All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow diagram of a rail transit operation simulation system provided in the present invention, and as shown in fig. 1, the system includes:
a scene unit 10, configured to determine a target decision instruction according to a received target operation simulation request;
the model unit 11 is connected with the scene unit 10 and used for determining a target operation simulation model adopted by the rail transit vehicle according to the target decision instruction and performing train operation simulation on the rail transit vehicle according to the target operation data;
and the data unit 12 is connected with the model unit 11 and is used for storing target operation data required by the model unit 11 for train operation simulation.
Optionally, the rail transit operation simulation system provided by the present invention includes a scene unit 10, a model unit 11, and a data unit 12, where the scene unit 10 is configured to analyze a received target operation simulation request to determine a target decision instruction, where the target operation simulation request may be a front-end web page and various external systems that are externally connected to receive various operation simulation requests sent by the front-end web page, such as operation diagram verification requests, passenger flow deduction requests, train operation process analysis requests, and other operation simulation requests. Then, the scene unit 10 determines a target decision instruction according to the received target operation simulation request, and sends the target decision instruction to the model unit 11.
It should be noted that the target decision instruction changes according to a change of the received target operation simulation request, specifically, for example, when the target operation simulation request is an operation diagram verification request, the target decision instruction instructs to select a target operation simulation model for performing operation diagram calculation, and when the target operation simulation model is a passenger flow deduction request, the target decision instruction instructs to select a target operation simulation model for performing passenger flow deduction calculation.
The model unit 11 and the scene unit 10 may be connected by a communication connection method, and receive a target decision instruction sent by the scene unit 10, and then the model unit 11 determines a target operation simulation model adopted by the rail transit vehicle according to the received target decision instruction, and performs train operation simulation and evaluation operation on the rail transit vehicle according to target operation data. Wherein the target operational data is stored in the data unit 12.

The target operation data may be specifically train route data, VOBC data of the vehicle controller, and the like generated during the operation of the train, and different types of data are stored in different universal templates of the data unit 12.

According to the rail transit operation simulation system provided by the invention, through the mutual cooperation of the scene unit, the model unit and the data unit, efficient and accurate simulation and evaluation operation on rail transit vehicles in different scenes can be realized, and operators are assisted to make quick operation decisions.
Further, in an embodiment, as shown in fig. 2, the scene unit 10 may specifically include:
the scene analyzer 101 is configured to determine a target scene and a target scene performance requirement according to the received target operation simulation request, and determine a target decision instruction according to the target scene and the target scene performance requirement;
and the scene library 102 is connected with the scene analyzer 101 and is used for storing the target scene and the target scene performance requirement.
Optionally, the scene unit 10 mainly includes a scene analyzer 101 and a scene library 102, where the scene analyzer 101 is configured to determine a target scene and a target scene performance requirement corresponding to the target scene according to a received target operation simulation request, and determine a target decision instruction according to the target scene and the target scene performance requirement.
The target scenes and the target scene performance requirements corresponding to the target scenes are stored in the scene library 102 in advance, all related scene information is stored in the scene library 102, and each scene information comprises scene input, scene output and scene performance requirements. The scene analyzer 101 extracts relevant information from the scene library 102 according to the input target operation simulation request, and outputs a target decision instruction for the model unit 11 to determine an adopted target operation simulation model according to the target decision instruction.
For example, the following target scenarios and their corresponding target scenario performance requirements are stored in the scenario library 102:
scene 1: when a certain train on the X line breaks down, the state of the whole train changes when the train is guided to be off line under the condition of needing to simulate the X line; because the failure of the train may cause other trains to degrade or stop within the interval, careful simulation of the train operation is required.
Scene 2 is: when an X-line drawing person needs to verify the operation diagram, various operation indexes of the operation diagram need to be obtained. At the moment, the whole train is in a normal state, and at the moment, the operation index of the operation diagram and the line conflict prompt need to be rapidly acquired.
It should be noted that the scenario library 102 may be created by an expert through statistics of different operation scenarios and corresponding performance requirements thereof according to experience.
According to the rail transit operation simulation system provided by the invention, the scene analyzer is utilized to analyze the input simulation request to obtain the target scene and the corresponding performance requirement, and then the target decision instruction is determined according to the target scene and the corresponding performance requirement, so that the model unit can select a proper target operation simulation model according to the target decision instruction to meet diversified simulation operation requirements.
Further, in an embodiment, as shown in fig. 1, the model unit 11 may specifically include:
the target operation simulation accurate model 111 is connected with the scene unit 10 and used for simulating the rail transit vehicle according to the first target operation data;

And the target operation simulation rough model 112 is connected with the scene unit and is used for roughly simulating the rail transit vehicle according to the second target operation data stored in the data unit 12.

The travel direction and the accumulated travel distance may each be divided into first target operational data and second target operational data, wherein the first target operational data is a more detailed explanation of the second target operational data. And after the target operation simulation accurate model 111 acquires the operation direction and the accumulated operation distance data, performing deep analysis, and performing thorough analysis on the rail transit vehicle by using the first target operation data. After the target operation simulation rough model 112 obtains the operation direction and the accumulated operation distance, rough simulation is performed on the rail transit vehicle by analyzing the second target operation data.

The turnout data and the signal machine data are divided into turnout 1-level data and turnout 2-level data according to the data per se detail degree, the signal machine data are divided into signal machine 1-level data and signal machine 2-level data, and the 2-level data is a more detailed explanation of the 1-level data. The method comprises the steps of deeply analyzing train line data of a first preset level, such as turnout 2 level data, and carrying out careful simulation on the train running process.

Optionally, in order to adapt to different scenarios, the target run simulation coarse model 112 in the model unit 11 includes a plurality of coarse submodels supporting different scenarios. For example, a train control operation process rough sub-model for train control operation process simulation, and a passenger flow deduction rough sub-model for train passenger flow volume distribution.
The train control operation process rough sub-model roughly simulates the train operation process according to the train operation diagram data of the second preset level when the second target operation data is the train operation diagram data of the second preset level, such as various operation indexes of the train operation diagram,
for example: in scenario 2 above: when an X-line chart editor needs to verify the operation chart and needs to acquire various operation indexes of the operation chart, and at the moment, the whole train is in a normal state, the train control operation process rough sub-model can be used for analyzing various acquired operation index data of the second preset level operation chart, such as operation index 1 level data, so that the operation indexes of the operation chart and the line conflict prompt are quickly acquired.
