Front-train identification method based on train-train communication

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...

Problems solved by technology

[0011] At the same time, due to the excessive functions of the ground equipment, it will also lead to the disadvantages of multiple configuration equipment, complex system interface and structure, and heavy dependence on the central equipment for train operation, as well as the resulting long construction period, complicated commissioning, and a wide range of faults. Problems such as high maintenance cost and difficulty in interconnection
