Early warning method of subway train conflict

Abstract

The invention relates to a method for early warning of subway train conflicts, comprising the following steps: firstly generating a topological structure diagram of a rail transit network according to planned operation parameters of each train; then analyzing the controllability and sensitivity of train flow based on the topological structure diagram; Then, according to the planned operation parameters of each train, generate multi-train conflict-free running trajectories; then at each sampling time, based on the current running state of the train and the historical position observation sequence, predict the traveling position of the train at a certain time in the future, and then establish the The observer of train continuous dynamics to discrete conflict logic maps the continuous dynamics to the conflict state expressed by discrete observations; when the system may violate traffic control rules, it monitors the mixed dynamic behavior of the subway traffic mixed system, which is the control center Provide warning information. The invention rolls and predicts the trajectory of subway trains in real time, effectively warns of train conflicts, and improves the safety of subway traffic.

Description

technical field [0001] 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 [0002] 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 transit development. Some cities have shifted from line construction to network construction, and urban rail transit networks have gradually formed. In complex areas with dense rail transit network and train flow, the method of still adopting train operation plan combined ...

AI Technical Summary

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 congestion problem is solved by adjusting the key operating parameters in some areas of the transportation network through an effective monitoring mechanism, but there is currently no more accurate solution for the prediction of the trajectory of the subway train and the early warning of train conflicts.
