Abstract

PURPOSE:To efficiently support arrangement and designing by setting a temporary arrangement based on arrangement requirements. CONSTITUTION:Judging from the way that plural constituents are temporarily arranged, an arranging and designing device arranges and designs the constituents in a set area based on arrangement requirements regarding the relative position relation between the constituents. Said device has an extrapolation rule storage means recording extrapolation rules which extrapolates the process from arranging to designing based on the host of arrangement requirements, a constituent input means 1 which inputs the constituents required for building up the temporary arrangement and designing and their setting conditions, and an arithmetic means 5 which calculates in order to build up the temporary arrangement and designing for the constituents from the constituent input means 1, judging from the extrapolation rules of the extrapolation rule storage means 3 and the conditions to set the constituents. Thus the temporary arrangement is set based on the arrangement requirements, whereby the arrangement and designing are efficiently supported.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a layout design support device that applies artificial intelligence (AI) to layout design and the like.

(Technical background of the invention and its problems) In recent years, progress has been made in the development of so-called artificial intelligence, which has an inference function that inputs certain causes into a computer, searches for causal relationships, and infers causes. Although this artificial intelligence is used in various fields, computer use in design, or CA D (Computer A
1dedQsign).

FIG. 6 is a block diagram of such a conventional layout design support device.

First, various menus related to the layout design of the vehicle are displayed on a CRT (not shown), for example, which is configured with a graphic screen, and the user selects, for example, the layout design near the driver's seat from the menu, and selects the layout design near the driver's seat from the menu. Press the appropriate key on the (keyboard) and the driver's eye point,
Enter components such as roof, steering wheel, accelerator, etc.

The input components are stored in the storage device A21. Further, each component is stored in advance in the storage device B23 in a so-called temporary layout within the area of the graphic screen as a standard design for the layout design of the vehicle. Then, the search device 27 stores the temporary layout corresponding to the component input by the user in the storage device 8.
23, and detects whether or not the temporarily arranged component applies to the user's design specifications, so-called arrangement conditions. If all the components satisfy the placement condition according to the detection result, then C
The state of the temporary arrangement is displayed on RT, and the arrangement film δ1 ends.

On the other hand, when a component that does not satisfy the placement conditions is detected, the search device 27 causes the CRT to display the state of the temporary placement and outputs a calculation command signal to the calculation device 29. When the calculation command signal is input, the operation D device 29 performs the calculation if the movement rule of FIG. 7 is applied to the component that does not satisfy the placement condition, and if the movement rule of FIG. As a result, the layout design cannot be completed and the process ends.

Here, the movement rule is an IF statement for component E (accelerator pedal), where the accelerator pedal is placed below the Y coordinate of component F (roof), and the distance between the accelerator pedal and the roof is 10 dots. (pixels) or more, press the accelerator pedal indicated in the THEN statement by pressing 2 dots Y.
It moves downward relative to the coordinates.

Based on this movement restriction, the processing device 29 performs calculations, moves the component that does not satisfy the placement condition, and stores the temporary placement state of the component in the storage device B23.

Layout design support is performed while repeating the above processing.

By the way, in a conventional installation design support device, placement design support is performed by moving a pre-stored temporary layout in a direction that satisfies the placement conditions based on movement restrictions.

However, in such a layout design support device, the temporary layout is predetermined as a reference design, so as the layout design becomes more complex, it is necessary to store many movement rules in the storage device C25. In addition, in the case of design changes, the user must calculate the distances, angles, etc. between the components and temporarily arrange them in order to set the components at arbitrary coordinates, so it is difficult to design the layout from the temporary arrangement. It was a hassle to complete, and improvements were desperately needed.

(Object of the Invention) This invention has been made in view of the above, and its purpose is to provide a layout design that enables efficient layout design support by setting a temporary layout based on layout conditions. The goal is to provide support equipment.

(lI!! Essentials of the Invention) In order to achieve the above object, each of the plurality of components is temporarily arranged within the set area based on various arrangement conditions regarding the relative positional relationship with other components. In an apparatus for designing a layout in a set area, the present invention provides an inference rule storage means 3 in which IW logic rules are recorded for inferring until a layout is designed within a set area based on the various layout conditions.
, a component input means 1 for inputting components for constructing a temporary layout design and setting conditions for the components, and an inference rule storage means 3 for each component inputted from the component input means 1. The gist of the present invention is to include a calculation means 5 that performs calculations to construct a temporary layout design from the inference rules and the setting conditions of the constituent elements.

(Example of the invention) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing the configuration of an embodiment of the present invention.

In the same figure, a CRT 19 which is a terminal unit has a screen area, for example, a three-dimensional coordinate graphic screen consisting of dots (pixels), on which the layout design and various messages related to the vehicle are displayed. Consisting of the component coordinate point name from the user,
Coordinate values, distances indicating arrangement conditions between coordinate points, angles, etc. are input.

The data storage section 7 stores coordinate point names, coordinate values, distances, angles, etc. indicating arrangement conditions between the coordinate points of the constituent elements input by the user, as shown in FIG. 3.

Here, the depression position in FIG. 3 is a three-dimensional coordinate input value from the user, and the C/P stroke indicates distance data, and the input value from the user and the calculation unit 15 described later are
The calculated value (C/P lever length) and the value indicating the allowable value that can be calculated with respect to the user's input value are stored. C/
The initial position P indicates the reference coordinate value of the temporary device of each component.

The inference rule storage unit 9 stores coordinate points of each component.

It stores rules that define placement conditions between objects in terms of distances and angles, and rules for determining temporary devices using these rules. That is, ruIe-C in Fig. 4-a is a distance definition rule, which is a C/P fulcrum set in advance as a reference value and a distance calculated from the C/P fulcrum.
The lever length, the C/P depression position input by the user, and the input value C/P stroke length of distance data from the user from the C/P depression position are stored for each component.

In addition, the rule shown in Figure 4-b is a coordinate determination rule that determines the coordinate value of each component using the distance definition rule described above, and the C/P lever length is determined around the C/P fulcrum of the distance definition rule. The intersection of the curve drawn by the distance and the curve drawn by the distance of the C/P stroke centering on the C/P depression position determines the C/P initial position as the coordinates of the component.

The movement rule storage unit 11 stores movement rules as shown in FIG. 7 described above, and is used to move each component in a direction suitable for the placement condition after the provisional device of each component is completed.

The search unit 13 stores coordinate point names, distance data, etc. of each component input by the user from the input device 17 in the data storage unit 7, and applies the information from the inference rule storage unit 9 to determine a temporary device. Find distance definition rules and coordinate determination rules.

Further, the search unit 13 searches for whether or not the distance data etc. inputted by the user can be calculated, and if the calculation is possible, the calculation unit 15
It outputs a command signal to the device, applies the rule to search whether the placement conditions are satisfied, and displays the status of the temporary device on the CRT 19.

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

Next, the operation of this embodiment will be explained using the processing flowchart shown in FIG.

First of all, for example, a CRT is composed of both sides of graphics.
For example, various menus related to vehicle position design are displayed at 19, and the user selects, for example, the layout design near the driver's seat from the menu, presses the corresponding key on the input device 17 (keyboard), and selects the components necessary for the temporary layout U. After inputting the names of the coordinate points such as the driver's eye point, roof, steering wheel, accelerator, etc., the seat M of the eye point, etc. of the component is entered:
! hm 1 Input the distance, angle, etc. indicating the arrangement conditions between the coordinate points (step 100).

When the input from the user is completed, the search unit 13 stores the input data such as the distance in the data storage unit 7, searches to see if the data can be calculated, and if it can be calculated, searches for the component Display the coordinate points on the CRT 19 and proceed to step 130. If calculation is not possible, proceed to step 1.
Return to 00 and re-enter (steps 110-120)
. When the process proceeds to step 130, the user presses the corresponding key to proceed to step 140 if the coordinate point displayed on the CRT 19 is to be adopted in the layout design; otherwise, the process returns to step 100 (step 130).

Proceeding to step 140, the search unit 13 displays on the CRT 19 one or more coordinate determination rules applicable to determining the coordinate values of the coordinate points from the inference rule storage unit 9. If there is a rule to be applied among the displayed coordinate determination rules, the user presses the appropriate key and proceeds to step 160; if there is no rule to be applied, the user presses the appropriate key and proceeds to step 260 (steps 140 to 150).

When the process advances to step 260, the CRT 19 displays a message asking whether to decide on another coordinate point first, and if the user decides on another coordinate point first, press the appropriate key and step 12
Returns to 0, and returns to step 100 if the decision is not made first.

On the other hand, when proceeding to step 160, the search unit 13
5, the calculation unit 15 calculates the C/P initial position of the coordinate point using the selected coordinate determination rule, and when the calculation is completed, the process proceeds to step 180, and the calculation result is used to calculate the imaginary number solution. etc. are calculated, the process advances to step 270 and C
If the calculation is to be performed using the Haku's coordinate determination rule displayed on RT19, the process proceeds to step 140, and if the rule is not used, the process proceeds to step 260, where coordinate points are selected (steps 160, 170, and 270).

When proceeding to step 180, the search unit 13 performs step 1 if the arrangement of the coordinate points for which the arrangement design is to be performed has not been completed.
Return to step 10 to search for coordinate points that can be calculated, and when the arrangement is complete, proceed to step 190 (step 1
80).

Proceeding to step 190, the calculation unit 15 calculates the distance and angle representing the arrangement conditions between the arranged coordinate points, and the temporary arrangement is completed and the temporary arrangement near the driver's seat f is
19 (step 190).

When the temporary layout near the driver's seat is displayed on the CRT 19, the user proceeds to step 210 if all the components of the temporary layout satisfy the placement conditions, and the layout design is completed. For example, if the coordinates of the eyepoint differ from the arrangement conditions, the corresponding key for moving the coordinates of the eyepoint is pressed and the process proceeds to step 230 (steps 200 to 210).
).

Proceeding to step 220, the search unit 13 searches the movement rule storage unit 11 for a movement rule for moving the coordinates of the eyepoint that differs from the above-mentioned arrangement conditions, and if there is no corresponding movement rule, the process proceeds to step 240, in which the corresponding movement If there is a rule, proceed to step 230.

When proceeding to step 230, the calculation unit 15
Steps 220 to 230) move each component while performing calculations for movement processing and proceed to step 200.

On the other hand, when proceeding to step 240, the search unit 13 proceeds to step 220 and detects the corresponding movement rule if the search unit 13 can search whether the arrangement condition with the above-mentioned object other than the roof, for example, the handle is satisfied, and if it cannot search, the search unit 13 determines whether the arrangement design is satisfied. This becomes impossible and ends (steps 240-250).

As a result, temporary layout is performed based on inference rules suitable for the constituent elements input by the user, so it is possible to reduce the troublesome process from temporary layout to completion of layout design.

(Effects of the Invention) As explained above, according to the present invention, an inference rule is provided for inferring until the layout is designed within a set area based on various layout conditions in advance, and based on the components etc. input by the user. Since the provisional arrangement is performed based on the arrangement conditions, provisional arrangement S1 support can be efficiently performed by setting the provisional arrangement based on the arrangement conditions.
