  The present invention will be described below with reference to an embodiment.

  FIG. 1 shows a system configuration diagram of an embodiment. In the illustrated system, a server computer (hereinafter abbreviated as a server) 1 constituting quality control means installed on the management center side, a mobile communication network, etc. It is basically composed of a network terminal (hereinafter abbreviated as a terminal) 3 owned by a contractor for transferring data to and from the server 1 via the network 2, and the terminal 3 has a digital camera function. A personal computer, a PDA, or the like having a communication function that can read image data captured by a digital camera or a digital camera and can be remotely connected to the server 1 through the network 2. A program necessary as a terminal of the management system is installed and executed. In the after-sales service described later, a similar terminal 3 'owned by the owner is used.

  On the other hand, the server 1 includes a storage unit 10 for storing design data to be described later, a storage unit 11 for storing data to be described later, an arithmetic processing unit 12 for processing data for quality control, and a public including a mobile communication network. The communication processing unit 13 includes a modem having a transmission / reception function for transmitting and receiving data to and from the terminal 3 (or 3 ′) through the network 2 including a line network. Image data generation means 120 for generating still image data, shooting position detection means 121 for detecting the shooting position and shooting direction of the image indicated by the imaging data sent from the network terminal 3, and construction state analysis for analyzing construction quality The means 122, the report output means 123, and the cam-up means 124 are realized by executing a program. It has the reading and writing of the processing function that.

  Here, the design data stored in the database of the storage unit 10 is made up of design data registered for each product number of the house equipment to be managed, including the three-dimensional shape of each component of the house equipment. Model data, standard process chart, etc. In addition, the data stored in the storage unit 11 is the owner's basic data registered for each construction work number {[owner's name, owner's contact information, family coexistence, construction site type (whether it is home), new construction extension / renovation] Data on owners such as)], basic data of installers [(data on installers such as the name of the installer, contact information of the installers, the number of workers, years of experience, etc.), construction specification data (product number for construction, construction drawings) (Floor plan, delivery plan, design data for windows, entrances, etc. existing at the place where the housing equipment is installed, floor of construction site <1st floor or above), component specifications (part types, presence / absence of optional parts) Etc.)], construction point-in-time data (construction creation date and time, weather at the time of creation, imaging data showing the construction state, and additional data consisting of text data created by the installer regarding the imaging data)}.

 Next, a process for checking the construction state at the completion of construction will be described with reference to FIG. Note that a camera-equipped mobile phone is used as the terminal 3.

  First, the contractor images the construction site with a digital camera attached to the terminal 3 and inputs additional data related to the imaged data as text data. Both data are sent to the server 3 as construction data via the network 2. -Make a call (step S1). As additional data, for example, a transmission date and time, a contractor number for identifying a contractor, and a product number of a construction target are input.

  When the transmitted construction data is received by the communication unit 13 (step S2), the server 1 stores the construction data received under the control of the arithmetic processing unit 12 in the storage unit 11 (step S3). The arithmetic processing unit 12 takes in the received construction data (step S4), and extracts the product number of the construction target from the additional data (step S5). Then, the design data of the target house equipment stored in the storage unit 10 is searched with the extracted product part number (step S6), and the design data matching the product part number is searched from the design data stored in the storage unit 10. Select (step S7). Further, the model data of the three-dimensional shape of the component parts included in the selected design data is extracted (step S8). The image data generation means 120 of the arithmetic processing unit 12 generates a plurality of still image data composed of virtual computer graphics as viewed from various angles of the house equipment assembled with the extracted model data (step). S9). Next, the shooting position detection means 121 of the arithmetic processing unit 12 detects the angle (line-of-sight direction) for viewing the image indicated by the imaging data, that is, the shooting position and the shooting direction, based on the plurality of generated still image data. The selected still image data having the same shooting position and shooting direction is selected (step S10), and the construction state analyzing means 122 compares the selected still image data with the imaging data by using a known pattern recognition method to obtain individual components. Differences such as position and assembly angle are detected (step S11), and the difference detection result is output as a report file by the report output means 123 (step S12).

  An example of recognition using the pattern recognition method will be briefly described with reference to FIG. For example, when image A in FIG. 3A is true and image B is compared with image B in FIG. 3B, the black portion of image A does not exist in image B. It can be considered that there is no part, that is, forgetting to attach parts. On the other hand, comparing the image C and the image A in FIG. 3C, when 30% of the area of the black portion of the image A is also a black portion in the image C, as shown in FIG. When the black part is made gray and this gray part (A) and the black part (B) of image A are overlapped, there is a deviation between the gray part (A) and the black part (B). I understand. Here, in the image C, if the black part is 0 to 10%, forgetting to attach a part, and if it is 10 to 70%, the mounting position shift is determined in advance. Can be verified. If both the imaged data and the still image data are binarized and the pattern recognition process as described above is performed, the analysis process can be performed more quickly.

  As described above, the output report file is stored in addition to the construction data stored in the storage unit 11 (step S13), and the communication unit 13 makes a call to the corresponding terminal 3 through the network 2. It is transmitted (S14). When the terminal 3 receives the transmitted report file, the terminal 3 displays the content on the display. The construction person can improve the construction quality to a required level by correcting the construction contents in accordance with the indications such as the differences indicated in the report file (step S15).

  Although the example in the case of performing construction quality check at the time of completion of construction has been described with reference to FIG. 2, for example, processing for enabling quality check during construction will be described with reference to FIG. 4.

  In FIG. 4, the contractor calls / transmits the construction time data from the terminal 3 to the server 1 through the network 2 at a scheduled time (step S1). The construction time data is based on image data taken from the construction site at that time and additional data consisting of text data such as comments such as cautionary notes, construction work numbers to be processed, and construction process numbers indicating the construction process at that time. Composed.

  When the server 1 receives the received construction time data by the communication unit 13 (step S2), the construction time data is stored in the storage unit 11 under the arithmetic processing unit 12 (step S3) and analyzed (step S3). ') The construction work number is extracted from the additional data by this analysis (step S4), and the stored data in the storage unit 11 is searched with this construction work number (step S5). From this search, the construction work data and construction specification data matching the construction work number are selected from the stored data (step S6), and the product number of the construction target is extracted from the construction specification data (step S7). Thus, the design data in the storage unit 10 is searched (step S8). Design data that matches by this search is selected from the stored data in the storage unit 10 (step S9), and model data of the three-dimensional shape of the part included in the selected design data is extracted (step S10). Based on the extracted model data, the processing by the image data generation means 120, the photographing position detection means 121, the construction state analysis means 122, and the report output means 123 of the arithmetic processing unit 12 is performed in steps S11 to S14. This processing corresponds to the processing in steps S9 to S12 in FIG.

  The arithmetic processing unit 12 extracts the construction process number from the additional data stored in the storage unit 11 (step S15), and searches the construction work data by the construction process number with a number one lower than the construction process number (step S15). S16), data other than the number data among the construction time data sent this time is stored in the subsequent part of the construction work data of the retrieved construction process number (step S17). Then, under the control of the arithmetic processing unit 12, the report file output from the report output unit 123 is additionally stored in a portion following the data stored in the storage unit 11 in step S16 (step S18). Further, one is added to the count value of the assignment counter to the part and part where the difference is detected, and the value is written as a priority flag in the design data in the corresponding storage unit 10 (step S19). Further, the report file is called and transmitted to the corresponding terminal 3 through the communication unit 13 (step S20).

  The priority flag indicates a part to which the comparison process in the construction state analyzing unit 122 is prioritized, and the construction state analyzing unit 122 starts a process of comparing from the part of the part data including the priority flag. The processing is preferentially performed in descending order of the count value.

  Now, when the terminal 3 receives the transmitted report file, the contents are displayed on the display, and the construction person is required to have the construction quality by correcting the construction contents in accordance with the pointed out matters such as differences shown in the report file. The level can be increased (step S21).

  Thus, the quality of the construction state in the middle of construction can be improved by checking the construction state in the middle of construction by the procedure shown in FIG.

  2 and 4 above show the processing in the case of the quality check of the construction state. However, in the system of this embodiment, when the construction is not successful in the middle of construction, a trouble example from the builder side to the server 1 side. It is also possible to request countermeasures and image data of good construction examples.

  The processing in this case will be described with reference to FIG.

  First, when construction is not successful in the middle of construction, the construction person calls and sends construction inquiry data at that time from the terminal 3 to the server 1 through the network 2 (step S1). The construction inquiry data is composed of imaging data obtained by photographing a corresponding part where construction is not successful during construction, and additional data including comments such as notes, construction work numbers, construction process numbers, and the like.

  Now, when the server 2 receives the construction inquiry data from the terminal 3 by the communication unit 13 (step S2), the arithmetic processing unit 12 takes in and analyzes the construction inquiry data (step S3). A work number is extracted (step S4). The stored data in the storage unit 11 is searched with the extracted construction work number (step S5). The arithmetic processing unit 12 further selects construction work data, construction specification data, and the like that match the construction work number stored in the storage unit 11 by this search (step S6), and the construction target data is selected from the selected construction specification data. The product number of the housing equipment is extracted (step S7). The stored data in the storage unit 10 is searched with the extracted product item number (step S8), and a standard process chart that matches the product item number is selected (step S9). Further, the arithmetic processing unit 12 extracts the construction process number from the additional data (step S10), searches the selected standard process table by this construction process number (step S11), and this search results in the process schedule from the standard process table. A construction procedure, trouble cases and countermeasures for the main construction, image data of a photograph showing a good construction case, and the like are extracted (step S12). Further, the part related to the construction and the count value of the counter assigned to the part are incremented by one and written as a priority flag in the design data (step S13).

  Further, the report output means 123 of the arithmetic processing unit 12 collectively outputs the results extracted in step S10 as a report file (step S14). This report file is additionally stored in the data stored in the storage unit 11 (step S15). Moreover, it transmits to the terminal 3 which sent construction inquiry data via the communication part 13 (step S16). The terminal 3 displays the report file on the display, and the contractor looks at the contents of the displayed report file and corrects the construction contents in accordance with the indications such as differences (step S17).

  By the way, in the process shown in FIG.2, FIG.4, FIG.5, although it started by accessing the server 1 using the terminal 3 from the builder side, in order to cope with the case where a builder does not transmit In addition, in the present embodiment, the server 1 is provided with the cam-up means 124, and the cam-up means 124 notifies the builder of the transmission delay of the construction data and construction time data.

  That is, the processing in the server 1 does not start unless construction data and construction time point data are transmitted with a sense of purpose of model data having a three-dimensional shape to be compared with imaging data. Therefore, as shown in FIG. 6, the cam-up means 124 provided in the arithmetic processing unit 12 is activated at a constant cycle (step S1), and by this activation, the arithmetic processing unit 12 stores the stored data in the storage unit 11 with each construction work number. Search is performed (step S2), and construction time data and construction specification data for each construction work number are selected (step S3). The product number of the construction target is extracted from the selected construction specification data (step S4), and the standard process table stored in the storage unit 10 is searched with the extracted product product number (step S5). Then, the standard process chart that matches the product number is selected (step S6). On the other hand, the construction process number and the latest update date and time during work are extracted from the construction time point data selected from the storage unit 11 (step S7), and the standard work man-hour corresponding to the construction process corresponding to the extracted construction process number during work is calculated. Extraction is performed from the standard process chart selected in step S6 (step S8). The cam-up means 124 calculates the difference between the current date and time and the update date and time extracted in step S7, and compares this calculated value with the standard man-hour extracted in step S8 (step S9). When the display work man-hour is smaller than the calculated value by this comparison, the basic construction data of the storage unit 11 is searched (step S10), and the contact information of the terminal 3 of the constructor is extracted from this search (step S11). . In addition, a message is generated that the man-hour is spent longer than the standard construction time in the construction process currently being worked on (step S12). In other words, if the original construction data or construction time data should be sent from the contractor within the standard construction time, but not sent, the processing of steps S11 and S12 is performed, and extracted in step S11. The message is called and transmitted to the contact information of the terminal 3 that has been made (step S13). A message is displayed at the terminal 3 that has received the message, and the contractor sees this message and knows that the transmission of the construction data and the construction time point data is delayed (step S14).

  As a result, the installer is aware that the terminal 3 will transmit these data without delay.

  In FIGS. 2 and 4 to 6 described above, the processing is related to the construction quality control until the completion of construction. However, the system according to this embodiment can provide after-sales service after the construction is completed. ing.

  In other words, after the construction is completed, the service life of the housing equipment is managed, and when this service life expires, the service that automatically performs the maintenance necessary for the contractor and the reception of repair requests from the owner side In addition, it is possible to provide services such as processing of communication of the reception request and the construction request for repair to the contractor and repair service for the contractor.

  These services are described below.

  First, the former service performs the following processing. The cam-up means 124 provided in the arithmetic processing unit 12 is activated at a constant period corresponding to the maintenance process as in step S1 in FIG. By this activation, the arithmetic processing unit 12 searches for a construction work number in which the construction completion flag is set in the stored data of the storage unit 11. Here, the construction completion flag is set in advance for each construction work number for which construction has been completed. And the construction time data and construction specification data of each construction work number for which the construction completion flag is set by the search are selected, and the product number of the construction target is extracted from this selected construction specification data in the same manner as in step S4 of FIG. The design data in the storage unit 10 is searched with the extracted product item number. In this search, design data matching the product number is selected. On the other hand, the construction completion date and time is extracted from the construction time point data selected from the storage unit 11. It is assumed that the date and time is written in each construction time point data when construction is completed. The arithmetic processing unit 12 that has extracted the construction completion date and time extracts the length of the useful life of the target component from the design data selected as described above. In the design data, it is assumed that the length of the useful life of each part of the household equipment is written in advance as data.

  Then, the cam-up means 124 calculates the difference between the current date and time and the construction completion date and compares this calculated value with the length of the extracted useful life of each component. Is longer than the calculated value, the installer basic data stored in the storage unit 11 is searched, and the contact information of the installer's terminal 3 is extracted from this search. Also, a message is created to the builder that the △ part of the house equipment in the house that has been constructed in the past has expired. Then, the message is called and transmitted to the contact information of the terminal 3 extracted as described above. The terminal 3 that has received this message displays a message, and the contractor sees this message and notifies the owner of the residence that maintenance is necessary.

  After the above process, the contractor will know that the lifetime of the component parts of the house equipment previously constructed has passed and will inform the client that it is necessary to take appropriate measures. Can be planned.

  On the other hand, the latter service corresponds to the case where the housing equipment has failed on the owner side, and the processing in this service will be described below with reference to FIG.

  First, the server 1 generates additional data consisting of image data taken from the terminal 3 'owned by the owner, and the text data describing the failure situation and user contact information. Call / send (step S1). When the server 1 receives failure data from the terminal 3 'through the communication unit 13 (step S2), the arithmetic processing unit 12 takes in the failure data and analyzes the failure data (step S3). By this analysis, the contact information of the owner is extracted from the additional data (step S4), and the stored data in the storage unit 11 is searched with the extracted contact information (step S5). By this search, owner basic data, construction specification data, construction point-in-time data, and contractor basic data that match the contact information of the owner are selected (step S6). The product number of the construction object is extracted from the selected construction specification data (step S7), the design data in the storage unit 11 is searched with the extracted product number (step S8), and the design data that matches the product number A standard process chart is selected (step S9). On the other hand, the component specification data to be constructed is extracted from the selected construction specification data (step S10), and the model data of the component corresponding to this component specification is extracted from the design data selected in step S9 (step S11). ). Then, an assembly model having a three-dimensional shape in an assembly state is constructed using only the components having the construction specifications (step S12), and the image data generation means 120 is composed of virtual computer graphics obtained by viewing this assembly model from various angles. A plurality of still image data is generated (step S13). Next, the shooting position detection unit 121 of the arithmetic processing unit 12 arranges specific parts of the generated plurality of still image data, and the angle view (line direction) of the image indicated by the shooting data from the view, that is, the shooting position and the shooting. The direction is detected, still image data viewed from the same position and direction as the detected photographing position and photographing direction is selected (step S14), and the construction state analyzing means 122 further selects the selected still image data and the photographing data. Are compared using a known pattern recognition method to identify a failed component (step S15). Then, the unit price of the failed part, the length of the standard acquisition period, and the installation man-hour are extracted from the design data (step S16). Based on the extracted data, the report output unit 124 repairs the part replacement and the period required for the repair. Is output to a report file (step S17). Then, the report file is called and transmitted through the communication unit 13 to the client terminal 3 'that has sent the failure data (step S18).

  Upon receiving the report file, the owner's terminal 3 'displays the contents of the report file and indicates to the owner the cost and period required for repair (step S19). The client examines the repair by looking at the contents of the report file, and when repairing, the client returns a repair request to the server 1 using the terminal 3 ′. When the report output means 124 of the arithmetic processing unit 12 of the server 1 receives the reply of the repair request through the communication unit 13, the contact information of the contractor is obtained from the basic data of the contractor selected in step S6 from the stored data of the storage unit 11.
