Chemical industry park hazard situation awareness method and system based on multi-source data fusion

Abstract

The invention relates to a chemical industrial park hazard situation awareness method and system based on multi-source data fusion. The chemical industrial park hazard situation awareness method comprises the steps: carrying out the grid segmentation of a chemical industrial park, and forming a plurality of grid points; based on the actual distance, the accident consequence calculation model and the relative danger degree, constructing a danger coefficient evaluation model between each danger source and any grid point in the chemical industry park; determining the weight of the danger coefficient of each danger source at any grid point according to the dangerous goods real-time monitoring data of each danger source and a preset alarm threshold; and according to the weight, carrying out weighted superposition on the danger coefficient of each danger source at any grid point to obtain the danger situation of any grid point in the chemical industry park. According to the chemical industrial park hazard situation awareness method, whether danger occurs can be sensed, and the distribution of the danger degree of the chemical industrial park can be sensed when danger occurs, and the sensing capability of the chemical industrial park in the aspects of danger situation and dangerous area distribution can be improved, and the danger is prevented.

Description

technical field [0001] The invention relates to the field of dangerous situation analysis in chemical industry parks, in particular to a method and system for perceiving dangerous situations in chemical industry parks based on multi-source data fusion. Background technique [0002] The analysis of the danger situation in the chemical industry park is the guarantee of the safety of the chemical industry park. The existing analysis of the danger situation in the chemical industry park mainly adopts the following three methods: 1. Early warning analysis through the alarm threshold of the sensor; 2. Analysis through the estimated concentration of the gas diffusion model; 3. , Estimate the destructive force through the explosion model for analysis, where: [0003] 1. Carry out early warning analysis through the sensor alarm threshold [0004] This technical solution uses the monitoring values ​​of the sensors (such as pressure sensors, liquid level sensors, and temperature senso...

AI Technical Summary

Problems solved by technology

[0014] a Dangerous situation awareness method is single; for example, when dangerous situation awareness is carried out through the sensor alarm threshold, the park manager can only obtain the information of whether there is danger in the park through the sensor, but cannot have a more intuitive view of the degree of harm that the dangerous source may cause cognition

When the hazard range is estimated by the gas diffusion model or the explosion model, due to the different dimensions of the estimated values ​​of the two models, the degree
