METHOD AND SYSTEM FOR MONITORING A POINT SYSTEM OF A RAILWAY NETWORK, AND POINT SYSTEM OF A RAILWAY NETWORK

Method for monitoring at least one point system of a railway network comprising the steps of placing several sensors in correspondence of said at least one point system; acquiring from said sensors current and voltage signals of a point machine during a maneuver; and segmenting the signals of the maneuver according to different predetermined phases of movement. Then extracting predetermined features from each segment; comparing the extracted features with a set of predetermined values which represent a healthy maneuver, thus obtaining a global indicator representative of the conditions of the maneuver at the point system; and comparing said global indicator with a failure threshold, and if it exceeds said failure threshold, detecting a failure in the point system.

Ground control device and wireless train control system

To provide a wireless train control system that can perform a stable operation. The wireless train control system controls a wireless-control compliant train following a wireless-control noncompliant train by a ground control device. A stop limit point of the wireless-control compliant train is set by a track circuit in which a tail end position of the wireless-control noncompliant train is present. By using a track-circuit state signal indicating that the track circuit is turned on or turned off and a time-element-added track-circuit state signal indicating turn-off at a timing delayed by a set time after the track-circuit state signal has indicated turn-off, when the track-circuit state signal indicates turn-off and the time-element-added track-circuit state signal indicates turn-on, it is determined that turn-off indicated by the track-circuit state signal is caused by the wireless-control compliant train that is a train itself being present, and the stop limit point is not updated.
