Embodiment
The present invention is explanation in detail with reference to the accompanying drawings and below.
Fig. 1 shows an installation drawing, and one embodiment of the invention are described.
In Fig. 1, technological process simulator 10 utilizes technological process data server 20 and receives technological process data from entity factory 30.
10 of technological process simulators and entity factory 30 come into operation synchronously.When entity factory 30 provided the technological process data to technological process simulator 10 each time, technological process simulator 10 was just revised the calculating formula parameter of the realistic model in the technological process simulator 10, and calculates.Technological process simulator 10 is then exported result of calculation.These results just become emulation output.
Fig. 2 explanation is according to an entity apparatus example of the plant operation support system of Fig. 1.In Fig. 2, the assembly general with Fig. 1 is marked by the numbering identical with Fig. 1.
Technological process simulation architecture 102 uses realistic model 103 to carry out the technological process emulation of entity factory 30 runnings.This technological process emulation is to carry out synchronously with the running of entity factory 30.
The data of the inductor (not shown) in the entity factory 30 are sent in the parameter correcting device 101 by technological process data server 20 and input interface unit 104.
105 of parameter determination devices are selected the parameter revised according to the relation between the variable of plant data and realistic model 103.The change of parameter can have influence on final simulation result in the realistic model 103.Parameter determination device 105 is selected the parameter with height association in advance according to factory's log-on data or the analysis result of model formula.
The technological process data that the utilization of 101 of parameter correcting devices is supplied are revised those continuously by the selected parameter of parameter determination device 105.Parameter correcting device 101 is to come corrected parameter in the mode that the actual output with the emulation output of technological process emulation mechanism 102 and entity factory 30 is complementary.
Corrected parameter is sent in the technological process emulation mechanism 102.The technological process emulation that comprises physics and chemical model formula is then calculated according to these corrected parameters.The result of emulation is stored in the emulated data server 106.According to the data of these storages, technological process emulation mechanism 102 can allow display device 107 demonstrate the physical quantity that a certain place can't be measured in reality.In addition, in the result of calculation of emulation, technological process emulation mechanism 102 also can allow display device 107 demonstrate can't be in entity factory 30 characteristic of detected technological process data and device or material.
Emulation is carried out in corrected realistic model 103 runnings real-time and entity factory 30 of technological process emulation mechanism 102 operation parameters synchronously.
With the running synchronization simulation of entity factory 30 time, system of parameters is revised in the mode that the output with the output of realistic model 103 and entity factory 30 is complementary.
Instruction is provided and technological process simulators 10 synchronous and 30 runnings of entity factory are operated with the running speed that is higher than entity factory 30 the operator of factory, make and learn anticipation trend, so just treat as primary data and receive by primary data generation device 108 in the result of the technological process emulation of a special time in (for example before several minutes or before a few hours) before the schedule time.Afterwards, be the primary data that produces high-speed simulation.Primary data herein is supplemental characteristic, setting situation of realistic model 103 or the like.
Future anticipation device 109 utilizes these primary datas and by time of technological process simulator 10 is quickened to calculate with for example several times or even the hundreds of times of high speeds to the usual time.In addition, future anticipation device 109 is with the real data of preset time reception from entity factory 30, and the parameter (state variable) of correction realistic model 103.
Future anticipation device 109 shows the simulation result of future trend on display device 107.In addition, future trend device 109 transmits the simulation result of future trend to control part 111, so that it is fed back to the control of entity factory 30.
Factory's diagnostic device 110 provides factory's diagnosis by the corrected parameter value of more present emulation and the corrected parameter value of emulation in the past.
Factory's diagnostic device 110 changes the parameter of present technological process emulation with parameter variation in the realistic model 103 in the technological process emulation in the past compares, if this both difference surpasses a predetermined tolerable value, just this difference is unusual and to control part 111 reports as factory, and utilize on the display device 107 the picture indication and with this difference notice operator of factory.In other words, if the parameter of technological process emulation now changes and significantly departs from the parameter that saves as past data and change, factory's diagnostic device 110 just can be with this both variance reports become factory unusual.Control part 111 is a controller, its provide the operation amount designation data to entity factory 30 or the data that entity factory 30 is provided to technological process emulation mechanism 102.
Afterwards, factory's diagnostic device 110 utilizes the model formula of realistic model 103 to predict which malposition of entity factory 30.
In addition, factory's diagnostic device 110 checks just whether the data calculated by technological process emulation mechanism 102 are with consistent from the obtained real data of entity factory 30, if this both difference surpasses a predetermined tolerable value, show on display device 107 that just this difference is that a factory is unusual.
The technological process simulator 10 of Fig. 1 is to be equivalent to parameter correcting device 101, technological process emulation mechanism 102 and realistic model 103.
Though compared with the running of machinery or electronic system, the running of technological process that is attended by microbial reaction or chemical reaction is extremely complicated especially, yet some technological process simulator is initiatively to use physics or chemical model.Even these models are also imperfect, yet it still can provide the entity plant data to these simulators, some parameter that compensates these models and the factory of emulation satisfactorily.
In technological process simulator 10 of the present invention, realistic model 103 is to represent with physics or chemical model.Therefore, this model can handle or manifest not only that for example those can't install the temperature in inductor place and the entity information of flow velocity in entity factory, and also can handle or manifest that for example those can't actual measurement or information such as observed relative scale and boiling point.
In addition, the present invention can make technological process emulation mechanism 102 turn round with the speed that is higher than factory running, and can obtain anticipation trend before several minutes of present time or a few hours, so that the operator of factory can utilize these anticipation trends to do factory's control.And the present invention can will pass by the result of emulation for the purpose of factory diagnosis and compare with the result of present emulation, so that reach the maintenance part that early detection factory changes filtrator for example etc. unusually or in real time.
The control of factory can be watched the picture of anticipation trend and manual operation via the operator of factory, but also can be automatically performed by control part 111.
If for example, when technological process emulation mechanism 102 and future anticipation device 109 were positioned on the same computing machine, when future anticipation device 109 was carried out emulation with high speed, technological process emulation mechanism 102 just can stop emulation, so that reduce the load of CPUs.
If the system of parameters of a realistic model is revised according to known experimental knowledge, then do not need parameter determination device 105.
If computing machine has the arithmetic capability of height, the calculated off-line of parameter determination device 105 just can onlinely be carried out, and in other words, promptly is when factory's actual operation.
Then, will the display device of plant operation support system of the present invention be described.The example of the several conventional display device of at first first cutline.
Fig. 3 illustrates a typical process process trend picture that uses traditionally.
This picture can show the time series data that is placed on the inductor in the factory as trend data or historical data, so that the situation such as unusual that takes place in the monitoring factory.
Yet these conventional plant operation support systems also can't provide the on-line prediction of plant operation state.
Fig. 4 illustrates an example of plant operation support system display device picture of the present invention.Transverse axis is a time shaft, indicates over, now and future, and the longitudinal axis then shows 0 to 100 number percent.This example demonstrates present time (g) at middle position, and more preceding to the time just over 10:14:00 from 10:10:00 indicated by time shaft system.In Fig. 4, curve (a) shows the actual measurement data from the technological process output data of entity factory 30, and curve (b) shows the emulated data from the emulation output of technological process emulation mechanism 102 among Fig. 2.This emulated data shows the Temperature Distribution in a reactor for example or the time series data of the physical constant of product in this reactor.
Curve (c) is the output from future anticipation device 109, and demonstration starts from 10:11:00 and lasts till the 10:14:00 prediction of any later.The demonstration of this curve is to start from a special time to a fixed time or with the prediction emulation of an interval mode when the mode of an operator by a display device picture etc.When assigning prediction emulation and start indication, factory's simulator 10 (referring to Fig. 1) just uses a simulation state amount, and carries out in advance emulation to one fixed time before the real time, and in a display frame display result.
In Fig. 4, if show the input media that utilizes mouse for example on the trend chart of actual measurement data, emulated data and predicted data and specify a magnification region one, the zone that desire is amplified specifies the magnification region indicator to be presented by one, and should amplify in the zone.
Fig. 5 illustrates a trend chart, and wherein the zone of (d) among Fig. 4 is exaggerated via an enlarging function.This picture demonstrates a prediction emulation and starts, and demonstrates one and present the indicator of start-up time, and demonstrates between at that time and begin to be written to the time series trend chart of a fixed time.
Anticipation trend figure is updated to last state forever.Last anticipation trend figure then deletes from picture.
This amplification picture not only demonstrates the figure of amplification, demonstrate more simultaneously between a designation area in or for example in the statistics of distributed data, the difference between actual measurement data and the emulated data.
Get back to Fig. 4, arrow (e) shows a prediction caution display packing.In this display device,, just can produce a prediction caution if the time series data of prediction surpasses predetermined tolerable value.Afterwards, produce marking device once the prediction caution and be presented on the anticipation trend figure, and also indicate in future anticipation caution summary to estimate to produce constantly.
Fig. 6 illustrates an example of future anticipation caution summary, different colours or predictive marker is wherein arranged to distinguish prediction caution and actual caution.In the example of Fig. 6, ● the expression caution is resulted from over, and zero expression is the caution of prediction.It should be noted that if avoided the prediction caution because of the factor of the change or the like of operation, the prediction caution just can be deleted automatically.
According to the display device of carrying out above-mentioned demonstration, wherein in the factory demonstration of the future anticipation trend of parameter provided than tradition more Useful Information to the operator.Therefore unusual and prevention quality descends more effective for the early detection of factory.In addition, future anticipation can determine whether now the plant operation state is to be in optimal cases.
It should be noted that particular suitable embodiment pointed in the above stated specification is only for explaining orally the present invention and usefulness for example.For example, this embodiment one of them be to demonstrate one to follow the trail of according to the parameter of being used as the future anticipation function and to have factory's simulator of strengthening accuracy.Yet it can also be the forecast function of a use mathematical model.And, future anticipation trend picture also can another different windows show go to one the prediction start-up time trend data.
In addition, the time series data of prediction, actual measurement data, emulated data or the like all can different colours or the lines form present.
Therefore, the present invention is not limited in the foregoing description, but under the situation that does not deviate from essence of the present invention, for the various changes of previous embodiment or revise all belong to feasible.
