An embodiment of the present invention is shown below.
FIG. 1 is a block diagram showing the configuration of the board design support system of the present invention, where 10 is a symbol diagram database, 11 is a product schematic database, 12 is a selection means, 13 is a display means, and 14 is a product schematic creation means. Further, 15 is an input means and 16 is an output means. Further, 18 is a symbol diagram changing means, and 19 is a connection determining means. The functions and the like of each means will be described in sequence. Needless to say, these may be provided integrally or may be arranged in a distributed manner via a communication line.

A large number of symbol diagrams are stored in the symbol diagram database 10. The symbol diagram is a wiring diagram of a circuit unit composed of electrical and electronic devices. The circuit unit is a combination of electrical and electronic equipment installed in the panel such as the main circuit breaker, branch breaker, terminal block, and measuring instrument, and is unitized according to the arrangement of the branch breaker and the difference in the input / output direction. There is. Symbol diagrams are roughly divided into categories such as lamp panel type, power panel type, and option type.

The symbol diagram of the lamp board type is shown in FIGS. 2 to 5. FIG. 2 is a symbol diagram in which the name of the circuit unit is "basic". In FIG. 2, 20 is a main circuit breaker, 21 is a bus bar connected to the secondary side of the main breaker 20, 22 is a branch breaker connected to both sides of the bus bar 21, 23 is a secondary feed terminal, and 24 is an option. It is a space for installing equipment. In this way, the symbol diagram is a diagram that symbolizes and shows the connection state of the electrical and electronic devices arranged in the panel.

FIG. 3 shows a symbol diagram in which the name of the circuit unit is "branch one-sided arrangement". In this symbol diagram, the branch breaker 22 is connected to only one side of the bus bar 21. FIG. 4 shows a symbol diagram in which the name of the circuit unit is "lower incoming wire / with terminal block". In this symbol diagram, the main circuit breaker 20 is arranged below the bus bar 21, and the terminal block 25 is arranged on the primary side of the main circuit breaker 20. FIG. 5 shows a symbol diagram in which the name of the circuit unit is “with instrument”. In this symbol diagram, the ammeter 26 is connected to the upper part of the bus bar 21.

Figure 6 and below show the symbol diagram of the option type. The option type symbolizes the connection state of the equipment installed as an option in the panel. Fig. 6 is a symbol diagram of the circuit unit named "emergency circuit", and the emergency circuit breaker on the primary side of the main breaker 20. 27 is connected. FIG. 7 is a symbol diagram of the circuit unit whose name is “secondary feed circuit”, and the circuit breaker 28 for secondary feed is connected to the space 24 in FIG. 2 described above. There are many other symbol diagrams, but the description will be omitted. Each symbol diagram shows the connection state and layout of electrical and electronic equipment.

The wiring diagram of the circuit unit differs depending on the unit conditions, which are the conditions of the electrical and electronic devices constituting the unit, specifically, the capacity and type of the breaker, the number of branch breakers, the capacity of the optional equipment, and the like. It is possible to use all of these as symbol diagrams, but considering operability, it is preferable to simplify the display on the input screen by using a common symbol diagram for wiring diagrams with different unit conditions. .. Therefore, in this embodiment, a unit condition is added to the selected symbol diagram so that a specific wiring diagram can be specified.

Here, the unit conditions include, but are limited to, the capacity and function of the main breaker (leakage function, etc.), the type of branch breaker (plug-in type, screw type, 2P size, 3P size, etc.), and the number of branches. It may be a condition for specifying an electric / electronic device constituting a circuit unit, a condition for arranging the electric / electronic device, or the like.

The selection means 12 is a means for the designer to select a desired symbol diagram from the symbol diagram database 10, and a symbol that matches the conditions by inputting a type and an input / output line position as shown in the right column of FIG. You can display the diagrams and drag and drop the symbol diagram selected from them to the connection diagram summary column on the display screen. As shown in FIG. 9, the display means 13 creates a product schematic diagram from the selected symbol diagram and displays it on the screen. Here, the product schematic is a wiring diagram, a layout diagram, or the like for grasping the outline of the distribution board or the distribution board, and may be simplified to the extent that the product diagram completed by the drawing can be imagined. ..

However, as described above, since the symbol diagram is a diagram showing the connection state of the electrical and electronic equipment as a symbol, the specific arrangement and the details of the equipment specifications can be changed, and these can be changed by inputting the unit conditions. Be changed. For example, if the main capacity is 100 A, the number of branches is 14, and the unit conditions are input in FIG. 8, the unit conditions are combined with the drag-and-drop “basic” symbol diagram, and the wiring diagram and the layout diagram shown in FIG. 9 are combined. And the equipment details are displayed. Such a change of the symbol diagram is performed by the symbol diagram changing means 18. The layout drawing is a drawing of the actual layout of electrical and electronic devices in the panel, and the layout is clearer than the symbol diagram, but the wiring status does not appear. Further, in the device specification column, information on the type and quantity of electrical and electronic devices stored in the panel grasped from the product schematic, or the size of the box (cabinet) in which the electrical and electronic devices are stored is displayed. Further, it is preferable that the estimated amount is calculated from the display contents of the equipment detail column, and when the symbol diagram is selected, the estimated amount is output at the same time as the product schematic diagram.

Further, as shown in FIG. 9, another symbol diagram can be dragged and dropped from the option type symbol diagram to the connection diagram summary column to be combined with the previously selected symbol diagram. In FIG. 9, the symbol diagram of the “secondary feed circuit” is selected and dragged and dropped. When the input is completed, the product schematic drawing means 14 creates a product schematic drawing by combining the selected symbol diagrams, the output means 16 outputs the product schematic drawing, and the product schematic drawing is stored in the product schematic drawing database 11.

When a plurality of symbol diagrams are selected in this way, the connection determination means 19 determines whether or not the connection is appropriate because there are cases where a connection in which the symbol diagrams are combined is possible or impossible. Since "basic" and "secondary feed circuit" are selected in FIG. 9, the secondary feed circuit can be connected to the basic secondary feed terminal 23 as shown in FIG. 10, and the secondary feed circuit can be connected to the basic space 24. The product schematic has been modified and displayed to place a breaker for the secondary feed circuit. Further, in the device detail column, the capacity and the number corresponding to it are displayed.

The suitability of wiring is determined by criteria such as whether the distribution methods of both are the same, whether they are in the same system, and whether they can be electrically connected. For example, a single-phase three-wire circuit and a three-phase three-wire circuit cannot be connected because the power distribution method is different. In this case, it is desirable to warn the designer by displaying a warning or changing the display color.

FIG. 23 shows the flow of the present invention. Whether or not the selected symbol diagrams can be connected is determined, and if the connection is possible, the product schematic drawing means 14 creates the product schematic diagram, and if the connection is not possible, a warning is displayed. Further, as in the second embodiment described later, even if the connection is not possible, it may be possible to coexist in the same panel, and the connection determination means 19 also determines this point. In the present invention, it is not always necessary to select a plurality of symbol diagrams, and a single symbol diagram may be used.

As described above, according to the board design support system of the present invention, it is possible to proceed with the board design while checking the connection state and layout of the electrical and electronic equipment on the screen, so that the design does not differ from the assumption. .. By pressing the input completion button, the wiring diagram and layout diagram can be output on paper, and the quotation can be automatically created and output from the device information. The product drawing at the time of input completion is stored in the product drawing database 11.

(Example 1)
The first embodiment is as described above, and is an example in which the symbol diagram of the “basic” and the symbol diagram of the “secondary feed circuit” are selected and combined. In this case, since the two symbol diagrams can be connected, the result shown in FIG. 10 can be obtained.

(Example 2)
The lamp panel type symbol diagram and the power panel type symbol diagram cannot be connected because the power distribution method is different, but they can coexist in the same panel. In this case, it is necessary to select the position of the power panel type symbol diagram on the top, bottom, left, and right of the lamp panel type symbol diagram. An example is shown below.

First, as shown in FIG. 11, the lamp panel type and the upper incoming line were selected from the categories such as the symbol diagram type selection and the incoming / outgoing line position. The display contents of the symbol diagram were changed accordingly, and here, the symbol diagram of "branch one-sided arrangement" was selected. Also, input the unit conditions such as the main capacity.

Next, as shown in FIG. 12, the power panel type was selected from the type selection category, and the "basic" symbol diagram was dragged and dropped from the displayed symbol diagram to the right area of the connection diagram summary column. Although these symbol diagrams cannot be connected, they can coexist in the same board. Therefore, as shown in FIG. 13, the connection diagram summary column is divided into left and right, and includes multiple symbol diagrams. A product schematic is displayed. At this time, the partition plate that partitions the left and right circuit units is automatically added. However, as shown in FIG. 14, if the "basic" symbol diagram of the power panel type is dragged and dropped to the lower area of the connection diagram summary column, the power is generated below the symbol diagram of the lamp panel type as shown in FIG. A board-type "basic" symbol diagram is placed, and a product schematic is displayed accordingly. In this way, the designer can proceed with the design while checking the overall layout.

(Example 3)
The third embodiment is an example in which the unit condition is input after selecting the symbol diagram.
First, as shown in FIG. 16, the “basic” symbol diagram is dragged and dropped into the connection diagram summary column, and then the unit condition is input or selected as shown in FIG. As a result, as shown in FIG. 18, a symbol diagram and a product schematic modified to match the unit conditions are displayed. However, in the case of subsequent correction, a screen for inputting correction information of the unit condition is displayed by selecting the product schematic to be corrected as shown in FIG. By inputting the correction information of the unit condition here, the wiring diagram, the layout diagram, and the equipment details can be corrected as shown in FIG. The same applies when deleting a product schematic, and the product schematic to be deleted may be selected and a deletion instruction may be issued. After the work is completed, the drawing result can be output by pressing the input completion button.

(Example 4)
In the above embodiment, the symbol diagrams are dragged and dropped one by one, but as shown in FIG. 21, a plurality of symbol diagrams are selected, each unit condition is input, and the selection is confirmed with the selection completion button or the like. A product schematic may be displayed.

As described above, according to the board design support system of the present invention, it is possible to proceed with the design while looking at the layout, and even if the designer has little knowledge or experience, the product drawing and quotation as expected can be obtained. There is an advantage that can be created.
