The invention discloses a counting and acquisition terminal fault diagnosis and visualized positioning method based on clustering analysis and belongs to the technical field of acquisition terminal fault positioning. According to the invention, by widely extracting and filtering data of an electricity utilization information acquisition system, clustering analysis and classification is adopted for acquisition data and history file information of a counting terminal, so an acquisition terminal fault diagnosis and classification result is formed and terminal fault information points are screened. According to the geographic coordinate of the acquisition terminal fault information points, fault positioning is performed on geographic space information data. Tracking and visualized displaying of the acquisition terminal fault information points are achieved on a GIS map, so real-time data monitoring, fault diagnosis and visualized positioning of the acquisition terminal are achieved.
