[0002]

2. Description of the Related Art In architecture / civil engineering design, mechanical design, etc.
By using a data processing device including a personal computer or the like, it is possible to create a calculation form in which a graphic such as a design drawing and various calculation formulas related to the graphic are combined and displayed. To create this kind of calculation sheet, use a keyboard, mouse, or other input means to display the required calculation formulas in a predetermined area on the display screen, and set the area for displaying graphics. Then, the coordinate axes are displayed in this area, the sub-commands related to drawing are displayed, and necessary items are input based on the sub-commands so that the figure can be drawn at a desired position in the coordinates. . Then, this graphic can be created by referring to the calculation formula displayed on the screen.

[0003]

By the way, the calculation sheet created by the data processing as described above is composed of the calculation formula and the figure. In the prior art, the calculation formula and the figure are mutually exchanged. It is processed by a separate processing system. Therefore, if you change the numerical value of the calculation formula related to the figure, to reflect the changed numerical value in the figure,
In order to correct the figure of the part corresponding to the changed numerical value, it is necessary to separately perform a predetermined input work, and this work is very troublesome.

The present invention has been made in view of the above points, and an object of the present invention is to set a value of a calculation formula in creating a calculation sheet including a figure and a calculation formula by data processing. When changing, it is to reflect it on the figure and change the figure according to the numerical value.

[0005]

In order to achieve the above-mentioned object, the present invention provides a calculation for processing formula data relating to mathematical formulas and symbolic formulas inputted from input means and graphic data relating to graphics, respectively. A calculation statement data processing device, comprising: a formula data processing unit and a graphic data processing unit, wherein the data processed by the calculation formula data processing unit and the graphic data processing unit are displayed on a display. In the section, arithmetic operations of numerical expressions consisting of numerical values and operators, registration of definition expressions that define predetermined symbols with variable numerical values, and symbolic expressions that combine the symbols and operators defined by numerical values and definition expressions For symbols, and the operation performed by substituting the numerical value defined by the definition formula,
Further, the graphic data processing unit executes graphic creation processing by inputting a numerical value or a symbol defined by the definition formula as a drawing parameter, and the symbol in the drawing parameter is defined by defining the symbol. It is characterized in that it is configured so that it is linked to the numerical value of the formula, and that when the numerical value of the defining formula is changed, the numerical value is reflected in the symbolic formula and the figure.

[0006]

As the input means, for example, the keyboard is operated to input the calculation formula. Here, as the expression, it is possible to use a numerical expression in which a numerical value and a required operator are combined, a definitional expression that defines a symbol by a numerical value, and a symbolic expression that is an expression including the symbol. Numerical expressions, for example, first enter a combination of a numerical value and operators such as addition, subtraction, multiplication and division, square root, etc. on the right side,
When the operator of the equal sign is input and a line feed is performed, the arithmetic processing unit executes the arithmetic operation of the value on the left side and at the same time, the numerical expression is displayed on the display screen. In the definition formula, enter a symbol on the left side of the equal sign and a numerical value on the left side. The left side of this definitional expression can be not only a symbol, but also a numerical value can be combined with this symbol by using a required operator. Then, when a line feed is performed after inputting the numerical value on the left side, the symbol is defined as a numerical value, and this definition formula is displayed on the display screen.
The symbolic expression uses at least one symbol that is already defined by the expression that defines the symbol, and inputs a numerical value or a symbol that is also already defined by combining the operator with the symbol. In addition, if you enter the equal sign of this symbolic expression and perform a line break, the arithmetic processing unit
After substituting the numerical value defined by the definition formula, arithmetic processing is performed and the arithmetic result is output to the display screen. Then, these input data are stored in the memory.

In executing the creation of a graphic, a graphic display area is set on the display screen and coordinates are set in the graphic display area. Then, a subcommand for drawing is displayed on the display screen, and in accordance with this subcommand, the drawing shape and various parameters at the time of drawing are input to create a figure. Here, when inputting parameters, the mathematical expression displayed on the display together with the graphic display area can be referred to. Then, although it is possible to input a numerical value, it is also possible to use a symbol defined by a definitional expression. When a symbol is used, this symbol is linked to the definitional expression and is represented in the figure by the numerical value defined by this symbol.

As described above, the calculation sheet is created by the calculation formula and the figure. The symbols used in the calculation formula and the figure are linked with the numerical values given by the definition formulas that define the symbol. There is. Here, the numerical value of the definition formula is variable, and if this numerical value is changed, the calculation result of the symbolic expression containing the symbol whose definition has been changed will change, so calculate again after substituting the newly defined numerical value. Is executed and the operation result is output to the right side of the symbolic expression. Also, along with this, the size and position specified by the symbol on the figure will change, so when you change the definition of the symbol, it will be reflected on the figure and displayed on the display screen. The existing graphic is changed to a graphic based on the newly defined numerical value. Therefore, it is not necessary to perform graphic processing again.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings. First, FIG. 1 illustrates an example of a layout prepared by partitioning a room having a predetermined space and providing a partition formed by the partition, as an example of a statement created by data processing.

Further, the formula F ₄ is a symbolic formula including a symbol on the left side and consisting of symbols and symbols or symbols, numerical values and operators. Here, the symbols included in the symbolic expression must be previously defined by the definitional expression. The right side is the result of the operation performed by substituting the numerical values defined by the definition formula.

On the display screen 1, the graphic is displayed in the graphic display area 3 so as not to overlap with the calculation expression display area 2.

It can be created by displaying a drawing subcommand on the display screen 1 and sequentially performing the necessary inputs to this subcommand. And when creating this figure,
As a matter of course, the calculation results of the calculation formulas simultaneously displayed on the display screen 1 are referred to, so that dimensions, positions, etc. can be input by the formulas including the symbols in the definition formulas or the symbols of the symbolic formulas.

The above statement can be created by using a data processing device such as a personal computer.
FIG. 2 shows a block configuration of each functional component in this data processing device.

In the figure, 10 is an input means,
This input means is composed of, for example, a keyboard and a mouse. An input control unit 11 receives an input signal from the input unit 10. Reference numeral 12 denotes a mode selection unit, which allows the user to select a work mode such as editing, graphic creation and setting, and printing by operating the input means 10.

Reference numeral 13 is an arithmetic processing unit, and 14 is a calculation formula processing file, and these form a calculation formula data processing unit 15. Then, when the edit mode is selected by the mode selection circuit 12, the calculation formula processing file 14 is opened, and when the input means 10 inputs a calculation formula according to a predetermined algorithm based on the calculation formula processing file 14, Predetermined arithmetic processing is performed in the arithmetic processing unit 13, and the calculation formula and the calculation result are displayed in a predetermined region of the display screen 1, that is, the calculation formula display region 2. Also,
A graphic processing unit 16 and a graphic processing file 17 form a graphic data processing unit 18. When the figure creation mode is selected by the mode selection circuit 12, the figure processing file 17 is opened, and the input processing is performed according to the predetermined algorithm defined in the figure processing file 17, so that the display screen 1 is first displayed. The figure display area 3 can be set, and when the figure display area 3 is set, the coordinate axes are displayed, the subcommand for drawing is displayed on the display screen 1, and the input means 1
By performing a predetermined input with 0, the graphic processing unit 1
Predetermined graphic processing is performed by 6 and the graphic is displayed on the display screen 1. Then, the data relating to the calculation formula and the data relating to the graphic created as described above are stored in the calculation formula cell and the graphic cell forming the memory 19.

Further, reference numeral 20 in the figure denotes a screen output section,
Calculation formulas and figures are displayed on the display screen 1 via the screen output unit 20. Reference numeral 21 is a control unit, and the control unit 21 controls the operation of the mode selection circuit 12, the signal processing unit 22 including the calculation formula data processing unit 15 and the graphic data processing unit 18, and the screen output unit 20. It is like this.

Here, the arithmetic processing unit 13 and the graphic processing unit 16
In and, among the calculation formulas created by the arithmetic processing unit 13, the definition formula for defining the symbol and the parameter for creating the graphic by the graphic processing unit 16 are linked. That is, the parameters of a predetermined size or position represented as a graphic are made by linking a symbol as a pointer with a definition formula, and when creating a graphic, the input for some or all of the parameters is defined. The symbols defined by the formula can be used, and when the numerical value of the definition formula is changed, the numerical value corresponding to the parameter in the figure is changed, and the size or position of the figure is changed.

Next, using FIG. 3 to FIG. 5, as a calculation sheet consisting of calculation formulas and figures by the above apparatus configuration, FIG.
The procedure for creating the calculation sheet shown in will be described.

First, when the personal computer is started up, as shown in FIG. 3, initial setting is performed (step 1) and a menu screen is displayed. Therefore, first, the calculation mode is selected (step 2). Then, in this calculation statement preparation mode, modes such as an edit mode (step 3) and a figure preparation mode (step 4) can be selected. When the edit mode is selected, editing such as creating or changing the calculation formula is executed (step 5), and when the figure creating mode is selected, a figure can be created (step 6).

When the edit mode is selected, a calculation formula can be created as shown in FIG. 4, and when the graphic creation mode is selected, a graphic can be created as shown in FIG. Then, the preparation of the calculation sheet is completed. Further, when the calculation sheet is created and then corrected, the edit mode can be returned to and the correction can be performed by the procedure shown in FIG.

Here, in creating the calculation formula, a numerical value, an operator, and a symbol (for example, alphabet) can be used as the input means 10 by using a keyboard. When there is an input from the input means 10 (step 1
0), first, it is judged whether or not it is a new input (step 1
1) If it is a new input, whether the input is a numerical value (step 12), whether it is a symbol (step 13), whether it is an operator (step 14), and A determination is made as to whether it is a relational child, that is, an equal sign (step 15).

When numerical values, symbols and operators are input,
These are held at a predetermined address in the calculation formula cell forming the memory 19 (steps 16 to 18) and sequentially displayed on the display screen 1. When the equal sign is input, the left side of the calculation formula is determined, and it is determined whether or not a line break has occurred (step 19). Then, when a line feed is made, it is determined whether or not a symbol is included on the left side (step 20). If no symbol is included, it is recognized as a numerical expression and the operation of this numerical expression is performed (step 21). ). If the symbol is included, it is judged whether or not this symbol is already defined (step 22). If the symbol is defined, it is recognized as a symbolic expression and is defined by the symbol. If a numerical value is substituted and the operation is performed (step 23) and the symbol is not defined,
When the display screen 1 indicates that it is undefined (step 24) and a predetermined clear key is operated,
The input of this expression becomes invalid (step 25). Immediately after the equal sign is input, line feed is not performed immediately, and when a key operation other than line feed is performed, it is determined whether the input is a numerical value (step 26). Here, the input other than the numerical value is invalid after the line feed, and when the numerical value is input and the line feed is continued, it is recognized as the definition expression and it is judged whether this symbol is already defined or not. Is performed (step 27), and if it is undefined, it is registered as a definitional expression (step 28). If it is already defined, it is displayed on the display screen 1 that it is a duplicate definition (step 29), and when a predetermined clear key is operated,
The input of this expression becomes invalid (step 30). And
The above work is continued until the mode conversion is performed (step 31), and when the mode conversion is performed, the calculation formula is fixed.

When each calculation formula is determined, the calculation formula cell in the memory stores each calculation formula and its type, that is, the type of numerical formula, definition formula, or symbolic formula. It Here, the numerical formula is a fixed calculation formula, the right side of the definition formula is variable, and the right side of the symbolic formula follows the right side of the definition formula, that is, when the defined numerical value is changed. Change, in other words,
The symbolic expression is linked to the definitional expression using the symbol as a pointer. Therefore, on the display screen 1, it is discriminated whether the type of each calculation formula is the one on which the numerical value on the right side is fixed, the changeable numerical value, or the numerical value that changes according to the change of the definitional expression. In order to make it possible, it is preferable to adopt a display mode such as coloring or surrounding with a frame of a predetermined color.

Specifically, in the calculation formulas F _{1 to} F ₄ of FIG. 1, the input is made in the order shown in FIG. 6 by the keyboard operation. First, as the calculation formula F ₁ , the keys of the numerical value “5”, the operator “+”, the numerical value “7”, and the equal sign “=” are sequentially input, and when the line feed key is operated, 5 and 7 are obtained. An operation is performed on the product of and the operation result "35" is output. Further, the calculation formulas F ₂ and F ₃ are definition formulas, and the keys of the symbols “a” and the equal sign “=”, the symbols “b” and the equal sign “=”, and the numerical values “2” and “3” are input. Then, when a line feed is performed, a is defined as 2 and b is defined as 3. Further, the calculation formula F ₄ is such that when the symbol “a”, the multiplication symbol “×”, the symbol “b”, and the equal sign “=” are input and the line feed key is operated, this calculation formula becomes Since it is an expression,
After the previously defined a = 2 and b = 3 are substituted, a 2 × 3 calculation is performed, and 6 which is the calculation result is output.

Each of these calculation formulas F _{1 to} F ₄ is the calculation formula F ₁
Is the area of the entire room C, the display of “room area” is shown, and the calculation formulas F _{2 to} F ₄ are related to the partition section P by the partition, so the display of “partition” and the calculation formula F ₂ "vertical" for "horizontal" for formula F _3, further for formula F ₄ may be displayed before the display of "area" of the respective formula.

Next, when the figure creation mode is selected, as shown in FIG. 5, the area is set first (step 40). For setting this area, display screen 1
In, the cursor is operated using the input means 10, and as shown in FIG. 7, by inputting a predetermined position on the display screen 1 as the start point position SP and by inputting another point as the end point position FP. The graphic display area is set accordingly. Then
By inputting the coordinate origin position O, an XY Cartesian coordinate axis centering on the coordinate origin 0 is set, and this coordinate is displayed on the display screen 1 (step 4).
1). When the above preparations have been made, drawing type subcommands are displayed on the display screen 1 (step 4
2) The state of the figure to be created can be selected. A type of figure, for example, a quadrangle, is selected from the drawing type subcommands (step 43). Then, when a quadrangle is selected, the figure creation subcommand on the display screen 1 is displayed (step 44). Here, as shown in FIG. 8, in order to create a quadrangle, the coordinates (x, y) of the starting point position and parameters relating to the vertical and horizontal dimensions are input (step 45). In FIG. 1, the overall shape of the room C is 5 in the vertical direction and 7 in the horizontal direction. Therefore, as the starting point coordinate position (x, y), (0, 0) to a predetermined position is input, and the vertical direction is set to 5. Further, if 7 is input to the side and selection is made (step 46), the graphic is confirmed and displayed on the display screen 1.

Next, the partition P by the partition is created in the same manner. However, regarding the parameters in the figure creation subcommand for forming the partition P,
As the coordinates of the starting point position, for example, (1, 2) is input, but a is input vertically and b is input horizontally. As a result, the starting point position of the room C is determined by the input, but the vertical and horizontal dimensions are represented by the symbols a and b. When creating the calculation formula, this symbol a, b is defined. Therefore, this numerical value is applied to the figure, and a 2 × 3 quadrangle figure based on the starting point coordinate position (1, 2) is created on the display screen 1.

For this reason, when the parameter shown in the figure creation command is input to input that the figure is fixed, it is determined whether the input is a numerical value or a symbol (step 47), if it is a number,
A graphic based on the numerical value is displayed (step 48),
If the symbol is input, it is first determined whether or not this symbol is defined (step 49). If it is defined, the numerical value of the symbol is read from the formula cell in the memory 19. Then, the symbol is converted into a numerical value (step 50), and then the figure is displayed (step 5).
1). If the symbol is not defined by the definition formula, a message indicating that it is undefined is displayed, the selection is cleared, and the parameter is held in a state in which change input is possible (step 5).
2). When one figure is confirmed, a command output as to whether or not to create another figure is performed (step 53). When creating another figure, the drawing type subcommand is displayed again, and so on. If a figure can be created and no other figure is created, the figure creation process ends.

The figures are created as described above, and the data relating to these figures are stored in the figure cells in the memory 19. Then, of the data stored in this graphic cell, the vertical and horizontal dimensions of the partition portion P are the symbols a,
It is linked to the definitional expression using b as a pointer.

The operation of changing the size and shape of the partition P after the statement is created once as described above can be performed by the procedure of FIG. That is, in the edit mode, the numerical value on the right side of the calculation formula F ₂ or F ₃ can be changed. Therefore, if there is a change input, it is judged whether or not the change input is a change in the definition of the symbol (step 60), and if it is a change other than the definition of the symbol, an error is displayed (step 61). If the definition of the symbol is changed, the numerical value stored as the definition of the symbol in the calculation formula cell of the memory 19 is changed (step 6).
2). When the change in the definition of this symbol is confirmed (step 63), it is determined whether or not this symbol is included in the symbolic expression (step 64), and if it is included, the recalculation is performed. The calculation result is displayed on the right side of the symbolic expression (step 65). At the same time, it is determined whether or not a symbol is included in the parameters relating to the dimensions of the figure (step 66), and if it is included, the dimensions of the relevant part in the figure are changed. By doing so, the change in the definition of the symbol is reflected in the graphic (step 67).

As described above, when the numerical value of the calculation formula is changed by linking the calculation formula and the graphic with the symbol as a pointer, the numerical value is reflected in the graphic and the graphic corresponding to the changed numerical value is automatically obtained. Is changed to. Therefore, it is not necessary to input the figure again. Here, the vertical and horizontal dimensions of the partition P are made variable, but, for example, if the starting point coordinate position is also made variable, that is, the starting point coordinate position OP = (c, d), and c
If the definitional expressions for and are set, the partition P can be moved to an arbitrary position by changing the numerical values of c and d.

Further, for example, as shown in FIG.
When creating a figure in which a partition P is provided inside and a circular table T is arranged in this partition P, as a mathematical expression, the coordinate position TC = of the center of the circle of the table T =
(E, f) and e, f and the radius r are defined (eg, e = 1, f = 2, r = 0.5), and the graphic creation subcommand for the circle is displayed on the display screen 1. When the symbols are input with symbols e, f, and r when displayed in, the circle of the position and shape according to the definition is displayed, and if these symbols e, f, and r are changed, the circles are changed accordingly. The shape also changes.

[0032]

Since the present invention is configured as described above, when a calculation statement including a figure and a calculation formula is created by data processing, when the value of the calculation formula is changed, it is reflected on the graphic. By doing so, there is an effect that the figure can be changed according to the numerical value thereof.
