[0008] Hereinafter, an embodiment will be described with reference to the drawings. As shown in Fig. 1, a work man-hour counting device 1 includes a management device 2 installed in, for example, an office space, and a terminal device 4 and a reading device 5 arranged in a work space 3. These devices are connected to be able to communicate with each other via a network 7 via a relay device 6. In the case of this embodiment, the work man-hour counting device 1 is also connected to be able to communicate with another management system 8, and acquires and uses various information as described later.

[0009] The work spaces 3 include areas where work directly related to manufacturing, such as product assembly and processing, is carried out, as well as areas such as conference rooms where work not directly related to manufacturing is carried out, and terminal devices 4 and reading devices 5 are appropriately arranged according to the work content of each work space 3.

[0010] For example, in the work space 3A, a terminal device 4 and a reader 5 are arranged, and the reader 5 is controlled by the terminal device 4. In addition, in the work space 3B, the reader 5 and a pacemaker 9 that notifies the progress of work and the like are arranged, and the reader 5 and the pacemaker 9 are controlled by the management device 2. This pacemaker 9 is appropriately arranged in the work space 3 where it is necessary to notify the progress by displaying on the display screen of the terminal device 4 or by lighting a dedicated indicator lamp.

[0011] In addition, in the work space 3C and the work space 3D, a terminal device 4 and a reading device 5 are arranged in the work space 3C, and the reading devices 5 in the work space 3C and the work space 3D are controlled by the terminal device 4. Note that the configuration shown in Fig. 1 is an example, and the number and arrangement of the devices included in the work man-hour counting device 1 or the number of work spaces 3 can be set appropriately.

[0012] 2, the management device 2 is configured as a so-called computer, and is connected to a management display unit 10 configured as a display, a management input unit 11 configured as a keyboard and mouse, and a printer 12 for printing instructions. The management device 2 is equipped with a control unit (not shown), a storage unit 13 for storing various information, and a communication unit 14 for communicating with the terminal device 4 and the like. The control unit controls the entire management device 2, and by executing a program, realizes each of the functional blocks described below in software.

[0013] Note that the number, types, and arrangement of functional blocks shown in FIG. 2, including the terminal device 4 side, are merely examples, and the functional blocks may be arranged on different device sides, or the functional blocks on the management device 2 side and the terminal device 4 side may be integrated to perform processing using a single functional block.

[0014] The serial number management unit 20 manages serial numbers to be the objects of work based on serial number information, process information, board information, and unit information. The serial number information is information indicating a serial number that is individually assigned to each order, and the process information is information indicating each process included in the serial number. Depending on the work, one serial number may be composed of multiple boards, and multiple units may be built into one board. In this case, the work order is assembling the units in a dedicated area, assembling the boards in multiple processes, attaching the completed units to the boards, and finally connecting the multiple boards to make one control board. In that case, work history is collected for each work by unit number, board number, and serial number. Therefore, the board information includes information for performing work on a board basis, and the unit information includes information for performing work on a unit basis. These pieces of information are acquired from the management system 8 and stored in the memory unit 13.

[0015] The instruction creation unit 21 creates instructions and outputs them from the printer 12 as a checklist 22 or a unit instruction 23. As shown in Fig. 3, the checklist 22 is a paper medium on which the serial number, coded information (M) that codes the serial number, items to be checked in each process, etc. are printed. The unit instruction 23 is a paper medium on which the unit number, coded information (M) of the unit number, work content in the unit, which is a work unit, etc. are printed.

[0016] The check sheet 22 and the unit instruction sheet 23 are moved to the work space 3 together with the work object, and the coded information is read by an optical reading device 5A such as a barcode reader. Note that, although a one-dimensional code such as a barcode is used as the coded information in this embodiment, a two-dimensional code can also be used.

[0017] The linking unit 24 links the serial number with the serial number tag 25. The serial number tag 25 is a card-type so-called RF tag (Radio Frequency tag) with a built-in wireless unit 26 shown as RF in Fig. 3. This serial number tag 25 has a unique identifier recorded therein, for example, "GD001", and coded information (M), such as a barcode that encodes the identifier, written on its surface.

[0018] The serial number tag 25 moves through the work space 3 together with the work object, and the serial number linked to the identifier is obtained by reading the coded information with the optical reader 5A or by reading the identifier with the wireless reader 5B in each work space 3. This makes it possible to obtain the serial number by reading the identifier of the serial number tag 25, even without providing a writing device for writing information to the serial number tag 25.

[0019] The worker management unit 27 stores worker information such as a worker number and name assigned to each worker, qualification information indicating the work qualifications held by the worker, and affiliation information indicating the affiliation of the worker, in association with each other. This information can be acquired from another system that associates the worker with the worker number and records the worker number on the worker tag 28. The worker number is recorded on the worker tag 28 shown in Fig. 3 and is written as coded information (M) on the surface of the worker tag 28. This worker tag 28 moves with the worker, and the worker number is acquired by reading it with the optical reader 5A or the wireless reader 5B in each work space 3.

[0020] The acquisition unit 29 is composed of a serial number acquisition unit 291 that acquires the serial number for the work object based on information read by the reading device 5 arranged in the work space 3 from the checklist 22, unit instruction sheet 23, serial number tag 25 or worker tag 28, and a worker number acquisition unit 292 that acquires the worker number.

[0021] The data creation unit 30, details of which will be described later, includes a work start data creation unit 301 that creates work start data including at least the serial number and the start time of the work when work has started, based on the serial number and worker number acquired by the acquisition unit 29, and a work end data creation unit 302 that creates work end data including at least the serial number and the end time of the work when the work has ended.

[0022] The interruption / resumption unit 31, details of which will be described later, when it receives an input to interrupt a task after it has started, stores the work content up to that point, creates work end data for the current task, and creates new work start data for the task to be performed after the interruption. The interruption / resumption unit 31 also includes an interruption processing unit 311 that creates work end data for the task performed after the interruption when it receives an input to resume the task after the interruption, and a resume processing unit 312 that creates new work start data for the work content stored at the time of interruption.

[0023] The man-hour counting unit 32, which will be described in detail later, counts the man-hours for each serial number based on the work start data and work end data, and stores the counted man-hours as work history data. The presentation unit 33, which will be described in detail later, presents the counted man-hours and the target man-hours set in advance for the serial number, for example, by displaying them on the management side display unit 10. The non-conformity processing unit 34, which will be described in detail later, instructs correction work when the work result is determined to be non-conforming because it does not meet a predetermined quality standard. Note that the determination as to whether the work result meets the predetermined quality standard is made, for example, by another management system 8, and the work man-hour counting device 1 acquires the determination result.

[0024] The terminal device 4 is configured as a so-called computer, and is connected to a terminal display unit 35 configured as a display, a terminal input unit 36 ​​configured as a keyboard, a mouse, etc., and is communicatively connected to the management device 2 and the like via a terminal communication unit 37. The terminal device 4 is also provided with an optical reader 5A or a wireless reader 5B depending on the environment of the work space 3. It is sufficient to provide at least one of the optical reader 5A and the wireless reader 5B in the work space 3, but both may be provided.

[0025] The terminal device 4 includes a terminal side acquisition unit 29A having a terminal side serial number acquisition unit 291A and a terminal side worker number acquisition unit 292A that realize the same function as the acquisition unit 29, a terminal side data creation unit 30A having a terminal side work start data creation unit 301A and a terminal side work end data creation unit 302A that realize the same function as the data creation unit 30, a terminal side interruption resumption unit 31A having a terminal side interruption processing unit 311A ​​and a terminal side resumption processing unit 312A that realize the same function as the interruption resumption unit 31, a terminal side man-hour counting unit 32A that realizes the same function as the man-hour counting unit 32, and a terminal side storage unit 38 that stores information similar to that of the storage unit 13. Therefore, the terminal device 4 can substitute for a certain degree of processing such as creating work start data, work counting data, or interruption time data. Therefore, by transmitting the processing results of the terminal device 4 to the management device 2, the management device 2 can reduce the load on the network 7 and can also handle an increase in the number of work spaces 3 and readers 5.

[0026] Next, the operation of the above-mentioned configuration will be described. As described above, conventionally, there was no mechanism for collecting the man-hours for each serial number assigned to each order, and the validity of the man-hours could not be guaranteed. Therefore, in this embodiment, it is possible to appropriately collect the man-hours for each serial number. In the following, (1) a manual registration process that requires the operator to register the process when tallying up the man-hours, (2) an automatic registration process that does not require the operator to register, (3) a process for registering other work, (4) a process for tallying up and presenting the man-hours, and (5) an example of linking with other systems will be described individually.

[0027] (1) Manual registration Manual registration is a method that is basically performed in the work space 3 where the terminal device 4 is located. Below, the processing by the work man-hour counting device 1 will be explained, but first, in order to make the processing flow easier to understand, the flow of operations by the worker will be briefly explained.

[0028] Manual registration requires the operation of registering processes and the like using an operation terminal, so as shown in FIG. 5, an operation screen for the manual registration tool is displayed on the terminal display unit 35. Then, when the worker reads the worker tag 28 with the reading device 5, the worker number is obtained and the name of the worker corresponding to that worker number is displayed. In this state, when the worker clicks on an area where the status is "waiting for registration", a selection screen for selecting a process is displayed, and the worker selects the process to be worked on from a pull-down menu. At this time, if the worker has the work qualifications for the selected process, "work qualifications available" is displayed, and the worker can carry out the work. In addition, workers can register work not only by serial number, but also by panel or unit.

[0029] Next, the worker registers the serial number by reading the instruction sheet or serial number tag 25 with the reading device 5, and then selects the station where the work is to be registered and starts the work, and the status becomes "in work". In addition, while working, the progress such as the work start time, work time, or progress against the target time is displayed and updated in real time at the bottom of the screen. At this time, the worker can register multiple serial numbers. This is because, for example, in an actual work site, when the same parts are required for different serial numbers, it is assumed that those parts will be assembled together in one work space 3. Note that the station referred to here simply indicates a place where data is registered, and is unrelated to the work space 3 where the actual work is performed.

[0030] To enable such an operation, the work man-hours tallying device 1 executes a manual registration process shown in Fig. 4. Note that since each process shown in Fig. 4 is executed by the functional blocks of the management device 2 and the terminal device 4 in cooperation with each other, the following description will focus on the work man-hours tallying device 1 as the subject of the process.

[0031] When the work man-hours totalizing device 1 starts the manual registration process, it acquires the worker number (S101) and acquires the process (S102). At this time, the process can be registered not only by serial number but also by panel or unit. Next, the work man-hours totalizing device 1 judges whether the worker is qualified to work (S103), and if the worker is not qualified to work (S103: NO), it displays a warning using text or a warning color indicating that the worker is not qualified to work (S104), and waits for a cancellation operation (S105).

[0032] If there is no cancel operation (S105: NO), the work man-hour totalizing device 1 proceeds to step S102, making it possible to deal with an operational error such as a simple wrong selection. If there is a cancel operation (S105: YES), the work man-hour totalizing device 1 ends the process as is, thereby preventing an unqualified worker from performing the work.

[0033] In response to this, if the worker is qualified to do the work (S103: YES), the work man-hour totalizing device 1 acquires the serial number (S106) and creates work start data (S107).Then, if there is no interrupt operation to interrupt the work (S108: NO), no registration of the work to another work by the same worker (S109: NO), and no end operation to end the work (S110: NO), the work man-hour totalizing device 1 proceeds to step S108, whereas if there is an end operation (S110: YES), the work end data is created (S112) and the process ends.

[0034] In this case, the worker clicks on the area on the operation screen where the status is "Working" to display the operation screen shown in FIG. 6, and ends the work by clicking on the hatched area "Finish". This changes the status on the operation screen to "Work Completed". This allows data to be collected that indicates which worker worked on a certain serial number and how long it took. Note that in this embodiment, the work start data and the work end data are created as separate data, but it is also possible to create work data that integrates both.

[0035] Incidentally, while it is possible that a worker may forget to perform the end operation when the work is finished, it is considered that the possibility of forgetting to register when the work is started is relatively low. Therefore, when the same worker is registered for another work while the work is in progress (S109: YES), the work man-hour counting device 1 creates work end data for the current work (S111) and ends the process. This reduces the risk of a large discrepancy in the end time of the work, and prevents the recording of contradictory work results, such as the same worker working on multiple processes at the same time.

[0036] It is also assumed that work will be interrupted during actual work. Reasons for interrupting work may be related to the serial number or unrelated to the serial number. It is also assumed that work will be restarted after it has been interrupted. Therefore, when an interruption operation is performed during work (S108: YES), the work man-hour counting device 1 records the current work content as work interruption data (S112), creates work end data for the current work (S113), and then creates work start data for the work that was the reason for the interruption (S114).

[0037] In this case, the worker operates as follows: on the operation screen, click on the area where the status is "In work" to display the interruption screen shown in FIG. 7; then click on the "Interrupted" area to display a screen for selecting the reason; by selecting the appropriate reason, for example the hatched reason B, work end data and work interruption data for the current work, as well as work start data for the work with reason B, are created.

[0038] Then, when a resume operation is performed during the interruption of the work to indicate that the work is to be resumed (SS115: YES), the work man-hour counting device 1 creates work end data for the work that was being performed during the interruption (S116), re-registers the intraday work that was being performed before the interruption (S117), creates work start data for the re-registered work (S118), and proceeds to step S108. At this time, the worker can click on the area in the operation screen shown in Fig. 8 where the status is "interrupted" to display the operation screen for resuming the work, and can resume the work that was being performed before the interruption by clicking on the hatched "resume" area.

[0039] In this way, the work man-hour totalizing device 1 can totalize the actual work hours of a worker by manual registration in which the worker performs an operation to register a process or an operation to suspend or resume a work.

[0040] (2) Automatic registration Automatic registration is a method of reading information from the serial number tag 25 and the worker tag 28 using the wireless reader 5B, and automatically registering information such as the process. Note that the automatic registration process described below is executed by the functional blocks of the management device 2 and the terminal device 4 in cooperation with each other, so the process will be described with the work man-hour counting device 1 as the subject of the process.

[0041] First, as described above, the serial number tag 25 has an identifier and a serial number linked by the linking unit 24. Specifically, the serial number tag 25 has an identifier, for example, "GD001" and a serial number, for example, "SAG2301A001", linked in advance by a linking tool shown in Fig. 9. Similarly, the worker tag 28 has a worker number, for example, "P001A001", associated in advance by the worker management unit 27 with information such as the worker's name, work qualification, or affiliation, for example, "YAMADA TARO".

[0042] For work spaces 3 that support automatic registration, shop information indicating what process will be performed is preset, such as "semi-assembly 1" and "semi-assembly 2" as shown in Fig. 11. The shop information may be set by the terminal device 4, or, in the case of a work space 3 where no terminal device 4 is installed, by the management device 2 or a terminal device 4 installed in another work space.

[0043] The work man-hour counting device 1 executes the automatic registration process shown in Fig. 10, judges whether the worker number and serial number have been acquired (S201), and waits until both the worker number and serial number have been acquired (S201: NO). Then, when the worker places the worker tag 28 and serial number tag 25 at a predetermined position near the wireless reading device 5B, the worker number and identifier are read by the wireless reading device 5B. At this time, the work man-hour counting device 1 can read multiple worker tags 28 for one serial number tag 25, allowing multiple people to work on one process.

[0044] 11, when a serial number tag 25 having an identifier "GD001" is read in a work space 3 where shop information for "semi-finished process 1" is registered, the work man-hour counting device 1 acquires the serial number "SAG2301A001" linked to the identifier. In addition, when the worker number is acquired, the work man-hour counting device 1 displays the worker number and name on the screen. Note that the serial number and the worker number can be acquired in any order.

[0045] Then, when the work man-hour counting device 1 acquires both the serial number and the worker number (S201: YES), it judges whether the worker is qualified to work (S202), and if the worker is not qualified to work (S202: NO), it displays a warning indicating that the worker is not qualified to work (S203), and then proceeds to step S201. This prevents the work from being performed by a worker who is not qualified to work.

[0046] On the other hand, if the worker is qualified to work (S202: YES), the work man-hour counting device 1 creates work start data (S204). As a result, the "Semi-assembly 1" area in Fig. 11 is switched to a color, for example, green, indicating that work is in progress. In other words, when the worker tag 28 and the serial number tag 25 are placed in the predetermined positions, it is automatically determined that the worker is present in the work space 3 and that the work target is present in the work space 3, and therefore work has started. Note that in Fig. 11, the fact that work is in progress is indicated by hatching.

[0047] When the work is started, the work man-hour counting device 1 judges whether or not at least one of the serial number and the worker number can no longer be acquired (S204), and if both can be acquired (S204: NO), the work man-hour counting device 1 waits, assuming that the work is continuing. On the other hand, if at least one of the serial number and the worker number can no longer be acquired (S204: YES), the work man-hour counting device 1 creates work end data (S206) and ends the process. In other words, when the worker puts down the work and moves out of the work space 3 carrying the worker tag 28, or when the serial number tag 25 is transported out of the work space 3 together with the work object, the end of the work is automatically determined.

[0048] In this way, the work man-hour counting device 1 is capable of automatically registering and counting the actual work hours of workers by using the serial number tag 25 and the worker tag 28.

[0049] (3) Registering other tasks In actual work sites, there are indirect tasks that are difficult to associate with production numbers and tabulate, such as making jigs and inspecting equipment, and non-work tasks that are not directly related to production numbers, such as cleaning and skill training. Tabulating the results of these tasks is considered to be significant in production management. For this reason, the work man-hour tabulation device 1 is capable of collecting the work results of indirect tasks and non-work tasks. When collecting the work results of indirect tasks and non-work tasks, the tasks are basically registered using an operation terminal, and the flow of this will be explained below. However, the work results of indirect tasks and non-work tasks can also be collected by clicking the "indirect / non-work" area when interrupting a manually registered task, as shown in Figure 6.

[0050] 12, the work man-hour counting device 1 determines whether or not the worker number has been acquired (S301), and if not (S301: NO), waits. On the other hand, if the work man-hour counting device 1 acquires the worker number (S301: YES), it registers the work content (S302) and creates work start data (S303).

[0051] In this case, as shown in Fig. 13 at the start of work, the work registration tool is displayed on the terminal display 35. Then, when the worker places the worker tag 28 at a predetermined position on the wireless reader 5B, or when the coded information is read by the optical reader 5A, the worker number is registered and the worker name is displayed, and several work reasons are presented for each work. Then, the worker registers the work content by selecting the corresponding reason. In the case of Fig. 13, the state in which "Reason B" for indirect work has been selected is shown diagrammatically by hatching. After the worker number is registered, the worker tag 28 is moved away from the predetermined position and carried by the worker.

[0052] After creating the work creation data, the work man-hour counting device 1 again determines whether or not the worker number has been acquired (S304), and if not (S304: NO), it waits. However, if the worker number has been acquired (S304: YES), it displays a confirmation dialog as shown in FIG. 13 as the work completion time and waits for an end operation to be performed (S305). When the worker performs an operation to end the current work, it determines that an end operation has been performed (S305: YES), creates work end data (S305), and ends the processing.

[0053] In this way, the work man-hour totalizing device 1 is capable of collecting the work results of indirect work and non-working work together with the work content.

[0054] (4) Counting man-hours and comparing with target man-hours The work man-hour counting device 1 counts the man-hours for each worker and the man-hours for each serial number as work results based on the work start data and the work end data, and presents the counted work results and the target man-hours. Specifically, the work man-hour counting device 1 executes the counting process shown in Fig. 14, counts the work results for each worker number (S401), counts the work results for each serial number (S402), obtains the target man-hours set for each serial number (S403), and presents the work results and the target man-hours (S404).

[0055] At this time, for a task in which multiple serial numbers are registered, the work man-hour counting device 1 evenly allocates the work time to each serial number and counts it up. Also, when multiple workers are registered for the same process with the same serial number, the work man-hour counting device 1 sums up the work time.

[0056] When the tallying is complete, as shown in FIG. 15, the work man-hours for each worker are displayed on the management display unit 10 in a graph with the horizontal axis representing time, for example, along with the work content and the work time. In FIG. 15, different hatching patterns are used to show different work content. In this case, the work man-hours for a desired date can be displayed by changing the "display date." Also, by selecting "shop," it is possible to switch to a list display by panel, unit, or department. This allows the details of work performance to be grasped by process, worker, or department, making it possible to appropriately evaluate work performance.

[0057] Also, by clicking "Display by serial number," it is possible to switch to a display of work man-hours by serial number, as shown in Fig. 16. In the case of Fig. 16, for each serial number, a list of items is displayed, such as "Work man-hours" indicating the totaled man-hours, "Status" indicating whether the work for the serial number has been completed or not, "Target man-hours" indicating the man-hours set for the serial number, "Comparison" indicating the degree of agreement between the work man-hours and the target man-hours, and "PM change" indicating whether the target time for the pacemaker 9 (PM) needs to be changed.

[0058] For example, for a case with a serial number of "zzzzzzz", the work man-hours are 12.9, the status is completed, i.e., all work is completed, the target man-hours are 13.5, and there is a large discrepancy between the work man-hours and the target man-hours, indicating that the target time for the pacemaker 9 needs to be reviewed. Note that the display form shown in FIG. 16 is an example, and is not limited to this.

[0059] Therefore, for example, when the manager clicks on "zzzzzzz", the details of the man-hours for each process for that model number are displayed, and the manager can identify the process where the deviation from the target man-hours has become large. In this case, it shows that there is a slight deviation from the target man-hours for process D, and a large deviation from the target man-hours for process E.

[0060] Although not shown, by clicking on process E, the workers involved in process E and their work results are displayed in the format shown in Fig. 15, making it possible to verify the deviation. The criteria for determining the magnitude of deviation, here the criteria for determining whether or not a PM change is necessary, may be set appropriately depending on the work content, for example, whether or not the deviation from the target man-hours is a predetermined percentage or more.

[0061] In this way, the work man-hour totalizing device 1 is capable of totalizing and presenting the actual man-hours for each worker and for each serial number.

[0062] (5) Examples of integration with other systems The work man-hour counting device 1 executes the nonconformity processing shown in Fig. 17, acquires the serial number and process determined to be nonconformant (S501), sets the work required for correction (S502), adds a process for the correction work to the serial number (S503), and instructs the work (S504). In this case, the work man-hour counting device 1 can acquire the process determined to be nonconformant and its serial number from the system that performs quality control. In this way, by adding a process to the serial number and instructing the work, it is possible to prevent work errors and to properly count the work man-hours for the serial number.

[0063] Furthermore, the work man-hour counting device 1 can be configured to obtain the working status from a time attendance management system, and present the working status and the work results counted by the work man-hour counting device 1, as shown in Fig. 18. This allows the working status and the work results counted by the work man-hour counting device 1 to be compared and understood, making it possible to correct registration errors and the like, and to obtain appropriate counting results of the work results.

[0064] According to the embodiment described above, the following effects can be obtained. The work man-hour counting device 1 comprises a serial number acquisition unit which acquires the serial number of the work target, a worker number acquisition unit which acquires a worker number individually assigned to the worker, a work start data creation unit which creates work start data including at least the serial number and the start time of the work when work is started, a work end data creation unit which creates work end data including at least the serial number and the end time of the work when the work is ended, a man-hour counting unit 32 which counts the work man-hours for each serial number based on the work start data and the work end data, and a presentation unit 33 which presents the counted work man-hours and a target man-hour that has been set in advance for the serial number.

[0065] This makes it possible to obtain the work time for each process in association with the serial number and the worker, and by aggregating these, the work results for each serial number and worker can be aggregated. Therefore, the validity of the work results, that is, the aggregated work man-hours, can be guaranteed. Furthermore, since the work results whose validity is guaranteed can be input directly into the system, the validity of the target man-hours can also be appropriately determined.

[0066] In addition, in the work man-hour counting device 1, the work start data creation unit creates work start data when both the serial number and the worker number can be acquired at the same time, or when an input indicating the start of work is received with the serial number and the worker number acquired, and the work end data creation unit creates work end data when at least one of the serial number or the worker number cannot be acquired, or when an input indicating the end of work is received. This makes it possible to reliably determine the start and end of work, and obtain appropriate counting results.

[0067] The work man-hour counting device 1 further includes an interruption processing unit that, when receiving an input to interrupt a task after it has been started, stores the current task content, creates task end data for the current task, and creates new task start data for the task to be performed after the interruption, and a resumption processing unit that, when receiving an input to resume the task after the interruption, creates task end data for the task performed after the interruption, and creates new task start data for the task content stored at the time of interruption. This allows the performance of each task to be properly counted, even if another task becomes necessary during the task.

[0068] In addition, in the work man-hour counting device 1, the serial number acquisition unit can acquire multiple serial numbers, and the man-hour counting unit 32 assigns man-hours to the multiple serial numbers and counts them. This makes it possible to appropriately count man-hours for each serial number when working on multiple parts together from the viewpoint of work efficiency, without placing a burden on the worker to re-register each time.

[0069] The work man-hour counting device 1 further includes a worker management unit 27 that stores worker numbers and the qualifications held by the workers in association with each other, and the worker number acquisition unit checks whether the worker with the acquired worker number has the appropriate qualifications. This makes it possible to prevent work from being performed by a worker who does not have the work qualifications.

[0070] The work man-hour counting device 1 also includes a worker management unit 27 that associates a worker with a worker number, and the worker management unit 27 further associates the worker number with the worker's affiliation, and the man-hour counting unit 32 counts the man-hours for each worker's affiliation. This makes it possible to classify and count the work results in detail, and to appropriately evaluate the work results.

[0071] In addition, the work man-hour counting device 1 includes a nonconformity processing unit 34 that instructs corrective work when the work content is nonconformant. This makes it possible to prevent mistakes such as forgetting work that requires correction, and to grasp the actual time spent as the work performance. In the embodiment of the work man-hour counting device 1, the serial number is coded and written on the instruction sheet that specifies the work content, and in the process of acquiring the serial number, the serial number is acquired by reading the code written on the instruction sheet. This makes it possible to acquire the serial number without placing an excessive burden on the worker.

[0072] Furthermore, the work man-hour counting device 1 of the embodiment includes a linking unit 24 that links the serial number to a serial number tag 25 that stores a unique identification number in advance, and the serial number acquisition unit acquires the serial number linked to the identification number by reading the identification number of the wireless tag for the serial number. This eliminates the need for an RF tag writing device in the work man-hour counting device 1 itself, making it possible to suppress the device from becoming complicated and increasing costs.

[0073] Furthermore, in the work man-hour counting device 1 of the embodiment, the worker number is coded and written on the worker tag 28 carried by the worker, and the worker number acquisition unit acquires the worker number by reading the coded information written on the worker tag 28. This makes it possible to acquire the serial number without placing an excessive burden on the worker. Note that in the case of a configuration in which coded information is read, the worker tag 28 does not necessarily need to be an RF tag, and a card-type tag may be used as appropriate.

[0074] In the work man-hour counting device 1 of the embodiment, the worker number is recorded in the worker tag 28 carried by the worker, and the worker number acquisition unit acquires the worker number by reading the worker tag 28. This makes it possible to acquire the worker number without placing an excessive burden on the worker.

[0075] Various effects similar to those of the above-described work man-hour collection device 1 can be obtained by a work man-hour collection method including a step of acquiring the serial number of the work target, a step of acquiring a worker number assigned to the worker, a step of creating work start data including at least the serial number and the start time of the work when work is started after the serial number and worker number have been acquired, a step of creating work end data including at least the serial number and the end time of the work when the work is ended, a step of collecting work man-hours for each serial number based on the work start data and the work end data, and a step of presenting the collected work man-hours and a target man-hour that is assumed in advance for the serial number.

[0076] In the embodiment, an example has been shown in which the work hour calculation device 1 is configured as a system having a management device 2 and a terminal device 4, but it is also possible to configure the device such that functional blocks are aggregated in the management device 2 and a display terminal having a touch panel is provided in the work space 3. Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
