[摘 要]文章为有效处理储油罐变位标识以及罐容表标定相关问题,经由对储油罐横向偏转以及纵向倾斜带给罐容表影响表现的方式,构建获得罐体变位的情况下,实际储油量以及显示油位高度两者的分析模型。其中,针对变位标识问题,能够经由定积分的方式来实现横截面顺着罐体底面来完成积分作用的方式构建并且检验储油罐v以及油位高度h相关的初始模型。同时,参照绝对误差以及油位高度情况完成拟合分析,获得补偿函数f(x),将其与初始模型完成组合作用的情况下,能够获得修正完成罐容表后对应着的标定模型;针对罐容表标记问题,考虑到储油量的体积就是球罐以及圆柱体两者油量体积的综合,前者经由球冠蒙塔卡罗法(样本量N=100000)完成求解,如此就能够获得油位以及变位相关参数关系。

Displacement Identification and Tank Capacity Table Calibration of Oil Storage Tank
You Zi-ming
[Abstract]In order to effectively deal with the problems related to the tank displacement identification and tank capacity meter calibration, this paper constructs the analysis model of the actual oil storage capacity and the displayed oil level height under the condition of tank displacement by analyzing the influence of the lateral deflection and longitudinal tilt of the tank on the tank capacity meter. Among them, for the problem of displacement identification, we can achieve the integration of cross section along the bottom of the tank through definite integration, build and test the initial model of oil tank V and oil level height H. At the same time, according to the absolute error and oil level height, the fitting analysis is completed, and the compensation function f (x) is obtained; Considering that the volume of oil storage is the combination of the volume of oil storage of spherical tank and cylinder, the former is solved by ball crown montakaro method (sample size n = 100000), so that the relationship of oil level and displacement related parameters can be obtained.

1.1 背景
一般加油站内安排着若干数量用以完成燃油储存作用的地下储油罐,还有着与其功能实现相适合的“油位计量管理系统”,能够基于流量计等方式确定油罐里面的油位高度变化情况,借助事先完成标定作用的罐容表来完成实时的计算分析,以便能够把握油罐里面油位高度值与其储油量两者呈现的改变表现。但是,很多储油罐在操作相当时间的情况下,考虑到地基变形等相关因素的影响,会存在着横向偏转以及纵向倾斜等相关问题,进而使得罐容表无法完整地将油位变化信息展现出来。……
