Abstract: A method for processing an operating state of a high-pressure manifold, includes: determining a connection diagram of the high-pressure manifold, and the connection diagram is a line diagram formed by a plurality of device nodes; obtaining manifold data from a start node to an end node in the line diagram, and the manifold data includes flow parameters of a fluid in the high-pressure manifold; and determining the operating state of the high-pressure manifold according to the manifold data.
