Definitions

  • the present invention concerns the technical field relative to the safety in the field of transport on railways, such as trains and underground systems.
  • the invention refers to an innovative safety device able to detect beforehand the presence of an obstacle on the tracks so as to give the engine driver time to execute a braking manoeuvre in complete safety.
  • the level crossing can in fact be ignored by pedestrians, which cross by passing below the bar, therefore risking their lives. There have been several fatal accidents due to this.
  • crossing points which are provided only with traffic light signalling and not with a level crossing are not at all uncommon, and they clearly render the crossing even more risky.
  • one or a plurality of sentinel apparatus (3) are provided, placed along the route of the train (1) in correspondence of the crossing points (2) that want to be monitored.
  • Each sentinel apparatus (3) is provided with an image acquisition device (5) and transmission means (6) for transmitting the images acquired.
  • image acquisition device (5) and transmission means (6) for transmitting the images acquired.
  • transmission means (6) for transmitting the images acquired.
  • a receiving device (10) when in use installed on the train, which displays them on a screen.
  • the engine driver has the possibility of seeing.live the shots relative to the crossing point that he is approaching, being able to possibly brake in advance in case an obstacle is present on the line.
  • activation means 11, 12, 13, 14
  • de-activation means 11, 12, 13, 14
  • the receiving device comprises:
  • the minimum activation distance can be set, in the route direction of the train, in about 1.500 metres from the sentinel apparatus, while the de-activation distance can be set in about 100 metres from the overcoming of the sentinel apparatus.
  • the sentinel apparatus (3) further comprises:
  • the power supply means (8) can comprise one or more photovoltaic panels.
  • a remote control unit can be further provided, in communication with one or more sentinel apparatus so as to monitor the placement areas of these sentinel apparatus.
  • the remote control unit comprises a video communication with all the sentinel apparatus (3) so as to display on a screen of the control unit the shots (5) of these sentinel apparatus and a vocal communication with the sentinel apparatus through the loudspeakers/microphones (7) arranged on the sentinel apparatus so that the operator can, from the operations centre, hear and communicate directly with the monitored area.
  • the sentinel apparatus can comprise a turret (4) on which the image acquisition device (5) and the transmission means (6) are arranged.
  • the image acquisition means (5) comprise one or more than one cameras (5).
  • the receiving device (10) can comprise in an integrated manner the activation and de-activation means.
  • the receiving channel (12) comprises a plurality of channels each channel with one frequency such that each frequency result associated to one sentinel apparatus (3) so that the processor can selectively choose the corresponding channel for the reception of the images.
  • railway line comprising a train (1) and the route made by the said train and characterized in that the railway line further comprises:
  • the operation of acquisition of the images comprises a shot through one or more than one cameras (5) that film in continuous operation or in correspondence of the passing of the train.
  • the acquisition of the images exclusively in correspondence of the passing of the train is controlled through the acquisition of a closure signal of the level crossing and sending of the said signal to the camera (5), which is activated.
  • the memorization of the data sent by the satellite (15) is comprised, the said data being GPS geographic coordinates, date, time and speed of the train.
  • Figure 1 shows a train 1 in transit through a crossing area 2 (pedestrian and/or vehicular) represented by a level crossing.
  • Always figure 1 shows a sentinel apparatus 3 arranged in proximity of the crossing area so as to be able to perform its function, which will be described below.
  • the sentinel apparatus 3 comprises a turret 4 that serves as a support for some components.
  • image acquisition devices 5 are comprised, such as for example one or more than one camera 5, which are installed on the turret so as to be able to aim and acquire images relative to the crossing area 2.
  • One or more than one directional antenna 6, preferably two, are arranged on the turret, generally on the top of it in an appropriate position to perform their function.
  • the turret 4 also serves as a support to a loudspeaker/microphone device 7.
  • the power supply of the systems described above can be provided through solar panels 8 or, alternatively, through the railway electric network.
  • Always figure 1 shows further accessories, such as backstairs to access to a step-on platform (for example, for the maintenance of the cameras) and a cupboard 9 for containing the supply and control systems of the components described above.
  • Such turrets 4 are therefore installed on the railway network along the various railway lines in correspondence of all the areas that want to be monitored, naturally independently of the fact that such areas are provided with a level crossing or not.
  • Figure 2 schematically shows a second element which is part of the present safety device and comprising a receiving device 10, destined to be installed on the train, and configured so as to be able to receive the images sent by a sentinel apparatus 3 and to see them on a screen.
  • the receiving device comprises a monitor 10 provided with a screen.
  • the receiving device operates in a 2,4 Ghz band.
  • the range of action is substantially defined through an activation point and a de-activation point for each sentinel apparatus 3.
  • the activation point represents, along the motion direction of the train, the minimum distance of the train from the specific turret 4, which, once reached, the reception on the monitor of the images sent by this specific turret is enabled, hindering the reception of other signals.
  • the de-activation point always along the motion direction of the train, represents the overcoming distance of the turret, beyond which the monitor de-activates the reception of the images sent from the said turret, that is it interrupts the communication.
  • Figure 3 schematically shows a train travelling along a direction and highlights the above mentioned activation point that, once reached, the monitor 10 configures itself to acquire the signals, in particular the images, sent from the turret 4 through the two antennas 6. In such a manner, the images are displayed on the screen of the monitor 10.
  • the monitor has been represented outside the train's operating cab.
  • the monitor 10 de-activates the reception and remains on stand-by to be configured to admit the reception of signal of a subsequent turret that it finds along the route.
  • the activation distance can be set in about 1.500 metres and the de-activation distance in about 100 metres.
  • different ranges can be pre-chosen without for this moving apart from the present inventive concept.
  • the activation distance can be increased so as to allow a greater brake margin.
  • the monitor In order to select the correct reception of images, the monitor is provided with a plurality of reception channels, each one in a specific frequency so that each channel is enabled to receive the signal emitted by only one specific turret 4. In such a manner, once a channel has been selected, the monitor receives the signal of the said turret, hindering the other information relative to all the other emitting turrets.
  • the GPS receiver 11 receives, according to a certain time sequence, the information of the position of the train from a satellite 15.
  • the monitor (or separately from the monitor) comprises a memory 13 and a micro-controller 14, for example a processor, which work in combination with the satellite signal 15 received.
  • the monitor 10 therefore receives the signal from the satellite 15 through the GPS receiver 11 so as to identify continuously the current position of the train and of the monitor installed on it.
  • the processor 14, through an appropriate software and algorithm, compares continuously the current coordinates received from the satellite 15 with the ones memorized on the memory 13.
  • the processor From such a comparison, as soon as it identifies a substantial equivalence between a coordinate received from the satellite and a coordinate contained in the memory, the processor elaborates such a coordinate and elaborates the information. The processor will find the frequency associated to such a coordinate and will be therefore able to activate the corresponding channel of the monitor for the reception of the images.
  • the de-activation takes place in exactly the same way, once the train has reached the de-activation point and the processor has recognized such a condition.
  • Figure 5 highlights the sending of the signal from the satellite 15 and the acquisition of the images when the monitor is synchronized on the correct channel once the activation point has been reached.
  • Figure 4 shows the de-activation of the reception, that is the switching off of the reception channel of the monitor, once the processor has verified that the current position coincides with a position memorized in memory to which the de-activation corresponds.
  • the flow chart of figure 6 schematically shows the system of functioning described.
  • the flow chart 6 shows the calculation "loop" in which the processor compares the current position with the ones memorized so as to recognize when the train approaches a sentinel apparatus 3 to activate its reception channel and switch off the reception one the de-activation point has been reached.
  • the coordinates in memory could possibly be organized in two groups, that is the group of activation points and the group of de-activation points.
  • a remote control operations centre can be further involved, so that an operator can monitor continuously, or during the transit of trains, one or more than one critical crossing points.
  • the operator can communicate with any sentinel apparatus 3. For example, through twisted pair telephone, he can talk and hear with a pre-chosen sentinel apparatus through the loudspeaker and the microphone 7, respectively.
  • the acquisition of the images by the cameras can take place in a continuous cycle or only in correspondence of the approaching of a train.
  • the acquisition of images and transmission of them can be foreseen in correspondence of the passing the train, acquiring, for example, the closure signal of the bars and using this for the beginning of the shot.
  • the train is in transit along a track of a railway network and approaches a monitored area 2, for example the level crossing described.
  • the satellite 15, during the passing of the train sends the position signals in a continuous way and these signals are acquired by the monitor 10 and compared with the ones memorized 13 through the processor 14.
  • the processor 14 selects and activates a reception channel enabled to the reception of the images of the said specific turret 4.
  • Figure 1 therefore represents a hypothesis in which the monitor, among all the turrets arranged on the railway network, receives the signal of the turret represented in figure and that the train is approaching. Once the pre-established activation distance has been reached, for example 1.500 metres, the channel is activated and acquires the images sent by the cameras.
  • the operations centre can intervene through the loudspeaker and the microphone 7, for example by instructing the person blocked in the crossing point and calming him.
  • the channel is de-activated closing the image to prepare itself for a new reception as soon as the train enters into the range of action defined by the activation point of a subsequent turret along the route.
