Abstract

Device for detection of falling objects that distinguishes between the rocks retained or allowed to pass according to their size and impact energy, particularly applicable for protection of land travel routes, communications routes or other infrastructures, in certain areas of these that may be affected by falling objects that can obstruct or damage them. It consists of a barrier (1) made up of mesh (2) attached to some posts (3) equipped with a number of connectors (30) that have outlets connected to an electrical cable (31), which has a closed circuit connection to a battery centre (35) and a transmitter and antenna or optic fibre cable power supply control centre (36). The connectors (31) are used for insertion of plugs (6) that, as a result of the limits (12) especially designed for this purpose, secure the mesh (2) while also closing the mentioned electrical circuit. The battery centre (35) generates the power required to maintain the system active, the transmitter and antenna or optic fibre cable power supply control centre (36) being connected to the system in such a way that, when the current cannot complete the circuit because one of the connectors (30) has been released, because there has been a failure in the battery centre (35), or any other reason, it sends an alarm signal to a control centre it is connected to.
