Abstract

Procédé de surveillance d'une connexion de communication, système médical (100) et support de stockage, associés au domaine des technologies médicales. Le procédé consiste : après l'établissement d'une connexion de communication entre un ordinateur supérieur (101) et un ordinateur inférieur (102), à écrire périodiquement, par l'ordinateur supérieur (101), des chiffres de fréquence cardiaque sur l'ordinateur inférieur (102), les chiffres de fréquence cardiaque écrits sur l'ordinateur inférieur (102) à chaque fois étant différents (201) ; si l'ordinateur supérieur (101) échoue à écrire les chiffres de fréquence cardiaque sur l'ordinateur inférieur (102) au moins une fois, à déterminer, par l'ordinateur supérieur (101), que la connexion de communication entre l'ordinateur supérieur (101) et l'ordinateur inférieur (102) est anormale (202) ; à lire périodiquement, par l'ordinateur inférieur (102), les chiffres de fréquence cardiaque écrits par l'ordinateur supérieur (101) (301) ; et si les chiffres de fréquence cardiaque lus par l'ordinateur inférieur (102) au moins deux fois à la suite sont identiques, à déterminer, par l'ordinateur inférieur (102), que la connexion de communication entre l'ordinateur inférieur (102) et l'ordinateur supérieur (101) est anormale (302). Grâce au procédé de surveillance d'une connexion de communication, il peut être garanti que lorsque le système médical (100) fonctionne, l'ordinateur supérieur (101) peut surveiller si la connexion de communication entre l'ordinateur supérieur (101) et l'ordinateur inférieur (102) est normale ou non en temps réel, et l'ordinateur inférieur (102) peut surveiller si la connexion de communication entre l'ordinateur inférieur (102) et l'ordinateur supérieur (101) est normale ou non en temps réel.
