Definitions

  • the invention concerns a method and an apparatus to verify, modify, manage and plan superstructures for underground, tram and railway lines and similar, as set forth in the main claims.
  • the invention refers to a method and an apparatus to collect and memorize in a single relational database all the data, detected over time, relating to the state of the lines involved, together with the design information, and information on the maintenance operations already carried out and on the use of the lines themselves, in order to allow the analysis and graphic representation of the current state of the lines and its evolution, and also to study the phenomena of wear and the performance results by means of processing models, employed in the relational database.
  • the European patent application EP-A-095349 in the name of the present Applicant, disclosed a method and apparatus to detect anomalies in rails, providing detection means able to detect the geometric and wear parameters both of each rail inspected and also of the two rails of the same track, and to transform these parameters into digital data which are memorized, at least temporarily, in a first memory.
  • the nominal or design values of the geometric parameters are memorized in a second electronic memory and an electronic processor is associated with the detection means and to the two electronic memories in order to compare the digital data detected with the nominal values.
  • a third memory is provided to memorize the data relating to the pre-set tolerances of the above-mentioned nominal values.
  • the electronic processor is able to display the data relating to the tolerances, together with the result of the above-mentioned comparison in order to show whether any one of said digital data is within or outside the pre-set tolerances.
  • US-A-5,867,404 discloses a method and an apparatus for monitoring defects in a railway with a computer system, wherein the method includes the steps of determining positional data and status data for a railway; comparing historical status data to the status data to determine a defect for the railway, the defect having a defect type; displaying an image of a particular geographic area on a display that includes a location corresponding to the positional data; determining an icon associated with the defect type; and displaying the icon associated with the defect type on the display.
  • the treated data and information are not sufficiently precise, because they are based on information acquired by a data acquisition module through an accelerometer and a tilt sensor both disposed on board of the rail car and which provides only car movement information.
  • the data acquisition module comprises also a global positioning sensor (GPS) able to provide location information of the rail car with an insufficient positional accuracy of about 15 meters under non-steady state conditions.
  • GPS global positioning sensor
  • the main purpose of the invention is to achieve a method and an apparatus which allow to know the real situation of the tracks of a line, or of a network of lines, point by point over its whole extension, no matter how great, with reference to the exact position on the layout, and to be able to prepare a maintenance program which will take into account the priorities of intervention, especially according to working safety.
  • another primary purpose of the invention is to achieve a method and an apparatus which will allow to increase the reliability and safety of the installations, and also the travelling comfort for the passengers, and to reduce to a minimum the vibrations which, as everybody knows, have negative effects on the buildings and works near the lines.
  • Another primary purpose of the invention is to achieve a method and an apparatus which, thanks to the processing models implemented or able to be implemented in the relational database, allow to make a study of the typical phenomena of wear, with regard to the parameters which influence the origin and development thereof, in order to be able to program and put the necessary technical devices into operation to reduce them.
  • a further primary purpose of the invention is to achieve a method and an apparatus which will allow to optimize the maintenance operations over the entire network of lines concerned, and consequently to reduce the costs of said operations, since it will be possible to prevent them from being carried out at random, or at points or in sections which do not really require it, or not as a priority.
  • Equipment to diagnose and detect the various data are of a conventional type, for example as described in the above-mentioned EP-A-0953491, and are able to acquire, in dynamic phase along the lines, all the raw data (acquisition on-line), which are subsequently processed on the ground, in off-line mode, by the apparatus and the method according to the invention.
  • the architectural hardware of the apparatus according to the invention has been designed and perfected according to the particular structure of the data to be analyzed and to be able to make available, also to third parties, the technical data processed, which can thus facilitate and optimize the planning of maintenance to existing installations, and also to design new railway installations, with the appropriate tramway type implementations.
  • the apparatus according to the invention is completely modular, that is, it allows to initially install only those devices or equipment which are necessary for a given line or network of lines, leaving the possibility open of any other addition or subsequent expansion.
  • the apparatus comprises a main electronic processor (server) where the historic data archive is maintained by means of a relational database, which contains the following information stored in historic form, with the spatial resolution of at least one datum for every metre of the line:
  • relational database it is also possible to insert data relating to the vibrational-acoustic detections to correlate them with those relating to geometry, wear, waving and suchlike.
  • the main processor is able to allow the combined analysis and representation of all sizes.
  • the main representations include:
  • Each of the representations can be activated by means of sensitive areas actuated by keyboards or by means of a movable pointer (mouse), so that it is possible to access, easily and immediately, detailed data, accessory information and photographic images, and also to show the relations between the graphics represented.
  • a movable pointer mouse
  • the data detected by the acquisition equipment, on each line like the geometric data (gauge, super-elevation, skew, longitudinal and transverse alignments, wear on the rails in the transverse section, longitudinal profile of the rail wear, amplitude of the waving wear of the rails, traversing height and wear of the contact wire of the aerial network supplying electricity), waving and wear, are transferred to the relational database with resolution, precision and coherence of the position where they are detected, so as to allow the historic analysis and the correlation of the data detected and the design data which are already memorized in the relational database.
  • the transfer of the data detected, from the detection equipment to the relational database can take place with any conventional means, either by means of removable magnetic supports (floppy disk, JAZ disks or suchlike) or on-line.
  • the data detected and their processing allow to construct, more easily and in a much more reliable manner than has ever been possible until now, maintenance programs for the installations, to draw up estimates for the purchase of materials and stocks of material, to compile periodic management budgets, for example annual or long-term.
  • the relational database thus set up also allows to use the data memorized therein in numerical form, in order to study the typical phenomena concerning fixed installations, their evolution over time and their correlation with the different parameters of the line.
  • This application is very important in order to develop, according to the experience acquired and the quantity and quality of the data available, plans for new systems of superstructures which will take into account the need to reduce pollution from vibrations and from noise.
  • the method according to the invention provides that electronic files of a standardized format are created, according to set fields, so that they can be imported directly into the database.
  • the data files can use other formats, for example corresponding to those used by data-acquisition systems already in existence before the apparatus according to the invention, for which a dedicated pre-processing and import function exists.
  • an apparatus 10 to verify, modify, manage and plan superstructures for underground, tram and railway lines and suchlike comprises a main electronic processor (server) 11, which in turn comprises a double central processing unit (CPU) 12, for example 500 MHz, a Read Only Memory (ROM) 13 in which the management programs of the CPU 12 are memorized, a first Random Access memory (RAM) 14 of the dynamic type, for example 640 megabyte (MB), a mass Random Access Memory 15, consisting for example of a large capacity "hot swap" disk, for example 36 gigabyte (GB), expandable to 128 GB, a tape unit 16, for example of the 24 GB DAT type, and a JAZ type disk unit 17, for example 2 GB.
