tracking and reporting prior automatic barriers on the highway, in the presence of fog.

摘要

the device allows to detect, in the presence of fog, a fixed obstacle in highway (incident with employment of lane road)moving or slowed down the speed is less than the minimum design of the highway (es.50 km / h).in both cases, to stop or slow down of a vehiclea system of flashing lights, side the lanes in function automatically for a stretch of 500 - 600 m from the critical point backwards.to warn the vehicles arrival of the obstacle or slowing down and avoid, so, rear end collisions.the system consists of a series of linear circuits, l - c positioned transversely to the direction of travel of vehicles under the pavement, wheelbase 3.5 mt.in oscil used resonant high frequency sends pulses to a system detector of size and encoding of signals in the on / off button, pilotanti doors - logic connected to a computer data.the anomaly of the stop of a vehicle or its slowdown led circuits l - c within predetermined time parameters.allows the computer to turn on the lights of danger in the 500 - 600 m mentioned above.
