Definitions

  • the present invention relates to a crash alarm system for a railway vehicle.
  • Document CN203766823 discloses a railway wagon anti-collision system comprising an infrared emitter, an infrared receiver, a laser distance measuring instrument and a long-distance LED (light emitting diode) projection lamp, the system being arranged on a wagon head of a railway wagon.
  • Document LV14384 discloses another train anti-collision device containing a movement direction detector connected with a braking program unit.
  • One object of the present invention is therefore to provide a crash alarm system for a railway vehicle which is simpler than similar systems usually applied to automotive vehicles, which is easy to install and cheap.
  • the crash alarm system for a railway vehicle is an electronic system that is able to intervene through an optic-acoustic signal in order to warn the driver about the possibility of a collision between the vehicle on which it is installed and a potentially colliding vehicle or obstacle, particularly in the event the driver has not activated the speed regulation system of the railway vehicle (accelerator and brakes).
  • Figure 1 shows a schematic lateral view of a first railway vehicle 1 moving along a railway track 2 on which a second railway vehicle 4 is also present, at a distance D.
  • the first railway vehicle 1 moves at a first speed S1 while the second railway vehicle moves at a second speed S2, in the same or in the opposite direction with respect to the direction of movement of the first railway vehicle 1. If the second railway vehicle 4 moves in an opposite direction with respect to the direction of movement of the first railway vehicle 1, the second speed S2 is negative.
  • the railway vehicle 1 is equipped with a crash alarm system 6 which comprises a sensor module 8 and an alarm module 10.
  • the sensor module 8 comprises several devices such as a laser sensor, a radar sensor and/or a video-camera arranged to calculate in a manner per se known the distance D between the first railway vehicle 1 and the second railway vehicle 4.
  • the devices present in the sensor module 8 are per se known and they are robust in terms of weather condition, in particular, they allow the sensor module 8 to calculate the distance D both when the sun is in front of the first railway vehicle 1, and when there is sunlight from a lateral side, with shadow generation on sensor module 8 itself, and at night, i.e. considering lighting system installed on the first railway vehicle 1 not enough strong to make any obstacle present on the railway track 2 visible and under the hypothesis that no other light sources are available.
  • the sensor module 8 is placed in front of the first railway 1 and is therefore arranged to analyze the portion of the railway track 2 placed between the first railway vehicle 1 itself and the second railway vehicle 4, and to transmit a distance value representative of the distance D to a control unit 12 of the first railway vehicle 1.
  • the transmission of the distance value D is preferably done in a wireless mode, for example through a wi-fi communication.
  • the sensor module 8 is removable to prevent thefts and the distance between the sensor module 8 and the control unit 12 can be up to 20m, depending from the composition of the railway vehicle 1, therefore, the wi-fi technology for communication with the control unit 12 is the preferred solution to have elasticity in the design of the overall system.
  • the control unit 12 is arranged to acquire, in a manner per se known, the first speed S1 from the first railway vehicle 1 and the second speed S2 from the second railway vehicle 4, and to elaborate these speed signals together with the distance value D as herein below disclosed, to decide whether to send to the driver of the first railway vehicle 1 an alarm using the alarm module 10.
  • control unit 12 is arranged to receive the first speed S1 from a speed sensor installed on the first railway vehicle 1 itself, and to calculate the second speed S2 of the second railway vehicle 4 through an elaboration per se known of a plurality of data acquired by the sensor module 8 and relative to the second railway vehicle 4. This plurality of data is acquired by the various devices of the sensor module 8, in a manner known per se.
  • the control unit 12 After having acquired the speeds S1 and S2, the control unit 12 is arranged to determine if the distance D starts decreasing. For example, consecutive measurements of the distance D are calculated at predetermined time intervals by the sensor module 8, and iterative comparisons are done by the control unit 12 between each new distance value and the previous ones, in order to evaluate if there is a decreasing trend of the distance values.
  • control unit 12 calculates in a manner per se known the relative speed of the first railway vehicle 1 with respect to the second railway vehicle 4, and if the first speed S1 is greater than the second speed S2, the control unit 12 send an activation signal to the alarm module 10 which in turns activates an alarm.
  • the detection capability of the decreasing of the distance is the result of the braking capacity of the first railway vehicle 1 related to its travel speed, without any difference in case of straight railway track 2 or in case of presence of curves.
  • the decrease of the distance D can happen in the following situations:
  • the alarm module 10 which is placed inside the first railway vehicle 1, activates an alarm according to the following rules, based on the value of the distance D, in particular based on the value of the last measurement of the consecutive measurements or on any value of the distance D which satisfies the following conditions:
  • the sensor module 8 in order to ensure the correct detection of dangerous situations, has to be able to identify and eliminate from the analysis any obstacle which is not actually on the railway track 2.
  • the main objects which have not to be identified as possible obstacles are poles, station sidewalks and signaling components (in particular, elements below a predetermined threshold from the iron plane, for example 40cm, must not be detected).
  • the crash alarm system of the present invention is a protection system "stand-alone" in the sense that if a railway vehicle is equipped with the system itself, it can deal with all the dangerous situations independently of equipment installed on other railway vehicles moving on the same railway track 2.
  • the crash alarm system of the present invention is suitable also for people protection, because, for example, it can advise the driver of the first railway vehicle 1 in case of presence of people on the railway track 2. In fact, a person is pretty like a convoy with second speed S2 equal to zero.
  • the system works everywhere because it doesn't need external signals such as GPS signals, Wi-Fi signals from ground emitters, devices mounted on others railway vehicles, etc., so that tunnels or old lines without particular predispositions are not a problem for the correct functioning of the crash alarm system of the present invention, and the equipped railway vehicle is able of detecting any "obstacle" present on the railway track 2, such as persons, other railway vehicles, cars, etc.
