Description

  The present invention relates to a work capacity detection device and a program for detecting the work capacity of a worker on a construction site.

  Conventionally, process work time, which is a time required by an operator to perform a process work, has been managed (Patent Document 1, etc.). For example, the total of each time required for each movement (walking, bending of a waist, grasping an object, positioning, etc.) required for performing a process work is calculated using a predetermined calculation formula (eg, MOST method). By doing so, the reference process work time of the process work is obtained. Then, the reference process work time is compared with the actual process work time. Alternatively, the reference process work time may be obtained by measuring the process work time of a skilled worker with a stopwatch or the like.

  By grasping the process work time of the worker, the work ability of the worker can be grasped. That is, managing the process work time of the worker also manages the work ability of the worker. By managing the work ability of the worker, for example, the worker can be evaluated and work problems can be corrected. For example, when the process work time is longer than the reference process work time, it is understood that the work ability of the worker is lower than the reference, and in such a case, guidance for improving the work ability of the worker, Alternatively, it is possible to take measures such as changing the layout of the workshop to improve the work ability.

  While there is a work site where the work ability of the worker is managed, there is a fact that the work ability of the worker is not managed at the construction site such as a construction site. The reason is that it is practically impossible to measure the process work time of each worker, because the site manager who manages the construction site and workers has to manage multiple construction sites in a single operation. It is possible that Alternatively, since each process work at the construction site is not a simple repetitive work like the process work in a line production system, but includes a wide variety of operations, the time required for each operation can be calculated by the MOST method described above. It may be difficult to calculate the reference process work time.

  Hereinafter, embodiments according to the present invention will be described. FIG. 1 is a configuration diagram of a work capacity detection system 10 according to the present embodiment. The work capacity detection system 10 is a tablet terminal 12 as a site terminal installed at a construction site such as a construction site, a server 14 as a work capacity detection device, and a general-purpose used by a manager who manages a construction site or a worker. It is configured to include an administrator terminal 16 which is a computer. The tablet terminal 12 and the server 14, and the server 14 and the administrator terminal 16 are communicably connected to each other via a communication line 18 such as the Internet or a LAN (Local Area Network). In FIG. 1, one tablet terminal 12 and one administrator terminal 16 are shown, but the server 14 is connected to a plurality of tablet terminals 12 and a plurality of administrator terminals 16 used at a plurality of construction sites. It is possible.

  First, the outline of the operation of the work ability detection system 10 will be described. The tablet terminal 12 acquires the work start time and the work end time of the worker for each process work (for example, unit work such as sash work and unit bath work) performed at the construction site. The work start time information indicating the work start time and the work end time information indicating the work end time are transmitted from the tablet terminal 12 to the server 14. Work amount information indicating the work amount of the process work is stored in advance in the server 14, and the server 14 is based on the work start time information, the work end time information, and the work amount information transmitted from the tablet terminal 12. Then, the work ability of the worker in the process work is calculated. The work capacity in this embodiment means a work speed on the assumption that the quality of work is guaranteed to some extent.

  First, each part of the tablet terminal 12 will be described.

  The communication unit 20 is composed of, for example, a network adapter. The communication unit 20 is for communicating with the server 14 via the communication line 18. Various information is transmitted and received between the tablet terminal 12 and the server 14 by the communication unit 20. Details of these pieces of information will be described later.

  The authentication unit 22 performs an authentication process for authenticating a worker who uses the tablet terminal 12. For example, the authentication unit 22 requests the worker to input a user ID and password as authentication data, and authenticates the worker based on the input user ID and password. Alternatively, the authentication unit 22 may perform the authentication process using biometric authentication from the viewpoint of preventing the impersonation of the worker. For example, the face image of the worker may be captured using the camera unit 28 described below, and the face image of the worker may be used as the authentication data to perform the authentication process. The authentication process is performed by collating a user database (not shown) previously stored in the storage unit 30 or the storage unit 42 of the server 14 described later with the authentication data acquired by the authentication unit 22.

  The input unit 24 is configured to include, for example, a touch panel or buttons. The input unit 24 receives an instruction (operation) from the operator to the tablet terminal 12.

  The display unit 26 is composed of, for example, a liquid crystal panel or the like. Various information regarding the tablet terminal 12 is displayed on the display unit 26. Further, in this embodiment, the liquid crystal panel forming the display unit 26 is a touch panel, and the liquid crystal panel functions not only as the display unit 26 but also as the input unit 24.

  The camera unit 28 is configured to include a lens and an image sensor. The camera unit 28 is used to take an image (photograph). In particular, the camera unit 28 is used to capture a construction site image showing the performance of the process work after the process work is completed. The construction site image is attached to a daily work report, for example, and is submitted to the manager. Therefore, the imaging of the construction site image is generally performed at the construction site. A camera application (not shown) is installed in the storage unit 30 described later, and the camera unit 28 becomes operable when the user activates the camera application. When an image is captured by the camera unit 28, construction site image data is acquired. The construction site image data includes metadata including imaging time data indicating the imaging time of the construction site image data. The construction site image data is transmitted to the server 14 via the communication unit 20.

  The storage unit 30 includes, for example, a ROM (Read Only Memory) or a RAM (Random Access Memory). The storage unit 30 stores a program for operating each unit of the tablet terminal 12. In addition, the entrance / exit management application 32 that operates on the tablet terminal 12 is installed in the storage unit 30 in advance. Further, preferably, the work management application 34 is installed in the storage unit 30 in advance.

  In the entrance / exit management application 32, each worker who works at the construction site where the tablet terminal 12 is installed has an entry time (work start time), a break start time, a break end time, and the construction site. This is an application for entering the departure time (working end time) from. The tablet terminal 12 acquires the information indicating each time when the worker inputs each time using the entrance / exit management application 32. Assuming that two or more process works are not performed in one day at the construction site, the work of the worker grasped from the worker's entry time, break start time, break end time, and exit time. Based on the time, the time (process work time) required by the worker for the process work can be grasped. That is, the worker's entrance time on the day when a certain process work is started may be the work start time of the process work, and the worker's exit time on the day when the process work is finished may be the work end time of the process work. Then, the working time of the worker from the work start time to the work end time is acquired as the process work time of the process work. The information indicating each of the times acquired by the tablet terminal 12 is transmitted from the tablet terminal 12 to the server 14.

  An operation method of the entrance / exit management application 32 will be described. FIG. 2 shows an example of a screen displayed on the display unit 26 when the entrance / exit management application 32 is executed. Note that the example of FIG. 2 is an example in which the entrance / exit management application 32 is started in a state in which A man, who is A man, is logged in. In the upper area of the screen, the date, the current time, the construction site name, the name of the worker who is currently logged in, etc. are displayed. The lower area is divided into a plurality of status areas corresponding to each attendance status of the worker. In the present embodiment, the status area includes a pre-entry area indicating before entry (before work), an entry area indicating entry (working), a rest area indicating break, and an exit area indicating exit (home). It contains four areas.

  In the status area, a name tag 32a corresponding to an operator who works at the construction site where the tablet terminal 12 is installed is displayed. The information about the worker who works on the construction site is transmitted from the server 14 in advance. For example, when the name tag 32a of A man A man who is a worker who works at the construction site is displayed in the pre-entry area, it indicates that A man A man is currently not admitted.

  When mountain A A man who entered the construction site wants to change his or her attendance status to being in attendance, drag the name tag 32a of mountain A A man currently displayed in the pre-entry area with his finger or the like on the screen. , Move to the admission area. Then, the name tag 32a of A man A man is displayed in the entry area, and the time when the name tag 32a of A man A is moved is displayed on the name tag 32a. In this way, by dragging and moving the name tag 32a of the user to each area, the attendance status of the user is changed.

  When the worker moves the name tag 32a between the areas and changes the attendance status, site name data indicating the construction site name, worker data indicating the worker whose attendance status has been changed, and attendance after the change The work status change information including the status data indicating the status and the time data indicating the time when the attendance status is changed is transmitted to the server 14. The time data may be acquired based on the time information set in the tablet terminal 12, but the time data is acquired based on the time information managed by the server 14 in order to prevent falsification of the time. preferable. In the above example, the work status change information including the site name data “construction site 1”, the worker data “A mountain A man”, the time data “9:15”, and the status data “entering” is the server. 14 is transmitted.

  In the entrance / exit management application 32, a plurality of name tags 32a corresponding to a plurality of workers may be displayed, but the name tag 32a can be moved only by the name tag 32a of the currently logged-in person. Is. For example, when A man A mountain is logged in, name tags 32a other than A man A name tag 32a cannot be moved. That is, only oneself can change the attendance status of oneself. As a result, it is possible to prevent a worker from impersonating someone who changes the attendance status of another worker.

  FIG. 3 is a diagram showing another operation example of the entrance / exit management application 32. FIG. 3 shows an example of changing the attendance status to leaving when A man of mountain A finishes his work and returns home. After finishing the work, A man of A mountain logs in (authenticates) to the tablet terminal 12. Then, the entrance / exit management application 32 is activated, and the user's name tag 32a displayed in the entrance area is dragged and moved to the exit area. Then, the name tag 32a of A man A mountain is displayed in the exit area, and the time when the attendance status is changed is displayed in the name tag 32a. As a result, the attendance status of mountain A and man A is changed to leaving. In this case, work status change information including site name data “construction site 1”, worker data “A mountain A man”, time data “17:32”, and status data “exit” is sent to the server 14. Sent.

  The work management application 34 is for notifying the worker of the process work to be performed at the construction site. Further, the work management application 34 enables the worker to notify the server 14 that a certain process work is started. Further, the work management application 34 can activate a camera application to capture a construction site image.

  FIG. 4 shows an example of a screen displayed on the display unit 26 when the work management application 34 is executed. On the screen of the work management application 34, a list of processes to be worked on the construction site is displayed. For example, as shown in FIG. 4, sash work, unit bath work, cross work, joinery work, etc. are shown as the steps of the interior work to be performed at the construction site. This list may indicate the order of steps to be performed in order from the top. By confirming the screen, the worker can grasp the process to be performed or the order thereof. Information indicating the process (process information) displayed in the work management application 34 is transmitted from the server 14. The server 14 may transmit the process information every day (in this case, only the process to be worked on the day is displayed), and the process information for a certain number of days (for example, one week or one month) is collected. You may make it transmit it.

  On the screen of the work management application 34, a work start button 34a and an image capturing button 34b are displayed for each process.

  When the worker starts a certain process work, by touching the work start button 34a corresponding to the process, the tablet terminal 12 transmits the process start information for notifying the server 14 to start the process work. . The process start information includes site name data indicating a construction site name, worker data indicating a worker who has touched the work start button 34a (a worker who is logged in when touched), and the touched work start button 34a. Process data for identifying the process corresponding to, and date / time data indicating the date and time when the work start button 34a is touched are included. The time indicated by the date / time data included in the process start information may be used as the work start time. Alternatively, the time when the process start information is received by the server 14 may be used as the work start time.

  Further, when the worker finishes a certain process work, by touching the image capturing button 34b corresponding to the process work, the camera application is activated to capture a construction site image corresponding to the process work. You can The metadata included in the construction site image data imaged by the camera application activated in this way includes the site name data indicating the construction site name, the worker data indicating the worker who captured the construction site image, and the touched data. Process data for identifying the process corresponding to the captured image capturing button 34b and image capturing time information indicating the image capturing time when the construction site image is captured are included. The time indicated by the imaging time information may be used as the work end time.

  As described above, according to the work management application 34, the work start time and the work end time of a certain process work are acquired more accurately. As a result, a more accurate work capacity of the worker is calculated by the work capacity calculation unit 54 described later. In particular, when performing a plurality of process works in one day, it is preferable to use the work start time and the work end time acquired by the work management application 34.

  The control unit 36 includes a microcomputer, a CPU (Central Processing Unit), or the like. The control unit 36 controls each unit of the tablet terminal 12 according to the program stored in the storage unit 30.

  Next, each part of the server 14 will be described.

  The communication unit 40 is composed of, for example, a network adapter. The communication unit 40 is for communicating with one or a plurality of tablet terminals 12 via the communication line 18. Various information is transmitted and received between the tablet terminal 12 and the server 14 by the communication unit 40. In particular, the communication unit 40, for a plurality of workers who work at a plurality of construction sites, work start time information indicating the work start time of each process work, and work end time information indicating the work end time of each process work. To receive. That is, the communication unit 40 also functions as a time information receiving unit.

  The storage unit 42 is composed of, for example, a ROM, a RAM, a hard disk, or the like. The storage unit 42 stores a program for operating each unit of the server 14. Further, the storage unit 42 stores each database of a work content DB (database) 44, a work time DB 46, a process work time DB 48, and a work ability DB 50. Each database will be described below.

  The work content DB 44 stores information indicating the content of each process work performed at each construction site managed by the server 14 (that is, each construction site where the tablet terminal 12 connectable to the server 14 is installed). In particular, the work content DB 44 stores work amount information indicating the work amount of each process work. In this way, the storage unit 42 also functions as a work amount information storage unit. The work content DB 44 is created in advance by the administrator and stored in the storage unit 42.

  FIG. 5 shows an example of the work content DB 44. The work content DB 44 has a table format, and one record corresponds to one process at one construction site. As shown in FIG. 5, one record of the work content DB 44 includes information for identifying a construction site, information for identifying a process, work date information indicating a work date of the process work, and work for performing the process work. The worker information indicating the worker and the work amount information indicating the work amount of the process are associated with each other. For example, referring to the record at the top of FIG. 5, at the “construction site 1”, the process work of the process “sash work” is performed on the work day “September 1, 2016 to September 2, 2016” by the worker. It is planned to be carried out by "A mountain A man", and it is shown that the work amount of the sash work is "20 square meters". In the present embodiment, the number of square meters is stored as the work amount information, but as the work amount information, another index may be adopted as long as it indicates the work amount of the process work. The process information displayed on the work management application 34 is transmitted from the server 14 to the tablet terminal 12 based on the work content DB 44.

  The working time DB 46 stores time information indicating working hours of each worker at each construction site managed by the server 14. The working time DB 46 is input by each worker at each construction site using the entrance / exit management application 32, and based on the work status change information transmitted from one or more tablet terminals 12 to the server 14, a control unit described later. 52.

  FIG. 6 shows an example of the working time DB 46. The working time DB 46 is also in a table format, and one record corresponds to one worker in one day. As shown in FIG. 6, one record of the working time DB 46 includes information indicating a construction site, a working day, a worker, a work start time, a work end time, a break start time, and a break end time. For example, the record at the top of FIG. 6 will be described. As described above, in the entrance / exit management application 32, Ms. A and M. A have their own name tags 32a at 9:15 on September 1, 2016 (see FIG. 2). (See) is moved to the admission area, the site name data “construction site 1”, worker data “A mountain A man”, time data “9:15”, and status data “admission” are included. The work status change information is transmitted to the server 14. Based on the work status change information, the construction site name "construction site 1", the work day "2016/9/1", the worker name "A mountain A man", the work start time "9:15" A new record including "" is added to the working time DB 46. In this way, the working time DB 46 is updated every time the time data or the like input to the entrance / exit management application 32 is received from the tablet terminal 12. In addition, in the entrance / exit management application 32, when A man A moves his name tag 32a to the exit area at 17:32 on September 1, 2016, the site name data "construction site 1" and the worker The work status change information including the data “A mountain A man”, the time data “17:32”, and the status data “Exit” is transmitted to the server 14. As in this case, when a record including the work site name data and the worker data included in the work status change information and the work day that is the date of the current day already exists in the working time DB 46, a new record is not added. The time data “17:32” included in the work status change information is stored at the work end time of the corresponding record.

  In the process work time DB 48, for each process work at each construction site managed by the server 14, a work start time when each worker starts the process work, a work end time when the worker finishes the process work, Also, the time required for the process work (process work time) is stored. The process work time DB 48 is also constructed by the control unit 52, which will be described later, based on each piece of information transmitted from the tablet terminal 12 to the server 14.

  FIG. 7 shows an example of the process work time DB 48. The process work time DB 48 is also in a table format, and one record corresponds to one process at one construction site. As shown in FIG. 7, one record of the process work time DB 48 includes information indicating a construction site, process, worker, work start time, work end time, and process work time. In the present embodiment, in the work management application 34, the time when the worker touches the work start button 34a (see FIG. 4) is the work start time, and the time when the worker images the construction site image is the work end time. .

  For example, the record at the top of FIG. 7 will be described. As described above, in the work management application 34, the man A and the man A press the work start button 34a corresponding to the sash work at 9:27 on September 1, 2016. When you touch the minute, the process start information including the site name data “Construction site 1”, the worker data “A mountain A man”, the process data “Sash work”, and the date and time data “2016/9/1 9:27” Is transmitted to the server 14. Based on this, a new record including the construction site name "construction site 1", the process name "sash construction", the worker name "A mountain A man", and the work start time "2016/9/1 9:27" Is added to the process work time DB 48. Similarly, if the construction site image data (metadata) transmitted from the tablet terminal 12 includes the site name data “construction site 1”, the worker data “A mountain A man”, and the process data “sash construction”. Then, the corresponding record is specified from the process work time DB 48 based on these data. Then, the work end time of the identified record is added based on the imaging time information (here, “2016/9/2 18:01”) included in the construction site image data.

  The process work time is the work time of the worker between the work start time and the work end time stored in the process work time DB 48. The process work time is calculated based on the work start time and the work end time in the work content DB 44, the work time DB 46, and the process work time DB 48.

  The sash construction by A man A in construction site 1 shown in the record at the top of FIG. 7 will be described. From the work content DB 44, it can be understood that the sash work at the construction site 1 is performed over two days, September 1st and September 2nd, 2016. Therefore, the process work time is calculated based on the work time of A man A on September 1st and September 2nd, 2016. In the present embodiment, the work start time is the time when the work start button 34a of the work management application 34 is touched, and the work end time is the imaging time of the construction site image. Therefore, as the working time on September 1 which is the construction start date of the sash construction, from the work start time “9:27” stored in the process work time DB 48, the work end time “17 : 32 "excluding the break time. Further, as the work time on September 2 which is the construction end date of the sash work, the work start time “8:31” indicated by the work time DB 46 is the work end time “18 stored in the process work time DB 48. : 01 ”excluding the break time. In this way, "15h26m (15 hours 26 minutes)" is calculated as the process work time.

  In the present embodiment, the work start time is the time when the work start button 34a of the work management application 34 is touched, and the work end time is the image pickup time of the construction site image. The work start time of may be the work start time, and the work end time of the construction end date of the process work may be the work end time. For example, as for the sash work of A man and A man at the construction site 1, the work start time (“2016/9/1 9:15”) on September 1, which is the construction start date, may be used as the work start time. The work end time (“2016/9/2 18:11”) on September 2nd, which is the construction end date, may be set as the work end time. In this case, the process work time is calculated based on the work content DB 44 and the working time DB 46.

  The work ability DB 50 stores the work ability of each worker for each process work at each construction site managed by the server 14. The work capacity DB 50 is constructed by a work capacity calculation unit 54 described later based on the work content DB 44 and the process work time DB 48. The work capacity DB 50 can be browsed from the administrator terminal 16.

  FIG. 8 shows an example of the work ability DB 50. The work capacity DB 50 is also in a table format, and one record corresponds to one process and one worker. As shown in FIG. 8, one record in the work ability DB 50 includes information indicating a worker, a process, and work ability. As an index indicating the work capacity, the amount of work per unit time that the worker can perform in the process, and the working time per unit work amount of the worker in the process (the work required to perform the unit work amount) At least one of (time) is calculated. In the present embodiment, both of the above indexes are calculated. A specific method of calculating the work ability will be described later.

  The control unit 52 includes a CPU (Central Processing Unit) and the like. The control unit 52 controls each unit of the server 14 according to the program stored in the storage unit 42. The control unit 52 also functions as the work ability calculation unit 54 according to the program.

  The work ability calculation unit 54 is based on the work content DB 44 (especially the work amount information thereof) and the process work time DB 48 (the process work time calculated based on the work start time information and the work end time information thereof). , Calculate the work ability of each worker in each process work. The work ability is calculated for each group of the process and the worker shown in the work content DB 44. The work ability calculated by the work ability calculating unit 54 is stored in the work ability DB 50 as described above.

  The processing of the work ability calculation unit 54 will be described by taking the sash work by A man A on the construction site 1 as an example. According to the work content DB 44 (see FIG. 5), it is understood that the work amount of the sash work performed by A man A in the construction site 1 is 20 square meters. Further, according to the process work time DB 48 (see FIG. 7), it is understood that the process work time related to the sash work of A man and A man at the construction site 1 is 15 hours and 26 minutes.

  Therefore, the work ability calculation unit 54 calculates an index value obtained by dividing the work amount by the process work time as the work amount per unit time. In this example, the work amount “20 square meters” is divided by the process work time “15 hours and 26 minutes (15.433 hours)” to calculate “1.296 (square meters / h)” as the work amount per unit time. . Further, the work capacity calculating unit 54 calculates an index value obtained by dividing the process work time by the work amount as the work time required to perform the unit work amount. In this example, "0.772 (h / square meter)" obtained by dividing the process work time "15 hours 26 minutes (15.433 hours)" by the work volume "20 square meters" is the work time required to perform the unit work volume. Is calculated as

  Further, the work ability calculation unit 54 calculates the work ability of each worker at each construction site for each process. Thereby, the work capacity of each worker for one process is calculated. For example, referring to FIG. 8, the work abilities of the worker “A mountain A man” and the worker “B field B male” are calculated for the process “sash work”. As shown in FIG. 5, although the amount of work actually performed is different between the worker “A mountain A man” and the worker “B field B male”, the work amount per unit time or the unit is calculated as the work ability. Since the work time required to perform the work amount is calculated, it is possible to directly compare the work ability among a plurality of workers in one process.

  As described above, according to the present embodiment, it is possible for the manager to detect the work ability of the worker without having to go to the construction site and directly measure the process work time of the worker. The work ability is stored in the work ability DB 50, which can be viewed from the administrator terminal 16. This brings about the following effects.

  For example, when the contents shown in FIG. 8 are stored as the work ability DB 50, the administrator can grasp the work ability of each worker for each process by browsing the work ability DB 50. According to this, the worker to be assigned to each process can be selected based on the work ability of the worker. For example, for a process that has a short work period and needs to be performed early, it is possible to have a worker having a relatively high work capacity perform the work.

  Further, since the work ability of each worker in each process is stored in the work ability DB 50, the work ability DB 50 can grasp each worker's favorite process or unfavorable process. For example, in the example of FIG. 8, it can be understood that the man A and the man A have higher work ability than the man B and man B for sash work. On the other hand, regarding unit bus construction, it is understood that B Tao B Tao has higher work ability than Ao A Man. As described above, the work capacity DB 50 also indicates the work capacity characteristics of the workers, and the manager can also assign each worker to an appropriate process based on the work capacity characteristics.

  If the work capacities of a large number of workers are calculated for a certain process, the work capacity calculation unit 54 divides the sum of the work capacities of the workers by the number of workers to calculate the average work of the process. Ability can be calculated. Then, the manager can evaluate the work ability of the attention worker based on the difference between the calculated average work ability and the work ability of the attention worker. For example, if the work ability of the noticed worker is higher than the average work ability, the noticed worker can be highly evaluated at least for the work of the process. On the other hand, when the work ability of the attention worker is lower than the average work ability, the attention worker can be evaluated as low at least for the work of the process, and the cause of the low work ability can be investigated and corrected. It will be possible.

  The processing flow of the server 14 will be described below with reference to the flowchart shown in FIG. At the start of the flowchart of FIG. 9, it is assumed that the work content DB 44 stores the content shown in FIG.

  In step S10, the worker operates the entrance / exit management application 32 to transmit the work status change information from the tablet terminal 12, and the server 14 receives the work status change lock. Here, it is assumed that the work status change information including the site name data “construction site 1”, the worker data “A mountain A man”, the time data “9:15”, and the status data “entering” is received. To do.

  In step S12, the control unit 52 updates the working time DB 46 based on the received work status change information. Here, a record including the construction site name “construction site 1”, work date “2016/9/1”, worker “A mountain A man”, and work start time “9:15” is added.

  In step S14, when the worker A mountain A man touches the work start button 34a corresponding to the sash work in the work management application 34, the process start information is transmitted from the tablet terminal 12 to the server 14. The server 14 receives the process start information.

  In step S16, the control unit 52 updates the process work time DB 48 based on the received process start information. Here, a record including the construction site name "construction site 1", the process "sash construction", the worker "A mountain A man", and the work start time "2016/9/1 9:27" is added.

  In step S18, the control unit 52 determines whether or not the work status change information is further received from the tablet terminal 12. For example, in the entrance / exit management application 32, A man A moved the name tag 32a to the resting area, returned the name tag 32a to the entering area, moved the name tag 32a to the leaving area, the next day Each time the name tag 32a is moved from the pre-entry area to the in-entry area, the tablet terminal 12 transmits the work status change.

  In step S20, the control unit 52 updates the working time DB 46 based on the received work status change information.

  In step S22, the control unit 52 determines whether or not the construction site image data corresponding to the sash construction at the construction site 1 is received from the tablet terminal 12. The processes of steps S18 to S22 are repeated until the construction site image data is received. Here, it is assumed that the working time DB 46 has the contents shown in FIG. 6 due to the processing of step S20 that is repeatedly executed.

  When the mountain A man starts the camera application from the work management application 34 or the like to capture a construction site image corresponding to the sash construction, the tablet terminal 12 transmits the construction site image data to the server 14. Here, the metadata of the construction site image data is the site name data “construction site 1”, worker data “A mountain A man”, process data “sash construction”, and imaging time information “2016/9/2 18 : 01 ”is included.

  In step S24, the control unit 52 updates the process work time DB based on the received construction site image data. The control unit 52 adds the record added in step S16 based on the site name data “construction site 1”, the worker data “A mountain A man”, and the process data “sash construction” included in the construction site image data. Specify. Then, as the work end time of the identified record, the imaging time information “2016/9/2 18:01” included in the construction site image data is stored.

  In step S26, the control unit 52 is based on the work content DB 44, the working time DB 46, the work start time added to the process work time DB 48 in step S16, and the work end time added to the process work time DB 48 in step S24. , Calculate the process work time. Here, “15h26m” is calculated as the process work time as described above.

  In step S28, the work ability calculation unit 54 calculates the work ability of A man A man for sash work based on the work content DB 44 and the process work time DB 48. The details of the work capacity calculation processing are as described above.

  In step S30, the work ability calculation unit 54 stores the work ability calculated in step S28 in the work ability DB 50.

  Although the embodiment according to the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the work ability for each worker is calculated, but the work ability for a worker group including a plurality of workers may be calculated. For example, “A mountain A man” in the above embodiment may be “A mountain construction”. In this case, the work start time in the working time DB 46 for mountain A construction may be, for example, the time when all the workers of mountain A construction enter the construction site. Further, the work end time may be, for example, the time when all the workers of the mountain A construction leave the construction site. Further, the break time on each work day may be, for example, the average of the break times of all the workers of the mountain A construction.
