Mesh-based flood control command studying and judging system

Abstract

The invention discloses a mesh-based flood control command studying and judging system. The system comprises the steps that firstly, mesh generation is performed in an area under administration at first, meshed are adopted as units, and one or more water and rainfall condition information monitoring stations are arranged in each mesh; the water and rainfall condition information monitoring stations inside each mesh transmit current water and rainfall condition data to the system in real time; the water and rainfall condition data of the corresponding meshes is input into a hydrological prediction model for performing prediction analysis, and future rainfall predication data of each mesh is obtained; similarity analysis is performed through the flood control command studying and judging system, and historical water and rainfall condition data with the highest similarity with the current water and rainfall condition data inside the corresponding meshes is obtained; the current water and rainfall condition data, the historical water and rainfall condition data with the highest similarity with the current water and rainfall condition data and the future rainfall predication data of each mesh, socioeconomic data and basic level flood control system data are visually displayed in a GIS map through the flood control command studying and judging system. By mesh generation of the area under administration, the multiple meshes are formed, and the flood control early warning is more visualized.

Description

technical field [0001] The invention is a grid-based flood control command research and judgment system. Background technique [0002] Flood control and disaster reduction measures mainly include engineering measures and non-engineering measures. Engineering measures are unanimously favored by people due to their significant benefits in flood control and disaster reduction. All countries have spared no effort in building embankments, reservoirs and other flood control projects to improve flood control standards. But on the one hand, there is a huge investment in flood control projects; on the other hand, the frequency of unstoppable floods is increasing, and flood losses continue to rise. Non-engineering flood control measures are to reduce disasters or mitigate possible losses caused by disasters through non-engineering measures such as flood forecasting, flood control dispatching, flood diversion, flood detention, legislation, flood insurance, and floodplain management. ...

AI Technical Summary

Problems solved by technology

[0007] (1) When the flood control command and decision-making system based on the GIS platform is in the emergency state command and decision-making, it often only pays attention to the overall distribution information on the large area or the detailed information on the point in the administrative area, but the disaster events during the disaster often occur in a certain area. Therefore, the flood control command and decision-making system based on the GIS platform cannot carry out targeted analysis, command and judgment

[0008] (2) Since the GIS-based flood control command and decision-making system can only present information on the overall surface and information on points, the network analysis of related connection points cannot be carried out, and the relevant information in the cells can be analyzed by using grids as cells. Relate, compare and present

[0009] (3) For consultations during disaster weather, it is necessary to grasp historical, current and future information. At present, most of the systems can realize the dynamic grasp of real-time information. Due to the limitations of objective conditions, there are often certain deviations in future rainfall and flood forecasts. However, historical information, as definite information, often plays a vital role in research and judgment during disasters. Currently, existing systems often simply list historical data and fail to intelligently perform similarity analysis, presenting users with high similarity and useful references.
