  ADVANTAGE OF THE INVENTION According to this invention, the management of the process progress status in a construction site, the working status of a worker, etc. can be performed at low cost using an IC tag.

== Overall system configuration ==
FIG. 1 is an overall configuration diagram of a construction site management system according to an embodiment of the present invention. As shown in the figure, the construction site management system of the present embodiment includes a management server 10, an IC tag 12, and an IC tag reader 14.

  The IC tag 12 is attached to materials, tools, workers, etc. (hereinafter collectively referred to as “elements”) existing in the construction site. Further, the IC tag reader 14 is fixed inside each space 1 in the construction site or at an entrance to each space 1, and has a function of reading stored data from the IC tag 12, and is connected to the management server 10. It has a function to communicate with.

  Each IC tag 12 stores an ID for identifying an element to which the IC tag 12 is attached (hereinafter referred to as an element ID). When the element approaches the IC tag reader 14, the IC tag reader 14 The tag ID can be read. Each IC tag reader 14 is assigned an ID (space ID) for identifying the space 1 in which it is installed, and the element ID read from the IC tag 12 is transmitted to the management server 10 together with its own space ID. To do.

  FIG. 2 is a functional block diagram of the management server 10. As shown in the figure, the management server 10 includes a detection result database 20, an entrance / exit management database 22, a process rule database 24, a progress management database 26, a process plan database 28, etc., an information receiving unit 30, an entrance / exit. Each unit includes a management unit 32, a process progress management unit 34, a progress status display unit 36, a labor management unit 38, a work status display unit 40, and a safety management unit 42.

  In addition, as will be described later, the process rule database 24 records elements such as materials, tools, and workers necessary for the construction for each process performed at the construction site. Further, the process plan database 28 stores work plans such as work contents and schedules for each process performed at the construction site. The other databases 20, 22, and 26 are recorded with data in the course of processing by the management server 10, and these databases will be described in the corresponding sections.

== Entrance / exit management ==
The information receiving unit 30 receives the element ID read from the IC tag 12 by each IC tag reader 14 together with the space ID of the IC tag reader 14 from the IC tag reader 14. The entrance / exit management unit 32 accumulates and records the element ID and terminal ID received by the information receiving unit 30 in the detection result database 20 together with the reading date and time of the element ID. Then, based on the recording data of the detection result database 20, the entry / exit management database 22 is specified by specifying the entry / exit date / time of each element in each space by, for example, the following configuration (1) or (2). To record. In this embodiment, it is assumed that the reception date / time of the element ID by the information receiving unit 30 matches the reading date / time of the element ID, and the reception date / time is recorded as the reading date / time. However, the reading date / time may be transmitted from the IC tag reader 14 to the management server 10.

(1) Configuration in which all element IDs existing in the space are read by an IC tag reader installed in each space In this configuration (1), the IC tag reader 14 installed in each space periodically (for example, every minute) The element ID is read from the IC tag 12 and the element ID and the reading date / time are recorded in the detection result database 20. FIG. 3 shows an example of data recorded in the detection result database 20 in the method (1). As shown in the figure, the detection result database 20 records a space ID, a space name, a reading date and time, an element ID, and an element name. The management server 10 includes a master table that stores the correspondence between the space ID and the space name, and the correspondence between the element ID and the element name. The entrance / exit management unit 32 refers to these master tables. Then, the space name and element name are acquired. However, since the space and the element can be specified only by the space ID and the element ID, respectively, the space name and the element name may not be recorded in the detection result database 20.

  Based on the data recorded in the detection result database 20, the entrance / exit management unit 32 determines the entry date / time and exit date / time of each element, calculates the time spent in the space, and enters / exits management database 22. To record. Specifically, for each element, the time when the element ID is first read is defined as the entry date and time, and the time when the element ID is no longer read is defined as the exit date.

  FIG. 4 shows recorded data of the entrance / exit management database 22 corresponding to the data of FIG. For example, in the example of FIG. 3, since the element ID was read for the first time at 9:06 on March 30, 2004 in the tool A, as shown in FIG. 4, the entry date and time of the tool A is on March 30, 2004 at 9:06. 06. Thereafter, the element ID of the tool A is read at 9:07, but the element ID of the tool A and the element ID are not read at 9:08. Therefore, in this case, the leaving date and time of the tool A is 9:08 on March 30, 2004. In the example of FIG. 3, the latest reading time is March 30, 2004 11:37, and at this time, the element IDs of the materials A and B are both read, so the materials A and B Is determined to exist in the space, and as shown in FIG.

(2) Configuration in which element ID is read by IC tag reader installed at the entrance / exit of each space In this configuration (2), the time when each element enters the space is recorded by the IC tag reader 14 installed at the entrance / exit of each space. FIG. 5 shows an example of data recorded in the detection result database 20 in this configuration (2), and represents the same situation as FIG. 3 of the above configuration (1). As shown in the figure, the detection result database 20 records a space ID, entry / exit classification, entry / exit date (that is, element ID read time), element ID, element name, and the like. The entry / exit classification is, for example, “entrance” when the element ID of a certain element is read first, and thereafter, “exit” and “entrance” are alternately reversed every time the same element ID is read. Can be determined. Thus, the entry / exit date / time of each element recorded in the detection result database 20 is determined as the entry date / time and the exit date / time as it is according to the entry / exit classification. Note that the method of distinguishing between entry and exit is not limited to this. For example, IC tag readers 14 are installed at two locations near the inside and outside of the entrance and the movement of elements based on the time difference of reading by each IC tag reader 14 The direction may be recognized to determine whether to enter or leave. Alternatively, if one IC tag reader 14 capable of recognizing the moving direction is available, it is possible to determine whether to enter or leave by installing such an IC tag reader 14.

  FIG. 6 shows recorded data in the entrance / exit management database 22 corresponding to the data of FIG. For example, for tool A, the entry / exit date of March 30, 2004, 9:06 is “entrance”, so the admission date is March 30, 2004, 9:06, and the entry / exit date is March 2004. Since the entry / exit classification at 9:08 on the 30th is “Exit”, the exit date and time will be 9:08 on March 30, 2004.

== Process progress management ==
The process progress management unit 34 refers to the entrance / exit management database 22 and the process rule database 24 and performs process progress management. Hereinafter, the content of the process which the process progress management part 34 performs is demonstrated concretely.

FIG. 7 shows an example of data recorded in the process rule database 24. As shown in the figure, the process rule database 24 records, for each process, a process ID for identifying the process, elements necessary for construction, and necessary work time per unit construction quantity. In the example of the figure, for the process (double floor) with the process ID “101”, “Konjita”, “Particle Board”, “Double Floor Leg”, “System joist” are necessary elements for the construction. , “Double floor builder”, and “hammer” are recorded, and 0:15 hours (15 minutes) per 1 m ² is recorded as the required work time per unit construction quantity. In the case of this example, the process progress management unit 34 refers to the entrance / exit management database 22 and refers to “Kita jota”, “particle board”, “double floor leg”, “system joist”, “double floor construction”. When the “person” and the “hammer” are in the same space, it is determined that the “double floor” construction work is being performed in that space. Then, when the state continues for a required work time per unit area of 0.15 hours multiplied by the area of the space, it is determined that the work is finished.

For example, it is assumed that the data shown in FIGS. 8 and 9 are recorded in the detection result database 20 and the entrance / exit management database 22, respectively. In the detection result database 20 shown in FIG. 8, the work type is recorded in the “construction type” column for each element. This work type is obtained, for example, by providing a master table storing the correspondence between element IDs and work types for each element, and referring to this master table. In the example of FIG. 8 and FIG. 9, the necessary elements for the double floor at 9:15 on March 30, “Konjita”, “Particle board”, “Double bed leg”, “System joist”, “ Since the “double floor installer” and “hammer” are arranged in the space 502, the process progress management unit 34 determines that the configuration of the double floor has started at this point. Also, referring to the master table storing the area of each space, the area of the space 502 is acquired, and this area (for example, 10 m ² ) is multiplied by the required work time of 15 minutes per unit area of the double floor. When 150 minutes have passed, it is determined that the construction of the double floor has been completed.

  As described above, the process progress management unit 34 is based on the entry / exit date of each element in each space recorded in the entry / exit management database 22 and the elements necessary for each process recorded in the process rule database 24. , Grasp the progress of each process. Then, the progress status of each process is recorded in the progress management database 26. Note that when it is determined that the process has been completed, the administrator may be notified by e-mail or the like.

  FIG. 10 shows an example of data recorded in the progress management database 26. As shown in the figure, the progress management database 26 includes, for each space, a space ID, a process ID of each process performed in the space, progress status information indicating the progress status of the process, and the current progress status. The date when it became is recorded. The status information represents the progress status of the process by, for example, “not yet started”, “work in progress”, “work end”, “inspection end”, and the like. Among these, “inspection end” is set when the administrator inputs that the inspection has ended for the process whose progress status is “work end”.

  The process progress management unit 34 sets milestones (points for managing whether or not conditions on the process are met) on the process table as shown in FIG. 12 to be described later, and the set milestones. It also has a function of contacting the administrator by e-mail or the like when reaching the above. For example, when it is necessary to inspect the progress in about one hour after starting to construct a double floor, “one hour after the start of double floor construction” is set as a milestone, and the process progress management unit 34 When one hour elapses after the floor process is started, a screen to that effect is displayed, or a notification process such as sending an e-mail to the manager in charge of the double floor process is performed.

  The progress status display unit 36 displays the progress status of each process on the screen based on the data recorded in the progress management database 26.

  FIG. 11 shows a first example of a display screen by the progress status display unit 36. In this example, the progress status of the process designated for each space is displayed in shades of colors according to the progress status of the process at positions corresponding to each space on the drawing representing the construction site. According to such a display screen, it is possible to grasp the current progress status of the process on the entire site.

  FIG. 12 shows a second example of a display screen by the progress status display unit 36. In this example, the progress status of each process performed in the designated space is displayed in shades of colors according to the progress status of the process in the form of a process chart. According to such a display screen, progress of each process can be grasped daily.

== Labor management ==
The labor management unit 38 determines the work content based on the combination of workers, materials, and tools in each space recorded in the entrance / exit management database 22, and determines the work process, the time, and the work process for each worker. It is determined whether it has been performed, and the labor yield is automatically calculated. In addition, the determination of the work content by the combination of the worker, the material, and the tool is performed with reference to the process rule database 24 as in the process progress management unit 34. For example, in the example of FIG. 8 described above, it is determined that the double floor worker (worker B) was engaged in the construction of the double floor in the space 502 between March 15 and 9:15 to 11:52. The In this case, since the work time is 2 hours and 37 minutes, the double floor construction area of the space 502 is, for example, 10 m ² , the work time of the day is, for example, 8 hours, and the labor yield is (2 hours 37 minutes / 8 hours). ) / 10 m ² = 0.033 person · day / m ² .

  The work status display unit 40 displays the process performed in each space and the arrangement status of each worker determined by the labor management unit 38 on the screen.

  FIG. 13 shows a first example of a display screen by the work status display unit 40. On this display screen, the space where the process work of the designated type of industry is currently performed and the number of workers existing in the space are displayed.

  FIG. 14 shows a second example of a display screen by the work status display unit 40. In this display screen, on the process table for the designated industry, the processes that have been completed or the inspections by the manager have been totaled and displayed.

== Safety management ==
Based on the entrance status of each worker to each space recorded in the entrance / exit management database 22 and the scheduled work process in each space recorded in the process plan database 28, the safety management unit 42 Detects entry into a space where entry is not permitted and issues an alarm. For example, when the data illustrated in FIG. 15 is recorded in the entrance / exit management database 22 and the current scheduled work in the space 323 is “urethane” in the process plan database 28, the safety management unit 42. When a worker B who is not permitted to enter the space during the urethane work enters the space 323, the worker B is warned.

In addition, the safety management unit 42 can perform various types of safety management based on combinations with other element IDs.
For example, when a worker is present in a certain space, the necessary safety gear is not installed unless the necessary safety gear (protective cap, safety belt, license) is also present in the space. A warning to that effect can be issued. In the example shown in FIG. 16, the worker A enters the space 890 at 8:46 on March 30 and the element ID 2085 of the worker is read. At the same time, the element ID 3121 of the protective cap of the worker A is also displayed. Although it is read, the element ID of the safety belt is not read, so that a warning that the safety belt is not worn is issued.

  Further, regarding a process in a space such as a pit where a work by a plurality of persons is required, a warning can be issued when it is determined that there is only one worker in the space. In the example shown in FIG. 17, since the worker E who entered the space 16 that is a pit at 13:08 on March 30 is alone, a warning that a single work is being performed in the pit 16 is issued.

== Effects of this embodiment ==
As described above, according to the site management system of the present embodiment, an IC tag 12 is attached to each element such as materials, tools, and workers, and the IC tag 12 is provided in each space of the site. By reading with the tag reader 14, the entry / exit date and time of each element in each space can be managed. Based on the entry / exit date and time of each element managed in this way, it is possible to manage the progress of the process in each space, the working status of workers, and the unsafe situation.
