FR-A-2 721 129, DE-A-4 100
  • the object of the present invention is to provide a road-barrier structure, which as compared to the known solutions presents the advantage of being in the form of an integrated structure that is easy and fast to install and is designed to perform simultaneously a multiplicity of functions that cannot be achieved together by any of the known devices.

  • the piezoelectric modules prearranged in the structure, in association with the electronic control unit are able to perform both the function of generators, exploiting the vibrations to which the structure is subject as a result of the passage of motor vehicles along the road (produced by the vibrations of the ground and/or by the displacement of air) as well as the function of detecting and classifying the possible collisions.
  • the aforesaid electronic control unit is associated to wireless transmission means for transmitting information regarding the data detected.
  • the electronic control unit is connected to a plurality of sensors of environmental parameters, such as, for example, a temperature sensor, a humidity sensor, a light sensor, and a smog sensor, said sensors also being carried on said road-barrier structure and being supplied with the energy generated by said piezoelectric modules. Also said sensors of environmental parameters are equipped with wireless transmitting means designed to transmit information on the environmental parameters detected.

It is important, according to the invention, that the arrangement and conformation of the wall 2, as well as the arrangement and conformation of the piezoelectric modules 3, should be such as to cause said piezoelectric modules 3 to undergo a deformation as a result of vibrations to which the wall 2 is subject as a result of the passage of motor vehicles along the road on which the road barrier is mounted.

  • the aforesaid WSN operates with the energy generated by the aforesaid piezoelectric modules 3 so that the unit according to the invention is altogether autonomous .
  • the electronic control unit 4 uses the signals issued by the piezoelectric modules 3 also for classifying the deformations to which said modules are subject, according to a series of pre-set threshold values. Below a lower threshold value, the deformations are identified as due simply to the vibrations transmitted by the passage of a motor vehicle. The signals below said threshold value can then be used to make a count of the number of the motor vehicles travelling along the road. Above upper threshold values, the deformations to which the piezoelectric modules are subject are identified as due to collisions. The degree of the collision can be classified according to seriousness, where a distinction is made between minor impact, caused for example by pedestrians, and impact of greater seriousness.
  • the system can be prearranged for generating an alarm. Also in order to transmit the information on the count of the vehicles passing and on the collisions, the unit 4 is associated to a wireless transmitter 9, which is able to issue a wireless signal 10 containing the aforesaid information .
  • the structure according to the invention presents the advantage of having the piezoelectric modules 3 integrated within it, to the advantage of the ease and rapidity of installation.
  • the device according to the invention is characterized in that it is multifunctional, providing both for generation of energy, which is used both to enable the autonomous supply of the WSN and to detect and classify the types of impact, including the function of counting the motor vehicles travelling along the road.

Abstract

La présente invention concerne une structure de barrière routière équipée d'une pluralité de modules piézoélectriques (3) intégrés dans une paroi (2) et réparties le long de celle-ci. La paroi (2) est formée et configurée de manière à être soumise à des vibrations provoquées par le passage de véhicules automobiles le long de la route sur laquelle la barrière routière est installée. Les modules piézoélectriques (3) sont agencés et orientés pour utiliser lesdites vibrations d'une manière optimale afin de produire de l'énergie électrique. En outre, les modules piézoélectriques (3) sont agencés de manière à remplir, conjointement avec la fonction de générateurs également, la fonction de capteurs de déformation, destinés à détecter des collisions contre la barrière routière. Les modules (3) sont connectés à une unité de commande électronique (4) programmée pour le traitement des signaux à la sortie des modules piézoélectriques (3) et la classification des collisions contre la barrière routières détectées sur la base d'une échelle prédéterminée de gravité. L'unité de commande (4) est alimentée en énergie par les modules piézoélectriques (3). L'unité de commande électronique (4) comporte également des moyens de transmission sans fil (9) pour transmettre l'information concernant les données détectées.
