Mode for Carrying Out the Invention

[0011] Hereinafter, an embodiment of the present disclosure will be described while referring to the drawings. FIG. 1 is a diagram showing an example of the configuration of the work management system.

[0012] The work management system performs processes for managing the work on the work object. The work object may be a product, a semi-finished product (product in the manufacturing process), or a raw material. Further, the work to be managed only needs to include work performed by a worker on the work object, and the appearance of the work object can change before and after the work. For example, the work may include work for processing raw materials or semi-finished products, work for assembling semi-finished products (parts), work for packing products, or work for inspecting products. Also, the work may be, for example, work at a production site such as a factory, or work at a logistics site. Further, the work to be managed may be regarded as one work for each process in a series of multiple processes, or work in one process (that is, work for each individual process among the multiple processes). When the work to be managed is completed in one process, the work to be managed is the work in that process.

[0013] As described above, the objects of work and the work itself are not limited, but in this embodiment, we will illustrate the case where the work under management includes the packaging of hot-rolled coils manufactured in the steel industry. Therefore, Figure 1 shows an example of packaging equipment for performing work including the packaging of hot-rolled coils, along with the work management system. Hot-rolled coils are manufactured, for example, by winding hot-rolled steel strips produced in a hot-rolling line into coils. In a hot-rolling line, for example, the following are performed: heating the slab (steel material), rough-rolling the heated slab, continuously rolling the rough bar (roughly rolled slab) in a tandem rolling mill, cooling the hot-rolled steel strips after continuous rolling, and winding the cooled hot-rolled steel strips into coils. In addition, for example, hot-rolled coils may be unwound and pickled, and the hot-rolled coils may be wound into coils again after pickling. In the following description, hot-rolled coils will be abbreviated as coils as needed.

[0014] <Work Equipment> Figure 1 illustrates a case where the packaging equipment includes a belt conveyor 111, a packaging device 112, and a strapping machine 113. The belt conveyor 111 transports the coil C. Figure 1 illustrates a case where operations including packaging are performed on the coil C being transported by the belt conveyor 111. Figure 1 illustrates a case where the coil C moves in the direction of the white arrows shown on both sides of the belt conveyor 111. Note that the transport of the coil C by the belt conveyor 111 may be temporarily stopped. Also, the coil C may be temporarily transported in the opposite direction to the white arrows.

[0015] Furthermore, Figure 1 illustrates a case where the area of ​​the belt conveyor 111 is divided into 12 regions in the direction of conveying coil C, and a predetermined task is performed in each of the 12 regions (see the numbers shown below the belt conveyor 111 in Figure 1). In the following explanation, these 12 regions will be referred to as positions (positions 1, 2, ..., 12) as needed. Note that some of these 12 positions 1 to 12 may be positions where no work is performed. Also, some of these 12 positions 1 to 12 may be positions where the appearance of coil C does not change before and after the work is performed. An example of such work is the work of checking the appearance of coil C. Furthermore, Figure 1 illustrates a case where coil C is present in all positions 1 to 12, but there may be time periods when coil C is not present in each position 1 to 12. Also, in Figure 1, for the sake of notation, only one coil is labeled (C).

[0016] The packaging device 112 is a device for wrapping packaging material around the surface of the coil C. The packaging material may be made of paper or metal. The packaging equipment may also include multiple packaging devices. The strapping machine 113 is a device for strapping the coil C with strapping bands. The packaging equipment may also include multiple strapping machines. The packaging device 112 and the strapping machine 113 themselves are implemented using known technology, so a detailed explanation of them is omitted here.

[0017] Workers W1 to W2 who work in the packaging equipment perform the tasks assigned to their respective positions 1 to 12. In the following description, workers who work in the packaging equipment will be referred to as field workers as needed. The tasks performed by field workers will be referred to as field work as needed. Field work may include, for example, attaching at least one of the following to coil C: protective material, stickers, labels, and colored tape. The protective material is attached to coil C to protect it. Field work may also include, for example, field workers W1 to W2 attaching coil C with cable ties to coil C that cannot be attached by the binding machine 113. Field work may also include, for example, painting or lubricating coil C. Field work may also include, for example, attaching inspection labels to coil C. In the following description, materials used in field work will be collectively referred to as packaging materials as needed.

[0018] The specific details of the work performed in each position 1-12 are not limited to those described here, as they can be determined according to the configuration of the packaging equipment and the operating policies of the steelworks (hot rolling mill), etc. Therefore, a detailed explanation is omitted here. Also, the packaging equipment itself may be existing packaging equipment at the steelworks (hot rolling mill), for example, and is not limited to the packaging equipment exemplified in Figure 1.

[0019] On-site work is carried out according to the packaging specifications. The packaging specifications include information indicating how the work at the packaging equipment should be performed. For example, the packaging specifications include the type, number, and location of the packaging materials to be used. As mentioned above, there are various types of packaging materials, and the location and number of packaging materials used also vary. Therefore, the packaging specifications also vary. Thus, in addition to supporting the work at the packaging equipment, there is a need for a technology that can easily and reliably verify after the fact whether the on-site work was performed according to the packaging specifications. If it is confirmed that the on-site work was not performed according to the packaging specifications before the product is shipped, for example, it is possible to prevent the shipment of coil C that has not been worked on at the packaging equipment according to the packaging specifications. Also, if it is confirmed that the on-site work was not performed according to the packaging specifications after the product has been shipped, for example, it is possible to determine whether the cause of the packaging not being performed according to the packaging specifications lies in the work at the packaging equipment or in other work (e.g., transportation). The work management system of this embodiment is intended to solve at least some of the problems exemplified above. Furthermore, the technology to easily and reliably verify after the fact whether or not on-site work was performed according to specifications is a technology that is also required for work other than that performed in packaging equipment. As mentioned above, the work is not limited to work performed in packaging equipment, and the work management system of this embodiment, as exemplified below, can also be applied to work other than that performed in packaging equipment.

[0020] <Overview of the work management system> Here, an example of the outline of the work management system of this embodiment will be described. The work management system of this embodiment displays work guideline images and work performance images on a display device. A work guide image is an image of the work object used as a guide for the work. In this embodiment, the work guide image is an image of coil C used as a guide for work in the packaging equipment. As mentioned above, work in the packaging equipment is performed according to the packaging specifications. By referring to the work guide image, on-site workers W1 and W2 can more easily understand the content of the work in the packaging equipment (packaging specifications) compared to referring to text information. Therefore, for example, it is possible to improve work efficiency and reduce work errors.

[0021] Work performance images are photographs taken of the object after work has been performed, and can be used as proof of work performed on the object. The work guideline images and work performance images include images of the work object after the work has been performed. The work object after the work has been performed is not limited to the work object after all the work to be performed on it has been completed, but may also include the work object after intermediate work has been performed before all the work to be performed on it has been completed.

[0022] In this embodiment, the work guide image and the work performance image include an image of coil C after the packaging work is completed. The image of coil C after the packaging work may include an image of coil C after all work in the packaging equipment has been completed. Alternatively, the image of coil C after the packaging work may include an image of coil C after intermediate work has been completed before all work in the packaging equipment has been completed. For example, it may include an image of coil C after work has been completed at a predetermined position among positions 1 to 11, or it may include an image of the work object after some of the work performed at each position 1 to 12 has been completed.

[0023] By displaying images of work results and work guidelines on a display device, for example, on-site workers W1 to W2 can compare these images. Therefore, on-site workers W1 to W2 can easily confirm retrospectively whether or not the work was performed according to the specifications.

[0024] Here, the work guide image may include images of the work object after each individual task in multiple processes. For example, the work guide image may include a work guide image after the first task, which is an image of the work object after the first task, and a work guide image after the second task, which is an image of the work object after the second task, which is performed after the first task. In this case, the first and second tasks may be performed at different positions. Alternatively, the first and second tasks may be performed at the same position. In this case, the work guide image after the first task may be an image of the work object after some of the tasks performed at each position 1 to 12 have been completed, and the work guide image after the second task may be an image of the work object after the remaining tasks performed at each position 1 to 12 have been completed.

[0025] In this embodiment, for the sake of simplicity, the work before the packaging operation is defined as the work up to the moment immediately before the packaging material is attached to the coil C, and the packaging operation is defined as the work performed in the packaging equipment from the moment the packaging material is attached to the coil C onward. In this case, the work up to the moment immediately before the packaging material is attached to the coil C is an example of the first operation, and the work from the moment the packaging material is attached to the coil C onward is an example of the second operation.

[0026] On-site workers W1 and W2 can refer to work guide images of the work object after each of the first and second tasks, thereby improving work efficiency. In this case, the work management system of this embodiment may switch between displaying the work guide image after the first task and the work guide image after the second task. The switching display may be performed within the same display frame. Alternatively, the information to be switched may be displayed in separate display frames, and the switching display may be performed by switching which of these display frames is displayed in the foreground. Note that the display frame may be a so-called window.

[0027] By switching between displaying the work guideline images after the first and second tasks, the display space for these images can be increased while allowing field workers W1 and W2 to refer to the work guideline images after each task. However, this is not always necessary. For example, the work management system may display the work guideline images after the first and second tasks simultaneously in the same display frame. Furthermore, information that can be displayed by scrolling the display frame may also be displayed in the same display frame.

[0028] Furthermore, the work guide image may include at least one of the following: a 3D work guide image and a photographic work guide image. The 3D work guide image is a 3D image based on a three-dimensional model of the work object. In other words, the 3D work guide image is a 3D image based on a three-dimensional model that represents the result of the work performed on the work object. Specifically, an example of a 3D work guide image is a 3D image of coil C showing the position where the label should be attached. The work management system may create the 3D work guide image using, for example, known 3D computer graphics techniques. The photographic work guide image is a photograph of the work object. In other words, the photographic work guide image is a photograph of the result of the work performed on the work object. Specifically, an example of a photographic work guide image is a photograph of coil C in a sample state after the work is completed.

[0029] Depending on the nature of the work, a 3D image of the work guide may be easier to represent than a photographic image of the work guide, or conversely, a photographic image may be easier to represent than a photographic image of the work guide. Of the 3D image of the work guide and the photographic image of the work guide, the image that best represents the work object after the work is completed may be used. For example, when representing coil C, which has undergone packaging work, with a 3D image (computer graphics), it may not be easy to clearly show the worker iron packaging resources (cable ties) that have a similar color to coil C. On the other hand, it may not be easy to prepare photographic images of the work guide that correspond to all packaging specifications. Furthermore, using a 3D image allows for viewing coil C and packaging resources from various angles. Note that the angle of the 3D image of the work guide may be changed automatically in the work management system or manually by on-site workers.

[0030] The work guide images may include both 3D work guide images and photographic work guide images. This allows, for example, on-site workers to select the work guide images they need during on-site work. In this case, the work management system may switch between displaying the 3D work guide images and photographic work guide images. This allows for a larger display space for both the 3D work guide images and photographic work guide images. However, this is not always necessary. For example, the work management system may display both the 3D work guide images and photographic work guide images simultaneously in the same display frame. In other words, the work management system may simultaneously display the work guide image as the work guide image after the first work, and the 3D work guide image as the work guide image after the second work, in the same display frame.

[0031] In addition, the work management system may display work confirmation input information on the display device to allow workers to input that they have performed a post-work check, in order to promote at least one of the following: improved work efficiency, reduced work errors, and easier post-work verification of whether the work was performed according to specifications. In this case, the work management system may display the work guideline image and the work confirmation input information in the same display frame. However, this is not necessarily required, and for example, the work management system may display the work guideline image and the work confirmation input information in separate display frames. Furthermore, the work confirmation input information may also be information for field workers W1 to W2 to input that they have performed a post-work check for each of the multiple verification items. In this way, a more detailed post-work check of whether the work was performed according to specifications can be performed.

[0032] Furthermore, if the work management system has met predetermined work confirmation conditions but has not yet confirmed that the work has been performed, it may output work prompting information to prompt the field workers W1 to W2 to perform the work. This allows the field workers W1 to W2 to perform the work based on the work prompting information. The work management system may display the work prompting information on a display device. In this case, the work prompting information may be text information or other information. For example, in addition to or instead of displaying text information, the work prompting information may be displayed by changing the color of a predetermined area on the screen. The work management system may also output the work prompting information as sound information. The predetermined work confirmation conditions may be, for example, that all work on the work object has been completed. For example, the predetermined work confirmation conditions may be that the work at position 12 has been completed and the product (coil C) has been transported from position 12. Alternatively, the predetermined work confirmation conditions may be that a predetermined work prior to the last work on the work object has been completed (that the next work after the predetermined work can be started). Furthermore, the specified work confirmation conditions may be, for example, the condition that a specified amount of time has elapsed since the completion of each task.

[0033] <Work Management System> The configuration example of the work management system of this embodiment will be described below with reference to Figure 1 and other figures. In Figure 1, this embodiment illustrates a case where the work management system comprises a camera 121a to 121d, a communication device 122a to 122b, a work management device 123, a field work terminal device 124a to 124b, and a work instruction work terminal device 125.

[0034] The imaging devices 121a to 121d are examples of imaging devices that capture images of work results. In this embodiment, imaging devices 121a to 121d are imaging devices that capture images of work results before work in the packaging equipment begins, and imaging devices 121c to 121d are imaging devices that capture images of work results after work in the packaging equipment that changes the appearance of coil C has been completed. Specifically, imaging devices 121a and 121b capture images of the work results of coil C at position 1 from the front and rear sides, respectively. Imaging devices 121c and 121d capture images of the work results of coil C at position 11 from the front and rear sides, respectively. The front side is the downstream side in the conveying direction, and the rear side is the upstream side in the conveying direction.

[0035] In this embodiment, the case in which the imaging devices 121a to 121d capture color moving images is illustrated. However, the imaging devices 121a to 121d do not have to capture color moving images. For example, the imaging devices 121a to 121d may capture grayscale moving images, or color or grayscale still images. Furthermore, depending on the imaging environment of the imaging devices 121a to 121d, the work management system may be equipped with an illumination device that illuminates the area including the imaging area of ​​the imaging devices 121a to 121d.

[0036] Communication devices 122a and 122b each transmit captured data, including work performance images, captured by the imaging devices 121a-121b and 121c-121d, to the work management device 123. As described above, this embodiment exemplifies the case where imaging devices 121a-121d capture moving images. In this case, communication devices 122a-122b may, for example, transmit captured data including a frame image to the work management device 123 each time an image frame is obtained by imaging devices 121a-121d. Alternatively, communication devices 122a-122b may, for example, transmit captured data including multiple frame images to the work management device 123 each time multiple images are obtained by imaging devices 121a-121d. Furthermore, communication devices 122a-122b may transmit captured data to the work management device 123 in response to a request from the work management device 123.

[0037] In this embodiment, we illustrate a case where communication devices 122a and 122b communicate via wired connections with imaging devices 121a-121b and 121c-121d, respectively, and communicate wirelessly with the work management device 123. However, this is not necessarily required. For example, communication devices 122a and 122b may communicate wirelessly with imaging devices 121a-121b and 121c-121d, respectively, or they may communicate via a network. Similarly, communication devices 122a-122b may communicate via wired connections with the work management device 123, or they may communicate via a network. Furthermore, imaging devices 121a-12d may also have the functions of communication devices 122a-122b (functions for transmitting imaging data).

[0038] The field work terminal devices 124a to 124b are terminal devices operated by field workers W1 to W2. As will be described in detail later, in this embodiment, we will illustrate the case in which the work management screen (display frame) that displays the aforementioned work guideline image is displayed by the field work terminal devices 124a to 124b.

[0039] Furthermore, in this embodiment, the case in which the field work terminal devices 124a to 124b are portable terminal devices (for example, tablet terminals) is illustrated. However, the field work terminal devices 124a to 124b do not have to be portable terminal devices. Also, in this embodiment, the case in which the field work terminal devices 124a to 124b have the function of an imaging device is illustrated. For example, if there is a part of the coil C that is the target of packaging work that requires confirmation of quality, the field workers W1 to W2 use the field work terminal devices 124a to 124b (or the imaging device they have) to take an image of the area including that part. In the following description, this image will be referred to as a terminal image as needed. In other words, the terminal images are images taken by the on-site work terminal devices 124a to 124b (or their imaging devices) at the instruction of on-site workers W1 to W2 during work. Therefore, they can capture fine details of the coil C, such as coil C in the process of being worked on, which cannot be captured by work record images, and allow for the determination of quality, etc. In this embodiment, the case in which the terminal images are color still images is given as an example. However, the terminal images are not limited to color still images. For example, the terminal images may be grayscale still images, or color or grayscale moving images. If the device does not have the function of an imaging device, the on-site work terminal device may, for example, acquire images taken by on-site workers W1 to W2 using their own imaging devices (not shown).

[0040] Furthermore, this embodiment illustrates a case where the field work terminals 124a to 124b have the function of a communication device. Specifically, this embodiment illustrates a case where the field work terminals 124a to 124b communicate wirelessly with the work management device 123. However, this is not necessarily required. For example, the field work terminals 124a to 124b may communicate with the work management device 123 via wired communication or via a network. If the field work terminals do not have the function of a communication device, they may communicate with external devices, for example, via a communication device connected to them.

[0041] The work instruction terminal device 125 is a terminal device operated by an operator who gives work instructions to on-site workers W1 to W2. In the following description, this operator will be referred to as the work instructioner as needed. The work instruction terminal device 125 is, for example, a terminal device located in the office of the work site. As will be described in detail later, in this embodiment, we will illustrate a case in which the work management screen displayed on the on-site work terminal devices 124a to 124b is also displayed on the work instruction terminal device 125.

[0042] The work instruction terminal device 125 may be a portable terminal device or a stationary terminal device. In this embodiment, an example is given where the work instruction terminal device 125 has the function of a communication device. Specifically, in this embodiment, an example is given where the work instruction terminal device 125 communicates with the work management device 123 via a wired network. However, this is not necessarily required. For example, the work instruction terminal device 125 may communicate with the work management device 123 via wireless communication. If the work instruction terminal device does not have the function of a communication device, it may communicate with an external device, for example, via a communication device connected to the work instruction terminal device.

[0043] The work management device 123 creates the information necessary for displaying the aforementioned work management screen and transmits this information to the field work terminals 124a to 124b and the work instruction terminal 125. In the following description, this information will be referred to as work management screen information as needed. In this embodiment, we will illustrate a case where the work management device 123 acquires a 3D work guide image and a captured work guide image as work guide images when creating the work management screen information. In addition, in this embodiment, the work management device 123 creates the information necessary for displaying the work performance display screen (display frame), which is a screen switched from the work management screen and displays the aforementioned work performance images, and transmits this information to the field work terminals 124a to 124b and the work instruction terminal 125. In the following description, this information will be referred to as work performance display screen information as needed. In this embodiment, we will illustrate a case where the work management device 123 acquires a work performance image when creating the work performance display screen information.

[0044] Furthermore, this embodiment illustrates a case where the work management device 123 has the function of a communication device. Also, as mentioned above, this embodiment illustrates a case where the work management device 123 communicates with communication devices 122a to 122b, field work terminal devices 124a to 124b, and work instruction work terminal device 125. If the work management device does not have the function of a communication device, it may communicate with an external device, for example, via a communication device connected to the work management device. An example is given where work performance images captured by the shooting devices 121a to 121d are acquired when creating work management screen information.

[0045] <<Work management screen and work performance display screen>> Here, we will explain an example of the work management screen and the work performance display screen. Figure 2A shows an example of the work management screen 200. Figure 2A illustrates a case where the work management screen 200 displays the following: product information display field 201, work guideline image display field 202, material information display field 203, precautions display field 204, work confirmation input information display field 205, terminal captured image display field 206, memo input field 207, field work comment input field 208, work instruction comment input field 209, alarm display field 210, email notification button 211, action input notification button 212, and work performance image display instruction button 213.

[0046] Furthermore, Figure 2A illustrates the case where the work management screen 200 is a GUI (Graphical User Interface). Note that, for the sake of notation, Figure 2A shows all the information displayed on the work management screen 200. However, not all the information displayed on the work management screen 200 has to be displayed simultaneously. For example, a scroll bar (not shown) may be displayed on the work management screen 200. The information displayed on the work management screen 200 may be scrolled by operating the scroll bar. In this case, the information within the work management screen 200 shown in Figure 2A is information within a single display frame (single window).

[0047] Furthermore, in this embodiment, for the sake of simplicity, we will illustrate a case where common information is displayed in the product information display area 201, the work guideline image display area 202, the material information display area 203, the precautions display area 204, and the work confirmation input information display area 205, regardless of position 1 to 12. However, this is not necessarily required. For example, the information displayed in the work guideline image display area 202, the material information display area 203, the precautions display area 204, and the work confirmation input information display area 205 may be created separately for each position 1 to 12.

[0048] Furthermore, in this embodiment, we illustrate a case where the information displayed in the terminal image display field 206, memo input field 207, field work comment input field 208, and work instruction comment input field 209 is created for each of positions 1 to 12.

[0049] For example, the field work terminal devices 124a to 124b may transmit position identification information entered based on the input operations of the field worker to the field work terminal device to the work management device 123, and the work management device 123 may determine the position where the field work terminal device is located based on the position identification information. Alternatively, for example, the work management device 123 may acquire the position information of the field work terminal devices 124a to 124b by using GNSS (Global Navigation Satellite System) or the like, and determine the position where the field work terminal device is located based on the position information. Furthermore, one field work terminal device may be placed for each position, and the work management device 123 may determine the position where the field work terminal device is located based on the identification information of the field work terminal device included in the information transmitted from the field work terminal device to the work management device 123.

[0050] In Figure 2A, the product information display area 201 displays product information, which is information about the workpiece (coil C). Figure 2A illustrates a case where the product information includes a product ID, packaging specification code, and product size. The packaging specification code is identification information for the packaging specification. The packaging specification is linked to the packaging specification code. As mentioned above, the packaging specification includes information that shows how the work performed by the packaging equipment will be carried out. For example, the packaging specification includes packaging material information. The packaging material information is information that shows the packaging materials to be used, and for example, it includes the name of the packaging material to be used, the number to be used, and the location to be used. In this embodiment, an example is shown where the packaging specification further includes work confirmation input information and information indicating precautions. The precautions are information that indicates matters that on-site workers W1 to W2 should pay attention to when performing work in packaging. The precautions are predetermined based on, for example, the requirements from the customer of coil C.

[0051] The work guide image display area 202 displays the work guide image. Figure 2A illustrates a case where the pre-work button 202a, post-work button 202b, and image switching button 202c are displayed in the work guide image display area 202. As mentioned above, this embodiment illustrates a case where the work guide image includes a 3D work guide image and a photographic work guide image. Furthermore, this embodiment illustrates a case where the 3D work guide image and the photographic work guide image each include an image after the first work and an image after the second work. As mentioned above, in this embodiment, the first work is the work up to the work immediately before the packaging material is attached to the coil C, and the second work is the work from the work onward after the packaging material is attached to the coil C. In the following description, the work from the work onward after the packaging material is attached to the coil C will be referred to as the packaging work as needed.

[0052] The pre-work button 202a is pressed by the field worker to display the work guideline image after the first work. The post-work button 202b is pressed by the field worker to display the work guideline image after the second work. The image switching button 202c is pressed by the field worker to switch the display of the work guideline image shown in the work guideline image display field 202 from the 3D work guideline image to the photographed work guideline image, or from the photographed work guideline image to the 3D work guideline image.

[0053] Figure 3 shows an example of a 3D image of the work guideline. Figure 3(a) shows an example of a 3D image of the work guideline for work before packaging, and Figure 3(b) shows an example of a 3D image of the work guideline for work after packaging. Figure 4 shows an example of a captured image of the work guideline. Figure 4(a) shows an example of a captured image of the work guideline for work before packaging, and Figure 4(b) shows an example of a captured image of the work guideline for work after packaging. Here, we illustrate the case where the work after packaging ends at position 11, and the coil C at position 11 is the object to be worked on after packaging. In the following explanation, the work guideline image (3D image of the work guideline, captured image of the work guideline) for work before packaging will be referred to as the work guideline image (3D image of the work guideline, captured image of the work guideline) as needed. Also, in the following explanation, the work guideline image (3D image of the work guideline, captured image of the work guideline) for work after packaging will be referred to as the work guideline image (3D image of the work guideline, captured image of the work guideline) as needed.

[0054] Furthermore, in this embodiment, an example is given in which a 3D image of work guidelines is used to present guidelines to on-site workers W1 to W2 for work performed in the packaging equipment that uses packaging resources other than iron packaging resources (see Figure 3(b)). Furthermore, in this embodiment, as shown in Figure 4, an example is given in which a captured image of work guidelines is used to present guidelines to on-site workers W1 to W2 for work performed in the packaging equipment that uses iron packaging resources (see Figure 4(b)).

[0055] Figure 2A illustrates the case where the 3D image of the work guidelines after the packaging work, as illustrated in Figure 3(b), is displayed. When the pre-work button 202a is pressed in the state illustrated in Figure 3(b), the 3D image of the work guidelines before the packaging work shown in Figure 3(a) is displayed in the work guidelines image display area 202. Also, when the image switching button 202c is pressed in the state illustrated in Figure 3(b), the image of the work guidelines after the packaging work, as shown in Figure 4(b), is displayed in the work guidelines image display area 202. For example, if the image switching button 202c is pressed while the 3D image of the work guidelines before the packaging work, as illustrated in Figure 3(a), is displayed, the image of the work guidelines before the packaging work shown in Figure 4(a) will be displayed in the work guidelines image display area 202.

[0056] The material information display area 203 displays information corresponding to the packaging specifications identified by the packaging specification code displayed in the product information display area 201, as information about the materials used in the work (packaging materials in this embodiment). Figure 2A illustrates a case where the type and number of packaging materials are displayed in the material information display area 203. For example, a scroll bar (not shown) may be displayed in the material information display area 203. The information displayed in the material information display area 203 may be scrolled by operating the scroll bar.

[0057] The cautionary information display area 204 displays information corresponding to the packaging specification identified by the packaging specification code displayed in the product information display area 201, as information indicating cautionary notes. Figure 2A illustrates an example where the aforementioned cautionary information is displayed as text in the cautionary information display area 204 ("***" represents text). As mentioned above, the cautionary notes are matters that field workers W1~W2 should pay attention to during on-site work. For example, a scroll bar (not shown) may be displayed in the cautionary information display area 204. The information displayed in the cautionary information display area 204 may be scrolled by operating the scroll bar.

[0058] The work confirmation input information display field 205 displays information corresponding to the packaging specification identified by the packaging specification code displayed in the product information display field 201, as work confirmation input information. Figure 2A illustrates a case where the work confirmation input information is information that allows field workers W1 to W2 to input that they have performed confirmation after on-site work for each of the multiple confirmation items. Figure 2A illustrates a case where field workers W1 to W2 check the checkboxes corresponding to the confirmation items through input operations on the on-site work terminal devices 124a to 124b. For example, a scroll bar (not shown) may be displayed in the work confirmation input information display field 205. The information displayed in the work confirmation input information display field 205 may be scrolled by operating the scroll bar.

[0059] The terminal image display area 206 displays the terminal image captured. As mentioned above, the terminal image captured is an image taken using the field work terminal devices 124a to 124b. The terminal image captured is an image of an area that includes a part where it is necessary to request the work supervisor to check the quality of coil C, for example. In other words, by taking a picture of coil C after a certain work using the field work terminal devices 124a to 124b, it is possible to visualize the content of the request to the work supervisor and prove the quality of coil C. Specifically, for example, if there is a defect at the tip of coil C, the work supervisor may not be able to make an accurate judgment based on text information alone, but by using the terminal image captured, the quality of coil C can be judged accurately and easily even remotely. Also, for example, if the condition of coil C is not easy for field workers W1 to W2 to express in text information, using the terminal image captured can prevent important information regarding the quality of coil C from being conveyed to the work supervisor. Furthermore, by recording the results of the quality assessment of coil C using terminal images, it is possible to review the results (confirm any problems found in the quality assessment) even after coil C has been transported to the customer. For example, a scroll bar (not shown) may be displayed in the terminal image display area 206. The information (terminal images) displayed in the terminal image display area 206 may be scrolled by operating the scroll bar.

[0060] The memo input field 207 displays comments about the work entered by the field worker through input operations on the field work terminal devices 124a to 124b. For example, the memo input field 207 displays information entered by hand using a stylus pen. For example, if it is necessary to request the work supervisor to check the quality of coil C, the confirmation request is entered into the memo input field 207. Note that, for example, a scroll bar (not shown) may be displayed in the memo input field 207. The information displayed in the memo input field 207 may be scrolled by operating the scroll bar.

[0061] The field work comment input field 208 displays pre-set confirmation requests for the work supervisor. For example, the field work comment input field 208 displays multiple comments categorized according to the type of work object's condition as candidates for confirmation requests, describing the condition and location of coil C that needs confirmation from the work supervisor. Figure 2A illustrates the case where the type of work object's condition and the candidates for confirmation requests are displayed in pull-down menus (see pull-down menus 208a to 208d). The field worker selects the appropriate confirmation request from the multiple candidates by operating the field work terminal devices 124a to 124b. Note that the pull-down menus 208a to 208d may contain blanks. Furthermore, Figure 2A illustrates a case where the name input field 208e of the field worker who made the input in the field work comment input field 208 is displayed in the field work comment input field 208.

[0062] Furthermore, the aforementioned memo input field 207 may be used, for example, to input confirmation requests that are not represented in the list of confirmation request items displayed in the field work comment input field 208 (pull-down menu 208c~208d).

[0063] The work instruction comment input field 209 displays the content of the work that the field worker needs to perform as a response when a field worker requests confirmation of the quality of coil C, etc. Figure 2A illustrates a case where a pull-down menu 209a is displayed in the work instruction comment input field 209, showing candidate response items in a pull-down format. Note that the pull-down menu 209a may contain blanks. The work instructor selects the appropriate response item from the multiple candidate response items by operating the work instruction terminal device 125.

[0064] Furthermore, Figure 2A illustrates a case where the free-form input field 209b is displayed in the work instruction comment input field 209. The free-form input field 209b displays comments related to the work instruction entered by the work instruction operator through input operations on the work instruction terminal device 125. The work instruction comment input field 209 may also be used to enter answers that are not represented in the answer options displayed in the pull-down menu 209a. Furthermore, Figure 2A illustrates a case where the name input field 209c of the work instruction supervisor who made the input in the work instruction comment input field 209 is displayed in the work instruction comment input field 209.

[0065] The alarm display area 210 displays alarm information to prompt the field worker to confirm that they have performed the work corresponding to an item if, for example, coil C, identified by the product ID displayed in the product information display area 201, reaches the work confirmation position, but there are unchecked items in the work confirmation input information display area 205. The work confirmation position may be, for example, position 12. In this embodiment, the case in which coil C reaching the work confirmation position is the work confirmation condition is illustrated. In this embodiment, the case in which the information displayed in the work confirmation input information display area 205 is the work confirmation input information is illustrated. In this embodiment, the case in which checking the checkbox in the work confirmation input information display area 205 is the confirmation input is illustrated. In this embodiment, the case in which the alarm information displayed in the alarm display area 210 is work prompting information is illustrated.

[0066] The email notification button 211 is a button that is pressed by field workers W1 to W2 when the aforementioned confirmation request items are entered. In this embodiment, when the email notification button 211 is pressed, a confirmation request is sent via email to the work instruction terminal device 125. Note that the email notification button 211 may be disabled on the work instruction terminal device 125.

[0067] The action input notification button 212 is a button that is pressed by the work supervisor when the aforementioned response information is entered. In this embodiment, when the action input notification button 212 is pressed, information indicating that the response information has been entered is displayed on the work management screen 200 as an example. For example, the information indicating that the response information has been entered may be displayed by changing the color of the action input notification button 212. Alternatively, for example, the fact that the response information has been entered may be displayed as text in the alarm display field 210. Note that the action input notification button 212 may be disabled on the field work terminal devices 124a to 124b.

[0068] The work performance image display instruction button 213 is pressed to display the work performance image (in this embodiment, an image taken by the camera 121a to 121d) of coil C, which is identified by the product ID displayed in the product information display field 201. The work performance image display instruction button 213 may be a button that can be operated from both the field work terminal devices 124a to 124b and the work instruction work terminal device 125.

[0069] Figure 2B shows an example of the work performance display screen 220. Figure 2B illustrates the case where the work performance display screen 220 is a GUI. Figure 2B illustrates the case where the work performance display screen 220 displays work performance image display areas 221a to 221d and a back button 222. Specifically, Figure 2B illustrates the case where work performance images taken by the shooting devices 121a, 121b, 121c, and 121d are displayed in the work performance image display areas 221a, 221b, 221c, and 221d, respectively. Also, Figure 2B illustrates the case where, when the back button 225 is pressed, the display of the work performance display screen 220 ends and the work management screen 200 shown in Figure 2A is displayed. Thus, in this embodiment, an example is illustrated in which the work guideline image displayed in the work guideline image display field 202 and the work performance images displayed in the work performance image display areas 221a to 221d are switched between.

[0070] <<Work management device 123, on-site work terminal devices 124a-124b, work instruction work terminal device 125>> Figure 5 shows an example of the functional configuration of the work management device 123, the field work terminal devices 124a to 124b, and the work instruction work terminal device 125. An example of the functions of the work management device 123, the field work terminal devices 124a to 124b, and the work instruction work terminal device 125 will be explained with reference to Figure 5 and other figures. Note that at least some of the functions of the work management device 123, the field work terminal devices 124a to 124b, and the work instruction work terminal device 125 that are possessed by multiple different devices may be realized by a single device. Also, the functions of the work management device 123 may be realized by multiple devices. Similarly, the functions of the field work terminal devices 124a to 124b and the work instruction work terminal device 125 may each be realized by multiple devices.

[0071] The work management device 123, the field work terminal devices 124a to 124b, and the work instruction work terminal device 125 each have, for example, one or more hardware processors such as a CPU (Central Processing Unit) and one or more memory such as RAM (Random Access Memory) and ROM (Read Only Memory) as hardware, and perform various calculations by executing one or more programs stored in memory using one or more hardware processors. Furthermore, the field work terminal devices 124a to 124b and the work instruction work terminal device 125 may each have input devices and output devices as hardware. The input devices and output devices may be located outside the field work terminal devices 124a to 124b and the work instruction work terminal device 125. Furthermore, the work management device 123, the field work terminal devices 124a to 124b, and the work instruction work terminal device 125 may be implemented by a PLC (Programmable Logic Controller) or by dedicated hardware such as an ASIC (Application Specific Integrated Circuit).

[0072] As mentioned above, in this embodiment, the example given is that the field work terminal devices 124a to 124b are portable terminal devices that also function as imaging devices. Furthermore, the field work terminal devices 124a to 124b can be implemented using devices with the same hardware configuration and devices with the same functional configuration. Therefore, in the following, a detailed explanation of the field work terminal device 124a will be given, and a detailed explanation of the field work terminal device 124b will be omitted. Note that the number of field work terminal devices provided by the work management system is not limited to two; it may be one, three or more, or any number of devices.

[0073] <<<Work management device 123>>> First, let me explain an example of the functions of the work management device 123. Figure 5 illustrates a case where the work management device 123 includes a work information acquisition unit 123a, a work guideline image acquisition unit 123b, a work performance image acquisition unit 123c, a control unit 123d, a storage unit 123e, a receiving unit 123f, and a transmitting unit 123g.

[0074] The control unit 123d performs processing that is not performed by other functional units of the work management device 123. The receiving unit 123f receives various types of information transmitted from external devices. The storage unit 123e stores various types of information.

[0075] In this embodiment, an example is given of the case in which the receiving unit 123f receives product location information. The product location information includes, for example, a product ID (identification information of coil C), a product location (the position where coil C is located), and a date and time. The date and time includes, for example, at least one of the date and time when coil C identified by the product ID reached the product location (position) and the date and time when coil C identified by the product ID passed through the product location (position) (the date and time when it moved to the next product location).

[0076] For example, the date and time when each coil C reaches position 1 may be determined by on-site workers W1 to W2 when performing on-site work at position 1, or it may be determined based on the work schedule. Alternatively, the date and time when each coil C reaches each position 2 to 12 may be determined based on, for example, the conveying speed and direction of the coil C by the belt conveyor 111, the elapsed time since the date and time when each coil C reached position 1, and the length of each position 2 to 12 in the conveying direction of the belt conveyor 111. The date and time when each coil C passes through position 12 may also be determined. The date and time information determined in this manner may be included in the product position information. For example, the work management device 123 may create the product position information.

[0077] The control unit 123d stores the product location information received by the receiving unit 123f in the storage unit 123e. Figure 6A shows an example of product location information 601. If new product location information with the same product ID as the product location information stored in the storage unit 123e is received by the receiving unit 123f, the control unit 123d may update the product location information stored in the storage unit 123e. In this embodiment, an example is given in which the product location information 601 identifies which coil C is located at which position.

[0078] Furthermore, this embodiment illustrates a case where the receiving unit 123f receives a work performance image. In this embodiment, it is illustrated that the work performance image is accompanied by the ID of the shooting device 121a to 121d that took the image, and the date and time of shooting. As mentioned above, in this embodiment, it is illustrated that shooting devices 121a and 121b each take work performance images of coil C at position 1 from the front and rear sides, respectively, and shooting devices 121c and 121d each take work performance images of coil C at position 11 from the front and rear sides.

[0079] The work performance image acquisition unit 123c acquires work performance images. In this embodiment, an example is given of the case in which the work performance image acquisition unit 123c acquires work performance images received by the receiving unit 123f. For example, the work performance image acquisition unit 123c determines whether or not a product (coil C) is present at the shooting position based on the product location information 601 stored in the storage unit 123e. In this embodiment, an example is given of the case in which the shooting positions are positions 1 and 11. If, as a result of this determination, it is determined that a product (coil C) is present at the shooting position, the work performance image acquisition unit 123c acquires the latest work performance image at that shooting position. The work performance image acquisition unit 123c may also acquire the latest work performance image at the shooting position from among the work performance images received by the receiving unit 123f. Alternatively, the work performance image acquisition unit 123c may request the acquisition of a work performance image at the shooting position via the transmitting unit 123g, and in response to this request, acquire the work performance image at that shooting position received by the receiving unit 123f. The work performance image acquisition unit 123c then stores the work performance image information in the storage unit 123e. The work performance image information includes, for example, the work performance image, the date and time the work performance image was taken, and the location (shooting position) where the work performance image was taken. Figure 6B shows an example of work performance image information 602.

[0080] Furthermore, this embodiment illustrates a case where the receiving unit 123f receives work information from an external device (not shown). The work information includes, for example, a product ID, a packaging specification code, and product attribute information. The packaging specification code is identification information for the packaging specification. The product attribute information may include, for example, product attribute information necessary when creating a 3D image based on a 3D model. The product attribute information may also include, for example, information indicating the size of the product.

[0081] The work information acquisition unit 123a acquires work information. In this embodiment, an example is given in which the work information acquisition unit 123a acquires work information received by the receiving unit 123f. Note that the work information may be input to the work management device 123 based on an input operation of information indicating work information to the work management device 123.

[0082] Furthermore, this embodiment illustrates a case where packaging specification information is pre-stored in the storage unit 123e. Packaging specification information includes, for example, a packaging specification code and packaging specifications. As mentioned above, this embodiment illustrates a case where packaging material information, work confirmation input information, and information indicating precautions are included in the packaging specifications. Figure 6C is a diagram showing an example of packaging specification information 603. Packaging material information is information indicating the packaging materials to be used. Work confirmation input information is information displayed in the work confirmation input information display field 205 shown in Figure 2A. Information indicating precautions is information displayed in the precautions display field 204 shown in Figure 2A.

[0083] Furthermore, this embodiment illustrates a case where standardized information is pre-stored in the storage unit 123e. Standardized information includes, for example, information displayed as standardized comments in the field work comment input field 208 and the work instruction comment input field 209, and a packaging specification code. Figure 6D shows an example of standardized information 604 displayed as a standardized comment in the field work comment input field 208. Figure 6E shows an example of standardized information 605 displayed as a standardized comment in the work instruction comment input field 209.

[0084] Furthermore, this embodiment illustrates a case where work guideline image information is pre-stored in the storage unit 123e. The work guideline image information includes, for example, work guideline images and packaging specification codes. In addition, this embodiment illustrates a case where the work guideline images include work guideline images taken before the packaging work and work guideline images taken after the packaging work. Figure 6F is a diagram showing an example of work guideline image information 606. Note that the work guideline image information 606 may also include information about the storage location of the work guideline image files.

[0085] In this embodiment, we illustrate a case where the work guideline image acquisition unit 123b acquires a work guideline image for each packaging specification. For example, the work guideline image acquisition unit 123b acquires a work guideline image corresponding to the packaging specification code included in the work information acquired by the work information acquisition unit 123a by reading it from the work guideline image information 606.

[0086] Furthermore, for example, the work guideline image acquisition unit 123b reads packaging material information corresponding to the packaging specification code included in the work information acquired by the work information acquisition unit 123a from the packaging specification information 603, and creates a 3D work guideline image corresponding to the packaging specification code based on the 3D model corresponding to the packaging material information and the product attribute information included in the work information acquired by the work information acquisition unit 123a. The 3D work guideline image is created, for example, by using known 3D computer graphics techniques, so a detailed explanation of the method for creating the 3D work guideline image is omitted here. The work guideline image acquisition unit 123b may also create the 3D work guideline image using the method described in Patent Document 1. The work guideline image acquisition unit 123b may also store the 3D work guideline image information in the storage unit 123e. The 3D work guideline image information includes, for example, the 3D work guideline image and the packaging specification code. Figure 6G shows an example of 3D work guideline image information 607. Furthermore, the 3D image information 607 of the work instructions may also include information about the storage location of the file containing the 3D image of the work instructions.

[0087] Furthermore, in this embodiment, an example is given in which the control unit 123d reads from the packaging specification information 603 work confirmation input information and information indicating precautions corresponding to the packaging specification code included in the work information acquired by the work information acquisition unit 123a.

[0088] In this embodiment, as described above, an example is given in which information corresponding to the packaging specification code included in the work information acquired by the work information acquisition unit 123a is obtained, including packaging material information, work guideline images (work guideline 3D image and work guideline photographic image), work confirmation input information, information indicating precautions, and standard information.

[0089] In this embodiment, we will illustrate a case in which the control unit 123d creates work management screen information as one of the screen information based on the product ID included in the work information acquired by the work information acquisition unit 123a and the various information mentioned above corresponding to the packaging specification code included in the work information. The work management screen information is the information necessary to display the work management screen 200. The work management screen information created based on the work information acquired by the work information acquisition unit 123a may include information indicating that the checkbox in the work confirmation input information display field 205, the terminal captured image display field 206, the memo input field 207, the name input fields 208e and 209c, and the alarm display field 210 should be left blank.

[0090] Furthermore, in this embodiment, an example is given in which the receiving unit 123f receives operation information from the field work terminal device 124a and the work instruction work terminal device 125, respectively. The operation information is information indicating the content of the input operation performed on the field work terminal device 124a and the work instruction work terminal device 125.

[0091] In this embodiment, an example is given where the operation information includes screen call information and screen operation content information. Screen call information is information indicating the content of the input operation performed on the field work terminal device 124a and the work instruction work terminal device 125 when a screen is called. In this embodiment, an example is given where the called screen includes the work management screen 200, the work performance display screen 220, and the work confirmation screen 230, which will be described later. Screen operation content information is information indicating the content of the input operation performed on the screen. In this embodiment, an example is given where the screen on which the input operation is performed includes the work management screen 200, the work performance display screen 220, and the work confirmation screen 230, which will be described later.

[0092] Furthermore, in this embodiment, we illustrate the case in which a product ID is added to the screen call information for the work management screen 200 transmitted from the work instruction terminal device 125. In this case, the receiving unit 123f receives information with a product ID added as screen call information for the work management screen 200. The control unit 123d creates work management screen information corresponding to the product (coil C) identified by the product ID added to the screen call information for the work management screen 200. The transmitting unit 123g transmits the work management screen information to the work instruction terminal device 125.

[0093] The work management screen information transmitted based on the screen call information for the work management screen 200 may include information indicating that the checkbox in the work confirmation input information display field 205, the terminal captured image display field 206, the memo input field 207, the name input fields 208e and 209c, and the alarm display field 210 should be left blank.

[0094] Furthermore, in this embodiment, when screen call information for a work management screen 200 corresponding to a product (coil C) identified by the same product ID as the work information acquired by the work information acquisition unit 123a is received by the receiving unit 123f, the control unit 123d creates the work management screen information and the transmission unit 123g transmits the work management screen information, as described above.

[0095] In this embodiment, we illustrate a case in which the work management screen 200 is displayed with the checkbox in the work confirmation input information display field 205, the terminal captured image display field 206, the memo input field 207, the name input fields 208e and 209c, and the alarm display field 210 all blank, as described above.

[0096] In this embodiment, when the receiving unit 123f receives screen operation information for the work management screen 200, the control unit 123d stores the screen operation information other than button operations in the storage unit 123e as an example. An example of an input operation performed on the work management screen 200 is as described above with reference to Figure 2A. Among the screen operation information, information other than button operations includes, for example, information indicating the content of input operations for the work confirmation input information display field 205, the terminal captured image display field 206, the memo input field 207, and the name input fields 208e and 209c. In addition, among the screen operation information, information indicating button operations includes, for example, information indicating the pressing of the email notification button 211, the action input notification button 212, and the work performance image display instruction button 213.

[0097] Furthermore, in this embodiment, when the receiving unit 123f receives screen operation information indicating that the email notification button 211 has been pressed, the control unit 123d creates an email to notify the work supervisor that a work confirmation request has been made and sends it to the work instruction terminal device 125. In this case, the contents of the email may be displayed on the work instruction terminal device 125. Then, based on the work supervisor's input operation to the work instruction terminal device 125 after viewing the email, screen call information for the work management screen 200 may be created on the work instruction terminal device 125 and sent to the work management device 123.

[0098] Furthermore, based on the work supervisor's input operation in the work instruction comment input field 209 after viewing the email, screen operation information indicating the content of the input operation may be created by the work instruction terminal device 125 and transmitted to the work management device 123. In addition, based on the work supervisor's press of the action input notification button 212 after the input operation in the work instruction comment input field 209, screen operation information indicating that the action input notification button 212 has been pressed may be created by the work instruction terminal device 125 and transmitted to the work management device 123. When the receiving unit 123f receives screen operation information indicating that the action input notification button 212 has been pressed, the control unit 123d may create work management screen information instructing the work management screen 200 displaying the pressed action input notification button 212 to display information indicating that a response has been entered. In this case, the transmitting unit 123g may transmit the work management screen information to the field work terminal device 124a displaying the work management screen 200. Furthermore, the field work terminal device 124a may display information on the work management screen 200 indicating that a response has been entered. This allows field workers to be notified that a response has been entered. The display of information indicating that a response has been entered can be done, for example, by changing the color of the action input notification button 212 or by displaying text in the alarm display field 210 indicating that a response has been entered.

[0099] Furthermore, in this embodiment, we illustrate a case where the receiving unit 123f receives screen call information for the work performance display screen 220 from the field work terminal device 124a and the work instruction work terminal device 125. The screen call information for the work performance display screen 220 is created, for example, based on the pressing of the work performance image display instruction button 213. In this embodiment, we illustrate a case where the control unit 123d reads the work performance image of the product ID corresponding to the work management screen 200 displaying the pressed work performance image display instruction button 213 from the storage unit 123e, and creates work performance display screen information as one of the screen information based on the read work performance image. In this case, the transmitting unit 123g may transmit the work performance display screen information to the field work terminal device 124a or the work instruction work terminal device 125 that is displaying the work management screen 200.

[0100] Furthermore, in this embodiment, an example is given in which the control unit 123d determines whether there are any unchecked items in the work confirmation input information display field 205 for a product (coil C) in a work confirmation position (for example, position 12) based on the product location information 601 and operation information (content of input operation for the work confirmation input information display field 205) stored in the storage unit 123e. If there are any unchecked items in the work confirmation input information display field 205 for a product (coil C) in a work confirmation position, the control unit 123d may create work management screen information that instructs the work management screen 200 corresponding to the product ID of the product to display alarm information. In this case, the transmission unit 123g may transmit the work management screen information to the field work terminal device 124a that is displaying the work management screen 200. As a result, alarm information prompting the field worker W1 to confirm that the work corresponding to the item has been performed is displayed in the alarm display field 210 of the work management screen 200.

[0101] Furthermore, this embodiment illustrates a case where the receiving unit 123f receives a terminal image. In this embodiment, it is illustrated that the terminal image is accompanied by the ID of the field work terminal device 124a that took the image and the date and time of capture. In this case, the control unit 123d may create terminal image information and store it in the storage unit 123e. The terminal image information includes, for example, the terminal image, product ID, product location, and date and time of capture. The control unit 123d may, for example, identify the product (coil C) located at the position where the field work terminal device 124a identified by the ID exists, based on the ID and date and time of capture of the field work terminal device 124a accompanied by the terminal image and the product location information 601 (see Figure 6A) stored in the storage unit 123e. Figure 6H shows an example of terminal image information 608.

[0102] Furthermore, in this embodiment, an example is given in which the control unit 123d creates work performance information and stores it in the storage unit 123e. The work performance information is, for example, information indicating the work performed in the packaging equipment for each product (coil C). The work performance information includes, for example, the product ID, the packaging specification code, and the work date and time. The work date and time may be, for example, the date and time when the work in the packaging equipment was completed. The work date and time may also be, for example, the date and time when the product reached position 12, or the date and time when the product passed through position 12. The work performance information may be created for each work group consisting of all the work performed on the packaging equipment. Figure 6I shows an example of work performance information 609.

[0103] Furthermore, in this embodiment, we illustrate a case where the control unit 123d creates work confirmation screen information as one of the screen information items. Work confirmation screen information is information necessary to display the work confirmation screen. The work confirmation screen is displayed on the field work terminal device 124a and the work instruction work terminal device 125 in order to search for and display work performance information.

[0104] Figure 2C shows an example of the work confirmation screen 230. Figure 2C illustrates a case where the work confirmation screen 230 displays the work performance search condition input field 231, the search execution button 232, the work performance history display field 233, and the details display button 234. Figure 2C also illustrates a case where the work confirmation screen 230 is a GUI.

[0105] In Figure 2C, the search criteria for work performance information in the packaging equipment are entered in the work performance search criteria input field 231. Figure 2C illustrates a case where candidates for product ID, work date and time, and packaging specification code are displayed in pull-down menus (see pull-down menus 231a to 231c). Field workers select the product ID, work date and time, and packaging specification code corresponding to the work performance they want to search for from the candidates for product ID, work date and time, and packaging specification code by operating the field work terminal device 124a. Similarly, work supervisors select the product ID, work date and time, and packaging specification code corresponding to the work performance they want to search for from the candidates for product ID, work date and time, and packaging specification code. In this case, the search criteria are to search for work performance information for the work for which the selected product ID, work date and time, and packaging specification code are found. Note that one or two of the product ID, work date and time, and packaging specification code may be left unselected. In this case, the unselected items may not be included in the search criteria. Additionally, the pull-down menus 231a to 231c may contain spaces.

[0106] The search execution button 232 is a button pressed by field workers and work supervisors when searching for work performance information using the search criteria entered in the work performance search criteria input field 231. The work performance history display field 233 displays an overview of the work performance information 609 that matches the search criteria entered in the work performance search criteria input field 231. Figure 2C illustrates a case where work performance information is displayed for each work group consisting of all operations related to the packaging equipment. Figure 2C also illustrates a case where the work confirmation screen 230 is configured to allow the user to select one of the work performance information displayed in the work performance history display field 233.

[0107] On-site workers can select work performance information for which they want more detailed information from the work performance information whose summary is displayed in the work performance history display field 233 by operating the on-site work terminal device 124a. Similarly, work supervisors can select work performance information for which they want more detailed information from the work performance information whose summary is displayed in the work performance history display field 233 by operating the work instruction terminal device 125.

[0108] The details display button 234 is pressed by field workers and work supervisors to display detailed information about selected work performance information from the work performance information displayed in the work performance history display field 233. When the details display button 234 is pressed, the work management screen 200 corresponding to the selected work performance information from the work performance information displayed in the work performance history display field 233 is displayed on the field work terminal device 124a and the work instruction work terminal device 125.

[0109] In this embodiment, when the receiving unit 123f receives screen call information for the work confirmation screen 230 from the field work terminal device 124a and the work instruction work terminal device 125, the control unit 123d reads the work performance information 609 from the storage unit 123e and creates the work confirmation screen information as one of the screen information based on the read work performance information 609. Then, in this embodiment, the transmitting unit 123g transmits the work confirmation screen information to the requester of the screen call information. In the example shown in Figure 5, the requester of the screen call information is either the field work terminal device 124a or the work instruction work terminal device 125.

[0110] In this embodiment, we illustrate a case where the receiving unit 123f receives screen operation information, including the search conditions entered in the work performance search condition input field 231, as operation information when the search execution button 232 is pressed on the work confirmation screen 230. In this embodiment, the control unit 123d may create work confirmation screen information that instructs the storage unit 123e to read work performance information that matches the search conditions included in the operation information and to display an overview of the read work performance information on the work confirmation screen 230. In this case, the transmitting unit 123g may transmit the work confirmation screen information to the field work terminal device 124a or work instruction work terminal device 125 that is displaying the work confirmation screen 230. As a result, an overview of the work performance information that matches the search conditions entered in the work performance search condition input field 231 is displayed in the work performance history display field 233.

[0111] In this embodiment, when the detail display button 234 is pressed on the work confirmation screen 230, the receiving unit 123f receives screen call information, which includes work performance information selected from the summary of work performance information displayed in the work performance history display field 233, as operation information. In this embodiment, the control unit 123d extracts the product ID and packaging specification code from the work performance information included in the operation information to create work information, and outputs the work information to the work information acquisition unit 123a. Thus, in this embodiment, the work information acquisition unit 123a acquires work information based on the operation information for the work confirmation screen 230. In this embodiment, the creation and transmission of the work management screen 200 and the work performance display screen 220 are performed based on this work information as described above.

[0112] <<<Field work terminal device 124a>>> Next, an example of the functions of the field work terminal device 124a will be described. Figure 5 illustrates a case where the field work terminal device 124a comprises an imaging unit 124a1, a display processing unit 124a2, an operation input unit 124a3, a receiving unit 124a4, and a transmitting unit 124a5.

[0113] The imaging unit 124a1 captures a terminal image. The imaging unit 124a1 is realized, for example, by using an imaging optical system including an imaging lens, an image sensor, and an image processing circuit. As described above, in this embodiment, an example is given in which the ID of the field work terminal device 124a that captured the terminal image and the date and time of capture are added to the terminal image. The imaging unit 124a1 may also add the ID of the field work terminal device 124a that captured the terminal image and the date and time of capture to the terminal image.

[0114] The display processing unit 124a2 performs display processing on the display device provided by the field work terminal device 124a or on the display device connected to the field work terminal device 124a. The display device is a computer display. In this embodiment, an example is given in which the display processing unit 124a2 performs display processing on the work management screen 200, the work performance display screen 220, and the work confirmation screen 230 described above.

[0115] The operation input unit 124a3 receives the content of the input operation to the field work terminal device 124a and creates operation information indicating that content. As described above, this embodiment exemplifies a case where screen call information and screen operation content information are included in the operation information. Specific examples of operation information are as described above.

[0116] The transmitting unit 124a5 transmits the terminal captured image and operation information to the work management device 123. The receiving unit 124a4 receives screen information. In this embodiment, an example is shown where the screen information includes work management screen information, work performance display screen information, and work confirmation screen information.

[0117] <<<Work instruction terminal device 125>>> Next, an example of the functions of the work instruction terminal device 125 will be described. Figure 5 illustrates a case where the work instruction terminal device 125 comprises a display processing unit 125a, an operation input unit 125b, a receiving unit 125c, and a transmitting unit 125d.

[0118] The display processing unit 125a performs display processing on the display device provided by the work instruction terminal device 125 or on a display device connected to the work instruction terminal device 125. The display device is a computer display. In this embodiment, an example is given of the display processing unit 125a performing display processing on the work management screen 200, the work performance display screen 220, and the work confirmation screen 230 described above. In this embodiment, an example is given of the display processing unit 125a performing processing to display on the display device the contents of an email notifying the work instructioner that a work confirmation request has been received.

[0119] The operation input unit 125b receives the content of the input operation to the work instruction terminal device 125 and creates operation information indicating that content. As described above, this embodiment exemplifies a case where screen call information and screen operation content information are included in the operation information. Specific examples of operation information are as described above.

[0120] The transmitting unit 125d transmits operation information to the work management device 123. The receiving unit 125c receives screen information. In this embodiment, an example is shown where the screen information includes work management screen information, work performance display screen information, and work confirmation screen information.

[0121] <Work management method> Next, an example of a work management method performed using the work management system of this embodiment will be described with reference to the flowcharts in Figures 7A to 7I. For the sake of simplicity, this example assumes that the information necessary for the execution of the flowcharts in Figures 7A to 7I is stored in the work management device 123, the field work terminal device 124a, and the work instruction work terminal device 125 before the flowcharts begin.

[0122] Figure 7A is a flowchart illustrating an example of the process for determining the position of the product (the position of coil C). The flowchart in Figure 7A is performed, for example, each time product position information 601 is received by the receiving unit 123f. First, in step S701, the receiving unit 123f receives product location information. Finally, in step S702, the control unit 123d stores the product location information received in step S701 in the storage unit 123e (see Figure 6A). As mentioned above, if new product location information with the same product ID is received in step S701, the control unit 123d may update the product location information.

[0123] Figure 7B is a flowchart illustrating an example of the process for acquiring work performance images. The flowchart in Figure 7B is performed, for example, each time the product location information 601 stored in the memory unit 123e is updated.

[0124] First, in step S711, the work performance image acquisition unit 123c determines whether or not a product (coil C) is present at the shooting position based on the product position information 601 stored in the storage unit 123e. If the result of this determination is that no product is present at the shooting position (NO in step S711), the process according to the flowchart in Figure 7B is terminated.

[0125] On the other hand, if a product is present at the shooting position (if the answer is YES in step S711), the process in step S712 is performed. In step S712, the work performance image acquisition unit 123c acquires the latest work performance image at the shooting position.

[0126] Finally, in step S713, the work performance image acquisition unit 123c stores the work performance image information, which includes the work performance image acquired in step S712, the date and time the work performance image was taken, and the location (shooting position) where the work performance image was taken, into a storage medium (see Figure 6B).

[0127] Figure 7C is a flowchart illustrating an example of the process for displaying the work management screen 200. The flowchart in Figure 7C is performed, for example, each time work information is received by the receiving unit 123f.

[0128] First, in step S731, the work information acquisition unit 123a acquires work information. The work information includes, for example, a product ID, a packaging specification code, and product attribute information. The work information acquisition unit 123a may acquire work information received by the receiving unit 123f, or it may acquire work information entered into the work management device 123 based on an input operation of information indicating work information to the work management device 123.

[0129] Next, in step S732, the control unit 123d acquires the operation information (screen call information) received by the receiving unit 123f. If the source of the operation information (screen call information) is the field work terminal device 124a, work management screen information to be displayed on the field work terminal device 124a is created. On the other hand, if the source of the operation information (screen call information) is the work instruction work terminal device 125, work management screen information to be displayed on the work instruction work terminal device 125 is created.

[0130] Next, in step S733, the work guideline image acquisition unit 123b acquires (creates) a three-dimensional work guideline image based on the work information. Next, in step S734, the work guideline image acquisition unit 123b acquires (reads out) the work guideline image corresponding to the work information from the storage unit 123e.

[0131] Next, in step S735, the control unit 123d retrieves (reads) information corresponding to the packaging specification code included in the work information from the storage unit 123e, including packaging material information, work confirmation input information, information indicating precautions, and standard information (see Figures 6C to 6E). Then, the control unit 123 creates work management screen information based on this information retrieved from the storage unit 123e and the work guideline images (work guideline 3D image and work guideline captured image) acquired in steps S733 to S734.

[0132] Next, in step S736, the transmitting unit 123g transmits the work management screen information to the requesting device. The requesting device is the field work terminal device 124a or the work instruction work terminal device 125 that transmits the operation information (screen call information). The receiving unit 124a1 or 125c of the requesting device then receives the work management screen information.

[0133] Finally, in step S737, the display processing unit 124a2 or 125a of the requesting device causes the work management screen 200 to be displayed on the display device of the device or on a display device connected to the device.

[0134] Figure 7D is a flowchart illustrating an example of the process for displaying terminal images on the work management screen 200. The flowchart in Figure 7D is performed, for example, each time a field worker W1 performs an operation to capture a terminal image after the work management screen 200 is displayed on the field work terminal device 124a.

[0135] First, in step S741, the imaging unit 124a1 captures a terminal image. As mentioned above, in this embodiment, an example is given in which the ID of the field work terminal device 124a that captured the terminal image and the date and time of capture are added to the terminal image. The imaging unit 124a1 may also add the ID of the field work terminal device 124a that captured the terminal image and the date and time of capture to the terminal image.

[0136] Next, in step S742, the transmitting unit 124a5 transmits the terminal image captured in step S741 to the work management device 123. The receiving unit 123f of the work management device 123 receives the terminal image.

[0137] Finally, in step S743, the control unit 123d creates terminal image information based on the terminal image received in step S742 and the product location information 601 stored in the storage unit 123e (see Figure 6A), displays it on the work management screen 200, and stores it in the storage unit 123e (see Figure 6H).

[0138] Figure 7E is a flowchart illustrating an example of the process when a field worker requests confirmation of their work from a work supervisor. The flowchart in Figure 7E is performed, for example, each time the email notification button 211 is pressed.

[0139] In the first step S751, the operation input unit 124a3 of the field work terminal device 124a, which is displaying the pressed email notification button 211 (work management screen 200), creates screen operation content information indicating that the email notification button 211 has been pressed as operation information. The transmission unit 124a5 of the field work terminal device 124a transmits this operation information to the work management device 123. The receiving unit 123f of the work management device 123 receives this operation information.

[0140] Next, in step S752, the control unit 123d creates an email to notify the work supervisor that a request for work confirmation has been received. Next, in step S753, the transmission unit 123g of the work management device 123 sends the email created in step S752 to the work instruction terminal device 125. The receiving unit 125c of the work instruction terminal device 125 receives the email.

[0141] Finally, in step S754, the display processing unit 125a of the work instruction terminal device 125 displays the contents of the email received in step S753 on the display device of the work instruction terminal device 125 or on the display device connected to the work instruction terminal device 125.

[0142] Figure 7F is a flowchart illustrating an example of the process when a work manager enters responses to work confirmation requests from field workers. The flowchart in Figure 7F is executed, for example, each time the action input notification button 212 is pressed after the input operation in the work instruction comment input field 209 on the work management screen 200 has been completed.

[0143] In the first step S761, the operation input unit 125b of the work instruction terminal device 125 creates screen operation content information as operation information, indicating that the action input notification button 212 has been pressed. The transmission unit 125 of the work instruction terminal device 125 transmits this operation information to the work management device 123. The receiving unit 123f of the work management device 123 receives this operation information.

[0144] Next, in step S762, the control unit 123d creates work management screen information that instructs the system to display information indicating that the answer items have been entered. Next, in step S763, the transmission unit 123g of the work management device 123 transmits the work management screen information created in step S762 to the field work terminal device 124a that requested work confirmation according to the flowchart in Figure 7E. The receiving unit 124a4 of the field work terminal device 124a receives the work management screen information.

[0145] Finally, in step S764, the display processing unit 124a2 of the field work terminal device 124a that requested confirmation of the work displays information indicating that the response items have been entered on the display device of the field work terminal device 124a or on the display device connected to the field work terminal device 124a, based on the work management screen information received in step S763. For example, the display processing unit 124a2 may change the color of the action input notification button 212. Alternatively, the display processing unit 124a2 may display text in the alarm display field 210 indicating that the response items have been entered.

[0146] Figure 7G is a flowchart illustrating an example of the process for displaying the work performance display screen 220. The flowchart in Figure 7G is performed, for example, each time the work performance image display instruction button 213 on the work management screen 200 is pressed. Here, we will illustrate the case where the work performance image display instruction button 213 on the work management screen 200 displayed on the work instruction terminal device 125 is pressed. If the work performance image display instruction button 213 on the work management screen 200 displayed on the field work terminal device 124a is pressed, then, for example, in the following explanation, the display processing unit 125a, operation input unit 125b, receiving unit 125c, and transmitting unit 125d should be replaced with the display processing unit 124a2, operation input unit 124a3, receiving unit 124a4, and transmitting unit 124a5, respectively.

[0147] In the first step S771, the operation input unit 125b of the work instruction terminal device 125 creates screen call information for the work performance display screen 220 as operation information. The transmission unit 125 of the work instruction terminal device 125 transmits the operation information to the work management device 123. The receiving unit 123f of the work management device 123 receives the operation information.

[0148] Next, in step S772, the control unit 123d reads the work performance image of the product ID corresponding to the work management screen 200 displayed on the work instruction terminal device 125 from the storage unit 123e, and creates work performance display screen information as screen information based on the read work performance image.

[0149] Next, in step S773, the transmission unit 123g of the work management device 123 transmits the work performance display screen information created in step S772 to the work instruction terminal device 125. The receiving unit 125c of the work instruction terminal device 125 receives the work performance display screen information.

[0150] Next, in step S774, the display processing unit 125a of the work instruction terminal device 125 displays the work performance display screen 220 on the display device of the work instruction terminal device 125 or on the display device connected to the work instruction terminal device 125, based on the work performance display screen information received in step S773.

[0151] Next, in step S775, the operation input unit 125b of the work instruction terminal device 125 waits until the back button 225 displayed on the work performance display screen 220 is pressed. When the back button 225 is pressed (if the answer in step S775 is YES), the process in step S776 is performed.

[0152] In step S776, the display processing unit 125a stops the display of the work performance display screen 220 and resumes the display of the work management screen 200. The operation input unit 125b may also create operation information indicating that the back button 225 has been pressed. In this case, the transmission unit 125d transmits this operation information to the work management device 123. Once the processing in step S776 is completed, the processing according to the flowchart in Figure 7G is completed.

[0153] Figure 7H is a flowchart illustrating an example of the process for prompting field workers to confirm that they have completed a task. The flowchart in Figure 7H is performed, for example, each time the product location information 601 is updated.

[0154] In the first step S781, the control unit 123d determines whether the work confirmation condition has been met. As mentioned above, in this embodiment, the work confirmation condition is exemplified as the coil C reaching the work confirmation position. Whether the product (coil C) has arrived at the work confirmation position is determined, for example, based on the product position information 601.

[0155] If the result of this determination is that the work confirmation condition is not met (the result is NO in step S781), the process according to the flowchart in Figure 7H is terminated. On the other hand, if the work confirmation condition is met (the result is YES in step S781), the process in step S782 is performed.

[0156] In step S782, the control unit 123d determines whether or not confirmation input of work being performed has been made to the work management screen 200 for the product (coil C) in the work confirmation position. In this embodiment, it is exemplified that confirmation input of work being performed is indicated when all checkboxes displayed in the work confirmation input information display field 205 are checked. Based on this determination, it is determined whether or not there are any unchecked items.

[0157] If, as a result of this determination, confirmation input that the work has been performed has been made (YES in step S782), the process according to the flowchart in Figure 7H is terminated. On the other hand, if confirmation input that the work has been performed has not been made (NO in step S782), the process in step S783 is performed.

[0158] In step S783, the control unit 123d creates work prompt information, which is information to prompt the field worker to confirm that work has been performed on the product in the work confirmation position. In this embodiment, the case in which the work prompt information is the aforementioned alarm information is illustrated. In this case, the control unit 123d creates work management screen information that instructs the work management screen 200 to display the alarm information on the product ID of the product in the work confirmation position.

[0159] Next, in step S784, the transmitting unit 123g of the work management device 123 transmits the work prompting information (work management screen information) created in step S783 to the field work terminal device 124a which is displaying the work management screen 200. The receiving unit 124a4 of the field work terminal device 124a receives the work prompting information (work management screen information).

[0160] Finally, in step S785, the display processing unit 124a2 of the field work terminal device 124a displays the work prompting information (work management screen information) received in step S784 on the display device of the field work terminal device 124a or on a display device connected to the field work terminal device 124a. For example, alarm information to prompt the field worker to confirm that they have performed the work corresponding to the unchecked items in the work confirmation input information display field 205 is displayed in the alarm display field 210 of the work management screen 200 as an example of work prompting information. Thus, in this embodiment, the display processing unit 124a2 has the function of an output unit. As mentioned above, the work prompting information may also be sound information, for example. In this case, the work prompting information may be output by a device other than the display device (for example, a sound-producing device such as a buzzer).

[0161] Figure 7I is a flowchart illustrating an example of the process when work confirmation is performed retrospectively. The flowchart in Figure 7I is performed, for example, when an input operation is made to display the work confirmation screen 230. Here, we illustrate the case where the work confirmation screen 230 is displayed on the work instruction terminal device 125. If the work confirmation screen 230 is displayed on the field work terminal device 124a, then, for example, in the following explanation, the display processing unit 125a, operation input unit 125b, receiving unit 125c, and transmitting unit 125d can be replaced with the display processing unit 124a2, operation input unit 124a3, receiving unit 124a4, and transmitting unit 124a5, respectively.

[0162] In the first step S791, the display processing unit 125a of the work instruction terminal device 125 causes the work confirmation screen 230 to be displayed on the display device of the work instruction terminal device 125 or on a display device connected to the work instruction terminal device 125.

[0163] Next, in step S792, the operation input unit 125b of the work instruction terminal device 125 waits until the search execution button 232 is pressed. When the search execution button 232 is pressed (if the answer in step S792 is YES), the process in step S793 is performed.

[0164] In step S793, the operation input unit 125b of the work instruction terminal device 125 creates screen operation information including the search conditions entered in the work performance search condition input field 231 as operation information. The transmission unit 125d of the work terminal device 125 transmits the operation information to the work management device 123. The receiving unit 123f of the work management device 123 receives the operation information.

[0165] Next, in step S794, the control unit 123d reads work performance information from the storage unit 123e that matches the search conditions included in the operation information received in step S793, and creates an overview of the read work performance information. Then, the control unit 123d creates work confirmation screen information that instructs the work confirmation screen 230 to display the overview of the work performance information.

[0166] Next, in step S795, the transmission unit 123g of the work management device 123 transmits the work confirmation screen information created in step S794 to the work instruction terminal device 125. The receiving unit 125c of the work instruction terminal device 125 receives the work confirmation screen information.

[0167] Next, in step S796, the display processing unit 125a of the work instruction work terminal device 125 displays an overview of the work performance information included in the work confirmation screen information received in step S795 in the work performance history display field 233 of the work confirmation screen 230.

[0168] Next, in step S797, the operation input unit 125b of the work instruction terminal device 125 waits until the detail display button 234 displayed on the work confirmation screen 230 is pressed. When the detail display button 234 is pressed (if the answer in step S797 is YES), the process in step S798 is performed. In step S798, the operation input unit 125b of the work instruction terminal device 125 creates screen call information as operation information, which includes the work performance information selected from the summary of work performance information displayed in the work performance history display field 233. The transmission unit 125d of the work instruction terminal device 125 transmits the operation information to the work management device 123. The receiving unit 123f of the work management device 123 receives the operation information.

[0169] Finally, in step S799, the control unit 123d extracts the product ID and packaging specification code from the work performance information included in the screen call information received in step S798 to create work information. When the processing in step S799 is completed, the processing in step S733 in Figure 7C described above is performed.

[0170] <Summary> As described above, in this embodiment, the work management system displays work guideline images in the work guideline image display field 202 of the work management screen 200 and displays work performance images on the work performance display screen 220. Therefore, for example, work supervisors and on-site workers can easily confirm after the fact (after the work is completed) whether the work was performed appropriately according to the specifications by comparing these images.

[0171] Furthermore, in this embodiment, the work management system uses, as work guide images, an image of the work object after the first work, which is an image of the work object after the first work, and an image of the work object after the second work, which is an image of the work object after the first work. Therefore, on-site workers can refer to the images of the work object after each of the first and second work processes, thereby improving work efficiency. In this embodiment, the work up to the work immediately before the packaging material is attached to the coil C is an example of the first work, and the work from the work onward after the packaging material is attached to the coil C is an example of the second work. In this case, the work management system may switch the display on the display device between the work guide image after the first work and the work guide image after the second work. In this case, the display space for the work guide images after the first and second work processes can be widened, while allowing workers to refer to the work guide images after each process.

[0172] Furthermore, in this embodiment, the work management system uses at least one of the following as work guide images: a 3D work guide image, which is a 3D image based on a three-dimensional model of the work object to be worked on, and a photographic work guide image, which is a photograph of the work object that serves as a sample of the work object's state after work. By using a 3D work guide image as a work guide image, a wide variety of work guide images can be easily created. By using a photographic work guide image as a work guide image, it is possible to create work guide images that would be difficult to display clearly to on-site workers using 3D computer graphics. When both a 3D work guide image and a photographic work guide image are used as work guide images, the work management system may switch between displaying the 3D work guide image and the photographic work guide image on the display device. In this way, the display space for both the 3D work guide image and the photographic work guide image can be increased.

[0173] Furthermore, in this embodiment, the work management system displays work confirmation input information on a display device to allow workers to input confirmation that they have performed a task. Therefore, the work confirmation input information can be used for post-work verification to determine whether or not the work was performed according to the specifications. This also helps to suppress work omissions by on-site workers. In this case, the work management system may display the work guideline image and the work confirmation input information in the same display frame. This improves the readability of the work guideline image and the work confirmation input information. For example, an operator (on-site worker or work supervisor, etc.) can compare the image of the work object after the work is completed (work guideline image) and the work confirmation input information without switching screens. The work confirmation input information may also be information that allows workers to input confirmation for each of multiple confirmation items that they have performed the post-work verification. This allows for more detailed post-work verification to determine whether or not the work was performed according to the specifications. This also helps to further suppress work omissions by on-site workers.

[0174] Furthermore, in this embodiment, if the predetermined work confirmation conditions are met but confirmation input of the work has not been made, the work management system outputs work prompting information, which is information to prompt the on-site worker to confirm that the work has been completed. Therefore, it can prompt the on-site worker to confirm that the work has been completed and, if necessary, prompt the on-site worker to repeat the work.

[0175] Furthermore, in this embodiment, the work management system displays work guide images and work performance images in separate display frames and switches between these display frames. Therefore, for example, it is possible to prevent work performance images that are not used (or are used infrequently) during work from being displayed together with work guide images during work. Thus, for example, it is possible to prevent field workers from confusing work guide images and work performance images during work.

[0176] Furthermore, in this embodiment, the work management system comprises a work management device 123, on-site work terminal devices 124a to 124b, and a work instruction work terminal device 125. Therefore, the work management device 123 can function as a server that provides work guideline images and work performance images. Thus, it is not necessary for each work terminal device to prepare work guideline images and work performance images.

[0177] Furthermore, in this embodiment, the work management system acquires (searches for) work guideline images and work performance images that are stored in association with at least the identification information of the work object, based on work information including the identification information of the work object and the specifications of the work. Therefore, the acquisition (searching) of work guideline images and work performance images can be easily performed. That is, for example, if there is a defect in a work object, the work performance of the work object can be easily confirmed by acquiring (searching for) work guideline images and work performance images based on the identification information of the work object, and it is possible to review whether there were any problems during the work. Specifically, for example, the state of the work object after performing a certain task (such as the first task or the second task) can be confirmed using the work performance image. In this embodiment, an example is given in which the work information includes a product ID and a packaging specification code.

[0178] Furthermore, in this embodiment, the work management system displays terminal images, which are images of the work object taken at the work site, on a display device. By using terminal images and work guideline images, it is possible to more accurately and easily confirm, for example, the condition of detailed parts of the work object and whether the work was performed appropriately according to the specifications.
