Description

Description: TECHNICAL FIELD The present invention relates to a layout design support device in which execution intelligence (AI) is applied to layout design and the like.

(Technical background of the invention and its problems) In recent years, so-called artificial intelligence is being developed in which a computer is provided with an inference function for inputting a certain phenomenon to retrieve a causal relationship and infer the cause. And, among those that use this artificial intelligence in various fields, there is CAD (Computer Aided Design) that uses a computer for design. FIG. 5 is a block diagram of such a conventional layout design support device.

First, it is composed of, for example, a graphic screen not shown
For example, various menus related to vehicle installation design are displayed on the CRT, and the user selects, for example, the layout design near the driver's seat from the menu, and an input device (keyboard) not shown
While pressing the corresponding key, enter the driver's eye point, roof, steering wheel, access and other components. The input components are stored in the storage device A21. Also,
Each component is stored in advance in the storage device B23 as a reference design of a vehicle layout design in a so-called temporary layout state (temporary coordinate value is determined) in the area of the graphic screen.
Then, the search device 27 reads the temporary placement corresponding to the component input by the user from the storage device B23, and detects whether or not the temporarily placed component is applied to the placement condition which is the design specification of the user. If all the components that are provisionally arranged according to the detection result satisfy the arrangement conditions, the state of the temporary arrangement is displayed on the CRT and the arrangement design ends. On the other hand, if a component that does not satisfy the placement condition is detected, the search device 27
The state of the temporary arrangement is displayed on and the calculation command signal is output to the calculation device 29. When the calculation command signal is input, the calculation device 29 performs the calculation by applying the movement rule of FIG. 6 to the constituent elements that do not satisfy the arrangement condition. If there is a constituent element to which this movement rule cannot be applied, the arrangement and movement of this constituent element becomes impossible, so the arrangement design cannot be completed and the processing ends.

Here, the movement rule is, for example, in the IF statement for the component E (accelerator pedal), the accelerator pedal is arranged below the Y coordinate of the component F (roof), and the distance between the accelerator pedal and the roof is If it is 10 dots (pixels) or more, set the accelerator pedal shown in the THEN sentence to 2 dots Y
It moves downward with respect to the coordinates. Based on this movement restriction, the arithmetic arrangement 29 performs an arithmetic operation to move a constituent element that does not satisfy the arrangement condition, and stores the state of the temporary arrangement of the constituent element in the storage device B23.

The layout design support is performed by repeating the above processing.

By the way, in the conventional installation design support device, the preliminarily stored temporary layout is moved in the direction satisfying the layout condition based on the movement regulation to support the layout design.

However, in such an arrangement design support device, since the temporary arrangement is predetermined as the reference design,
It is necessary to set the coordinate value of the temporary placement for all the components, and it takes a lot of work from the temporary placement to the completion of the layout design, and there is a problem that it is not efficient, and there is a need for improvement. It had been.

(Object of the Invention) The present invention has been made in view of the above, and an object thereof is to provide a layout design which can efficiently support layout design without inputting coordinate values of all components. To provide a design support device.

(Summary of the Invention) In order to achieve the above object, the present invention provides an initial condition input means for inputting a name of a component to be layout-designed and a layout condition between the component and other components, and inputting means. Detecting a component having no coordinate value from among the detected components, and using other components determined from the arrangement condition of the detected component, from among the detected components A constituent element detecting means for detecting a constituent element capable of calculating the coordinate value, and a constituent element capable of calculating the detected coordinate value among coordinate determination rules stored in advance in association with the constituent element. Rule selecting means for selecting a rule to be used, a calculating means for calculating the coordinate value of the component based on the selected coordinate determination rule, and an arrangement in which the calculated coordinate value of the component is input as the initial condition. Meet the conditions It is determined whether or not to perform, and if they do not match, a changing unit that changes the coordinate value of the component based on a movement rule stored in advance is included.

(Embodiment of the Invention) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In the figure, a CRT 19 which is a terminal unit is, for example, a graphic screen of three-dimensional coordinates in which a screen area is composed of dots (pixels), and a layout design and various messages regarding a vehicle are displayed. The input device 17 is composed of a keyboard and the like, and is used when the user inputs a coordinate point name, a coordinate value of a component, a distance indicating an arrangement condition between coordinate points, an angle, and the like.

The data storage 7 stores the coordinate point name, coordinate value, distance indicating the arrangement condition between the coordinate points, angle, etc. of the component input by the user as shown in FIG.

FIG. 2 shows an example of data stored for designing the layout of the clutch pedal (hereinafter also referred to as C / P).

Here, the stepping position in FIG. 2 is the input value of the three-dimensional coordinates from the user, and the C / P stroke indicates the distance data. The input value from the user or the calculation unit 15 described later.
The calculated value in (4) and the value indicating the allowable value that can be calculated with respect to the input value of the user are stored. The C / P initial position indicates the reference coordinate value of the temporary arrangement of each component.

That is, in FIG. 2, the first "data-d" is C /
The entered three-dimensional coordinate value of the stepping position of P is (500,100,20
0).

The second "data-d" indicates that the three-dimensional coordinate position of the initial position of C / P is unknown (value obtained from this).

In the third "data-d", the C / P stroke is represented by "100" which is the set value (input value) of the distance data, or the calculated value of the distance data, and its allowable value (this is the placement condition). It is "95 to 110".

The inference rule storage unit 9 defines a rule that defines a placement condition between coordinate points of each component by distance and angle (this is called a distance definition rule), and a rule that determines a temporary placement using the rule (this is a coordinate The decision rule) is memorized.
Specific rules are shown in FIGS. 3-a and 3-b.

That is, in FIG. 3-a, "rule-c" is the distance definition rule, and the first "rule-c" is the C / P in which the initial position of C / P is set in advance as a reference value. It shows that it is determined from the fulcrum and the C / P lever length, which is the distance calculated from the C / P fulcrum by calculation. The number of blood at the end of the rule indicates its serial number.

The second "rule-c" is the C / P step position where the initial position of the C / P is the user input and the C / P stroke that is the distance data input by the user from the C / P step position. It is shown that it is determined by the length.

Also, "rule" in Fig. 3-a is a coordinate determination rule that determines the coordinate value of each component using the above distance definition rule. The first "rule" is the initial position of C / P. It means that it is determined by the rule of serial number 1 and the same number 2 of "rule-c".

The second "rule" means that the initial position of the C / P is also determined by the rules of serial numbers 1 and 3 (not shown) of "rule-c".

That is, when the user selects the first “rule”, as shown in FIG. 3-b, “draw with the distance of the C / P lever length centering on the C / P fulcrum of the distance definition rule”. A curve,
The intersection with the curve drawn with the distance of the C / P stroke length centered on the C / P stepped position is determined as the coordinates of the C / P initial position. The rule "" applies. It should be noted that these rules are stored in correspondence with each component.

The movement rule storage unit 11 stores the movement rules in FIG. 6 described above, and is used to move the constituent elements in a direction suitable for the arrangement condition after the temporary arrangement of the respective constituent elements is completed.

The search unit 13 stores the coordinate point name, distance data, etc. of each constituent element input by the user from the input device 17 in the data storage unit 7 and applies it to determine the temporary placement from the inference rule storage unit 9. Search the distance definition rule and the coordinate determination rule described above. Further, the search unit 13 checks whether or not the distance data or the like input by the user can be calculated with reference to the searched distance definition rule and coordinate determination rule, and if the calculation is possible, sends a command signal to the calculation unit 15. Output and apply the rule to search whether the placement conditions are met, and
The state of temporary arrangement is displayed at T19.

When the command signal is input from the search unit 13, the calculation unit 15 calculates the distance data of the constituent elements and the coordinate value according to the coordinate determination rule, and stores the calculation result in the data storage unit 7.

Next, the operation of this embodiment will be described with reference to the processing flowchart of FIG.

First, for example, the CRT19 which is composed of a graphic screen
For example, various menus relating to the vehicle layout design are displayed, and the user selects, for example, the layout design near the driver's seat from the menu and presses the relevant key of the input device 17 (keyboard) to drive the components necessary for the temporary layout. After inputting coordinate point names such as the user's eye point, roof, steering wheel, accelerator, etc., input coordinate values such as the eye point of the component, distance indicating the arrangement condition between coordinate points, angle, etc. (step 100). . In the example of FIG. 2, among the layout designs near the driver's seat, the data related to the layout design of the clutch pedal are the C / P stepped position, the C / P initial position, the C / P stroke, etc. as input data.

When the input from the user is completed, the search unit 13 stores the data such as the input distance (in the example of FIG. 2, C / P stepping position, C / P initial position, C / P stroke, etc.). The data is stored in the unit 7 and is searched for whether the data can be calculated.
Is displayed in step 130 and the process proceeds to step 130, and if calculation is not possible, the process returns to step 100 and re-input (steps 110 to 12)
0). That is, in the case of the arrangement of the clutch pedal, the coordinates of the C / P initial position are unknown, but the coordinates and distances of other components such as the C / P stepped position and the C / P stroke have already been set. Since the distance definition rule regarding the C / P initial position is set, it is determined that the coordinates of the C / P initial position can be calculated.

When the process proceeds to step 130, the user presses the relevant key for the coordinate point displayed on the CRT 19 if it is adopted in the layout design and proceeds to step 140.
Return to step 130.

Upon proceeding to step 140, the retrieval unit 13 displays on the CRT 19 one or more coordinate determination rules applicable to determine the coordinate value of the coordinate point from the inference rule storage unit 9. If there is a rule to apply among the displayed coordinate determination rules, the user presses the key to proceed to step 106, and if there is no rule to apply, presses the key to proceed to step 260 (step 140).
~ 150). In the case of the clutch pedal arrangement, the 3-a
The coordinate determination rule shown in the figure is displayed, and the user selects a desired rule from these.

When the process proceeds to step 260, "Do you want to decide another coordinate point first?" Is displayed on the CRT 19, and if the user decides another coordinate point first, press the corresponding key and return to step 120,
On the other hand, if not decided first, the process returns to step 100.

On the other hand, when the process proceeds to step 160, the search unit 13 outputs a command signal to the calculation unit 15, and the calculation unit 15 calculates the C / P initial position of the coordinate point using the selected coordinate determination rule. If so, the process proceeds to step 180, and if an imaginary number solution or the like is calculated by the calculation result, the process proceeds to step 270, and if another coordinate determination rule displayed on the CRT 19 is used for calculation, the process proceeds to step 140 and the rule is changed. If it is not used, the process proceeds to step 260 and the coordinate point is selected (steps 160, 170, 27).
0).

When the process proceeds to step 180, the search unit 13 returns to step 110 to search for the coordinate points that can be calculated if the placement of the coordinate points for the layout design is not completed, and if the placement is completed, the search unit 13 proceeds to step 190 (step 180). In this way, the layout design near the driver's seat other than the layout design of the clutch pedal is sequentially performed.

When the processing proceeds to step 190, the calculation unit 15 calculates the distance and angle representing the arrangement condition between the arranged coordinate points, the temporary arrangement is completed, and the temporary arrangement near the driver's seat is displayed on the CRT 19 (step 190). .

When the temporary placement near the driver's seat is displayed on the CRT 19, if all the constituent elements of the temporary placement satisfy the placement conditions by the user, the process proceeds to step 210 and the layout design ends, and among the constituent elements of the temporary placement, for example, If the coordinate of the eye point is different from the arrangement condition, the corresponding key for moving the coordinate of the eye point is pressed and the process proceeds to step 230 (steps 200 to 210).

When the process proceeds to step 220, the search unit 13 searches the move rule storage unit 11 for a move rule for moving the coordinates of the eye point that is different from the above-mentioned arrangement condition. Step 2 if there are rules
Proceed to 30.

When the process proceeds to step 230, the calculation unit 15 moves each component while performing the calculation of the movement process based on the movement rule, and proceeds to step 200 (steps 220 to 230).

On the other hand, when the process proceeds to step 240, the search unit 13 proceeds to step 220 if it can search whether or not the conditions other than the above-mentioned roof, such as the handle, are satisfied, and detects the corresponding movement rule. It becomes impossible and ends (steps 240 to 250).

As a result, temporary placement is performed according to the rules that are appropriate for the components input by the user, so that temporary placement is automatically executed based on the coordinate determination rules without setting and inputting coordinate values for all components. Therefore, the layout design can be performed efficiently. The annoyance associated with this type of layout design can be reduced.

(Effects of the Invention) According to the present invention as described above, provisional placement is performed according to a rule suitable for a component input by a user, so that coordinate values need not be set and input for all components. The temporary placement can be automatically executed based on the decision rule, and the placement design can be performed efficiently.
