一种原油储罐界面参数的快速检测方法及其实现

摘要

In order to solve the problems of data processing in measuring interface parameters of crude oil storage tank, an interface parameter analysis method based on the inflection point detection principle of recursive CUSUM sequence data was proposed.The method has the interface parameter measuring instrument employed to collect sequence data, calls inflection point algorithm recursively based on CUSUM of the sequence data, and has the characteristics of the inflection point data taken as the demarcation point of various mediums in the oil tank so as to determine specific information of multi-level interface parameters.%针对原油储罐多液位界面参数测量中数据处理存在的问题,提出了基于递归累积和序列数据拐点检测原理的界面参数分析方法.该方法利用多液位界面参数测量仪采集的序列数据,递归地调用基于累积和的序列拐点检测算法,利用拐点数据的特性作为储罐内部多种介质的分界点,从而判定多液位界面参数的具体信息.
