Wherein, scheduler routine step includes following four steps:

S3.1, at current level h _chigher than turn on pump water level h _ohtime, Control and Schedule subsystem opens the pump that this pumping plant acquiescence starts.

S3.2, detect the current level h of current pumping plant _c, when the pump of this pumping plant is not all opened: if h _cbecome large, Control and Schedule subsystem opens the pump that in this pumping plant residual pump, flow is maximum;

If h _cdiminish, Control and Schedule subsystem maintains this pumping plant current state;

The rest processing capacity of S1.3, calculating sewage treatment plant;

S1.4, carry out walkthrough air-conditioning degree according to the rest processing capacity of sewage treatment plant;

After pre-evacuation step completes, system proceeds to best draining scheduling steps automatically, comprises following five steps:

The region importance that S2.1, control subsystem are served according to each pumping plant arranges dispatching priority;

S2.2, under the complete schedulable condition of pumping plant, adopt balance feasible flow scheduling draining or just unbalance feasible flow draining;

S2.3, under the schedulable condition of pump station part, adopt negative unbalance feasible flow scheduling draining according to the maximum emission water discharge allowed;

S2.4, under the condition of pumping plant non-scheduling, to remain stationary;

S2.5, then need when the water level in the water collecting basin having pumping plant exceedes emergency control waterline to carry out emergency control scheduling to it.

Wherein, under emergency control scheduling, when meeting other fraternal pumping plant feasible flows, ability draining maximum to the greatest extent.Assuming that the water level in water collecting basin not to be exceeded all fraternal child node pumping plant termination of pumping of emergency control waterline, calculate the residual drainage ability of the water inlet manifold of now downstream father node pumping plant; When this residual drainage ability prerequisite and supposition termination of pumping, other fraternal pumping plants, according to the sequential scheduling draining of priority, determine the turn on pump amount of fraternal pumping plant successively.

In pre-evacuation step, in order to retaining and the drainability of pumping plant can be given full play to, need before very heavy rains, pumping plant is carried out emptying in advance.Be specially, pumping plant resisted the Regulation capacity of heavy rain, be converted into the rainfall degree of depth, can in this, as under the different rainfall intensity of differentiation, the reference of ruuning situation opened by pumping plant.In conversion with emptying analysis, with pumping plant sump driving water level for reference, sewage treatment plant residual processing power is index, is scaled drainage area precipitation depth, determines that pumping plant needs the water yield of discharging in the empty scheduling scheme of walkthrough.

According to the flow-power characteristic N=f of pump ₂(Q) know, when flow one timing, corresponding power is certain, and the energy consumption E under certain power N was directly proportional to the time, and even pump works the t time under this power, then have:

E＝N·t

$E=f_2\left(Q\right)\&CenterDot;t=f_2\left(Q\right)\frac{V}{Q}$

$\frac{E}{V}=f_4\left(Q\right)=\frac{f_2\left(Q\right)}{Q}$

F in above formula ₄(Q) what represent is flow---the power consumption function of row's cubic unit water.

If there is energy consumption minimization value in operation interval working flow point time, then arrange one ton of water, needed for this dotted state work, energy consumption is minimum.Corresponding has a Q _bestmeet: family curve because of high efficiency range is continuous print, therefore Q _bestq in certain interval neighbouring can make relatively little, if choose an interval Q _best∈ Δ Q=[Q ₁, Q ₂], according to stage-discharge function h=f ₀(Q), then the SEA LEVEL VARIATION interval of its correspondence is Δ h=[h _sl, h _oh]

In the present embodiment, control subsystem is by being provided with the interval Δ h=of efficient working water level [h to each pumping plant _sl, h _oh]; Current level h _chigher than turn on pump water level h _ohtime, described control subsystem controls described scheduler subsystem turn on pump; Current level h _clower than termination of pumping water level h _sltime, described control subsystem controls described scheduler subsystem termination of pumping, thus the solution that the energy consumption realizing being applied in the utility model full pipe network is minimum.

In the utility model, when intelligent drainage function dispatching system is operated under normal circumstances, enable energy-saving distribution submodel, this energy-saving distribution submodel moves towards figure according to pumping plant distribution and pipe network is expressed as tree.

The storage organization of this tree adopts child's parents chained list representation.

The whole process of Fig. 2 adopts non-recursive depth-first traversal (postorder traversal formula) to tree.

Fig. 3 is that Fig. 2 solves operator process, represents when carrying out problem solving operation to certain node, first needs the set of feasible solution obtaining its all direct child node, this set of feasible solution is carried out the Candidate Set of input value when objective function solves as present node.

By the ergodic process of Fig. 2, obtain being applied to the scheduling scheme that the energy consumption of whole pipe network is minimum.

In the utility model, when intelligent drainage function dispatching system is operated under emergency rating, enable emergency scheduling submodel, this emergency scheduling submodel moves towards figure according to pumping plant distribution and pipe network is expressed as tree.

The whole process of Fig. 4 travels through according to priority from root node.

Fig. 5 is Fig. 4 scheduling operation subprocess, represents when carrying out scheduling operation to certain node, first judges its whether non-scheduling, whether complete schedulable.

If non-scheduling, negative unbalance feasible flow is adopted to dispatch; If schedulable completely, just unbalance feasible flow or balance feasible flow is adopted to dispatch; If part schedulable, negative unbalance feasible flow is adopted to dispatch.

By the ergodic process of Fig. 4, obtain the scheduling scheme of a pipe network.

Certainly, implement arbitrary product of the present utility model might not need to reach above all advantages simultaneously.
