Embodiment one
It is a kind of sponge city river water level control method flow diagram provided by the embodiments of the present application referring to Fig. 1.
In the step s 100, river water level value and current outer urban river water place value in current are obtained.
In controlling when the water level value in river and outer river, it is necessary first to perhaps current interior river water level value and outer urban river water
Place value, that is, monitor interior river water level value and outer urban river water place value in real time, pass through internal urban river water place value and outer river water level
The monitoring of value determines the need for draining and displacement is how many, to achieve the purpose that water level control.
In the embodiment of the present application, internal river and outer river are realized by the pressure water-level sensor in interior river and outer river
The monitoring of water level value.Wherein, three pressure water-level sensors are set in interior river, two pressure level sensors is set in outer river
The two sides of interior river intermediate region are arranged in device, the two of them pressure water-level sensor in interior river, another pressure water level passes
Sensor is positioned close to the middle position of sill may；Outer river is arranged in close to sill may in two pressure water-level sensors in outer river
Position.The pressure water-level sensor in interior river and outer river is arranged in same level liquid level.
The numerical value monitored by the pressure water-level sensor in interior river and outer river water level sensor is counted and is calculated current
Interior river water level value and outer urban river water place value.
State in step s 200, judges whether current interior river water level value exceeds the peak of preset water level range.
Since the waters in outer river is broad, the factor for influencing outer river water level is more, and interior river is located in sponge city, water
Position variation is affected to sponge city, therefore, mainly passes through interior river water level value and outer urban river water in the embodiment of the present application
The variation of place value controls interior river water level value, prevents interior river water level height from causing city waterlogging.
Therefore, when getting river water level value and current outer urban river water place value in current, judge river water level in current
Whether value exceeds the peak of preset water level range.The water level value in sponge city inland river road is within the scope of preset water level, ability
The water in river had not only been able to satisfy urban life requirement in guaranteeing, but also can prevent waterlogging from impacting to city.

The peak enclosed, it is determined whether the water in interior river is expelled to outer river, so that river water level is excessively high to sponge city in reducing
Influence.
Embodiment two
The embodiment of the invention provides another sponge city river water level control method flow diagrams.For details, reference can be made to
Step S100 flow diagram as shown in Figure 2.
In step s101, the continuous wave pattern of river water level and the continuous wave pattern of outer river water level in obtaining.
The water level value in river in the pressure water-level sensor real-time monitoring in interior river, meanwhile, the pressure water level in outer river passes
Therefore the water level value in the outer river of sensor real-time monitoring obtains the interior continuous wave pattern of river water level and outer urban river water in cycle time
The continuous wave pattern in position.
As shown in figure 3, fluctuating sequential chart for river water level provided by the embodiments of the present application.Wherein, interior river water level is continuous
The abscissa of wave pattern and the continuous wave pattern of outer river water level indicates the time, and ordinate indicates water level value.When by obtaining the period
Interior river water level value and outer urban river water place value, the water level value that will acquire are connected according to time sequencing, and it is continuous just to obtain water level
Wave pattern.
Interior river water-level fluctuation sequential chart illustrates the variation and variation tendency of water level in interior river；Similarly, outer river
Water-level fluctuation figure illustrates the variation of water level in outer river.From the figure 3, it may be seen that since outer river is affected by stormy waves, water,
The SEA LEVEL VARIATION fluctuation in interior river is less than outer river water level and changes.
The interior river water level value monitored due to current point in time and outer urban river water place value are influenced by many factors, example
Such as, season, stormy waves, water etc., therefore, the interior river water level value of current point in time and outer urban river water place value are for current river
Water level indicates that accuracy rate is low, is not enough to indicate current urban river water place value.So obtaining river water level value and outer urban river water in current
When place value, interior river water-level fluctuation figure and outer river water level wave pattern counting statistics can be passed through.
In step s 102, in fixed interval, interior river water level value and outer urban river water in preset time period are intercepted
Place value.
As shown in figure 3, every the set time, intercepting the interior river water level value in a period of time in fixed interval
With outer urban river water place value.In the embodiment of the present application, can from before current point in time one month or week age in, cut
The urban river water place value in fixed interval in preset time is taken, to offset stormy waves in the short time, water etc. to water level value
It influences.
In step s 103, the average value of interior river water level value and outer urban river water place value in interception preset time period are calculated
Average value.
Preset time period is set as five minutes, and interval time is set as three minutes, then, it was intercepted five minutes every three minutes
Interior river water level value and outer urban river water place value.In the embodiment of the present application, the interior river water level of 10 sections of preset time periods can be intercepted
Value and outer urban river water place value, calculate the average value of river water level value and outer urban river water place value in 10 sections of preset time periods.
In step S104, determine that the average value of interior river water level value is river water level value, outer urban river water in current respectively
The average value of place value is current outer urban river water place value.
Compared with the average value for directly calculating interior river water level value and outer urban river water place value, it can reduce because of stormy waves, season
Influence caused by water-level fluctuation influence, to keep river water level value and current outer urban river water place value in current more accurate,
The water level value in river and outer river in capable of more indicating current.
Accordingly, it can be determined that interior river water level value average value is that river water level value, outer urban river water place value average value are in current
Current outer urban river water place value.
Seen from the above description, by calculating the average value of interior river water level value and outer river in interception preset time period
The average value of road water level value can reduce influence of the factors such as stormy waves, season to water level value, make in current river water level value and current
The numerical value of outer urban river water place value is more accurate, thus river water level in more accurate control.
Embodiment three
It referring to fig. 4, is another step S100 flow diagram provided by the embodiments of the present application.
In step s105, interior river water level value and the outer urban river water place value in preset time period are obtained.
Provided by the embodiments of the present application is another statistics meter about current interior river water level value and outer urban river water place value
Calculation method.In interior river and outer river water level wave pattern, any river interior river Zhi Hewai value intercepted in preset time period,
And the identical period in corresponding wave pattern.For example, in intercepting in river water level value wave pattern and outer urban river water place value wave pattern
The period corresponding water level value of identical season identical month same time.
In step s 106, the maximum value and minimum value of interior river water level value in the preset time period, Yi Jisuo are removed
State the maximum value and minimum value of urban river water place value inside and outside preset time period.
By in the interior river water level value and outer urban river water place value in the preset time period of interception maximum value and minimum value go
It removes, due to stormy waves, the influence in season, the variation of river liquid level is varied widely, and causes pressure water-level sensor collected
Data become larger larger, but collected data can not really reflect urban river water place value at this time, therefore, in the embodiment of the present application
The maximum value and minimum value of river water level value and outer urban river water place value in removing, to exclude extraneous factor to the shadow of river water level
It rings.
In step s 103, calculate removal maximum value and minimum value after interior river water level value average value and with outside road
The average value of water level value.
Several outer urban river water place values of interior river water level value after removing minimum value and maximum value, can effectively reflect in time period
The variation of urban river water place value calculates the average value of interior river water level value and outer urban river water place value at this time, and average value reflects default
Urban river water place value in period.
In step S104, determine that the average value of the interior river water level value is river water level value in current respectively, it is described
The average value of outer urban river water place value is current outer urban river water place value.
Since the river water surface is in continually changing state, the river water level of current point in time acquisition under the influence of stormy waves
There are large errors for value, and therefore, it is necessary to determine current urban river water place value by the way that the urban river water place value in preset time period is comprehensive.This
To apply in embodiment, the interior river water level value average value that above-mentioned steps are calculated is determined as river water level value in current, with
And outer urban river water place value average value is determined as current outer urban river water place value.
Seen from the above description, in the embodiment of the present application, by the interior river water level value and outer urban river water in preset time period
The maximum value and minimum value of place value remove, that is, by SEA LEVEL VARIATION caused by improper factor to removing, to make inland river
Road water level value and outer urban river water place value are accurately calculated, and then keep interior river water level control more accurate.

Road.
If difference is greater than zero, interior river water level value is greater than outer urban river water place value at this time, needs to control and open a sluice gate interior river
Water be expelled to outer river.That is at this point, interior river water level value is higher than the peak of preset water level range, while interior river
Water level value is higher than outer urban river water place value, therefore, it is necessary to which the water in interior river is expelled to outer river, at this point, can pass through interior river
Liquid level between outer river is poor, and the water in interior river is expelled to outer river using interior river water gravity.
In step S303, if the difference less than zero, controls draining pump group pumping water to outer river.
If difference less than zero, illustrates that the water level in river at this time is more than preset water level range peak, meanwhile, outer river
Water level value is also higher than interior river water level value, the water in interior river can not be expelled to outer river by interior river height of water level difference at this time
Road, therefore, it is necessary to control the draining pump group being arranged between inside and outside river interior urban river water is expelled in outer river.
When using pump group pumping water is drained, the number for opening draining pump can be determined according to the difference of inside and outside urban river water place value,
If difference is bigger, the quantity for opening draining pump is more, more can guarantee interior river water level value by draining control in preset water level
