Abstract

L'invention concerne un système de surveillance de sécurité et un procédé de surveillance de sécurité d'un siège de sécurité pour enfant. Le système est principalement composé d'un module d'acquisition d'état, d'une unité de commande de siège de sécurité, d'un module de commande de sécurité, d'une plateforme de traitement de données de réseau et d'une extrémité d'exploitation mobile. Dans la présente invention, l'état d'assise et les signes vitaux d'un enfant courant, ainsi qu'un état ambiant dans un véhicule, sont analysés et surveillés sur la base de la collecte de données de capteur d'un siège de sécurité pour enfant ; et en même temps, les fonctions suivantes sont fournies : premièrement, la collecte de l'état d'un enfant à l'intérieur d'un véhicule, la détermination du fait que l'enfant est en danger ou non et la notification à des gardiens (plusieurs personnes qui tiennent un terminal mobile et qui ont accès à celui-ci) de l'état par l'intermédiaire d'un terminal Internet ; et deuxièmement, l'élimination, au moyen des informations de collecte de données du siège de sécurité pour enfant et par l'intermédiaire d'un traitement d'extrémité en nuage ou par le biais d'une commande sur l'ensemble du véhicule au moyen d'un ordinateur embarqué (fonctions telles que l'ouverture et la fermeture d'une fenêtre, l'activation d'un climatiseur, l'ouverture d'un toit ouvrant, le freinage du véhicule, le clignotement d'une lampe de véhicule et l'avertissement sonore), des dangers et des risques cachés pour les enfants dans la voiture, et l'émission simultanée d'une alarme.
