PROCEDURE AND SYSTEM FOR THE IMPROVEMENT OF THE ASFA DIGITAL SYSTEM INCORPORATING VIRTUAL ASFA BEACONS, BEACON PROFILE AND TRAIN POSITIONING (MACHINE-TRANSLATION BY GOOGLE TRANSLATE, NOT LEGALLY BINDING)
ES2418929
Procedure and system to improve the performance of the asfa digital system without the need to introduce any modification in it, through the inclusion of "virtual" asfa beacons that substitute or complement the information of the physical asfa beacons, allowing control to continue to be carried out of temporary speed limitation even in the absence of physical asfa beacons. Any asfa physical beacon on the road with defective operation is identified, and a report of the same is generated, this information being sent, via radio, to the facilities located on the ground. This new concept of train circulation, is based on each mobile rail unit to store an updated digital map (profile of beacons on route) which include, among others, the geolocation and kilometric point of the asfa physical and virtual beacons, of circulation, speed allowed in the sections, etc. (Machine-translation by Google Translate, not legally binding)
It Include virtual ASFA beacons which replace or supplement the information of physical ASFA beacons located in the rail track, and especially those of temporary speed restrictions (LTV). The system increases the railway transport safety significantly. It gives accurate and updated information, at all times, that enables proper supervision of trains speed, depending on the signs and on particular conditions of each section, etc. Clearing potentially dangerous situations that may occur in the train circulation. In fact a large percentage of train accidents occur due to a detection fault of physical ASFA LTV beacons in track. It allows the detection of defective ASFA beacons and thus better maintenance of rail infrastructure, going from a corrective maintenance (once the fault occurred) to a predictive maintenance (based on the monitoring of certain characteristic parameters, to predict when the beacons will fail). The response time from breakdowns is reduced dramatically, it automates various processes related to operating of railway vehicles. The solution proposed in this patent is 100% compatible with the current ASFA Digital equipment. This solution allows to insert new functionalities in current ASFA Digital systems.
