Problems solved by technology

The train coordination control scheme under the complex road network operating conditions needs to calculate and optimize the operating status of a single train on the regional traffic network at the strategic level, and implement collaborative planning for the traffic flow composed of multiple trains; at the pre-tactical level At present, the problem of congestion is solved by adjusting the key operating parameters of some areas on the transportation network through an effective monitoring mechanism. However, there is currently no more accurate solution for the prediction of subway train trajectories and the early warning of train conflicts.

Embodiment 1

[0048] A subway traffic flow optimization control system includes a line topology generation module, a data transmission module, a vehicle terminal module, a control terminal module, and a trajectory monitoring module. The trajectory monitoring module collects train status information and provides it to the control terminal module.

[0049] The control terminal module includes the following submodules:

[0050] Conflict-free trajectory generation module before train operation: According to the planned operation timetable of the train, the train dynamics model is established first, and then the train operation conflict pre-allocation model is established according to the train operation conflict coupling point, and finally the conflict-free train operation trajectory is generated.

[0051] Short-term trajectory generation module for train operation: According to the real-time status information of the train provided by the trajectory monitoring module, use the data mining model ...

Abstract

The invention relates to a metro conflict early warning method. The metro conflict early warning method comprises the following steps that a topological structure chart of a track traffic network is generated according to planned operation parameters of trains; then, based on the topological structure chart, the controllability and sensibility of train flows are analyzed; according to the planned operation parameters of the trains, conflict-free operating trajectories of multiple trains are generated; at each sampling moment, advancing positions of the trains at a certain moment are predicted based on current operating states and historical position observing sequences of the trains, then an observer used from continuous dynamic states of the trains to disperse conflict logics is established, and the continuous dynamic states are mapped into conflict states expressed by disperse observation values; when a system possibly violates a traffic control rule, hybrid dynamic behaviors of the metro traffic hybrid system are monitored, and warning information is provided for a control center. The metro conflict early warning method predicts metro train trajectories in real time in a rolling mode, effectively early warns train conflict and improves the safety of metro traffic.

Description

[0001] The application number of this application is: 201510150113.4, and the name of the invention is "A Kind of Pre-warning Police for Subway Train Conflicts" Law, the filing date is: the divisional application of the invention patent application on March 31, 2015. technical field [0002] The invention relates to a subway train conflict early warning method, in particular to a subway train conflict early warning method based on a robust strategy. Background technique [0003] With the increasing scale of large and medium-sized cities in our country, the urban traffic system is facing more and more pressure, and vigorously developing the rail transit system has become an important means to solve urban traffic congestion. The national "Eleventh Five-Year Plan" outline pointed out that large cities and urban agglomerations where conditions permit should take rail transit as a priority area of ​​development. my country is experiencing an unprecedented peak period of rail t...
