Fault diagnosis map construction method and related device

The invention provides a fault diagnosis atlas construction method applied to data processing equipment and a related device, and the method comprises the steps: constructing a first diagnosis atlas based on maintenance information of maintenance personnel, obtaining a second diagnosis atlas through mining state time sequence data when industrial equipment works, and then obtaining a fault diagnosis atlas; and fusing the first diagnosis atlas and the second diagnosis atlas through the fault entity node to obtain a fault diagnosis atlas. The explicit fault relationship easy to be found by the maintainer is recorded in the first diagnosis map, and the implicit fault relationship difficult to be found by the maintainer is recorded in the second diagnosis map, so that the explicit fault relationship and the implicit fault relationship are fused to construct a logic relationship between the explicit fault relationship and the implicit fault relationship; therefore, the fault diagnosis atlas is more accurate and co
