  FIG. 2 shows a flow of construction management by the construction management system 1 having such a configuration. As shown in FIG. 2, the flow of construction management by the construction management system 1 can be divided into a data generation stage, a site confirmation correction stage, a data reflection stage, and a record generation stage. The data generation stage is a stage (steps S1 to S3) in which the member object data is generated by the CAD device 4 in the office or the like, and the two-dimensional code is generated from the attribute data included in the member object data. On-site confirmation and correction stage: At the construction site, the mobile terminal device 3 restored the attribute data from the two-dimensional code, checked and changed the attribute data against the actual construction state, etc., and assembled into the equipment This is a stage (steps S4 to S10) in which attribute data obtained by taking a photograph of a member or the like and changing the image data and image data obtained by taking a photograph are sent as construction state data by mail. The data reflection step is a step of changing the design attribute data based on the construction state data transmitted from the mobile terminal device 3 and adding image data to the design attribute data (step) S11 to S12). The record generation stage is a stage (steps S13 to S14) of generating a construction record by using the construction state data by the record generation unit 6 in an office or the like.

  FIG. 3 shows the operation of the CAD device 4 in the data generation stage. The operation of the CAD device 4 at the data generation stage will be described with reference to FIGS.

  In the data generation stage, first, the user operates the keyboard and mouse of the personal computer 2 to create member object data by the CAD device 4. In accordance with the operation by the user, the CAD unit 7 of the CAD device 4 generates member object data and stores it in the memory of the personal computer 2 (step S1).

  In the member object generation process, the CAD unit 7 displays an image of the member object on the screen 21 of the monitor of the personal computer 2. In addition, when the user designates a member object with a mouse or the like, the CAD unit 7 identifies the designated member object from other member objects by changing the display mode of the image of the designated member object. It can be so. Further, the CAD unit 7 displays a member object window 22 in which attribute data of the designated member object is described. For example, in FIG. 3, the image of the member object 23 </ b> A specified by the user is displayed on the screen 21 in a display mode different from the images of the other member objects 23 </ b> B and 23 </ b> C, and the specified member A state in which the member object window 22 in which the attribute data of the object 23A is described is displayed. Further, as described above, the CAD unit 7 generates and stores member object data for each member. Each member object data includes member attribute data. FIG. 3 shows member object data 24A, 24B, and 24C of the member objects 23A, 23B, and 23C on the screen 21, and attribute data 25A, 25B, and 25C included therein, respectively.

  Next, the user operates the keyboard, mouse, etc. of the personal computer 2 to create a two-dimensional code corresponding to the attribute data of each member. According to the operation by the user, the encoding unit 8 of the CAD device 4 encodes the attribute data included in each member object data, generates a two-dimensional code corresponding to the attribute data, and stores it in the memory of the personal computer 2 (step) S2). FIG. 3 shows two-dimensional codes 26A, 26B, and 26C corresponding to the attribute data 25A, 25B, and 25C included in the member object data 24A, 24B, and 24C, respectively. The generation of the two-dimensional code may be performed when the individual member object data is designated by the user and an instruction to generate the two-dimensional code is input, or the generation of the member object data may be performed. It is good also as a structure performed automatically at the time.

  Next, the user operates a keyboard or a mouse of the personal computer 2 and a printer connected via the data input / output port of the personal computer 2 so that the two-dimensional code corresponding to the attribute data of each member is labeled on the label sheet. (Step S3).

  4 and 5 show the operation of the mobile terminal device 3 in the on-site confirmation correction stage, and FIG. 6 shows the item data stored in the memory of the mobile terminal device 3. The operation of the mobile terminal device 3 in the on-site confirmation / correction stage will now be described with reference to FIGS. 2 and 4 to 6.

  In the on-site confirmation and correction stage, first, the user goes to the construction site with the portable terminal device 3 and the label on which the two-dimensional code is printed, and performs construction work such as assembling members to the equipment. When the construction work is completed, or at an appropriate stage during the construction work, the user performs a work to check the construction state such as the assembly state of the members.

  In this confirmation operation, the user first attaches a label printed with a two-dimensional code corresponding to the attribute data of the member to the member.

  Subsequently, the user operates the mobile terminal device 3 to activate the construction management program stored in the memory of the mobile terminal device 3. In response to this, the CPU of the mobile terminal device 3 activates the construction management program and displays the login screen 31 on the display of the mobile terminal device 3. When the user operates the input key of the mobile terminal device 3 and inputs a predetermined user name and password, the CPU of the mobile terminal device 3 reads the user data stored in the memory of the mobile terminal device 3, The user name and password included in the user data are checked against the user name and password input by the user, and only when they match, the user is allowed to log in (step S4). When the login is permitted, the CPU of the mobile terminal device 3 switches the display on the display from the login screen 31 to the selection screen 32.

  Next, the user operates the input key of the mobile terminal device 3 or touches the touch panel when the mobile terminal device 3 includes a touch panel, and turns on the two-dimensional code reading button 33 in the selection screen 32. The two-dimensional code printed on the label affixed to the member is photographed with the camera of the mobile terminal device 3. At this time, the two-dimensional code 34 is displayed on the display of the mobile terminal device 3. In response to such user operation, the code reading unit 11 of the mobile terminal device 3 reads the two-dimensional code (step S5), and the decoding unit 12 of the mobile terminal device 3 decodes the read two-dimensional code. As a result, the attribute data corresponding to the two-dimensional code is restored and stored in the memory of the mobile terminal device 3 (step S6). Subsequently, the attribute data display unit 13 of the mobile terminal device 3 generates an attribute data display screen 35 in which the attribute data restored by the decoding unit 12 is described, and the attribute data display screen 35 is displayed on the display device of the mobile terminal device 3. (Step S7).

  Here, on the attribute data display screen 35, as shown in FIG. 5A, the attribute data restored by the decoding unit 12, that is, the attribute data on the design of the member to which the two-dimensional code is affixed has a predetermined layout. Arranged according to. That is, in the left column in the attribute data display screen 35, characters (site name, item, floor number, work area,...) Indicating the type of attribute data are arranged. In the middle column in the attribute data display screen 35, characters (XX building, housing joint, 10F, W1,...) Indicating the contents of the attribute data are arranged. Characters indicating the contents of the attribute data are described in the text input form 51. Thereby, the contents of the attribute data can be changed, deleted, or added according to the user's operation. A list display button 52 is arranged in the right column in the attribute data display screen 35.

  The user compares the attribute data displayed on the attribute data display screen 35 with the attribute of the actually constructed member and confirms whether or not they match. When the attribute data displayed on the attribute data display screen 35 is different from the actual member attribute, the user changes, deletes, or adds the attribute data.

  When changing the attribute data, the user operates the input key of the mobile terminal device 3, or touches the touch panel when the mobile terminal device 3 includes a touch panel, and the list corresponding to the attribute data to be changed. The display button 52 is turned on. In response to this, the attribute data changing unit 14 of the mobile terminal device 3 displays on the display a list in which options that can be selected as the attribute data are arranged. For example, as shown in FIG. 5 (2), when the attribute data to be changed is the “system name” of the system to which the member belongs, the attribute data changing unit 14 selects “cold water”, “hot water”, “cold / hot water”. , A list 53 in which options such as “cooling water” are arranged is displayed on the display.

  Here, the item data as shown in FIG. 6 is stored in the memory of the mobile terminal device 3. Item data is data in which choices that can be selected as attribute data are defined for each type of attribute data. The attribute data changing unit 14 generates and displays a list using the item data.

  After such a list is displayed, the user operates an input key of the mobile terminal device 3 or touches the touch panel to select a desired option in the list. In response to this, the attribute data changing unit 14 changes the content of the attribute data to the content indicated by the selected option (step S8). As a result, the content of the attribute data displayed on the display is changed to the content indicated by the selected option, and the content of the attribute data stored in the memory of the mobile terminal device 3 is also selected. It is changed to the contents to point to.
