Contrôle de vitesse par balises

Contrôle de vitesse par balises (abbreviation KVB ) is an automatic train control system in the network of SNCF in France. Also in London's St Pancras Station KVB was installed because the there -ending high-speed line HS1 completely based on French technology. The system consists of track-side beacons including signal and computerized equipment. Is an overlay system in which the signal from the conventional signaling systems will be superimposed. The system is derived from the Swedish ATC ATC system.

Implementation

The data transmission is between passive track side beacons (two to nine pieces per signal) and an on- board antenna underneath vehicle which also supplies the beacon with energy when passing. KVB can be completed by a continuous transmission to achieve a fill functionality (similar to EUROLOOP ).

KVB monitored:

  • Line speed, including permanent and temporary speed restrictions
  • Halt
  • Dynamic braking profile
  • Speed ​​restrictions

If KVB discovered that monitored values ​​have been exceeded, then the driver is warned. Reacts this not the warning, then the emergency brake of the train.

KVB also controls the shunting, the transitions to other systems (Transmission Voie - Machine), takes over the switching of radio channels, the opening of the main switch, the lowering of the pantographs, the side selection for doors opening, the selection of the height of the steps, the command of air tightness through tunnels or across areas with chemical risk.

KVB regard ETCS out as a national class -B system.
