Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0045] like Figure 6 As shown, a train relocation method based on speedometer and trackside loop includes the following steps:

[0046] Step A: Select the crossing point of the trackside circular line;

[0047] Step B: Obtain the static parameters of the intersection of trackside circular lines;

[0048] Step C: Obtain the dynamic information of the intersection of the speedometer and the trackside circular line;

[0049] Step D: judging whether the cu...

Abstract

The invention relates to a train repositioning method based on a speedometer and a trackside loop line. The method comprises the following steps of A, selecting a trackside loop line intersection point; B, obtaining static parameters of the trackside loop line intersection point; C, obtaining dynamic information of the intersection point of the speedometer and the trackside loop line; D, judging whether the current train position is at a platform; and E, completing train repositioning based on the speedometer and the trackside loop line. Compared with the prior art, the method has the advantages of high positioning precision, high repositioning reliability and the like.

Description

technical field [0001] The invention relates to a train positioning technology, in particular to a train repositioning method based on a speedometer and a trackside loop. Background technique [0002] The on-board controller is the core controller for train safety monitoring and operation management. For trains in normal operation, in the automatic driving mode, it is necessary to be able to correctly stop on the platform to ensure that the alignment accuracy of the doors and platform doors is within a certain range. [0003] At present, most of the signaling systems in China, the on-board controllers rely on beacons for relocation and correct parking on the platform. There are also some signal systems. The on-board controller is based on RFID and repositions at the last stop moment to complete the correct stop of the platform. At that time, the two existing positioning methods still had problems such as low positioning accuracy and poor reliability. Contents of the inve...
