Method, device, system and storage medium for fault diagnosis and solution recommendation

A device for fault diagnosis and solution recommendation, the device comprising:

• a data obtaining module, to obtain original data including fault problem of a target device, wherein the original data includes an error signal generated by the target device, the original data comprising a data stream with device identification and time information;
• a fault analysis module, to analyze the original data to obtain problem description information including obtaining a task document from a cloud task management database according to the device identification and time information, wherein the cloud task management database stores task documents comprising the standard processes and steps of each task of each device;
• a fault diagnosis module, to analyze the problem description information to obtain a diagnosis report, comprising:
• dividing the data stream into corresponding data segments according to the standard processes and steps in the task document;
• determining a target step with a fault by locating an error signal in a data segment;
• and
• comparing the part corresponding to the target step in the task document with that in the data stream, analyzing a fault reason based on the comparison, and generating the problem description information;
• and
• a solution recommendation module, to obtain obtaining a video and/or document solution for the fault based on a cloud knowledge map according to the diagnosis report, and to recommend the video and/or document solution to a user,
• wherein the original data comprises data stream with a device identification and time information, and/or fault multimedia content, and the fault multimedia content comprises:
• a video containing fault process or a photo containing fault area,
• and wherein the fault analysis module comprises a data stream analysis module and/or a multimedia content analysis module;
• the data stream analysis module is further programmed to obtain a task document from a cloud task management database according to the device identification and time information;
• the cloud task management database stores task documents comprising the standard processes and steps of each task of each device, and
• divide the data stream into corresponding data segments according to the standard processes and steps in the task document.
