Technical Field

[0001] The invention relates to the technical field of early warning devices, and in particular to an early warning device for predicting water level and water quality in a river network. Background Art

[0002] A network is a complex linear structure pattern composed of nodes and edges. Within a certain area, each path is closed to each other to form a connected closed loop. The water level refers to the elevation of the free water surface relative to a certain base surface, and the distance between the water surface and the river bottom is called the water depth. The base surface used to calculate the water level can be a characteristic sea level elevation at a certain place as the zero-point leveling base surface, called the absolute base surface, and the Yellow Sea base surface is commonly used; or the elevation of a specific point can be used as a reference to calculate the zero point of the water level, called the station base surface. The water level is the most intuitive factor reflecting the water conditions of the water body, and its changes are mainly caused by the increase or decrease of the water volume of the water body. The water level process line is a curve of the change of the water level at a certain place over time, with the horizontal coordinate being time and the vertical coordinate being the water level. Now, river network water level and water quality monitoring devices are generally used to monitor water quality and water level, and the river network water level and water quality prediction and early warning are realized through monitoring data.
