Abstract

The invention discloses a liquid leakage accident simulation deduction method and device based on a geographic information system (GIS). The method comprises: acquiring a liquid-pipeline cleft area, height of a liquid level at a cleft, density of leaked liquid, liquid pressure in a liquid pipeline and environment pressure of the liquid pipeline, and determining a liquid leakage coefficient according to a liquid-pipeline cleft shape; calculating mass flow of the leaked liquid; acquiring liquid leakage duration; calculating mass of the leaked liquid according to the mass flow of the leaked liquid and the liquid leakage duration; and calculating a leakage radius of the liquid according to the liquid pressure in the liquid pipeline, the mass of the leaked liquid and the liquid leakage duration, and displaying an influence range of current liquid leakage in a three-dimensional map of the geographic information system according to the leakage radius of the liquid. The device includes a firstacquisition module, a first calculation module, a second acquisition module, a second calculation module, a third calculation module and a first deduction module. The method and the device provide more intuitive reference information.

Description

technical field

[0001] The invention relates to the field of information technology, in particular to a liquid leakage accident simulation and deduction method and device based on a geographic information system. Background technique

[0002] Oil transportation is divided into land transportation and sea transportation. Land transportation mainly adopts pipeline transportation, which has the advantage of good timeliness and is not restricted by day, night and weather, but has poor flexibility. Sea transportation mainly adopts large oil tankers and other transportation methods. The advantage of sea transportation is that it is low in cost and large in volume, but it takes a long time.

[0003] In the transportation process using pipelines, in order to prevent hidden dangers caused by pipeline defects, various manufacturers have adopted various emergency response systems. The emergency response system currently used in the petroleum industry can provide specific information ...
