Train tracking capability determination method based on relative speed tracking model

Abstract

The invention provides a train tracking capability determination method based on a relative speed tracking model, and the method comprises the following steps: constructing the relative speed tracking model based on a preceding train and a backward train, and enabling the relative speed tracking model to consider the emergency braking distance of the preceding train in a process that the backward train tracks the preceding train; and calculating the relative speed tracking capability according to the relative speed tracking model. The problems that under the relative speed tracking model, there is no determination mode for the relative tracking capability of various tracking scenes of the actual operation of the train, the relative tracking capability cannot be compared with the relative tracking capability of the existing relative position tracking model, and technical support cannot be provided for subsequent train system optimization are solved.

Description

technical field [0001] The invention belongs to the technical field of rail transit operation control, and in particular relates to a method for determining train tracking capability based on a relative speed tracking model. Background technique [0002] The rail transit train control system is a closed-loop control system with two-way communication formed by the train, the ground (including the cable transmission network) and the wireless network between the train and the ground. The same below) sends control information to the train, and at the same time, the train can send its own position information, speed information and other information required by the ground equipment to the ground equipment in real time. The vehicle-ground wireless communication network is the wireless communication between the train and the ground equipment. The transparent transmission channel realizes the real-time transmission of vehicle-ground two-way information. [0003] The equipment on th...

AI Technical Summary

Problems solved by technology

Therefore, when the distance between trains is encrypted, the technical shortcomings of the existing relative position-based tracking methods are obvious, especially in the case of urban rail transit with small intervals, the ability of trains to operate in intervals and turn-back stations can no longer meet the existing operating interval requirements

[0007]2. The control method is not fully integrated with the actual operation of the train

The existing relative position tracking method does not conform to the actual train operation, so the safety distance protection calculation of the following t...
