[0003] Flood refers to the rapid increase of water volume in rivers and lakes caused by natural factors such as heavy rain, rapid melting of ice and snow. It is a natural disaster phenomenon. Flood disasters involve a wide range of disciplines, including meteorology, geography and other disciplines. The problem is extremely complicated. Therefore, it is necessary to prevent flood disasters so that human beings can take preventive measures in time; there are many existing technical solutions to predict flood disasters, which will identify the characteristics of floods through neural networks, vector machines, and gray prediction models and use them to predict floods. Predict the situation; although the above scheme can predict the flood, there is no technical scheme for the degree of impact on the designated area in the event of a flood, so that people in the area can prevent the flood in time;

Embodiment 1
[0114] Example 1: Obtain the real-time location information of the designated area and the flood flow, specifically S=(x, y)=(150000, 254000) and Q=(e 2 ,r 2 )=(80000,150000), if detected
[0115]
[0116] According to the formula:
[0117] According to the above settlement, P(G|L0)=0.83, P(L>0)=0.75;
[0118] The probability that the flood flows through the specified area when L<0 is:
[0119]
[0120] Among them: P(G|L0) refers to the probability that the distance between the specified area and the real-time flow position of the flood is greater than 0, and P(G|L>0) refers to the distance between the specified area and the real-time flow position of the flood is greater than 0. The probability of receiving the specified area under the conditions, P(L<0|G) refers to the probability that the distance between the specified area and the real-time flow position of the flood under the specified area is less than 0, and L refers to the specified area and the real-time posi...
Embodiment 2
[0122] Embodiment 2: Acquire the real-time location information of the designated area and the flood flow, specifically S=(x, y)=(145260, 110000) and Q=(e 2 ,r 2 )=(145260,1100000), if detected
[0123]
[0124] According to the formula:
[0125] According to the above settlement, P(G|L0)=0.12, P(L>0)=0.11;
[0126] The probability that the flood flows through the specified area when L<0 is:
[0127]
[0128] Among them: P(G|L0) refers to the probability that the distance between the specified area and the real-time flow position of the flood is greater than 0, and P(G|L>0) refers to the distance between the specified area and the real-time flow position of the flood is greater than 0. The probability of receiving the specified area under the conditions, P(L<0|G) refers to the probability that the distance between the specified area and the real-time flow position of the flood under the specified area is less than 0, and L refers to the specified area and the real-tim...

Abstract
The invention discloses a smart water comprehensive information management system based on big data. The system includes a flood data analysis module, a flood impact analysis module, a material dispatch management module and a water management platform; the flood data analysis module is used to obtain the precipitation in the area. information, according to the precipitation information to analyze the probability of floods in the area; the flood impact analysis module is used to analyze the degree of impact of floods on the designated area; so as to determine the probability of floods in the designated area, if the degree of impact is high, notify the designated area in time Flood control measures are taken; the material dispatch management module is used for dispatching and distributing materials to the designated area according to the impact of floods on the designated area; thus, material distribution can be performed in the designated area; the water management platform is used for saving data and publishing Instructions; through the flood impact analysis module, the impact of floods on the area can be prevented in time.
Description
technical field [0001] The invention relates to the technical field of big data, in particular to a smart water affairs comprehensive information management system based on big data. Background technique [0002] Nowadays, flood disasters occur more and more frequently in the world. Once a flood disaster occurs, it will greatly affect the economic loss of the people and the loss of national property; [0003] Flood refers to the rapid increase of water volume in rivers and lakes caused by natural factors such as heavy rain and sharp melting of ice and snow. It is a natural disaster phenomenon. Flood disasters involve a wide range of disciplines, including meteorology, geography and other disciplines. Therefore, it is necessary to prevent flood disasters so that humans can take preventive measures in time; there are many technical solutions to predict flood disasters, and the characteristics of floods will be identified through neural networks, vector machines, and gray predi...
