Abstract

The invention belongs to the technical field of urban waterlogging meteorological prediction, and specifically provides an urban waterlogging warning device and method based on precipitation forecast, wherein the device comprises: a data acquisition module for acquiring urban meteorological data and urban drainage and waterlogging prevention standards; data processing The module is used to generate the cumulative value of 24-hour precipitation according to the meteorological data, and the cumulative value of 24-hour precipitation is arranged in time series; the data analysis module is used to obtain the urban waterlogging according to the cumulative value of 24-hour precipitation and the urban drainage and waterlogging prevention standard A risk factor, the urban waterlogging risk factors are arranged in time series; a risk early warning module is used to generate an urban waterlogging warning according to the urban waterlogging risk factor. Through the above device, it is possible to provide waterlogging warnings for cities in the country based on urban administrative divisions, and then provide suggestions for urban construction departments, water conservancy departments, etc., to improve their defense efficiency.

Description

technical field [0001] The invention belongs to the technical field of urban waterlogging meteorological prediction, and specifically provides an urban waterlogging warning device and method based on precipitation forecasting. Background technique [0002] Urban waterlogging refers to the phenomenon of water accumulation in cities due to heavy or continuous precipitation exceeding the drainage capacity of the city. At present, my country's urbanization is developing rapidly, and among the many effects that follow, there are many factors that exacerbate the flooding of the streets during the flood season. Urban water accumulation has caused damage to public facilities, seriously affected or damaged transportation, electricity, communication, network transmission, and water sources, and brought a lot of inconvenience to people's production and life. In addition, with the increase in the density of urban population and assets, the loss increases under the same inundation condi...
