During the Innotrans Exhibition to be held in Berlin on September 17-21, ETS will present ARCHITA his innovative mobile mapping survey system. The main configuration is dedicated to the rail, but the wide range of tools and the various different combinations, allow the use in any landscape o scope where a thorough investigation is required.
ETS ARCHITA Rail Mobile mapping system is a unique system consisting of various detection technologies: laser scanners, georadar, thermo-graphics image and high speed/resolution digital camera, placed on a service train. It allows to carry out the continuous activity (average speed 15-30 km /h) during the interruption of the railway traffic, without the need to remove tension, reducing the interference to the ordinary rail traffic. ARCHITA has allowed to get, in a single railroad transition, a series of functional information to the project’s. The main information obtained is: 1. Point cloud georeferenced of a gallery from which it is possible to obtain a very specific information about the object of the study; 2. Thermographic analysis with information about the conservation of the covering; 3. Georadar analysis with relative information about the condition of the ballast. In general, it was possible: Automatically obtain the track geometry (gauge and elevation) and verify the exact position respect to the point cloud; Pass the design template into virtual and check for any interference; Calculate the position of the TE contact line with respect to the iron plane and evaluate its possible interferences with the design template; Generate “xls” summary format with kilometric location of the tracing zones subject to interference (with coating and/or contact line), indicating their size and typology Therefore, on the basis of the analysis and the results obtained, RFI, in accordance with precise strategic guidelines, has been able to define and plan appropriate interventions to achieve the objective of adapting to the shape of the tunnel in question. In conclusion, the experience gained in the “mobile mapping” industry allows, therefore, to configure the mobile survey system as a valid alternative to the traditional geometry/topographic survey methods, which require extremely long-time cycles that are highly impacting on the railroad exercise. The union of different results, obtained from different instruments (laser scanner, georadar, thermography, High speed digital line/scan cameras) and configured in a single solution, therefore provide a knowledge of the state of play of the investigated work needed to support planning activities of maintenance and amortization of the entire infrastructure assets, providing for both ordinary and overtime. Further, the dual GPS antenna greatly improves the alignment of the detected trajectory, ensuring a millimeter precision. The system binds thermographic analysis to the geometric data recorded by the laser scanner, allowing integrated management in a single software. The system allows continuous radar explorations on long distances, investigating the conservation and conditions of the ballast and any anomalies present with an optimum depth resolution of 2m.
