  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

  First, the function and configuration of the wiring design system 1 according to the embodiment will be described with reference to FIGS.

  The wiring design system 1 is a computer system that automatically designs indoor wiring of electrical equipment arranged in a building such as a house. As shown in FIG. 1, a wiring design system 1 includes a client terminal (first computer) 10 used by a customer (user) such as a construction company or a construction shop, and a design server installed in a company that designs indoor wiring. (Second computer) 20 and a factory terminal 30 installed in a factory for manufacturing a unit cable (wiring cable) based on the design. The client terminal 10 and the design server 20, and the design server 20 and the factory terminal 30 can communicate with each other via a network N configured by the Internet or the like. The client terminal 10 and the factory terminal 30 cannot communicate. Although FIG. 1 shows only one client terminal 10 and factory terminal 30, the wiring design system 1 may include a plurality of such terminals.

  First, the client terminal 10 will be described. As shown in FIG. 2, the client terminal 10 includes an input receiving unit (receiving unit) 11 and a communication unit (transmitting unit) 12 as functional components.

  As shown in FIG. 3, the client terminal 10 includes a CPU 101 that executes an operating system, application programs, and the like, a main storage unit 102 that includes a ROM and a RAM, an auxiliary storage unit 103 that includes a hard disk, The communication control unit 104 includes a network card, an input unit 105 such as a keyboard and a mouse, and an output unit 106 such as a monitor. Each function of the client terminal 10 reads predetermined software on the CPU 101 or the main storage unit 102, operates the communication control unit 104 under the control of the CPU 101, and stores data in the main storage unit 102 or the auxiliary storage unit 103. This is realized by reading and writing.

  Returning to FIG. 2, the input reception part 11 is a part which receives the data which the user input via the input screen.

  The input receiving unit 11 displays an input screen D as shown in FIG. 4 on the monitor, image data of the floor plan, a symbol (graphic symbol) indicating the installation position of the electrical equipment with respect to the floor plan, address, floor plan, area Such as property information and design auxiliary information necessary for branch circuit classification, etc. are received. Note that the electrical equipment is, for example, an outlet, a switch, a lighting fixture, and the like. The input screen D is a web application implemented on a web browser, and includes a display unit Da that displays a floor plan and symbols, and buttons Db for performing various editing operations. This input screen D can be used only by those who are registered as users.

  When the ID and password registered by the user at the time of starting the application are requested and the ID and password are input, the input screen D can be used. If there is a web browser, there is an advantage that other special software is unnecessary and distribution and system update are easy. Without using a normal web application that is activated on the server by access from the client, the activation software is automatically taken into the client terminal and activated without the user's consciousness, so that a complicated operation such as a CAD operation can be quickly performed. The method is more preferable.

  When the user performs an operation of opening the image file of the floor plan, the floor plan M is displayed on the display unit Da. At this time, the input receiving unit 11 holds the read image file data as image data. The file format of the image data is, for example, TIF (Tagged Image File) format, BMP (bitmap) format, PDF (Portable Document Format) format, DXF (Drawing Interchange File) format, SXF (Scadec data eXchange Format) format. Although there is, it is not limited to these.

  Subsequently, the user places the symbol S on the floor plan M. At this time, the input receiving unit 11 generates and holds equipment data indicating the identifier, type, drawing position (coordinates), and the like of the symbol S. For example, the input reception unit 11 generates facility data including an identifier “001”, a type “outlet port”, and a drawing position “x1, y1”.

  Further, the user inputs design auxiliary information necessary for classifying the branch circuit by drawing it on a floor plan, for example. For example, the user provides a section by dividing a range in which one branch circuit is wired in the floor plan M in the screen D of FIG. When the section is provided, wiring beyond the section is not performed when determining the wiring of the electrical equipment. However, regarding the switch circuit, when a switch for operating a load (such as lighting or a ventilation fan) in a certain section is outside the section, wiring is performed across the section. When a section is input, the input receiving unit 11 generates and holds section data indicating the section identifier, drawing position (coordinates), and the like. Furthermore, when the user inputs property information, the input receiving unit 11 holds the information.

  The user creates the facility layout diagram K as shown in FIG. 4 by performing the above-described input operation. When the user performs an operation for transmitting the facility layout drawing K to the design server 20, the input receiving unit 11 stores the image data, facility data, section data, property information, and the user who identifies the user. The ID and the request ID for identifying the design request are output to the communication unit 12. The facility data, section data, and property information are output in XML (Extensible Markup Language) format, but the data format is not limited to this, and any method may be used.

  The input receiving unit 11 further has a function of acquiring design data and estimate data, which will be described later, from the design server 20, displaying a design drawing and an estimate, and receiving editing of the design drawing. Specifically, the input receiving unit 11 generates a drawing request signal including a user ID and a request ID based on a user input, and outputs the drawing request signal to the communication unit 12. And the design data and estimation data which were sent according to the signal are displayed on the display part Da. The input receiving unit 11 also has a function of acquiring the request data once transmitted to the design server 20 and receiving a change of the design drawing once created. Also in this case, the input receiving unit 11 outputs a drawing request signal in the same manner as described above.

  The user can add, change, and delete the position of the symbol with respect to the displayed design drawing. In addition, the input receiving unit 11 provides an indoor wiring simulation function, whereby the user clicks a switch on the design drawing to turn on or off the switch (for example, lighting of lighting). And off). The input receiving unit 11 outputs the edited design data or request data to the communication unit 12.

  The input receiving unit 11 further has a function of receiving an instruction for ordering a member related to indoor wiring based on the design drawing and the contents of the estimate. In this case, the input receiving unit 11 generates order information including a user ID, a request ID, a delivery date, a delivery location, and the like based on the user input, and outputs the ordering information to the communication unit 12.

  The communication unit 12 is a part that transmits and receives data to and from the design server 20. Specifically, the communication unit 12 transmits to the design server 20 request data including a user ID, a request ID, image data, facility data, section data, and property information input from the input receiving unit 11. When the edited design data is input, the communication unit 12 transmits the data to the design server 20 as request data. In addition, the communication unit 12 transmits a drawing request signal and ordering information, and receives design data and estimate data.

  Next, the design server 20 will be described. As shown in FIG. 2, the design server 20 includes a communication unit (reception unit) 21, a design unit (determination unit) 22, a price database 23, an estimation unit 24, a storage unit (storage unit) 25, and an ordering unit as functional components. 26, a factory database 27, and a data management unit 28.

  The hardware configuration of the design server 20 is the same as that shown in FIG. 3, and how each function of the design server 20 is realized on the hardware is the same as that described for the client terminal 10. However, the design server does not have to be a single piece of hardware, and each functional component is housed in separate hardware, and these hardware collectively perform the functions described below. Good. For example, when a server is configured with a rack, hardware may be divided according to function.

  The communication unit 21 is a part that transmits and receives data to and from the client terminal 10. Specifically, the communication unit 21 receives request data from the client terminal 10 and outputs it to the data management unit 28. In addition, the communication unit 21 outputs the received drawing request signal to the data management unit 28, and transmits design data and estimate data or request data input from the data management unit 28 to the client terminal 10 accordingly. Further, the communication unit 21 outputs the received ordering information to the ordering unit 26.

  The data management unit 28 is a part that manages various data. When request data is input from the communication unit 21, the data management unit 28 temporarily outputs the data to the storage unit 25 for storage. Subsequently, the data management unit 28 reads the request data from the storage unit 25 and outputs the request data to the design unit 22 to instruct the design unit 22 to generate design data.

  When a drawing request signal is input from the communication unit 21, the data management unit 28 reads design data and estimate data corresponding to the user ID and request ID included in the signal from the storage unit 25 and outputs them to the communication unit 21. To do. If design data and estimate data are not yet generated and do not exist in the storage unit 25, the data management unit 28 reads out request data corresponding to the user ID and the request ID from the storage unit 25 and outputs the request data to the communication unit 21. . In this case, wiring data to be described later is generated based on the corrected request data.

  The design unit 22 is a part that determines the wiring of the electrical equipment based on the request data input from the data management unit 28, and includes a CAD (Computer Aided Design) system. The design unit 22 determines the wiring of each electrical facility by applying the conventional wiring determination method to the drawing data, the facility data, and the section data, and for each wiring (each unit cable), the wiring identifier, the position ( Wiring data including coordinates) and length are generated. Then, the design unit 22 generates design data including the input request data and the generated wiring data, and outputs the design data to the estimation unit 24 and the storage unit 25. Specifically, the design unit 22 creates a branch circuit section, processes a connection between facilities, combines or divides sections, determines a starting point and a lowering point, unit cable wiring, distribution board layout, circuit connection Design data is generated by executing a series of processes including calculations.

  The design unit 22 generates design data in a CAD system file format such as DWG (Autodesk CAD software, AutoCAD standard file format. DraWinG), DXF (Drawing Interchange File), PDF (Portable Document Format), etc. To do. Alternatively, the design unit 22 generates design data by combining XML, Tiff, and the like. A drawing (indoor wiring diagram) can be obtained by drawing based on the design data. For example, when the request data of the equipment layout drawing K shown in FIG. 4 is input, the design unit 22 generates design data showing the design drawing of FIG. What is indicated by a symbol L in FIG. 5 is a wiring.

  When the edited design data is input as request data, the design unit 22 updates the wiring data by executing the above-described processing on the data (design change).

  The price database 23 is a part that stores data used for calculation in the construction cost of indoor wiring. Specifically, the price database 23 stores product data including types of electric equipment and unit cables and unit prices thereof in advance.

  The estimation unit 24 is a part that creates an estimate of the wiring of the electrical equipment based on the design data input from the design unit 22. The estimation unit 24 reads product data corresponding to each electrical equipment and each unit cable included in the design data, and calculates the amount of a member necessary for indoor wiring based on the equipment data, wiring data, and product data. Then, the estimation unit 24 generates estimation data including the calculation result, the user ID, and the request ID, and outputs the estimation data to the storage unit 25.

  In addition, the estimation unit 24 generates an e-mail indicating that the design and estimation of the indoor wiring has been completed, and transmits the e-mail to the user of the client terminal 10 via the communication unit 21. As a result, the user can know that the design drawing and the estimate have been created.

  The estimation unit 24 executes the same process as described above on the edited design data (re-estimation).

  The storage unit 25 is a part that stores request data input from the data management unit 28, design data input from the design unit 22, and estimation data input from the estimation unit 24.

  The ordering unit 26 is a part that executes ordering processing based on the ordering information input from the communication unit 21. The ordering unit 26 extracts design data corresponding to the user ID and the request ID included in the ordering information from the storage unit 25. Subsequently, the ordering unit 26 reads data from the factory database 27 storing the production capacity and operation status of each factory, and based on the data, which factory is requested to manufacture a product based on the design data. decide. Although this determination method is arbitrary, for example, the ordering unit 26 may select a factory with the lowest operating rate, or may select a factory located closest to the user. Subsequently, the ordering unit 26 transmits design data and ordering information to the factory terminal 30 of the selected factory.

  Next, the operation of the wiring design system 1 shown in FIG. 1 and the wiring design method according to the present embodiment will be described with reference to FIGS.

  First, a basic operation procedure not including a design change will be described with reference to FIG. In the client terminal 10, the input receiving unit 11 receives input of image data, facility data, section data, and property information (step S11, receiving step). Subsequently, the communication unit 12 transmits these data as request data to the design server 20 (step S12, transmission step).

  In the design server 20, the communication unit 21 receives the request data (step S13, reception step). Subsequently, the design unit 22 determines the wiring of each electrical facility based on the data, and generates design data (step S14, determination step). This design data is stored in the storage unit 25 (step S15, storage step). Subsequently, the estimation unit 24 generates estimation data based on the design data (step S16). This estimated data is also stored in the storage unit 25 (step S17).

  Thereafter, when the design is confirmed, the user of the client terminal 10 inputs ordering information. At this time, the input receiving unit 11 receives the order information, and the communication unit 12 transmits the information to the design server 20 (step S18). In the design server 20, the ordering unit 26 determines a factory for manufacturing the product (step S19), and transmits ordering information and design data to the factory terminal 30 of the selected factory (step S20). Thereafter, a product related to indoor wiring (for example, a unit cable) is manufactured at the selected factory and delivered to the user.

  Next, an operation procedure related to the design change will be described with reference to FIG. The processing in steps S31 to S35 in FIG. 7 is the same as the processing in steps S11 to S17. Thereafter, when the user of the client terminal 10 performs an operation for starting the design change, the input receiving unit 11 generates a drawing request signal, and the communication unit 12 transmits the signal to the design server 20 (step S36). In the design server 20, the data management unit 28 reads design data and estimate data or request data corresponding to the signal from the storage unit 25 (step S37), and the communication unit 21 transmits the data to the client terminal 10 (step S37). S38).

  In the client terminal 10, the input accepting unit 11 accepts editing of the received data (step S39, editing step). Subsequently, the communication unit 12 transmits the edited data as request data to the design server 20 (step S40, retransmission step). Thereafter, the processes in steps S41 to S43 executed by the design server 20 are the same as the processes in steps S33 to S35. Although FIG. 7 shows the case where step 36 is after step 35 for generating and storing estimated data, the processing of step 36 is executed at a time when design data has not yet been generated, that is, before step 34. Sometimes it is done. In that case, the data transmitted in step 38 becomes request data.

  The processes in steps S36 to S43 are repeatedly executed every time the user of the client terminal 10 makes a design change. When the design is finalized, the processes of steps S18 to S20 shown in FIG. 6 are executed based on the input of the user's ordering instruction.

  As described above, according to the present embodiment, the image of the floor plan and the installation location of the electrical equipment corresponding to the diagram are input via the input screen in the client terminal 10 and transmitted to the design server 20 as request data. . Subsequently, the design server 20 determines the wiring of the electrical equipment based on the request data and stores it as design data. As a result, compared to the conventional case where the user gives a drawing to the design company and requests the wiring design, and the designing company inputs not only the wiring but also the floor plan and the layout of the electrical equipment, the indoor wiring is compared. Design data can be completed early.

  Further, according to the present embodiment, the generated design data is acquired by the client terminal 10 and editing for the data is accepted. Then, the edited design data is transmitted to the design server 20 as request data. Thereby, in the design server 20, since wiring is determined with respect to the design data after edit, a design change can be implemented at an early stage.

  Further, according to the present embodiment, since the input screen D is provided to the user as a web application, the input screen can be easily mounted on the client terminal 10 by automatic download without requiring a special installation operation from the user. be able to.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.
