As shown in figure 1, a kind of sub-basin based on sewage network topological relation that the present invention is provided confluxes, calculation order is counted
Calculation method, comprises the following steps：
Step S10, foundation natural waterway divide sub-basin, and are encoded, and each sub-basin is had unique coding.
In step slo, the coding scheme of sub-basin is continuous since 1 is incremented by, and without repeated encoding between sub-basin.As schemed
Shown in 2, whole example basin is divided into by 14 sub-basins according to natural waterway, to each sub-basin assignment unique number (Fig. 2
In numeral 1 to 14), as long as need exist for explanation be when being encoded each sub-basin to sub-basin coding repeat i.e.
Can, no matter which kind of method sub-basin coding is carried out in, different sub-basin coding schemes are drawn, the inventive method is not influenceed
It is follow-up to calculate.
Step S20, encoded according to natural waterway flow concentration path and sub-basin, sub-basin where building natural waterway is upper and lower
Topology relation table of confluxing is swum, that is, obtains the sub-basin number information immediately upstream of the relative natural waterway of each sub-basin.
In step S20, first according to natural waterway flow concentration path (Fig. 2 dotted lines) topological relation, each sub-basin is obtained
With respect to the upstream topological relation information of natural waterway, (corresponding with Fig. 2) as shown in table 1, wherein, upstream " m " coded representation is natural
The upstream sub-basin coding in current substream domain is imported in water system, m represents which the upstream sub-basin, sub-basin in current substream domain
It is encoded to " 0 " and represents do not have upstream sub-basin, more than the encoding value that " 0 " represents the corresponding upstream sub-basin of the sub-basin；" on
Alien basin number " is equal to the non-zero number of all upstreams " m " encoded radio, and this numerical value is used for statistical computation, does not influence to calculate sequence
Row.
Step S30, according to sewage network flow concentration path and subflow Field Number, sub-basin where building sewage network is upper and lower
Topology relation table of confluxing is swum, that is, obtains the sub-basin number information immediately upstream of the relative sewage network of each sub-basin.

Sequencing is followed successively by the continuous calculation sequence number of confluxing of sub-basin distribution, until all sub-basins all have calculation sequence number of confluxing.
In the present invention, it refers to that the sub-basin does not have upstream sub-basin that upstream sub-basin can smoothly complete calculation of confluxing；
Or all upstream sub-basins of its corresponding natural waterway and sewage network have all had the son of calculation sequence number of confluxing, i.e.,
Basin conflux when calculating, it is desirable to which the natural waterway Process of Confluence and sewage network Process of Confluence in alien basin are complete thereon
Into, so, current substream domain conflux calculation when, it is possible to directly using upstream sub-basin calculate obtained by natural path
Stream and sewage inlet；And when sub-basin does not have upstream sub-basin, illustrate that its upstream natural runoff and sewage inlet are
0, do not influence current substream domain to conflux calculation.For there is upstream sub-basin (the upstream sub-basin of natural waterway or sewage network)
The sub-basin of calculation sequence number of not confluxing, for the sub-basin can not complete to conflux the situation of calculation, then directly skips, and detects next
Individual sub-basin, when next round circulation is entered, then re-starts detection to alien basin thereon.
In the present invention, as shown in figure 3, step S40 is comprised the following steps：
Step S41, the calculation sequence number array runId (1 that confluxes that all sub-basins in whole calculus system of confluxing are set:n)
=0, represent that all sub-basins do not complete calculation sequence number calculating of confluxing；The current calculation sequence number nowId=0, table of confluxing is set
Show not for the distribution of any sub-basin is confluxed calculation sequence number, n is the number in calculus system neutron basin of entirely confluxing.
Step S42, the traversal sequence number s=0 for setting current substream domain, on the sub-basin according to where natural waterway and sewage network
Downstream is confluxed topology relation table, and beginning travels through sub-basin one by one.
Step S43, judge whether s is n, if it is, performing step S42；Otherwise, step S44 is performed.
Step S44, s=s+1 is made, start to detect next sub-basin.
Step S45, judge current substream domain conflux calculation sequence number runId (s) whether be 0, if it is, perform step
S46；Otherwise, step S43 is performed.
Step S46, judgement current substream domain are with the presence or absence of natural waterway upstream sub-basin or the upstream subflow of sewage network
Domain, and have the upstream sub-basin of calculation serial number 0 of confluxing, if it does, performing step S43；Otherwise, step S47 is performed.
Step S47, nowId=nowId+1 is made, representing increases a sub-basin that can smoothly complete calculation of confluxing, and
NowId values are assigned to calculation sequence number runId (the s)=nowId that confluxes in current substream domain.
Step S48, judge whether nowId is equal to sub-basin number n, if it is, performing step S49；Otherwise perform step
S43。
Step S49, end program.
Below with Fig. 2 and Biao 1 as specific embodiment, the calculating process to calculation sequence number of confluxing is described in detail.
First time searching loop is carried out to table 1：
For sub-basin 1, because sub-basin 2 is its upstream sewage network sub-basin, and sub-basin 2 confluxes calculation at present
Serial number 0, therefore sub-basin 1 cannot be set conflux calculation sequence number；It is incremented by sub-basin traversal sequence number s, sub-basin 2 is sentenced
Not, for sub-basin 2, serial number 1 is calculated due to all not having upstream sub-basin, therefore sub-basin 2 can be set to conflux；It is incremented by
Sub-basin traversal sequence number differentiated, sub-basin 3 to for sub-basin 6, due to all there is upstream sub-basin, and it is corresponding on
There is the situation that calculation sequence number of confluxing is equal to 0 in alien basin, it is impossible to calculation sequence number assignment of confluxing is carried out to it；Sub-basin 7 and
Speech, due to not having upstream sub-basin, therefore can set calculation sequence number of confluxing, because sub-basin 2 is provided with calculation sequence number of confluxing
1, therefore sub-basin 7 confluxes that to set gradually be 2 to calculation sequence number；Similarly, set sub-basin 12 conflux calculation serial number 3；Subflow
Conflux and calculate serial number 4 in domain 13；There is a sewage network upstream sub-basin in sub-basin 14, be sub-basin 3, and now sub-basin
3 do not conflux calculation sequence number, so calculation sequence number assignment of confluxing cannot be carried out to it, so far first time searching loop terminates.
Second searching loop is carried out to table 1：
For sub-basin 1, due to the calculation serial number 1 of confluxing of sub-basin 2, therefore sub-basin 1 is that satisfaction can be smooth
The standard of calculation is completed, the calculation serial number 5 of confluxing of sub-basin 1 is set；Similarly, the calculation sequence number of confluxing of sub-basin 3 is set to
6；For sub-basin 4, alien basin 14 does not complete calculation sequence number of confluxing and sets thereon, therefore can not be to its assignment；Similarly, if
The calculation serial number 7 of confluxing of sub-basin 5 is put, sub-basin 6,8,9,10 cannot be set, and set the remittance of sub-basin 11 and sub-basin 14
Stream calculation sequence number is respectively 8 and 9；So far second searching loop terminates.
It should be noted that in second searching loop, sub-basin 2,7,12,13 is due to being already provided with calculation of confluxing
Sequence number, it is not necessary to differentiated again, so directly being skipped in second searching loop.
Continuation carries out third time, the 4th time, the 5th searching loop to table 1, is drilled until 14 sub-basins all have to conflux
Sequence number is calculated, now terminates program.
Step S50, according to confluxing calculation sequence number, determine that confluxing calculation of each sub-basin in distributed water quality model is suitable
Sequence.
In step s 40, calculate gained conflux calculation sequence number be exactly model calculation sequentially, but realistic model calculate when
Wait, computing is carried out if confluxing from 1 to 14 search by sub-basin sequence number and calculating sequence number, need constantly traversal, drilled by confluxing one by one
Calculate sequence number search and calculate sub-basin, inefficiency, accordingly, it would be desirable to process calculation sequence number sequence of confluxing so that actual meter
Circulation 14 (sub-basin number) is only needed to when calculation secondary；
In the present invention, step S50 is comprised the following steps：
Step S51, structure conflux calculation order array runSub (1:N), and it is initialized as 0, wherein, runSub (i) tables
Show the sub-basin coding of i ＆ lt computing；Current operation sequence number r=1 is set；
Step S52, the traversal sequence number s=0 for setting current substream domain；
Step S53, s=s+1 is made, and whether judge traversal sequence number s more than sub-basin number n, if it is, performing step
S52；Otherwise, step S54 is performed；
Step S54, judge current substream domain conflux calculation sequence number runId (s) whether be equal to preceding computing sequence number r, if
It is to perform step S55；Otherwise, step S53 is performed；
Step S55, runSub (r) is assigned by current substream domain coding, and make r=r+1；
Step S56, whether current operation sequence number r is judged more than sub-basin number n, if it is, step S57 is performed, it is no
Then, step S54 is performed；
Step S57, end program.
Below with Fig. 2 and Biao 1 as specific embodiment, the calculating process to calculation sequence number of confluxing is described in detail.
Increase successively by r=1 to n, first time searching loop is carried out to table 1：As r=1, runSub (1)=2 is obtained；
Work as r=2, obtain runSub (2)=5；Obtain successively, runSub (3)=12, runSub (4)=13；
