Abstract

The invention discloses a fault diagnosis method and system, and the system comprises the steps: obtaining a fault circuit diagram set corresponding to a fault; traversing the fault circuit diagram set to obtain a matched circuit diagram, wherein the matched circuit diagram is a fault circuit diagram with the highest matching degree with the fault in the fault circuit diagram set; and obtaining the cause of the fault according to the matched circuit diagram. According to the invention, the fault circuit diagram set which describes the corresponding relation between the fault and a fault pointis used for searching and locating the cause of the fault, so the method and system can achieve the modeling and automation of the fault diagnosis, and achieves the high-efficiency fault diagnosis capability.

Description

technical field [0001] The invention relates to a fault diagnosis method and a fault diagnosis system of a direct broadcast satellite user management system. Background technique [0002] In the prior art, when a failure occurs in the direct broadcast satellite user management system, it is difficult to quickly find the cause of the failure.
