Definitions

the present invention relates to an anti-collision system for switching to level.
railway accidents can also be caused by a abnormal behavior of road users, resulting in non-compliance with the road regulations.
An example of faulty behavior is the passing of the anti-incursion barriers fitted to level crossings.
Breakdowns of barriers due to voluntary behavior or accident of a road user can also cause collisions on level crossings.
the object of the invention is to provide an anti-collision system for passage to level capable of providing an alternative to removing passages to levels while being efficient and inexpensive.
an anti-collision system for level crossing comprising road equipment located in the vicinity of the roadway at the crossing level to indicate the approach of a rail convoy and cause vehicles to stop traveling on the roadway, characterized in that it comprises detection means Obstacles on the railway crossing, arranged in the vicinity of the latter and connected to means for controlling the stopping of railway convoys traveling in upstream of the level crossing, in the presence of an obstacle on it.
FIG. 1 a level crossing of the signaling type has been represented.
automatic light (SAL) with an anti-collision system according to the invention.
the reference numeral 10 designates the railway track of a network railway and the reference numeral 12 designates a roadway of a road network.
the level crossing has road equipment intended to indicate to road users the approach of a convoy railway and stop vehicles traveling on the road, and equipment railroads intended to cause the stopping of convoys circulating upstream of the passage to level, in the presence of an obstacle.
road equipment has two half-barriers automatic anti-incursion machines, respectively 14 and 16 arranged on either side of the Railroad Crossing.
barriers 14 and 16 are controlled on opening and closing by convoy detection means (not shown in this figure) arranged on the track railway upstream of the level crossing, considering the direction of movement of the convoys railway.
detection means are conventional type means and suitable for the intended use. They will therefore not be described in detail below. We will note however they are not, for example, constituted by a detection device of the "pedal" type "conventionally fitted to rail networks.
Traffic signs, 22 and 24 respectively, piloted by convoy detection means are arranged on either side of the level crossing so as to indicate to road users the imminent closure of barriers 14 and 16 and the upcoming arrival of a rail convoy.
the traffic signs 22 and 24 are constituted by light emitting diode or liquid crystal panels for displaying variable information sequences to warn road users of the state of the passage to level, i.e. the imminent closing of the barriers, their closing in progress, ...
the level crossing is provided with optical flashing devices, of the "flash” or flashing type, making it possible to dramatically materialize the closure of barriers.
road equipment also includes a set obstacles, such as 25, separating the tracks from the roadway 12 so as to prevent crossing the level crossing chicane.
these obstacles are constituted by bollards or islands implanted in the center line of the road.
road equipment can be supplemented by devices located upstream and downstream of the level crossing to regulate traffic in shifting the queues of waiting motor vehicles upstream of the crossing, by example of retractable additional barriers.
the railway equipment making it possible stopping train convoys traveling upstream of the level crossing, in the presence of a obstacle on the latter include obstacle detection means associated with means for controlling the stopping of railway convoys.
the obstacle detection means comprise a set of cameras shots 26, 28, 30 and 32, arranged in the vicinity of the railway track of the level crossing and directed towards the latter. They are connected to a central processing unit 34, constituted by a computer in which an image processing algorithm is stored and recognition of the type of obstacle present on the track.
control means for the stop of the railway convoy comprise, connected to the central processing unit 34 and receiving at the input an obstacle detection signal delivered by the latter, a device 36 for speed control of railway convoys.
Such a device also known under the name "KVB device” includes a unit 38 for developing speed instructions intended to be imposed on railway convoys, consisting of a digital coding device connected to a set of beacons, such as 40, arranged along the track 10 upstream of the Railroad Crossing.
tags 40 also known under the name “KVB tags” are each intended to enter into communication with a speed management device (not shown), of conventional type, on board railway convoys traveling on the track rail and adapted to control the speed of the latter on the value of the speed setpoints which is transmitted to them by the tags 40.
control device 36 comprises, in input, a control relay 42 connected to the processing unit 34 and to which the obstacle detection signal, this relay controlling the commissioning of the coding device 38 for the preparation of speed instructions to be imposed on railway convoys.
anti-collision system is equipped with devices railway signaling optics (not shown) located along the railway track upstream of the level crossing and controlled by relay 42 so as to intimate an order of braking the driver of the train.
the device 36 is completed by a conventional power supply unit 44 ensuring the supply of the coding device 38 and of the central processing unit 34 as well that the supply of lighting devices equipping the level crossing so as to allow obstacle detection in low light conditions.
the central processing unit 34 receives, in addition to the images, delivered by the shooting devices, signals delivered by the equipment of the level crossing, such as signals indicating the state of the barriers, detection signals of a railway convoy, signals indicating the state of track circuits, in order to provide a indication of the position of the railway convoy, ..., so as to adapt the value of speed setpoints according to these parameters, as will be described later.
signals delivered by the equipment of the level crossing such as signals indicating the state of the barriers, detection signals of a railway convoy, signals indicating the state of track circuits, in order to provide a indication of the position of the railway convoy, ..., so as to adapt the value of speed setpoints according to these parameters, as will be described later.
control device 36 can be provided with a transmitter of radio waves controlled by the actuator 42 so as to transmit alarm signals to a corresponding receiver on board railway convoys traveling on the track railroad.
a modulator-demodulator (not shown) is connected to the central processing unit 34 for the transmission of all the information relating to the operation of the system towards a monitoring center, using a telephone network.
the central processing unit 34 is provided with storage means, "black box” type, allowing the periodic storage of the images delivered by the cameras 26,28,30 and 32.
the cameras for taking pictures are arranged in pairs on either side of the carriageway 12.
the processing unit 34 is also capable, by stereoscopic processing, to discriminate between a detected flat object, such as a shadow, a reflection, ... and a three-dimensional object (motor vehicle, pedestrian, ).
Such stereoscopic processing is carried out by comparing the images obtained by the cameras of each pair, the images coinciding for flat objects and being in offset for three-dimensional objects. Such processing is also carried out in comparing the dimensions of the non-visible areas of the roadway due to the presence of a obstacle, which differs from one camera to another for three-dimensional objects.
the detection of obstacles located on the level crossing is done by processing the images delivered by the cameras 26,28,30and 32.
obstacles likely to be present on lane 10 on approach of a train can be of different natures, we will consider, in the following the description, that these obstacles are constituted either by motor vehicles stationary on track 10, for example due to a breakdown, either by vehicles motor vehicles crossing railway line 10 while barriers 14 and 16 are closing, or when the latter are closed, despite the use of obstacles 25 intended to prevent the crossing at the level crossing.
the behavior to be obtained from a convoy on approach is adapted according to the distance at which the convoy of the type is located obstacle detected and possibly the position of the anti-incursion barriers 14 and 16.
each camera delivers to the central processing unit 34 a set of images in the form of pixels each associated with a value digital luminance, that is, for monochrome cameras, values each corresponding to a gray level.
An image processing algorithm stored in the processing unit 34, performs a filtering of the pixels delivered by the cameras, by comparing the values of luminance with one or more threshold values for detecting the contour of an obstacle.
the rest of the treatment uses a classic technique of recognition of shapes capable of determining the type of obstacle present on the crossing, by example by extracting characteristic parameters from detected objects and comparing of these parameters with predetermined parameters obtained by prior learning and each corresponding to a type of obstacle.
the central processing unit 34 actuates the relay 42 so as to transmit a stop command signal to the rail convoy then to cause emergency braking or to ensure that the mechanic performs the braking necessary to stop the rail convoy.
relay 42 operates optical railway signaling devices installed along the railway track to warn the mechanic of the risk of collision.
Speed setpoint signals and stop orders sent to beacons KVBs are developed based on the distance between the train and the type of obstacle detected, i.e. vehicle stopped before barriers are closed or vehicle trying to cross the level crossing during the closure of the latter or after closing and, possibly, of the position of the barriers.
the positioning of the pedal electronic 46 for train convoy detection and closing control barriers 14 and 16 corresponds to the distance traveled by a rail convoy during the barrier closing time. This distance is generally called “distance ad ".
Announcement distance is linked to the maximum speed of convoy traffic but is independent of the stopping distance of the latter.
a railway convoy 47 runs alongside a first group of KVB 48 beacons located at the stopping distance, that is to say a distance from the level crossing corresponding to the distance necessary for that the convoy 47 stops along the deceleration curve C1 shown in this figure.
the anti-collision system When a motor vehicle 50 immobilized on the level crossing is detected while the convoy is at such a distance, the anti-collision system generates speed instructions so as to control the deceleration of convoy 47 according to the curve C1, so as to avoid any collision.
the convoy 47 is located at the announcement distance and travels opposite the electronic pedal 46 allowing the detection of the convoy and controlling the closing of barriers 14 and 16.
the detection of a stationary or incursion vehicle in the level crossing causes an emergency braking signal to be triggered by the KVB transmission control device, at a second group of KVB 52 beacons, with a zero speed setpoint (curve C2), so that slow down convoy 47 as much as possible to limit the consequences of a collision in the if the vehicle does not have the possibility of freeing itself.
the detection of a stationary or incursion vehicle causes the emergency braking of the convoy 47.
the detection of any obstacle while the barriers 14 and 16 are in a closed position causes the emission, by a third group of beacons 54, of a setpoint signal C3 identical to the signal of C2 instruction mentioned previously so as to limit as much as possible consequences of a collision.
the anti-collision system ensures, in addition to detection of immobilized vehicles, detection of moving vehicles, i.e. foray.
the detection of a stationary or incursion vehicle causes the emission, by groups of tags 62 and 64 of setpoint signals C5 of emergency braking.
