Abstract

L'invention concerne un système de surveillance de pression de pneumatique (10) qui comprend : un capteur de pression de pneumatique (101) ; un hôte (102) connecté au capteur de pression de pneumatique (101) ; et un client (103) connecté sans fil à l'hôte (102). L'hôte (102) comprend un module d'évolution à long terme pour l'Internet des objets (LTE-M) (1021). Le capteur de pression de pneumatique (101) est utilisé pour détecter une pression de pneumatique d'un pneumatique d'un véhicule et transmettre la pression de pneumatique à l'hôte (102). L'hôte (102) est utilisé pour déterminer si la pression de pneumatique du véhicule est anormale ou non. Si la pression de pneumatique est anormale, le module LTE-M (1021) transmet la pression de pneumatique et/ou des informations d'avertissement au client (103). L'invention concerne également un procédé de surveillance de pression de pneumatique destiné à être utilisé dans un hôte, un procédé de surveillance de pression de pneumatique destiné à être utilisé dans un serveur en nuage, et un support de stockage informatique.
