Definitions

  • This invention is related to a level crossing system that is sensitive to speed and has image recording and transmission properties for utilization at level crossings.
  • level crossings are used at junction points of railways and highways. These level crossings consist of elevated sections between the railways, at the same height as the surfaces of the highway and the railway, in a manner that would make the passage of the pedestrians and highway vehicles possible.
  • barriers that are placed in parallel to the rails preventing the entry of highway vehicles in the crossing for purposes of preventing any collision of railway and highway vehicles.
  • these barriers are of the type that can be opened and closed and to serve this purpose sensors are placed on the railway at a distance of 1000 to 1500 meters away from the crossing.
  • a warning in the form of light and/ or sound is transmitted to the barrier and the barrier is closed upon receiving this warning.
  • the barrier is lifted off to open the level crossing to the highway traffic again.
  • the vehicles are required to wait 2 or 3 minutes until the train clears through the crossing.
  • the high speed trains can go the subject matter distance of 1000 to 1500 meters fast while slower ones take longer. Due to the long waiting periods some drivers attempt to cross the passage by going in between the barriers and this leads to dangerous and even fatal consequences.
  • the operator of the train can have the view of the crossing at a distance of a couple of hundred meters from it, however if flat surfaces do not stretch far such a distance is not sufficient for the train to stop and prevent a collision.
  • EP 0976640 numbered European patent document a system that prevents collisions at level railway crossings is mentioned.
  • the subject matter system includes a video camera that records and processes the images in three dimensional format from the level crossing.
  • This system at the same time identifies the type of the barrier at the crossing and contains a control system that sends, if necessary, speed control warning or brake command to the train that is approaching the crossing.
  • the purpose of this invention is to create a level crossing system in which the images from the crossing are recorded.
  • Another purpose of this invention is to create a level crossing system through which the images from the railway are transmitted to the railway vehicles through wireless transmission.
  • Another purpose of this invention is to create a level crossing system that would shorten the waiting period of the highway vehicles at the level crossing during the passage of the railway vehicle from the crossing.
  • Another purpose of this invention is to create a level crossing system that is sensitive to the speed of the vehicle on the railway.
  • the level crossing system that is the subject matter of the invention (1) contains:
  • Barrier (2) consists of a body (21) that is fixed to the ground and an arm (22) that is connected to the body on one side.
  • the arm (22) can rotate on a plane that is at a vertical angle to the highway, on the side that it is connected to the body (21).
  • the arm (22) becomes horizontal it settles at a level that would not be possible for the highway vehicles (K) to pass under and as such the entry of the highway vehicles in the level crossing is prevented.
  • the arm (22) takes up a position that is vertical above the body (21) and opens up the crossing to the Highway Vehicles (K).
  • the warning device (3) is activated by the control system (5) with the basis of the status of the Train relative to the level crossing and ensures that the highway vehicles (K) are informed of the whereabouts of the train (T) by audio and/ or visual means.
  • Imaging system (4) contains at least one camera (41) that instantaneously records the image of the level crossing, and
  • two imaging systems (4) are used.
  • the cameras (41) have night vision capability and as such they ensure that that the imaging system (4) is active on a 24 hour basis.
  • At least two cameras (41) are used. At least one camera (41) is placed facing the highway and at least one from the remaining is placed facing the crossing. This ensures that the image records can be accessed as needed and such records may be used as evidence in any accidents that may take place.
  • the recording device (42) is a digital video recorder that records the images received from the cameras (41) on its hard disc (Digital Video Recorder - DVR).
  • At least one transmitter (43) is used in each imaging system (4).
  • directional antennas that preferably operate at 2.4 GHz or higher frequency, with more than 18 dB of recovery are used as the transmitter. As such, it would be possible to broadcast to the necessary range even under adverse weather conditions.
  • the communication between the Transmitter (43) and receiver (44) is achieved via signals sent by the transmitter (43) to the receiver (44).
  • the receiver (44) can perceive the signals at a certain distance from the transmitter (43). This distance is far enough to make possible for the train (T) to slow down sufficiently and even stop before it reaches the crossing, in case of a dangerous situation.
  • the subject matter distance is preferably between 1500 to 5000 meters.
  • the screen (45) is located in the locomotive. When there is no level crossing close to the Train (T) the screen (45) reflects crossing image.
  • more than one camera (41) is used and for this reason the image (45) on the screen is divided into the number of cameras (41) used and the images from all the cameras (41) are displayed at the same time.
  • the control system (5) included in the level crossing which is the subject matter of the invention, contains at least one sensor (51) that is placed on the rail to determine whether the train (T) is approaching the level crossing, and at least one control unit (52) that ensures control of the barrier (2) and warning device (3) by arranging the warning signals sent by the sensor (51).
  • the sensor (51) from its position on the rail senses the approach of the train (T)
  • the control unit (52) evaluates the signal it receives and ensures that the barrier (2) is closed within a pre-determined period of time on the basis of where the sensor (51) is placed and the specifications of the train (T) arriving (load train, fast speed train, etc.), and moreover, it is ensured that the warning device warns the vehicles passing through the highway (T).
  • the control system (5) contains four sensors for each direction (A1, B1, C1, and D1) as well as a control unit (52).
  • a control unit (52) In other words, on double lane railways (arrival and departure lanes) eight sensors are used (A1, B1, C1, D1, A2, B2, C2, and D2).
  • three of the sensors On both lanes, three of the sensors (A1, A2, B1, B2, C1, and C2) are placed in the direction that the train (T) approaches the crossing and the fourth sensors (D1, D2) are placed on the rail facing the direction that the train leaves the crossing.
  • the sensors (51), which are placed in the direction that the train approaches the crossing, must preferably be positioned on the rail at varying distances.
  • the first one of the sensors that is on the same side of the railway relative to the crossing (A1, A2) at a distance that is sufficient for the train to stop the second sensor is preferably placed 100 meters further from the first one (B1, B2) and the third sensor (C1, C2) must be placed at a distance of approximately one kilometer to the first sensor (A1, A2).
  • the fourth sensor (D1, D2) is placed on the side of the crossing that the other sensors are not present (A1, A2, B1, B2, C1, C2).
  • the control unit (52) on the basis of the signals received from the sensors (A1, B1, C1, D1, A2, B2, C2, D2), performs functions such as opening or closing the barrier (2), changing of the symbols on the warning device (3) and similar.
  • the control unit (52) When the train (T) reaches sensor one (A1, A2), the control unit (52) ensures that the warning device (3) transmits the first warning for the vehicles on the highway (K).
  • the control unit (52) calculates the speed of the train when the train (T) reaches the second sensor (B1, B2) by dividing the distance between the first and second sensors (A1, B1, A2, B2) into the time that it takes for the train to travel from the first sensor (A1, A2) to the second sensor (B1, B2).
  • the control unit (52) changes the symbol on the warning device (3).
  • the rate of slowing down of the train is calculated and then the time required for the train to reach and leave the crossing is found.
  • the arm (22) starts to turn down at approximately 45 seconds before the train (T) reaches the crossing and ensures that the barrier (2) closes the crossing to the traffic from the highway.
  • the waiting period of highway vehicles does not change on the basis of the speed at which the train (T) travels.
  • the control unit (52) ensures that the arm (22) is lifted in line with the signal received from the sensor (D1, D2) and as such the level crossing opens up to the highway vehicles (K).
  • the warning device (3) in line with the directives received from the control unit (52), warns the highway vehicles (K) by visual and/ or audio means that the train is approaching.
  • the warning device (3) is capable of sending different warnings on the basis of the number of sensors (51) used in the system.
  • the warning device is made up of numerous red colored LEDs, placed in matrix format. When there is no train approaching the level crossing, these LEDs remain off and no visual activity can be observed on the warning device (3).
  • the warning device (3) can preferably send three different types of warning based on the distance of the train (T) to the level crossing.
  • the first warning is given with the signal sent from the first sensor (A1, A2) to the control unit (52). This warning is preferably in the form of flashing LEDs.
  • the second warning is given with signal sent by the second sensor (B1, B2) to the control unit (52).
  • the second warning preferably is a "STOP" sign in the language of the country where the level crossing system (1) is located.
  • the third warning is given when the closing of the barrier (2) is started. Following the closing down of the barrier (2), the third warning is issued and this warning continues to be issued until the train (T) leaves the crossing.
  • the third warning is preferably the countdown in seconds (approximately 45 seconds) of the total time that the barrier (2) will stay closed.
  • the warning device (3) is placed on the body (21) of the barrier in a manner that would make it visible to the highway vehicles (K).
  • the warning device (3) is placed on the arm (22) of the barrier in a manner that would make it visible to the highway vehicles (K).
  • the warning device (3) is placed on the side of the highway in front of the barrier in a manner that would make it visible to the highway vehicles (K).
