Obstacle Detection System for Level Crossings
Sirio-LX is an automatic radar-based system for railway safety, designed to prevent trains from colliding with obstacles on the track at level crossings. It uses short range high resolution radar to detect objects that enter the area before or while the gates are closing and provides a warning to approaching trains via the existing signaling system.
Operational in any weather condition, including fog, rain and snow, Sirio-LX provides good discrimination between different types of object. These include vehicles, motorbikes and bicycles as well as pedestrians, and detection is possible whether stationary or moving.
Sirio-LX has a very high mean time to failure (MTBF) and has been designed to ensure the highest level of safety standard (SIL4, CENELEC 50129) therefore providing a high level of safety and protection for users of level crossings as well as rail passengers.
STARS Railway Systems is a consortium that has been formed by IDS and Intecs that was founded to develop and manufacture radar based safety systems for railways. Currently, this includes Sirio-LX which is an automatic system to prevent trains from colliding with obstacles on the track at level crossings and Sirio-OD for the automatic detection of objects which have fallen on to railway tracks in high-risk zones such as near overpasses, tunnels and areas prone to landslides.
