Fault tree construction and management method based on Internet of Things structure

The invention relates to the technical field of airborne electronic equipment maintenance fault diagnosis, in particular to a fault tree construction and management method based on an internet of things structure, which comprises the following steps of: (1) constructing the internet of things structure based on an airborne electronic equipment BOM (Bill of Maintenance) structure through a template, node addition and measurement point/measurement quantity addition; (2) based on the Internet of Things structure in the step (1), a historical inspection and maintenance report and troubleshooting experience, uploading and adding fault types through a template to define a fault tree structure; (3) based on the fault tree structure in the step (2), uploading historical detection data, accessing the historical detection data into the system, and realizing management of databases in a historical normal mode and a fault mode; and step (4), realizing root cause association of the fault types of different Internet of Thi
