Electromechanical system logical relationship generation method and device and building information model

Abstract

The invention discloses an electromechanical system logical relationship generation method and device and a building information model. The method includes: a conversion step, namely converting a physical relationship between pipeline components and electromechanical devices in a to-be-processed building information model into a corresponding topological relationship; a separation step, namely separating electromechanical device representing device nodes and pipeline component representing pipeline nodes in the topological relationship to obtain more than one subgraph acquired based on pipeline node splitting, wherein each subgraph represents pipeline groups in connection with one electromechanical device; a logic establishment step, namely establishing a logic connection relationship of different electromechanical devices according to an association relationship of different electromechanical devices connected to a same pipeline group. By adoption of the scheme, the logic connection relationship can be generated according to physical connection information, and accordingly fault positioning efficiency of the building information model in an operation and maintenance operation is improved.
