Fourth step T4: Stage in which the designer in charge stores the drawing in the book management system First, the drawing specification data of interest is written out from the drawing specification information DB incorporated in the CAD system 55 and stored in the book management system (step). T41).

  FIG. 4i shows a display example of drawing specification data.

  Next, the temporary development DB is input. That is, the drawing specification data is automatically read and the drawing specification data is automatically copied to the production specification information DB incorporated in the order sales management system 60 (step T42).

  Next, the installation drawing and the design drawing are collectively stored for each building in the library DB (step T43).

  FIG. 4 j shows an example of a storage drawing list.

Fifth step T5: A stage where the construction worker enters production information (customer request ordering stage)
First, a customer request is received as a customer request ordering stage. Here, final specifications such as additional specifications are presented (step T51).

  Next, the production specification information DB is input. That is, the production information is input to the order sales management system 60 based on the customer request. FIG. 4k is an example of a production information input menu, and FIG. 4l is a submenu of FIG. 4k.

  The copy is automatically copied to the estimated specification information DB incorporated in the specification decision support system 52 (step T52).

  Next, the consistency of the production information is automatically checked using the specification determination rule DB (step T14). FIG. 4m is an example of a state in which production information is stored.

Sixth step T6: The construction information for which the construction person in charge decides the production information is written to the manufacturing system (step T61). Based on this, the manufacture of the elevator is started.

  According to the first embodiment, the consistency between the specification data and each drawing information of the manufacturing drawing, installation drawing or design drawing of the elevator and the contents of the database is achieved, so the specification of the elevator generated due to dependence on the human system. The lack of consistency or inconsistency between data and data such as manufacturing design can be eliminated, and the labor for checking the drawings manually can be reduced.

  FIG. 2 shows the contents of customer drawing information, and shows the drawing number of the elevator for each customer, the specification of the elevator, the name of the equipment used in the elevator, for example, the model number of the hoist used.

  When an input / output device selects and instructs the elevator of the customer information menu and the corresponding item of the installation information of the installation work menu indicating the type of installation information, the corresponding installation information is read from the installation drawing information and displayed on the screen. . That is, when the main rope is instructed from the customer information menu and the installation method is instructed from the installation operation menu, the main rope installation information is displayed from the installation drawing information. Here, the actual value of the loaded load is input.

  When these values do not conform to the installation standards recorded separately in the installation drawing information, this is displayed and the maintenance standards are shown. The maintenance drawing designer corrects the maintenance drawing according to the illustrated maintenance standard and then inputs the actual measurement value again.

  FIG. 5 is a flowchart for explaining the operation of the design and manufacturing support system according to the second embodiment of the present invention. The overall system configuration and functional structure are the same as those shown in FIGS. In FIG. 5, the person in charge of design first inputs a drawing name and specification data. The input data is transmitted to the host computer 30 via the network 33. In the host computer 30, the input data is compared with a search condition registered in advance.

  The storage device 31 of the host computer 30 stores in advance a design, design, manufacturing, installation / adjustment, and maintenance constraint information in a database of manufacturing design data, and the design drawing is edited by a drawing creation / editing device. In the creation stage, these constraint conditions are checked, and if there is a contradiction, an alarm is issued to the specification data input terminal.

  In addition to the constraint conditions, the search conditions include, for example, the relationship between cost and budget, selection of standard parts, selection of standard design drawings and installation drawings, and the like.

  In response to the response from the host computer 30, the control device 32 displays the elevator's manufacturing constraints and contract conditions (copyright, usage fee, etc.) unique to the elevator. Select (step U1).

  That is, the control device 32 sends the elevator manufacturing drawing designated by the input / output device 35 to the host computer 30 via the network 33. Then, the manufacturing drawing information stored in the input information of the storage device 31 is downloaded via the network 33, and the contents are displayed on the input / output device 35. The person in charge of design selects a drawing that meets various conditions from the displayed contents.

  Next, the person in charge of design inputs creation data such as a manufacturing drawing that satisfies the constraint conditions via the input / output device 35 (step U2). The created manufacturing drawing data and conditions for using the drawing are transmitted to the manufacturing system 26 in the host computer 30. That is, when the person in charge of the design creates and edits the drawing and clicks the “Send” button, the data such as the inputted person in charge of the design and the design drawing are transmitted to the host computer 30 through the network 33 together with the drawing. . The host computer 30 temporarily stores the data transmitted from the control device 32 in the storage device 31.

  Next, based on the check information in the storage device 31, the host computer 30 checks the sent drawings for restrictions on the elevator and usage conditions of the drawings (step U 3).

  Subsequently, if the restrictions and usage conditions of the elevator are satisfied, the design drawing data corresponding to the determined drawing is taken out from the storage device 31 (step U4).

  Here, if there is a problem with the restrictions and usage conditions of the elevator, for example, a warning is issued.

  The extracted design drawing data is sent to the manufacturing system 26 together with product information. The manufacturing system 26 arranges the manufacturing of the elevator based on the transmitted design drawing data.

  In the design / manufacturing support system of this embodiment, drawings for each part of the elevator are also stored in the storage device 31 after being classified in advance. Therefore, when a plurality of parts such as a ceiling and a panel are listed, various combinations of the parts listed based on the drawing desired by the customer can be combined to present some overall drawings.

  According to the second embodiment, since specification data and manufacturing design data including elevator manufacturing drawings, installation drawings, or design drawings are created without human intervention, the specification data of the elevator generated due to dependence on human systems and It is possible to eliminate a lack of consistency or contradiction with data such as manufacturing design, and to reduce the labor of checking the drawings manually.

  FIG. 6 is a flowchart for explaining the operation of the design and manufacturing support system according to the third embodiment of the present invention.

  In this embodiment, the storage device 31 has elevator design constraint conditions (dimensions, shape, color, etc.) necessary for drawing, and contract conditions between the designer (design company 45) and the management company 44, such as copyright attribution. Information, manufacturing drawing data, drawing management information of parts related to each drawing, and product information such as processing information are stored.

  The host computer 30 displays the elevator design constraint conditions according to the designated elevator manufacturing drawing, and the designer selects a drawing to meet the condition (step V1). Next, the contract conditions (copyright, usage fee, etc.) are displayed (step V2). Next, when the elevator design drawing is designated by the input / output device 35, the manufacturing drawing stored in the input information of the storage device 31 is transmitted to the control device 32 of the design company 45 through the network 33 (step V3). ). The person in charge of design selects these drawings and performs the drawing work (step V4).

  Next, after the designer completes the design, the use of the drawing is registered. As a result, the management company 44 obtains permission for the use of the drawing. In addition, it is preferable that the management company 44 and the design company 45 separately formally contract for use of the drawing (step V5).

  As described above, a new drawing library is constructed in the database owned by the management company 44. After such a procedure, the management company 44 receives an order for an elevator from the design company 45 (step V6).

  Next, as described above, the management company 44 presents the drawing or design manufacturing data to the design company 45 (step V7). The design company determines the elevator specifications based on the drawings and design / manufacturing data, and sends it to the management company 44 (step V8). The management company 44 estimates based on the sent specification data and submits it to the customer (step V9). The customer determines this estimate, places a contract with the management company 44, and places an order (step V10).
