A Hazard Prediction and Control System for Hazardous Chemical Transportation

Abstract

The invention provides a hazardous chemical transport hazard predicting and controlling system. The adjoint mode provided by the hazardous chemical transport hazard predicting and controlling system is set up on the basis of a CAMx diffusion mode and is more suitable to practical diffusion by considering affection of meteorological factors and topographic factors; starting from protective targets, the adjoint mode only needs to solve adjoint equation once to acquire risk value, and time for solving the adjoint equation is equal to time for solving diffusion equation; prediction of hazardous chemical transport coming risks is realized by application of the numerical diffusion mode is realized, practical conditions of transport objects, transport time and transport lines are comprehensively considered, elaborate risk field distribution during practical transport is obtained, blindness of emergency preparation is avoided, and a real-time hazard evaluation mode matched with actual topography, weather, environments and the like is provided, so that hazard control during hazardous chemical transport accidents is more scientific and effective. Accordingly, hazard prediction results are more accurate, hazard prediction efficiency is higher, and hazard control policy is more scientific.

Description

technical field [0001] The invention belongs to the field of chemical safety, and relates to a hazardous chemical transportation hazard prediction and control system. Background technique [0002] Statistics show that a large number of dangerous goods accidents occurred during the transportation process, and the hazard prediction and prevention of chemical dangerous goods transportation is a major technical problem. Of the 3,222 accidents involving dangerous chemicals that occurred in Europe from 1926 to 1997, 41% occurred during transportation; the proportion of transportation accidents among dangerous goods accidents in major cities in my country reached 32% from 2002 to 2004. [0003] As a mobile risk source, the transportation of hazardous chemicals poses a huge threat to the population, environment and economy along the transportation route. Once a transportation accident occurs, the casualties and property losses caused by the traffic accident itself are not the main ...

Problems solved by technology

On March 29, 2005, a traffic accident on the Huai'an section of the Beijing-Shanghai Expressway caused a large amount of liquid chlorine leaked from the vehicle, killing 29 people and seriously injuring 456. More than 10,500 villagers were forced to evacuate, causing a direct economic loss of more than 17 million yuan

There are many risk factors in the transportation of dangerous chemicals, multiple risks interact, and the risks are difficult to quantify

The selection and optimization of transportation roads are directly related to the natural and human environment such as weather, terrain, nature of the underlying surface, population and distribution of important targets, and the meteorological conditions change with time and space. Since the source of danger in the transportation of chemical dangerous goods also moves with time and space, The optimization of transportation roads is an inverse problem, and its model establishment and solution are very complicated
