Gathering and transportation pipeline circulation state monitoring method and system based on statistical mode analysis

Abstract

The invention relates to the technical field of gathering and transportation pipeline circulation state monitoring, and particularly discloses a gathering and transportation pipeline circulation state monitoring method and system based on statistical mode analysis, and the method comprises the steps: constructing a statistical mode principal component analysis model; calculating the control limit of the monitoring statistics of each state; acquiring monitoring data of the gathering and transportation pipeline, and calculating to obtain monitoring statistics of the monitoring data by using the statistical mode principal component analysis model; and based on the control limit of the monitoring statistical magnitude of each state, performing decision fusion by using Bayesian reasoning according to the monitoring statistical magnitude of the monitoring data, and calculating to obtain the current state of the gathering and transportation pipeline. According to the method, a model of three states including a normal state and two hydrops states is established, monitoring statistics are calculated by utilizing principal component characteristics of the three states, Bayesian reasoning is carried out, a final visual state monitoring index is obtained, and the state of the current process is accurately judged.
