Embodiment 1

[0017] The present invention utilizes machine learning technology and method to realize the parameter training and parameter learning of the urban accident disaster machine learning fast prediction model by using various data to construct the urban accident disaster evolution data warehouse. The machine learning fast prediction model will pass the video surveillance data, The analysis and calculation of real-time monitoring data of sensors can realize the rapid prediction and early warning of urban accident and disaster risks. Among them, the urban accident disaster evolution data warehouse includes various types of data as follows:

[0018] 1. Real-time monitoring data of various sensors in the city;

[0019] 2. Historical data of various accidents and disasters;

[0020] 3. Experimental data of various urban accidents and disasters;

[0021] 4. High-confidence numerical simulation data of various urban accidents and disasters.

[0022] The data warehouse established in th...

Embodiment 2

[0026] figure 2 It is a structural block diagram of an embodiment of the present invention, which realizes the disaster evolution simulation and risk prediction and early warning of gas leakage accidents in urban underground utility tunnels. Based on the existing experimental data of gas leakage in the comprehensive pipeline gallery and the numerical simulation data of gas leakage in the comprehensive pipeline gallery with high confidence, a data warehouse of gas leakage accidents in the cabin of the comprehensive pipeline gallery can be established. Among them, the numerical simulation data of gas leakage in the comprehensive pipeline gallery with high confidence is generated through two types of models: 1. The numerical simulation model of gas leakage and diffusion in the comprehensive pipeline gallery verified by experimental data or historical data of accidents and disasters; Gas leakage source estimation and diffusion prediction correction model for pipe gallery. Based ...

Abstract

The invention discloses a city accident disaster evolution simulation and risk prediction and early warning method, which belongs to the technical field of machine learning. By establishing an urban accident and disaster data warehouse that integrates multiple types of data, using machine learning methods to construct urban accident and disaster evolution simulation and risk prediction and early warning machine learning prediction models, to achieve rapid and accurate prediction of accident and disaster evolution and rapid prediction and early warning of accident and disaster risks . The data warehouse integrates historical data of urban accidents and disasters, experimental data of urban accidents and disasters, real-time monitoring data of various sensors, and high-confidence numerical simulation data of urban accidents and disasters evolution. Among them, the numerical simulation data of urban accident and disaster evolution with high confidence is generated by a numerical simulation model verified by historical accident disaster data or experimental data, or by a numerical simulation model based on data assimilation technology that fuses a numerical simulation model with historical accident data or experimental data , to solve the problem of insufficient data in the data warehouse.

Description

technical field [0001] The invention specifically relates to a method for urban accident disaster evolution simulation and risk prediction and early warning, and belongs to the technical field of machine learning. Background technique [0002] In recent years, with the rapid development of my country's economy and society, the level of urbanization has been continuously improved. However, due to the acceleration of urbanization and the deterioration of the natural environment, the rapid increase of disaster-causing factors and the frequent occurrence of urban accidents and disasters in our cities have led to a very severe form of urban public security in our country. At present, there are various types of urban accident disasters, which have the characteristics of diversity, coupling and chaining. At the same time, due to the characteristics of urban population concentration and dense buildings, if urban accidents and disasters cannot be predicted, early warning and emergen...
