Abstract

Method for detecting the operating stand-by of a European train control system (ETCS) section comprises matching section imaging data to track-geometric measuring data. Preferred Features: The imaging data is subjected to a quality evaluation based on corresponding track-geometric measuring data.

Description

The The invention relates to a method for proving operational readiness ETCS (European Train Control System) route in terms of interoperability of localized Facilities, in particular for train control, command and signaling, where track image data is used to position the devices be placed.

According to Article 6, paragraph 1 of the EC Directive 96/48 from 2002 is for ETCS routes proof of operational readiness is required. This applies in particular the technical specification for the interoperability of the control - command and signaling subsystem trans-European high-speed rail system ETCS.

To This proof has so far used processes and rules that are based on Track map data is based on the operator of the ETCS route available to the system supplier be put. These planning documents are usually legally binding Paper form before. It has been shown that the plan documents often no represent sufficiently accurate image of the concrete route and partially inconsistent with each other. As a result, additional Track surveying by the system supplier is essential to consistency between the plan documents of the track operator and the actual Establish route topology. The required effort is disproportionately high, on the other hand, in the absence of an additional distance measurement implementation error can result only after the configuration of the local facilities can be clearly recognized on the track. At this late date However, all content and formal exams are already and Completed appraisals, so that the disclosure of these mistakes a new complete run through all engineering steps, d. H. from project engineering to implementation. Unfortunately, This engineering loop can only be done at a time, at which the project dates shortly before the conclusion and thus before delivery to the track operator stands. Thus, the implementation of the configured route segment data an incalculable risk in terms of proof of operational readiness. In case of significant deviations the underlying track data or their insufficient correction Due to punctual distance surveys, several engineering loops can be used to be necessary. But a pre-distance measurement does not necessarily lead to flawless plan documents, because of the enormous effort not all relevant points of the route can be recorded.

Of the Invention is based on the object, a method of the generic type indicate, with the additional Engineering loops can be reduced.

According to the invention Task solved by that the route image data with track geometry survey data be matched. Such track geometry survey data usually becomes from parent Bahnverwaltungsinstanzen held, as these surveying data for completely different Purposes, for example, for structural engineering Planning, needed become. These survey data are available in electronic form and can about one intelligent interface for loading the planning documents, d. H. track data of the railway operator, for the purpose of comparison, d. H. be used for verification of this route map data. This is too early Time an error correction of the submitted plan documents possible. Ultimately there is a reduction of additional Engineering loops. The for the configuration and implementation of required route image data can be over this way plausibility considerations interpolate. The risk of unrecognized errors in the plan documents is reduced. The engineering process can from the outset with qualitative Improved planning documents. It can be assumed be that the track geometry survey data independent of the routing image data of the plan documents were created because the parent Bahnverwaltungsinstanz as the owner of the track geometry surveying data predominantly is not identical to the railway operator, the plan documents created. The plan documents submitted to the system supplier almost an entrance examination by means of an independent Data source subjected. This makes differences very early recognized and can possibly by additional punctual inspection or Remeasurement very early be rectified. Very significant late effects, which only at Implementation of local facilities along the route show are avoided.

According to claim 2 it is provided that the route image data based on identified Deviations from corresponding track geometry survey data subjected to a quality assessment become. This quality rating can be automated and standardized. The proof of quality The route image data can be used to implement the requirements for quality and accuracy of the provided route image data according to UNISIG Subset 091 for warranty highest claims to SIL (Safety Integrity Level) 4 support.

The adjusted route image data and the track geometric survey data are used according to claim 3 for the implementation of the fixed facilities, the interoperability of the facilities is tested by means of operational test scenarios. By using the geometry data for testing the interoperability, together with the projected data, it is possible to prove the operational readiness of the ETCS route via an independent route, ie independently of the original plan documents.

The The invention will be explained in more detail with reference to a figurative representation.

The FIG. 1 shows a schematic sequence for proving readiness for operation an ETCS track.

Previously, only the route image data was used to prove the operational readiness 1 used. The project planning 2 the functionalities of localized facilities on the line, ie the field elements, after verification 3 and test 4 in the engineering process to implementation 5 performed, with errors in the route image data 1 could lead to problems regarding the interoperability of the field elements. Only successively, after passing through several engineering loops of the project planning 2 until the implementation 5 sufficient interoperability can be achieved. Only then could the release 6 ETCS track and commissioning 7 done by the track operator.

In order to avoid multiple engineering loops, according to the invention the track image data 1 using independently generated track geometry survey data 8th adjusted.

This is served by an intelligent interface 9 , The reconciled data becomes the configuration 2 and verification 3 used as well as the track geometry survey data 8th with operational scenarios 10 subjected to proof of operational readiness 11 according to EC directive 12 already before the implementation 5.1 is possible. Ultimately, the release 7.1 and commissioning 7.1 faster and more secure because the risk of an incalculable number of engineering loops is significantly reduced.
