Abstract: When an event prevents a train from moving along a route in a nominal direction, this method makes it possible to cause it to circulate in an opposite direction by: selecting (120) an origin zone and an output signal; drawing (130) a pseudo-route on the successive zones between the origin zone and the output signal; opening (140) the pseudo-route by associating a sub-route with each zone, corresponding to the reservation of said zone for said train; informing (150) the train that it must circulate in the opposite direction; determining (160) a movement authorization for the train from sub-routes that are open and a list of obstacles that is updated regularly; sending (180) the movement authorization to the train, the determination (160) and transmission (170) steps being iterated until the train crosses the output signal.

Abstract: Disclosed is a method, implemented in a supervision system for trains of the “communication-based train management” type, which includes the steps, carried out by a zone controller, including: during nominal operation, periodically saving an image of a current operational situation on an external memory; and, after a downtime period and rebooting of the zone controller: establishing an image of the operational situation after rebooting; recovering, from the external memory, the most recent saved image as image of the operational situation before failure; collecting information on the crossing of borders of the zone associated with the zone controller during the downtime period; and verifying the coherence of the image of the operational situation after rebooting from the image of the operational situation before failure and crossing information.

Abstract: The invention relates to a method for controlling the circulation of vehicles in a network controlled by a control system managing the circulation of communicating vehicles according to a first mode, the first mode managing the movement of the communicating vehicle toward the end terminal of a first section in which a non-communicating vehicle has been detected by implementing a discrimination step eliminating any protection zone located the moving vehicle, when a distance between the communicating vehicle and said end terminal is smaller than a threshold, the method comprising switching into a second mode, when the communicating vehicle enters the first section, the second mode inhibiting the implementation of the discrimination step at least in the first section.

Abstract: In a gyroscopic system, a vibrating gyroscope is controlled in gyrometer mode in a control loop. The control loop corresponds to at least one current control for an operating parameter. In the control loop, a modified control to be applied to the gyrometer for said operating parameter is obtained (11) by introducing a sinusoidal interference into the current control. Then, the modified control is applied (12) to the gyrometer as the current control. A resulting measurement value (13) is determined. A sinusoidal interference (14) is calculated as a function of said measurement value. Lastly, on the basis of the measurement value, it is decided (15) whether to repeat the previous steps on the basis of the sinusoidal interference last determined.
