Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0017] figure 1 It shows that an embodiment of the present invention provides a method for analyzing the cross-turning capability after a station based on the vehicle-to-vehicle communication train control system, including:

[0018] S11. Obtain the key points in the process of crossing and turning back after the train executes the station on the track. The key points include conventional key points and improved key points. A safety tracking position point is set, and a preset safety tracking position point on the turning-out track and close to the side of the upward track, and a preset safety tracking position point on the turning-in track and close to the side of the do...

Abstract

The embodiment of the invention provides a method for analyzing a post-station cross foldback capability, which comprises the following steps of: acquiring key points in the post-station cross foldback process of a train on a track; and under the control of a vehicle-to-vehicle communication control system, acquiring the driving time lengths between key points when foldback vehicles respectively execute post-station cross foldback according to a preset driving sequence, generating a driving time sequence diagram of each foldback vehicle according to the driving time lengths between the key points, acquiring a foldback interval formula group according to the driving time sequence diagram, according to the foldback interval formula group, obtaining the analysis result, the vehicle-to-vehiclecommunication system is adopted to independently control switch resources, communication links are reduced, accurate vehicle tracking is achieved, the post-staion cross foldback time interval is shorter than that of a CBTC system, stronger post-station cross foldback capacity is provided, decision support for the planning and designing of a newly-built line is achieved, the design of a station shape and the matching of lines can be guided, and the requirement of adjusting the operation along with the change of the a passenger flow volume is satisfied.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a method for analyzing the ability of crossing and turning back after a station based on a vehicle-to-train communication train control system. Background technique [0002] The rail transit train control system widely cited at present is the CBTC signaling system. The CBTC system takes the control of train operation by ground equipment as the core, and mainly relies on the interlocking CI to arrange routes for trains to prevent route conflicts. The zone controller ZC calculates the safe operating position of the train movement authorization to prevent dangerous situations such as collisions. [0003] Constrained by the CBTC system control mode and backward technology, in order to ensure safety, a certain operating efficiency has to be sacrificed. The direct performance is that the ability to turn back after the station is low, and the ability to turn back after the statio...
