System And Method For Controlling The Integrity Of A Railway Convoy, And Railway Convoy Comprising Such System

Abstract: System (100) for controlling the integrity of a railway convoy which comprises a 5 driving car (1) and a plurality of cars (3, 5, 7, 9, 11, 13) disposed in sequence behind the driving car, comprising: - a plurality of wireless transceivers (12, 14, 16, 18, 20, 22) at least one of which is installed on each associated car; - - an electronic control device (10), suitable to be installed on the driving car, which 10 initiates a counting of the cars by sending, towards the following adjacent car (3), in a wireless manner, a counting signal (SC) which includes an updatable value indicating the number of cars currently counted. Responsive to the counting signal (SC) received, each wireless transceiver sends back towards a transceiver of the preceding car or to the electronic control device 15 a signal (SOK) confirming the presence of the car on which it is installed, updates the current value by adding the count of its associated car, outputs towards a transceiver associated to the following car a corresponding counting signal (SCUP) containing the updated value. Each transceiver sends back towards the electronic control device, a counting-20 closing signal (SFC) which includes the current value as ultimately updated by itself if it does not receive the confirmation signal (SOK) after an interval of time is elapsed from when it outputs the counting signal. The electronic control device calculates the length of the railway convoy based on the counting-closing signal received and generates an alarm signal (SA) if the 25 calculated length does not correspond to a predefined value. 21
