(Embodiment 1)
Embodiment 1 will be described below with reference to FIGS. 1 to 8. FIG.

FIG. 1 is a configuration diagram showing an example of a work management system 10 according to Embodiment 1. As shown in FIG.

The work management system 10 is a system that manages the work of multiple workers on the production floor. In the following description, the operator is assumed to be a person, but the operator may be a robot (for example, a multi-axis robot or a robot used in a mounting device or the like).

For example, a production floor may be equipped with various equipment, such as mounting or printing equipment, and manage the work of multiple workers on these equipment. The work management system 10 is communicably connected to these facilities provided on the production floor by wire or wirelessly. These facilities transmit error information indicating that an error has occurred to the work management system 10 when an error occurs due to work performed by a worker.

For example, a production floor is equipped with a display, and a worker on the production floor can visually recognize the contents displayed on the display. The display provided on the production floor may be a display of a mobile terminal or the like used by workers on the production floor. The work management system 10 is communicably connected to a display provided on the production floor by wire or wirelessly. The display displays instruction information and guidance information transmitted from the work management system 10 . Instruction information and guidance information will be described later.

For example, a production floor is equipped with a camera to photograph workers' work on the production floor. Specifically, the camera photographs the subject's confirmation work in the first area. The first area and confirmation work will be described later. The camera may be installed on the wall or ceiling of the floor, or may be installed on a workbench where the subject performs confirmation work. Alternatively, the camera may be smart glasses or the like worn by the subject performing the confirmation work. Also, the camera may be a sensor that detects the work of the subject (specifically, detects the work of the subject or the state of the work object), and the cameras in the above and following descriptions are referred to as sensor, and photography may be replaced with detection. The work management system 10 is communicably connected to a camera provided on the production floor by wire or wirelessly. The camera transmits information (specifically, images or videos) obtained by photographing to the work management system 10 .

Here, an example of work performed by the worker will be described.

For example, the operator performs splicing work, parts supply work to the autoload feeder, feeder placement work, soldering work, empty tape box cleaning work, recognition error handling work, adsorption error handling work, and transport error handling. Work such as work is performed on the production floor.

The splicing work is a work for splicing a tape on a new reel to a tape on an old reel, which has been supplied with stored components and which has little left, and continuing to supply components from the old reel using the new reel. Specifically, the operator cuts off the leading end of the tape on the new reel and the trailing end of the tape on the old reel with scissors. Then, the worker brings the tape tip of the new reel and the trailing edge of the tape of the old reel into contact with each other at the above-mentioned break, and affixes the affixing tape to join them together.

The work of supplying components to the auto load feeder is the work of supplying reel tape to the auto load feeder attached to the production apparatus. Specifically, the operator cuts the leading end of the tape on the reel up to the portion where the components are stored. Next, the operator operates a switch for opening the shutter of the tape insertion port of the autoload feeder to open the shutter, and inserts the tape of the reel with the tip cut off into the tape insertion port. Then, when the setting of the tape is completed, the operator operates a switch for starting automatic feeding to start automatic feeding.

The feeder placement work is the work of attaching the tape feeder to the production device. Specifically, the worker attaches the tape feeder to a cart attached to the production apparatus. Then, the worker attaches the reel to the cart on which the tape feeder is attached.

The solder leveling work is a work of stirring solder used in a screen printing device or the like. Since solder is stored in a refrigerator or the like and becomes hard, it is necessary to stir the solder taken out of the refrigerator or the like before use. The operator stirs the solder for about 5-10 minutes, depending on the type of solder, to achieve good softness.

Empty tape box cleaning work is work for cleaning an empty tape box that is attached to a cart that is attached to a production apparatus and stores empty tape that has been emptied after components have been supplied. Specifically, the worker removes the empty tape box in which the empty tape is accumulated from the cart and discards the empty tape to clean the empty tape box. Then, the worker attaches the cleaned empty tape box to the cart.

Recognition error handling work is work performed when a recognition error occurs in a camera provided in a production apparatus. For example, a recognition error occurs when a part photographed by a camera is not in the correct position or orientation in the recognition image, or when the cover glass of the camera is dirty. In such a case, the operator should adjust the position, tilt or setting of the camera, adjust the position or tilt of the nozzle that holds the part, remove dirt from the nozzle, or cover the camera as work to deal with the recognition error. Wipe off the dirt on the glass. In addition, for example, if the setting of the board recognition mark preset in the production equipment is incorrect, or if the board stop position is misaligned, a recognition error (specifically, the recognition mark of the board error) occurs. In such a case, the operator corrects the setting of the recognition mark or adjusts the position of the substrate as work to deal with the recognition error.

The suction error handling work is work to be performed when a nozzle suction error occurs. For example, when a pick-up error occurs, the operator checks whether the setting of the component pick-up position of the nozzle is correct as work to deal with the pick-up error, and corrects the setting if it is not correct. Further, for example, when a suction error occurs, the operator adjusts the setting of the suction speed to an appropriate speed as a work to deal with the suction error.

The board transfer error handling work is a work performed when a board transfer error occurs. For example, a substrate transport error occurs when the belt transporting the substrate or the guide of the transported substrate is dirty. In such a case, the operator cleans the belt or guide as work to deal with the board transfer error. Further, for example, when the board detection sensor of the conveyor is in the detection state even though the board is not detected, a board transfer error occurs. In such a case, the operator checks whether or not the substrate detection sensor is dirty, and wipes off the dirt if it is, as work to deal with the substrate transfer error.

The work management system 10 may be a computer located on the production floor or a computer such as a server located outside the production floor. The work management system 10 may be a device provided in one housing, or may be a system divided into two or more housings and realized by two or more computers. When the work management system 10 is realized by two or more computers, the constituent elements that make up the work management system 10 may be distributed among the two or more computers.

The work management system 10 includes an acquisition unit 11 , a selection unit 12 , an instruction information generation unit 13 , a calculation unit 14 , a guidance information generation unit 15 , a work management database 16 and a worker management database 17 . The work management system 10 is implemented by a computer including a processor, memories such as ROM (Read Only Memory) and RAM (Random Access Memory), and a communication interface. Acquisition unit 11, selection unit 12, instruction information generation unit 13, calculation unit 14, and guidance information generation unit 15 are implemented by a processor operating according to a program stored in a memory. The work management database 16 and the worker management database 17 may be stored in the same memory as the memory in which the programs are stored, or may be stored in separate memories. The work management system 10 communicates with equipment, displays and cameras installed on the production floor via a communication interface.

Acquisition unit 11 acquires the first information. For example, the first information includes error information indicating that an error has occurred in the first equipment provided on the production floor. For example, the error information includes the first equipment ID, the time when the error occurred, and the details of the error when an error occurred in the first equipment. For example, the acquisition unit 11 adds the acquired error information to the worker management database 17 . Also, for example, the first information includes first worker information about a first worker who performed a first work at the first facility. For example, the first worker information includes a first worker ID that identifies the first worker, first work information that indicates the content of the first work, a first equipment ID that identifies the first equipment, and a first equipment ID that identifies the first equipment. This is information that associates the time when the work was performed. For example, the acquisition unit 11 adds the acquired first worker information to the work management database 16 . Further, for example, the acquisition unit 11 acquires work plan information indicating work plans to be performed by each of the plurality of workers.

The selection unit 12 selects a target person from among the plurality of workers based on the first information acquired by the acquisition unit 11 . For example, the selection unit 12 selects the target person by referring to the first worker information. Also, for example, the selection unit 12 selects a target person based on the error information acquired by the acquisition unit 11 and the work management database 16 . Specifically, the selection unit 12 refers to the work management database 16 to determine whether or not the first equipment ID included in the error information is managed by the work management database 16. is managed by the work management database 16, the first worker ID corresponding to the first equipment ID managed by the work management database 16 is identified, and the target person is identified based on the identified first worker ID. Select. In addition, when a plurality of first worker IDs are associated with the first equipment ID in the work management database 16 and managed, the selection unit 12 selects the first worker corresponding to the time closest to the time when the error occurred. The ID may be specified, and the target person may be selected based on the specified first worker ID.

The instruction information generation unit 13 generates instruction information indicating that the target person selected by the selection unit 12 is to perform confirmation work for confirming the accuracy of the work. For example, the instruction information is information that instructs the subject to perform the confirmation work in an area (referred to as a first area) different from the area in which the subject was working on the production floor. The instruction information generation unit 13 is an example of an output unit that outputs the generated instruction information. For example, the instruction information generation unit 13 refers to the work plan information to determine whether or not the selected target person can perform the confirmation work. , to output the instruction information. For example, the instruction information generator 13 outputs the instruction information to a display provided on the production floor for display.

The calculator 14 calculates the accuracy of the confirmation work. For example, the calculation unit 14 may acquire video data of a subject performing confirmation work, analyze the acquired video data, and calculate the accuracy of the confirmation work. Further, for example, the calculation unit 14 may acquire the work time required for the confirmation work by the subject, and calculate the accuracy of the confirmation work based on the acquired work time. Further, for example, the calculation unit 14 associates the calculated accuracy of the confirmation work with the worker ID of the target person, and adds them to the worker management database 17 .

The guidance information generator 15 generates guidance information corresponding to the accuracy calculated by the calculator 14 . The guidance information generator 15 outputs the generated guidance information. For example, the guidance information generator 15 outputs the guidance information to a display provided on the production floor for display.

For example, in the work management database 16, there are a plurality of worker IDs identifying individual workers, a plurality of work information identifying work performed by individual workers, and a plurality of work information identifying work performed by individual workers. A plurality of equipment IDs that identify equipment is associated with the time when each worker performed the work.

For example, in the worker management database 17, a plurality of worker IDs, a plurality of pieces of work information, details of a plurality of errors occurring in a plurality of pieces of equipment, and times when the plurality of errors occurred are associated with each other.

Details of the acquisition unit 11, the selection unit 12, the instruction information generation unit 13, the calculation unit 14, and the guidance information generation unit 15 will be described later with reference to FIGS.

FIG. 2 is a flow chart showing an example of the work management method according to the first embodiment.

FIG. The description of each component included in the work management system 10 described below can be replaced with the description of each process in the work management method.

Next, details of the acquisition unit 11, the selection unit 12, the instruction information generation unit 13, the calculation unit 14, and the guidance information generation unit 15 will be described with reference to FIGS. 3 to 8. FIG.

FIG. 3 is a flowchart showing an example of operation when acquiring worker information according to the first embodiment.

The acquiring unit 11 acquires, as first information, worker information about a plurality of workers who work on the production floor (step S11), and adds the acquired worker information to the work management database 16 (step S12). The worker information is information that associates a worker ID that identifies the worker, work information that indicates the content of the work, an equipment ID that identifies the equipment that the worker is working on, and the time at which the work was performed. is. Since the production floor has multiple workers working on multiple pieces of equipment, the work management database 16 contains worker information about various workers and various pieces of equipment. . An example of the work management database 16 will now be described with reference to FIG.

FIG. 4 is a table showing an example of the work management database 16. As shown in FIG.

The work management database 16 stores a plurality of worker IDs identifying individual workers, a plurality of work information identifying the work performed by each worker, and a plurality of facilities on which each worker performed work. A plurality of equipment IDs to be specified are associated with the work time when each worker performed the work. As shown in FIG. 4, for example, a worker with a worker ID of A001 performs splicing work on a facility with a facility ID of M001 at 9:00, and a worker with a worker ID of A002 performs splicing work on a facility with a facility ID of M001 at 9:00. performed the soldering work on the equipment with the equipment ID M002 at 9:00, and the worker with the worker ID A003 performed the splicing work on the equipment with the equipment ID M003 at 13:00. It is recorded in the database 16.

FIG. 5 is a flowchart showing an example of operation when selecting a worker caused by an error according to the first embodiment. For example, suppose an error has occurred in a first piece of equipment on the production floor.

The acquisition unit 11 acquires error information indicating that an error has occurred in the first equipment (step S21). The error information includes the first equipment ID, the time when the error occurred, and the content of the error when an error occurred in the first equipment.

Next, the selection unit 12 refers to the work management database 16 (step S22). The worker information acquired by the acquiring unit 11 in step S11 includes first worker information related to the first worker who performed the first work in the first equipment. The first worker information includes a first worker ID that identifies the first worker, first work information that indicates the content of the first work, a first equipment ID that identifies the first equipment, and the first work. It is information that associates the time when it was performed. In step S<b>12 , the acquisition unit 11 combines the acquired first worker information with a plurality of worker IDs identifying individual workers, a plurality of work information identifying work performed by each worker, and individual are added to the work management database 16 in which a plurality of facility IDs identifying a plurality of facilities on which the worker has worked and the time at which each worker performed the work are associated with each other. By referring to the first worker information in the work management database 16, the selection unit 12 selects the worker caused by the error (that is, the first worker who performed the first work at the first equipment in which the error occurred). Can be selected as a target person. Specifically, based on the error information acquired by the acquisition unit 11 and the work management database 16, the error information is collated with the work management database, whereby the target person can be selected. In the work management database 16, the worker ID and the equipment ID are associated, and in the work management database 16, the worker with the first worker ID associated with the first equipment ID included in the error information is the first equipment. This is because it is possible to identify the first worker who performed the first work in .

In this way, the selection unit 12 refers to the work management database 16 to determine whether the first equipment ID included in the error information is managed by the work management database 16. , when managed by the work management database 16, identify the first worker ID corresponding to the first equipment ID managed by the work management database 16, and select the target person based on the identified first worker ID do.

Next, the selection unit 12 determines whether a plurality of first worker IDs are associated with the first equipment ID of the first equipment in which the error occurred in the work management database 16 (step S23). ). If a plurality of workers are working in the first equipment, multiple first worker IDs will be associated with the first equipment ID. The processing in step S23 is performed.

When a plurality of first worker IDs are associated with the first equipment ID and managed in the work management database 16 (Yes in step S23), the first worker ID corresponding to the time closest to the time when the error occurred. is specified (step S24), and a target person is selected based on the specified first worker ID. The first worker who was performing the first work at the first facility at the time closest to the time when the error occurred is considered to be the worker most likely to cause the error, so the first worker was selected as the target person. be done.

On the other hand, if a plurality of first worker IDs are not associated with the first equipment ID in the work management database 16 (No in step S23), the first equipment ID associated with the first equipment in which the error occurred A first worker ID is specified (step S25), and a target person is selected based on the specified first worker ID. In this case, since there is only one first worker who was performing the first work in the first facility, the first worker is selected as the target worker.

Next, the acquisition unit 11 adds the acquired error information to the worker management database 17 (step S26). An example of the worker management database 17 will now be described with reference to FIG.

FIG. 6 is a table showing an example of the worker management database 17. As shown in FIG.

In the worker management database 17, a plurality of worker IDs, a plurality of pieces of work information, details of a plurality of errors occurring in a plurality of pieces of equipment, and times when the plurality of errors occurred are associated with each other. As shown in FIG. 6, for example, it is recorded that an operator with an operator ID of A001 spliced a paper carrier tape and caused one adsorption error between 9:00 and 10:00. . Further, for example, it is recorded that an operator with an operator ID of A002 spliced an embossed carrier tape and caused five top tape breakage errors between 10:00 and 11:00. Further, for example, it is recorded that the worker with the worker ID A003 performed the tray component replacement work and caused three suction errors between 11:00 and 12:00. For example, when error information is added to the worker management database 17, the number of occurrences of corresponding errors is updated. For example, such a worker management database 17 may be used when selecting a subject in Embodiment 2, which will be described later. Specifically, the worker management database 17 may be referred to, and a worker with a large number of error occurrences may be selected as a target worker.

Returning to the description of FIG. 5, the instruction information generation unit 13 generates instruction information indicating that the target person selected by the selection unit 12 is to perform confirmation work for confirming the accuracy of the work (step S27). . For example, the instruction information is information indicating that the subject is to perform the confirmation work in the first area of the production floor. An example of the first area will now be described with reference to FIG.

FIG. 7 is a diagram showing an example of the first area.

The first area is, for example, an area different from the area where the subject was performing the first work on the first equipment, and is a predetermined dedicated area within the production floor for performing the confirmation work. . In the first area, a plurality of cameras are provided so as to surround the working place of the subject so that the situation of the confirmation work by the subject can be photographed in detail. As shown in FIG. 7, for example, an upper camera, a front camera, and a side camera capture images of the confirmation work of the subject. This makes it possible to confirm the accuracy of the confirmation work by the subject. Note that the confirmation work performed by the subject in the first area may be the same as or different from the first work performed by the subject on the first facility. For example, the confirmation work may be work in which the subject makes many errors.

Returning to the description of FIG. 5, the instruction information generator 13 outputs the generated instruction information (step S28). For example, the instruction information generator 13 outputs instruction information to a display provided on the production floor. As a result, the subject who has confirmed the display can perform the confirmation work.

In some cases, the subject cannot interrupt the work in progress and cannot perform the confirmation work. Therefore, for example, in step S11 or the like, the acquisition unit 11 may acquire work plan information indicating a work plan to be performed by each of a plurality of workers. Then, the instruction information generating unit 13 refers to the work plan information to determine whether or not the selected target person can perform the confirmation work. , may output instruction information. Since the work plan information also includes the work plan of the subject, it can be determined whether or not the selected subject can perform the confirmation work.

In addition, in the case where multiple workers can perform confirmation work simultaneously in the first area, when multiple errors occur at the same time, the workers caused by each error are selected as target workers, and at the same time Instruction information for each subject may be generated and output. On the other hand, when a plurality of workers cannot perform confirmation work at the same time in the first area, for example, in step S11 or the like, the acquisition unit 11 obtains work plans to be performed by each of the plurality of workers. You may acquire the work plan information shown. Then, when a plurality of errors occur at the same time and a worker caused by each error is selected as a target worker, the instruction information generation unit 13 refers to the work plan information to generate the selected target worker. may determine the start time at which to begin checking operations in the first area. For example, the instruction information generation unit 13 may refer to work plan information to determine the start time of a worker who has a vacancy earlier. Alternatively, the instruction information generation unit 13 may refer to the worker management database 17 to determine the start time of a worker with a large number of errors to be earlier. Then, the instruction information generation unit 13 generates and outputs instruction information including the start time of the confirmation work in the first area for each selected target person. Accordingly, each subject can prevent a plurality of workers from simultaneously performing the confirmation work in the first area by starting the confirmation work at the start time indicated by the instruction information.

FIG. 8 is a flowchart showing an example of the operation when calculating the accuracy of confirmation work according to the first embodiment.

After or while the subject performs the confirmation work according to the output instruction information, the calculation unit 14 acquires information for calculating the accuracy of the confirmation work performed by the subject (step S31). For example, the calculation unit 14 acquires video data obtained by photographing a subject performing confirmation work. Further, for example, the calculation unit 14 acquires the work time required for the confirmation work by the subject.

Next, the calculation unit 14 determines whether or not the accuracy of the confirmation work can be calculated (step S32). Situations in which it is not possible to calculate the accuracy of the confirmation work or situations in which it is difficult to It is a situation where the hand cannot be photographed).

If the accuracy of the confirmation work cannot be calculated (No in step S32), the calculation unit 14 generates and outputs warning information indicating a warning to the subject (for example, an instruction to prompt the subject to change the standing position or posture). (step S33). Then, the processing from step S31 is performed again. As a result, the subject can change the standing position or posture, and the confirmation work performed by the subject can be correctly photographed.

If the accuracy of the confirmation work can be calculated (Yes in step S32), the calculator 14 calculates the accuracy of the confirmation work (step S34). For example, the calculation unit 14 may analyze the acquired video data and calculate the accuracy of the confirmation work. Specifically, it extracts feature points from the colors of the work objects shown in the video, recognizes the work objects, identifies the work process from its movement information, etc., and compares it with the video when the work is done properly. By comparison, the accuracy of the verification work can be calculated. Note that when calculating the accuracy of the confirmation work, a machine-learned model or the like may be used, or the judgment result of the confirmation work by a person may be used. Alternatively, the calculation unit 14 may calculate the accuracy of the confirmation work based on the work time required for the confirmation work by the subject. For example, it may be calculated that the accuracy of the confirmation work is high when the confirmation work is completed within a predetermined time. Further, for example, when the confirmation work is divided into a plurality of processes, it may be calculated that the accuracy of the confirmation work is high when each process is completed within a predetermined time. In other words, if there is even one process that could not be completed within the predetermined time, it may be calculated that the accuracy of the confirmation work is low. Accuracy may be expressed numerically or the like.

Next, the calculation unit 14 associates the calculated accuracy information indicating the accuracy of the confirmation work with the worker ID of the target person, and adds them to the worker management database 17 (step S35). For example, the worker management database 17 to which the accuracy information of the subject is added may be used when selecting the subject in the second embodiment described later. Specifically, the worker management database 17 may be referred to and a worker with low accuracy may be selected as the target.

Next, the guidance information generator 15 generates guidance information corresponding to the accuracy calculated by the calculator 14 (step S36). Guidance information includes, for example, information indicating the accuracy of confirmation work. Also, the guidance information includes, for example, educational information according to the accuracy of the confirmation work. For example, when the accuracy is low, the guidance information includes educational information for performing educational training or OJT (On the Job Training).

Then, the guidance information generator 15 outputs the generated guidance information (step S37). The guidance information generator 15 outputs guidance information to a display provided on the production floor. As a result, the subject who has confirmed the display can confirm the accuracy of the confirmation work that he or she has performed, and confirm that it is necessary to conduct education and training or OJT.

As described above, in Embodiment 1, when an error occurs in the first equipment provided on the production floor, the first worker related to the error is selected as the target person, and the selected target person confirmation work to confirm the accuracy of the work. The confirmation work is, for example, a predetermined work, and all that is required is to prepare a camera or the like for photographing the confirmation work of the subject, and there is no need for a large number of cameras or an omnidirectional camera. In addition, the processing for analyzing captured data for determining accuracy can be less complicated than data captured by an omnidirectional camera or the like. Therefore, it is possible to easily check the accuracy of the worker's work.

(Embodiment 2)
Next, Embodiment 2 will be described.

In Embodiment 1, an example was described in which a target person is selected when an error occurs in the first facility provided on the production floor. Embodiment 2 describes an example in which a target person is selected at a predetermined timing. The predetermined timing may be a predetermined timing within a day (for example, timing after the end of lunch break) or may be timing every few hours (for example, every 3 hours). .

The second embodiment will be described using the same reference numerals as those of the work management system 10 in the first embodiment, and will focus on the differences from the first embodiment. Also in the second embodiment, the target person may be selected when an error occurs in the first facility provided on the production floor. That is, the work management system 10 may have both a function of selecting a target person at a predetermined timing and a function of selecting a target person when an error occurs in the first equipment. Alternatively, in Embodiment 2, even if an error occurs in the first facility provided on the production floor, the subject may not be selected.

The acquisition unit 11 acquires worker information about a plurality of workers. For example, the worker information is a worker management database that associates and manages a plurality of pieces of accuracy information indicating the accuracy of work performed by each of a plurality of workers and a plurality of worker IDs that indicate the IDs of each of the plurality of workers. 17 is managed. Further, for example, the acquisition unit 11 acquires work plan information indicating work plans to be performed by each of the plurality of workers.

For example, the selection unit 12 selects a target person based on a worker ID with low accuracy among a plurality of worker IDs managed by the worker management database 17 . Alternatively, for example, the selection unit 12 randomly selects a target person from a plurality of workers managed by the worker management database 17 .

The operation when acquiring the worker information and the operation when calculating the accuracy of the confirmation work according to the second embodiment are basically the same as those in the first embodiment, so the description is omitted. Here, the operation at the time of worker selection will be mainly described with reference to FIG.

FIG. 9 is a flow chart showing an example of operations when selecting a worker according to the second embodiment.

First, the selection unit 12 determines whether or not a predetermined timing has arrived (step S41). If the predetermined timing has not arrived (No in step S41), the selection unit 12 repeats the processing in step S41 until the predetermined timing arrives.

When a predetermined timing has arrived (Yes in step S41), the selection unit 12 collects a plurality of pieces of accuracy information indicating the accuracy of the work of each of the plurality of workers and a plurality of pieces of work indicating the ID of each of the plurality of workers. Reference is made to the worker management database 17 that manages the worker ID in association with the worker ID (step S42). For example, in the worker management database 17, the accuracy of work performed by workers is managed using numerical values as accuracy information.

Next, the selection unit 12 identifies one worker ID from among a plurality of worker IDs included in the worker management database 17 (step S43). For example, the selection unit 12 identifies a worker ID with low accuracy among a plurality of worker IDs managed by the worker management database 17, and selects a target worker based on the worker ID. As a result, it is possible to select a worker whose work is performed with low accuracy as a target person to perform the confirmation work. Alternatively, the selection unit 12 may randomly select a target person from a plurality of workers managed by the worker management database 17 . In this case, it is possible to prevent the continued selection of workers whose work accuracy is low.

Next, the acquisition unit 11 acquires the work plan information (step S44), and the selection unit 12 refers to the work plan information to determine whether the selected target person can perform the confirmation work ( step S45). Since the work plan information includes the work plans scheduled to be carried out by each of a plurality of workers working on the production floor, it is possible to determine whether or not the selected target person can carry out the confirmation work. . If the selected subject cannot perform the confirmation work (No in step S45), the process from step S42 is performed again to select another worker as the subject.

If the selected subject can perform the confirmation work (Yes in step S45), the instruction information generation unit 13 causes the subject selected by the selection unit 12 to perform the confirmation work for confirming the accuracy of the work. Instruction information indicating that is generated (step S46), and the generated instruction information is output (step S47). Thereby, the selected subject can perform the confirmation work.

As described above, in the second embodiment, the target person is selected at a predetermined timing, and the selected target person can be made to perform the confirmation work for confirming the accuracy of the work. The confirmation work is, for example, a predetermined work, and all that is required is to prepare a camera or the like for photographing the confirmation work of the subject, and there is no need for a large number of cameras or an omnidirectional camera. In addition, the processing for analyzing captured data for determining accuracy can be less complicated than data captured by an omnidirectional camera or the like. Therefore, it is possible to easily check the accuracy of the worker's work.
