Problems solved by technology

[0009] However, such an approach is not entirely satisfactory
[0010] In fact, such an approach requires operator intervention, which can lead to accidents related to human error
Further, such methods involve long periods of stalling of rail vehicles, e.g. for as long as an operator intervenes, which is even more detrimental for driverless transport systems

Embodiment Construction

[0037] The railway vehicle 2 that circulates on the railway track 4 is as figure 1 shown.

[0038] The positioning of the railway vehicle 2 is carried out by means of a positioning device 3 comprising ground components and on-board components.

[0039] "Positioning" refers to calculating the extent of the position of the railway vehicle 2 on the railway track 4 .

[0040] For ground components, the railway track 4 is subdivided into a number of consecutive blocks 6 . Each block is identified by an identifier associated with the block's geographic location.

[0041] A plurality of secondary detection devices 8 , also referred to as on-track sensors, are placed along the railway track 4 . Each secondary detection device 8 is associated with a block 6 . For example, the railway track 4 comprises a first block 6A, a second block 6B and a third block 6C, each block 6A, 6B, 6C being associated with a respective secondary detection device 8 .

[0042] Each secondary detection me...

Abstract

The invention relates to a method and a related device for calculating the position range of a railway vehicle (2) on a railway track (4). In this method, the position range corresponds to the section of the track (4) between the front end and the rear end, and it is characterized in that the method includes the following steps: by the sensor (8) on the track to identify the block (6) of said railway track (4) occupied by said railway vehicle (2); sending the identifier of the occupied block (6) to a ground computer (12); and by said ground A computer (12) calculates a location range (S d ).

Description

technical field [0001] The invention relates to a method and related device for calculating the position range of a railway vehicle on a railway track, said position range corresponding to the track section between the front end and the rear end. Background technique [0002] The invention is applied in the field of railway safety, especially in automatic systems for controlling railway traffic. Such a system is, for example, a so-called communication based train control system (communication based train control system, CBTC system). [0003] Typically, for a railway vehicle that circulates on a railway track, the range of the vehicle's position on the railway track is determined by an on-board computer on the vehicle. The range of the vehicle's position is then sent, for example via radio waves, to a central computer on the ground. The computer on the ground is adapted to receive the range of positions of a plurality of rail vehicles and to control the movement or stoppin...
