Problems solved by technology

[0009] The disadvantages of existing methods are low efficiency, cumbersome process, and limited scope of application; on the one hand, approach conflicts are avoided by simple space isolation, and there is a lot of room for improvement in efficiency
On the other hand, the existing methods do not consider the method of conflict prediction and isolation from both time and space, and cannot realize the early release of turnout resources

Embodiment 1

[0064] Such as figure 1 As shown, a simulation method based on the prediction of space-time orbital conflict in the throat area includes the following steps:

[0065] a. Establish a station track network model;

[0066] b. Collect the track information, turnout information and occupation time information of each track that the train needs to pass through when using each route in the conflict-free state, and formulate the route information table;

[0067] c. Formulate train timetables based on train number, direction of arrival, direction of departure, time of arrival and time of departure;

[0068] d. According to the train's entry time, entry direction and exit direction in the train timetable, record all the entry routes and the arrival and departure lines where each entry route stops;

[0069] e. According to the prediction calculation, traverse all the routes to judge whether there is a feasible approach to the station, if yes, select one of them as the approach of the t...

Embodiment 2

[0097] In this embodiment, on the basis of Embodiment 1, the step a specifically includes the following steps:

[0098] Collect the track, arrival and departure lines and turnouts in the throat area, and establish a station track network model according to the connection relationship between the track and turnouts in the throat area.

[0099] After modeling, the track is composed of several straight lines and arcs, and the switch connects three tracks;

[0100] The accurate station track network model has a distance accuracy of millimeter level, which reduces the possibility of errors and ensures the accuracy, safety and stability of the simulation process.

Embodiment 3

[0102] In this embodiment, on the basis of Embodiment 1, the following steps are also included between the step c and the step d:

[0103] Import the station track network model, train timetable and route information table for simulation operation.

[0104] By importing the station track network model, train timetable and route information table, the simulation operation of track space-time conflict prediction in the throat area is realized.
