0049] (3) Operation environment simulation: This unit mainly constructs the operation environment of the train during operation, including the location of the station, the operation type of the station and the temporary speed limit information of the train section. The temporary speed limit information includes the start and end points of the speed limit, as well as the start and end times of the speed limit.

[0050] (4) Train operation status calculation: This unit mainly constructs a train dynamics model based on the train and line parameter information and operating environment obtained from various interfaces, performs simulation of the train's operation process under the set interference environment, and outputs the train's running time and the delay time caused by the interference event. The specific calculation of the train's running time and delay time is shown in Equation (1) and Equation (2):

[0051] 1) Calculation of running time:

[0052] The running time is calculated using the "distance-step" concept, which involves taking a small distance as the step size and assuming that the net force on the train is constant within this step size. Based on this, the train's acceleration, speed, and travel time are calculated. The total running time of the train is obtained by adding the travel times obtained from multiple step sizes. The specific calculations are shown in formulas (1) to (6). (1)

[0053] In equation (1), and The train is at its position and The acceleration at that point, in m / s² 2 m represents the train's mass in kg; k is the slewing coefficient, indicating the effect of horizontal deviation on acceleration during train operation, with a value ranging from 1.0 to 1.2, used to correct for train acceleration when operating on curves. The maximum permissible acceleration of a train is expressed in m / s². 2 ; The maximum permissible impact rate for the train, expressed in m / s. 3 ; For the train at the previous distance interval The runtime is measured in seconds. For the train in position The net force at a given location, expressed in N, is calculated using the following formula: (2)

[0054] In equation (2), , , , These are the traction force (calculated based on the train traction characteristic curve), braking force (calculated based on braking system parameters), basic resistance, and gradient resistance experienced by the train at position i+1, respectively. and It depends on the operating conditions of the train. , The train is operating under maximum traction conditions; when , The train is under maximum braking conditions. , At that time, the train was in coasting mode; when and Take a certain constant such that At that time, the train was in cruise mode. (3)

[0055] In equation (3), and The train is at its position and The velocity at that location is expressed in m / s. For the train in position The speed limit value at that location, in m / s.

[0057] In equation (4), The train's arrival location At that moment, The train's arrival location The time is expressed in seconds (s). and The train is at its position and The velocity at that location is expressed in m / s. For the train in position The acceleration at that point is expressed in m / s².

[0058] (5)

[0059] In equation (5), It is the total travel time of the train within the current section, that is, the total distance traveled by the train within the current section. The sum of internal running times.

[0060] 2) Calculation of delay time: (6)

[0061] In equation (6), It is the total travel time of the train within the current section, that is, the actual total travel time of the train within the current section. Minimum travel time between train sections The difference, the minimum running time of the train. It was calculated under undisturbed conditions.

[0062] Step S220: Construct a train delay prediction model. Use a neural network model (such as LSTM) to learn the temporal features in historical operation data. Through the structure of input layer, hidden layer (128 nodes), and output layer (linear activation function), train the model with mean squared error as the loss function to fit the relationship between the delay of the target station and historical features. Use the neural network model to learn the feature information related to delay in the historical operation data of trains. Fit the relationship between the delay of the target station and historical operation features through the neural network to predict train delays.

[0063] The main units of the train delay prediction model include a historical operation information interface module, a delay feature processing module, a neural network prediction module, and a delay prediction output module.

At the same time, it receives the delay time information generated under interference events obtained from the train operation simulation model, providing data support for the delay prediction of the target train at the next station.

[0065] (2) Late arrival feature processing module: This module mainly processes the acquired historical information, filters out erroneous information, selects feature information for late arrival prediction, and processes the feature information into the corresponding data structure according to the requirements of neural network input.

It can identify features related to delays in train operation information, capture the temporal relationship in train operation information, and predict the train's delay time at the next station.

[0067] Step S230: Construct a train timetable prediction model. Based on the predicted delay information and train operation constraints, predict the impact of the current train delay on subsequent trains, thereby obtaining the overall train timetable prediction under interference conditions.

[0068] The main units of the real-time train timetable simulation model include the actual planned timetable interface module, the future timetable prediction module, and the train delay status display module.

[0069] (1) Actual planned operation diagram interface module: This module is mainly used to transmit the actual planned operation diagram information of the train, providing a basis for real-time updates of the future train operation diagram based on the train's delay situation.

[0070] (2) Train delay situation information receiving module: This module mainly receives train delay prediction situation information, providing conditions for future timetable prediction and overall analysis.

[0071] (3) Train operation condition judgment module: This module mainly analyzes whether the trains fail to meet the relevant operation conditions due to delays, thereby determining the range of delay propagation. The relevant operation constraints involved are shown in equations (7) to (8).

[0072] 1) Arrival time constraint: (7)

[0073] This constraint ensures that the train's arrival time is no earlier than the sum of the scheduled arrival time and the delay time.

[0074] 2) Departure time constraints: (8)

[0075] This constraint ensures that the train's departure time is no earlier than the scheduled departure time.

[0078] 4) Departure time interval constraint: (10)

[0079] This constraint ensures that the departure time interval between any two trains is not less than the minimum safe interval.

[0080] (4) Future train schedule prediction module: This module mainly combines the actual planned train schedule, train delay information at future stations, and train operation conditions to deduce the overall impact on trains in order to predict future train schedules.

[0083] Step S320: Input the actual historical train operation information and the simulated train operation time under interference conditions into the train delay prediction model to predict the delay time at future stations under train interference scenarios.

[0084] Step S330: Combine the train operation plan and train simulation operation information to deduce the trains affected by the interference event, and based on the predicted delay events obtained from the delay prediction model and the train operation constraints, deduce the current train delay propagation range, obtain the overall train delay situation, and draw the future operation diagram prediction situation.

[0085] Step S400: Perform fusion analysis on the various outputs obtained from the model to obtain comprehensive train delay situation information and display it visually.

[0086] Step S410: Display the progress of train operation information under interference, including the train's simulated operation curve, train operation time, and the delay time caused by the interference.

[0087] Step S420: Combine the future station delay prediction results obtained from the train delay prediction model with the train operation constraints to output the overall affected trains and their respective station operation delay information.

[0088] Step S430: Based on the overall operational delay forecast information, the future train operation map is updated in real time and displayed intuitively.

[0089] Example

[0091] Step S100: Design a comprehensive high-speed rail delay situation information inference system with multi-information collaboration. Data flow is as follows: Figure 2 As shown.

[0092] according to Figure 2 The external data required for the high-speed rail train delay situation visualization software includes the actual operation plan of the CTC system, actual train operation data, track conditions, train parameters, and interference scenario information. The actual operation plan of the CTC system is connected to the delay situation prediction system via a data interface to simulate the propagation of delays between trains, resulting in a projected display of the future timetable. The actual train operation data, after data processing, extracts delay-related input features to input into the delay prediction neural network model. Track conditions, train parameters, and interference scenarios are used to construct a train operation simulation model to obtain information on delays caused by operational interference. The actual delay data and delay information caused by operational interference are fused and input into the high-speed rail delay situation prediction system according to a specified format. The system's built-in delay prediction algorithm predicts train delays and performs timetable analysis based on train operation constraints. The resulting operational situation information, delay prediction results, and future timetable are then visualized and output.

[0093] Step S200: Design a visualization interface for a comprehensive high-speed rail delay situation information simulation system that integrates multiple information collaborations, such as... Figure 3 As shown.

[0094] according to Figure 3 A comprehensive high-speed rail delay situation information simulation system with multi-information collaboration features a visual interface consisting of a train section parameter setting panel, a train speed limit information setting panel, a train timetable information setting panel, a train operation process curve calculation and display panel, and a dynamic train timetable display panel. The main functions of each part are as follows:

[0096] (2) Train speed limit information setting panel, used to set the number of speed limit sections, the start and end points of each speed limit section and the speed limit value.

[0097] (3) Train timetable information setting panel, used to set the date of the train timetable to be retrieved, the time range of the timetable to be displayed, the up and down selection, and the current time;

[0098] (4) Train operation process curve calculation and display panel, used to display the VT diagram, ST diagram and VS diagram of the train operation process, and calculate the initial delay information of each station generated by the slow train under the speed limit.

[0099] (5) The dynamic display panel of the train timetable is used to show the impact of the speed limit conditions set on the overall train operation, including the train numbers that will be affected by the speed limit, the delay information of each station affected by the speed limit, and the predicted train timetable after the impact.

[0100] Step S300: Select the intercity route from Beijing to Tianjin, and use the high-speed rail situation information simulation system to conduct a high-speed rail delay situation simulation analysis. Specific results are as follows: Figure 4 As shown.

[0101] Step S310: Input the starting position, ending position, maximum speed limit, station speed limit, and minimum interval time of the line through the train section parameter setting panel. The starting position is 0, the ending position is 118100m, the initial speed limit is 350km / h, the station speed limit is 80km / h, and the minimum interval time is 3min.

[0102] Step S320: Input and set the information of the speed limit section through the train section parameter setting panel. First, input the number of speed limit sections "1", and click "Confirm". After clicking "Confirm", the system will pop up a corresponding pop-up window based on the number of speed limit sections to further input the speed limit section information. Set the starting position of the speed limit section to 35000m, the ending position to 45000m, and the speed limit value to 120km / h.

[0103] Step S330: Set the date of the train schedule to be retrieved through the train schedule input panel, such as "10-08". Enter the "start time" and "end time" to display the time range of the train schedule. At the same time, select the direction of train operation to be displayed, "up" or "down", and set the current time. The current time is the time when the speed limit is issued. Different times when the speed limit is issued will affect the range of trains affected.

[0104] Step S360: After selecting the different train operation curves to be calculated and plotted, such as "VT," "ST," "VS," "AS," or "AT," click the "Calculate Train Operation Status" button to obtain different train operation curve diagrams. After clicking the "Calculate Train Operation Status" button, a pop-up window will first appear indicating "Save Successful," stating that "Position and running time data have been saved to the file: position_runtime_data_limited.txt." This file records the running time of the trains reaching various positions under the influence of the set speed limit conditions, obtained from simulation calculations. The first column records the specific position in "km," and the second column records the running time corresponding to each position in "s." After clicking the "Confirm" button in the pop-up window, the operation curves will be displayed in the right column of the main interface. Simultaneously, the "Initial Delays Caused by Passing Through Speed ​​Limit Sections" column below will output the initial delay time information caused by the train slowing down upon entering the speed limit section. Specific results are as follows... Figure 4 As shown.

[0105] Step S370: After obtaining the initial delay information of trains affected by the speed-limited section by calculating the train operation status, select the train running direction, and then click the "Display Train Timetable" button to obtain the overall train timetable affected by the speed limit. The specific results are as follows: Figure 5 As shown, the blue section represents the planned train routes, while the red section represents the stations and subsequent routes of trains predicted to be delayed due to speed restrictions, indicating a change in the original plan. The right-hand column displays the train numbers affected by speed restrictions, including trains passing through the speed-restricted section at the current time and trains delayed due to the delay of preceding trains, along with specific predicted delay information for each train at each station.

[0106] In summary, this invention proposes a comprehensive high-speed rail delay situation information simulation system based on multi-information collaboration. This system integrates models such as train operation simulation, delay information prediction, and train timetable simulation. After comprehensive analysis and processing of data from each model, it obtains comprehensive and detailed train delay simulation results and visualizes the overall train delay situation. This comprehensive high-speed rail delay situation information simulation system obtains multiple information, including the simulation of interference events by the comprehensive train operation model, historical train operation data, and train operation constraints, forming a more comprehensive delay analysis result.
