FIG. 1 shows a functional concept of a diversion design system that is one embodiment of the present invention. The main-purpose design system can be introduced in a form added to, for example, a CAD system of a design / development department of an electrical equipment storage board manufacturer.

  As shown in FIG. 1, according to the diverted design support system, for example, it is easy to design a standard deformation board by changing the specifications of a part of the standard equipment from the design data of the standard board of the electric equipment storage board. can do. Further, it is possible to easily design a custom-made board and other unit boards based on the design data of the standard board. In addition, it is possible to easily design a new special order board or unit board from design data of the special order board or other unit boards.

  Here, in this specification, “design data” means so-called design drawings in general such as cabinet external view, panel drawing, three-dimensional CAD data, plan drawing, cabinet processing drawing, board processing drawing, parts list, etc. These are managed in the design database as electronic data of the CAD system. Each drawing is assigned a figure number. The figure number assigned to design data for one product is particularly referred to as a “master figure number” in this specification. In other words, if you know the master figure number, you can search all design data such as cabinet exterior view, board view, 3D CAD data, and processed drawing of that product, and you can use them to create new drawings. .

  In the present specification, the “unit” means a structural unit that performs a certain function in the electrical equipment storage board. The functions are not limited to electrical functions such as switches (main circuit breaker, branch breaker, etc.), wiring, and switches. For example, mounting brackets for securing electrical equipment and wiring space, and such a space itself can be handled as a unit. Further, a unit that combines a plurality of devices and performs one function, such as a distribution board combining a main trunk and a branch, can be handled as a unit.

  FIG. 2 shows an example of a distribution board composed of one unit. FIG. 3 shows an example of a distribution board unit constituting the distribution board of FIG. In this example, the distribution board unit includes a main bracket 13 in which a main breaker 13a is mounted on mounting rails 11 and 12 arranged in parallel with a width defined by a standard, a branch breaker 14a having a number of distribution circuits, The branch bracket 14 which mounts 14a, ... is attached. For example, as shown in FIG. 3, three-phase bus bars 15 </ b> R, 15 </ b> S, and 15 </ b> T are attached in advance to the distribution board unit between the main bracket 13 and the branch bracket 14. As described above, the electrical equipment storage panel configured by attaching the units to the predetermined mounting rails 11 and 12 is particularly referred to as a “unit panel” in the present specification.

  Among such unit boards, those which are highly versatile and are frequently used as products are particularly referred to as “standard boards” in this specification. Specifically, for example, a product registered as a product model number in a manufacturer's catalog or the like corresponds to the standard board. The standard panel (unit panel) is not limited to a single unit such as the distribution panel of FIG. 2, and may be composed of a plurality of units as shown in FIG. 4, for example.

  For example, the standard panel shown in FIG. 4 includes a wiring space unit (AAA) from the top, a unit (BBB) capable of mounting a main breaker and a branch breaker, a unit (CCC) capable of mounting a contract type device, and a terminal block mounting unit.

As described above, a part in which the specifications of some of the electric devices are changed as long as the form of the unit constituting the standard board is not changed is referred to as a “standard deformation board” in this specification. Examples of changes from the standard board to the standard deformation board include changing the specifications of some electrical devices such as breakers that make up a unit, and increasing or decreasing the number of electrical devices. Here, for example, in the case of a main circuit breaker, the specification change of the electric equipment corresponds to a change in rated capacity amperage, a model change from a circuit breaker to a leakage breaker, and the like.

  In addition, according to the diverted design support system, it is possible to easily design a “special order board” in which a plurality of units are combined according to the specifications required by the customer and these units are arranged at appropriate positions on the board. . Here, FIG. 5 shows an example of a board surface configuration of a custom-made board (unit board).

  5 is an example of a unit board in which a plurality of units are arranged in two rows on the left and right. For example, in the left column A, from above, the unit U1 of the wiring space, the unit U2 having the main breaker and the branch breaker, the agreement type equipment unit U3, the unit U4 of the wiring space, the terminal block mounting unit U5, and the wiring space Unit U6 is mounted.

Of units used in the board. Is stored. FIG. 7C is a diagram illustrating a data structure of a unit information list (for example, UNIT1). In the unit list, at least the unit name of the unit arranged at the arrangement position is associated with the arrangement information of the unit on the board.

  As described above, the design database 3 has a hierarchical structure in which at least unit specifying information, unit arrangement information, and device information are associated with each other in the form of arrangement data for each design data of the existing electrical device storage board. A data structure is stored. As described above, the main circuit information list and the unit information list can be shared by hierarchizing the design data in the design database 3. This makes it easy to design a new product by diverting the common information list, reduce the data capacity of the design database 3, and increase the speed and efficiency of searching the flow source data.

  In the diversion design support system 1 according to the present embodiment, each control processing means for supporting the diversion design of the electrical equipment storage board described below is realized by the host computer 2 executing arithmetic processing according to a predetermined program. The Hereinafter, according to the flowchart of FIG. 8, the specific example of the utilization design assistance method of an electrical equipment storage panel is demonstrated.

(Diversion source data selection means)
First, a designer who intends to divert a new electrical equipment storage panel (hereinafter referred to as “user” of the present system) logs into the host computer 2 from any terminal 4 and activates the system. At this time, the host computer 2 displays, for example, a drawing basic data screen 101 as shown in FIG. 9 on the display of the accessed terminal 4. The user inputs the master figure number indicating the design data of the diversion design source into the input / display item field (hereinafter simply referred to as “box”) 101a (step S11).

  Even if the user does not know the flow source diagram number, the user inputs, for example, the name and model number of the electrical equipment storage panel registered in the catalog into the box 101b, and the design data of the flow source is input to the working area or the terminal 4 Can be loaded. Further, based on the user account information at the time of login, the host computer 2 automatically loads the data currently being designed by the user or the last updated design data into the working area or is already stored in the working area. The design data may be displayed on the drawing basic data screen 101 as it is.

(Diversion source data load means)
The host computer 2 retrieves the flow source design data corresponding to the input figure number from the drawing basic data list (see FIG. 7A) of the design database 3 and loads it into the working area of the storage device. The diversion source data loaded in the working area relates to at least unit specifying information for specifying a unit constituting the electric equipment storage board of the diversion source, unit arrangement information relating to the arrangement of each unit, and internal equipment constituting the unit. Device information is included.
The working area may be formed in a storage device of the host computer 2, may be formed in a predetermined storage device on the network, or may be formed in a storage device of the terminal 4 accessed by the user. The host computer 2 displays predetermined items (for example, the product name and model number of the board) of the basic drawing data loaded in the working area in predetermined boxes 101b, 101c,. Step S12).

(Diversion source data change means)
<Cabinet change>
Thus, when the diversion source electrical equipment storage board is specified, the box 10b, 101c, etc. of the drawing basic data screen 101 shows the name of the diversion source board, the name of the cabinet used for the board, The model number is displayed. The user confirms the product name or model number, and if the cabinet is to be changed, the user can enter and specify the product name or model number of the new cabinet in the box 101c (step S13). Then, the diversion source data changing unit immediately changes the cabinet information of the working area by background processing according to the input designation by the user.

<Change unit>
In addition, the user can easily change the specifications of the units used in the original electrical equipment storage board, and add, remove, and change the mounting position. That is, when the unit name button 101g on the drawing basic data screen 101 is clicked, a unit showing a list of units used in the diversion source electrical device storage panel as shown in FIG. A name screen 102 is displayed (unit identification information).
This processing is performed by causing the host computer 2 to display the information on the terminal 4 based on the unit information list (see FIG. 7C) referenced from the basic drawing data loaded in the working area.

  The unit name screen 102 displays a list of units and a mounting position of the unit (panel row and stage) (unit arrangement information). Therefore, the user can confirm them while looking at the unit name screen 102, and can add, remove, and change the mounting position on the unit name screen 102 if necessary (step S14). For example, when adding a new unit, it is only necessary to input a new unit name in the blank of the position to be mounted on the unit name screen 102. Further, when removing a unit, the unit name in the item column to be removed on the unit name screen 102 may be deleted. Further, when changing the mounting position of the unit, it is only necessary to move the unit name between the corresponding fields on the unit name screen 102 (for example, copy and paste or drag).

  When the unit mounting position is changed on the unit name screen 102, the corresponding unit information in the working area is immediately updated.

<Change device>
In addition, the user can easily change the specifications of internal devices (simply referred to as “devices” or “electric devices”) used in the diversion source electrical equipment storage panel, and add, remove, or change the arrangement. Can do. When the user clicks the main circuit button 101j on the drawing basic data screen 101 or the main circuit button 102j on the unit name screen 102, a main circuit screen 103 as shown in FIG. (Device information) This processing is performed by causing the host computer 2 to display the information on the terminal 4 based on the main circuit information list (see FIG. 7B) referenced from the drawing basic data loaded in the working area.

  In the main circuit screen 103, internal devices (including electric devices, wiring devices, etc.) used in the diversion source electric device storage panel, or devices automatically updated by the unit specification change designation in step S14 are displayed. A list containing is displayed for each function category (main, feed, branch, etc.). The main circuit screen 103 also displays arrangement information of each device on the board surface.

  The user confirms the device while looking at the main circuit screen 103, and if necessary, can change the number of devices, change the specifications, change the arrangement, etc. on the main circuit screen 103 (step S16). For example, when changing the number of devices, it is only necessary to input the changed number in the corresponding item field of the main circuit screen 103. When changing the specification of the device, the changed device symbol or model number is supported. Enter in the item field. Similarly, addition and removal of devices can be easily performed by changing the description in the corresponding item column.

  When the information on the internal device is changed on the main circuit screen 103, the corresponding device information in the working area is immediately updated.

(Internal device arrangement calculation means)
<Mountability determination means>
When the internal device is changed based on information input to the terminal 4 by the user, the host computer 2 retrieves the specification data of the designated device from the design database 3 and the electronic data book and loads it into the working area. . The specification data of the device includes specifications such as the external dimensions of the device and the mounting type (with screw holes, plug-in). The internal device arrangement calculation means refers to these specification data, and calculates the arrangement to the diverted cabinet or the unit in the change designated cabinet, specifically, the mounting position, the occupied space, the wiring space, and the like. Then, the mountability determination unit determines whether or not the change-designated internal device (the number of installed devices may increase) can be mounted on the corresponding unit (step S17).

  The mountability determination means displays an error such as “unmountable” on the display of the terminal 4 when the compatibility between the specified internal device and the unit cannot be obtained or when it is determined that the internal device is not stored in the cabinet. Then, the user may be prompted to change the design.

(External device arrangement calculation means)
When the compatibility between the internal device and the unit and the storage in the cabinet are recognized, the external device arrangement calculation means determines the default arrangement of the external device that appears on the external surface of the cabinet based on the calculated arrangement information of the internal device. Calculation is performed (step S18).
Such external device arrangement calculation processing is performed in real time in response to a designation input of information related to a device by the user in the working area described above.

  Here, the operation of the external device arrangement calculation means will be further described taking the circuit screen displayed by clicking the “C” button on the main circuit screen in FIG. 12 and the door device screen in FIG. 13 as examples. The main circuit screen is displayed on the terminal 4 by clicking the main circuit button 101j on the drawing basic data screen 101, and the door device screen is displayed on the terminal 4 by clicking the door device button 101i on the drawing basic data screen 101. Is displayed.

In the diversion design system, the layout development processing of the external device is automatically calculated by the background processing of the host computer 2. For example, the arrangement of external devices related to “feed” on the main circuit screen shown in FIG. 12 is expanded in the item column of (1) trunk section of the door device screen 110 shown in FIG. Further, the arrangement of external (door) devices such as switches related to the common part of the circuit screen is expanded in the item column of (3) common part of the door device screen 110 shown in FIG. Similarly, the arrangement of external devices such as lamps related to the individual parts of the circuit screen is expanded in the item column of (2) branch / alarm unit of the door device screen 110 shown in FIG.
Note that <door 1> and <door 2> on the door device screen correspond to the left door and the right door, respectively, which are two in the cabinet.

  The display means displays an image of the external device appearing on the external surface of the cabinet as illustrated in FIG. 14 on the display of the terminal 4 (step S19). FIG. 14 is a cabinet external view 210 created based on default development information shown on the door device screen of FIG.

(External device layout change means)
When the user desires to change or change the external device (door device) displayed by default (step S20: YES), the user can easily specify the external device on the door device screen 110 and change its arrangement. (Steps S21 and S22).

<Door device change example 1>
As a first example, when a design change is made to move, for example, a part or all of the external devices arranged on the left door to the right door based on the default initial information, <door 1> on the door device screen 110 The information in the device item column to be moved can be specified by copying and pasting or dragging to the device item column to which <door 2> is moved (step S21).
For example, FIG. 15 shows the door device screen 111 after the change. On the door device screen 111, the circuit number corresponding to the third stage of the (2) branch / alarm unit of <door 1> 3 is moved to the first stage of the (2) branch / alarm unit of <door 2>. By this operation, the circuit No. 3 meter, lamp and switch can be moved to the right door. For example, a cabinet external view 211 shown in FIG. 16 is displayed on the display of the terminal 4 (step S22).

<Door device change example 2>
Further, as a second example, FIG. 17 illustrates a door device screen 112 in which the design of the arrangement order of the external devices arranged on the left door is changed. On this door device screen 112, the circuit number corresponding to the first row in the item column of (2) branch / alarm section of <door 1> is displayed. 1 is moved to the third stage, and the circuit No. 1 in the third stage. 3 is moved to the first stage. By this operation, the circuit No. 1 and no. 3 can be exchanged. For example, a cabinet external view 212 in which meters and lamps are exchanged as shown in FIG. 18 is displayed on the display of the terminal 4.

<Door device change example 3>
As a third example, FIG. 19 illustrates a door device screen 113 from which one circuit of external device arranged on the left door is removed. On this door device screen 113, the circuit No. in the item column of (2) branch / alarm section of <door 1> is displayed. 2 has been deleted. By this operation, the circuit No. For example, as shown in FIG. 20, a cabinet external view 213 from which one circuit meter and lamps are removed is displayed on the display of the terminal 4.

  In this way, the user can quickly find an error in the device that appears on the outer surface of the cabinet before drawing, and can easily correct the error on the screen. Therefore, it is not necessary to repeat the design flow again.

(Drawing data creation means)
Through the above steps, new design data is created on the working area based on the design data of the flow source. Based on the created design data, the drawing data creation means executes a drawing process for creating electronic data drawings such as a cabinet external view, a board drawing, a cabinet drawing, a board drawing of a new electrical equipment storage board, The data is output to the output device 5 such as a printer (step S23). For example, the cabinet processing drawing is created based on the arrangement of the external device determined by the external device arrangement calculation unit and the external device arrangement change unit described above.

(Processing data creation means)
The machining data creation means creates machining data such as NC data for machining a cabinet or board of a new electrical equipment storage board based on the design data such as the cabinet drawing and board machining chart created. be able to.

(Design data update means)
