Radio system to optic confirmation for survey transmission and events recording of incorrect guide provided of longitudinal control of speed and distance and automatic device of deceleration and braked for road vehicle

摘要

System which permits to send and radio orders optical confirmation among cars provided with the same signal transmitting unit to be used for incorrect driving warnings or for sanctionatory activities.;The system, which also motorizes the engine and the brakes of the car, is essentially constituted by three units: an entry unit generating an encoded signal to be transmitted and visible on a display; a transmitting and receiving unit which has to transmit and receive the encoded radio signal; a leading unit which manages the relies working and generates an order when the reception , with anti-collision check, has occurred and can be re-send to the entry unit.;The system can generate signals randomly encoded in the same frequency, so that it would be absolutely improbable that to more cars produce and receive the same signal at same time; the signals are received and analyzed by receiving-transmitting antennas and the reproduced through a transponder placed in the back of the car having an adequate screen set so that to catch only the radio waves coming from the following car. The optical radio system can also include an independent device that surveys the security distance through the collimate ray emission and is combined with a video camera filming the incorrect driving behaviour of the following car, its number plate and even the driver's image to be automatically transmitted to the police. Differently from the other radar based system, this system proves itself to be cheap and reliable in every environmental, weather and road conditions.
