SYSTEM AND AUTONOMOUS DEVICE FOR ROAD SIGNAGE AND DETECTION

The invention relates to a system and an autonomous device for road signage and detection, designed to form a visual warning barrier, particularly applicable in the field of road safety. The system comprises a plurality of autonomous devices (2) arranged on a road (3), each autonomous device (2) comprising a control unit (11); a detection unit (10) with a proximity sensor (5) for detecting pedestrians (8) in a detection area (4); a light signalling unit (6) oriented towards the vehicles (7) approaching on the road (3); a wireless communication module (12); and an energy storage and supply unit. The control unit (11) is designed to activate the light signalling unit (6) when the autonomous device (2) detects a pedestrian (8), and to wirelessly communicate said detection to the rest of the autonomous devices (2); and to then activate the light signalling unit (6) when another autonomous device (2) detects a pedestrian (8).
