[0018] As another example of the present invention, in the construction site information output system, the management node and the communication nodes form a network via a predetermined blockchain.

Advantages of the Invention

[0019] According to the construction site information output system of the present invention, the management node stores the construction site images of each construction site and the images of each work location at each construction site transmitted from those web cameras separately for each construction site and each work location, and stores the work processes performed by each construction-related person at the work locations of a predetermined construction site separately for each work location and each construction-related person. The management node transmits the construction site image of the predetermined construction site where the construction-related person works and the image of the predetermined work location at that construction site among the stored work location images at each construction site to the communication node of the construction-related person, and transmits the work process corresponding to the work performed by the predetermined construction-related person among the stored work processes at each work location to the communication node of the construction-related person. The communication node receives the construction site image of the predetermined construction site where the construction-related person works and the image of the predetermined work location at that construction site transmitted from the management node, outputs the received construction site image of the predetermined construction site and the image of the predetermined work location at that construction site, receives the work process of the work performed by the construction-related person transmitted from the management node, and outputs the received work process. Therefore, each construction-related person who works or plans to work at each work location of each construction site can be notified by the management node of the construction site image of that construction site, the image of the work location at the work location of that construction site, and the work process at that work location. By outputting the construction site image, the image of the work location at the work location of the construction site, and the work process at the work location by the communication node, the construction-related person can be allowed to view the construction site image and the work location image of each construction site where they work or plan to work, and can know the work process at each work location of the predetermined construction site.

[0020] The construction site information output system, where the management node classifies and stores the work process images performed by each construction-related person at the work locations of a predetermined construction site for each work location and each construction-related person, transmits the work process images corresponding to the work performed by a predetermined construction-related person among the stored work process images at each work location to the communication node of the construction-related person, the communication node receives the work process images of the work performed by the construction-related person transmitted from the management node, and outputs the received work process images, enables each construction-related person to visually confirm the work process at the work locations of the construction site by the communication node outputting the work process images of the work performed by the construction-related person transmitted from the management node, enables each construction-related person to specifically grasp the work process at the work locations of the construction site, and enables the work at the work locations of the construction site to be efficiently carried out.

[0021] The construction site information output system, where the management node classifies and stores various education images at each construction site for each construction site and each work location, transmits the education image of a predetermined work location at a predetermined construction site among the education images at each work location of each stored construction site to the communication node of the construction-related person working at the predetermined work location at the predetermined construction site, the communication node receives the education image transmitted from the management node, and outputs the received education image, enables the communication node to output the education images at each work location of each construction site transmitted from the management node, so that various education images at each work location of each construction site can be shown to each construction-related person via the communication node, enables each education related to the construction work to be carried out at each work location of each construction site, and can improve the accuracy and efficiency of the work at the work locations of the construction site.

[0022] The management node classifies and stores the contact items for each construction-related person at each construction site for each construction site and each work location, and transmits the contact items for a specified work location at a specified construction site among the contact items for each work location at each construction site it has stored to the communication node of the construction-related person working at the specified work location at the specified construction site. The construction site information output system that receives the contact items transmitted from the management node by the communication node and outputs the received contact items can notify each construction-related person of various contact items at each work location at each construction site via the communication node by outputting the contact items for each work location at each construction site transmitted from the management node by the communication node, enabling smooth and accurate communication at each work location at each construction site and achieving thorough dissemination of contact items at each construction site.

[0023] The management node creates a construction work progress image in which the work location images of each work location at each construction site from the past to the present are arranged in chronological order from the past to the present, stores the created construction work progress image in a state classified for each construction site and each work location, and transmits the construction work progress image of a specified work location at a specified construction site among the construction work progress images of each work location at each construction site it has stored to the communication node of the construction-related person working at the specified work location at the specified construction site. The construction site information output system that receives the construction work progress image of a specified work location at a specified construction site transmitted from the management node by the communication node and outputs the received construction work progress image can enable each construction-related person to know the progress of the construction work at the work location of that construction site by outputting the construction work progress image of a specified work location at a specified construction site transmitted from the management node by the communication node, enabling the specific progress of the construction work to be grasped and the pace of the construction work to be adjusted to proceed with the construction work on schedule.

[0024] The management node creates a work progress schedule comparison image in which the work progress schedule images from before work to the completion of work at each work location at each construction site are arranged in chronological order, stores the created work progress schedule comparison image in a state divided by each construction site and each work location, compares the current work location image of a predetermined work location at a predetermined construction site transmitted from a web camera with the work progress schedule comparison image of the predetermined work location at the predetermined construction site stored, determines whether the construction work progress status based on the current work location image transmitted from the web camera lags behind the construction work progress schedule based on the work progress schedule comparison image, and if it is determined that the construction work is delayed, transmits work delay information to the communication node of the construction-related person working at the work location of the construction site where the construction work is delayed. The construction site information output system that receives the work delay information of the work location of a predetermined construction site transmitted from the management node by the communication node and outputs the received work delay information can, when the current construction work progress status lags behind the construction work progress schedule, output the work delay information of the predetermined work location of the predetermined construction site transmitted from the management node by the communication node. Therefore, each construction-related person can know the delay of the construction work at the work location of the construction site, and by accelerating the pace of the construction work at the work location, each construction-related person can advance the construction work on schedule.

[0025] It includes an access management node that is installed at each construction site to form a management node and a network, and manages the entry and exit of construction-related personnel working at a predetermined construction site. The management node stores the face images of each construction-related personnel separately for each construction-related personnel and each construction site where each construction-related personnel works. When a construction-related personnel inputs entry information to the access management node installed at the construction site where he / she works and transmits a comparison face image of himself / herself at the time of entry using a communication node, it compares the stored face image of the construction-related personnel with the comparison face image transmitted from the communication node. As a result of comparing the face image of the construction-related personnel with the comparison face image, if the comparison face image matches the face image of the construction-related personnel, it certifies the entry of the construction-related personnel possessing the communication node that transmitted the comparison face image into the construction site, totals the number of entries of the construction-related personnel whose entry has been certified for each construction site separately, and outputs the totaled number of entries in a state where it is separated for each construction site. The construction site information output system can prevent the entry of unrelated third parties into the construction site by performing face authentication to identify legitimate construction-related personnel and allowing the identified construction-related personnel to enter the construction site, can allow only legitimate construction-related personnel to enter the construction site, and can prevent the occurrence of accidents and crimes at the construction site. Since the construction site information output system totals the number of entrants of the construction-related personnel whose entry has been certified by the management node for each construction site and outputs the totaled number of entrants for each construction site, the number of entrants for each construction site of the construction-related personnel such as managers and on-site supervisors among the construction-related personnel whose entry has been certified can be known, and the number of entrants for each construction site of the construction-related personnel whose entry has been certified by managers and on-site supervisors can be accurately grasped.

[0026] When the management node inputs the departure information to the entry / exit management node installed at the construction site where the construction worker has worked, and transmits the comparison face image of the construction worker himself / herself at the time of departure using the communication node, the stored face image of the construction worker is compared with the comparison face image transmitted from the communication node. As a result of comparing the face image of the construction worker with the comparison face image, if the comparison face image matches the face image of the construction worker, the departure of the construction worker who possesses the communication node that transmitted the comparison face image from the construction site is certified. At the same time, the number of departures of the construction workers whose departures have been certified is classified and aggregated for each construction site, and the aggregated number of departures is output in a state where it is classified for each construction site. The construction site information output system can identify legitimate construction workers through face authentication and allow only legitimate construction workers to enter the construction site and then leave the construction site, thereby preventing accidents and crimes from occurring at the construction site. Since the construction site information output system aggregates the number of departing construction workers whose departures have been certified by the management node for each construction site and outputs the aggregated number of departing construction workers for each construction site, managers, site supervisors, etc. among the construction workers can know the number of departing construction workers for each construction site where the departure has been certified, and managers, site supervisors, etc. can accurately grasp the number of departing construction workers whose departures have been certified for each construction site.

[0027] The construction site information output system that can display a plurality of gadgets in the management node and the communication node and can change existing gadgets to other gadgets in the management node and the communication node can open a plurality of various sites using the plurality of various gadgets output to the management node and the communication node, and construction workers can use these sites to purchase items, conduct various searches, various investigations, etc. Since the construction site information output system can change existing gadgets to other gadgets in the management node and the communication node, it is possible to select gadgets that are useful for construction workers and open sites necessary for construction work.

[0028] A construction site information output system capable of outputting a plurality of information display blocks on one screen of a management node and a communication node, and at least two of an image of a work location at a construction site, a work process at the work location, an image of the work process at the work location, an education image at the construction site, contact information at the construction site, an image of the progress of construction work at the work location, and work delay information at the work location are separately output to each information display block output on one screen. By outputting various information and images to the plurality of information display blocks output on one screen, construction-related personnel can view a plurality of information on one screen and can know a plurality of information at once on one screen.

[0029] In a construction site information output system in which a management node and those communication nodes form a network via a predetermined blockchain, the management node and those communication nodes form a network via the blockchain, and an image of a work location at the construction site, a work process at the work location, an image of the work process at the work location, an education image at the construction site, contact information at the construction site, an image of the progress of construction work at the work location, and work delay information at the work location are stored in the management node as transaction data. Therefore, while preventing the falsification of the image of the work location at the construction site, the work process at the work location, the image of the work process at the work location, the education image at the construction site, the contact information at the construction site, the image of the progress of construction work at the work location, and the work delay information at the work location, an accurate history of the image of the work location at the construction site, the work process at the work location, the image of the work process at the work location, the education image at the construction site, the contact information at the construction site, the image of the progress of construction work at the work location, and the work delay information at the work location can be saved.

The educational images are stored in the large-capacity virtual memory area (large-capacity storage area (or large-capacity hard disk)) of the management server 14 in a state divided for each construction site and each work location. The educational images are created in advance by a management company that manages the construction site, an ordering company that has received the construction order, a subcontracting company that has undertaken the construction, etc., or are created by those companies at any time.

[0073] In the large-capacity virtual memory area (large-capacity storage area (or large-capacity hard disk)) of the management server 14, matters to be communicated (notices) to each construction-related person at each construction site (including each planned construction site) are stored (held) in a state associated with a construction site identification number (construction site identifier) that identifies construction sites 16a to 16c and planned construction sites 16a to 16c, and a work location identification number (work location identifier) that identifies work locations and planned work locations (communication matter storage means). The communication matters are stored in the large-capacity virtual memory area (large-capacity storage area (or large-capacity hard disk)) of the management server 14 in a state classified for each construction site and each work location. The communication matters are created in advance by a management company that manages the construction site, an order-receiving company that received the construction order, a subcontracting company that undertakes the construction, etc., or are created by those companies at any time.

[0074] Those web cameras 15 are installed at predetermined positions on each work location (each work floor) of each floor at each construction site 16a to 16c. Those web cameras 15 take images of the work locations on each floor of each construction site 16a to 16c in time series (continuously, at intervals of one day, one week, ten days, one month, etc.), and transmit the captured work location images to the first to third personal computers 13a to 13b. Incidentally, the shooting interval of the web camera 15 can be arbitrarily set and changed.

[0079] After the construction-related person who has confirmed the construction-related person identification number, name, and face image inputs the name of the first construction site 16a where he / she works or the first construction site 16a where he / she plans to work in the construction site input area of the construction site selection area, or selects the name of the first construction site 16a where he / she works or plans to work from the construction site name pull-down list, the construction site determination button is tapped. When the construction site determination button is tapped, the central processing unit of the tablet 11a uses the URL of the management server 14 to access and log in to the management server 14 via the Internet, and transmits the construction site specific information (construction site specific identifier) corresponding to the construction site name and construction site address input in the construction site input area, or the construction site specific information (construction site specific identifier) corresponding to the construction site name selected from the construction site name pull-down list, together with a construction site image transmission request signal and communication node specific information (communication node specific identifier) to the management server 14.

[0080] The management server 14 that has received the construction site specific information, communication node specific information, and construction site image transmission request signal from the tablet 11a extracts the construction site information corresponding to the construction site specific information and the construction site image of the construction site 16a from a large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)), and transmits the extracted construction site information and construction site image of the first construction site 16a to the tablet 11a via the Internet (construction site work location image transmission means). The central processing unit of the tablet 11a receives the construction site information and construction site image of the first construction site 16a transmitted from the management server 14 by the construction site work location image transmission means (construction site work location image receiving means).

[0081] The central processing unit of the tablet 11a that has received the construction site information and construction site image of the first construction site 16a from the management server 14 outputs (displays) the construction site image output screen 20 shown in FIG. 4 on the touch panel 17 (construction site work location image output means). On the construction site image output screen 20 shown in FIG. 4, there are a construction site information output area 20a that outputs (displays) construction site information (name of the construction site, address of the construction site, telephone number and email address of the construction site, construction period of the construction site, name of the person in charge of the construction site, etc.), a construction site image output area 20b that outputs (displays) the construction site image, a position information output area 20c that outputs (displays) the position information of the construction site, a work location image output button 20d, a menu screen button 20e, and an end button 20f are output (displayed). In the position information output area 20c, the position of a predetermined first construction site 16a (or planned construction site 16a) where construction-related personnel work is output (displayed) on the map. When the menu screen button 20e is tapped, the multi-window menu screen 19 in FIG. 3 is output (displayed) on the touch panel 17 (the same applies to the following menu screen buttons).

[0082] To view the image of the working area of the construction site 16a output (displayed) on the construction site image output screen surface 20 of FIG. 4, tap the working area image information window 19b of the multi-window menu screen 19 or the working area image output button 20d of the construction site image output screen surface 20. When the working area image information window 19b or the working area image output button 21d is tapped, a working area designation screen (not shown) is output (displayed) on the touch panel 17 of the tablet 11a. The working area designation screen outputs (displays) a construction site information output area that outputs (displays) construction site information (name of the construction site, address of the construction site), an internal three-dimensional image output area that outputs (displays) an internal three-dimensional image of the first construction site 16a, a working area name pull-down list that outputs (displays) the names of each working area of the first construction site 16a, a working area determination button, a menu screen button, and an end button.

[0083] When the cursor is positioned at a predetermined internal three-dimensional image position in the internal three-dimensional image of the internal three-dimensional image output area and double-clicked, the central processing unit of the tablet 11a transmits the working area specific information (working area specific identifier) indicated by the internal three-dimensional image where the cursor is positioned, together with the construction site specific information (construction site specific identifier) and the working area image transmission request signal, to the management server 14 as communication node specific information (communication node specific identifier). Alternatively, after selecting (inverting) (multiple selections possible) a predetermined working area name from the working area names output (displayed) in the working area name pull-down list and then tapping the working area determination button, the central processing unit of the tablet 11a transmits the working area specific information (working area specific identifier) selected in the working area name pull-down list, together with the construction site specific information (construction site specific identifier) and the working area image transmission request signal, to the management server 14 as communication node specific information (communication node specific identifier).

[0084] The management server 14 that has received the work location specific information, construction site specific information, communication node specific information, and work location image transmission request signal from the tablet 11a extracts a work location image corresponding to the work location specific information of the construction site corresponding to the construction site specific information from a large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)), and transmits the extracted construction site information and work location image of the construction site 16a to the tablet 11a via the Internet (construction site work location image transmission means). The central processing unit of the tablet 11a receives the construction site information and work location image of the construction site 16a transmitted from the management server 14 by the construction site work location image transmission means (construction site work location image reception means).

[0085] The central processing unit of the tablet 11a that has received the construction site information and work location image of the construction site 16a from the management server 14 outputs (displays) the work location image output screen 21 shown in FIG. 5 on the touch panel 17 (construction site work location image output means). On the work location image output screen 21 shown in FIG. 5, a construction site information output area 21a that outputs (displays) construction site information (name of the construction site, address of the construction site, name of the work location of the work location), a work location image output area 21b that outputs (displays) the work location image, a work process output button 21c, a work process image output button 21d, a menu screen button 21e, and an end button 21f are output (displayed).

[0086] The construction site information output system 10 is configured such that the management server 14 (management node) classifies and stores the construction site images of each construction site and the images of each work location at each construction site transmitted from those web cameras 15 for each construction site and each work location. Among the images of the work locations at each construction site that are stored, the management server 14 transmits the construction site image of the first construction site 16a (predetermined construction site) where construction-related personnel work and the image of the predetermined work location at the first construction site 16a to the tablet 11a (communication node) of the construction-related personnel. The tablet 11a receives the construction site image of the first construction site 16a (predetermined construction site) where construction-related personnel work and the image of the predetermined work location at the first construction site 16a transmitted from the management node, and outputs the received construction site image of the first construction site 16a (predetermined construction site) and the image of the predetermined work location at the first construction site 16a. Therefore, it is possible to notify the construction-related personnel working or planning to work at each work location of the first construction site 16a (each construction site) of the construction site image of the first construction site 16a and the image of the work location at the work location of the first construction site 16a from the management server 14. By the tablet 11a outputting the construction site image of the first construction site 16a (predetermined construction site) and the image of the work location at the work location of the first construction site 16a, the construction-related personnel can view the construction site image and the work location image of the first construction site 16a (each construction site) where they work or have a work plan.

[0087] FIG. 6 is a diagram showing an example of a work process output screen 22 output (displayed) on the touch panel 17 of the tablet 11a. In FIG. 6, the display of each data output to each output area is omitted. To view the work process at each work location of the first work site 16a, tap the work process information window 19c on the multi-window menu screen 19.

[0088] When the work process information window 19c is tapped, the central processing unit of the tablet 11a transmits, via the Internet, the construction worker identification number (construction worker identification identifier) of the construction worker who owns the tablet 11a and the work process transmission request signal, together with communication node identification information (communication node identification identifier), to the management server 14. The central processing unit of the management server 14 that has received the construction worker identification number (construction worker identification identifier), the work process transmission request signal, and the communication node identification information (communication node identification identifier) from the tablet 11a extracts the construction worker identification information (construction worker identifier) corresponding to the communication node identification information (communication node identification identifier) stored by the construction worker information storage means. When the extracted construction worker identification information (construction worker identifier) matches the transmitted construction worker identification information (construction worker identification identifier), the management server 14 extracts the construction site identification information (construction site identification identifier) and the work location identification information (work location identification identifier) corresponding to the construction worker identification number (construction worker identification identifier) stored by the construction site work location storage means.

[0089] Next, the central processing unit of the management server 14 extracts the construction site information of the first construction site 16a corresponding to the construction site identification information (construction site identification identifier) from the construction site information stored by the construction site information storage means, extracts the work location and the planned work location of the first construction site 16a corresponding to the work location identification information (work location identification identifier) from the construction site information, and extracts the period during which the construction worker identified by the construction worker identification number (construction worker identification identifier) works at the work location and the planned work location in the first construction site 16a and each work day. Further, the central processing unit of the management server 14 outputs (displays) a work day designation screen (not shown) for the work day on which the work process is output (displayed) to the touch panel of the tablet 11a.

[0090] On the work date designation screen of the work process output (display) output (displayed) on the touch panel of the tablet 11a, there are a construction site information output area that outputs (displays) construction site information (name of the construction site, address of the construction site), a work date input area for the work date on which the work process is output (displayed), a work date pull-down list for the work date on which the construction-related person specified by the construction-related person identification number (construction-related person identifier) works, an internal three-dimensional image output area that outputs (displays) an internal three-dimensional image of the building at the construction site where the construction-related person works, a work date selection button, a menu screen button, and an end button that are output (displayed).

[0091] The construction-related person inputs (multiple inputs are possible) the work date on which the work process is output (displayed) in the work date input area, or selects (inverts) (multiple selections are possible) the work date on which the work process is output (displayed) from the work date pull-down list, and then taps the work date selection button. Alternatively, after inputting the work date on which the work process is output (displayed) in the work date input area, or selecting (inverting) the work date on which the work process is output (displayed) from the work date pull-down list, the cursor is positioned at a predetermined internal three-dimensional image position of the internal three-dimensional image in the internal three-dimensional image output area and double-clicked.

[0092] When the work date selection button is tapped, the central processing unit of the tablet 11a transmits the work date input in the work date input area or the work date selected in the work date pull-down list to the management server 14. Also, when the cursor is positioned at a predetermined internal three-dimensional image position of the internal three-dimensional image in the internal three-dimensional image output area and double-clicked, the central processing unit of the tablet 11a transmits the work date input in the work date input area or the work date selected in the work date pull-down list to the management server 14, and also transmits the work location identification information (work location identifier) indicated by the internal three-dimensional image where the cursor is positioned to the management server 14.

[0093] The central processing unit of the management server 14 extracts, from the work processes stored by the work process storage means, the work process corresponding to the work date received from the tablet 11a, or extracts the work process of the work location corresponding to the work location specific information of the construction site corresponding to the construction site specific information from the large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)), and transmits the work process of the work date at the work location of the construction site 16a thus extracted to the tablet 11a via the Internet (work process transmission means). The central processing unit of the tablet 11a receives the work process of the work date at the work location of the construction site 16a transmitted from the management server 14 by the work process transmission means (work process reception means).

[0094] The central processing unit of the tablet 11a that has received the work process of the work location of the construction site 16a from the management server 14 outputs (displays) the work process output screen 22 shown in FIG. 6 on the touch panel 17 (work process output means). On the work process output screen 22 shown in FIG. 6, there are output (displayed) a construction site information output area 22a that outputs (displays) construction site information (name of the construction site, address of the construction site, name of the work location of the work location), a work location image output area 22b that outputs (displays) a work location image, a designated work date output area 22c that outputs (displays) the designated work date, a work process output area 22d that outputs (displays) the work process of the work location of the work location image, a work process image output button 22e, a menu screen button 22f, and an end button 22g. The person concerned in the construction-related matters can confirm the work process of the predetermined work location on the designated work date by viewing the work date output in the designated work date output area 22c and the work process image output in the work process output area 22d of the work process output screen 22 in FIG. 6.

[0095] The central processing unit of the tablet 11a that has received the construction work progress image of a predetermined workday (at least one workday) at the work location of the construction site 16a from the management server 14 outputs (displays) the construction work progress image output screen 25 shown in FIG. 8 on the touch panel 17 (construction work progress image output means). On the construction work progress image output screen 24 shown in FIG. 8, there are a construction site information output area 24a that outputs (displays) construction site information (name of the construction site, address of the construction site), a work location image output area 24b that outputs (displays) the work location image, a designated workday output area 24c that outputs (displays) the designated workday, a construction work progress image output area 24d that outputs (displays) the construction work progress image of the work location of the work location image, a menu screen button 24e, and an end button 24f that are output (displayed). By looking at the workday output in the designated workday output area 24c of the construction work progress image output screen 24 in FIG. 8 and the construction work progress image output in the construction work progress image output area 24d, the construction-related person can confirm the progress of the construction work on the designated workday.

[0096] In addition, by tapping the work process output button 21c output (displayed) on the work location image output screen 21 in FIG. 5, the work process output button 23d output (displayed) on the work process image output screen 23 in FIG. 7 to be described later, and the work process output button 25e output (displayed) on the work delay information output screen 25 in FIG. 9, the work process of the work location of the construction site 16a designated by the work location image output screen 21 in FIG. 5, the work process image output screen 23 in FIG. 7, and the work delay information output screen 25 in FIG. 9 can be output (displayed). By tapping the work process output button 21c on the work location image output screen 21 in FIG. 5, the work process output button 23d on the work process image output screen 23 in FIG. 7, and the work process output button 25e in FIG. 9 and implementing the above-described procedure, the work process of the work location of the construction site 16a is transmitted from the management server 14 to the tablet 11a, and the central processing unit of the tablet 11a outputs (displays) the work process output screen 22 in FIG. 6 on the touch panel 17 (work process output means).

[0097] The construction site information output system 10 stores, for each work location and each construction-related person, the work processes that each construction-related person performs on a workday at the work locations of the first construction site 16a (a predetermined construction site). The system then transmits to the tablet 11a (communication node) of the construction-related person the work process corresponding to the work on the workday performed by a predetermined construction-related person among the work processes stored for each work location. The tablet 11a receives the work process of the work performed by the construction-related person transmitted from the management server 14 and outputs the received work process. Therefore, for each construction-related person working or planning to work at each work location of the first work site 16a (each construction site), the work process on the workday at that work location can be notified to the construction-related person from the management server 14. By the tablet 11a outputting the work process at the work locations of the first construction site 16a, the construction-related person can know the work process on the workday at the work locations of the first work site 16a (each construction site) where they are working or have work planned.

[0098] FIG. 7 is a diagram showing an example of a work process image output screen 23 output (displayed) on the touch panel 17 of the tablet 11a. In FIG. 7, the display of each data output to each output area is omitted. To view the work process image of the work process at each work location of the first work site 16a, tap the work process image information window 19d on the multi-window menu screen 19.

[0099] When the operation process image information window 19d is tapped, the central processing unit of the tablet 11a transmits, via the Internet, the construction-related person identification number (construction-related person identifier) of the construction-related person who holds the tablet 11a and the operation process image transmission request signal, together with communication node identification information (communication node identifier), to the management server 14. The central processing unit of the management server 14 that has received the construction-related person identification number (construction-related person identifier), the operation process image transmission request signal, and the communication node identification information (communication node identifier) from the tablet 11a extracts the construction-related person identification information (construction-related person identifier) corresponding to the communication node identification information (communication node identifier) stored by the construction-related person information storage means. When the extracted construction-related person identification information (construction-related person identifier) matches the transmitted construction-related person identification information (construction-related person identifier), the central processing unit of the management server 14 extracts the construction site identification information (construction site identifier) and the work location identification information (work location identifier) corresponding to the construction-related person identification number (construction-related person identifier) stored by the construction site work location storage means.

[0100] Next, the central processing unit of the management server 14 extracts the construction site information of the first construction site 16a corresponding to the construction site identification information (construction site identifier) from the construction site information stored by the construction site information storage means, extracts the work location and the planned work location of the first construction site 16a corresponding to the work location identification information (work location identifier) from the construction site information, and extracts the period during which the construction-related person specified by the construction-related person identification number (construction-related person identifier) works at the work location and the planned work location at the first construction site 16a and each work day. Further, the central processing unit of the management server 14 outputs (displays) a work day designation screen (not shown) for the work day on which the operation process image is output (displayed) to the touch panel 17 of the tablet 11a.

[0101] On the work date designation screen for the work process image output (display) output (displayed) on the touch panel 17 of the tablet 11a, there are a construction site information output area that outputs (displays) construction site information (name of the construction site, address of the construction site), a work date input area for the work date on which the work process image is output (displayed), a work date pull-down list for the work date on which the construction-related person identified by the construction-related person identification number (construction-related person identifier) works, an internal three-dimensional image output area that outputs (displays) an internal three-dimensional image of the building at the construction site where the construction-related person works, a work date selection button, a menu screen button, and an end button that are output (displayed).

[0102] The construction-related person inputs (multiple inputs are possible) the work date on which the work process image is output (displayed) in the work date input area, or selects (inverts) (multiple selections are possible) the work date on which the work process image is output (displayed) from the work date pull-down list, and then taps the work date selection button. Alternatively, after inputting the work date on which the work process image is output (displayed) in the work date input area or selecting (inverting) the work date on which the work process image is output (displayed) from the work date pull-down list, the cursor is positioned at a predetermined internal three-dimensional image position in the internal three-dimensional image of the internal three-dimensional image output area and double-clicked.

[0103] When the work date selection button is tapped, the central processing unit of the tablet 11a transmits the work date input in the work date input area or the work date selected in the work date pull-down list to the management server 14. Also, when the cursor is positioned at a predetermined internal three-dimensional image position in the internal three-dimensional image of the internal three-dimensional image output area and double-clicked, the central processing unit of the tablet 11a transmits the work date input in the work date input area or the work date selected in the work date pull-down list to the management server 14, and also transmits the work location identification information (work location identifier) indicated by the internal three-dimensional image where the cursor is positioned to the management server 14.

[0104] The central processing unit of the management server 14 extracts, from the work process images stored by the work process image storage means, the work process image corresponding to the work date received from the tablet 11a, or extracts the work process image of the work location corresponding to the work location specific information of the construction site corresponding to the construction site specific information from the large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)), and transmits the work process image of the work date at the work location of the construction site 16a thus extracted to the tablet 11a via the Internet (work process image transmission means). The central processing unit of the tablet 11a receives the work process image of the work date at the work location of the construction site 16a transmitted from the management server 14 by the work process image transmission means (work process image reception means).

[0105] The central processing unit of the tablet 11a that has received the work process images of the work processes performed by each construction-related person on the work date at the work location of the construction site 16a from the management server 14 outputs (displays) the work process image output screen 23 shown in FIG. 7 on the touch panel 17 (work process image output means). On the work process image output screen 23 shown in FIG. 7, there are output (displayed) a construction site information output area 23a that outputs (displays) construction site information (name of the construction site, address of the construction site, name of the work location of the work location), a work location image output area 23b that outputs (displays) the work location image, a designated work date output area 23c that outputs (displays) the designated work date, a work process image output area 23d that outputs (displays) the work process image (video) of the work location of the work location image, a work process output button 23e, a menu screen button 23f, and an end button 23g. By viewing the work date output in the designated work date output area 23c and the work process image (video) output in the work process image output area 23d of the work process image output screen 23 in FIG. 7, the construction-related person can confirm the work process image of the predetermined work location on the designated work date.

[0106] By tapping the work process image output button 21d output (displayed) on the work location image output screen 21 in FIG. 5, the work process image output button 22d output (displayed) on the work process output screen 22 in FIG. 6, or the work process image output button 25f output (displayed) on the work delay information output screen 25 in FIG. 9, it is possible to output (display) the work process image of the work location of the first construction site 16a designated by the work location image output screen 22 in FIG. 7, the work process output screen 24 in FIG. 5, or the work delay information output screen 25 in FIG. 9. By tapping the work process image output button 21e on the work location image output screen 21 in FIG. 5, the work process image output button 22d on the work process output screen 22 in FIG. 6, or the work process image output button 25f on the work delay information output screen 25 in FIG. 9 and implementing the above-described procedure, the work process images of the work processes performed by each construction-related person on the work day at the work location of the construction site 16a are transmitted from the management server 14 to the tablet 11a, and the central processing unit of the tablet 11a outputs (displays) the work process image output screen 22 in FIG. 7 on the touch panel 17 (work process image output means).

[0107] In the construction site information output system 10, the management server 14 (management node) stores the work process images of the work processes performed by each construction-related person at the work locations of the first construction site 16a (predetermined construction site) separately for each work location and each construction-related person, and transmits the work process image of the work process corresponding to the work performed by a predetermined construction-related person on the work day among the stored work process images of the work processes at each work location to the tablet 11a (communication node) of the construction-related person. Since the tablet 11a receives the work process image of the work process performed by the construction-related person transmitted from the management server 14 and outputs the received work process image, it is possible to notify each construction-related person who works or plans to work at each work location of the first work site 16a (each construction site) of the work process image of the work process at that work location from the management server 14 to the construction-related person. By the tablet 11a outputting the work process image of the work process at the work location of the first construction site 16a, the construction-related person can know the work process image related to the work process at the work location of the first work site 16a (each construction site) where they work or have a work plan.

[0108] FIG. 8 is a diagram showing an example of a construction work progress image output screen 24 output (displayed) on the touch panel 17 of the tablet 11a. In FIG. 8, the display of each data output to each output area is omitted. To view the construction work progress image of the work at each work location of the first work site 16a, tap the construction work progress image information window 19e of the multi-window menu screen 19.

[0109] When the construction work progress image information window 19e is tapped, the central processing unit of the tablet 11a transmits the construction worker identification number (construction worker identification identifier) of the construction worker who owns the tablet 11a and the construction work progress image transmission request signal to the management server 14 via the Internet together with the communication node identification information (communication node identification identifier). The central processing unit of the management server 14 that has received the construction worker identification number (construction worker identification identifier), the construction work progress image transmission request signal, and the communication node identification information (communication node identification identifier) from the tablet 11a extracts the construction worker identification information (construction worker identifier) corresponding to the communication node identification information (communication node identification identifier) stored by the construction worker information storage means. When the extracted construction worker identification information (construction worker identifier) matches the transmitted construction worker identification information (construction worker identification identifier), the construction site identification information (construction site identification identifier) and the work location identification information (work location identification identifier) corresponding to the construction worker identification number (construction worker identification identifier) stored by the construction site work location storage means are extracted.

[0110] Next, the central processing unit of the management server 14 extracts the construction site information of the first construction site 16a corresponding to the construction site specific information (construction site specific identifier) from the construction site information stored by the construction site information storage means, and extracts the work location and the planned work location of the first construction site 16a corresponding to the work location specific information (work location specific identifier) from the construction site information. At the same time, the central processing unit of the management server 14 extracts the period during which the construction-related person specified by the construction-related person specific number (construction-related person specific identifier) works at the work location and the planned work location in the first construction site 16a and each work day. Further, the central processing unit of the management server 14 outputs (displays) a work day designation screen (not shown) for the work day on which the construction work progress image is output (displayed) on the touch panel of the tablet 11a.

[0111] On the work day designation screen of the construction work progress image (display) output (displayed) on the touch panel of the tablet 11a, there are a construction site information output area that outputs (displays) the construction site information (name of the construction site, address of the construction site), a work day input area for the work day on which the construction work progress image is output (displayed), a work day pull-down list for the work day on which the construction-related person specified by the construction-related person specific number (construction-related person specific identifier) works, an internal three-dimensional image output area that outputs (displays) an internal three-dimensional image of the building at the construction site where the construction-related person works, a work day selection button, a menu screen button, and an end button are output (displayed).

[0112] The construction-related person inputs (multiple inputs are possible) the work day on which the construction work progress image is output (displayed) in the work day input area, or selects (inverts) (multiple selections are possible) the work day on which the construction work progress image is output (displayed) from the work day pull-down list, and then taps the work day selection button. Alternatively, after inputting the work day on which the construction work progress image is output (displayed) in the work day input area, or selecting (inverting) the work day on which the construction work progress image is output (displayed) from the work day pull-down list, the cursor is positioned at a predetermined internal three-dimensional image position in the internal three-dimensional image of the internal three-dimensional image output area and double-clicked.

[0113] When the operation date selection button is tapped, the central processing unit of the tablet 11a transmits the operation date entered in the operation date input area or the operation date selected in the operation date pull-down list to the management server 14. Also, when the cursor is positioned at a predetermined internal three-dimensional image position of the internal three-dimensional images in the internal three-dimensional image output area and double-clicked, the central processing unit of the tablet 11a transmits the operation date entered in the operation date input area or the operation date selected in the operation date pull-down list to the management server 14, and also transmits the work location identification information (work location identification identifier) indicated by the internal three-dimensional image where the cursor is positioned to the management server 14.

[0114] The central processing unit of the management server 14 extracts from the construction work progress images stored by the construction work progress image storage means the construction work progress image corresponding to the operation date received from the tablet 11a from the large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)), or extracts the construction work progress image of the work location corresponding to the work location identification information of the construction site corresponding to the construction site specific information from the large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)), and transmits the construction work progress image of the operation date at the work location of the construction site 16a thus extracted to the tablet 11a via the Internet (construction work progress image transmission means). The central processing unit of the tablet 11a receives the construction work progress image of the operation date at the work location of the construction site 16a transmitted from the management server 14 by the construction work progress image transmission means (construction work progress image reception means).

[0115] The central processing unit of the tablet 11a that has received the construction work progress image of a predetermined work day (at least one work day) at the work location of the first construction site 16a from the management server 14 outputs (displays) the construction work progress image output screen 25 shown in FIG. 8 on the touch panel 17 (construction work progress image output means). On the construction work progress image output screen 24 shown in FIG. 8, there are a construction site information output area 24a that outputs (displays) construction site information (name of the construction site, address of the construction site, name of the work location of the work location), a work location image output area 24b that outputs (displays) a work location image, a designated work day output area 24c that outputs (displays) the designated work day, a construction work progress image output area 24d that outputs (displays) the construction work progress image of the work location of the work location image, a work progress schedule comparison button 24e, a menu screen button 24f, and an end button 24g are output (displayed). By looking at the construction work progress image output in the construction work progress image output area 24d of the construction work progress image output screen 24 in FIG. 8, the construction-related personnel can confirm the progress of the construction work on the designated work day.

[0116] The construction site information output system 10 is such that the management server 14 (management node) creates a construction work progress image in which the work location images of each work location at each construction site from the past to the present are arranged in chronological order from the past to the present, stores the created construction work progress image in a state divided for each construction site and each work location, and among the construction work progress images of each work location at each construction site stored, the construction work progress image of the predetermined work location of the first construction site 16a (predetermined construction site) is transmitted to the tablet 11a (communication node) of the construction-related personnel working at the predetermined work location of the first construction site 16a (predetermined construction site). Since the tablet 11a receives the construction work progress image of the predetermined work location of the first construction site 16a (predetermined construction site) transmitted from the management server 14 and outputs the received construction work progress image, each construction-related personnel can know the progress of the construction work at the work location of the first construction site 16a, can specifically grasp the progress of the construction work, and can adjust the pace of the construction work to proceed with the construction work on schedule.

[0117] FIG. 9 is a diagram showing an example of a work delay information output screen 25 output (displayed) on the touch panel 17 of the tablet 11a. In FIG. 9, the display of each data output to each output area is omitted. To view the work delay information at each work location in the first work site 16a, tap the work delay information window 19f on the multi-window menu screen 19.

[0118] When the work delay information window 19f is tapped, the central processing unit of the tablet 11a transmits the construction worker identification number (construction worker identification identifier) of the construction worker who holds the tablet 11a and a work delay information transmission request signal to the management server 14 via the Internet together with communication node identification information (communication node identification identifier). The central processing unit of the management server 14 that has received the construction worker identification number (construction worker identification identifier), the work delay information transmission request signal, and the communication node identification information (communication node identification identifier) from the tablet 11a extracts the construction worker identification information (construction worker identifier) corresponding to the communication node identification information (communication node identification identifier) stored by the construction worker information storage means. When the extracted construction worker identification information (construction worker identifier) matches the transmitted construction worker identification information (construction worker identification identifier), the construction site identification information (construction site identification identifier) corresponding to the construction worker identification number (construction worker identification identifier) stored by the construction site work location storage means where the worker works and the work location identification information (work location identification identifier) on the date when the work delay information transmission was requested are extracted.

[0119] Next, the central processing unit of the management server 14 extracts the construction site information of the first construction site 16a corresponding to the construction site identification information (construction site identification identifier) from the construction site information stored by the construction site information storage means, and extracts the work location and work planned location of the first construction site 16a corresponding to the work location identification information (work location identification identifier) and on the date (current) when the work delay information transmission was requested from the construction site information. Further, the central processing unit of the management server 14 transmits a shooting signal of the current work location image of the work location corresponding to the work location identification information (work location identification identifier) of the first construction site 16a to the first personal computer 13a via the Internet.

[0120] The central processing unit of the first personal computer 13a that has received the shooting signal from the management server 14 transmits a shooting command signal for the current working location image of the working location to the web camera installed at the working location corresponding to the working location specific information (working location specific identifier) of the first construction site 16a. The web camera 15 that has received the shooting command signal shoots the current working location image of the working location and transmits the shot working location image to the first personal computer 13a. The central processing unit of the first personal computer 13a transmits the current working location image of the working location shot by the web camera 15 to the management server 14 together with the construction site specific information (construction site specific identifier) and the working location specific information (working location specific identifier).

[0121] The central processing unit of the management server 14 that has received the working location image of a predetermined working location of the first construction site 16a from the first personal computer 13a extracts the working progress planned comparison images of the working location and the planned working location on the date (current) when the transmission of the working delay information of the first construction site 16a was requested from among the working progress planned comparison images stored by the working progress planned comparison image storage means, and compares the extracted working progress planned comparison image with the working location image transmitted from the first personal computer 13a by performing image processing on the two images.

[0122] The central processing unit of the management server 14 determines whether the construction work progress status based on the current working location image transmitted from the first personal computer 13a (web camera 15) is behind the construction work progress plan based on the working progress planned comparison image (working delay determination means). If the central processing unit of the management server 14 determines that the construction work at the current working location is behind as a result of comparing the extracted working progress planned comparison image with the working location image transmitted from the first personal computer 13a, it transmits the working delay information to the tablet 11a of the construction-related person working at the working location of the construction site where the construction work is behind via the Internet (working delay information transmission).

[0123] Tablet 11a receives work delay information for a predetermined work location at the first construction site 16a (a predetermined construction site) transmitted from the management server 14 (work delay information receiving means). The central processing unit of tablet 11a outputs (displays) the work delay information output screen 25 shown in FIG. 9 on the touch panel 17 (work delay information output means). On the work delay information output screen 25 shown in FIG. 9, there are a construction site information output area 25a that outputs (displays) construction site information (name of the construction site, address of the construction site, name of the work location at the work location), a work location image output area 25b that outputs (displays) the current work location image, a work progress schedule comparison image output area 25c that outputs (displays) a work progress schedule comparison image for the work location, a work delay message output area 25d that outputs (displays) a work delay message, a work process output button 25e, a work process image output button 25f, a menu screen button 25g, and an end button 25h are output (displayed). The construction-related person can confirm the work delay at the work location by looking at the work delay message output in the work delay message output area 25d of the work delay information output screen 25 in FIG. 9.

[0124] In addition, by tapping the work progress schedule comparison button 24e output (displayed) on the construction work progress image output screen 24 in FIG. 8, it is possible to output (display) the work delay information for the work location at the construction site 16a specified by the work delay information output screen 25 in FIG. 9. By tapping the work progress schedule comparison button 24e on the construction work progress image output screen 24 in FIG. 8 and implementing the above-described procedure, the work delay information for the work location at the construction site 16a is transmitted from the management server 14 to the tablet 11a, and the central processing unit of the tablet 11a outputs (displays) the work delay information output screen 25 in FIG. 9 on the touch panel 17 (work delay information output means).

[0125] The construction site information output system 10 creates a work progress schedule comparison image in which the management server 14 (management node) arranges work progress schedule images from before work (the first day of work) to work completion (construction completion) at each work location at each construction site in chronological order, stores the created work progress schedule comparison image in a state divided by each construction site and each work location, and compares the current work location image of a predetermined work location at the first construction site 16a (predetermined construction site) transmitted from the web camera 15 with the work progress schedule comparison image of the predetermined work location at the first construction site 16a (predetermined construction site) stored, determines whether the construction work progress status based on the current work location image transmitted from the web camera 15 is behind the construction work progress schedule based on the work progress schedule comparison image, and if it is determined that the progress status of the current first construction site 16a is behind the construction work progress schedule, transmits work delay information to the tablet 11a (communication node) of the construction-related person working at the work location of the first construction site 16a (predetermined construction site) where the construction work is delayed. Since the tablet 11a receives the work delay information of a predetermined work location of the first construction site 16a transmitted from the management server 14 and outputs the received work delay information, each construction-related person can know the delay of the construction work at the work location of the first construction site 16a (predetermined construction site), and by aiming to speed up the construction work at the work location, the construction work can be advanced on schedule.

[0150] When the construction site information providing system 10 compares the face image of a construction-related person with a comparison face image and the comparison face image matches the face image of the construction-related person, the system authenticates the entry of the construction-related person who holds the communication node that sent the comparison face image into the first construction site 16a (construction site). By performing face authentication to identify legitimate construction-related persons and allowing the identified construction-related persons to enter the first construction site 16a, it is possible to prevent unrelated third parties from entering the first construction site 16a, allow only legitimate construction-related persons to enter the first construction site 16a, and prevent accidents and crimes from occurring at the first construction site 16a.

[0151] When a construction-related person enters the construction sites 16a to 16c where the construction-related person who holds the tablet 11a (communication node) works, the construction site information providing system 10 transmits the entry information of the construction-related person to the management server 14 (management node). Based on the entry information transmitted from the tablet 11a, the management server 14 totals the number of construction-related persons entering each of the construction sites 16a to 16c and outputs (displays) the totaled number of entry persons in a state divided for each of the construction sites 16a to 16c. Therefore, by looking at the entry person number totaling result output screens in FIGS. 12 and 13, managers, site supervisors, on-site supervisors, etc. among the construction-related persons can know the number of entry persons for each of the construction sites 16a to 16c, and managers, site supervisors, on-site supervisors, etc. can accurately grasp the number of entry persons for each of the construction sites 16a to 16c.

[0152] When a construction worker who holds the tablet 11a (communication node) enters a construction site 16a - 16c where he / she works, the construction site information providing system 10 transmits the construction worker entry information of the entering construction worker to the management server 14 (management node). The management server 14 stores the construction worker entry information transmitted from the tablet 11a for each construction site 16a - 16c, and outputs (displays) the stored construction worker entry information in a state where it is classified for each construction site 16a - 16c. Therefore, administrators, site supervisors, etc. among the construction workers can know various information of the construction workers who have entered each construction site 16a - 16c, and administrators, site supervisors, etc. can accurately grasp the construction workers who have entered each construction site 16a - 16c.

[0153] FIG. 14 is a diagram showing an example of an exit number aggregation result output screen 30 output (displayed) on the display 19 of the management server 14, and FIG. 15 is a diagram showing another example of an exit number aggregation result output screen 31 that continues from FIG. 13 and is output (displayed) on the display 19 of the management server 14.

[0154] When a construction worker exits from the first construction site 16a where the work has been completed, the worker clicks the exit button output (displayed) on the display of the first personal computer 13a installed at the construction site 16a. When the exit button is clicked, an exit screen (not shown) is output (displayed) on the display of the first personal computer 13a. The exit screen outputs (displays) a construction site information output area that outputs (displays) the construction site information of the first construction site 16a (name of the first construction site 16a, address of the first construction site 16a, telephone number and email address of the first construction site 16a, construction period of the first construction site 16a, name of the person in charge of the first construction site 16a, etc.), a construction site image output area that outputs (displays) an image of the first construction site 16a, a barcode (QR code) to be read when exiting the first construction site 16a, and a cancel button.

[0155] When a construction worker who leaves the first construction site 16a reads the barcode (QR code) output (displayed) on the display of the first personal computer 13a with the tablet 11a, a data transmission screen (not shown) that outputs (displays) a data transmission button and a cancel button is output (displayed) on the touch panel 17 of the tablet 11a. When the construction worker taps the data transmission button, an exit approval signal for the construction site 16a of the construction worker who holds the tablet 11a is transmitted from the tablet 11a to the first personal computer 13a, and the construction worker information of the construction worker who holds the tablet 11a (password, ID number, name of the construction worker, address of the construction worker, telephone number and FAX number of the construction worker, age of the construction worker, gender of the construction worker, email address, face photo of the construction worker, communication node identification information and URL of the tablet 11a held by the construction worker) is transmitted from the tablet 11a to the first personal computer 13a (exit information transmission means, construction worker exit information transmission means).

[0156] The central processing unit of the first personal computer 13a that has received the exit approval signal and the construction worker information transmits the received construction worker information to the management server 14 via the Internet (exit information transmission means, construction worker exit information transmission means). The central processing unit of the management server 14 that has received the exit approval signal and the construction worker information from the first personal computer 13a compares the construction worker information received from the first personal computer 13a with the construction worker information stored in the large-capacity virtual storage area (large-capacity storage area (or large-capacity hard disk)), and compares the construction site specific number (construction site specific identifier) of the work site where the first personal computer 13a is installed with the construction site specific number (construction site specific identifier) of the work site where the construction worker described in the construction worker information works (including the work schedule).

[0157] The central processing unit of the management server 14 transmits the face authentication screen output signal of the exit face authentication screen to the first personal computer 13a when the construction-related person information received from the first personal computer 13a matches the construction-related person information stored in the large-capacity virtual memory area (large-capacity storage area (or large-capacity hard disk)), and the construction site 16a where the first personal computer 13a is installed matches the construction site where the construction-related person works (including the work schedule). The central processing unit of the first personal computer 13a outputs (displays) the exit face authentication screen (not shown) on the display according to the face authentication screen output signal received from the management server 14. In addition, when the construction-related person information does not match, an exit screen is output (displayed) on the display of the first personal computer 13a together with a mismatch message.

The construction-related person puts their face into the face authentication frame or brings the face photo output (displayed) on the touch panel 17 of the tablet 11a close to the face authentication frame. The central processing unit of the first personal computer 13a transmits the face image (face image data) of the construction-related person reflected in the face authentication frame to the management server 14.

[0159] The central processing unit of the management server 14 compares the face image (face image data) of the construction-related person received from the first personal computer 13a with the face image (face image data) of the construction-related person stored in the large-capacity virtual memory area (large-capacity storage area (or large-capacity hard disk)). When the face image (face image data) received from the first personal computer 13a matches the face image (face image data) stored in the large-capacity virtual memory area (large-capacity storage area (or large-capacity hard disk)), it permits the exit of the construction-related person of that face image from the first construction site 16a (exit face authentication means), outputs (displays) an exit permission message on the display of the first personal computer 13a, and then outputs (displays) the exit screen again.

[0160] The central processing unit of the management server 14 stores (stores in) the construction-related person information of the construction-related persons who have been permitted to leave the site, together with a predetermined hash value, in a large-capacity storage area (or large-capacity hard disk) (block) for each construction site in a state associated with the date and time of permission to leave the site and the construction site identification information (construction site identifier) (construction-related person departure information storage means). The central processing unit of the management server 14 aggregates the number of departing persons of the construction-related persons who have been permitted to leave the site for each construction site (departing person number aggregation means), and stores (stores in) the aggregated number of departing persons of the construction-related persons aggregated by the departing person number aggregation means in a large-capacity storage area (or large-capacity hard disk) (block) for each construction site in a state associated with the aggregation date and time and the construction site identification information (construction site identifier) together with a hash function (departing person number storage means).

[0166] When the construction site information providing system 10 compares the face image of a person involved in construction with a comparison face image and determines that the comparison face image matches the face image of the person involved in construction, it certifies the departure of the person involved in construction who holds the communication node that transmitted the comparison face image from the first construction site 16a (construction site). Therefore, by performing face authentication to identify legitimate persons involved in construction and allowing only the identified persons involved in construction to leave the first construction site 16a, it is possible to prevent unrelated third parties from leaving the first construction site 16a, allow only legitimate persons involved in construction to leave the first construction site 16a, and prevent accidents and crimes from occurring at the first construction site 16a.

[0167] When a person involved in construction who holds the tablet 11a (communication node) leaves the construction sites 16a to 16c where the person works, the construction site information providing system 10 transmits the departure information of the person involved in construction to the management server 14 (management node). Based on the departure information transmitted from the tablet 11a, the management server 14 totals the number of persons leaving the construction sites for each of the construction sites 16a to 16c and outputs (displays) the totaled number of persons leaving in a state where it is divided for each of the construction sites 16a to 16c. Therefore, by looking at the departure number totaling result output screens in FIGS. 14 and 15, managers, site supervisors, on-site supervisors, etc. among the persons involved in construction can know the number of persons leaving each of the construction sites 16a to 16c, and managers, site supervisors, on-site supervisors, etc. can accurately grasp the number of persons leaving each of the construction sites 16a to 16c.
