Subway train collision early warning method

Abstract

The invention relates to a subway train collision early warning method. The subway train collision early warning method comprises the following steps that a topology structural chart of a track traffic network is generated according to planned running parameters of trains; controllability and sensitivity of train flow are analyzed based on the topology structural chart; a multi-train non-collision running track is generated according to the planned running parameters of the trains; the running positions of the trains at some time are predicted at each sampling time based on the current running state of the trains and the historical position observation sequence, an observer from the continuous dynamic state of the trains to the discrete collision logic is established, and the continuous dynamic state is mapped into the collision state expressed through the discrete observation value; and when it is possible for a system to violate the traffic control rule, the hybrid dynamic state of the subway traffic hybrid system is monitored, and alarm information is provided for a control center. The subway train track is predicted in a rolling and real-time manner, an effective early warning can be achieved for the train collision, and the safety of subway traffic is improved.

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 ...

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.
