A case where each database of the database 33F has been constructed will be described.

Next, the defect cause estimation model 13D according to this embodiment will be described with reference to FIG.

As shown in FIG. 10, the failure cause estimation model 13D according to this embodiment is a neural network including an input layer, a plurality of intermediate layers, and an output layer. The input layer of the failure cause estimating model 13D is input with a photographed image of a region whose cause of failure is to be estimated. The output layer of the defect cause estimation model 13D outputs a plurality of candidates for the cause of the defect occurring in the part corresponding to the input photographed image, together with the probability that each candidate is the cause. The failure cause estimating model 13D is obtained in advance by learning, as teacher data, a plurality of combinations of previously obtained photographed images of troubled parts and the causes of the troubles of the parts corresponding to the photographed images. ing. In this embodiment, a case where there are a plurality of defect cause candidates output from the defect cause estimation model 13D will be described. It is good also as a form which outputs only one.

Next, the operation of the construction support system 90 according to this embodiment will be described with reference to FIGS. 11 to 27. FIG. First, with reference to FIGS. 11 to 13, the operation of the construction support device 10 when executing construction plan creation processing, which is processing for creating a construction plan, will be described. In response to an instruction to execute the construction plan creation process being input to the construction support apparatus 10, the CPU 11 of the construction support apparatus 10 executes the construction plan creation program 13A, whereby the construction plan creation process shown in FIG. executed. In order to avoid complication, here, a case will be described in which a construction site (hereinafter referred to as a "planning target site") to be created as a construction plan is designated in advance.

In step 200 of FIG. 11, the acquiring unit 11A reads all information (hereinafter referred to as "required skill information") from the required skill information database 33A, and all information (hereinafter referred to as " (referred to as builder-specific skill information). Further, in step 200, the acquisition unit 11A reads all information (hereinafter referred to as "standard work time information for each builder") from the standard work time database for each builder 33C.

In the next step 202, the acquisition unit 11A reads out information on construction processes (hereinafter referred to as "construction process information") from the navigation information database 33F. In the next step 204, the acquisition unit 11A reads all information (hereinafter referred to as "construction schedule information") from the construction schedule information database 33D, and reads all information (hereinafter referred to as "construction plan information") from the construction plan information database 33E. ).

In the following description, the scheduled construction schedule corresponding to the planned site in the construction schedule information will be referred to as "planned schedule", and the dwelling type corresponding to the planned target site in the construction schedule information will be referred to as "planned dwelling type". Further, hereinafter, the number of houses corresponding to the planned target site in the construction schedule information will be referred to as the "planned number of houses", and the construction process indicated by the construction process information will be referred to as the "planned construction process".

In the next step 206, the creation unit 11B determines whether or not there is a schedule matching the planned schedule in the construction schedule included in the read construction plan information, so that there is no scheduled construction in the planned schedule. It is determined whether or not there is, and if the determination is negative, the process proceeds to step 210 , and if the determination is positive, the process proceeds to step 208 .

In step 208, the creation unit 11B identifies from the construction plan information a builder who will perform construction on the construction schedule determined in step 206 to match the schedule to be planned, ) is excluded from the current construction plan. In this embodiment, as the builder exclusion process, a process of temporarily storing the builder ID corresponding to the set builder in a predetermined area of the storage unit 13 is applied, but it is not limited to this. Needless to say. In addition, below, the builder except the set builder is called "a configurable builder."

In step 210, the creation unit 11B identifies the planned construction process from the read construction process information, and in the next step 212, the creation unit 11B determines the construction (unit bath in this embodiment) at the planned site. A construction plan will be prepared as shown below. In addition, in order to avoid confusion here, regarding the process of "confirmation that it has settled" in the construction process to be planned, subdivided processes such as "height measurement" and "window measurement" will not be considered, and It will be explained as a process summarized as "confirmation".

First, the creation unit 11B identifies the most important required skill corresponding to the type of house to be planned in the required skill information for each process of the construction process to be planned identified by the process of step 210 . For example, if the type of dwelling to be planned is an apartment complex, the most important required skill is "preciseness" for "confirmation of fit", and "construction speed" for "floor".

Next, the creating unit 11B applies a settable builder having a high skill value corresponding to the corresponding most important required skill as a construction candidate to each process of the specified construction process to be planned. In this case, it is allowed to apply a different configurable builder to the same construction process, and to apply the same configurable builder to a different construction process. In the present embodiment, a builder whose skill value indicated by the builder-specific skill information is a predetermined value (eg, 70) or more is applied as a settable builder with a high skill value. It is not limited. For example, among settable builders, a predetermined number of builders with the highest corresponding skill value may be applied as settable builders with high skill values.

In addition, the creation unit 11B identifies the standard work time corresponding to the fitted construction candidate for each process of the construction process to be planned from the standard work time information for each builder, and adds the number of homes to be planned to the identified standard work time. is multiplied by the value obtained by dividing by the number of construction candidates applied to the corresponding process, the work time required for each construction candidate to perform the process is calculated. Then, by summing up the work hours of each construction candidate for each process of the construction process to be planned, the estimated work time for each process that is expected to be spent on each process is calculated. The information indicating the construction candidate for each process and the estimated work time for each process for the planned construction process obtained by the above processing is referred to as "provisional plan information".

In the next step 214, the creation unit 11B determines whether or not the total work time of the construction process to be planned indicated by the tentative plan information obtained by the process of step 212 is within the range of the schedule to be planned, If the determination is affirmative, the process proceeds to step 216 .

At step 216, the creation unit 11B stores (registers) the provisional plan information obtained by the above processing in the construction plan information database 33E as information indicating the final construction plan corresponding to the site to be planned. In the next step 218, the creating unit 11B transmits information indicating the created construction plan to the terminal 20 owned by each builder via the communication I/F unit 18. FIG. In the next step 220, the creation unit 11B uses the created construction plan to control the display unit 15 to display a construction plan display screen in a predetermined format, and then the main construction plan creation process. exit.

As shown in FIG. 12, in this embodiment, as the construction plan display screen, construction candidates and process names corresponding to each process are in chronological order from left to right on the paper surface, and construction time zones ( Estimated work time for each process) is displayed so that you can see it. Therefore, the user of the construction support device 10 who refers to the construction plan display screen can easily grasp the steps to be performed by each builder and the time slot to perform the work.

Also, in the terminal 20 that has received the information indicating the construction plan, a construction plan display screen similar to that shown in FIG. 12 is displayed on the display unit 25 as an example. Therefore, the builder who refers to the construction plan display screen can easily grasp the process to be executed by himself and the time slot to be executed.

On the other hand, if a negative determination is made in step 214, the process proceeds to step 222, and the creation unit 11B determines whether or not there remains a settable builder that has not been applied in the immediately preceding fitting, thereby obtaining provisional plan information. It is determined whether or not there is room for the builder to be rearranged, and if the determination is affirmative, the process returns to step 212 . In step 212, which is executed following this process, the configurable builder is applied to each step of the construction process to be planned, including the remaining configurable builder.

On the other hand, if a negative determination is made in step 222, it is assumed that the required construction plan cannot be created with the current number of personnel, and the process proceeds to step 224. After controlling the display unit 15 to display the screen, this construction plan creation process is terminated.

As shown in FIG. 13, in this embodiment, as the personnel shortage display screen, the construction site, type of residence, scheduled construction schedule, skills and number of workers required for the shortage of workers, and shortage of time are displayed. . Therefore, the user of the construction support device 10 who refers to the personnel shortage display screen can efficiently add personnel, review the overall plan, etc. based on this information.

Next, referring to FIGS. 14 to 23, the construction support device 10 and the terminal when executing the process of supporting the work when each builder performs construction according to the construction plan created by the construction plan creation process. 20 will be described. In this case, the CPU 11 of the construction support device 10 executes the construction support program 13B in response to input of an instruction to execute the construction support processing to the construction support device 10, whereby the construction support processing shown in FIG. executed. Further, in this case, the CPU 21 of the terminal 20 executes the navigation program 23A in response to the execution instruction of the navigation processing being input to the terminal 20 by the builder, thereby executing the navigation processing shown in FIG. be. First, with reference to FIG. 14, the operation of the construction support device 10 when executing the construction support process will be described.

Each builder who carries out construction in accordance with the construction plan created by the construction plan creation process goes to the construction site where he/she will carry out the construction, and causes his/her own terminal 20 to perform navigation processing, as will be described later. Then, in this navigation processing, the builder transmits navigation request information for requesting a navigation service to the construction support device 10 together with site information indicating the construction site, his/her own builder ID, and language information indicating the language to be used. to perform the operation.

Therefore, in step 300 of FIG. 14, the presenting unit 11G waits until the navigation service is requested from any terminal 20 by waiting until navigation request information is received from any terminal 20. FIG. Hereinafter, the terminal 20 from which the received navigation request information is transmitted will be referred to as a "corresponding target terminal", and the builder who owns the corresponding corresponding terminal will be referred to as a "corresponding target builder".

In the next step 302, the presentation unit 11G reads all information (hereinafter referred to as "navigation information") from the navigation information database 33F. In the next step 304, the presentation unit 11G uses the read navigation information to create information indicating a navigation screen in a predetermined format (hereinafter referred to as "navigation screen information"). In the next step 306, the presentation unit 11G transmits the created navigation screen information to the corresponding target terminal via the communication I/F unit 18. FIG. At this time, the presentation unit 11G creates navigation screen information indicating a navigation screen corresponding to the language indicated by the language information received together with the navigation request information. Also, at this time, the presentation unit 11G creates navigation screen information as information indicating a plurality of screens, each of which has a different page for each process indicated by the read navigation information.

When the navigation screen information is received, the corresponding target terminal uses the received navigation screen information to control so that the navigation screens shown in FIGS. 17 to 20, which will be described later, shown in FIGS. do. When the navigation screen is displayed on the target terminal, the target terminal displays measurement result information indicating the measurement result of the position of each part in the "confirmation of completion" process according to the operation by the target builder, as described later. , inspection result information indicating the inspection result for the construction performed in the process related to the installation of the construction object (in this embodiment, the unit bath), and individual process end information indicating that the individual process is completed are transmitted to the construction support device 10. do. Note that in the present embodiment, individual process end information indicating that the immediately preceding process has ended is transmitted to the construction support apparatus 10 when a designation input designating the execution start of the next process is received on the navigation screen. However, it is not limited to this. For example, assume that the navigation screen accepts a specified input designating the end of the process when each process is completed, and when the specified input is accepted, individual process end information indicating that the process has been completed is displayed. A form of transmission to the construction support apparatus 10 may be adopted.

Therefore, in the next step 308, the reception unit 11H determines whether or not the measurement result information has been received from the terminal to be handled. At step 310, the reception unit 11H stores the received measurement result information in a predetermined area of the storage unit 13, and then proceeds to step 316. FIG.

On the other hand, if a negative determination is made in step 308, the process proceeds to step 312. The reception unit 11H determines whether or not inspection result information has been received from the corresponding terminal. On the other hand, if the determination is affirmative, the process proceeds to step 314 . At step 314 , the reception unit 11</b>H stores the received test result information in a predetermined area of the storage unit 13 , and then proceeds to step 316 .

At step 316, the delay estimator 11C determines whether or not individual process end information has been received from the terminal to be handled. At this time, if a plurality of builders are applied to the process corresponding to the individual process end information, the delay estimation unit 11C determines whether or not the final individual process end information for the process has been received. judge.

In step 318, the delay estimator 11C determines whether the process indicated by the received individual process end information (hereinafter referred to as the "end process") was completed within a predetermined time (10 minutes in this embodiment) from the schedule. judge. If the determination is affirmative here, the delay estimating unit 11C proceeds to step 336. If the determination is negative, the construction to be supported is delayed from the construction time planned in the construction plan. It is assumed that it is, and the process proceeds to step 320 . In this embodiment, it is determined whether or not the completion process is completed within a predetermined time from the schedule as follows.

That is, the delay estimating unit 11C refers to the end time in the construction schedule of the corresponding process in the construction plan information database 33E, and the time at which the individual process end information is received is within the predetermined time with respect to the end time. By judging whether or not there is, it is judged whether or not the ending process has been completed within a predetermined time from the schedule.

At step 320, the instruction unit 11D determines whether or not there is a qualified construction worker who does not engage in the remaining process for the process after the ending process (hereinafter referred to as the "remaining process"), and makes an affirmative determination. If not, go to step 322 . In addition, in this embodiment, the determination as to whether or not there is a qualified construction worker is performed as follows.

That is, the instruction unit 11D first refers to the construction plan information database 33E and specifies a builder (hereinafter referred to as a "suitable construction candidate") other than the builder who is engaged in the remaining processes. Next, the instruction unit 11D refers to the required skill information database 33A to specify the most important required skills for the remaining processes, and there are construction qualified candidates with high skill values corresponding to the specified most important required skills. By determining whether or not, it is determined whether or not the above-mentioned construction qualified person exists. Note that, in the present embodiment, a suitable construction candidate with a high skill value is a construction candidate with a corresponding skill value of a predetermined value (eg, 70) or more specified by the builder-specific skill information database 33B. However, it goes without saying that it is not limited to this.

In step 322, the instruction unit 11D transmits support instruction information for instructing support for the construction of the remaining steps to the terminal 20 of the qualified worker via the communication I/F unit 18 together with information indicating the content of the support. Upon receiving the support instruction information, the terminal 20 executes a support process (see FIG. 22), which will be described later, and displays, as an example, a support request screen (details will be described later) shown in FIG. Then, the builder whose support request screen is displayed on the terminal 20 specifies whether or not to provide support on the support request screen, thereby providing support status information indicating whether or not to provide construction support. It is transmitted to the device 10, and the assistance displayed on the assistance request screen is provided. Here, in order to avoid complication, the case where at least one person qualified for construction provides support will be described.

Therefore, in the next step 324, the changing unit 11E waits until the support status information is received from all the terminals 20 that have transmitted the support instruction information. Then, using the received support status information, the changing unit 11E changes the corresponding construction plan in the construction plan information database 33E so as to reflect that the construction qualified person who provides support is engaged in the remaining processes, After that, the process proceeds to step 328 .

On the other hand, if a negative determination is made in step 320, the process proceeds to step 326, and the changing unit 11E changes the end time of the end process to the actual end time, and also changes the construction schedule of the remaining process to that of the end process. The corresponding construction plan in the construction plan information database 33E is changed so as to move forward sequentially according to the actual end time, and then the process proceeds to step 328.

In step 328 , the change unit 11</b>E transmits information indicating the construction plan after the change to the terminal 20 of the builder who is engaged in the corresponding construction, and then proceeds to step 336 . The terminal 20 that has received the information indicating the construction plan after change displays the information indicating the construction plan after the change on the display unit 25 . Therefore, by referring to this display, the builder who is carrying out the corresponding construction can grasp the change of the construction plan which he/she is carrying out or is planning to carry out.

On the other hand, if a negative determination is made in step 316, the process proceeds to step 330, and the detection unit 11F determines whether or not the work efficiency of the construction process being executed is below a predetermined level. It is determined whether or not the process in progress has passed, and if the determination is negative, the process returns to step 308 , and if the determination is positive, the process proceeds to step 332 . In addition, in this embodiment, the reference time is determined as follows.

That is, the detection unit 11F first determines the standard work time of the corresponding construction process for all workers engaged in the construction process in progress (hereinafter referred to as "engaged workers"). Read from time database 33C. Next, the detection unit 11F multiplies the read standard work time by the number of times the corresponding construction process is performed by the corresponding engaged builder for each engaged builder. Then, the detection unit 11F sets the maximum construction time for each engaged construction worker obtained by the above calculation as the reference time. However, the present invention is not limited to this form, and for example, a form in which a time obtained by multiplying the maximum time by a predetermined coefficient (for example, 1.2) is applied as the reference time.

At step 332, the presentation unit 11G extracts an advice sentence and an advice voice corresponding to the corresponding construction process from the read navigation information, and uses the extracted advice sentence to display an advice screen in a predetermined format. Create advisory screen information to show. Then, in the next step 334, the presentation unit 11G transmits the created advice screen information and the extracted advice voice to the terminal 20 of the engaged builder via the communication I/F unit 18, and then returns to step 308. . When the advice screen information and the advice voice are received, the terminal 20 displays the advice screen shown in FIG. 21 as an example (details will be described later) on the display unit 25 and reproduces the advice voice. In response to this, the builder whose advice screen is displayed on the terminal 20 tries to practice the advice displayed on the advice screen. As described above, the information indicated by the advice is information indicating know-how for improving work efficiency obtained by a skilled builder when performing the corresponding construction. Therefore, by practicing the advice displayed on the advice screen, an effect of improving the work efficiency for the corresponding construction process can be expected.

On the other hand, in step 336, the presentation unit 11G determines whether or not all construction work except for the process of "inspection table confirmation" at the corresponding site has been completed. When the determination is affirmative, the process proceeds to step 338 .

At step 338, the presentation unit 11G uses the inspection result information stored in the storage unit 13 in the above process to display an inspection table screen in a predetermined format including all inspection results. Create screen information. Then, in the next step 340, the presentation unit 11G transmits the created inspection sheet screen information to the terminal 20 of the builder who carries out the step of "inspection sheet confirmation" in the corresponding construction via the communication I/F unit 18. send and then go to step 342 . Upon receiving the inspection chart screen information, the terminal 20 displays an inspection chart screen (not shown) on the display unit 25 . Then, the builder whose inspection table screen is displayed on the terminal 20 confirms the inspection result of each process displayed on the inspection table screen, and then sends the inspection result confirmation information indicating that the confirmation has been performed. Send to device 10 .

Therefore, in step 342, the reception unit 11H waits until it receives the inspection result confirmation information, and in the next step 344, the reception unit 11H stores (registers) the corresponding inspection result information in the inspection result database 33G, After that, the construction support processing is terminated.

Next, with reference to FIG. 15, operation of the terminal 20 when executing navigation processing will be described. Here, the operation of the terminal 20 possessed by the builder who carries out the step of "confirmation of the inspection sheet" will be described.

At step 400 in FIG. 15, the control unit 21A controls the display unit 25 to display a predetermined initial screen. stand by. FIG. 16 shows an initial screen according to this embodiment. As shown in FIG. 16, on the initial screen according to the present embodiment, a selection area 25A for selecting a language to be applied on the navigation screen is provided, and a navigation service start language specified when instructing execution of the navigation service is provided. Button 25B is displayed. When the initial screen shown in FIG. 16 is displayed, the builder designates a button displaying the language name to be applied on the navigation screen, and then designates the navigation service start button 25B. When the navigation service start button 25B is designated, step 402 becomes affirmative determination and the process proceeds to step 404 .

At step 404, the control unit 21A sends the navigation request information described above to the construction support device 10 via the wireless communication unit 27 together with the site information indicating the construction site, the own builder ID, and the language information indicating the language to be used. Send. As described above, upon receiving the navigation request information, the construction support device 10 transmits the navigation screen information indicating the navigation screen to the terminal 20 .

Therefore, in the next step 406, the control section 21A waits until the navigation screen information is received. The display unit 25 is controlled to start displaying from .

By the above control, the navigation screens shown in FIGS. 17 to 20 are sequentially displayed on the display unit 25 of the terminal 20 as described above. Note that the navigation screen 25C shown in FIG. 17 is an example of a navigation screen relating to the measurement of "bottom surface to bottom inner surface of frame", which is a part of the "window measurement" process in the "settling confirmation" process. Further, the navigation screen 25D shown in FIG. 18 is an input area for inputting the measurement results in the process displayed on the navigation screen 25C shown in FIG. 25E is an example of a navigation screen. The builder who refers to these navigation screens performs measurements according to the display contents of the referred navigation screens, and inputs the measurement results into the input area 25E.

A navigation screen 25F shown in FIG. 19 is an example of a navigation screen displayed when starting the process of installing the "bathtub". As described above, in the present embodiment, when a designation input designating the execution start of the next process is accepted on the navigation screen, the construction support apparatus outputs the individual process end information indicating that the immediately preceding process has ended. Sent to 10. Therefore, on the navigation screen 25F shown in FIG. 19, a bathtub construction start button 25G that is specified when starting construction of a bathtub is displayed, and the builder presses the bathtub construction start button 25G when starting construction of a bathtub. specify.

Furthermore, a navigation screen 25H shown in FIG. 20 is an example of a navigation screen displayed in the process of "inspection of waterproof pan joint". On the navigation screen 25H shown in FIG. 20, a photographed image obtained by actually photographing a region similar to the region to be inspected is displayed as a model photograph. Further, on the navigation screen 25H, a photographed image area 25I in which an image photographed by the camera 28 of the terminal 20 is displayed, and a photographing button 25J designated when photographing is displayed. Therefore, the builder sets the enlargement magnification and positions the terminal 20 so that the composition of the photographed image displayed in the photographed image area 25I substantially matches the composition of the model photograph, and then presses the photographing button 25J. Specify By this operation, it is possible to take an inspection image of the construction object very accurately. The navigation screen for inputting inspection results is not limited to the one for inputting the photographed image shown in FIG. 20 as an example. Needless to say, there is also a navigation screen to enter.

Each image on the navigation screens shown in FIGS. 17 to 20 is based on the "description image" in the navigation information. Also, the text information on the navigation screens shown in FIGS. 17 to 20 is based on the "description" in the navigation information.

In the next step 410, the control unit 21A determines whether any of the measurement result, the inspection result, and the designation input designating the execution start of the next process has been input to the displayed navigation screen. is determined, and if a negative determination is made, the process proceeds to step 412 .

As described above, in the construction support processing according to the present embodiment, when the reference time has passed for a process being executed, it is assumed that the work efficiency in the process is below a predetermined level, and the advice screen information is displayed. and advice voice are transmitted from the construction support device 10 .

Therefore, in step 412, the control unit 21A determines whether or not the advice screen information has been received from the construction support device 10. If the determination is negative, the process returns to step 410. Go to 414.

At step 414, the control unit 21A controls the display unit 25 so as to display the advice screen indicated by the received advice screen information, and also controls the speaker 41 so as to output the advice voice received together with the advice screen information. control and then return to step 410 . FIG. 21 shows an example of an advice screen 25K according to this embodiment. The advice screen 25K shown in FIG. 21 displays text information indicating advice. In addition, in the present embodiment, when the advice screen 25K is displayed, as schematically shown in FIG. Therefore, the builder can more effectively improve work efficiency by using the text information and voice advice.

Note that, on the advice screen 25K according to the present embodiment, as shown in FIG. 21 as an example, an end button 25M designated when ending the display of the advice screen 25K is displayed. Accordingly, the builder designates the end button 25M when ending the display of the advice screen. In response, the display unit 25 of the terminal 20 displays the navigation screen that was displayed immediately before the advice screen was displayed.

On the other hand, if the determination in step 410 is affirmative, the process proceeds to step 416, and the control unit 21A determines whether or not the measurement result has been input to the displayed navigation screen. goes to step 418 .

At step 418, the control unit 21A transmits measurement result information indicating the measurement result input on the navigation screen to the construction support device 10 via the wireless communication unit 27, and then proceeds to step 420. If the determination in step 416 is negative, the process proceeds to step 420 without executing the process of step 418 . Upon receiving the measurement result information, the construction support device 10 stores the received measurement result information in the predetermined area of the storage unit 13 as described above.

At step 420, the control unit 21A determines whether or not a test result has been input to the displayed navigation screen.

In step 422, the control unit 21A transmits inspection result information indicating the inspection result input on the navigation screen to the construction support device 10 via the wireless communication unit 27, and then proceeds to step 424. Here, when transmitting a photographed image of a region to be inspected, the control unit 21A sets the photographing time as the examination date and time, and sets the photographing position detected by the position detecting unit 40 at the time of photographing as the examination place. , these pieces of information are transmitted to the construction support apparatus 10 as accompanying information of the captured image. If the determination in step 420 is negative, the process proceeds to step 424 without executing the process of step 422 . Upon receiving the inspection result information, the construction support device 10 stores the received inspection result information in the predetermined area of the storage unit 13 as described above.

At step 424, the control unit 21A determines whether or not an instruction to start construction of the next step (for example, an instruction by specifying the bathtub construction start button 25G) has been input to the displayed navigation screen. If the determination is affirmative, the process proceeds to step 426 .

In step 426, the control unit 21A transmits individual process end information indicating that the process executed immediately before the process whose start of construction was instructed on the navigation screen to the construction support device 10 via the wireless communication unit 27. to send.
