In this embodiment, according to rainfall data corresponding to the target rainfall orders of the plurality of statistical stations in the target area, the design rainfall of the target area is obtained by means of average calculation, that is, the control parameter value of the target area is obtained by means of calculation.
As an optional embodiment of the present invention, the step S32 is as follows: according to the target control times, the rainfall orders of all the statistical stations and the rainfall data corresponding to the rainfall orders of all the statistical stations, determining the rainfall data corresponding to the target rainfall orders of all the statistical stations comprises the following steps:
determining statistics years according to historical data of a preset time period; and determining rainfall data corresponding to the target rainfall orders of the statistical sites according to the statistical annual times, the target control times and the rainfall orders of the statistical sites and the rainfall data corresponding to the rainfall orders.
In this embodiment, according to the historical data of the preset time period, the statistical annual time is determined, for example, when the preset time period is 5 years, the statistical annual time is 5; dividing rainfall data counted by each statistic site according to the annual number, and respectively determining rainfall data corresponding to the target rainfall occasions of each year of each statistic site, for example, the rainfall data corresponding to the target rainfall occasions of each year of the A rainfall site are A1, A2, A3, A4 and A5; then the rainfall data corresponding to the target rainfall pattern of each statistical site can be determined by the following formula:
Ai＝(A1+A2+A3+A4+A5)/5，
wherein Ai is rainfall data corresponding to the target rainfall pattern of the rainfall station A;
specifically, A, B, C, D, E, F, G rainfall stations may exist in the target area, and the control parameter value of the target area, that is, the design rainfall P, may be calculated according to the following formula:
P＝(Ai+Bi+Ci+Di+Ei+Fi+Gi)/7，

and determining the scale of the target engineering according to the control parameter value of the target area. In this embodiment, the control parameter value of the target area may be a design rainfall of the target area, and the scale of the target project may be the capacity of the combined overflow regulation reservoir.
Specifically, the capacity of the combined overflow regulation reservoir may be determined according to the designed rainfall of the target area and the area of the target area; the historical data can be used as training samples, the training samples are input into the design rainfall information, and the output information is the capacity of the combined overflow regulation pool; the history data includes capacity information, rainfall data, city area information, and the like of the in-city combined overflow regulation pool of the same level as the target area. Training the initial neural network model according to the historical data to generate a capacity analysis model of the combined overflow regulation reservoir, and in the embodiment, inputting the calculated design rainfall of the target area into the capacity analysis model of the combined overflow regulation reservoir to obtain capacity information of the combined overflow regulation reservoir, and guiding actual engineering construction according to the capacity information of the combined overflow regulation reservoir.
The following describes a method for calculating a flow control parameter of a converging channel in detail with reference to an embodiment, and in particular, a method for determining a scale of a converging overflow regulation pool (CSOs) may be based on a long-time sequence and high-resolution numerical simulation result, and may be applied to a specific application scenario of determining a scale of a CSOs regulation pool of an urban drainage system. This city typically has the following conditions: the combined drainage system has long time sequence rainfall data and complete pipe network data. CSOs pollution can be controlled by constructing a CSOs regulation reservoir.
Specifically, rainfall data of a study area (a certain study area in a city) for not less than 5 years and statistical intervals of not more than 5 minutes can be collected, and rainfall sites need to cover the whole study area; and determining the overflow control times N according to the planning target, and determining rainfall field division standards according to the post-rain processing time T in the planning target. And the post-rain treatment time T indicates that the combined sewage collected after rain is required to be treated within T hours, and the corresponding rainfall field division standard is that the accumulated rainfall within T hours is not more than 2mm.
Specifically, the number of times of rainfall of each rainfall statistics site is counted year by year, the rainfall values Pi which are sequenced into N+1 in each rainfall statistics site are extracted according to the number from big to small, the rainfall values of each rainfall site in five years are determined from the time average aspect, and then the design rainfall of a research area is determined.
Specifically, the research city may be a certain river basin in the central city of Beijing city, and the preset planning target may be a planning target in a combined overflow pollution control scheme determined by a functional department in the river basin. 7 rainfall monitoring stations are arranged in a certain river basin, the whole study area is covered by 123 square kilometers, rainfall data last from 2008 to 2017, the duration is 10 years, and the statistical interval of the rainfall data is 5 minutes; according to the objective of the study area flow overflow pollution control planning, the control times of CSOs in the study area are no more than 4 times in each year. And collecting overflow sewage by constructing a combined system regulating and accumulating tank, and conveying the overflow sewage to a downstream sewage plant or a self-built sewage treatment facility for treatment within 24 hours after rain. The precipitation classification criterion was thus determined to be 24h. I.e. the cumulative amount of rainfall within 24 hours does not exceed 2mm. No runoff is generated below 2mm, and effective rainfall is not calculated.
Dividing rainfall orders for each site monitoring data year by year according to rainfall order dividing standards, and extracting and sequencing a fifth rainfall value according to the number from large to small of the rainfall. The fifth rainfall value of each year of each station is shown in table 2 below:
the "/" in the above table indicates that no calculation was included due to the partial absence of the original monitoring data.
Specifically, the fifth spot rainfall value of each ordering of each station is averaged on a time scale, and then the average value of each station is averaged spatially, namely, the final design rainfall is 36.32mm.
