A Hazard Prediction and Control System for Hazardous Chemical Transportation

Abstract

The invention provides a transportation of dangerous chemicals hazard prediction and control systems, along with its proposed model is based on CAMx diffusion model building, taking into account the influence of meteorological factors, topography factors, the actual diffusion more relevant; it will be accompanied by mode from conservation goals, only one adjoint equation solving can get value at risk, solving the adjoint equation of time and the time to solve the diffusion equation is considerable; it provides a numerical diffusion model forecast imminent risk of transportation of hazardous chemicals, considering transport objects, actual transit time and transportation routes, draw the fine distribution of the actual risk field of transport, to avoid the blindness of emergency preparedness, which provides a combination of actual terrain, weather, and other environmental hazards in real-time, real-time match when evaluation mode, so that dangerous chemicals transportation accident hazard control more scientific and effective. Therefore, the present invention harm predictions more accurate, more efficient hazard prediction efficiency, hazard control decision-making 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
