Improved automatic train control system and corresponding method

Abstract

The invention provides an improved automatic train control system and a corresponding method. This system includes a ground ATC and an on board ATC, which is switched from an active mode toward a standby mode and vice versa by a wake-up unit. In the standby mode, only the following components remain powered: odometry means; a main computer; a radio communication means between the on board ATC andthe ground ATC; the wake-up unit. The main computer is programmed so as, in the standby mode, to verify that the movement of the train measured by the odometry means from the switching from the activemode to the standby mode is zero and, in the affirmative, to send the ground ATC an instantaneous position of the train using the radio communication means.

Description

technical field [0001] The present invention relates to an automatic train control system utilizing a communication-based train management type, in particular an automatic train control system of the CBTC type (communication-based train control, as defined by the standard IEEE 1474). More particularly, the present invention relates to components of such systems onboard a train. Background technique [0002] The term "train" should be understood herein broadly as a guided vehicle, ie any type of vehicle that travels along a track, such as a train, subway, streetcar, or the like. [0003] It is known to utilize signaling systems to manage the travel of trains on a railway network, including automatic train monitoring systems, interlocking systems, and automatic train control systems. [0004] The Automatic Train Monitoring (ATC) system is implemented in the operating unit. It consists of different subsystems capable of assigning a path to each train and requesting to open a ...

Problems solved by technology

[0022] This prior art solution has the disadvantage of requiring the installation of a large number of radar installations along the tracks of the railway network

So for cost and maintenance reasons it is limited to garage tracks

[0023] Furthermore, comparing radar images is complex and prone to many false alarms, which correspond to detection of train movement when the train actually remains stationary, or failure to detect specific features associated with train movement or disengagement. event
