Abstract

Procédé et appareil de commande d'inspection de patrouille pour une unité d'inspection de patrouille, et dispositif électronique. Le procédé consiste : à acquérir des informations de disposition d'installation d'une installation cible, et à effectuer une division en fonction des informations de disposition d'installation afin d'obtenir au moins deux zones d'inspection de patrouille (S101) ; à calculer une densité de rail de suspension de chaque zone d'inspection de patrouille, et à déterminer une vitesse d'inspection de patrouille correspondant à chaque densité de rail de suspension (S102) ; et à commander à une unité d'inspection de patrouille de se déplacer selon un trajet d'inspection de patrouille prédéfini, et à maintenir la vitesse en cours de l'unité d'inspection de patrouille en tant que vitesse d'inspection de patrouille correspondant à la zone d'inspection de patrouille en cours (S103). Différentes zones d'inspection de patrouille sont divisées en fonction de l'état de disposition réel d'une installation. Différentes vitesses d'inspection de patrouille sont définies pour différentes zones d'inspection de patrouille, et pour une zone d'inspection de patrouille présentant une complexité supérieure, la vitesse d'inspection de patrouille d'une unité d'inspection de patrouille est inférieure, ce qui permet d'assurer que l'unité d'inspection de patrouille effectue une inspection de patrouille relativement suffisante sur chaque ligne de production tout en garantissant l'efficacité d'inspection de patrouille de l'unité d'inspection de patrouille, ce qui permet d'éviter la situation dans laquelle une anomalie de la ligne de production ne peut pas être détectée en raison d'une vitesse de déplacement trop élevée, et ainsi l'effet d'inspection de patrouille est bon.
