Urban drainage early warning system based on GIS

Abstract

The invention provides an urban drainage early warning system based on a GIS. The urban drainage early warning system comprises a data acquisition module, a data calculation module and a result display module. The data acquisition module is used for acquiring the maximum flow of a drainage branch pipe in unit time and acquiring flow data of a catch basin directly communicated with the drainage branch pipe; the data calculation module is used for predicting the flow of the catch basin in the next time period T according to the flow data, and obtaining the flow of the catch basin at each moment in the time period T; whether the drainage branch pipe can meet the drainage requirement or not is judged according to the flow; and the result display module is used for displaying the judgment result in a GIS model of the urban drainage pipeline and sending an alarm prompt to a worker when the judgment result is that the drainage branch pipe cannot meet the drainage requirement. According to the system, the waterlogging condition is early warned and prompted in advance, and the waterlogging occurrence probability can be effectively reduced.

Description

technical field [0001] The invention relates to the early warning field, in particular to a GIS-based urban drainage early warning system. Background technique [0002] Due to inadequate planning during construction, the drainage systems of many cities cannot well meet the demand for drainage in the rainy season, which is likely to cause urban waterlogging. In the prior art, it is generally to wait for waterlogging to occur before performing corresponding drainage treatment on the area where waterlogging occurs, such as using a water pump to speed up drainage. Obviously, waiting for waterlogging before processing will greatly affect the normal operation of the city. Therefore, we need early warning of urban drainage so that municipal staff can take corresponding measures in advance. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a GIS-based urban drainage early warning system, which includes a data acqu...
