Detailed description of the invention
According to Figure of description, more detailed explanation is carried out to the cooling tower systems based on network without center of the utility model embodiment below.
Shown in composition graphs 1, embodiment of the present utility model discloses a kind of cooling tower systems based on network without center, comprising: multiple cooling tower and multiple cooling tower controller.
Wherein, multiple cooling tower is arranged in parallel, multiple cooling tower controller is connected with multiple cooling tower correspondingly, wherein, all cooling tower controllers are interconnected to form network without center, when cooling tower controller judges to reach certain trigger condition, cooling tower controller is for initiating adjustment task, when there is the cooling tower controller of initiating adjustment task in systems in which, the cooling tower controller that cooling tower controller starts to be adjacent carries out information interaction, and the operational factor after determining the optimization of every platform cooling tower after several times information interaction, cooling tower controller controls corresponding cooling tower according to the operational factor after optimization and reaches corresponding running status, and when not initiating the cooling tower controller of adjustment task in systems in which, keep corresponding cooling tower operational factor constant.
As shown in Figure 1, cooling tower systems comprise n (usual n be greater than 1 positive integer) cooling tower of individual parallel connection, each cooling tower is configured with a cooling tower controller.Shown in composition graphs 1, the way of realization of the network without center that multiple cooling tower controller is formed can be the combination both in cable network and wireless network one or both of.That is, can be connected by cable network, wireless network or the integrated network in conjunction with wire and wireless two kinds of forms between multiple cooling tower controller, form network without center.It should be noted that, network without center in the utility model embodiment can adopt various communications protocols to communicate, as long as real-time and the validity of communication can be ensured, that is, the network without center of the utility model embodiment is not limited to any concrete communication control processor, as long as the network service that meets the demands can be carried out and control, thus, node control network herein or network can carry out understanding and limiting with implication in technical field comparatively widely.
Composition graphs 1 again, each cooling tower controller can also be connected with the valve in cooling tower water route, to realize the start and stop in cooling tower water route by controlling corresponding valve; Each cooling tower controller is also connected with the fan of corresponding cooling tower, to control respective fans the reaching rotating speed needing start and stop state and needs.
When certain cooling tower controller judges to reach certain trigger condition, then initiate adjustment task by this cooling tower controller.
In concrete example of the present utility model, every platform cooling tower controller all can initiate adjustment task, and when wherein adjustment task initiated by a cooling tower controller, remaining cooling tower controller then coordinates the computing of this cooling tower controller completion system.
In addition, due to the multiple cooling tower controllers structures in the utility model embodiment are network without center, the control program that each cooling tower controller runs is identical, therefore, likely within the identical or close time, multiple cooling tower controller all meets task initiates condition and initiates adjustment task, for this situation, system needs to arrange corresponding treatment mechanism, in an embodiment of the present utility model, can be processed by the following two kinds mode.
One, the arbitration mechanism of post processing is first calculated, specifically, first, calculate one time respectively for each adjustment task, several non-stop layer cooling tower controller has connected to form non-stop layer computing network, is equal to an operating system, multi-task parallel process is supported under this system, thus, when there being multiple cooling tower controller to initiate adjustment task simultaneously, system can simultaneously computing, obtains multiple result.And then by arbitration mechanism, select and perform the result which regulates task.
Two, the arbitration mechanism calculated afterwards is first processed, specifically, first determine that who initiates adjustment task by arbitration mechanism, then adjustment task is initiated by it, that is: when running into multiple cooling tower controller and initiate adjustment task simultaneously, first select a promoter by arbitration mechanism, then initiate adjustment task by it.
Because first the arbitration mechanism first processing rear calculating is determined which cooling tower controller to initiate adjustment task by, therefore, the arbitration mechanism of post processing is first calculated relative to the first, amount of calculation is few, therefore, as a rule, the second can be used first to process the arbitration mechanism of rear calculating to reduce amount of calculation.
In an embodiment of the present utility model, the form of arbitration mechanism is also various, include but not limited to following several mode: in advance by artificial assigned priority, decide to take which kind of operation result according to the priority set in running, draw lots, rob token, random appointment etc.
Wherein, arbitration mode is to protect cooling tower not want frequent start-stop, the adjustment task no matter which platform cooling tower controller is initiated, its the possibility of result obtained is all optimal result, but generally have the cooling tower of multiple stage same model in system, as T1, T2, T3, the cooling tower of three same models, several groups of results calculated open [T1, T2], [T1, T3], [T2, T3], and current what running is these two cooling towers of T1 and T2, in order to avoid the frequent start-stop of water pump, frequent switching, arbitration result should be selected to open [T1, T2] corresponding scheme.
About trigger condition, in concrete example of the present utility model, trigger condition can have various ways, as the form of (1), (2) below.
(1) can determine according to the time, such as, set a control cycle for each cooling tower controller, often spend the regular hour and just initiate Primary regulation task by this cooling tower controller; Such as the control cycle of cooling tower controller can be set to 5 minutes, during each arrival control cycle, corresponding cooling tower controller first initiates request task, read group total is initiated to cold station system, read group total initiated by controller such as to coolant pump, obtain the total flow of current cooling water, then start to calculate.
(2) coolant pump side slat part triggers: when the operating condition of coolant pump there occurs change, as frequency there occurs change or number of units there occurs change, these all can cause the change of cooling water flow, now coolant pump group calculates current cooling water flow, then initiatively cooling tower is issued, after cooling tower receives information, initiate adjustment task, regulate.
When there is the cooling tower controller of initiating adjustment task in system, the cooling tower controller that the cooling tower controller in system starts to be adjacent carries out information interaction.
The process of information interaction is the process that a chain type calculates, and the process below for the information interaction of cooling tower is described in detail.
The control of cooling tower systems is divided into cooling tower unit number control (namely opening the water route of how many cooling towers) and cooling tower fan control (namely selecting cooling tower fan whether open and should be operated in what frequency) two subsystems, is described respectively below.
The main energy-consuming parts of cooling tower systems is cooling tower fan, its power and cold are compared relatively little with water pump, thus in order to ensure that cold is operated under higher efficiency, the cooling capacity of cooling tower systems should be made full use of, reduce the water temperature of cooling water as far as possible, increase in the energy consumption that the fan of cooling tower systems brings is insensitive for whole cold station system, can determine that the control thought of the unit number control of cooling tower systems is thus: the high-temperature cooling water flowed out from the condenser side of cold should be tried one's best and is assigned to each cooling tower equably, namely in the conceived case, as often as possible open the cooling water water route (even the valve open on cooling water pipeline) of cooling tower, cooling water is made to flow uniformly through each cooling tower to make full use of the heat exchange area of cooling tower.
And the control thought of the fan control of cooling tower is: frequency conversion unified by the fan of the cooling tower that water route is opened, and total leaving water temperature of controlled cooling model Tower System reaches setting value.
But the control in cooling tower water route also has a controlled condition, the cooling water flow flowing through each cooling tower exactly should not too small (such as can not be less than 40% of this cooling tower metered flow), otherwise can cause cooling water between each cooling tower, distribute inequality on the contrary, adverse influence is caused to the cooling of cooling water, therefore need the cooling water flow for every platform cooling tower that a lower limit is set, at the flow of every platform cooling tower higher than lower water route of as often as possible opening cooling tower in limited time.
Thus, the unit number control problem of cooling tower can be converted to the assignment problem of cooling water total flow, namely when given cooling water total flow ∑ G (this value can be the cooling water total flow that outside passes over), how to select to open which platform cooling tower, the flow that every platform is opened is not less than lower limit G
* i, the number of units of simultaneously opening is maximum.
Composition graphs 2, addresses this problem and can adopt following algorithm:
First by spanning tree process, all cooling tower controllers are formed a link, chain two ends are respectively start node v
1with terminal node v
m, or be called first-in-chain(FIC) and last-of-chain, then along chain node-by-node algorithm, terminal node does final decision after calculating, then pointwise passback result.Whole search procedure once completes, and without the need to loop iteration, specific algorithm is:
1) chain first launch task, propagates spanning tree (chain) instruction, until last-of-chain;
2) return spanning tree instruction by last-of-chain pointwise, complete the foundation of spanning tree;
3) start to calculate at first-in-chain(FIC) and outwards transmit following information, the value ∑ G (the cooling water total flow of system) when oneself is closed and value ∑ G-G when oneself opening
* 1, G
* 1for cooling water flow lower limit when first-in-chain(FIC) cooling tower works, and pointwise performs operation below;
4) after each node receives information (being an array comprising k), for every number wherein, calculating and oneself do not open and open and the amount of remaining cooling water in limited time under being operated in cooling water flow, then new array (for comprising the array of 2k number) being issued its neighbor node;
5) after the node of end receives data, in internal calculation, minus number is got rid of and (is less than zero and shows that this flux lower limit sum of opening the lower each cooling tower of combination is greater than cooling water total flow, thus after actual unlatching, the actual flow that every platform cooling tower is got is less than flux lower limit), and find the immediate value with zero, the combination of cooling tower corresponding is with it final running scheme.Then all nodes are passed this combination to passback.
6) each node knows oneself whether right start and stop situation.
Which adopts node-by-node algorithm, and each node is considered participate in or do not participate in combination two kinds of situations simultaneously, thus forms a pyramidal framework, as described in Figure 2.Mean and pass to last node, after last node completes combination calculating, total 2m combination, which includes situation about all not participating in.So this algorithm enumerates all combined situation in limited step, be complete.
If it should be noted that, joint of the chain tail has the value of multiple scheme identical when calculating and being, then select according to following principle: in order to avoid the switching of frequent start-stop, that group that prioritizing selection physical distance is nearest.
Illustrate the control method of cooling tower fan below:
The air-blower control rule of cooling tower is as follows: as long as the water valve of this cooling tower is opened, namely this cooling tower comes into operation, and its blower fan is opened; The blower fan opened unifies frequency conversion, the leaving water temperature of controlled cooling model tower, reaches water outlet temperature setting value (control algolithm that the given employing of setting value is other); If the rotating speed of frequency conversion fan reaches the lower limit of rotating speed, then close a Fans; If the rotation speed of fan opened reaches the upper limit, and still has the blower fan of the cooling tower of valve opening not open, then increase a Fans.
Operational factor after system determines the optimization of every platform cooling tower, cooling tower controller controls corresponding cooling tower according to the operational factor after optimization and reaches corresponding running status.
If do not initiate the cooling tower controller of adjustment task in system, then the cooling tower in system keeps original operational factor constant.
In above-mentioned computational process, the cooling tower flux lower limit value of needs can be built in the middle of cooling tower controller.
