Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a design procedure support device that supports, for example, a vehicle design procedure.

(Prior Art) Conventionally, in order to support the design of the above-mentioned vehicles, high-grade FiUI has been developed.
For example, there is a program using Fortran. Using this program, design concepts (concepts),
For example, the design is supported by inputting data into the O-400 start program.

When a design change occurs during the O-400 start-up process during the design support process, the user redesigns the flowchart and performs a so-called depack to test the execution of the program after programming. However, the series of operations from the above flowchart to depacking requires time and effort.
This caused a delay in the processing time of design support.

As a countermeasure against this, a frame is a combination of heading information consisting of information necessary for design, and sub-information consisting of data values necessary to obtain this heading information, related information, relational expressions, etc. Build vehicle design. This system supports vehicle design by using many of the frames mentioned above.

(Problems to be Solved by the Invention) Conventional devices use a large number of frames to support design, so the relationships among the frames are complicated. In particular, users with little experience in vehicle design have trouble understanding the relationships between the frames. This may result in delays in understanding the relationships and supporting design. Furthermore, if a design change occurs during design support, it is difficult for the user to understand which frame should input the change data in order to achieve the optimal vehicle design, since a large number of frames are used to design the vehicle. For this reason, the user feels troublesome to operate the design procedure, and a countermeasure for this problem has been desperately needed.

This invention has been made in view of the above, and its purpose is to reduce the complexity of operations that support various design procedures, and to provide an efficient and flexible design procedure support device. be.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the present invention provides information including information necessary for design and data values, related information, and relational expressions necessary to obtain the information. a first information storage means 1 which stores a plurality of combinations of heading information and sub information, respectively; a second information storage means 3 which stores data of design results of past designs; and desired heading information to be obtained. a search means 5 for searching the second information storage means 3 for data corresponding to sub-information to be combined with the heading information and other heading information for determining the heading information when the heading information is selected; 5, the data retrieved from the second information storage means 3 is used to perform calculations based on relational expressions, etc. of the heading information and other heading information of the first information storage means 1, and the input information of the searching means 5 is calculated. The present invention has the following features: construction means 7 for constructing desired heading information to be obtained and values of other heading information for determining the heading information.

(Operation) In the design procedure support device having the above configuration, when the desired heading information to be obtained is input, necessary information of the sub-information to be combined with the heading information and data necessary to obtain the said information are provided. is searched from the second information storage means 3 that stores data of design results designed in the past.

The retrieved data is calculated using a relational expression of the heading information of the first information storage means 1 and other heading information for determining the heading information, and the values of the desired heading information and other heading information are re-calculated. This allows efficient and flexible design.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 is a block diagram of the configuration of an embodiment of the design procedure support device of the present invention.

The design procedure support device includes an input section 212, a display section 23, a data storage section 25. It has a design knowledge group storage section 27 and a knowledge control section 29.

The input unit 21 includes a keyboard 21 for inputting desired information necessary for design, which is output data desired by the user of the apparatus, and other information.

The display unit 23 displays data, parameters, calculated output data, etc. that must be further input by the user and determined during the design support operation to calculate output data, and is stored in the data storage unit 25. It consists of a display device that displays reference values, which will be described later.

The data storage unit 25 stores so-called reference values such as output data of past vehicle design results in a file format.

The design knowledge group storage unit 27 stores procedural knowledge of the design J1, specifically, output information desired by the user, heading information consisting of information necessary for design, and data values necessary to obtain the heading information. A plurality of combinations of sub-information including related information, relational expressions, etc. are stored.

The knowledge control unit 29 searches the design knowledge group storage unit 27 for heading information such as desired output data and design S1 information inputted from the input unit 21 and obtains sub-information for the heading information, and also acquires sub-information for the heading information. When there is no value of the sub information and the undetermined sub information is information that can be input from the input section 21, control is performed to input the undetermined sub information from the input section 21. Furthermore, when the obtained sub-information is unconfirmed and this unconfirmed information is not information that can be input from the input section 21, the knowledge control section 29
Until all of this undetermined sub-information is determined, the undetermined sub-information is used as header information, and the sub-information corresponding to the header information is retrieved from the design knowledge group storage unit 27, and all the sub-information and The output data for the desired heading information input from the input section 21 is obtained based on the relational expression.

Further, the knowledge control unit 29 reads reference values, which are data values necessary for the sub information of each frame used in vehicle design in the past, from the data storage unit 25, and sets parameters indicating heading information into which the read reference values are taken. When selected, the relevant parameter is imported into the lowest layer parameter, which is the lowest layer to be determined (import parameter). The knowledge control unit 29 calculates the relational expression of the lowest layer parameter and searches the design knowledge group storage unit 27h1 for the value of the calculation result, a parameter determined by the so-called output parameter. When the search for the affected parameters is completed, the knowledge control unit 29 imports the reference value into the lowest layer parameter and resets all the affected parameters.

FIG. 3 shows various frames 31 consisting of combinations of heading information and sub information stored in the design knowledge group storage section 27. As shown in the figure, the heading information and the sub information related to the heading information that are combined and stored in the design knowledge group storage unit 27 are stored in a frame (Flame).
) according to the description.

In other words, "A" is shown as design information that is one of the vehicle performance that the user wants, for example, "0-400m acceleration" is shown, but in this frame, the top column contains heading information. rAJ)” 1aI
e, and sub information related to the heading information rAJ is shown in the column below this. For example, as shown in the figure, this sub-information includes output, input,
put ) and an expression (siki).

n] The output in the information is the heading information r
The output value for AJ and the output parameters described above are shown. In this case, for this output (output), it is written as ``<value) 1f-needed 5ikiJ'', and if a value is required, calculate the formula (siki). Note that evaluating something written in a mathematical formula in this way is called starting a daemon.

Further, input in the sub information describes essential information to be input when calculating rAJ, and this input information includes rBbJrccJ. Further, the formula (5iki) describes the formula (b + c) for calculating rAJ using each of the input information.

In addition, the input information described in the above-mentioned frame input (input) includes information input from the input section 21 and information obtained from the design knowledge group storage section 27 using this input information as heading information. be. Input information that needs to be input from the former input section 21 is displayed to the user via the display section 23, and the user views this display and inputs data for the input information. .

Further, the input information obtained from the design knowledge group storage unit 27 as the latter heading information is, for example, rb shown in FIG.
J, "C", so-called input parameters, etc., and rbJ is the information described in the input of the frame in FIG. 3, but this input information rbJ is input immediately from the input section 21 Rather than being given, the knowledge control section 27 searches for a frame stored in the design knowledge group storage section 27 as a frame as shown in FIG.

That is, to obtain the output value for the heading information rAJ shown in FIG. 3, input (1nput) of the information rAJ.
It is necessary to obtain information such as rBJ, "C", etc., but in order to obtain these information, it is necessary to
), it is now necessary to search for knowledge frames in a hierarchical manner. FIG. 4 shows the hierarchical structure of such knowledge frames. In the same figure, "rA, J, and K" indicate the topmost information, rB, CJ below it indicate information such as rBJ, rCJ, and the bottom "G.

H and IJ indicate the lowest information. In the layering of information constituting such a knowledge frame, each piece of information is sequentially determined according to the layer.

For example, in the example of the parameter relationship shown in FIG. 4, parameter C can be determined by determining the values of parameters E and F, and E can be determined by determining the values of parameters H and I.

Here, F,)(,I is the lowest layer parameter which is the lowest information.E is the parameter that is influenced by the lowest layer parameter H11, and similarly, C is also E,
The affected parameter is determined by F.

FIG. 5 shows the design knowledge group storage unit 2 displayed on the display unit 23.
7 shows an example of current design values stored in No. 7 and reference values that are optimal values used in vehicle design in the past. When the above reference value is displayed on the display unit 23, the user can:
For example, if the parameter C1 reference value "10" shown in FIG. Becomes 11th state. After the n1ll state, the two knowledge control units import reference values into the lowest layer parameters F, H, and I, calculate an influence parameter E using the imported reference values, and set C.

Next, the operation of this embodiment will be explained in Figs. 6 and 7 (a) to ().
This will be explained using the process flow chart C).

First, after turning on the power to the device, the knowledge control section 29
Display processing items. If the user specifies an item for vehicle design from the processing items on the display section 23 as a design concept from the input section 21, for example frame 1 at O-400 start, the process proceeds to step 110; If the design is changed using the value, the process proceeds to step 200. Furthermore, if you want to read reference value data, step 30
0, and if the designed data is to be stored in a file after the design is completed, proceed to step 400 (step 100).
.

, when the frame i is specified in step 110, the knowledge control unit 29 selects O to 400 from the design knowledge group storage unit 27.
Search for frame i at the time of departure.

When this frame 1 is searched, the knowledge control unit 29 checks whether there is an output value for the heading information rAJ from the sub information of this frame 1, and if there is an output value, outputs the output value (step 110 ~120,180).

When there is no output value for the above frame i, the knowledge control unit 2
Step 9 determines whether or not this output value should be input by the user based on the description of the 01 information (step 130), and if the output value is to be input by the user, the display section 23 indicates the fact. The output value is displayed and notified to the user, and the user inputs the output value through the input unit 21 to obtain the output value (step 140.180>).

On the other hand, if it is not input by the user in step 130, "output: f-" in the sub information
The daemon will be started and calculations will be made from 5iki as shown in "needed 5ikiJ", but in this case, it is first necessary to obtain each input necessary for this 5iki. Therefore, the knowledge control unit 29 searches the design knowledge group storage unit 27 for information, that is, knowledge, for each input of the sub information of the frame.
The relation of the frame 31 shown in FIG. 3 is turned on and stored in the design knowledge group storage unit 27 (step 150
．． 160).

The above inputs include, for example, rbJ, r
CJ, etc., each frame with each of these inputs (1nput) as heading information is sequentially searched from the design knowledge group storage unit 27, and the searched frame is similarly inputted (input).
If there is a put), the same search process is repeated to find the value for each input (input) until all values are found (step 160).

Specifically, the case of determining the value of rBJ will be explained with reference to FIG. 3. The input (in
In order to find the value for rBJ, which is (put), it is necessary to find a frame that uses this rBJ as heading information. and do it. on the other hand,
1f-neede (dll-db), the knowledge control unit 29 searches from the di-db database described below this frame.

Similarly, all inputs (
When the value of 1nput ) is determined, all the determined input values are applied to the equation (b + c), and the output value for rAJ is determined from this equation,
It is output (steps 170-180).

On the other hand, when the process proceeds to step 200 in which the design is changed using the reference values, the knowledge control section 29 searches the data storage section 25 to see if the reference values are stored. Reference value is data storage unit 2
If the reference value is not stored in the data storage unit 25, the knowledge control unit 29 will
The parameter name, current design value, and reference value are displayed on the display section 23 (steps 200 to 210).

When a reference value is displayed on the display section 23, the user specifies a parameter, for example, parameter C, for which the reference value is to be used, if it is a reference value to be incorporated into a design change among the displayed reference values, from the input section 21. . When a parameter is selected, the two knowledge control units retrieve, for example, the lowest layer parameters F, H, and I for the selected parameter C from the design knowledge group storage unit 27. Further, the two knowledge control units search for a parameter E and a top layer parameter C that are influenced when the values of the searched lowest layer parameters F, H, and I are determined. When the affected parameter E and the lowest layer parameters F, H, and I are searched, the two knowledge control units display the display unit 2.
Parameter E1 affected by 3. Bottom layer parameters F, H
, I and the current design value (step 220~
25o).

When the lowest layer parameters F and the like are displayed on the display unit 23, the user presses the end key to end the process unless the reference value is incorporated into the highest layer parameter C. On the other hand, if a reference value is to be taken into the top layer parameter C, the user presses the corresponding key. When the relevant key is pressed, the knowledge control unit 29 puts all of the affected parameters C and E into an undetermined state. When the undetermined state is reached, the knowledge control unit 29 imports reference values into the lowest layer parameters F, H, and I, activates the highest layer parameter C, and calculates the value of the affected parameter E, thereby determining the value of the design change. Calculated (Step 2
60-290).

Proceeding to step 300, the knowledge control section 29 searches the data storage section 25 for the file name and concept sentence of the file storing the reference value, and displays them on the display section 23.

When the file name etc. are displayed, the user inputs the file name to be imported using the input section 21. Upon input of the file name, the knowledge control unit 29 searches the input file from the data storage unit 25 and reads the reference value (step 300
~320).

Proceeding to step 400, if the design change has been completed, the user inputs a file name from the input section 21 in order to register the design S1 in the file.

When the file name is input, the knowledge il'i++ control unit 29 stores the file with the input file name at a predetermined address in the data storage unit 25 (steps 400 to 420).
.

As a result, even when changing the design, the user can support the design by incorporating reference values, without feeling the need for complicated operations.

This embodiment is applicable not only to vehicle design but also to support various design procedures.

[Effect of the Invention 1 As explained above, according to the present invention, the relationship between necessary information used in past designs, desired heading information during design, and other heading information for determining the heading information is Since values are constructed by calculations using formulas, etc., the complexity of operations supporting various design procedures can be reduced, and design support can be speeded up.
