Description

  The present invention relates to a panel rearrangement design apparatus used for rearranging and designing a panel such as a distribution board or a distribution board from a standard specification.

  Boards such as switchboards and distribution boards have built-in components such as main breakers and branch breakers inside the cabinet. Panel manufacturers prepare a number of standard products according to the purpose of the panel and the current carrying capacity. If the customer's requirements do not match the standard products, it is necessary to rearrange some of the components based on the standard products. There is.

  However, the recombination requested by the customer may be unacceptable in size or electrically. For example, this may be the case when trying to replace the component with a size that cannot be stored in the cabinet, or adding a branch breaker beyond the capacity of the main breaker. It is not always easy to accurately determine the suitability of such rearrangement in a state where there is no real thing, and it is particularly difficult for salespeople and agents to immediately determine the appropriateness of customer requests. Therefore, as disclosed in Patent Document 1, a device has been proposed in which a database of component parts of a panel is provided on a server, and the panel is automatically designed and operated automatically through a terminal.

  In the apparatus disclosed in Patent Document 1, when a recombination content is input, automatic design proceeds without a human being determining whether or not it is appropriate until the final stage. Therefore, the number of combinations becomes enormous. Therefore, conventionally, recombination possible conditions or impossible conditions are registered as a drawing condition database for every product (for each model number), and it is determined whether or not input recombination is possible.

However, in such a conventional technique, it is necessary to reflect the restrictions on each product in all the drawing condition databases, and there is a problem that the drawing condition database becomes large. In addition, when a rule change related to restrictions occurs, it is necessary to individually modify the drawing condition database for all products, which requires a lot of maintenance work. In addition, in order to determine whether recombination is appropriate or not, it is necessary to search the entire drawing condition database.
JP 2000-305972 A

  Therefore, an object of the present invention is to avoid the need to search the entire database when judging whether or not recombination is appropriate, to avoid an enormous database and an increase in maintenance cost, and to accurately determine whether or not recombination is appropriate. It is to provide a panel rearrangement design apparatus that can perform the above.

The panel rearrangement design apparatus of the present invention made to solve the above problems is
A device for redesigning some components from a standard product with multiple types of components arranged inside the cabinet,
A standard product database in which records of model numbers and component parts of standard products roughly classified into product groups are stored in a storage area;
Model number input means for inputting the model number of the standard product to be recombined,
Product search means for reading out the data of the model number input from the model number input means from the standard product database onto the calculation means,
Display means for displaying on the screen the component of the read model number;
Recombination input means for inputting recombination contents;
A judging means for judging the suitability of the inputted recombination content;
With automatic operation drawing means for drawing the recombination result,
The determination unit includes a component part determination unit that compares the recombination restriction condition for each component recorded in the standard product database with the input recombination content;
A program judging means for judging the suitability of input recombination contents for each product group on a computing means in accordance with a common rule program that defines restrictions common to each product group for each product group. It is.

  Note that, as in claim 2, it is possible to adopt a configuration in which the model number input means, the display means, and the recombination input means are arranged on the terminal side, and other means are arranged on the server side. Further, as in claim 3, a plurality of types of components can take a configuration including a main breaker and a branch breaker. Further, as in claim 4, the reconfiguration constraint condition for each component can take a configuration including the capacity of the main breaker, the capacity of the branch breaker, and the number of branches.

  In the panel rearrangement design apparatus of the present invention, a part of the standard product components stored in the standard product database is rearranged according to the input rearrangement contents, and is displayed on the screen in the same manner as in the prior art. However, it differs from the prior art in that the component part determining means and the program determining means are used in combination as the determining means for determining the suitability of the inputted recombination contents. Among these components, the component determination unit is a unit that reads the reconfiguration constraint condition for each component recorded in the standard product database on the calculation unit, and compares it with the input reconfiguration contents. On the other hand, recombination constraint conditions must be set.

  However, the program judgment means judges the suitability of the input recombination content for each product group according to a program that defines the constraint conditions common to each product group for each product group, and the constraint conditions are set for each product group. Has been. For this reason, according to the present invention, it is not necessary to reflect the restrictions on each product in all the databases as in the prior art, and the database can be prevented from becoming large. In addition, when there is a change in the rules regarding restrictions, it is not necessary to individually modify the drawing condition database for all products, and only the program needs to be modified, reducing the maintenance effort.

  Panels subject to the present invention are switchboards, distribution boards, control panels, etc., but since distribution boards are divided into general distribution boards and residential distribution boards, there are hundreds of kinds of products as a whole. It is roughly divided into groups. These are structures in which multiple types of components are arranged inside the cabinet, but typical components are the main breaker and branch breaker, with other optional parts added as necessary. is there. In this specification, only the main breaker and the branch breaker are taken up as constituent parts to simplify the explanation, but the same applies when other optional parts are included.

  FIG. 1 is an apparatus configuration diagram showing an embodiment of the present invention, in which 1 is a server, and 2 is a terminal connected to the server 1 directly or via a communication line. The terminal 2 may be singular or plural, and preferably includes a printer or plotter for outputting the drawn drawing on paper. The server 1 includes a CPU and a RAM constituting the calculation means, and a storage area configured on a hard disk and a ROM.

  A standard product database 3 and a common rule program 9 are stored in the storage area of the server 1. As will be described below, the standard product database 3 is a collection of standard product model numbers and their component part records, which are roughly classified into product groups.

  FIG. 2 is a diagram showing a model number of a certain standard product in the standard product database 3 and a record of its component parts. This standard product is a standard distribution board, has a model number “AA150 16E 4N”, and indicates that the following internal units are housed in a cabinet. The phase wire type “1Φ3W” in the inner unit column means a single-phase three-wire type. The main trunk and the branch indicate the model numbers of the main component breaker and the branch breaker, and 16 branch breakers are connected as standard products, but there are four spare spaces. The next cabinet column displays the size and name (model number). The symbol of the model number of the breaker indicates the model, amperage frame (breaker case size), number of poles, and capacity.

  Finally, a restriction column is provided, and the upper limit values of TM, TS, and TB are shown. TM means the capacity of the main breaker and indicates the limit that it must not exceed 200A. TS means the capacity of the branch breaker and indicates the limit that it must not exceed 30A. TB means the maximum value of the number of branches, and indicates a limit that must not exceed 20.

  As shown in the above example, the standard product database 3 of the present embodiment includes the standard product model number, phase wire system, component model number, branch number, spare circuit number, cabinet model number, limit value (main capacity, It has a structure in which records including branch capacity and maximum number of branches are integrated for each standard product model number. These standard products are roughly divided into product groups. As described above, the product group includes a distribution board, a general distribution board, a residential distribution board, and a control panel. Such a product group can be displayed, for example, by the initial letter of the model number of the standard product. FIG. 2 shows an example of a record, and the record structure is not limited to this.

  The terminal 2 is provided with model number input means 4. This is a means for inputting the model number of a standard product as a base for recombination, and a keyboard, mouse or other appropriate input means can be used. The input model number is transmitted to the server 1, and the product search unit 5 of the server 1 reads the model number data input from the model number input unit 4 from the standard product database 3 onto the calculation unit. Then, the read product data is transmitted to the terminal 2, and the component part of the read model number is displayed on the screen on the display unit 6 of the terminal 2.

  The upper part of FIG. 3 shows an example of the screen display, and is an example in which the model number “AA 150 16E 4N” shown in FIG. 2 is read. The numbers in the right column of FIG. 3 indicate the number. The format of the screen display is not limited to that shown in FIG.

  Further, the terminal 2 is provided with recombination input means 7 for inputting the recombination contents of the component parts based on the displayed standard product. An appropriate input means such as a keyboard, a mouse or the like can be used as the recombination input means 7, and FIG. 3 shows an input example in the case where the branch breaker is reconfigured from one having a capacity of 20A to 30A.

  In this way, the recombination contents input from the recombination input means 7 of the terminal 2 are transmitted to the server 1, and the determination means 8 determines the suitability of the recombination contents. The determination unit 8 includes a component part determination unit 9 and a program determination unit 10.

  First, the component determination unit 9 reads the recombination constraint condition for each component recorded in the standard product database on the calculation unit and compares it with the input recombination content. Note that this determination is easy because the data of the standard product that is the base of the recombination has already been called on the computing means. In this example, the inputted recombination content is that the branch breaker is changed from 20A to 30A, and is compared with the value of TS in the restriction column in the record of the standard product shown in FIG. In this example, 30A is within the limit value, so the recombination constraint condition for each component can be cleared. If the determination by the component determination unit 9 is OK, the determination by the program determination unit 10 is started. However, in the case of NG, the recombination content is inappropriate at that stage, so that information is displayed on the screen of the terminal 2. Display is completed. The flow is shown in FIG.

  The program judging means 10 judges the suitability of the inputted recombination contents for each product group on the computing means in accordance with a common rule program that defines constraint conditions common to the product group for each product group. The common rule program is stored in the storage area of the server 1, and is configured as a program A, a program B, a program C, a program D, and a program E for each product group as shown in FIG. Assuming that the program A is a standard distribution board in the product group, in this example, only the program A needs to be called and executed on the calculation means, and the program B and other programs corresponding to other product groups need to be executed. Absent.

  Since the content of the common rule program defines common rules for the product group, it naturally depends on the product group. The limit values in the standard product database stipulate numerical limits such as the number of components, capacity, etc., whereas in the program determination means 10, the number of breaker poles, model, cabinet type, etc. It is determined whether or not an automatic operation diagram accompanying a structural change is possible. Here, as an example, the contents of the program A for the standard distribution board are shown in FIG.

  First, in step 1, it is determined whether or not there is a model number to be rearranged in the product group targeted by the program A. If not, the program A is not executed and the program B is shifted to the next program B. If there is a model number, in step 2, it is determined whether or not the main breaker AF (ampere frame) has been changed. If there is a change, an NG determination is made at that point and the process ends. That is, the common rule is that the size of the main breaker cannot be changed.

  If step 2 is cleared, it is next determined in step 3 whether or not the number of poles of the main breaker is changed. A typical change in the number of poles is a change between two and three poles. If there is no change, it is determined in step 4 whether or not the branch type is changed. The branch type is, for example, a change between a plug-in type and a screw type. If there is no change, it is determined in step 5 whether or not the cabinet has been changed.

  In steps 2, 3, and 4, no change was allowed, but the cabinet was allowed to change within the set conditions. Specifically, reduction of the width dimension and reduction of the depth dimension are not possible because the internal device may not be able to be accommodated, but enlargement is allowed. However, when the rearrangement is a change from indoor use to outdoor use, the depth dimension must be increased by 50 mm or more. This is because a change to a waterproof structure is required.

  The contents of the program A are as described above. When all the determinations in these steps are OK, it is determined that the rearrangement contents are appropriate, and the result is displayed on the terminal 2 and the server 1 is automatically operated. The means 11 plots the recombination result. However, when NG is determined in any step of the program A, the result is displayed on the terminal 2 and the rearrangement work is finished.

  In the program A, the AF of the main breaker, the change in the number of poles, the change in the branch type, and the change in the cabinet type were sequentially checked. However, in the program B, for example, the type of the main breaker, the main breaker, etc. Changes in the type of devices and whether or not optional devices are added are checked. Only the change from the circuit breaker to the earth leakage breaker is allowed to change the type of main breaker, and the addition of optional equipment is only allowed to add a time switch.

  As described above, the contents of the program AE vary depending on the product group, and can be appropriately programmed for each product group. However, since it is common to all standard products belonging to the product group, it is easier than setting constraints for each product, and it is not necessary to search the entire database when judging the suitability of recombination. Enormous enlargement and increase in maintenance costs can be avoided. Note that functions common to a plurality of product groups may be determined again by different programs. That is, for example, the standard product may be determined by the program A, and the common function may be determined again by the program E.

  As described above, if it is confirmed by the component part determination means 9 and the program determination means 10 that recombination is possible, the result is displayed on the terminal 2 and the automatic operation means 11 of the server 1 displays the recombination result. Is an automatic diagram. The drawing is output as a rearranged product drawing, and can be displayed on the terminal 2 or printed. As a result, the customer can confirm the product form in which the standard product has been rearranged.

It is an apparatus block diagram which shows embodiment of this invention. It is a figure which shows the model number of a certain standard product in a standard product database, and the record of the component. It is the screen display example of the read product data, and the screen display example of recombination input. It is a flow for determining the suitability of the rearrangement content by the determination means. It is a block diagram which shows a common rule program group. FIG. 6 is a detailed flowchart of program A. It is a simplified flowchart of programs A and B.
