Road barrier structure with an integrated system for energy generation and detection and classification of collisions

摘要

A road-barrier structure is provided with a plurality of piezoelectric modules (3) integrated in a wall (2) thereof and distributed along the latter. The wall (2) is shaped and set in such a way as to be subject to vibrations as a result of the passage of motor vehicles along the road on which the road barrier is installed. The piezoelectric modules (3) are arranged and oriented for exploiting said vibrations in an optimal way in order to produce electrical energy. Furthermore, the piezoelectric modules (3) are arranged in such a way as to be able also to perform, together with the function of generators, also the function of deformation sensors, designed to detect collisions against the road barrier. The modules (3) are connected to an electronic control unit (4) programmed for processing the signals at output from the piezoelectric modules (3) and classifying the detected collisions against the road barrier on the basis of a predetermined scale of seriousness. The control unit (4) is supplied with the energy generated by the piezoelectric modules (3). The electronic control unit (4) moreover includes wireless transmission means (9) for transmitting the information regarding the data detected.
