Background
Along with the development of the industrial and urbanization process, the urban pipe network coverage rate is larger and larger, the pipe network converging process is more and more complex, the distributed hydrological model and the pipe network model are commonly used for simulating urban waterlogging and urban water environment, how to reasonably carry out converging operation directly influences the simulation result and the model efficiency of water quantity and water quality. The conventional hydrological model is mainly based on digital elevation information to divide sub-watersheds and codes the sub-watersheds step by step according to the sequence from upstream to downstream, so that when river convergence calculation is performed, calculation is performed according to the number of the sub-watersheds from small to large, and the upstream sub-watersheds can be guaranteed to finish convergence calculation when the downstream sub-watersheds perform convergence calculation.
However, because the urban pipe network is complex in distribution, the sub-basin codes of the sewage path of the pipe network are not arranged from small to large, so that the pipe network convergence and the slope river convergence cannot be calculated simultaneously, or repeated calculation exists, and the risk of result error is caused. Therefore, whether the coding of pipe network convergence on the related sub-basin reasonably and directly influences the calculation efficiency and result of the water quantity and the water quality of the basin.

Detailed Description
The invention is described in detail below with reference to the figures and specific examples.
As shown in fig. 1, the method for calculating the sub-basin confluence algorithm sequence based on the topological relation of the sewage pipe network provided by the invention comprises the following steps:
step S10, the sub-domains are divided according to the natural water system and encoded so that each sub-domain has a unique code.
In step S10, the coding scheme of the sub-stream field is continuously increased from 1, and there is no repetition coding between the sub-stream fields. As shown in fig. 2, the whole example basin is divided into 14 sub-basins according to the natural water system, and each sub-basin is assigned with a unique number (numbers 1 to 14 in fig. 2), and it should be noted here that when the sub-basins are coded, each sub-basin code is not repeated, no matter how the sub-basin codes are carried out, different sub-basin coding systems are obtained, and the subsequent calculation of the method of the present invention is not affected.
And S20, constructing an upstream and downstream confluence topological relation table of the sub-basin where the natural water system is located according to the natural water system confluence path and the sub-basin codes, and obtaining the number information of the direct upstream sub-basin of each sub-basin relative to the natural water system.
In step S20, first, according to the topological relation of the natural water converging path (dashed line in fig. 2), the upstream topological relation information of each sub-basin with respect to the natural water system is obtained, as shown in table 1 (corresponding to fig. 2), where an upstream "m" code indicates an upstream sub-basin code merging into the current sub-basin in the natural water system, m indicates the several upstream sub-basins of the current sub-basin, a sub-basin code of "0" indicates that there is no upstream sub-basin, and a value greater than "0" indicates an encoding value of the upstream sub-basin corresponding to the sub-basin; the number of the upstream sub-stream domains is equal to the number of all upstream m coding values which are not 0 and are used for statistical calculation without influencing the calculation sequence.
And step S30, constructing an upstream and downstream confluence topological relation table of the sub-basin where the sewage pipe network is located according to the sewage pipe network confluence path and the sub-basin number, and obtaining the number information of the direct upstream sub-basin of each sub-basin relative to the sewage pipe network.
In step S30, first, according to the topological relationship of the sewage pipe network (the thick solid line in fig. 2) in the drainage basin, the upstream topological relationship information of the sewage pipe network relative to each sub-drainage basin is obtained, as shown in table 1, it should be noted that in the embodiment shown in table 1, the sewage pipe network system has only 2 upstream at most, and the natural water system has 3 upstream at most, which is related to a specific drainage basin, and the maximum number of upstream does not affect the subsequent calculation.
Table 1: and a topological relation table of upstream and downstream confluence of the sub-basin where the natural water system and the sewage pipe network are located.
And S40, circularly detecting the natural water system and the sewage pipe network upstream sub-basin one by one according to the upstream and downstream confluence topological relation table of the sub-basins where the natural water system and the sewage pipe network are located, and sequentially allocating continuous confluence calculation serial numbers to the sub-basins according to the sequence in which the upstream sub-basins can smoothly complete confluence calculation until all the sub-basins have confluence calculation serial numbers.
In the present invention, the fact that the upstream sub-basin can smoothly complete the convergence calculation means that the sub-basin has no upstream sub-basin; or all the upstream sub-watersheds of the corresponding natural water system and the sewage pipe network have the confluence operation serial number, namely when one sub-watersheds carries out confluence operation, the natural water system confluence process and the sewage pipe network confluence process of the upstream sub-watersheds are required to be completed, so that when the confluence operation is carried out on the current sub-watersheds, the natural runoff and the sewage inflow amount obtained by calculation of the upstream sub-watersheds can be directly used; and when the sub-basin has no upstream sub-basin, the upstream natural runoff and the sewage inflow amount are both 0, and the current sub-basin confluence algorithm is not influenced. If the sub-basin having no confluence operation number exists in the upstream sub-basin (the upstream sub-basin of the natural water system or the sewage pipe network), and the sub-basin cannot complete the confluence operation, the next sub-basin is directly skipped to detect, and when the next cycle is carried out, the upstream sub-basin is detected again.
In the present invention, as shown in fig. 3, step S40 includes the steps of:
step S41, setting the convergence calculation sequence number array runId (1: n) of all sub-domains in the whole convergence calculation system to 0, which indicates that the convergence calculation sequence number calculation is not completed in all sub-domains; the current convergence operation serial number nowId is set to 0, which means that no convergence operation serial number is assigned to any sub-domain, and n is the number of sub-domains in the entire convergence operation system.
And step S42, setting the traversal sequence number S of the current sub-basin to be 0, and starting to traverse the sub-basins one by one according to the upstream and downstream confluence topological relation table of the sub-basins where the natural water system and the sewage pipe network are located.
Step S43, judging whether S is n, if yes, executing step S42; otherwise, step S44 is executed.
In step S44, let S be S +1, and the next sub-basin starts to be detected.
Step S45, determine whether the current convergence operation number runId (S) of the sub-basin is 0, if yes, execute step S46; otherwise, step S43 is executed.
Step S46, determining whether the current sub-basin has a sub-basin upstream of the natural water system or an upstream sub-basin of the sewage pipe network, and an upstream sub-basin with a confluence algorithm serial number of 0, if yes, executing step S43; otherwise, step S47 is executed.
Step S47 represents adding one sub-domain in which the convergence operation can be smoothly completed, and assigning the value of nowId to the convergence operation number runid (S) of the current sub-domain.
Step S48, judging whether the nowId is equal to the number n of the sub-watersheds, if so, executing step S49; otherwise, step S43 is executed.
Step S49, the routine ends.
The calculation process of the confluence operation number will be described in detail below with reference to fig. 2 and table 1 as an example.
A first loop traversal is performed on table 1:
for the sub-basin 1, since the sub-basin 2 is the upstream sewage pipe network sub-basin and the current convergence operation serial number of the sub-basin 2 is 0, the convergence operation serial number of the sub-basin 1 cannot be set; the sub-basin traversal sequence number s is increased progressively to judge the sub-basin 2, and as for the sub-basin 2, no upstream sub-basin exists, the convergence operation sequence number of the sub-basin 2 can be set to be 1; the traversal sequence number of the incremental sub-basin is judged, and as for the sub-basins 3 to 6, because all the sub-basins exist in the upstream sub-basin and the corresponding upstream sub-basin has the condition that the convergence calculation sequence number is equal to 0, the convergence calculation sequence number cannot be assigned; for the sub-basin 7, since there is no upstream sub-basin, the number of the bus operation can be set, and since the sub-basin 2 is set with the number of the bus operation 1, the number of the bus operation of the sub-basin 7 is set to 2 in sequence; similarly, the convergence operation serial number of the sub-basin 12 is set to be 3; the convergence operation number of the sub-basin 13 is 4; the sub-basin 14 has an upstream sub-basin of the sewage pipe network, which is the sub-basin 3, and at this time, the sub-basin 3 has no converging operation serial number, so that the converging operation serial number cannot be assigned, and the first cycle traversal is finished.
A second loop traversal is performed on table 1:
for the sub-basin 1, since the confluence operation number of the sub-basin 2 is 1, the sub-basin 1 meets the standard that the operation can be completed smoothly, and the confluence operation number of the sub-basin 1 is set to be 5; similarly, the convergence operation serial number of the sub-basin 3 is set to 6; for the sub-basin 4, the upstream sub-basin 14 does not complete the setting of the serial number of the convergence operation, so that the assignment cannot be made; similarly, the convergence operation number of the sub-basin 5 is set to 7, the sub-basins 6, 8, 9, 10 cannot be set, and the convergence operation numbers of the sub-basins 11 and 14 are set to 8 and 9, respectively; and ending the second cycle traversal.
Note that in the second round of traversal, the sub-domains 2, 7, 12, and 13 do not need to be determined again because the bus operation numbers are already set, and therefore they are skipped directly in the second round of traversal.
And continuing to perform the third, fourth and fifth loop traversal of table 1 until all 14 sub-domains have the merge operation serial number, at which point the process ends.
And step S50, determining the convergence calculation sequence of each sub-basin in the distributed water quality model according to the convergence calculation sequence number.
In step S40, the calculated convergence operation sequence number is the model operation sequence, but in the actual model calculation, if the convergence operation sequence number is searched from 1 to 14 according to the sub-domain sequence numbers for operation, it is not efficient to go through continuously and search and calculate the sub-domains one by one according to the convergence operation sequence number, so the convergence operation sequence number sequence needs to be processed, and the actual calculation only needs to be performed for 14 (number of sub-domains) times;
in the present invention, step S50 includes the steps of:
step S51, constructing a convergence arithmetic sequence array runSub (1: n), and initializing to 0, wherein runSub (i) represents the sub-basin code of the ith operation; setting a current operation serial number r to be 1;
step S52, setting the traversal sequence number S of the current sub-basin to 0;
step S53, let S be S +1, and determine whether the traversal sequence number S is greater than the number n of sub-domains, if yes, execute step S52; otherwise, go to step S54;
step S54, determine whether the current convergence operation sequence number runId (S) of the sub-basin is equal to the previous operation sequence number r, if yes, execute step S55; otherwise, go to step S53;
step S55, assigning the current sub-stream field coding to runsub (r), and making r ═ r + 1;
step S56, judging whether the current operation sequence number r is larger than the number n of the sub-watersheds, if so, executing step S57, otherwise, executing step S54;
step S57, the routine ends.
The calculation process of the confluence operation number will be described in detail below with reference to fig. 2 and table 1 as an example.
Increasing in sequence according to r ═ 1 to n, and performing first cycle traversal on table 1: when r is 1, runSub (1) is 2; when r is 2, runSub (2) is 5; sequentially obtaining runSub (3) ═ 12 and runSub (4) ═ 13;
a second loop traversal is performed on table 1: obtaining runSub (5) ═ 1, runSub (6) ═ 3, runSub (7) ═ 5, runSub (8) ═ 11, runSub (9) ═ 14;
a third loop traversal is performed on table 1: obtaining runSub (10) ═ 4 and runSub (11) ═ 10;
a fourth loop traversal is performed on table 1: to obtain runSub (12) ═ 9;
a fifth round-robin traversal is performed on table 1: obtaining runSub (13) ═ 6 and runSub (14) ═ 8;
in the actual model calculation process, the sub-basin of the i-th calculation, runsub (i), is obtained in sequence from r 1 to 14.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
