LOCOPROL

from Wikipedia, the free encyclopedia

Locoprol ( Lo w co st satellite based train location system for signaling and train pro tection for L was ow density traffic railway lines), a project to study the inclusion of satellite navigation by rail from Europe with the aim of using on routes with low train density. It is intended as an extension of the ERTMS train protection system. The partner project LOCOLOC examined the driver's cab signaling and speed control. LOCOPROL was funded from the EU's 5th Framework Program for Research . Alstom was responsible for project coordination .

Basics

Locoprol has adopted experience from other systems, such as Qualcomm's Euteltrac / OmniTRACS, which has been operating since 1991 for satellite-based fleet management, followed by APOLO (Advanced Position Locator), ECORAIL (EGNOS Controlled Railway Equipment) and parallel projects such as INTEGRAIL (2001-2003) by ESA . Just like GADEROS (GAlileo DEmonstrator Railway Operation System) for the investigation of satellite positioning in ERTMS (project partners INECO, TIFSA, Railways Safety, ERRI, Aena, GMV Sistemas, Sener, NSL), LOCOPROL was financed from the 5th Framework Research Program of the EU.

The project was supported by Alstom (Belgium), Honeywell Regelsysteme GmbH (Germany), INRETS (France), Alstom Transport (Italy), Trasys (Belgium), Alstom Transport (France), BPV (Germany), Septentrio (Belgium), Reseau Ferré de France (France), NMBS / SNCB (Belgium), Northern Jiaotong University (China), European Road Transport Telematics Implementation Coordination Organization SCRL (Belgium).

Continuation

The project officially ended in 2005, but the results were continued in other projects. Starting in 2006, ESA has also investigated the suitability of the Galileo (satellite navigation) for “virtual balises” with RUNE (Railway User Navigation Equipment) . and the UIC GEORAIL project has been dealing with the use of location systems in rail traffic since 2004. GIRASOLE (accompanied by the SNCF's GPS-LOC), GRAIL and M-TRADE, which ran until 2007, are then included in the EU's 6th research framework plan. In England, LOCASYS joined the LOCOPROL project, which examined further dependencies until 2009, and in Belgium the LOCOPROL pilot line was further expanded with a view to the TransLogisTIC project between 2007 and 2009 which examined the suitability in integrated transport. Finally, satellite-based systems are in use in rail traffic, for example in France - the Tr @ in-MD of the SNCF monitors the transport of dangerous goods and Gédéon of the SNCF allows freight tracking in the route network.

Similar projects are satellite-based train control with the Nationwide Differential Global Positioning System (NDGPS), which is to be developed in the USA by 2015 as part of Positive Train Control . The ERTMS Regional System from Banverket is also a cost-optimized variant of ERTMS for use on branch lines, which, however, still works without satellite positioning. For the 7th research framework program of the EU, the GRAIL-2 project is proposed by the GSA / ESA, which further investigates the integration of satellite positioning in ERTMS.

The research was continued in other projects, including GaLoROI and 3inSat. The eighth research framework program, alias Horizon 2020, includes further projects on satellite positioning with Galileo in rail transport. These include, for example, RHINOS and STARS.

Results

The results of LOCOLOC / LOCOPROL showed that satellite navigation in urban areas is severely restricted by the lack of visibility of satellites. In the project, algorithms were developed that could compare the satellite signals with a one-dimensional flat route map so that two satellites are sufficient for security. (Of the six satellites for a reliable EGNOS measurement, 3, in certain cases 4 satellites can fail). Nevertheless, the limits of the SIL4 safety criteria were not met (98% of the measurements outside tunnels were successful), but the test model was not conclusive for all system dependencies. The results have shown, however, that passive Eurobalises are necessary in the vicinity of stopping points in order to counteract the inadequate accuracy of satellite-based train location.

Since EGNOS certification for safety-of-life applications is still pending in the course of 2010, the results of LOCOPROL could subsequently be checked again in a non-prototype environment. Compared working at the North American Joint Positive Train Control program with two differential GPS receivers, connected to an inertial navigation system for bridging distances with poor satellite reception by dead reckoning (dead reckoning). The ITARUS-ATC developed with the Italian Ansaldo STS on the basis of the Russian KLUB-U train protection also uses satellite navigation (mostly GLONASS ) in connection with distance measurement via wheel sensors and inertia measurement for changes of direction in order to ensure a high level of safety for Russian passenger traffic - it is supposed to the 2014 Winter Games on the route to Sochi.

"," Therefore a full compliance to the railway safety CENELEC standards and best practices in the railway field is clearly not achievable to this research project. "," The signaling also validated the fact the use of, at least, passive eurobalises is necessary to mitigate the risk during train position initialization but also at singular location as points or in the vicinity of a railway station to counter the lack of accuracy of the satellite train positioning.
