Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block diagram analysis for performing dynamic characteristic simulation of various plants such as a boiler using a block diagram, and more particularly to a block line which can be commonly used for analysis of various operation objects. The present invention relates to a block diagram analysis suitable for performing a simulation of a system such as a large-scale plant using a calculation model represented by a diagram.

[0002]

2. Description of the Related Art In a large-scale system such as a plant, when simulating a dynamic characteristic of a system or a control system, a symbol (hereinafter referred to as "operation") indicating an operator for performing operations such as integration and proportion as shown in FIG. A block diagram composed of lines indicating signal lines (hereinafter referred to as signal lines) for transferring data between operators and operators (hereinafter, a program for creating the block diagram is referred to as a block line). A method of simulating with a computer based on this block diagram is often used. This means that if the calculation model is represented in the form of a block diagram,
This is because it is easy to understand what kind of calculation is performed by following the operator that defines the operation content and the signal order that defines the operation order of multiple operators and the transfer of operation data.
For example, it is realized by a software configuration as shown in FIG. That is, a block diagram is created by the block diagram creating section 91, the created block diagram is displayed on the display 12 by the block diagram display section 96, and the block diagram editor is executed based on the created block diagram. Block diagram data is created, and the created block diagram data 92
In the simulation program 61 by the data conversion unit 93
Is converted into an input data format (simulation data 94), and the converted simulation data 94 is used as an input for calculation by the simulation program 61, and the result is represented by a trend graph 95.

In the block diagram, a signal input from a signal line to an operator terminal is operated in the operator, and the result is output from another terminal of the operator to the signal line. In addition,
Hereinafter, the end of the signal line with the arrow is referred to as the end point, and the end without the arrow is referred to as the start point. That is, the signal is passed from the operator on the start point side to the operator on the end point side of the signal line.

The arrangement of the operators and the wiring of the signal lines are realized by, for example, a method shown in FIG. FIG. 39 shows a display screen of the block diagram creation system, which is composed of a block diagram area 120 where operator 101 and signal line 102 are arranged and wired, and a list 121 of operators. The user designates an operator in the operator list 121 with the mouse cursor 100, and then designates the position to be arranged in the block diagram area 120 with the mouse cursor 100, and designates the position in the operator list at that position. Operator is displayed.
By repeating this operation, the operator can be arranged in the block diagram area 120. The signal lines connect the terminals 123 of the operators, and the terminals of one operator are designated by a mouse cursor, and the terminals of the other operators are designated by a mouse, so that the signal lines can be wired. it can.

The block diagram data is composed of operator data and signal line data. When an operator and a connection line are created, numbers that are not duplicated within the computer are given, and are managed by the numbers thereafter. . As shown in FIGS. 40A and 40B, an operator number and a signal line number are set for the operator and the signal line, respectively.

[0006] As shown in FIG. 40A, the operator data includes two-dimensional coordinate values of X and Y when displayed on the screen, and terminals, in addition to the operator number and the content of the operation. Contains the number of the signal line. Further, there is a parameter area for setting parameters required for the operation, such as a constant value if the operation is an operator having a constant value, and a constant value if the operator performs a proportional operation.

In the signal line data, as shown in FIG. 40B, a signal line number, a name of the signal line, coordinates for display, and an operator number connected to the start point and the end point are set. Have been. 40 (a) and FIG. 40 (b)
In both figures, the coordinate column is blank, but actually contains two-dimensional X and Y coordinate values when displayed on the screen.

In order to represent a block diagram having a large number of operators that cannot be included in one block diagram area,
There is a method in which a part of one block diagram area is regarded as one page, and one block diagram is represented using a plurality of pages, such as page 1 and page 2 in FIG. For this purpose, as shown in FIG. 40 (c), page data for distinguishing operators and signal lines belonging to each page is required. That is, an operator number and a signal line number belonging to the page are set as page data.

In FIG. 39, the SIN operator and the COS
Although some of the operators are displayed in an overlapped manner, this can be achieved by setting the display condition to “when the display is overlapped, the one drawn later is preferentially displayed for the overlapped portion”. In other words, in this case, the SIN operator is drawn first, and the COS operator is drawn later, and the COS operator is displayed in a portion where the two overlap.
However, in the prior art, the two are merely close in coordinates, and there is no data linking the two in the data (operator data, signal line data, etc.) of the block diagram.

The block diagram data is supplied to a data converter 93.
Is converted into simulation data as shown in FIG. This simulation data is composed of data of one operator per line. In one row, the signal line name (BB) of the signal line input to the operator, the operator name (SIN), the signal line name (CC) of the signal line output from the operator, and the operator are used for the operation. It consists of parameter values (3.4.). Here, the contents in parentheses indicate the case of the third line in FIG.

It has been described that the signal input from the signal line to the input terminal of the operator is operated in the operator and the result is output to the signal line from another terminal (output terminal). Signals are exchanged between pages using operators of input and output. In other words, to pass a signal from one page to another page, connect a signal line to the output operator at the end of the output page, and connect the signal to the input operator on the other page (input page). The signal is passed from the input operator to another operator in the same page using a signal line. Signals are passed from the output operator to the input operator without using a signal line because the page is different, and the operator number of the partner is set as a parameter of the operator. Hand over.

In the case of a complicated mechanical system or control system such as a boiler, it is so complicated that a large-scale block diagram combining thousands of operators must be created. Although it is easy to understand by representing the calculation model with a block diagram,
When combining thousands of operators, it is necessary to devise ways to make them even easier to understand. For example, if the entire block diagram consisting of thousands of operators is displayed on the display as it is, each operator or signal line is displayed small and too fine, making it difficult to arrange operators and wire signal lines. Therefore, pages are divided into several tens to hundreds of operators, and each page is displayed on the display. Operators and signal lines are displayed in a certain size to facilitate placement and wiring. Is to be able to That is, by dividing a complicated block diagram into pages, an easy-to-understand block diagram can be created. In this case, if the block diagram for one page is expressed by one operator (page operator), a complicated block diagram can be easily expressed by connecting the page operators with signal lines. it can.

By using page operators, for example, as described in Japanese Patent Application No. 5-41436, a block diagram composed of thousands of operators is divided into groups including tens to hundreds of operators. As shown in FIG. 35, a page operator can be arranged in a page in the same manner as other operators, using a page operator in which one page is represented by one operator. In this case, a method of layering the block diagram to make it easier to understand is also used. here,
From the viewpoint of the page operator, the corresponding page is called a corresponding page, and conversely, the corresponding page operator as viewed from the page is called a corresponding page operator. When the page operator is used, FIG.
(A) shows the general signal flow, and (b) shows the corresponding detailed block diagram.

The page operator and the corresponding page are simply divided into layers to make the complicated block diagram easier to understand, but are made easier to understand by associating the divided pages with plant equipment. . For example, as shown in Japanese Patent Application No. 8-10839, the calculation model of the heat exchanger shown in FIG. 36 is represented as a corresponding page in a block diagram, and a plurality of page operators corresponding to the page are arranged, whereby heat exchange of the boiler is performed. A method is also used to represent the flow, that is, the heat flow from the superheater to the reheater and further to the economizer. In other words, the page operator can correspond to the boiler equipment such as superheater and reheater. By positioning the page operator as a module representing the boiler equipment, the correspondence between the block diagram and the actual equipment Is easy to understand.

The operator data includes (a) in FIG.
As shown in the above, in addition to the calculation contents, the coordinate values for display, the number of the connected signal line, the parameters required for the calculation (for example, a constant value for a constant value operator, a proportional constant for a proportional operator) ) To set the parameter area,
For the page operator, the page number of the corresponding page is set as a parameter.

The signal input to the operator from the signal line is operated in the operator, and the result is output from the signal line as described above. However, between the page operator and the corresponding page, Signals are transmitted and received using operators such as input, output and output. This is the same as the above-described case of transmitting and receiving a signal between pages. That is, a signal input to the page operator is connected to an operator of input of the corresponding page, and a signal from the operator of output of the corresponding page is a signal output from the corresponding page operator.

[0017]

A block diagram of a complicated mechanical system and a control system such as a boiler is created by repeating trial and error. In other words, if the calculation of the operator and its parameters seems to be bad, the operator and the parameters are changed and the calculation is performed again. I recalculated it, but sometimes the result was not so good and I changed it back.
In other words, there are times when you want to keep both before and after the change. In addition, although the calculation could be done somehow, the calculation may be repeated again by changing the operator and the parameter because it is not satisfactory. Also in this case, since it is not known whether the calculation of the second time is satisfactory or not, there is a case where it is desired to keep the changed state in the middle so that the original state can be returned at any time. However, with the conventional block diagram creation system, the created block diagram is directly converted into simulation data.When changing operators and signal lines, delete the operators and signal lines before the change and then add a new one. It is necessary to arrange and wire the changed operators and signal lines. In other words, in the state after the change, only the changed block diagram is present, and the operator and signal lines before the change are not displayed, but are also deleted from the data of the block diagram. The previous block diagram no longer exists. Therefore, it is difficult to restore the changed block diagram. In other words, in order to return to the original state, it is necessary to delete the operator and signal line after the change, and then newly arrange and wire the operator and signal line before the change. In addition, since the data before the change and the data after the change are not described together, it is unknown how the data was reached,
The simulation data is not easy to understand.

For example, JP-A-57-134752 discloses an asterisk (*) beside a display operator after a change.
) Is displayed so that the user can easily understand the change, but it is not considered that the changed operator is returned to the state before the change, and there is no means for that. When an operator is deleted, the operator data is also deleted, so it is difficult to undo the change, which is a typical conventional example.

Further, as described above, the hierarchization of the block diagram and the use of the equipment modules have the effect of making the block diagram easier to understand. However, for example, superheaters, reheaters, and economizers are all heat exchangers and their block diagrams are almost the same, but the difference in the conditions of the heat exchange medium and the difference in the structure as equipment Because of this, the block diagrams cannot be exactly the same, and the parameters of the operators are different and the contents of calculations are slightly different. Therefore, it is necessary to separately represent the different parts with a block diagram. As shown in FIG. 37, the block diagram of the original heat exchanger is first copied for each heat exchanger,
Next, the copied block diagram needs to be modified for each heat exchanger. In the example of FIG. 37, since the superheater can use the heat exchange module as it is, it is not necessary to modify the block diagram and the parameters. In contrast, the reheater has modified the parameter of the proportional operator 106 from 1 to 2. In addition, the economizer has an integral operator 107 added after the proportional operator 106 (FIG. 37 is an illustrative example, and is a block diagram of the actual superheater, reheater, and economizer). is not). In other words, the superheater, reheater and economizer are all conceptually heat exchangers, but there are small differences in actual equipment, so a block diagram dedicated to each heat exchanger is required. Can not be shared by two block diagrams or modules, the block diagram becomes complicated,
There is a problem that the common part and the corrected part are difficult to understand, and as a result, the block diagram is difficult to understand.

In addition, the created block diagram may be changed in order to correct a defect or to increase the accuracy of calculation. In this case, if a common part is changed in each heat exchanger, the changed Need to be similarly modified. In other words, similar corrections must be made to all of the copied block diagrams relating to the heat exchanger, so that there is a problem that the correction is troublesome and it is difficult to determine whether or not all the corrections have been made.

A first object of the present invention is to make it possible to easily return a once changed block diagram to a state before the change. A second object of the present invention is to make a complicated block diagram easy to understand and to easily correct a common part of a modularized block diagram.

[0022]

The first problem is that when an operator or a signal line is changed, the operator or signal line before the change is deleted instead of deleting the block diagram that is the source of the change. This can be achieved by leaving the data as it is and newly creating the operator of the changed part and the data of the signal line. The newly created operator and signal line are displayed so as to overlap the operator and signal line before the change, and the newly created operator and signal line are displayed with priority. Further, when converting the block diagram having the operator and signal lines before and after the change into the simulation data, the operator before change and the signal line data are invalidated, and the newly created operator and the changed operator are used. The signal line data is converted into simulation data so as to be valid. Conversely, prior to displaying the operator and signal line before the change, when converting to simulation data, enable the operator and signal line before the change, and disable the operator and signal line after the change. Can solve these problems.

When the above means is used, the block diagram after the change can be created while leaving the block diagram before the change, so that the difference between the block diagrams before and after the change can be displayed in an easy-to-understand manner. Further, not only the simulation data after the change, but also the block diagram before the change can be returned, and the block diagram before the change can be converted into the simulation data, so that the trial and error of the block diagram can be easily performed. . As a result, data creation time can be reduced,
Simulation efficiency can be improved.

The second problem is that when changing parameters and calculation contents, instead of changing the original block diagram, operators and signal line data of the changed portions are newly created and created. This can be achieved by providing information and, in the case of deletion, the deletion information in the data of the page operator.

When the above means is used, only the data of the deleted or added operators and signal lines is newly created for each page operator from the original block diagram. There is no need to copy the original block diagram for each child, and only one original block diagram is required. In addition, the changed part and the original part can be considered separately, and the movements and differences of the respective device models can be represented in an easy-to-understand manner, so that an easy-to-understand block diagram can be created. Furthermore, when correcting a common part of each device module, only the original block diagram needs to be corrected, so that it can be easily corrected, and it is not necessary to check whether all modules have been corrected.

As described above, by creating a module that can be used in common, a block diagram can be displayed in an easily understandable manner, data creation time can be shortened, and simulation can be made more efficient.

In the present invention, the block diagram of the corresponding page itself is not modified or changed in order to easily create a page operator having a slightly different function. Only, in order to make the block diagram of the corresponding page appear to be modified and changed, the modifications and changes are stored in the page operator. In short, the feature of the present invention lies in that the block diagram of the lower hierarchy can be modified and changed when the block diagram of the lower hierarchy is viewed from the operator of the upper hierarchy. On the other hand, similarly to the present invention, as well-known examples of hierarchically creating a block diagram and storing information between layers, JP-A-6-76012, JP-A-7-271840, and 62-51450 and JP-A-1-502
621 publication. JP-A-6-76012 discloses that
Japanese Patent Application Laid-Open No. Hei 7-271840 discloses that a lower page is added with a development history and reference information between layers in order to easily display the positional relationship of the layers between the upper page and the lower page. To facilitate the connection of the diagram,
One that saves the connection information of the page operator in the upper page and displays it when the lower page is expanded.
In order to facilitate the work of expanding from a functional logic diagram to a detailed logic diagram, the functional logic operators (Jpn.
In Japanese Patent Application Laid-Open No. 1-502621, the relationship between parts and information on parts in a hierarchical structure diagram of a product are displayed in an easily understandable manner. For this purpose, text data and graphic file names related to parts are associated with parts in the structural diagram. In short, these applications relate to a technique for making the relationship between hierarchies easy to understand, and do not relate to a concept or a method of modifying or changing a block diagram of a lower hierarchy, which is a feature of the present invention.

[Embodiment 1] The first embodiment of the present invention will be described below.
Will be described with reference to the drawings.

(I) Overall Configuration FIG. 1 shows a specific configuration of this embodiment. The illustrated device includes a computer main body 11, a display 12, a mouse 13, and a keyboard 14 connected to the computer main body 11, and the computer main body 11 includes a block diagram creating section 15,
It is configured to include a block diagram display unit 17, block diagram data 16, and a data conversion unit 18. The simulation data 19 is created by converting the block diagram data 16 by the data conversion unit 18. The block diagram creation unit 15 includes a lower operator number setting unit 23, an upper operator number setting unit 24, an operator coordinate determination unit 22, and an upper / lower operator conversion unit that switches the upper and lower operators of the overlapping operator. There are 25. The operator data in the block diagram data 16 includes a lower operator number setting area 20 and a higher operator number setting area 21. The upper operator number setting section 24 of the block diagram creating section 15 and the lower operator The operator number is set by the number setting unit 23. Further, in the block diagram display section 17, there are a lower operator non-display section 26 for stopping the display of the overlapping lower operators, and an overlapping operator display section 27 for displaying the overlapping. The data converter 18 includes
A low-order operator data non-conversion unit 28 for stopping conversion of overlapping low-order operator data is included.

(Ii) Interaction and operation of each component When changing an operator to another operator, the conventional operator deletes the operator before the change and newly places the operator after the change. In the present embodiment, a new operator is left over without being deleted, and a new operator is arranged thereon to display the new operator preferentially, and data indicating an overlap with the operator data can be registered. . Furthermore, when converting the created block diagram into simulation data, of the operators displayed in a superimposed manner, only the displayed operators are converted,
Hidden behind the displayed operator, operators not displayed are not converted. In addition, in the case of two or more displayed operators, the displayed operator and the operator hidden behind are interchanged, so that the overlap can be changed.

FIG. 2A shows the operator data of the block diagram of the present embodiment. Compared to the conventional operator data (FIG. 40A), the area 20 for setting the lower operator number and the upper An area 21 for setting an operator number has been added.
When operator data is created, 0 (zero) is set in the regions 20 and 21 in the sense that there is no overlap of operators. However, when operators are overlapped according to the present invention, overlapping operations are performed. The child operator number is set. FIG. 3 is a display example of a block diagram. FIG. 3A shows a block diagram without any overlap as it is. FIG. 3B shows FIG.
(A) above the SIN operator 103 and the COS operator 10
4 shows a state in the middle of stacking. FIG. 3C shows S
The state where the COS operator 104 is overlaid on the IN operator 103 is shown. In this state, the SIN operator is hidden below the COS operator 104. FIG.
SIN hidden under the COS operator 104 in (c) of FIG.
The operator 103 is displayed in a table, and the COS operator 104 displayed in FIG. 3C is hidden behind the SIN operator 103.

This embodiment is realized by the components 20 to 28 in FIG. The specific movement will be described with reference to FIG.
First, the user operates the mouse 13 and the keyboard 14 by using the block diagram creation unit 15 in FIG.
Create a block diagram shown in The created block diagram becomes block diagram data 16 shown in FIG.
The created block diagram data 16 is displayed on the display 12 by the block diagram display unit 17. When this block diagram data 16 is converted into simulation data, the result is shown in FIG. Up to this point, the above-described prior art has been described.

Hereinafter, according to the present invention, the SI in the block diagram will be described.
A procedure for newly overlaying the COS operator on the N operator 103 will be described. COS from operator list by mouse cursor
Select an operator. Next, the mouse cursor is moved close to the SIN operator 103, and a new COS104 operator is superimposed on the SIN operator 103. At this time, the coordinate determination unit 22 compares the display coordinates of the new operator with the display coordinates of the operator already displayed, and determines whether the SIN operator 103 satisfies a certain determination condition. For example, SIN where the display coordinates of the new COS operator 104 change
At or near the display coordinates of operator 103, CO
When the S operator 104 is displayed so as to overlap the whole or a part of the new operator 103, it may be determined that the SIN operator 103 is changed to the COS operator 104. This determination is realized, for example, as follows. When the new COS operator 104 is arranged, the X coordinate value of the COS operator 104 is Xcos and the Y coordinate value is Ycos. These coordinate values are compared with the coordinate values of other operators in the operator data. For example, the X coordinate value of a certain operator in the operator data is X0, the Y coordinate value is Y0, and the display operation is performed. Assuming that the size of the child is V in the vertical and H in the horizontal, the value of Xcos is X0− (1 /
2) XH or more and X0 + (1/2) × H or less, and Yco
When the value of s is Y0- (1/2) × V or more, Y0 + (1/2)
If xV or less, a certain operator and a new COS operator 10
It is determined that 4 overlaps. In other words, here SIN
It is assumed that the operator 103 satisfies this determination condition. Here, the numerical value of (1/2) is an example, and another numerical value (for example, 1/4) may be used as long as it is 1 or less. By using the mouse cursor to designate the SIN operator 103 in advance without using the coordinate determination unit 28, for example,
The operator before the change (the lower operator to be superimposed) may be specified.

Next, conventionally, when a new operator is arranged, the operator data of the new operator (CCOS operator 104) is merely created as the operator number 7, but in this embodiment, the new operation is performed. If a child appears over an existing operator and decides to change to a new operator,
In addition to newly creating the operator data of the COS operator 104 as the operator number 7, the operator number (that is, 3) of the operator underneath (that is, the SIN operator 103: the operator number 3) is The data of the newly added COS operator (operator number 7) is set in the lower operator number setting area 20. At the same time, the SIN under the COS operator 104
The operator number (i.e., 7) of the operator (i.e., the COS operator 104) that is superimposed thereon is set in the upper operator number setting area 21 of the operator data of the operator 103. CO
The operator data after setting the S operator 104 is shown in FIG.

Next, the display on the display 12 will be described. The lower SIN operator 103 is not displayed because the lower operator non-display unit 26 detects that a numerical value other than 0 is set in the upper operator number setting area 21 of the operator data. Further, in order to explicitly indicate the overlap, the overlap operator display unit 27 displays the COS
The SIN operator 103 on the back side of the operator is slightly shifted to display only a part of the outer shape of the SIN operator 103. Note that this display is to indicate that they are overlapping, and to distinguish them from other non-overlapping operators. Thus, other methods, such as simply COS operator 104
May be changed to indicate that they are overlapping.

Next, when converting the created block diagram into simulation data, the higher-order operator of the overlap (that is, COS operator 104: operator number 7) is the same as the other non-overlapping operators. , But the lower order operator of the overlap (that is, the SIN operator 1
03: operator number 3) is the lower-order operator data non-conversion unit 2
Since it is detected by 8 that a numerical value other than 0 is set in the upper operator number setting area 21 of the operator data, it is not converted into simulation data. FIG. 5B shows the converted simulation data. However, the data is once converted, but it may be treated as a comment in the simulation data so that it is simply a comment when read by the simulation program.

Next, a procedure for reversing the overlapping of the overlapping operators to return to the initial block diagram will be described with reference to FIG. By specifying the overlapping upper operator (COS operator 104) with the mouse, the operator data of the specified operator (COS operator 104: operator number 7) is output by the upper / lower operator switching unit 25. The lower operator number and the upper operator number in the operator data of the operator (SIN operator 103: operator number 3) that overlaps below are exchanged. The result of the replacement is shown in FIG. The following procedure is shown in FIG.
Is the same as In the overlap operator display unit 27, looking at the operator data shown in FIG.
Is displayed on the back side and the SIN operator 103 is displayed on the front side as shown in FIG. When converting to simulation data, the lower-order operator data non-conversion unit 28 similarly does not convert the lower-order operator (COS operator 104: operator number 7). With this function, the upper order and the lower order can be switched, so that the display and the simulation data can be switched.

The operation of the user according to the present embodiment is simply to arrange the operator and select the operator with the mouse.
This operation is within the range of the operation of the conventional block diagram creation system, and the user does not need to learn a new usage method.

Although the above description has been made on the assumption that two operators overlap, the same applies to a case where three or more operators overlap. Even in this case, only the operator at the highest level is valid. That is, according to the present invention, when the operator is changed, the operator before the change can be kept, and the change before the change can be more easily performed. You can replace the later operator. From this, it is possible to easily calculate in a short period of time if it is calculated, and if a problem occurs, it can be undone.
The efficiency of creating a block diagram is greatly improved. According to the present invention, an effective simulation can be performed.

[Embodiment 2] Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.

(I) Overall Configuration FIG. 8 shows a specific configuration of this embodiment. The illustrated device includes a computer main body 11, a display 12, a mouse 13, and a keyboard 14 connected to the computer main body 11, and includes a block diagram creating section 15, a block diagram It comprises a display unit 17, block diagram data 16, and a data conversion unit 18. The simulation data 19 is created by converting the block diagram data 16 by the data conversion unit 18.

The block diagram creation unit 15 includes a signal line number setting unit 33, an uppermost signal line number setting unit 34, a lower signal line flag setting unit 35, and an uppermost signal line number changing unit 36. In the operator data in the block diagram data 16, an area 30 in which two or more signal line numbers are set to the same terminal among signal lines connected to the operator, and an uppermost signal line number thereof are set. There is a region 31 (in the present invention, when the start point side or the end point side of a plurality of signal lines are connected to the same terminal, the signal lines are referred to as overlapping. Also, in the overlapping signal lines, , Overlapping on the upper side is referred to as upper, and overlapping on the lower side is referred to as lower.) The signal line data in the block diagram data 16 includes a lower signal line flag setting area 32 indicating that the signal line is a signal line other than the highest signal line. This area 3
The settings of 0, 31, and 32 are performed by the signal line number setting unit 33, the highest signal line number setting unit 34, the lower signal line flag setting unit 35, and the highest signal line number changing unit 3 of the block diagram creation unit 15.
6 is set. The block diagram display section 17 includes an overlapping lower operator display section 37, an overlapping lower signal line displaying section 38, an overlapping upper operator displaying section 39, and an overlapping upper signal line displaying section 40. The data conversion unit 18 includes a non-conversion unit 41 for overlapping lower-order operator data and a non-conversion unit 42 for overlapping lower-order signal line data.

(Ii) Mutual relationship and operation of each component In this embodiment, two or more signal line numbers can be registered in the operator data so that two or more signal lines can be connected to the operator terminal. And a valid (ie, uppermost) signal line number among two or more signal lines can be set. In addition, of the two or more overlapping signal lines, the valid one and the operator connected to it are:
It may be displayed in the same manner as other signal lines and operators, or may be displayed as a thick line or the like for distinction. The remaining signal lines (invalid signal lines) and the operators connected to them are distinguished from other signal lines and operators by, for example, displaying them with broken lines. Furthermore, when converting the created block diagram into simulation data, only one valid signal line among two or more signal lines and the operator connected thereto are converted, and the other signal lines and the signal lines connected thereto are converted. Is not converted. In addition, there is provided a means for invalidating a valid signal line among two or more signal lines and changing one of the other signal lines to a valid state instead. In the first embodiment, two or more operators are set for one signal line, and one of the operators is made effective. However, in the present embodiment, one operation is performed. Two or more signal lines are set in the slave, and one of the signal lines is made effective.

FIG. 9 shows operator data in the block diagram of the present invention, and FIG. 10 shows signal line data.
Compared with the data of the block diagram of the prior art shown in FIG. 3B, in the operator data, a plurality of signal line number setting areas 30 for each terminal and a highest signal line number setting area 31 for each terminal are provided. Are added, and in the signal line data, a lower signal line flag setting area 32 is added. Here, the flag is set to a numerical value of 0 or 1, and if 0, it indicates the same signal line as the conventional one, and if it is 1, it is realized by the present embodiment. Represents a signal line. That is, the flag is a mark indicating the attribute of the signal line by its numerical value. 11 and 12 will be described later.

FIG. 13 is a display example of a block diagram.
(A) shows a block diagram in one page as it is (this figure is the same as (a) in FIG. 3). This embodiment will be described with reference to FIGS. 13B to 13E with respect to FIG. 13A. FIG. 13B is a block diagram of FIG.
04 is newly arranged and new signal lines 130 and 131 are wired. The new COS operator 104 and the signal lines 130 and 131 are indicated by thick lines, and the conventional SIN operator 103 and its SIN operator are displayed. Signal line 1 connected to
32 and 133 are indicated by broken lines. FIG. 13 (c) is a modification of the display form of the signal line of FIG. 13 (b), and FIG. 13 (d) is the operator and signal line of FIG. 13 (c). It is displayed by replacing the bold line and the broken line. (E) of FIG. 13 is obtained by adding a square operator 116 in series to the COS operator 104 of (c) of FIG.

In this embodiment, 30 to 42 in FIG.
Is realized by the components. The specific movement will be described with reference to FIG. First, the user creates a block diagram shown in FIG. The data in this block diagram is
9 and 10. In this state, since only one signal line is connected to each terminal, only one signal line number is set in the signal line number setting area 30 of the operator data in FIG. Further, 0 (zero) is set in the uppermost signal line number setting area 31 because there is no overlap of the signal lines. Also, since the signal line data shown in FIG. 10 does not overlap with the signal line, that is, the signal line is not at the lower level, (zero) is set in the lower signal flag area 32. When this block diagram data is converted into simulation data, it becomes FIG.

From the state of FIG. 13 (a), as shown in FIG. 13 (b), a COS operator 104 (operator number 7), which is a new operator, is used as a block diagram using the mouse 13, for example. And a signal line 130 (signal line number 6) connects between the proportional operator 106 and the newly arranged COS operator 104, and the newly arranged COS operator 104 and the integral operator 107 are similarly connected. They are connected by a signal line 131 (signal line number 7). At this time, the signal line 134 is already connected between the terminal 132 of the proportional operator 106 and the SIN operator 103.
And the terminal 133 of the integration operator 107 has SIN
Since there is a signal line 135 between the operator 103 and the
And 131 are the second signal lines for the terminals 132 and 133, respectively. From this, two terminals are respectively connected to the terminal 132 of the proportional operator and the terminal 133 of the integral operator.
Since the signal lines are connected, it is determined that the signal lines overlap. At the same time, the operator data shown in FIG. 9 includes the data of the newly arranged COS operator 104 (operator number 7) and the data of the proportional operator (operator number 2) and the integral operator (operator number 4). The data (signal line numbers 6 and 7) of the second signal lines 130 and 131 are set in the signal line number setting areas 30 of the terminal 2 of the operator number 2 and the terminal 1 of the operator number 4, and a plurality of Among the signal lines, the highest signal line 130,
The numbers 131 (signal line numbers 6 and 7) are set in the uppermost signal line number setting areas 31 of the terminal 2 of the operator number 2 and the terminal 1 of the operator number 4, and FIG. Further, FIG.
The two signal lines 13 newly wired to the signal line data shown in FIG.
The data of 0 and 131 (signal line numbers 6 and 7) are set, and the signal lines 132 and 133 connected to the SIN operator are further set.
Since (signal line numbers 2 and 3) are lower-order signal lines, 1 is set in the lower-order signal line flag setting area of that signal line, and FIG.
It becomes 2.

Regarding the display, the uppermost signal lines 130 and 131 (signal line numbers 6 and 7) and the operator (COS operator 104) connected to the signal lines are connected to other signal lines and operators. For discrimination, the signal line numbers (6 and 7) set in the uppermost signal line number setting area 31 of the operator data are checked, and the upper signal line display section 40 displays the uppermost signal lines 130 and 132 (signal line numbers). Numbers 6 and 7) are indicated by bold lines, for example, and the operator (COS operator 104) connected to the signal line
Are also displayed by the upper operator display section 39 in bold lines. On the other hand, for the signal lines 134 and 135 (signal line numbers 2 and 3) which are not the highest order, 1 is set in the lower signal line flag setting area 32 of the signal line data, and the signal line is displayed as the lower signal line. The operator (SIN operator 103) connected to the signal line is displayed as a broken line by the lower operator display unit 38. In other words, the data is displayed with a broken line to indicate that the data is not converted into simulation data. However, since it is also used to distinguish it from other block diagrams, it may be displayed in a color other than the broken line, for example, by changing the color.

Next, when converting the created block diagram into simulation data, the operator (SIN operator 103) indicated by the broken line and the signal lines 135 and 134 (signal line numbers 2 and 3) are subjected to lower-order operations. The invalidity is detected by the child data non-conversion unit 41 and the lower signal line data non-conversion unit 42, and is not converted into simulation data. Signal lines and operators indicated by bold lines are converted into simulation data in the same manner as ordinary signal lines and operators.
As a result, the block diagram indicated by the broken line is not converted. The converted simulation data is shown in FIG.

By the way, the operator and the signal line before the correction are not converted, and both the operator data and the signal line data remain. Therefore, it is easy to return to the original state. For example, as shown in FIG. 13D, by inverting the COS operator 104 indicated by a thick line and the SIN operator 103 indicated by a broken line as compared with FIG. 13C,
Can be undone. More specifically, as shown in FIG.
Is specified, the signal line data of the signal lines 132 and 133 connected to the operator is connected to the operator whose signal line whose numerical value is changed is connected to the operator (proportional operator 106, integration In the operator data (operator numbers 2 and 4) of the operator 107), the signal line numbers 6 and 7 in the uppermost signal line number setting area 31 are changed to the signal line numbers 2 and 3 whose numerical values have been changed. Lastly, the lower signal line flag setting area of the signal line overlapping with the signal line whose numerical value has been changed (signal line numbers 6 and 7: These signal lines can be seen by looking at the signal line number setting area 30 of the operator data). The value of 32 is set to 1. As a result, the operator data shown in FIG. 11 is shown in FIG. 16A, and the signal line data shown in FIG. 12 is shown in FIG.
become.

The block diagram display section 17 displays operators and signal lines based on the block diagram data.
3 (d), the SIN operator 103 and the COS
The display of the broken line and the solid line of the operator 104 is reversed. In the conversion to the simulation data, too, the operator whose lower operator setting area of the operator data is 1 is not converted, and the signal line whose lower signal line area of the signal line data is 1 is not converted.
Contrary to the case (c) of FIG. 3, the data of the COS operator 104 is not converted, and the data of the SIN operator 103 is converted. The converted simulation data is shown in FIG.
Thus, the original simulation data can be easily created.

In this embodiment, the operation to be realized is also within the range of the operation of the conventional block diagram creating system as in the first embodiment, and the user newly learns the usage method. do not have to.

In this embodiment, when an operator or a signal line is changed, the operator or signal line before the change can be left, and the operator before and after the change can be easily replaced. . From this, it is possible to easily calculate in a short period of time if it is calculated, and if a problem occurs, it can be undone.
The efficiency of creating a block diagram is greatly improved. The present invention enables efficient simulation.

Further, in the first embodiment, the operator is simply replaced with another operator. In this embodiment, since both the operator and the signal line are replaced, (e) in FIG. ), It is possible to replace one operator with a plurality of operators, and it is possible to easily cope with a complicated change of a block diagram.

As described above, by using the present invention, it is possible to easily represent a block diagram.

[Embodiment 3] Hereinafter, a third embodiment of the present invention will be described with reference to the drawings.

(I) Overall Configuration FIG. 17 shows a specific configuration of this embodiment. The device shown is
The computer main body 11 includes a display 12, a mouse 13, and a keyboard 14 connected to the computer main body 11. The computer main body 11 includes a block diagram creating section 15, a block diagram display section 17, and a block diagram. It is configured to include diagram data 16 and a data converter 18. The block diagram creation unit 15 includes, in addition to the configuration of the embodiment shown in FIG. 8, an upper / lower page number setting unit 52 for setting the overlapping relationship of pages and an upper / lower page changing unit 53 for changing the upper / lower relationship of pages. The block diagram data 16 includes the upper page number setting area 5 in the page data.
0, a lower page number setting area 51 is added. The remaining configuration is the same as that of the second embodiment shown in FIG.

(Ii) Interrelationship and Operation of Each Constituent Part In this embodiment, in the first or second embodiment, newly added operators and signal lines are grouped in units of pages, and are distinguished from the conventional block diagram. Separately, the block diagram can be changed more easily. In addition, the page describing the new block diagram is superimposed on the page describing the conventional block diagram and transparently displayed. Operators and signal lines to be changed in the conventional page are displayed in broken lines, and simulation data is displayed. In the conversion, the operators and signal lines indicated by the broken lines are not converted. FIG. 18A shows page data according to the present embodiment. Compared with the page data shown in FIG. 40C of the prior art, an upper page number setting area 50 and a lower page number setting area 51 are added. ing. When the overlapping page is higher than the page, that is, when the overlapping page includes the changed block diagram, the page number of the overlapping page is set in the upper page number setting area 50, If the overlapping page is lower than the page, that is, if the page includes the changed block diagram, the page number of the overlapping page is set in the lower page number setting area 51. In the setting areas 50 and 51, when the pages are overlapped, the overlapping page number is set in one of the areas. When the pages do not overlap, 0 (zero) is set in both the setting areas 50 and 51. Is set.

The specific display of the block diagram will be described by taking as an example a case where the page shown in FIG. 19B is superimposed on the conventional page 1 shown in FIG. In this case, as shown in the page data of FIG. 18B, the page number 2 is set in the upper page number setting area 50 of the page number 1 and the lower page number setting area of the page number 2 is set. The page number 1 is set to 51, and the block diagram described in the page number 2 is a changed block diagram. As a result,
The block diagram displayed on the display 12 is shown in FIG.
As shown in (c) of FIG.
And the signal lines connected to the SIN operator 103 are indicated by broken lines, and the COS operator 104 and the signal lines 140 and 141 are indicated by solid lines.

This embodiment is characterized by the constituent elements 50 to 53 in FIG. FIG. 20 shows a specific operation. A conventional page (page number 1) shown in FIG. 19A (this figure is the same as FIG. 3A) is displayed, and a new page (page number 2) is overlaid thereon. At this time, in order to set that the page has been overlapped with the page data, the upper and lower page number setting unit 52 uses the page number of the page newly added to the upper page number setting area 50 of the page data of the conventional page (page number 1). Set a certain 2.
Conversely, the conventional page number 1 is set in the lower page number setting area 51 of the page data of the new page (page number 2). Next, as shown in FIG. 19B, a new operator 104 (operator number 7) and signal lines 140, 1
41 (signal line numbers 6 and 7) are arranged and wired. The new operator number 7 and signal line numbers 6 and 7 are set in the page data of page number 2. Thus, the new page data is as shown in FIG. Since the operator data and the signal line data are the same as in the second embodiment, they are shown in FIGS. Further, since the new operator and the signal line belong to a new page, if only that page is displayed, the result is as shown in FIG. 19B. However, the new page is transparently superimposed on the conventional page. Because it is displayed, FIG.
(C). In other words, since multiple pages are superimposed and displayed transparently, it seems that new operators and signal lines are arranged and wired on the block diagram of the conventional page, but in reality, new operators and signal lines are arranged. When wiring signal lines, those operators and signal lines belong to a new page.

In order to display a plurality of pages transparently, first, a block diagram in the lowest page is displayed.
Subsequently, it is only necessary to display the block diagram of the upper page and finally display the block diagram of the uppermost page, which is a general prior art.

The method of setting numerical values to operator data, signal line data, displaying a block diagram, and converting to simulation data are the same as those in the second embodiment shown in FIG. I do. The operator data is shown in FIG.
1, the signal line data is shown in FIG. 12, and the result of conversion into the simulation data is shown in FIG. 5B, which is the same as in the second embodiment.

The change can be undone by changing the new page below the conventional page, that is, by reversing the upper / lower relationship of the page data.
The number set in the upper page number setting area 50 of the page data and the number set in the lower page number setting area 51 are reversed by the upper / lower page changing unit 53.
That is, upper page number 2 of page 1 is moved to lower page number setting area 51, and lower page number 1 of page 2 is moved to upper page number setting area 50. The page data after the setting change is shown in FIG. The change of the operator data and the signal line data is the same as in the case of the second embodiment, and the results are as shown in FIGS. 16A and 16B, which are the same as in the second embodiment. FIG. 21 shows the above procedure for restoring the change. When the change is undone by the above operation, the display on the display 12 becomes the block diagram shown in FIG. That is, it is very easy to undo the changes.

In this embodiment, the operation to be realized is also within the range of the operation of the block diagram creating system of the prior art similarly to the first and second embodiments, and There is no need to learn new usage.

(Iii) Effects peculiar to the present embodiment Also, as in the present invention, when pages are overlapped and only the changed portion is created in a new page, a plurality of block diagrams having slightly different block diagrams but many identical portions are created. If the block diagram on the lower page is made common and different parts are created on the page to be overlaid, only one block diagram on the lower page needs to be created. The amount of figures is reduced. For example, referring to FIG. 19, when two types of block diagrams (c) and (e) are created in addition to (a), two types of block diagrams (c) and (e) are created, respectively. Instead, only the block diagrams of (b) and (d) are newly created and can be created by superimposing them on (a). Compared with (c) and (e), (b) and (d) have fewer operators and signal lines, so that the same block diagram as the conventional one can be created with a smaller amount of block diagrams. Further, the changed portion and the portion that is not changed can be considered separately as a lower page and an upper page, so that an easy-to-understand block diagram can be obtained. In addition, when the common portion is corrected by this, only the original block diagram needs to be corrected, so that the correction can be easily performed, and it is not necessary to confirm whether or not all the corrections have been made.

As described above, the block diagram in which the modules that can be used in common are created can be displayed in an easy-to-understand manner, the data creation time can be reduced, and the efficiency of the simulation can be increased.

Embodiment 4 Hereinafter, a fourth embodiment of the present invention will be described with reference to the drawings.

(I) Overall Configuration FIG. 22 shows the configuration of this embodiment. The illustrated apparatus includes a computer main body 11, a display 12, a mouse 13, and a keyboard 14 connected to the computer main body 11, and includes a block diagram creation section 1 in the computer main body 11.
5, block diagram display section 17, block diagram data 1
6. The data conversion unit 18 is included. The block diagram creation unit 15 is provided with a corresponding in-page operator parameter setting unit 43 for setting the parameters of the operator in the corresponding page through the page operator. , An operator number and a parameter value setting area 44 are provided. In the block diagram display section 17, a corresponding page display section 47 and a parameter display section 45 are provided, and the parameter display section 45 includes a parameter value display section 46 for displaying parameter values in page operator data. ing. Further, the data conversion unit 18 is configured to include a parameter value replacement unit 48 that replaces the parameter value of the operator in the corresponding page with the parameter value in the page operator data.

(Ii) In this embodiment, a setting area 44 for setting an operator number and a parameter value in the corresponding page is provided in the page operator data in addition to the page number of the corresponding page in the related art. The operator parameter setting unit 43 in the corresponding page for setting the parameter number and the operator number for changing the parameter value in the area 44 is changed to the block diagram creation unit 15.
It is provided inside. Further, a corresponding page display unit 47 for displaying a block diagram of the corresponding page is provided, and a parameter value display for displaying the set parameter value instead of the parameter value before the change on the screen displaying the block diagram of the corresponding page. A part 46 is provided. Further, when the created block diagram is converted into the simulation data, a parameter value replacement unit 48 is provided which replaces the parameter value of the operator in the corresponding page with the parameter value in the page operator data.

FIG. 23 is a display example of the operator data of the block diagram of the present embodiment, and FIG. 24 is a display example of the block diagram of the present embodiment. FIG. The diagram is displayed as it is. That is, the corresponding page is not displayed through the page operator. (The expression "through the page operator" will be described later.) Below each operator, parameter values used for the operation of each operator are displayed. FIG.
(B) of FIG. 24 shows a page including a page operator in which the page of (a) is set as a corresponding page, and FIG.
(C) shows the corresponding page (a) displayed through the page operator in (b). In FIG. 24 (c), two pixels from the left are used according to the present invention.
The parameter of the third operator (proportional) has been modified to a value different from that of (a).

First, the user operates the mouse 13 and the keyboard 14 to create the block diagrams shown in FIGS. 24A and 24B by the block diagram creating section 15. Block diagram data 16 is obtained from the created block diagram. The block diagram data 16 is stored in the block diagram display 1
7 is displayed on the display 12. The process up to this point is the same as the above-described conventional technology.

The feature of this embodiment is realized by the configuration from the operator parameter setting unit 43 to the parameter value replacing unit 48 in the corresponding page in FIG. As shown in FIG. 25, for example, the page operator 108 is clicked using the mouse 13, and the corresponding page designated by the page operator is displayed by the corresponding page display unit 47. This is referred to as displaying the corresponding page "through the page operator".
At this time, the parameter value 45
09 is displayed. Next, the parameter value to be changed is clicked (in the example of FIG. 24A, the parameter value of the second operator (proportional) from the left is clicked), and the changed value is input from the keyboard. By this operation, the operator number for changing the parameter and the new parameter value are set in the corresponding page operator setting area 44 of the block diagram data 16 by the corresponding in-page operator parameter setting unit 43 from the page operator. Is set. At the same time, the parameter value display unit 46 in the page operator data displays a new parameter value input from the keyboard 14, that is, a parameter value after the change, instead of the parameter value before the change. At this time, in order to clearly indicate that the parameter value has been changed, for example, it is desirable to display the changed parameter value in a character having a color different from the color of the parameter value that has not been changed.

The parameter value changed in this way is valid only for the page operator in which the changed value is set. This change is not visible when viewing the same corresponding page from another page operator (through the other page operator). As a result, for the same corresponding page, it is possible to change parameters that are valid only within that page operator for each page operator, so it is possible to set different parameter values for each page operator for the same corresponding page. it can.

Next, when the created block diagram is converted into simulation data, the page operator data is confirmed. If the operator has not been changed, the parameter values set in the operator data remain unchanged. Although the operator is output, if the operator has been changed, the parameter value of the operator in the corresponding page is set in the operator data by the parameter value replacement unit 48 which replaces the parameter value with the value set in the page operator data. Instead of the parameter value
The changed parameter value set in the page operator data is output.

That is, in this embodiment, different parameter values can be set from the page operator side for each page operator for the same block diagram.
This means that the simulation can be performed using the heat exchange module, which is the same corresponding page, and using the operation parameters corresponding to the superheater, the reheater, and the economizer set individually on the page operator side. In other words, by setting only the different parts, for example, only the parameters,
This eliminates the need to copy pages, which has been conventionally performed, not only saving the amount of memory storage, but also improving the efficiency of creating a block diagram and enabling efficient simulation.

Embodiment 5 Hereinafter, a fifth embodiment of the present invention will be described with reference to the drawings.

(I) Overall Configuration FIG. 26 shows a specific configuration of this embodiment. The device shown is

The corresponding page operator signal line deletion unit 54 and the setting area 4
9 is provided with an in-page operator signal line addition creating section 55 for setting the operator and signal line number newly added. The newly added operator and signal line are set to the operator data and signal line data, and the parameter value of the added operator is set by the corresponding intra-page operator parameter setting unit 43. Although the fourth embodiment is an example in which the parameter value of the operator is changed, the present embodiment is an application of the present invention to a case in which the operator and the signal line are changed.

FIG. 29 is a display example of a block diagram of this embodiment. FIGS. 27 and 28 show operator data and signal line data of the block diagram shown in FIG. 29, respectively. FIG. 29A shows a block diagram of one page as it is, and parameter values for operation of each operator are displayed below the operator. (B) of FIG. 29 shows a page including a page operator that makes the page of (a) the corresponding page, and (c) of FIG. 29 shows the page operator through the page operator in (b). The corresponding page (a) is obtained by removing the integration operator 107 and its input and output signal lines. FIG. 29 (d) shows an addition operator 136 after the operator deleted in (c).
And signal lines 138 and 139 on the input side and output side thereof, and a constant value operator 137 connected by a signal line 142 to the input side of the added addition operator 136.

Next, in the displayed corresponding page (that is, (a)), the operator and the signal line are created by the corresponding in-page operator signal line addition creating unit 55, and the corresponding in-page operation is performed in the same manner as the operation in the normal page. The operator and the signal line are deleted by the child signal line deletion unit 54, and the parameter is changed by the operator parameter setting unit 43 in the corresponding page. However, if deleted, the operator and signal line in the corresponding page are not deleted, and the data of the page operator 108

Only when you view the corresponding page (by clicking on), it will be displayed in a changed state. When the same corresponding page corresponds to a plurality of page operators including the page operator 108, even if the same corresponding page is viewed through another page operator, the changed block changed through the page operator 108 The diagram is not visible. In other words, for the same corresponding page, for each page operator, it is possible to change the block diagram that is valid only for that page operator, so set a different block diagram for the same corresponding page for each page operator You can do it. If the corresponding page is displayed without passing through the page operator, the changed portion is not displayed.

Next, when the created block diagram is converted into simulation data, the data of the page operator is confirmed, and if the operator is not changed, the operator data is output as before. If the operator data has been changed, the deletion operator, the deletion signal line non-conversion unit 59,
The additional operator / additional signal line conversion unit 60 outputs the changed operator data set in the operator data.

That is, in this embodiment, it is possible to set different block diagrams from the page operator side for the same block diagram (in other words, the same corresponding page). For this reason, when creating or changing a block diagram corresponding to a plurality of page operators, the duplication of pages conventionally performed becomes unnecessary, and work efficiency is improved.
This has the effect of enabling efficient simulation.

As described above, according to this embodiment, the block diagram can be easily understood. Also, instead of setting the corrected operator number and signal line number in the corresponding page in the page operator data, a new page is created and corrected to the page data as shown in FIG. Even if the content is set and an additional page number item is provided in the parameter value of the page operator data as shown in FIG. 31 (a), and the newly created page number is specified there, the effect remains. Are identical.

Embodiment 6 Hereinafter, a sixth embodiment of the present invention will be described with reference to the drawings.

(I) Overall Configuration FIG. 32 shows a specific configuration of this embodiment. The device shown is
The computer main body 11 includes a display 12, a mouse 13, and a keyboard 14 connected to the computer main body 11. The computer main body 11 includes a block diagram creating section 15, a block diagram display section 17, and a block diagram. It is configured to include diagram data 16 and a data converter 18. The block diagram display unit 17 searches for operators whose parameters have been changed through page operators (see the fourth embodiment), deleted operators, and signal lines (see the fifth embodiment). A part 97 and a broken line color change display part 98 for displaying the searched operator and signal line by broken line or by changing the color are displayed.

(Ii) Interrelationship and Operation of Each Constituent Part In this embodiment, the corresponding page is set not from the block diagram side,
This is an example in which, when a block diagram is displayed as a mere page, it is possible to distinguish and display an operator changed or deleted from the page operator side and whether or not the signal line. That is, when the corresponding page is displayed on the display 12 as a simple page rather than from the block diagram side, the search unit 97 searches the column of the page operator of the operator data and finds the page to be displayed. Check if there is a page operator to be the corresponding page. If there is such a page operator, it is checked whether the page operator has an addition operator, a deletion operator, an addition signal line, a deletion signal line, and whether an operator parameter has been changed. If any of them is confirmed, the broken line, color change display unit 98 displays the confirmed operator, signal line or parameter on the screen in a broken line or a different color.
If there is no page operator that uses the page you want to display as the corresponding page, or if there is a page operator that uses the page you want to display as the corresponding page, add or delete operators for that page operator , Additional signal lines,
If the deletion signal line is not set and the parameter is not changed, the block diagram of the page is displayed as a solid line as it is.

FIG. 33 shows that the operator “integration” and the signal lines connected to this operator are displayed as dashed lines as operators and signal lines deleted through the page operator.
This is an example in which operators and signal lines that have not been deleted are displayed as solid lines. Operators removed through page operators,
The signal lines may be displayed not only by broken lines, but also by changing the color of the lines, or by distinguishing them by a method such as shading or filling.

In the fourth and fifth embodiments, when a block diagram partially modified from a certain block diagram (module) is generated, the original block diagram is not copied. Then, only the changed part is newly created, and the two are combined to obtain a changed block diagram (module). This means that when modifying the block diagram of a common part that is not a change for each module, only the corresponding original page needs to be modified. In the modification work of the corresponding page as the base, instead of clicking the page operator to display the corresponding page as in the fourth and fifth embodiments, the block diagram directly as the base is used. Will be displayed and a correction will be made. At this time, for operators and signal lines that have been deleted or changed on the page operator side, even if the page on which the original block diagram is described is displayed and corrected, the correction is performed by the page operation. Since it is not reflected on the child side, the operator described in the original block diagram, which of the signal lines has been deleted, changed, etc. through the page operator,
It is important to know if it is a signal line.

In this embodiment, since the operator and the signal line corrected on the page operator side can be easily recognized on the screen, it is possible to distinguish whether it is necessary to simply change or to correct through the page operator. The block diagram can be easily corrected.

[0093]

According to the present invention, it is possible to create a block diagram after a change while leaving the block diagram before a change, and to change a block diagram to be displayed and a block diagram to be converted into simulation data. Since it is possible to easily replace the previous one with the changed one or vice versa, trial and error during the creation of a complicated block diagram can be easily performed. In addition, a partial block diagram can be easily changed, and a complicated block diagram can be made an easy-to-understand block diagram.

Further, according to the present invention, the same operation as the operation of the conventional block diagram creation system, that is, the operation of arranging a new operator, wiring a signal line, and creating a new page, that is, the conventional operation, By exactly the same operation as above, the created block diagram can be displayed in an easily understandable manner, and trial and error can be easily performed.

According to the present invention, the block diagram can be partially changed for each module without duplicating the corresponding page, and not only the partial change for each module but also each module can be changed. Modification of the block diagram commonly used by the modules is also facilitated.

That is, according to the present invention, since the data creation time for generating the block diagram can be shortened and can be realized by exactly the same operation as the conventional one, the user needs to get used to the operation of the new machine. And simulation efficiency can be improved.

Therefore, the same simulation as that of the prior art can be performed in a short time, and more simulations can be performed in the same time.
It is possible to greatly increase the design efficiency of a plant that needs to create a large-scale block diagram such as a boiler.
