Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing.

[0012] The point-type ATP protection method under the degraded signal system of the present invention, when the communication between the train and the trackside is lost, or the system switches into the backup mode, the degraded signal system provides an effective degraded operation mode, which combines the characteristics of the continuous ATP mode. Formula ATP mode. The train is provided with safety interval protection by the signal interlocking subsystem. The on-board equipment obtains the point-type movement authorization by receiving the interlocking information sent by the transponder or beacon of each signal machine, and calculates the front signal machine according to the principle of road blockage and the position of the train. The status, speed limit information, safe parking point, non-safe parking point, target parking point and the distance from the target park...

Abstract

The invention discloses a point-type ATP protection method achieved under a degradation signal system. The method comprises the steps that under the degradation signal system, on-board equipment of a train obtains point-type moving authorization by receiving interlocking information sent by transponders or beacons of signal machines arranged on a track, the state of the signal machine in front of the train, speed limiting information, safe parking points, non-safe parking points, a target parking point and the distance between the train and the target parking point are obtained through calculation according to the advancing obstruction principle and the train position, and then a dynamic target speed curve is calculated in real time according to the information and informed to a driver through a man-machine interface. According to the method, the vehicle distance is decreased, and the optimal continuous speed curve is provided for the driver.

Description

technical field [0001] The invention relates to the field of rail communication. Background technique [0002] When the communication between the train and the trackside is lost, or the system switches to the backup mode, since the on-board equipment cannot know the access authorization information transmitted by the trackside equipment, in the prior art, the fixed block mode divided by the signal machine is generally used, and the driver In point mode, speed limit driving is performed according to the stepped speed curve. Its disadvantages are: in point trains, the distance between trains is large, drivers can only rely on their own experience to drive according to the stepped speed curve, and cannot drive according to the optimal continuous speed control curve, thus affecting the operating performance of point trains. Contents of the invention [0003] The purpose of the present invention is to provide a point type ATP (train automatic) protection method under a degrade...
