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.
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.
