Example Embodiment

[0044] In order to facilitate the understanding of the embodiments of the present invention, several specific embodiments will be taken as examples for further explanation and description in conjunction with the accompanying drawings, and each embodiment does not constitute a limitation to the embodiments of the present invention.

[0045] At present, with the continuous development of satellite navigation technology, sensor technology and wireless communication technology, it has become possible to directly exchange information between trains and trains during train operation. At the same time, the train control system will be based on the traditional "vehicle-ground-vehicle" communication structure. Transform into an interactive communication mode of "cars ahead, ground, and cars behind". Using the electronic map of the train running line information, the on-board equipment can already calculate the driving permit autonomously based on the acquired information, and complete the ...

Abstract

The invention provides a front-train identification method based on train-train communication. The method includes the steps that when a train gets in a station, or is driven in an interval, a train-mounted management unit of the train receives and stores all train operation information tables sent by a ground management unit; through the train-mounted management unit of the train, distance valuesbetween the train and all trains in the train information tables are computed through an electronic map according to route information of the vehicle, and a front train of the train is determined according to the distance values between the train and all the trains in the train information tables. According to the front-train identification method based on train-train communication, limitation that a traditional train control system collectively controls driving through ground equipment can be broken through, the front train is automatically identified through the train, a driving end point is determined, driving permission information is more accurately and dynamically updated, and the delay problem of an existing system is solved; various emergencies and various scenes of the driving process can be more rapidly and accurately responded, and safe and efficient driving is guaranteed.

Description

technical field [0001] The invention relates to the technical field of train operation control, in particular to a vehicle-to-vehicle communication-based recognition method for a preceding vehicle. Background technique [0002] At present, in my country's existing railway train control system, the train operation instructions are mainly given by the ground equipment, and the on-board equipment is only responsible for the functions of train overspeed protection according to the operation instructions. The ground equipment has many integrated functions and complex interfaces, which increases safety hazards. . [0003] Taking my country's current CTCS-3 train operation control system as an example, the train management mainly relies on the RBC (radioblocking center, ground wireless blocking center) to integrate information transmitted by other ground equipment (such as: interlocking, temporary speed limit server), and communication with the on-board The equipment generates train...
