Embodiment 1

[0057] Such as Figure 1A As shown, it is a schematic flow chart of the method for detecting the time of water accumulation at the water accumulation point described in this embodiment. The method described in this embodiment solves the problem that the existing technology cannot detect the surrounding information of the water accumulation point and automatically obtain the accumulation of water after analysis. A technical problem with the time of retreating water. The method for detecting the receding time of the accumulated water point described in the present embodiment comprises the following steps:

[0058] Step 101, for the area where water accumulation occurs (that is, the water accumulation point area), obtain the information of the water accumulation point, and report to the system that detects the water accumulation time of the water accumulation point.

[0059] Wherein, the information of the water accumulation point includes: the area of ​​the water accumulation po...

Embodiment 2

[0075] Such as Figure 2A As shown, it is a schematic flow chart of the method for detecting the time of water accumulation at the water accumulation point described in this embodiment. On the basis of Embodiment 1, this embodiment describes the acquisition of the total amount of water accumulation and drainage flow, and calculates the water accumulation point. The specific content of the retreat time of the water point. The method described in this embodiment includes the following steps:

[0076] Step 201, receiving the location of the water accumulation point in the water accumulation point area, the total amount of water accumulation and the area of ​​the accumulation water of the water accumulation point.

[0077] Step 202, according to the location of the water accumulation point and using geographic information system calculations to obtain the pipe point information data of the pipe points around the water accumulation point, and perform the pipe point connectivity an...

Embodiment 3

[0089] Such as image 3 As shown, it is a schematic structural diagram of the system for detecting the water receding time of the water accumulation point in this implementation. The system described in this embodiment is used to implement the method for detecting the receding time of water accumulation points described in the above embodiments. The system described in this embodiment includes: a receiving device 801 , a device 802 for obtaining information on water accumulation points, a device 803 for detecting the flow rate of pipelines, a device 804 for obtaining drainage flow rate, and a device 805 for calculating water receding time.

[0090]Wherein, the receiving means 801 is connected with the water accumulation point information acquisition means 802, and is used for receiving the position of the accumulation point at the accumulation point, the total amount of accumulated water and the accumulation area of ​​the accumulation point.

[0091] The water accumulation po...

Abstract

The invention discloses a method for detecting the receding time of a water accumulation point, which includes: receiving the position of the water accumulation point in the area of ​​the water accumulation point, the total amount of water accumulation and the area of ​​the accumulation of water at the water accumulation point; The geographical information system calculates and obtains the pipe point information data of the pipe points around the water accumulation point, and analyzes the pipe point connectivity according to the pipe point information data to obtain the upstream and downstream pipes of the pipe point; the pipe point is detected by the rainwater flow meter installed in the pipe well The flow rate in the upstream and downstream pipelines; the rain gauge is used to monitor the rainfall intensity of the water accumulation point, and the rainfall flow at the water accumulation point is obtained by combining the water accumulation area; The drainage flow of the water accumulation point is obtained from the flow rate, the flow rate in the downstream pipeline and the rainfall flow; the water withdrawal time of the water accumulation point is calculated according to the total amount of water accumulation and the drainage flow. The disadvantage of not being able to know the time of stagnant water receding before has been changed.

Description

technical field [0001] The invention relates to the technical field of detecting water accumulation at a water accumulation point, and more particularly, relates to a method and system for detecting water receding time at a water accumulation point. Background technique [0002] At present, my country's urbanization is developing rapidly, and among the many effects that follow, many factors have exacerbated the situation of urban waterlogging during the flood season. Urban waterlogging refers to the phenomenon of accumulated water disasters in cities due to heavy or continuous precipitation exceeding the urban drainage capacity. After the city enters the flood season, waterlogging is prone to occur in low-lying areas, especially at the position of the underpass bridge, which will pose a serious threat to the safety of people's lives and properties. [0003] After urban flooding occurs, if it is possible to predict when the water at each water accumulation point will subside...
