Abstract

La présente invention concerne un capteur sismique intelligent. Le capteur sismique intelligent comprend un dispositif de collecte de données et un dispositif d'alimentation électrique pour fournir de l'électricité au dispositif de collecte de données, et le dispositif de collecte de données est connecté de façon détachable au dispositif d'alimentation électrique. Le dispositif de collecte de données comprend une première enveloppe, un détecteur et un panneau de commande. Le dispositif d'alimentation électrique comprend une deuxième enveloppe, une deuxième cavité de réception est formée par la deuxième enveloppe, et la première enveloppe est reliée de façon détachable à la deuxième enveloppe. Le dispositif d'alimentation électrique comprend en outre une alimentation électrique, et l'alimentation électrique est reçue dans la deuxième cavité de réception, reliée de façon fixe à la deuxième enveloppe, et électriquement connectée au panneau de commande et au détecteur. Le dispositif d'alimentation électrique comprend en outre une interface d'extension externe, et l'interface d'extension externe est formée sur la deuxième enveloppe. Le capteur sismique intelligent comprend en outre un panneau adaptateur, et le panneau adaptateur est électriquement connecté au panneau de commande, au détecteur et à l'interface d'extension externe, séparément. L'objectif de la solution technique de la présente invention est de résoudre le problème technique de l'inconvénient de transporter un capteur sismique intelligent existant dans un processus d'opération sur site, ce qui perturbe la construction.
