AVC Prevention Systems

The AVC prevention tools that will be installed have the following functioning and structure (Figure 1): A set of Passive infrared (PIR) sensors and/or a thermic camera (1) registers the presence of an approaching animal and sends the information to the electronic control unit (2). This unit triggers an alert signal for drivers (3), inviting them to slow down to an acceptable speed. A radar doppler sensor (4) measures whether the car actually slows down. If it does, the system stops to act. Otherwise, the radar sends a signal back to the control unit. This activates an acoustic scaring device (5), which shall drive the animal to escape. 

The functioning of the system is controlled through a modem, which sends an email each time a component is triggered (wildlife presence sensors and acoustic scaring device), and also sends information about the charge level of the batteries. Moreover, remote information can be received about the functioning of the flashing lights, and on whether the passing vehicles slow down or not. 

A specific software has been developed in order to collect all this type of information, as well as an App through which is possible to control and change the setting of the different components of the systems.

The added value of this system is that it intervenes only in risk situations, when there is the simultaneous presence of an animal on the road side and the approach of a car that p
