Therefore, it can utilize and be used to control the system of compressibility according to the present invention to control the operation of compressor. In compressibility according to the present invention, control can be selected from user interface and adjust the pattern of compressor particular delivery.It is based on The selection carried out from user interface, the control of the conveying of compressor can be joined based on the conveying calculated according to network delivery request Examine value or as what is presented in figure 3 a is directly based upon network pressure setting or the setting of compressor specified pressure.
Particular compressor selection is directed to from user interface for adjusting the pattern of compressor.How the adjusting of compressor operates Depending on being directed to which control model compressor selects.The Adjust and use of compressor directly adjusts (for example, by changing rotating speed) Or by changing pressure setting or being realized by changing the discharge pressure reading of compressor.
Identical with the figure in Fig. 3 B if transportation request is selected as the control model of compressor, network delivery please Seeking Truth adjusted value, the adjusted value determine the direction of api request (or being more briefly directed to the requirement of fluid media (medium)), fluid media (medium) Variation and variation rate.Network delivery request according to embodiment of the present invention is described in Fig. 4 A to Fig. 4 C (0-100%'s) determines.As Fig. 3 B are presented, from user interface selection for the shaping modes of compressor.If directly join It examines (such as speed) and is selected as the method for adjusting compressor, then the transportation request of compressor is zoomed to the lattice needed for compressor Formula.If pressure setting is selected as shaping modes, network delivery request is converted into compressor transportation request, and into one Step is converted into the pressure for taking into account the limitation provided from user interface and sets.In this case, tune can be checked first Whole rate, can according to the value of the discharge pressure sensor of the size of compressor transportation request, its derivative and compressor and Derivative calculations go out new pressure setting.It, can be by two level in addition, if the pressure sensor of compressor oneself is on network side Pressure difference on processing unit is taken into account.If pressure data item is selected as shaping modes, rate inspection can be performed first It looks into, and the value identical with the pressure setting of compressor can be supplied to compressor for pressure transmitter signal.According to defeated Request is sent, if necessary to smaller conveying, then the value that can will be greater than above-mentioned value is set as described value, and if necessary to bigger Conveying, then smaller value can be set.Compressor according to one embodiment is presented in Fig. 5 and Fig. 6 in more detail Transportation request determines.
If compressor control pattern is network pressure setting, identical with the figure of Fig. 3 C, network pressure setting is adjustment Value, by comparing the reading of the adjusted value and control pressure sensor determine the requirement of fluid medium, fluid media (medium) side To variation and variation rate.Compressor shaping modes are selected from user interface, the shaping modes are currently considered In the case of can be directly reference, pressure setting or pressure data item.Network pressure setting can be for example converted into will be due to pressure The compressor pressure setting value that the pressure loss caused by the two stage treatment of contracting air is taken into account.If directly with reference in network Pressure is used as compressor shaping modes in the case of setting, then can perform the inspection of adjustment rate, can calculate network pressure How many force data item sets different from network pressure, and can be based on the information and change directly reference.Utilize slow adjustment Rate, variation is distributed to the desired period, and directly reference is also updated between the inspection of adjustment.If pressure is set The pattern for being used as adjusting compressor is put, then can perform the inspection of adjustment rate, and network pressure setting can be provided To compressor.If the sensor of compressor oneself not on network side, can be repaiied by the pressure difference on two stage treatment unit Positive setting.If pressure data item is used as adjusting the pattern of compressor, the inspection of adjustment rate can be performed, and can be with Calculate how many network pressure data item sets different from network pressure.Pressure transmitter to be used as can be corrected if necessary Signal is supplied to the pressure data item of compressor.
If compressor control pattern is the setting of compressor specified pressure, identical with the figure of Fig. 3 D, compressor is specific Pressure setting is adjusted value, and fluid media (medium) requirement, stream are determined by comparing the reading of the adjusted value and control pressure sensor The variation in the direction of body medium and the rate of variation.Compressor shaping modes are selected from user interface, which is working as It is preceding consider in the case of can be directly reference, pressure setting or pressure data item.If it is set in compressor specified pressure In the case of, directly with reference to shaping modes are used as, then the inspection of adjustment rate can be performed, compressor pressure can be calculated How many data item sets different from compressor specified pressure, and can be based on the information and change directly reference.Using slow Rate is adjusted, variation is distributed to the desired period, and directly reference is also updated between the inspection of adjustment.If pressure Power setting is used as adjusting the pattern of compressor, then compressor specified pressure setting is provided to compressor.If pressure data Item is used as adjusting the pattern of compressor, then can perform the inspection of adjustment rate, and can calculate compressor pressure number From compressor specified pressure how many sets different according to item.Pressure transmitter signal to be used as can be corrected if necessary to be supplied to The pressure data item of compressor.
Fig. 4 B describe network delivery request determine how progress.If network pressure is close to setting (that is, closer In the limiting value of setting), then check the rate of change of network pressure.It is defeated by quickly changing network if rate of change is big Request is sent to slow down variation, and if rate of change is small, slowly changes network delivery request.The mean change of network pressure It can be used for evaluating the rate of change of network pressure, and can be used as the setting of rate of change when checking rate of change Parameter, the setting are intended for network pressure close to the situation of setting (that is, in limiting value closer to setting).If net Network pressure then checks net further from setting (that is, outside limiting value closer to setting but in the limiting value further from setting) The rate of change of network pressure.If rate of change is big, slow down variation, and if become by quickly changing network delivery request It is small to change rate, then slowly changes network delivery request.The mean change of network pressure can be used for evaluating the variation of network pressure Rate, and can be used as parameter when checking rate of change for the setting of rate of change, the setting is intended for network Pressure is arranged distant from the situation of (that is, outside limiting value closer to setting but in the limiting value further from setting).If net Network pressure is arranged distant from (that is, outside limiting value further from setting), then quickly changes network delivery request.Rate of change is set It can be used as parameter when checking rate of change, the setting is intended for network pressure and is arranged distant from (that is, further from setting Limiting value outside) situation.
Fig. 4 C describe how the determining of network delivery request can further be in progress.It, can after the above process is performed To check for the variation of the quantity of the compressor needed for conveying air.If the quantity of required compressor changes, can With the compressor capacity by changing network delivery request compensation increase/reduction.If quantity does not change, other steps are not needed to Suddenly.The quantity and its conveying (quantity known to system and the conveying) for conveying the compressor of air can be used for needed for evaluation The quantity of compressor.
The figure of Fig. 5 presents determining for the compressor transportation request in the case of an embodiment of the invention.It is first First, the transportation request of determining compressor is asked according to network delivery.The limit of compressor adjustable range can for example influence this really It is fixed.After this, it checks the efficiency ratio of compressor, and changes the transportation request of compressor, so as to from the efficiency of compressor ratio Angle for as far as possible effectively.When evaluating compressor efficiency ratio, the efficiency ratio of currently considered compressor can be used Such as the efficiency curve of the compressor.
Fig. 6 presents example according to the embodiment of the present invention, wherein, compressor control pattern is transportation request, and And compressor shaping modes are pressure settings.Set-point can be selected, and can select via the user interface of control system Transportation request, network pressure setting or the setting of compressor specified pressure are selected, as the control model for compressor.In these Rong Zhong, for the example selection transportation request.Reference, pressure setting or discharge pressure reading can be selected to directly transport as use In the shaping modes of compressor.In this example, pressure setting is selected for use in adjusting the pattern of compressor.
In the embodiment of fig. 6, it is first determined network delivery asks (0-100%).The variation in the direction of network pressure The calculating can be all influenced with rate of change, with the difference of set pressure and the rate of change selected from user interface.After this, Determine the transportation request (0-100%) for compressor.It will be adjusted simultaneously via user interface when determining compressor transportation request Adjustable range available for compressor is taken into account.Finally, the pressure setting for compressor is determined, and here, such as can By by compressor always by efficiency as best as possible than use it is this in a manner of the efficiency curve of compressor taken into account. In the pressure setting for determining compressor, by the variation size of the adjustable range of compressor, transportation request value and described value and The value of the discharge pressure sensor of compressor is taken into account, and if in addition, the discharge pressure sensor of compressor oneself not On network side, then the pressure difference on two stage treatment unit is taken into account.
User can by select compressor control model and shaping modes and using selected adjusted value parameter come Optimize the operation of entire pneumatic system.Control system is suitable for control and the feed adjustment of all known type of compressor.In basis In the system of the present invention, to that can control and adjust together how many variable conveying compressors, there is no limit.This makes it possible to reality Now energy-saving benefit as best as possible.
In controller known in the art, the adjustable range of compressor remains fixed.However, in fact, compressor Adjustable range there is different sizes, and therefore without using the entire tune of the compressor in solution known in the art Adjusting range cannot select desired machine to come always with best efficiency than operation.This leads to the unnecessary consumption of energy.
In the inventive solution, network adjusted value is being converted into the transportation request for variable conveying compressor When, direction and its variable quantity of network api request can be calculated.The variation is distributed to each variable conveying compressor.Herein Later, about whether can for example by means of the efficiency curve of compressor along more energy efficient adjustment in direction require examined It looks into.
If one or more conveyings with bigger in compressor are in more preferably efficiency ratio and compressor Some have more preferably efficiency ratio with smaller conveying, then can take into account the effect of efficiency curve.If some are compressed Machine has more preferably efficiency ratio with smaller conveying, and even if the efficiency ratio of all machines will be conveyed more preferably with smaller, Capacity is also significantly greater than other compressors, then can also take into account the effect of efficiency curve.If a certain compressor is with more Big conveying has a more preferably efficiency ratio, and even if all machines efficiency than by with the conveying of bigger more preferably, capacity Noticeably greater than other compressors can also then take into account the effect of efficiency curve.
In a solution in accordance with the invention, with off-load and compressor can be stopped.In this case, it calculates variable The capacity that is wasted of compressor is conveyed, and if it is necessary, closing small compressor so that variable conveying compressor is with the defeated of bigger Send operation.
Controller known in the art can have for the off-load limit of compressor and the loading limit.In normal condition Under, in solutions known in the art, multiple variable conveying compressors are run with minimum conveying, in such case Under, pressure is very slowly promoted or is not promoted.Next compressor off-load only when reaching the off-load limit.This existing In technical solution, with poor efficiency than variable conveying compressor is driven to reach long time section.
In solution according to embodiment of the present invention, next the compressor of off-load is wanted in identification successively. In addition to this, the capacity that is wasted of variable conveying compressor is calculated.Do not include to obtain the compressor of off-load in this computation Capacity.According to the factor of safety that the deduction of the capacity of waste is provided from user interface or calculated automatically, thus to obtain being calculated The capacity that is wasted.The capacity deduction that is wasted according to being calculated will obtain the compressor of off-load at the time of current consideration Conveying.If the result calculated is just, off-load compressor.
The advantages of solution is significantly to perform the off-load of next compressor earlier, and with it is known in the art Solution compare the driving for reducing variable conveying compressor in inefficient range.Nargin safe to use can be to avoid The continuous loading of machine and off-load.If consumption fluctuation, lag can be used, this reduces " unnecessary " on/off switch.
Fig. 2 presents the example of the compressor off-load situation of the operation of system according to the embodiment of the present invention.
The region marked in Fig. 2 is defined as:
The compressor that 1=is currently running
The compressor that 2=has stopped
Next 3=wants the compressor of off-load
The variable conveying compressor that 4=is currently running
In the embodiment presented in Fig. 2, next identification wants the compressor of off-load (that is, in this case successively For compressor 2, because it has lowest priority (=4)).Next the conveying for wanting the compressor of off-load is 50%* at this moment 80m3/min=40m3/min.
After this, the capacity that is wasted of variable conveying compressor (region 4) being currently running is calculated:(100%- 75%) * 100m3/min+ (100%-75%) * 80m3/min=45m3/min.
Factor of safety is inferred according to the capacity being wasted, thus to obtain the capacity that is wasted calculated.If for example, safety The factor is 4m3/min, then the capacity that is wasted calculated is 45m3/min -4m3/min=41m3/min.
The conveying of the compressor of off-load is wanted in the capacity deduction that is wasted according to being calculated, and if final result is just, Then off-load compressor.As a result, for example, if factor of safety is 4m3/min, the final result realized is:45m3/min– 4m3/min -40m3/min=1m3/min.In other words, in the case of the factor of safety currently considered, off-load compressor.By This, if for example, factor of safety is 6m3/min, the final result realized is:45m3/min–6m3/min–40m3/min =-1m3/min.In the case of the factor of safety, not off-load compressor.
The compressor for wanting off-load may be fixed conveying or some other type of compressor.It can be transported with sub-load Capable all compressors (for example, frequency converter driving or turbo-compressor, more reciprocating piston compressors etc.) are considered as Variable conveying compressor.
It in a solution in accordance with the invention, can be from the adjustable range of the variable conveying compressor of UI Preferences. In this way, can be with best efficiency than operation compressor, and can discharge to avoid turbo-compressor.
The off-load and the loading limit of pressure are configured in some central controllers known in the art.It is also possible to It is that there is central controller pressure to set and load the limit or setting and the off-load limit.If controller can also drive variable Compressor is conveyed, then system also often has and set for the pressure of compressor.However, in combination known in the art, How variable conveying compressor and off-load-loading compressor will not be set as running together and taken into account.Problem especially occurs In the situation:Base load is run, and deposit at the following time together with variable conveying compressor:If the appearance of compressor Amount midway is terminated, then off-load-loading compressor enters use, is conveyed with support pressure.In this case, it is general happens is that Variable conveying compressor there are during enough capacity it is high or in running under pressure level.At the end of capacity, allow pressure It reduces, and when pressure reduces enough, starts and support compressor.
It in the inventive solution, can be by so that in a manner of the very close loading limit of the setting limit of loading machine For central controller setting off-load, the limit and the loading setting limit are set.Off-load is set between the limit and the loading setting limit Range can also automatically be calculated by studying pressure and fluctuation range by single variable conveying driven compressor.The solution party One advantage of case is in variable conveying compressor isolated operation, and pressure stage is lower, and can save energy.
In solutions known in the art, usually there are three set for tool in the central controller for compressor:Off-load Pressure, on-load pressure and setting pressure.In some compressors, with it is minimum may feed drive they when, start to dump Excess air.Significantly more work(when dumping excess air waste than being opened with minimum delivery operation and no outlet valve Rate.In some compressed air networks significantly fluctuated in consumption, there are very more, feelings of the operation in the minimum delivery limit Condition.
In a solution in accordance with the invention, positive normal pressure can be allowed more than (for example, in these types of cases) Power is set.In this case, for example, allowing turbo-compressor than being run under setting the higher pressure specified by pressure. In this case, turbine does not dump, and opposite drain valve remains turned-off.This realizes more preferably energy efficiency.
In a solution in accordance with the invention, off-load-loading compressor can be directed to and compressed for variable conveying Machine adds the different off-load limit.The limit of variable conveying compressor can be set to the pole higher than off-load-loading compressor Limit.Therefore, in this case, pressure is allowed slightly to be promoted in a network before compressor is allowed to dump.The limit for example may be used To be set via user interface.By using above-mentioned solution, reduction compressor dumps under minimum delivery, so as to reduce To the needs of power attenuation.
For compressor transportation request to control data further conversion (that is, the conveying of variable conveying compressor Adjustment) it in the inventive solution can be in many ways (for example, using derived from resolution ratio per minute, conveying percentage Than or pump blades posture direct reference) carry out.The adjustment of the conveying of variable conveying compressor can utilize pressure to set Change, be automatic or by simulation being set to carry out together with pressure network pressure data item.These methods are suitable for institute Have type of compressor, without tube model and make how.
In the system of the present invention, can be directed to compressor calculate adjusted value, the value specify can be supplied to compressor, The expectation conveying of compressor or pressure stage and the sensor for it is expected driven compressor.By means of this point, rotating speed or IVG are calculated Put alternative one, pressure setting or institute's analog network pressure data item alternative one, the value as compressor to be supplied to.Herein Later, compressor horsepower or cell pressure are measured.Based on the measurement data, so that the mode for reaching set-point is corrected and to be carried Supply the value of compressor.In this way, the compressor controlled with different control models can be controlled together with unified approach.Equally, may be used Easily to parameterize compressor from user interface.
By means of the system of the present invention, can be controlled with same controller has multiple and different compressed air networks or air Multiple and different factories of network.In this case, the controller of system of the invention can have for very more points Set-point, user interface and control logic.Can retain centered on can handle data and can be according to institute fast enough State the computer that data form control.System can also by it is following it is this in a manner of be configured:So that the interruption in computer network The generation of compressed air is not prevented.In this way, the platform for the server of enterprise group may be coupled to control device, and not Need individual system.This generates the saving of cost, and newer management is easier to by group.Equally, work can then be carried out Factory is specific or the specific comparison of pneumatic network.
In an embodiment of the system of the present invention, a compressed air network can be controlled in multiple portions System.In this case, a compressed air network is divided into multiple " virtual networks " in its control aspect.Compressed air network These parts controlled as individual entity.In such a case, it is possible to the pressure drop by the faster part of network It is low to take into account, and can be made a response in a manner of most preferably possibility to the pressure reduction.
If any one in selected compressor cannot operate, the system of the present invention can have emergent sequence. In this case, as the larger compressor of base load operation compressor it is a certain it is unforeseen due to and stop or It is placed in when not conveying air in the list for the selection for generating emergent sequence.Larger replacement compressor is arranged in emergent sequence In so that they enter earlier uses.When the system that detects returns to normal condition, emergent sequence can be interrupted automatically It uses.Operator can since user interface and interrupt emergent sequence use or can be automatic.
By means of the emergent sequence of the system according to the present invention, usually compressed not as the compressor of base load operation The compressor as base load operation is also used as in the case of machine failure, to replace usually as base load operation It is out of order or the compressor of stall.In this case, it is out of order in larger compressor and real in operation after the failure Now pressure evenly.In this case it is also possible to minimum operating pressure is calculated, and continuous section in the normal operation period Save energy.
In an embodiment of the invention, according to the setting provided in the user interface or by straight from user interface Selecting is selected, and compressor can be run in a manner of timing and have become hotter.After this, compressor is back to normal automatic drive It is dynamic.Special operating status can be constructed in the central controller (in addition to normal condition, also for the purpose of hotter operation Part, automatic, manual mode).Each compressor can be for example individually switched with timing mode or via user interface to current institute The state of consideration.Compressor is moved in terms of priority before other compressors, becomes the compressor for being very easy to driving. Compressor can be according to the compressor oil temperature (or other measurements) run through all phases/states or with timing mode from current The state considered be back to it is automatic or it is a certain it is other before state.Finally, compressor is no longer on priority list at it Stop during top and close.
Using above-mentioned solution, automatically hotter in a controlled manner it can be run and may insure to compress in stand-by compressor The clear and definite hotter operation of machine and can realize for being appropriately carried out required all phases/states when reduces manual work.It is however, standby The period of unnecessary length is not used in compressor.
In an embodiment of the invention, there may be particular point in network, and system can be by the particular point It takes into account.Therefore, if there are a certain vital points in network, the pressure in the place can be monitored, and can be in system It is middle that place is set as particular point.If pressure reduction, the setting for delivery end can be improved.Therefore, for major part Time, the pressure of delivery end can be relatively low, and when higher is needed to convey end pressure, which can be promoted to expectation etc. Grade.In this way, generate unnecessary high pressure without compressor.It is also possible to detection more quickly and the pressure stage of particular point have The spike effect of the consumption of pass, and when consumption spike is not present in network, network pressure can be kept relatively low.
In this embodiment, additional sensors can be added to consumption place and/or can be used and can be used in a network Measurement.There may also be the settings of the expectation minimum pressure for particular point.Furthermore it is also possible to exist for how many network pressures Power can be declined according to the parameter of particular point and controller or raised setting.Setting can be selected by operator.It can be with Compressor is controlled according to given setting and promotes network pressure grade.
In an embodiment of the invention, lower pressure network support higher pressure can be passed through in the case that desired Power network.In this embodiment, system can identify the pressure drop in elevated pressures network.Can also for Another reason and Start the support of the second network.In solution preferably, the second sequence is selected in lower pressure network, at this In sequence, the pressure stage higher of lower pressure network.After this, verification pressure is promoted in lower pressure network becomes high In the pressure of elevated pressures network.After this, valve is opened, to support elevated pressures network.It can be held when based on measurement verification During row, normal sequence can be back to.The return can also be realized from user interface.
In a system in accordance with the invention, each compressor can be directed to and set for pneumatic system minimum and maximum Pressure limit.When more than these values, the control of compressor is switched to the control system of themselves.Start and loading is compressed The sequence of machine is determined by sequence of operation table.
Compressor can be arranged to multiple sequence of operation table work as needed.This is possible, because each Independent operation sequence is the embodiment of its classification, can be made by the program parameter of the quantity of the determining embodiment of change With or deactivate.Therefore, reprogramming is not needed at all when adding or removing the sequence of operation.
By way of selecting to change the sequence of operation changing a control parameter.The sequence of operation can for example be based on week It goes through, the stopping of compressor or automatic setting change.The automatic required unloaded work(changed based on possible all compressor combinations The Continuous plus of rate, the Continuous plus and the unrestricted choice group that the observation of effective required compressor and observation to be kept to be spaced It closes ground and generates automatically selecting for the possible most effective sequence of operation.
It in an embodiment of the invention, then can be by limiting compressor if there is enough compressors Start to rotate compressor.For example, when being related to large-scale motor, startup can for example be limited to 2 times per hour.If it is required that it is Three 10 minute periods per hour, then preceding 2 periods are by a compressor operating, and the last one period is by another compression Machine is run.This can reduce excessive zero load.Rule can be that compressor is specific, and they can for example utilize center control Device is set.
The method for starting and stopping compressor being selected via user interface.These methods be using continuous signal or The startup and stopping that pulse carries out, and the startup based on allowed quantity and operate stopping or stopping.
Startup, loading and the off-load delay of each compressor can be individually adjusted.This allows method under any circumstance Correct operation, but regardless of pneumatic system oneself dynamics how.
Compressor controller reads information from compressor, and will send information to control program, from a group control program read (CP read) Take control command, and while the condition for also monitoring the validity of order and data communication bus and program according to it from Oneself control program execution command.In existing solution, even to be incorporated in the single non-standard pressure under control system Contracting machine model is also required to carry out relatively wide modification to control program.This problem is only limitted to simple compression machine controller now The modification of program.When the solution is successful, even this modification can be also reduced, because this will be easy to Form the library of compressor controller program.
Control program can continuously calculate total output and the power input of pneumatic system.These data can be stored in greatly On capacity storage medium.In the user interface, these data can be present in same figure so that can at every moment be schemed Shape form watches these data.In addition, mean consumption and power during the period selected by user interface calculating.Moreover, figure Point can be Printed to File with desired time interval.Resulting report allows to verify the practical effect generated by control system Benefit even can continuously measure execution with long duration.
Information received via data communication equipment by control program, related with compressor state and pressure value is continuously deposited Storage is in the large-capacity storage media in may be at control computer.The mode of operation and pressure stage of compressor can be presented on In same figure so that at every moment can graphically watch them.This makes it possible to real-time or its post analysis pneumatic system Operation.
The basic framework of method allows the device of arbitrary manufacturer in compressor controller.This allows to this Invention is in impossible many situations before it.
When (for example, connecting fault) is interfered to appear in the arbitrary portion of system, compressor controller, which will control, to be switched To the control system of compressor oneself.The noiseless production of compressed air in the case of this guarantee is nearly all.
By means of group controller or it can will run any device test compression that controller is write with loading command The operation of machine controller.This is realized by the structure of director demon, in this configuration, no matter type of compressor and model How, external interface can be made to keep as simple as possible and standard.It only runs/ceases and desist order and lead to required load factor Cross interface write-in.
It is apparent to those skilled in the art that the present invention different embodiments be not limited solely to it is described above Example, but them can be changed in the range of claims presented below.
