Problems solved by technology

[0007] The main purpose of the present invention is to solve the problem that in the prior art, the train tracking in the CBTC mode is a single-vehicle operation mode. The communication process realized by it is vehicle-ground communication, and it is difficult to realize vehicle-vehicle coordination, resulting in excessive tracking distance between trains and insufficient line use. Insufficient and serious technical problems of resource waste, a method, system and device for train safety protection based on coordinated formation are provided

Embodiment

[0047] This embodiment provides a train safety protection method, system and device based on coordinated formation.

[0048] like figure 1 As shown, under the premise of vehicle-to-vehicle communication, after the train’s own speed measurement and positioning, the train shares its own speed, position and current operating status with the adjacent vehicles in front and behind through communication means, such as figure 1 Shown; the rear car directly tracks the safe rear position of the front car according to the comprehensive information;

[0049] In this embodiment, the train communication mode is designed to be adjacent train communication, that is, the train can maintain communication with its preceding and following vehicles (if there is a leading or following vehicle), then the communication matrix is ​​as follows figure 2 shown.

[0050] like image 3 Shown is the bicycle tracking principle in the design formation of this embodiment. The first train in the group (i=1...

Abstract

The invention relates to a train safety protection method and system based on coordinated formation. In the solution of the present invention, there is communication between the trains, and the coordinated formation of vehicles can be realized, so as to expect to obtain a smaller train tracking distance. The scheme of the present invention adopts the way of vehicle-to-vehicle communication to control the coordinated operation of the trains, thereby canceling the actual couplers linking the trains and replacing them with virtual links, which avoids the physical contact between the car bodies and also avoids the wear and tear of the car bodies. At the same time, the number of marshalling can be largely independent of the physical scale, and the number of marshalling is theoretically unlimited.

Description

technical field [0001] The invention relates to a train safety protection method and system, belonging to the field of rail transit, in particular to a train safety protection method and system based on coordinated formation. Background technique [0002] With the rapid development and in-depth application of the rail transit signal and control profession, the rail industry demand market has put forward higher requirements for all aspects of train technology, including the formation and operation of trains. The current communication-based train control Communication Based Train Control (CBTC) operation mode based on the mobile block tracking mode has greatly shortened the tracking distance between trains compared with the fixed block, and uses the train-ground two-way real-time communication to monitor the train running status. Guard with line location. The application of train reconnection technology has also effectively increased the line operation capacity. However, the...
