Short-term wind speed calculation method based on hazardous chemical accident diffusion model

Abstract

The invention discloses a short-term wind speed calculation method based on a hazardous chemical accident diffusion model. The short-term wind speed calculation method comprises the following steps of by combining an ABC (artificial bee colony) algorithm and a BP (back propagation) nerve network, optimizing the weight and threshold value of the BP nerve network by the ABC algorithm, accurately predicting the wind speed, and quickly and efficiently performing accurate evaluation on the influence degree and influence range of hazardous chemical leakage accidents in a chemical industrial park. Compared with a PSO-BP (particle swarm optimization-back propagation) nerve network and a GA-BP (genetic algorithm-back propagation) nerve network, the short-term wind speed calculation method has the advantages that the predicting accuracy is obviously improved, the high-efficiency predicting is realized, and the economic cost is reduced; the predicting accuracy on short-term wind speed is improved, and the error rate is only 1.82%; the site accidents can be effectively treated, the emergency rescue and high-efficiency population evacuation can be quickly performed, and the personal casualty and economic loss in the accidents are decreased.

Description

technical field [0001] The invention relates to the technical field of emergency communication, in particular to a short-term wind speed calculation method based on a hazardous chemical accident diffusion model. Background technique [0002] With the rapid development of industrial technology, the use of hazardous chemicals (hazardous chemicals) is increasing, and in all links of production, transportation, storage and use of hazardous chemicals, leakage accidents of hazardous gases are extremely prone to occur. Some hazardous chemical gases are extremely toxic and diffusible. Once such an accident occurs, it will have a serious impact on the ecological environment and personal safety in the surrounding area, resulting in major economic losses, which is not conducive to the protection of the ecological environment and life safety. And the continuity of smooth production in industry. At the leakage site of toxic and hazardous chemical gases, controlling gas diffusion based o...
