The first growth information of the greenspace is 85 points, and according to the preset correspondence, it may be determined that the adjustment values corresponding to the first growth information are −0.10 tons, −0.15 tons, and −0.20 tons. Based on the irrigation water amount of the greenspace in the next three days being 1.90 tons, 1.85 tons, and 1.80 tons respectively, the irrigation water amount is distributed according to the irrigation rules of the greenspace to determine the plurality of candidate irrigation parameters of the greenspace. In some embodiments, the plurality of candidate irrigation parameters of each greenspace may be combined to determine multiple candidate irrigation schemes.
As another example, the urban management platform may determine, based on the historical data, the historical irrigation scheme corresponding to the time period in which the each greenspace is similar to the preset total amount of irrigation and the first growth information corresponding to each greenspace, and take the aforementioned historical irrigation scheme as a candidate irrigation scheme.
Step 820, the urban management platform performs at least one round of iterative updation on the plurality of candidate irrigation schemes through the preset algorithm until satisfying the preset conditions, the plurality of candidate irrigation schemes after iteratively updating converge to the target irrigation scheme, and the target irrigation scheme includes a set of target irrigation parameters for irrigating the each greenspace within the first future time period.
In some embodiments, the urban management platform may perform the at least one round of iterative updation on the each candidate irrigation scheme through the preset algorithm. For each iteratively updated candidate irrigation scheme, the growth promotion value corresponding to the iteratively updated candidate irrigation scheme is determined based on the iteratively updated candidate irrigation scheme. The growth promotion value may represent overall growth information of all greenspaces within the second future time period. The growth promotion value may be determined based on the second growth information, representing the sum of the second growth scores. The second growth information may represent the growth information of the greenspace within the second future time period. Similar to the historical growth information, the second growth information may be represented through the second growth score. For example, the second growth score may be a value of 0-100. In some embodiments, the iteratively updated candidate irrigation scheme may be processed based on the growth condition prediction model to determine the growth promotion value corresponding to the iteratively updated candidate irrigation scheme. More descriptions regarding the determining the growth promotion value corresponding to the iteratively updated candidate irrigation scheme may be found in
For each candidate irrigation scheme, during a process of iteratively updating the candidate irrigation scheme, the candidate irrigation parameters of the candidate irrigation scheme may correspond to a multi-dimensional increment. The multi-dimensional increment may refer to an adjustment range of the irrigation water amount of each greenspace included in the candidate irrigation scheme in each iteration.
In the first round of iteration, the initial candidate irrigation scheme may be updated based on an initial multi-dimensional increment to obtain the updated candidate irrigation scheme. The updated candidate irrigation scheme is determined as the candidate irrigation scheme to be processed, and the initial multi-dimensional increment is determined as a multi-dimensional increment to be processed in the next round. The initial multi-dimensional increment may be a system default value, experience value, artificial preset value, etc., or any combination thereof, which is set according to actual requirements.
In some embodiments, the initial candidate irrigation scheme may be obtained by initializing vectors. An exemplary process for initializing vectors is as follows: for several greenspaces (assuming the number of greenspaces is D), the number of initial candidate irrigation schemes may be set as N, meanwhile, the dimension of the each initial candidate irrigation scheme is D (each dimension corresponds to the irrigation water amount of a greenspace), a vector Xi0 corresponding to the ith initial candidate irrigation scheme may be denoted as:
(Xi10, Xi20, . . . , XiD0),
the vector corresponding to the N initial candidate irrigation schemes may be denoted as:
((X110, X120, . . . , X1D0), (X210, X220, . . . , X2D0), . . . , (XN10, XN20, . . . , XND0)),
where 0 is the identifier (representing the 0th round of iteration, i.e., an initial value that has not yet started the iteration), i is the number of the candidate irrigation scheme, i≤N.
In each subsequent round of iteration, the multi-dimensional increment to be processed of the round is updated to obtain the updated multi-dimensional increment. The candidate irrigation scheme to be processed is updated based on the updated multi-dimensional increment to obtain the updated candidate irrigation scheme. The obtained candidate irrigation scheme after the update is determined as the candidate irrigation scheme to be processed in the next round, and the updated multi-dimensional increment is determined as the multi-dimensional increment to be processed in the next round.
In some embodiments, updating the multi-dimensional increment to be processed may be realized by updating an increment element to be processed. The increment element is an element of each dimension of the multi-dimensional increment, and the multi-dimensional increment may include a plurality of increment elements. There may be a correspondence between each greenspace and each increment element in the candidate irrigation scheme to be processed. The increment element may be used to represent the adjustment range of the irrigation water amount for the corresponding greenspace.
In some embodiments, the increment element to be processed may be updated based on current loss in the previous round, and the updated increment element is used as the increment element to be processed of the next round. The current loss in the previous round may be determined based on a difference between the candidate irrigation water amount elements obtained in the previous round and the historical optimal candidate irrigation parameters.
Exemplarily, after the k+1 round of iteration, the updated increment element may be calculated through the following formula (1):
v
id
k+1
=ωv
id
k
+c

r
1((pid,pbestk−Xidk+1)+c2r2(pd,gbestk−Xidk) (1),
where i denotes the number of the candidate irrigation scheme, i≤N, d denotes the number of the greenspace, d≤D. k denotes the number of iteration rounds, k≥0. vidk denotes the increment element to be processed after the kth iteration of the ith candidate irrigation scheme. Xidk denotes the ith candidate irrigation scheme obtained after the kth iteration. ω denotes the inertia weight constant. c1 denotes an individual learning factor, c2 denotes a group learning factor. r1 and r2 are arbitrary values within the interval [0,1] to increase the randomness of the search. After the kth round of iteration, pid,pbestk is a value of the optimal solution of the ith candidate irrigation scheme during the previous iterations in the dth greenspace. The optimal solution at this time may refer to after the kth round of iteration, when the growth promotion value of a candidate irrigation scheme is the maximum value among the plurality of growth promotion values corresponding to the previous iterations, the irrigation water amount collection of the each greenspace corresponding to the candidate irrigation scheme (i.e., an individual historical optimal solution). pd,gbestk is a value of the optimal solution of all N candidate irrigation schemes in the dth greenspace after the kth round of iteration. The optimal solution at this time may refer to after the kth round of iteration, among the aforementioned plurality of candidate irrigation schemes with the greatest growth promotion value in the previous iterations, the irrigation water amount collection (i.e., the group historical optimal solution) of the each greenspace corresponding to the candidate irrigation scheme with the largest growth promotion value.
The inertia weight constant ω, the individual learning factor c1, the group learning factor c2, and the arbitrary values r1 and r2 may be system default value, experience values, artificial preset values, etc., or any combination thereof, which are set according to actual requirements.
In some embodiments, the maximum absolute value of the increment element in each iteration may be vmax, i.e., denoting the maximum adjustment range of irrigation water amount for each greenspace. In the k+1 round of iteration, the multi-dimensional increment Vi formed by the adjustment range of irrigation water amount for the each greenspace may be expressed as (vi1, vi2, . . . , viD). The vectors of multi-dimensional increments corresponding to N candidate irrigation schemes may be denoted as ((v11, v12, . . . , v1D), (v21, v22, . . . , v2D), . . . , (vN1, vN2, . . . , vND)). The value of any increment element in the vector may be negative, but the absolute value is not greater than vmax.
In some embodiments, each candidate irrigation scheme to be processed may be updated based on increment element in the updated multi-dimensional increment. Exemplarily, after the k+1 round of iteration, the updated candidate irrigation scheme may be calculated through the following formula (2):
X
id
k+1
=X

For example, after the first round of iteration, the updated ith candidate irrigation scheme may be calculated through the following formula (3):
X
i
1=(Xi11, Xi21, . . . , XiD1)=(Xi10, vi11, Xi20+vi21, . . . , XiD0+viD1) (3),
the vector representation corresponding to the N updated candidate irrigation schemes may be calculated through the following formula (4):
(X11, X21, . . . , XN1)=((X111, X121, . . . , X1D1), (X211, X221, . . . , X2D1), . . . , (XN11, XN21, . . . , XND1))=((X110+v111, X120+v121, . . . , X1D0+v1D1), (X210+v211, X220+v221, . . . , X2D0+v2D1), . . . , (XN10+vN11, Xi20+vN21, . . . , XND0+vND1)) (4).
In some embodiments, in each round of iterative updation of the candidate irrigation scheme, the total irrigation water amount Q of all greenspaces (i.e., the sum of the vector values of all dimensions) may have restriction:
Q=Σ(Xid)=(Xi1+Xi2+Xi3, . . . , +XiD)≤S,
where S denotes the preset total amount of the irrigation.
In some embodiments, if after an iteration, the value of the total irrigation water amount Q corresponding to the candidate irrigation parameters in the candidate irrigation scheme is greater than S, the irrigation water amount of the each greenspace in the candidate irrigation scheme may be reduced according to a ratio (S/Q). For example, after the fourth iteration, the total irrigation water amount corresponding to the ninth candidate irrigation scheme X94=(X914, X924, . . . , X9D4) is:

and the X94 is reduced to:

In some embodiments, the candidate irrigation scheme may be iteratively updated through the above preset algorithms until satisfying the preset conditions, and the iterative updation ends. The preset condition may be that the preset value is reached, or the ratio of the growth promotion value obtained by algorithms to the preset theoretical maximum growth promotion value is greater than the threshold.
The plurality of candidate irrigation schemes after iteratively updating converge to a target irrigation scheme. The target irrigation scheme includes a set of target irrigation parameters for irrigating the each greenspace within the first future time period. At this time, the growth promotion value corresponding to the target irrigation scheme should be the maximum value of the growth promotion values corresponding to the plurality of candidate irrigation schemes updated in previous iterative updations.
Some embodiments of the present specification may continuously update the plurality of candidate irrigation schemes through a way of iteration, and continuously optimize the candidate irrigation schemes. In this way, the target irrigation scheme with the greatest growth promotion value is determined, and the greenspace can further achieve the best growth condition while saving irrigation water.
Step 910, the urban management platform obtains the preset total amount of irrigation in the target area within the first future time period.
Step 920, the urban management platform determines the plurality of candidate irrigation schemes of the plurality of greenspaces based on the preset total amount of irrigation and the first growth information corresponding to each greenspace, and each candidate irrigation scheme includes a set of candidate irrigation parameters for irrigation of each green land.
Step 930, the urban management platform determines the target environment information of the each greenspace within the second future time period.
The target environment information may refer to the environment information within the second future time period. Similar to the historical environment information, the target environment information may include a rainfall, air temperature, humidity, light intensity, wind power, etc. of the area where the greenspace is located within the second future time period. The urban management platform may obtain the target environment information through the sensor network platform.
Step 940, for the each candidate irrigation scheme, after irrigating the plurality of greenspaces based on the candidate irrigation scheme, the urban management platform determines the second growth information of the each greenspace within the second future time period through the growth condition prediction model based on the candidate irrigation scheme, the target environment information, and the first growth information.
For the each candidate irrigation scheme, the irrigation parameters, target environment information, and first growth information corresponding to the candidate irrigation scheme of a greenspace may be input into the growth condition prediction model, and the output of the growth condition prediction model may be the second growth information of the greenspace.
Step 950, the urban management platform determines the growth promotion value corresponding to the candidate irrigation scheme based on the second growth information of each greenspace.
Step 960, the urban management platform determines the target irrigation scheme of the plurality of greenspaces based on the growth promotion value corresponding to the each candidate irrigation scheme.
The urban management platform may determine the candidate irrigation scheme corresponding to a maximum growth promotion value as the target irrigation scheme.
In some embodiments of the present disclosure, the growth condition prediction model is configured to compare the plurality of candidate irrigation schemes, determine a candidate irrigation scheme with more growth promotion value as the target irrigation scheme from the plurality of candidate irrigation schemes by considering from a next future time period in a longer-term. Under the condition of ensuring the normal growth of the greenspace, more scientific target irrigation parameters may be determined to avoid waste of resources.
