Abstract
Le système de surveillance comporte un ensemble de détection (1) qui peut être facilement positionné sur une surface plane tel que le sol, notamment à proximité d'un lit, et qui peut être facilement déplacé. Cet ensemble de détection (1) comporte une pluralité de capteurs (Bi) qui sont chacun aptes à délivrer un signal électrique de détection qui est caractéristique de la force exercée sur ledit capteur. Le système de surveillance comporte en outre des moyens électroniques de traitement (2) qui sont aptes, à partir des signaux électriques de détection délivrés par les capteurs (Bi), à détecter automatiquement le passage d'un individu sur l'ensemble de détection (1) et à déclencher une alerte en cas d'absence de détection de deux passages successifs sur l'ensemble de détection (1) dans un délai prédéfini (DELAI_RETOUR).The monitoring system includes a detection assembly (1) that can be easily positioned on a flat surface such as the floor, particularly near a bed, and that can be easily moved. This detection assembly (1) comprises a plurality of sensors (Bi) which are each capable of delivering an electrical detection signal which is characteristic of the force exerted on said sensor. The monitoring system further comprises electronic processing means (2) which are able, from the electrical detection signals delivered by the sensors (Bi), to automatically detect the passage of an individual over the detection unit ( 1) and to trigger an alarm if there is no detection of two successive passes on the detection assembly (1) within a predefined time (DELAY_RETURN).
