Abstract (en)
An obstacle detection device comprising at least one microwave beam detector (2), associated with an LED light emitter (4) whose turning on depends on the type, frequency and duration of the obstacle interception (A). After a preset period of time, the detection is radio activated to a series of other equal devices, preceding (and/or following). A Control Centre is alerted that the LED panels (4), from the position of the activated devices to the positions of sequential devices, are turned on and are signalling to the vehicles passing by that their are approaching an obstacle, such as a road accident, a slowing down, road-works, fog or the like.
