Abstract

Il dispositivo permette di rilevare, in presenza di nebbie, un ostacolo fisso in autostrada, (incidente con occupazione delle corsie di marcia), o in movimento rallentato la cui velocità sia inferiore alla minima progettuale dell'autostrada, (es.50 Km/h). In entrambi i casi di stop o rallentamento di un veicolo, un sistema di luci intermittenti laterale alle carreggiate entra in funzione automaticamente per un tratto di 500-600 mt dal punto critico a ritroso, per avvisare i mezzi in arrivo dell'ostacolo o del rallentamento ed evitare, quindi, tamponamenti. Il sistema è formato da una serie di circuiti lineari L-C posizionati trasversalmente al senso di marcia dei veicoli sotto la pavimentazione stradale, di interasse 3,5 mt, in oscil-lazione risonante ad alta frequenza che invia impulsi ad un sistema rivelatore di ampiezza e codifica dei segnali in ON/OFF, pilotanti porte-logiche collegate ad un elaboratore dati. L'anomalia di fermo di un veicolo od il suo rallentamento indotto sui circuiti L-C all'interno di prestabiliti parametri temporali, consente all'elaboratore di accendere le luci di pericolo per i 500-600 mt. menzionati.The device allows to detect, in the presence of mists, a fixed obstacle on the highway, (accident with occupation of the driving lanes), or in slow motion whose speed is lower than the minimum design of the highway, (e.g. 50 Km / h ). In both cases of stopping or slowing down of a vehicle, a system of intermittent lights lateral to the carriageways starts automatically for a stretch of 500-600 meters from the critical point backwards, to warn the incoming vehicles of the obstacle or of the slowdown and therefore avoid rear-end collisions. The system is made up of a series of LC linear circuits positioned transversely to the direction of travel of the vehicles under the road pavement, with a spacing of 3.5 meters, in high frequency resonant oscillation which sends impulses to a detector system of amplitude and coding ON / OFF signals, driving logic gates connected to a data processor. The failure of a vehicle to stop or its slowdown induced on the L-C circuits within preset time parameters, allows the computer to turn on the hazard lights for 500-600 meters. mentioned.
