And a data integration means.

  ADVANTAGE OF THE INVENTION According to this invention, the plant model development system which can perform a plant model development can be provided, without an operator being conscious of the change location of an equipment model and a plant model, and the influence by change.

(First embodiment)
FIG. 1 is a configuration diagram of a plant model development system according to the first embodiment of the present invention. In the first embodiment, a data management means 12 for managing a manufactured model and a history of simulation results is added to the conventional example shown in FIG. The same elements as those in FIG. 13 are denoted by the same reference numerals, and redundant description is omitted.

  The data management unit 12 includes a history DB 2B, a change data extraction unit 13, and a data integration unit 11. The history DB 2B includes a history management means 25, a plant model (history DB) 3B, a device model (history DB) 4B, and a simulation result (history DB) 9B. Moreover, the change data extraction means 13 has the extracted change data.

  For example, the worker performs the creation work of the equipment model 4A and the plant model 3A by the equipment model creation means 23 and the plant model creation means 24 in the work DB 2A. When a certain work is completed, the worker performs a confirmation process on the created or changed model with respect to the plant model development system. As a result, the plant model development system has a mechanism for assigning a revision number to the model and registering the model in the history DB 2B.

  The change data extraction means 13 compares the models 3A and 4A of the history DB 2B and the models 3B and 4B of the work DB 2A during the work DB2A determination process, extracts the change data 14, and if there is the change data 14, the model Number the revision. As described above, the change data extraction unit 13 has a function of creating the change data 14 and a function of assigning a revision number.

  The simulation result 9A executed by the execution control means 7 is also associated with the management numbers of the plant model 3A and the equipment model 4A and registered in the history DB 2B. Further, the registered simulation result 9B is managed by the history management means 25 as evidence of a plant model unit test for each plant model 3B.

  FIG. 2 is a flowchart showing the processing procedure of the change data extraction means 13. First, when the process is started, the change data extraction unit 13 extracts an update file (step S1), and after extracting the update file, performs a comparison process of the device model 4A (B) (step S2), and changes before and after the update. Detection is performed (step S3). When a change is detected, the revision number is updated for the device model 4A, and the management number for managing the elements constituting the device model 4A is updated. Furthermore, the device model change information 4C describing the change information of the device model 4A is also output (step S4).

  Similarly, a plant model comparison process is performed for the plant model 3A (step S5), followed by change detection (step S6). If a change is detected, the revision number for the plant model 3A is detected. Update, update of the management number for managing the elements constituting the plant model 3A, and output of the plant model change information 3C describing the change information of the plant model 3A (step S7). The change data 14 is created by integrating the device model change information 4C and the plant model change information 3C output last (step 8).

The constituent elements of the device model 4A are graphic information 4A1, source code 4A2, and input / output information 4A3, and revision numbers are assigned to the respective constituent elements. Examples of components of the plant model 3A include a plant model figure 3A1, plant equipment configuration information 3A3 for managing the construction information of the equipment model 4A arranged in the plant model figure 3A1, and a set value list 3A2 set for the model. And plant model management information 3A4 for managing them.

  Here, if a change is made to the source code 4A2 constituting the equipment model 4A of FIG. 3, the revision number of the source code 4A2 is updated, and then the management number of the equipment model management information 4A4, the plant equipment configuration information The contents of 3A3, the management number of plant equipment configuration information 3A3, the contents of plant model management information 3A4, and the management number of plant model management information 3A4 are updated in this order. In the history DB 2B of FIG. 1, not only the model history but also the device model management information and the plant model management information are registered by the history management means 25.

  Further, the management number of the plant model management information 3A4 is associated with the simulation result 9A, so that it can be easily determined which model the simulation result 9A was created with. By referring to the change data 14 obtained by the change data extraction means 13, the worker can grasp changes by other workers and can study the influence of the change.

  Moreover, the simulation result 9A and the simulation result 9B registered in the history DB 2B and the change data 14 are integrated by the data integration means 11 of FIG. 1 and displayed simultaneously, thereby easily comparing the difference in the simulation result due to the change. Is possible.

  According to the first embodiment of the present invention, the equipment model, the plant model, and the simulation result are managed, and the worker can change the equipment model and the plant model by accurately grasping the change management and the influence of the change. The plant model can be developed without being conscious of the influence of the location and the change, and the development efficiency of the plant model can be improved.

(Second Embodiment)
FIG. 4 is a configuration diagram of a plant model development system according to the second embodiment of the present invention. In the second embodiment, an influence range extraction means 15, an influence range display means 16 and a plant model source automatic output means 26 are added to the first embodiment shown in FIG. is there. The same elements as those in FIG.

  The influence range extraction unit 15 extracts an influence range due to the change based on the change data 14 obtained by the change data extraction unit 13. The influence range display means 16 displays the plant model 3A that needs to be re-output when it is necessary to re-output the plant model source 6 within the influence range. Further, the plant model source automatic output means 26 automatically performs re-output of the plant model source 6 in response to a request from an operator.

  FIG. 5 is a relationship diagram between the plant model 3A and the equipment model 4A. As shown in FIG. 5, one plant model 3A is composed of two or more device models 4A. If the number of plant models 3A is enormous, the relationship with the device model 4A is enormous. Here, if a change occurs in a certain equipment model 4A, the influence affects a large number of plant models 3A using the equipment model 4A, and the plant model source 6 that is within the influence range as necessary. Must be output again by the plant model output means 5.

  Therefore, the influence range extraction unit 15 extracts the plant model 3A that requires re-output of the plant model source 6 using the change data 14 obtained by the change data extraction unit 13, and the influence range display unit 16 uses the influence range display unit 16. Is displayed and clearly shown to the operator. Furthermore, the plant model source automatic output means 26 automatically outputs the plant model source 6 again in response to a request from the operator to the plant model development system.

  FIG. 6 is a flowchart showing the processing contents of the influence range extraction means 15. The influence range extracting means 15 determines whether or not there is a device model 4A that has been changed (step SS1). If there is a device model 4A that has been changed, the contents of the change data 14 are analyzed (step SS2). Then, it is determined whether an adjacent device model connected to the device model 4A is affected (step SS3). If there is an effect, the device model is corrected (step SS4).

  Next, when it is determined in step SS1 that there is no changed device model, it is determined whether there is a plant model having a change with respect to the plant model (step SS5). If there is a changed plant model, the contents of the changed data 14 are analyzed (step SS6), and it is determined whether the plant model source 6 is affected (step SS7). By performing this process for all plant models 3A, the influence range extraction process is completed.

  According to the second embodiment of the present invention, it is not necessary for the operator to re-output the plant model source 6 within the range of influence by the change, and only necessary portions can be performed without omission. Become.

(Third embodiment)
FIG. 7 is a configuration diagram of a plant model development system according to the third embodiment of the present invention. In the third embodiment, an influence range extraction means 15 and an influence range display means 16 are additionally provided to the first embodiment shown in FIG. When the influence range due to the partial change is extracted and it is determined that the equipment model 4A connected to the equipment model 4A has an influence, the influence range display means 16 displays the equipment on the production screen for creating the plant model 3A. All the influence ranges due to the change of the model 4A are displayed, and the contents to be corrected of the connected device model 4A are provided. The same elements as those in FIG.

  In FIG. 7, the output of the influence range obtained by the influence range display means 16 is displayed on the production screen (plant model production screen) of the plant model 3A. Then, the contents to be corrected of the connected device model 4A are provided.

  FIG. 8 is an explanatory diagram of an example of displaying the influence range on the plant model production screen. In FIG. 8, if the input / output information (point A) of a certain device model X is changed, the changed data is input to the influence range extracting means 15. The influence range extracting means 15 determines whether or not there is an influence on the equipment model 4A (adjacent equipment model) connected on the equipment model X and the plant model, and it is judged that the connected equipment model is affected by the change. Then, all the plant models 3A in which the equipment model X is used are extracted.

  Then, the influence range display means 16 highlights the plant model 3A on the influence range display screen (plant summary) 18. The operator can expand the screen on the plant model production screen 19 by selecting the plant model 3A to be confirmed with a mouse or the like. The plant model production screen 19 displays all the influence ranges due to the change of point A, and by selecting point A with a mouse or the like, the change contents of point A and the contents to be corrected of the adjacent device model are displayed. It is possible to provide.

  According to the third embodiment of the present invention, the influence on the adjacent device model due to the change of a certain device model becomes clear, and the adjacent device model can be easily corrected.

(Fourth embodiment)
FIG. 9 is a plan view of a plant model production screen for explaining the function of the device model automatic adjustment means of the plant model development system according to the fourth embodiment of the present invention. This fourth embodiment is different from the third embodiment in that there is a mismatch in input / output information between two device models connected on the production screen for creating a plant model. Automatic adjustment means for automatically arranging and connecting conversion parts that can be absorbed and can be matched with the plant model is provided.

  9, FIG. 9A shows a plant model production screen before the connection of the device model 4A, and FIG. 9B shows a plant model production screen after the connection of the device model 4A. As shown in FIG. 9B, after the connection of the device model 4A, a conversion component 20 for connecting the device model 4A is automatically created.

  Now, consider a case where an operator connects two device models 4A (for example, a pump and a valve). The device model 4A has input / output information 4A3 that defines the input / output contents of the device, and the connected device model 4A needs to satisfy the conditions of the connection rule in which the mutual input / output information 4A3 is consistent. It is.

  As shown in FIG. 9A, in the plant model production screen (before connection) 19, the unit of the component concentration which is a part of the input / output information 4A3 on the pump outlet side does not match the unit of the component concentration on the valve inlet side. There is. In such a case, in the conventional system, it is necessary to unify the unit on the valve side and the unit on the pump side. Therefore, for example, it is conceivable to change the unit on the valve inlet side to mol / l. In such a case, the unit on the valve side and the unit on the pump side coincide with each other, but there is a possibility that the other equipment model 4A connected to the valve inlet side may be affected, so that it cannot be easily changed. Further, in an actual plant such as a reprocessing plant, the units used may differ for each facility and process, and it is not easy to unify the units in the plant model 3A that performs simulation. As a result, although the characteristics of the device model 4A are the same, a derivative device model in which only the units are different has to be manufactured.

  On the other hand, in the plant model production screen (after connection) 19 in FIG. 9B, when connection is performed in a state having such a mismatch, the conversion that can absorb the mismatch and take the consistency of the plant model is possible. It has a function (automatic adjustment means) for automatically generating and arranging and connecting the parts 20. The automatic adjustment means generates an appropriate conversion component 20 based on the contents of the conversion DB 21 when the connection is made in a state of inconsistency.

  According to the fourth embodiment of the present invention, the operator can easily create a plant model without being aware of the mismatch of the input / output information 4A3 such as the unit, and can also create only the unit. However, it is unnecessary to produce redundant derivative equipment models with different values.

(Fifth embodiment)
FIG. 10 is a configuration diagram of a plant model development system according to the fifth embodiment of the present invention. This fifth embodiment is different from the fourth embodiment in that it includes an influence range automatic correction means 22 that extracts an influence range due to a partial change of the device model 4A and automatically corrects the influence range. The automatic correction means 22 is configured to automatically correct the plant model by the conversion component 20 when it is determined that other device models connected to the device model 4A are affected.

  When the device model 4A is changed, the influence range automatic correction unit 22 extracts the influence range by the influence range extraction unit 15 and automatically corrects the plant model 3A in the influence range.

  FIG. 11 is a plan view of a plant model production screen for explaining the function of the influence range automatic correction means 22 of the plant model development system according to the fifth embodiment of the present invention. FIG. 11A shows a plant model production screen before connection of the device model 4A, and FIG. 11B shows a plant model production screen after connection of the device model 4A.

  As shown in FIG. 11A, in the plant model production screen (before unit change) 19, the input / output information 4A3 of the two device models 4A is not inconsistent against the connection rule, and represents the connected state. Yes. As shown in FIG. 11B, the plant model production screen (after unit change) 19 represents a state where the unit of the component concentration at the pump outlet is changed from mol / l to g / l.

  When this change is made, it is determined that the unit on the valve inlet side needs to be changed by the influence range extraction means 15, and the influence range automatic correction means 22 is requested by an operator requesting the system. The plant model 3A is automatically corrected by automatically generating, arranging and connecting the conversion parts 20 by the method described in the fourth embodiment.

  According to the fifth embodiment of the present invention, since the influence range automatic correction means 22 is provided with the function of generating the conversion component 20, the influence due to the change of the device model 4A can be reduced.

(Sixth embodiment)
FIG. 12 is a block diagram of a plant model development system according to the sixth embodiment of the present invention. The fifth embodiment is different from the second embodiment shown in FIG. 4 in that an influence range automatic correction means 22 and an automatic test means 27 are provided. The same elements as those in FIG. 4 are denoted by the same reference numerals, and redundant description is omitted.

  The automatic test means 27 automatically and continuously executes the plant model source 6 re-output by the plant model source automatic output means 26 using the execution control means 7 at the request of the operator.

  The simulation result 9B is stored and managed in the history DB 2B by the history management means 25 as evidence of a unit test of the plant model 3B for each plant model 3B. In this case, when the equipment model 4A and the plant model 3A are changed, the influence range must be extracted and the plant model within the influence range must be retested. Re-testing the plant model is very inefficient.

  Therefore, the automatic test means 27 executes all the plant model sources 6 that have been re-outputted by the plant model source automatic output means 26 continuously at the request of the operator and retests them. The influence range automatic correction means 22 is the same as that described in the fifth embodiment.

  According to the sixth embodiment, it is not necessary to manually test individual plant models 3A that are affected by the change, so that work efficiency can be improved.
