Abstract

L'invention concerne un système d'alarme radio-électrique. Ledit système comprend un émetteur 12 pour émettre continuellement une onde radio à une fréquence de résonance F1 autour de la construction à protéger pour établir un réseau radar de surveillance, un dispositif 20 de détection sans fil, exempt de source de courant, fixé à une surface solide 16 pour recevoir l'onde radio et engendrant un potentiel de résonance pour transmettre une onde radio à une fréquence amplifiée F2 lorsqu'il subit un choc, et un récepteur destiné à déclencher un dispositif d'alarme. Application à la protection de constructions telles que des immeubles résidentiels ou autres.The invention relates to a radio alarm system. Said system comprises a transmitter 12 for continuously transmitting a radio wave at a resonant frequency F1 around the building to be protected to establish a surveillance radar network, a wireless detection device 20, free of current source, fixed to a surface solid 16 to receive the radio wave and generating a resonance potential to transmit a radio wave at an amplified frequency F2 when it is subjected to a shock, and a receiver intended to trigger an alarm device. Application to the protection of constructions such as residential buildings or others.
