Urban waterlogging process-oriented visualization method

Abstract

The invention discloses an urban waterlogging process-oriented visualization method, which comprises a water volume monitoring module, an information display module and a disaster situation processing module, and comprises the following steps: S1, the water volume monitoring module comprises a water level detection unit, a GPS positioning unit, a video monitoring unit and an image transmission unit; the output end of the water volume monitoring module is connected with an information display module, and the water volume monitoring module is used for detecting the water level height of the accumulated water volume; S2, the information display module comprises an information receiving unit, an imaging processing unit and a disaster situation alarm unit, the output end of the information display module is connected with a disaster situation processing module, and the information display module is used for imaging and displaying the ponding situation. The process is simple, image display and sound alarm are carried out on water accumulation points in real time, the disaster situation is more visual, rescue and relief work are more timely, life and property safety of citizens is guaranteed, rescue work efficiency is improved, and the method is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of urban waterlogging detection, in particular to a visualization method for urban waterlogging process. Background technique [0002] Urban waterlogging refers to the phenomenon of accumulated water disasters in cities due to heavy or continuous precipitation exceeding the urban drainage capacity. The objective cause of waterlogging is the high intensity and concentrated range of rainfall. Where the rainfall is particularly rapid, waterlogging may form, and the rainfall intensity is relatively strong and the time is relatively long. Waterlogging may also form. Urban waterlogging is relatively common in China. Judging from the areas where it occurs, it mainly occurred in some coastal areas with relatively low terrain in the past, and it often occurred in inland cities. In the past, the area of ​​urban construction land was small, and the area to choose from was relatively large. Generally, areas with relat...

AI Technical Summary

Problems solved by technology

In the past, the area of ​​urban construction land was small, and the area to choose from was relatively large. Generally, areas with relatively high terrain were selected for construction. However, now the urban land is very tight and there is little room for choice. Therefore, the problem of urban waterlogging is obvious. Due to the vegetation in the city Sparse, fewer ponds, unable to store rainwater, leading to the phenomenon of water catchment to form waterlogging; and the emergence of the heat island effect, resulting in an increase in the probability of rainstorms, concentrated precipitation, and thus the formation of waterlogging

[0003] A small number of large and medium-sized cities in my country have begun to plan or are carrying out the construction of monitoring, forecasting and early warning systems for urban rainstorms and waterlogging. Technical support to reduce the impact of waterlogging on the lives of urban residents. However, most of the existing detection systems are displayed through data. The data display method is not intuitive, and the disaster-affected point cannot be judged immediately. It needs to be calculated and converted, and the disaster-affected situation cannot be displayed intuitively immediately. As a result, emergency rescue and disaster relief cannot be carried out in time, and the property and lives of citizens are threatened. Therefore, we propose a visualization method for the process of urban waterlogging
