Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 43 / 76 Fig. 4-20 –Advanced Settings window • The Ground type field enables y ou to activate the Rough terrain option if necessary. When this option is activated, the radar data are temporarily saved on the selected Device during the acquisition phase. You can even select an external Device such as a flash memory to temporarily save the data during the acquisition p hases. This option is recommended when the ground conditions are particularly rough, and when you may find that saving the data during the acquisition phase becomes critical due to the high number of vibrations in the system. • In the Measure unit field, y ou can choose the measurement units to be applied to the radar map visualized in real time. The alternatives are m/cm and foot/inch • In the Wiggle sweep field, you can select the parameters for visualising the acquired data in real time in Wiggle mode; o Scale represents the signal amplification (intended as the number of pixels into which the -10V a +10V vector scale is mapped), o N. trace represents the “x” interval of the viewed traces (i.e. that one sweep is viewed every “x” traces), o Trace offset is on the other hand the representation interval between adjoining traces (i.e. also in this case the number of pixels) o Default Buttons saves the p reset settings as the default configuration. • In the Swap axis field, you have the choice of modifying the vertical scale of the radar map by setting the value in m or nsec • In the Gain application field, y ou can choose to view the radar map acquired in real time with or without gain applied • In the Background removal field you can set the Clear_x application for the acquired radar maps. • In the Display enable you can activate the display mode of the radar section during acquisition phase.

The following acquisition parameters can be selected from the window shown in Fig. 4-28: i. File prefix: this consists of two fields which you can fill as you wish. These fields form part of the scan identification (for example you could use the initials of the street name). These two characters, positioned after the first character which is either L or T deriving from the next cho ice (see the following point), make up the second and third of the 8 characters that identify the name of each single section. ii. The button allows you to open a virtual keyboard you can use to edit the scan coordinate values.
IDS Ingegneria Dei Sistemi S.p.A. Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 48 / 76 Fig. 4-28 – Acquisition Parameters Window iii. Marker 1 step: this field rep resents the distance between two reference lines marked on the site. The default value is 10 m. This function allows you to realign the radar sections to compensate for any distance variations with respect to the data acquired with the position sensor wheel. This realignment is performed according to the value set in the Marker 1 step box. This setting is typically used for realigning longitudinal scans. If you set the marker with a sp ecific p osition and then p ress the button shown in Fig. 4-29, contained in the window shown in Fig. 4-31 at a distance of ± 20% either before or after this assigned point, the Pos. Marker will be transformed into a User Marker when the file is saved (see Fig. 4-31 and point 3 of Par. 4.6). Fig. 4-29 – Pos. marker button iv. Longitudinal/Transversal – Inverse direction: this field allows you to select the scanning direction of the radar section about to be acquired. When filling in this field, remember that Longitudinal (L) means the scans is performed parallel to the zero referen ce line (T axis), while a scan perpendicular to this line is called a Transversal scan (T) (see Appendix A). The Inverse direction field allows you to perform a T/L scan in the opposite direction, i.e., moving in a
IDS Ingegneria Dei Sistemi S.p.A. Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 49 / 76 decreasing coordinate direction. In any case, you must return back to the same starting axis used for the forward scan. v. Coordinate (m): This field allows you to insert the values of the set T or L co-ordinate. R emember to indicate if a coordinate is negative. Check the current T or L coordinate on the site and insert it into the relative field. Remember that, desp ite the actual dimensions of the antenna trolley, it is represented in the Cartesian reference system by a single point that corresponds to its centerpoint. The position of this point varies depending on the array configuration that has been set. When moving the antenna trolley, make sure the centerpoint is on the scan line, at the defined coordinate.  Coord. value: insert the value of the coordinate to be maintained constant during the scan in this field.  Coord. Step: this field contains the step value that is added automatically to the current value when a scan is finished , leaving the system ready to start the next scan. The preset value = 2 m between scans. For example, if a longitudinal scan has been chosen and it starts from a point with coordinates T, L = 0;+2 m, the following values must be set: • Longitudinal; • 2 in the Coord value field; • 2 in the Coord. Step field. Once the scan is finished, the coordinate of the L v alue is automatically positioned on the value 4. ! BE CA REFUL The Antenna array may only be moved in one direction. It may only be pulled or pushed in the direction of increasing scanning coordinates, the only exception being when the Inverse Direction field is activated. vi. Scan Offset (m): each radar scan is characterised by an initial L and/or T co-ordinate Therefore, once you have inserted the starting point co-ordinate for the investigation (“coord. value” in Fig. 6-9) as a function of the type of scan, the other reference co-ordinate must be defined in the “Scan Offset (m)” field. There are two alternatives for this operation:  Select “With 1st Marker 1 step”: this selection automates the insertion of the second L or T co-ordinate when the antenna array crosses the zero line starting from a negative co-ordinate. This procedure is normally used when there are many irregularities on the site such as parked cars, indents
IDS Ingegneria Dei Sistemi S.p.A. Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 50 / 76 in the pavement, etc. In these cases, it can be very time consuming to calculate the distances each time as described above and is more convenient to select the With 1st Marker 1 box after having just set the initial L or T co-ordinate. The system automatically reco gnises the path performed in the negative portion and automatically associates the negative starting co-ordinate to the last L or T co-ordinate. For example, for the case of the Transversal scans shown in Fig. 4-30, first we select the scan type (in this case Transversal) in the “Scan Settings” window (Fig. 4-28). Then we set the current value of the T co-ordinate (2m in this case) in the “Coordinate (m)” field; finally, we activate the “With 1st Marker” option in the “Scan Offset (m)” field. In this way, the acquisition starts in the negative L p ortion, and when the centerpoint of the antenna trolley passes across the zero line, the M arker 1 button has to be pressed. The trolley is then pushed to the end of the scan. When the stop acquisition button is pressed, the system automatically associates a negative co-ordinate to the initial portion of the file of the scan that has been performed  “On L/T coordinate” selection In this case, you have to manually measure the value of the co-ordinate corresponding to the centerpoint of the antenna array with resp ect to the reference system selected previously, and insert it into the active field. For example, if y ou have to perform a transversal scan starting from the co-ordinate T=2 and L=2, you must set the type of scan to Transversal and then set the actual value of the T co-ordinate (e.g. 2 m) in the “Coordinate (m) ” field. Next, activate the “L coordinate” in the “Scan Offset (m)” area, setting it to 2 in this case. The scan can now be performed. ! BE CA REFUL In “With 1st marker 1 step” mode, the antenna system must be moved at least 20 cm after having pressed the Pos. Marker button shown in Fig. 4-29 before pressing the stop button; otherwise the section cannot be viewed by the elaboration SW.

Press the button in the window shown in Fig. 4-27 and start to move the trolley along the desired path (always in the same direction). The results of the single sections will start to appear in real time on the monitor in a window dedicated to channel 1 (see Fig. 4-31). The active channel is indicated with a red box in the sweep window. When a window is completely filled, the data will be written over from left to right and you will notice that the content of the radar section changes line by line. When the system passes across a possible utility or a radar target of any type, typical hyperbola shaped figures will appear with variable contrast in the depth direction corresponding to the impulses received. The presence of targets can be detected by comparing these figures, window by window, however, it is easier to perform this operation during the processing phase. The distance travelled by the trolley (Distance:….m) is shown above the radar map in real time, the depth is expressed in meters (m) on the left y axis while the time delay expressed in nanoseconds (ns) is given on the right y axis as indicated in Fig. 4-31. To visualize another acquired channel in real time, you can click on the small window of the signal corresponding to the desired channel.

IDS Ingegneria Dei Sistemi S.p.A. Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 55 / 76 ! NOTE Remember that data is grouped by scans, i.e. a group of radar sections relating to a single passage of the radar trolley. Any group of radar sections can be visualised from a given scan. You have a list of names of saved scans available. The following nomenclature rules apply for the scans: 1. the scan file names have 8 characters and have the *.dt extension before the data are processed; 2. the filename is derived as follows: • 1st character L or T depending whether the scan is longitudinal or transversal, • 2nd –3rd character can be chosen by the user, • 4th character * = channel number used • 5th –8th characters make up the progressive number of the scan within the survey. The first acquired file has the progressive number 0001, so for example, the name LMA*0012.DT is the name of the twelfth scan, performed in the longitudinal direction and contains unprocessed data. Each channel has its own corresponding data file. 4.7 Operating in review mode You can perform various operations on the acquired data.

Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 62 / 76 APPENDIX A - MECHANICAL REQUIREMENTS FOR THE INSTALLATION OF SRS SYSTEMS ON BOARD A TRAIN A.1 - Introduction This section deals with the installation requirements for the use of a georadar (GPR) system on-board a train. The system consists of: • a notebook computer • a battery • a GPR control unit • a GPR multiplexer unit • up to 4 GPR antennas • an odometer • and relevant connection cables. Items 1-4 will be mounted inside the locomotive and don’t need any specific installation; on the contrary, items 5 and 6 shall be mounted in the front of the train and require some mechanical arrangements. For practical reasons (mainly logistical), some of the devices needed to assure the proper mounting of the system should be provided by SNCF; basically, these consist of a metallic frame used to house the antennas and the brackets for fixing this frame to the front of the locomotive. A.2 - Mechanical requirements Mechanical installation of the antennas and the odometer requires brackets to be fixed to the buffers of the train. Therefore, it is important that the train used for the test has buffers. Moreover, it is also important that there are no obstacles between the buffers as measurements would be affected by them (see Fig. A. 1).

IDS Ingegneria Dei Sistemi S.p.A. Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 68 / 76 APPENDIX C - USING GPS WITH THE SRS SYSTEM The SRS system can acquire GPS data in NMEA$GGA format. You therefore have to set the GPS receiver so that the data output through the serial port or Ethernet port is in NM EA$GGA format. The serial or ethernet communication between the GPS and the Panasonic CF-30 notebook computer must be set up for GPS as follows: • Baud rate: 9800; • Byte size: 8; • Parity: No; • Stop bits: 1. GPS data acquisition procedure with the SRS_PLUS system: Step 1 Connect the GPS receiver to the Panasonic notebook computer using the serial cable shown in pictures Fig. C. 1. Fig. C. 1 - Connecting the GPS to the notebook computer Step 2 Open the External device settings after having clicked on the SRS software icon at the top left of the main window (see pictures Fig. C. 2 and Fig. C. 3). Fig. C. 2 - External device settings command
IDS Ingegneria Dei Sistemi S.p.A.

IDS Ingegneria Dei Sistemi S.p.A. Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 70 / 76 Fig. C. 5 - Com settings window For example, selecting External device type RS-232 GPS :  Select 1 in the Com menu (or set the number of the COM port number the GPS is connected to) and the other parameters according to the GPS characteristics;  Use the Refresh rate field in Fig. C. 3 to select the number of sweeps interval the GPS data will be acquired with; for example, if you have set the Acquisition Step to 2.4cm and the Refresh rate field to 20, the system will acquire GPS data every 48cm (2.4cm *20=48cm); if the Refresh rate = 1, the SRS_PLUS system will uptake all the information produced by the GPS according to the time parameters set on GPS equipment. Step 5 Accept the parameters set in the COM settings field by clicking the OK button, as shown Fig. C. 5. Step 6 Correct functioning of the GPS and its communication with the SRS_PLU S system is indicated by the GPS spy light in the acquisition window; when the light is green, the GPS is correctly connected and functioning; when the GPS is red, either the connection between the GPS and SRS_PLUS systems has not been correctly made or the GPS is switched off (see picture Fig. C. 6). Fig. C. 6 - GPS spy GPS spy light
IDS Ingegneria Dei Sistemi S.p.A. Protocol: MN/2009/030 - Rev. 1.2 Safe Rail System Data Acquisition Software 71 / 76 ! WARNING Remember that the GPS spy light only indicates the correct functioning of the GPS, not the accuracy of the GPS readings; to evaluate precision, use the tools supplied with the GPS system Step 6 The GPS data in NMEA$GGA format are saved as an ASCII file in the same directory as the radar data; the GPS files have the same numbering as the radar files, but have a *.GPS extension (see the example shown in the picture Fig. C. 7). During the radar data acquisition phase, you can check the GPS acquisition data using white M arkers placed at the bottom of the radar map.
