Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block diagram display device and a block diagram display method suitable for performing dynamic analysis of various plants such as a boiler and control analysis of an automatic control system.

[0002]

2. Description of the Related Art In order to analyze the operation of a simple pendulum as shown in FIG.
When the length of 00 is L, the swing angle of the pendulum 100 is φ, and the gravitational acceleration is g, it is necessary to solve the equation MLφ ″ + Mgsinφ = 0.

When solving such a linear or non-linear problem of a mechanical system or a control system, a method of simulating it with a computer and solving it is used. In the case of the example of FIG. 13, an operator 10 for integration, proportionality, etc. as shown in FIG.
1 to 104 and signal lines 105 to 1 for transferring data between the operators 101 to 104, respectively.
A block diagram composed of 08 and 08 is drawn, input data is created based on the block diagram, and a simulation-dedicated program is run using the data to solve.
In this method, the signal input to each operator from each signal line is operated in each operator, and the result is output from each signal line. In addition, hereinafter, the end point marked with the arrow of the signal line is the end point,
An end point without an arrow is called a start point. That is, the signal is transferred from the operator on the starting point side of the signal line to the operator on the ending point side. The feature of the solution using this block diagram is that the connection between operators can be seen at a glance by tracing the signal line.

A solution using a block diagram is also used when analyzing the operation of a complex mechanical system such as a boiler, or a control system. However, in this case, the system configuration is complicated,
You have to create a large-scale block diagram that combines thousands of operators. Therefore, the block diagram is divided into multiple areas, each divided area is called a page, a block diagram is created for each page, and these pages are combined to create a large-scale block diagram. A method of creating a diagram is being performed.

When creating a block diagram on a page-by-page basis, it is necessary to transfer signals between pages, and there is known a method of transferring signals between pages using connection terminals (input and output). There is. In this method, the connection terminal uses the information (connection terminal number,
When a signal is input to the page's connection terminal (output) via a signal line, the signal is delivered to the connection page (input) of the other page. Further, a signal is transferred from the connection terminal (input) to another operator on the page via the signal line.

For example, when creating a block diagram as shown in FIG. 15 (a), the block diagram is too large and the block diagram is included in one page P as shown in FIG. 15 (b). When it is not possible, I will divide this block diagram into multiple pages. As a method of dividing this, for example, as shown in FIG. 6C, the two operators on the left side of FIG. There is a method of dividing the two operators on the right side and their signal lines into other pages (this page is referred to as page B). In this case, from the operator at the right end of page A,
It is necessary to pass a signal to the operator of page B, and as shown in FIG. 7C, page A has an output connection terminal O3 for outputting a signal to another page, and page B has another page. An input connection terminal O6 for inputting a signal from is provided. In the connection terminals O3 and O6, the connection terminal information of the signal transfer destination is set as the partner operator number and page number. In the case of FIG. 15C, the connection terminal O3 of page A transfers a signal to the connection terminal O6 of page B.

In the above-mentioned method, page data for displaying a page is given a unique number within the computer when an operator and a connection line that make up the page are created, and thereafter managed by that number. To be done.

Furthermore, in this method, as for operators and signal lines in the same page, as shown in FIG. 16, individual operator and signal line numbers are set in page data in page units, and the computer main body is set. Stored in the storage device. As shown in FIG. 17, the operator data related to each operator is connected with the operation content, coordinate values for display (blank in the figure, but concrete coordinate data is actually stored). It is composed of the number of the signal line to be connected. As shown in FIG. 18, the signal line data includes coordinate values for display (see FIG.
Similarly, although it is a blank field, concrete coordinate data is actually stored) and operator numbers connected to the start point and the end point side, respectively. The connection terminal is treated as an operator as data, and in addition to the operation content of connection,
The display coordinate value, the number of the signal line to be connected, the number of the connection terminal of the other party to which the signal is transferred, and the page number are set as the connection information.

In the conventional block diagram display method,
A block diagram is displayed page by page on a display screen of a display device of a computer, and a block diagram is created for each page. That is, the page is displayed by confirming the operator and signal line number in the page to be displayed with the page data and displaying the operator and signal line of that number.

In this method, the pages are displayed on the display screen page by page. Therefore, when creating another page, the displayed page must be switched. That is, it is necessary to create a block diagram composed of a plurality of pages while switching pages. At that time, signals between pages are transferred using the connection terminals.

[0011]

In the conventional block diagram display method, for example, as shown in FIG.
After the page A was created using the operators O1 to O3 and the signal lines SL1 to SL2, the page B was created using the operators O4 to O6 and the signal lines SL3 to SL4.
After creating both pages A and B, whether the information set in the connection terminals O3 and O6 is correct, page A and page B
While switching the display of, it was confirmed visually, and if it was incorrect, it was corrected to a value that allows correct connection.

According to such a method, the connection between operators within the same page can be determined at a glance by looking at the connection of the signal lines, but the connection between pages using the connection terminal is It is necessary to check while watching the connection information set in, and switching the display of the connected pages.Since there is no connection with the signal line, check the connected page and change the displayed page. I had to switch, and I couldn't tell at a glance whether or not it was correct.

Therefore, it takes time to confirm whether the connection between the pages is correct, and the possibility of overlooking the incorrect connection is greater than in the case where the signal line is directly connected. Therefore, depending on the conventional block diagram display method, it takes a lot of time to create a correct block diagram, and there is a problem that the creation efficiency is poor.

The present invention has been made in order to solve the problems of the conventional block diagram display method or block diagram display device, and the connection relationship between the connection terminals between pages or between the signal lines. Can be determined at a glance, and therefore whether the connection between pages is correct can be seen at a glance, the confirmation time for correctness can be shortened, and the possibility of overlooking an incorrect connection is extremely small, which in turn leads to data creation time. It is an object of the present invention to provide a block diagram display device and a block diagram display method capable of shortening the time and improving the efficiency of simulation.

In addition, the connection signal line 64 and the portion of each page may be clearly displayed so as to be distinguishable from others by the line type, the coloring process, and the like, as in the first embodiment.

In the second embodiment, the connection terminals are not displayed, and the operators are directly connected by the connection signal line 64 to display the transfer of signals between pages. According to this method, as compared with the first embodiment, since there is no connection terminal, the connection between operators is easy to understand, and the block diagram is easier to understand.

As described above, in this embodiment, since the connection between pages can be expressed by the same signal line as the connection between operators, it is not necessary for the user to be aware of the page, and the operator that spans pages can be represented. It is possible to confirm at a glance whether or not the connection between them is correct. Therefore, the time required for creating the block diagram can be reduced, and the efficiency of creating the block diagram can be significantly improved.

In the first embodiment and the second embodiment, it is necessary to display a plurality of pages at the same time,
Since multiple pages do not fit on the display screen with the size as it is, multiple pages were simultaneously displayed on the same display screen by reducing each page. However, in the third embodiment described below. In the form, it is assumed that the virtual screen is larger than the actual display screen and includes the actual display screen as a part of the virtual display screen. Display a part of the entire block diagram displayed on the actual display screen.

FIG. 7 is a block diagram showing the configuration of the third embodiment of the present invention. In the figure, first and second
The same reference numerals are given to the same components as those of the embodiment of the present invention,
The description is omitted. In the third embodiment, a virtual screen setting unit 25 for setting the above-mentioned virtual screen is provided.

8 to 11 show display examples of block diagrams according to the third embodiment. In this display example, the display portion of each page is not reduced. Moreover, a part of the block diagram is displayed on the actual display screen.

Hereinafter, the display procedure of FIGS. 8 to 11 will be described with reference to FIG.
This will be described using the flowchart shown in FIG.

Similar to the second embodiment, the connection terminal searching unit 18 has a connection terminal for transferring a signal to and from a connection terminal of another page in the page data in the page to be displayed (page A). Search whether or not (step S
31) If it does not exist, the page is displayed as it is (step S32), and if it exists, the connection terminal number and page number (page B) of the partner to be connected to the connection terminal are obtained, and the page of the partner is obtained. The page data for displaying is searched (step S33). Next, the signal line search unit 23 connected to the connection terminal searches for the signal line connected to the connection terminal of page A (step S3).
4) The display data creation unit 24 creates the display data of page A except for the connection terminals and the signal lines searched in step S34 (step S35). Similarly for page B, the signal line connected to the connection terminal searched by the connection terminal search unit 18 is searched by the signal line search unit 23 connected to the connection terminal (step S36), and the display data creation unit 24 Display data is created excluding the connection terminals of page B searched in step S36 and the signal lines connected to them (step S37).

Subsequently, in the third embodiment, as shown in FIG.
As shown in FIG. 7, a virtual screen 66 having a size sufficient to display page A and its adjacent page B is set using the virtual screen setting unit 25 (step S38), and page A and page B are set on the virtual screen 66. Is displayed using the block diagram display unit 16 (step S39). Furthermore, on the virtual screen 66,
Similar to the second embodiment, the connection signal line data creation unit 21 creates data for the signal lines that connect pages, and the connection signal line display unit 22 creates operators for signal lines based on this data. It is wired and displayed at 64 (step S40).

Finally, a broken line 63a for distinguishing between pages is displayed on the virtual screen 66 by the page area display unit 20 so as to surround each page area. The line type and coloring of the broken line 63a and the background color of each page area may be different for each page, as in the first and second embodiments described above.

Since the virtual screen 66 of FIG. 9 is virtual, it is not displayed on the display screen 61 of the display device 12 in this form. Actually, a part of the virtual screen 66 is displayed on the display screen 61. Since only a part is displayed, the entire virtual screen 66 cannot be seen at a glance, but, for example, the scroll bars 65a, 6 on the upper or lower side of the display screen 61 and the left or right side may be displayed.
The entire virtual screen can be viewed while moving the screen displayed using 5b. By moving the scroll bars 65a and 65b with the mouse 13, the user can
By changing the display of FIG. 8 as shown in FIG. 10 and FIG. 11, a block diagram larger than the actual display screen can be confirmed.

That is, according to the third embodiment, for example, as shown in FIG. 8, a screen corresponding to page A is displayed on the display screen 61, and the user needs to confirm the connection status. , The scroll bar 65b is moved by the mouse 13 so as to display the right side of the page A, instead of switching the display to display the page B. As a result, as shown in FIG. 10, a part of the page A and the page B is displayed on the display screen 61 together with the connection signal line 64.
The connection state between B can be seen at a glance by the connection signal line 64. Furthermore, when the scroll bar 65b is moved, FIG.
A screen corresponding to page B can be displayed on the display screen 61 as shown in FIG. As described above, the connection between the pages can be represented by the connection signal line 64 by using the virtual screen 66 and the scroll bars 65a and 65b.

In the third embodiment, the block diagram is displayed on the virtual screen without displaying the connection terminal, but the connection terminal is displayed and the block line is displayed as in the first embodiment. You may make it display a figure.

Further, in this embodiment, since the block diagram is displayed without being reduced, the block diagram can be displayed in the same size as the conventional one. This has the advantage that even if the page has many operators and signal lines and it becomes too fine to understand if it is reduced, it will not be difficult to understand because it is not reduced.

As described above, in this embodiment, since the connection between pages can be expressed by the same signal line as the connection between operators, it is not necessary for the user to be aware of pages, and the connection between pages can be eliminated. You can check the correctness of at a glance. Therefore, it takes less time to create a block diagram,
Creation efficiency is greatly improved.

[0062]

According to the present invention, each page is reduced and the entire block diagram is displayed on the same display screen, or the entire block diagram is displayed on the virtual screen and the actual display screen is displayed. Since a part of it is displayed so that each part can be scrolled freely, all connections between connection terminals across different pages can also be displayed in a form connected by signal lines. Furthermore, since the operators across the pages can be directly displayed in the form of being connected using signal lines without displaying the connection terminals, the connection can be seen at a glance. Therefore, the wiring difference between the signal lines can be easily found, which facilitates the data creation, shortens the data creation time, and improves the simulation efficiency.

That is, the simulation with the same contents as in the conventional example can be performed in a short time, and more simulations can be performed at the same time, so that it is necessary to create a large-scale block diagram such as a boiler. Can be significantly increased.
