Abstract: At present, the problems of unclear definition and inconsistent understanding exist in the construction of intelligent pipeline network.Based on the definition of intelligent pipeline network proposed in the existing literatures, the following definition of intelligent pipeline network was given from the functions that the intelligent system should have in the four aspects of perception, analysis, decision-making and disposal.Intelligent pipeline network refers to the comprehensive intelligent perception, independent analysis and calculation of the pipeline state by making full use of information technology and artificial intelligence technology on the premise of minimizing the physical and intellectual activities of people in the operation of the pipeline network.Therefore, it has the ability of independent decision-making and disposal of various production needs and abnormal events in the operation of the pipeline network, allowing a quick, flexible and accurate judgment and response to the safety and operation status of the pipeline network, thus achieving the goals of the highest safety and environmental protection level and the best operation benefit in the full life cycle of the pipeline network.Referring to the five elements of intelligent dimension in the maturity model of intelligent manufacturing capability and the existing research results of intelligent pipeline network, the five characteristics of intelligent pipeline network were cleared, i.e., business intelligentization, data unification, information intercommunication, state visualization and knowledge networking.Based on this, the construction conception of intelligent pipeline network was put forward.
