Embodiment 1

[0038] see figure 1 , is a schematic flow chart of a method for controlling the water level of a sponge city river provided by an embodiment of the present application.

[0039] In step S100, the current water level value of the inner channel and the current water level value of the outer channel are acquired.

[0040] When controlling the water level values ​​of the inner and outer rivers, the current water level of the inner and outer rivers is needed first, that is, real-time monitoring of the water level of the inner and outer rivers. The monitoring of the value determines whether drainage is required, and how much drainage is required, so as to achieve the purpose of water level control.

[0041] In the embodiment of the present application, the monitoring of the water level values ​​of the inner and outer rivers is realized through the pressure water level sensors of the inner and outer rivers. Among them, three pressure water level sensors are set in the inner channel...

Embodiment 2

[0052] The embodiment of the present invention provides a schematic flowchart of another method for controlling the water level of a sponge city river. For details, please refer to figure 2 A schematic flow chart of step S100 is shown.

[0053] In step S101, the continuous fluctuation map of the water level of the inner channel and the continuous fluctuation map of the water level of the outer channel are obtained.

[0054] The pressure water level sensor of the inner channel monitors the water level value of the inner channel in real time, and at the same time, the pressure water level sensor of the outer channel monitors the water level value of the outer channel in real time. Therefore, the continuous fluctuation diagram of the water level of the inner channel and the continuous fluctuation diagram of the water level of the outer channel are obtained within the cycle time.

[0055] Such as image 3 Shown is the continuous diagram of the river water level fluctuation provid...

Embodiment 3

[0067] see Figure 4 , is a schematic flowchart of another step S100 provided in the embodiment of the present application.

[0068] In step S105, the water level value of the inner channel and the water level value of the outer channel within a preset time period are obtained.

[0069] The embodiment of the present application provides another statistical calculation method about the current water level value of the inner channel and the water level value of the outer channel. In the water level fluctuation diagram of the inner channel and the outer channel, the values ​​of the inner channel and the outer channel within the preset time period are arbitrarily intercepted, and correspond to the same time period in the fluctuation diagram. For example, intercept the water level values ​​corresponding to the time periods in the same season, the same month, and the same time period in the fluctuation diagram of the water level value of the inner channel and the fluctuation diagra...

Abstract

The invention belongs to the field of river drainage technologies and provides a sponge city river channel water level control method. The method includes the following steps that: a current inner river channel water level value and a current outer river channel water level value are obtained; whether the current inner river channel level value exceeds the highest value of a preset water level range is judged; and if the current inner river channel water level value exceeds the highest value of the preset water level range, water in an inner river channel is discharged to an outer river channel until the inner river channel water level value reaches the lowest value of the preset water level range. With the method of the present invention adopted, the water level in the river channel can be effectively controlled, and the water level in the river channel can be prevented from being too high to affect a city.

Description

technical field [0001] The invention belongs to the technical field of sponge city drainage, and in particular relates to a method for controlling the water level of a sponge city river. Background technique [0002] Sponge city takes advantage of its characteristics of water storage and water absorption, and discharges the accumulated water in the city to the outer channel through the method of river drainage. Considering the impact of the water level of the inner city on the city, it is necessary to control the water level of the inner river within an appropriate range to prevent the water level from being too high during the flood season and unable to be discharged in time, and to prevent the water level from being too low to cause water shortage in the city during the dry season. [0003] Therefore, water level control in the sponge city has become an urgent problem to be solved. Contents of the invention [0004] An embodiment of the present invention provides a meth...
