基于LabVIEW的码头管道危险性动态分级研究

A Research for the Dynamic Classification of Pipeline Risk Level in Wharf Based on LabVIEW

为了有效、合理地对码头管道进行分级管理,本文设计了一种在LabVIEW环境中基于DT法的码头管道危险性动态分级系统。该系统通过模拟码头管道危险物质泄漏造成的事故后果,计算出11种事故后果伤害参数作为分级指标,并将这11种分级指标代入DT动态分级模型进行计算,可快速得到码头管道的危险性等级。通过将该系统应用于实际码头管道危险性分级,仿真模拟结果表明:这种在LabVIEW环境中基于DT法的码头管道危险性动态分级系统可以快速、有效、准确地实现码头管道危险性的实时动态分级,可为码头安全管理提供重要的依据,同时LabVIEW的应用也避免了复杂的人工计算。

In order to rationally and effectively grade the risk levels of pipelines in wharf,this paper introduces a new dynamic classification system of pipeline risk level based on DT method in the LabVIEW environment.On the basis of the analysis and simulation of the leakage consequences of pipelines in wharf,the system calculates 11 kinds of accident parametersas classification index,and inserts the index into DT method for the classification of pipelines.The application of this system can obtain risk levels quickly.The study applies the developed system to the actual situation and the simulation experiment results indicate that this new DT dynamic classification system can determine the risk levelsof pipelines quickly,effectively and accurately,which provides some reference for the safety management of wharf.Also,the application of LabVIEW environment can avoid complicated manual calculation.
