Sudden water pollution accident analog simulation and visualization service system

Abstract

The invention discloses a sudden water pollution accident analog simulation and visualization service system. The system is characterized in that a B / S (browser / server) structure is adopted, an analog simulation computing service of sudden water pollution accidents is provided at a server side, simulation prediction of pollutant diffusion trend is performed by the aid of a water power model and a water quality model according to water quality and hydrological monitoring data, sudden accident information and pollutant information, and simulation results are stored into a database; and the simulation results are associated with space information by means of the WebGIS technique, and spatial and temporal change dynamic effects of sudden water quality pollution accidents are presented in a GIS (geographic information system) map form on a client browser and used for emergency disposal and decision support for the sudden water quality pollution accidents. The sudden water pollution accident analog simulation and visualization service system is available for remote operation and network access, meets the current requirements on rapid and effective analog simulation services of sudden water pollution accidents, and can provide services for various water environmental monitoring systems and water quality monitoring early warning systems.

Description

technical field [0001] The invention belongs to the interdisciplinary field of environmental hydraulics, geographic information technology and computer digital simulation, and relates to a simulation and visualization service system construction method for sudden water pollution accidents, in particular, it refers to a combination of WebGIS technology and hydraulic simulation Technology builds a network service system to provide dynamic simulation services for sudden water pollution accidents and visual display services. The system can provide effective support and services for water environment monitoring and water quality safety assurance. Background technique [0002] The safety of drinking water is related to the health, life safety and social harmony and stability of the broad masses of the people. In recent years, the frequent occurrence of water pollution incidents has aroused great public concern. The city's response speed and decision-making ability to sudden wate...

Problems solved by technology

[0011] The technical problem to be solved by the present invention is: to overcome the deficiency that the existing water quality simulation software is limited to local operation and unable to provide networked services, and to provide a sudden water pollution accident simulation and visualization service system that supports remote operation. The system can establish a self-service remote simulation service for sudden water pollution accidents without geographical restrictions. Users input accident information, pollutant information, simulation model parameters, etc. on the browser side, and the server side automatically runs the simulation according to the user's configuration. Simulation calculation, the calculation results are returned to the user's browser, and combined with spatial information, a visual display is provided in the form of a map
