Abstract

L'invention concerne un système de sauvetage selon lequel une personne (55) tombée dans l'eau depuis un bateau (46) porte toujours un émetteur portable (41), par exemple suspendu au cou. L'émetteur portable (41) est équipé d'un capteur de détection d'eau. Un signal de détection d'eau est alors généré par l'émetteur, et reçu par un émetteur-récepteur (42A). Une unité (45) de commande de moteur connectée à l'émetteur-récepteur (42A) commande le bateau (46) qui retourne près de la personne (55) tombée à l'eau et arrête un moteur (47), l'arrêt de celui-ci par inertie étant également pris en compte. L'émetteur-récepteur (42A) est également équipé d'un système GPS destiné à indiquer une adresse préétablie d'une position de chute et d'une heure de chute par l'intermédiaire d'une station (202) de base, et au moment de la chute dans l'eau, un appareil de sauvetage tel qu'une bouée de sauvetage est lâché et une échelle peut être installée afin que la personne (55) tombée à l'eau puisse retourner sans aide dans le bateau. Ainsi, même si une personne tombe dans l'eau depuis un bateau en marche, le bateau peut s'arrêter sur une position peu éloignée de la personne tombée à l'eau, et peut informer le reste des passagers du bateau.
