Embodiment 1

[0028] This embodiment provides a method for detecting urban waterlogging, which can be executed by devices such as servers, and through calculation, data output and discrimination of devices such as servers, the detection of waterlogging can be realized, such as figure 1 shown, including the following steps:

[0029] Step S101, obtaining the cloud layer position and rainfall of the cloud layer over the target city.

[0030]Specifically, the target city may refer to any city. When the Bureau of Meteorology reports that heavy rainfall will occur in the target city in the future target time period, if you want to know the overall or local rainfall in the target city in the future target time period, you first need to accurately obtain the cloud cover over the target city Location. The position of the cloud layer in this embodiment may be the position of a cloud that may rain in a certain area or in the local vertical sky directly above the target city. The position of the clo...

Embodiment 2

[0087] This embodiment provides a device for detecting urban waterlogging, which can be used to implement the method for detecting urban waterlogging in Embodiment 1 above. Waterlogging detection, such as figure 2 As shown, the device includes:

[0088] Obtaining module 201, for obtaining the cloud layer position and rainfall of the cloud layer over the target city;

[0089] A prediction module 202, configured to obtain wind condition information of the target city within a future target time period according to the current wind condition forecast of the target city, the wind condition information including the wind conditions of each area of ​​the target city;

[0090] A location module 203, configured to calculate a rainfall location according to the cloud layer location and the wind condition information;

[0091] A coefficient module 204, configured to obtain the runoff coefficient of each building area covered by the rainfall location, wherein the runoff coefficient is...

Abstract

The embodiment of the invention provides an urban waterlogging detection method and device. The method comprises the following steps: acquiring a cloud layer position and rainfall of an overhead cloud layer of a target city; predicting wind condition information of the target city in a future target time period according to the current wind condition of the target city, wherein the wind condition information comprises the wind condition of each region of the target city; calculating a rainfall position according to the cloud layer position and the wind condition information; the runoff coefficient of each building area covered by the rainfall position is obtained, and the runoff coefficient is used for representing the drainage capacity of the corresponding building area; calculating the rainfall capacity of each building area covered by rainfall based on the rainfall capacity and the rainfall position; and determining whether waterlogging will occur in the building area according to the runoff coefficient of each building area and the rainfall of the corresponding building area. By predicting the rainfall capacity and the rainfall position of the cloud layer above the target city in advance, the rainfall capacity of each region in the target city can be accurately predicted, and the waterlogging detection accuracy of each region of the city is improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method and device for detecting urban waterlogging. Background technique [0002] Whenever strong convective weather comes, under the attack of heavy rain, different degrees of waterlogging will occur in various areas of the city. Due to the different topography of each area, it will bring great drainage pressure to the drainage system in some areas of the city. , extremely prone to waterlogging. [0003] At present, in order to solve the problem of waterlogging in the city, the existing technologies mostly monitor the city as a whole, so as to quickly identify the waterlogged area, or predict the water level after the waterlogging, and how to quickly discharge the urban waterlogging method. The most commonly used method of judging waterlogging is more based on the comprehensive analysis of rainfall data over the years and the location of waterlogging all year round to pred...
