Embodiment 1

[0052] figure 1 It is a schematic diagram of the train dynamic adjustment method under the emergency of Embodiment 1 of the present invention, referring to figure 1 , the method includes:

[0053] S1 records the historical mapping data under all emergencies, collects the data information of trains in the same direction at the same time as the current emergency, determines the operating scene conditions of the trains, and builds a scene library according to the data information and operating scene conditions;

[0054] S2 retrieves the historical mapping data corresponding to the same period and direction under the current emergency, and establishes an environmental model based on the historical data set according to the historical mapping data and the Markov decision process;

[0055] S3 establishes an environment model according to the scene library and the environment model based on the historical data set, and learns the environment model through an agent to obtain a train ...

Embodiment 2

[0137] Image 6 It is a schematic diagram of the train dynamic adjustment system under the emergency of Embodiment 2 of the present invention, referring to Image 6 , the system includes: information collection module, data storage module, scene library building module, model training module and model output module;

[0138] The information collection module is used to collect the data information of the train in the same direction at the same time period as the current emergency;

[0139] The data storage module is used to store the data information collected by the information collection module and store the historical mapping data under all emergencies, as well as the operating scene conditions of the train;

[0140] The scene library building module is used to call the information in the data storage module to build the scene library;

[0141] The model training module is used to call the historical map data in the data storage module and the scene library built by the sce...

Embodiment 3

[0154] Figure 7 It is a schematic diagram of the simulation interface of the train dynamic adjustment system under the emergency of Embodiment 3 of the present invention, referring to Figure 7 , the system includes 5 parts: information collection module, data storage module, scene library building module, model training module and model output module.

[0155] Wherein, the content in the information collection module includes train number, train status, train running direction, emergency type and train schedule information. This module can collect the information of any train in the basic plan operation diagram of the train. Taking the train G17 of a certain train on the Beijing-Shanghai High-speed Line as an example, the train status is set to be in operation, and the train running direction is automatically set to down according to the train number. , the emergency type is set to natural factors: strong wind (level 8), and the train timetable information automatically sho...

Abstract

The present invention provides a method and system for dynamic adjustment of trains under emergencies, including: recording historical map adjustment data under all emergencies, collecting data information of trains in the same direction at the same time as the current emergency, and determining the train's Operating scenario conditions, build a scenario library based on data information and operating scenario conditions; establish an environmental model based on historical data sets based on historical map data and Markov decision-making processes; Carry out in-depth reinforcement learning to obtain the train dynamic adjustment model; through the train dynamic adjustment model, online dynamic adjustment is made to the actual performance operation diagram of the trains in the same direction at the same time period during the current emergency. This method improves the speed and quality of dynamically adjusting the approximate optimal feasible solution, and solves the problem of dynamic adjustment of the actual train operation diagram under emergencies.

Description

technical field [0001] The invention relates to the field of railway operation dispatching, in particular to a method and system for dynamically adjusting trains under emergencies. Background technique [0002] With the proposal of the strategy of "transportation power, railway first" and the construction of a huge operating mileage, the modern high-speed railway network of "eight horizontal and eight vertical" will realize interconnection in 2035. The running state of trains under networked operating conditions has the characteristics of nonlinearity, rapid evolution, and instability. If a fault occurs on the line is not handled properly, the delay of a train on the line will quickly spread to other trains on the line and to other trains on the line. Cross-line trains adjacent to the line will directly affect the operating capacity of the railway line and the operating efficiency of the train. At present, the emergency response to railway emergencies is still mainly handle...
