RailEye® Front Collision Warning
RailEye® Front Collision Warning
The RailEye® Front Collision Warning Assistant (FCWA) from EYYES recognises critical traffic situations with collision potential and actively warns the driver by means of visual and acoustic signals. The system is suitable for all rail vehicles and reliably warns of hazards. Thanks to artificial intelligence and the use of high-resolution camera sensors, the system only warns the driver if a dangerous situation actually exists. The system not only relies on detected objects in the front area of the vehicle, but also takes into account the current and pre-calculated direction of movement of the detected objects for a meaningful result.
Functional description
If an object approaches the danger zone, this information is forwarded in real time via the data interface (Ethernet) to the central control unit (train computer) via an object list when a threshold value is reached that is derived from the calculated time until an imminent collision (Time to Collision).
Depending on the threshold values, this data can then be used to generate warning signals or, if the train driver is not paying attention, for automatic brake intervention.
Visibility
With a sensor mounting height of 2.7 m and a mounting angle of 14°, the following detection characteristics result:
1.) Detected classes via DNN of the front collision warning system.
- Passengers
- Bicycles/Motorcycles
- PASSENGER CARS
- LORRY
- Train
2) Detected objects via the track detection of the front collision warning system
- Track closures
- Buffer blocks
3) Detection range for straight track
- 50m* per class at ambient conditions according to VDV191
- up to 80m* at favorable ambient conditions
* The actual minimum and maximum detection range depends on the possible positioning of the camera as well as the characteristics of the vehicle front and will be defined within the project.
Smart Components
-
Forward Facing Camera
Robust forward facing camera with excellent image quality
-
Advanced Driving Control Unit
Central control unit with integrated artificial intelligence for object recognition
-
Signaller
An optical and acoustic signal transmitter shows the status and reports actual dangers.
Digital solution for the railway
- With high-resolution camera sensors in combination with artificial intelligence
- No need to use additional sensors such as radar or LiDAR
- Actively informs the driver in critical situations by means of a 2-stage warning strategy
- Calculation of the probable direction of movement of recognised objects
- Only warns if there is an actual risk of collision by using several decision layers (desicion layers)
- Detects people, cars, lorries, buses, trams, cyclists, obstacles on the track, e.g. buffer stops
- Integrated self-diagnosis function and clear display of the system status
- Increased safety and cost savings by avoiding accidents
Recognises the course of the track and thus the vehicle’s own direction of movement as the basis for defining the danger zone (area of interest) - Can be extended with Moving Off Assistant for checking the vehicle’s proximity when leaving the station area.
- No need to break through the outer skin of the vehicle
- Only one central computer unit, even for bidirectional vehicles!
- Calibration, configuration and system updates, conveniently via web interface
RailEye® Moving-Off Assistant
The RailEye® Moving-Off Assistant monitors the near area of the front of the rail vehicle. The algorithm has been specially adapted to situations when entering and leaving stops and is a logical extension of the Front Collision Assistant for monitoring the area directly at the front of the vehicle.
