SYSTEM AND METHOD FOR LOCALIZING A RAILWAY VEHICLE TRAVELLING ALONG A RAILWAY LINE POWERED BY A CATENARY, AND RELATED RAILWAY VEHICLE

摘要

A system (100) and a method (200) for localizing a railway vehicle (1) travelling on a railway line (10) which is powered by a catenary line (2) comprising a current-conducting wire (3) supported by a plurality of spaced apart catenary poles (4), wherein at least one sensor (110) is installed on-board of the railway vehicle (1) and is configured to provide to a control and processing unit (140), while the railway vehicle (1) is travelling along the railway line (10), first signals (S1) indicative of the actual value of a first parameter detected related to said current-conducting wire (3). The control and processing unit (140) is configured to calculate, based on the first signals (Si) received, a second parameter indicative of a catenary pole (4) possibly detected along the railway line (10). A plurality of devices (120) are installed on board of the railway vehicle (1) and are suitable to provide to the control and processing unit (140) second signals (S2) suitable for identifying the catenary pole (4) possibly detected; and wherein the control and processing unit (140) is further configured to univocally identify the catenary pole (4) possibly detected based on the second signals (S2) and to calculate the actual position of the railway vehicle (1) along the railway line (10) based on the univocally identified catenary pole (4).
