Description

Technical Field

[0001] The present invention relates to a management system. More specifically, it relates to a management system for managing work procedure manuals including work information and work instruction images.

Background Art

[0002] Conventionally, at a manufacturing site where mechanical devices are assembled, work procedure manuals including work information and work instruction images have been used. For example, an operator performs the assembly work of a mechanical device while referring to the work procedure manual displayed on the screen of a display device (e.g., a liquid crystal display). The work information and work instruction images included in the work procedure manual are managed on software, and when there is a change, the content of the changed part is confirmed. For example, Patent Document 1 discloses a technique related to the display and editing of an assembly work procedure manual including assembly procedure information for assembly work.

[0003] In the technique described in Patent Document 1, the changed parts of the assembly procedure information were extracted from character information. For example, when a user edited (changed) a work instruction image, the file name of the work instruction image was manually changed, and the presence or absence of the changed part was specified from the change in the file name of the work instruction image.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, according to the technology described in Patent Document 1, when the shape of a component is changed due to a design change of a mechanical device or the like, it is necessary to replace all the work instruction images in which the target component is displayed. When there are a plurality of work instruction images (for example, about 100 to 1000 sheets), it is necessary to change the file name of each work instruction image one by one, which requires a significant amount of man-hours. In addition, since the file name of the work instruction image is manually changed, it is easy to have an omission in changing the file name or an unnecessary change in the file name. If an omission in changing the file name or the like occurs, the editor who edited the work instruction image cannot accurately grasp the changed portion, and there is a risk that the accuracy of the editing will be lacking.

[0006] The present invention has been made in view of such a point, and an object thereof is to provide a management system capable of accurately grasping the presence or absence of a change in a work instruction image.

Means for Solving the Problems

[0007] The management system according to the present invention is a management system that manages a work procedure manual including work information and a work instruction image. The management system includes a storage unit that stores the work procedure manual, an editing unit that edits the work instruction image, an acquisition unit that acquires difference information between an image before editing, which is the work instruction image before editing, and an image after editing, which is the work instruction image after editing, and a presentation unit that presents that there is a change in the work instruction image when the difference information satisfies a predetermined condition.

[0008] According to the management system of the present invention, the acquisition unit acquires difference information between the pre-editing image and the post-editing image edited by the editing unit. That is, the acquisition unit acquires the presence or absence of actual change locations in the work instruction images before and after editing, rather than the presence or absence of changes in character information such as the file name of the work instruction image. Then, when the difference information satisfies a predetermined condition, the presentation unit presents that there is a change in the work instruction image. For example, when there is a large difference between the pre-editing image and the post-editing image, the presentation unit presents that there is a change in the work instruction image. In this way, by comparing the work instruction images before and after editing, the presentation unit can make the administrator and the editor recognize that there are change locations in the work instruction image. Also, since mistakes in changing the file name of the work instruction image do not occur, it is possible to suppress the incorrect recognition of the change locations in the work instruction image and the occurrence of omissions in recognizing the change locations.

Effect of the Invention

[0009] According to the present invention, it is possible to provide a management system capable of accurately grasping the presence or absence of changes in a work instruction image.

[0011] Hereinafter, a management system according to the present embodiment will be described with reference to the drawings. Note that the embodiment described here is, of course, not intended to limit the present invention in particular. Also, the same reference numerals are used for members and parts that perform the same functions, and duplicated descriptions are omitted or simplified as appropriate.

[0012] The management system 10 is a system that manages a work procedure manual including work information and a work instruction image. As shown in FIG. 1, the management system 10 includes a terminal device 30, a server 60, and a router 62. The terminal device 30 and the server 60 are connected in a state in which they can communicate with each other by a wireless communication network constructed through the router 62. The server 60 includes a large-capacity storage device 64 that stores information. In the management system 10 of this embodiment, the terminal device 30 includes a first terminal device 30A used by the manager MA, a second terminal device 30B used by the editor ED, and a third terminal device 30C used by the worker WR. In this embodiment, the number of terminal devices 30 included in the management system 10 is four, but is not limited to this. Here, the manager MA is a person who manages the management system 10 and approves changes to the work procedure manual. The editor ED is a person who edits the work procedure manual. The worker WR is a person who performs assembly work by referring to the work procedure manual. The same person may serve as at least two of the manager MA, the editor ED, and the worker WR. The manager MA and editor ED are, for example, manufacturing process design engineers.

[0013] FIG. 2 is a diagram schematically showing a state in which the work procedure manual 20 is displayed on the display screen 33 of the display device 32. The work procedure manual 20 is used at the manufacturing site. The work procedure manual 20 is displayed on the display device 32 of the third terminal device 30C arranged in front of the worker WR. The worker WR refers to (views) the work procedure manual 20 displayed on the display device 32 and performs the assembly work. As described above, the third terminal device 30C is connected to the server 60, and the latest work procedure manual is displayed on the display device 32 of the third terminal device 30C. However, it is also possible to print the latest work procedure manual stored in the server 60 and hand the printed work procedure manual to the worker WR. As shown in FIG. 2, the work procedure manual 20 includes work information 22 and a work instruction image 25. The work information 22 includes, for example, work No., work name, voltage, component information, tool information, threshold value in the inspection process, program symbol, file name of the work instruction image, and the like. The work information 22 is stored in a text file format such as a CSV file, for example. The work instruction image 25 is a visualization of the work content using characters, symbols, figures (including photos), and the like. The work instruction image 25 is stored in an image file format such as a jpg file, for example. The work procedure manual 20 may include a plurality of work instruction images 25. Note that the work information 22 may be included in the work instruction image 25. In this case, the work information 22 and the work instruction image 25 are stored in, for example, one image file format.

[0014] Next, the configuration of the server 60 will be described in detail. As shown in FIG. 3, the server 60 includes a first storage unit 71, a first transmission / reception unit 73, a first notification unit 75, an update unit 77, and a second notification unit 79. Each of these units may be configured by software. That is, each of the above units may be realized by the server 60 when a computer program is loaded into the server 60. The computer program may be included in a computer-readable recording medium such as a CD or a DVD. The computer program may be downloaded through the Internet. Further, each of the above units may be realized by a processor and / or a circuit configured in the server 60.

[0015] The first storage unit 71 stores the work procedure manual. When the work instruction image of the work procedure manual is updated, the first storage unit 71 stores the work procedure manual including the updated work instruction image. In the present embodiment, the first storage unit 71 is provided in the storage device 64. The first storage unit 71 is an example of the storage unit.

[0016] The first transmission / reception unit 73 transmits and receives the work procedure manual to and from the terminal device 30. More specifically, the first transmission / reception unit 73 transmits the work procedure manual to the terminal device 30. The first transmission / reception unit 73 receives the edited work procedure manual transmitted from the terminal device 30. The first transmission / reception unit 73 transmits the edited work procedure manual to the first terminal device 30A of the administrator MA. The first transmission / reception unit 73 receives an approval signal and a rejection signal, which will be described later, from the first terminal device 30A.

[0017] The first notification unit 75 notifies the administrator MA that there is a change in the work instruction image. For example, when the edited work procedure manual transmitted from the second terminal device 30B of the editor ED is received by the first transmission / reception unit 73 of the server 60, the first notification unit 75 notifies the first terminal device 30A of the administrator MA that there is a change in the work instruction image.

[0018] When the change of the work instruction image is approved by the approval unit 91 (to be described later) of the first terminal device 30A of the administrator MA, the update unit 77 updates the work instruction image stored in the first storage unit 71 to the edited work instruction image. That is, when the first transmission / reception unit 73 receives an approval signal, the update unit 77 updates the work instruction image stored in the first storage unit 71 to the edited work instruction image. When one of the plurality of work instruction images stored in the first storage unit 71 is edited by the editing unit 85 (to be described later), the update unit 77 updates the work instruction image corresponding to the edited work instruction image among all the work instruction images stored in the first storage unit 71 to the edited work instruction image. For example, if the work instruction image to be edited is included in multiple pages of the work procedure manual and the work instruction image included in one page is edited, the update unit 77 also updates the work instruction image corresponding to the edited work instruction image among the work instruction images included in other pages to the edited work instruction image in the same way.

[0019] The second notification unit 79 notifies the editor ED who edited the work instruction image that the change of the work instruction image has been approved. When the first transmission / reception unit 73 receives an approval signal, the second notification unit 79 notifies the second terminal device 30B of the editor ED that the change of the work instruction image has been approved. The second notification unit 79 notifies the editor ED who edited the work instruction image that the change of the work instruction image has been rejected. When the first transmission / reception unit 73 receives a rejection signal, the second notification unit 79 notifies the second terminal device 30B of the editor ED that the change of the work instruction image has been rejected.

[0020] Next, the configuration of the terminal device 30 will be described in detail. As shown in FIG. 3, the terminal device 30 includes a display device 32, an input device 35, a main body case 36 (see FIG. 1), and a control device 80. The display device 32 is, for example, a liquid crystal display or the like. As shown in FIG. 2, the work procedure manual 20 is displayed on the display screen 33 of the display device 32. Examples of the input device 35 include a keyboard, a touch panel, a mouse, and the like. The control device 80 is composed of a microcomputer and is provided inside the main body case 36. The control device 80 includes, for example, a central processing unit (CPU), a ROM that stores programs executed by the CPU, a RAM, and the like. Note that the terminal device 30 of the present embodiment is a desktop personal computer, but may be a notebook personal computer, a tablet terminal, or the like. The first terminal device 30A is arranged in the management area where the administrator MA works. The second terminal device 30B is arranged for each editor ED in the work area where the editor ED works. The third terminal device 30C is arranged for each worker WR in the work area (for example, the manufacturing site) where the worker WR works. Thus, the management system 10 is configured to be simultaneously and parallelly used by a plurality of different administrators MA, editors ED, and workers WR in a plurality of separate work areas.

[0021] As shown in FIG. 3, the control device 80 of the first terminal device 30A includes a second storage unit 81, a second transmission / reception unit 83, an editing unit 85, an acquisition unit 87, a presentation unit 89, an approval unit 91, and a rejection unit 93. The control device 80 of the second terminal device 30B includes a second storage unit 81, a second transmission / reception unit 83, an editing unit 85, an acquisition unit 87, and a presentation unit 89. Thus, the second terminal device 30B used by the editor ED does not include the approval unit 91 and the rejection unit 93. Further, the control device 80 of the third terminal device 30C includes a reception unit 97 that receives the latest work procedure manual transmitted from the server 60. The functions of each part of the control device 80 are realized by a program. This program is read from a recording medium such as a CD or a DVD, for example. Note that this program may be downloaded through the Internet. Also, the functions of each part of the control device 80 may be realized by a processor and / or a circuit or the like.

[0022] The second storage unit 81 temporarily stores the work procedure manual transmitted from the server 60. When the work instruction image of the work procedure manual is edited by the editing unit 85, the second storage unit 81 temporarily stores the work procedure manual including the edited work instruction image.

[0023] The second transmission / reception unit 83 transmits and receives the work procedure manual to and from the server 60. More specifically, the second transmission / reception unit 83 receives the work procedure manual transmitted from the server 60. The second transmission / reception unit 83 transmits the edited work procedure manual to the server 60. The second transmission / reception unit 83 of the first terminal device 30A transmits an approval signal and a rejection signal, which will be described later, to the server 60.

[0024] The editing unit 85 edits the work instruction image of the work procedure manual. The editing unit 85 edits, for example, the characters, symbols, and graphics displayed in the work instruction image. The editing unit 85 edits, for example, the part graphic PA shown in FIG. 4A to the part graphic PB shown in FIG. 4B in the work instruction image 25. The editing of the work instruction image is edited, for example, by a computer-aided design device (CAD device). The editing unit 85 is provided in each of the first terminal device 30A of the administrator MA and the second terminal device 30B of the editor ED, and both the administrator MA and the editor ED can edit the work instruction image of the work procedure manual. When the editor ED edits the work instruction image, the edited content is not reflected without the approval of the administrator MA.

[0025] The acquisition unit 87 acquires the changes between the work procedure manual before editing and the work procedure manual after editing. The acquisition unit 87 acquires the difference information between the pre-editing image 25A (see FIG. 5A), which is the work instruction image before editing, and the post-editing image 25B (see FIG. 5B), which is the work instruction image after editing. The acquisition unit 87 acquires, for example, the difference file size as the difference information based on the file size of the pre-editing image and the file size of the post-editing image. The acquisition unit 87 may acquire the number of pixel changes as the difference information based on the pixel value of each pixel of the pre-editing image and the pixel value of each pixel of the post-editing image. The pixel value of the pre-editing pixel and the pixel value of the post-editing pixel are compared between the corresponding matrices.

[0026] When the difference information acquired by the acquisition unit 87 satisfies a predetermined condition, the notification unit 89 notifies that there is a change in the work instruction image. The notification unit 89 notifies, for example, that there is a change in the work instruction image on the display screen 33 of the display device 32 of the terminal device 30. The notification unit 89 notifies that there is a change in the work instruction image when the difference file size is equal to or greater than a predetermined value (for example, 1000 B or more). The notification unit 89 may notify that there is a change in the work instruction image when the number of pixel changes is equal to or greater than a predetermined ratio (for example, 1% or more of the total number of pixels). As shown in FIG. 6, the notification unit 89 displays a table 40 in which work information is associated with file information (for example, file name) of the work instruction image on the display screen 33 of the display device 32 of the terminal device 30. In FIG. 6, “edit_old” indicates a part of the work procedure manual before editing, “edit_new” indicates a part of the work procedure manual after editing, and as shown by the hatching in the column of Work Diagram 1(R) in Table 40, by changing the part shape PA of the part shown in FIG. 4A to the part shape PB of the part shown in FIG. 4B, it shows that there are changes in the work instruction image 25 in three parts of the work procedure manual. The notification unit 89 highlights the file information of the changed work instruction image in the table 40. That is, the notification unit 89 visualizes the changed part by using the table 40. Thereby, the administrator MA and the editor ED can easily recognize which part of the work procedure manual has been changed.

[0027] The approval unit 91 approves the change of the work instruction image. The approval unit 91 approves the change of the work instruction image when a virtual approval button displayed on the display screen 33 of the display device 32 is pressed. The approval unit 91 is provided only in the first terminal device 30A of the administrator MA. That is, although both the administrator MA and the editor ED can edit the work instruction image, only the administrator MA can approve the change of the work instruction image. When the change of the work instruction image is approved by the approval unit 91, the second transmission / reception unit 83 of the first terminal device 30A transmits an approval signal to the server 60.

[0028] The rejection unit 93 rejects the change of the work instruction image. The rejection unit 93 rejects the change of the work instruction image when a virtual rejection button displayed on the display screen 33 of the display device 32 is pressed. The rejection unit 93 is provided only in the first terminal device 30A of the administrator MA. That is, when the work instruction image is edited by the editor ED, if the edit is inappropriate, the administrator MA can reject the change. When the change of the work instruction image is rejected by the rejection unit 93, the second transmission / reception unit 83 of the first terminal device 30A transmits a rejection signal to the server 60. After the rejection signal is transmitted to the server 60, the rejection signal is transmitted from the second notification unit 79 of the server 60 to the second terminal device 30B of the editor ED, and it is notified that the change has been rejected.

[0029] Next, the procedure for editing the work procedure manual will be described. FIG. 7 is a flowchart showing the procedure for editing the work procedure manual. Here, the case where the editor ED edits the work procedure manual using the second terminal device 30B will be described as an example.

[0030] In step S10, the editor ED downloads the work procedure manual to be edited from the server 60 to the second terminal device 30B. The work procedure manual is temporarily stored in the second storage unit 81 of the second terminal device 30B. When one editor ED downloads the work procedure manual for the purpose of editing, until the editing of the downloaded work procedure manual is completed (for example, until the change of the work procedure manual is approved or rejected by the administrator MA), other editors ED and the administrator MA cannot download the work procedure manual being edited. That is, a plurality of editors ED and the administrator MA cannot edit the same work procedure manual at the same time.

[0031] In step S20, the editor ED edits the work instruction image of the work procedure manual using the second terminal device 30B. That is, the work procedure manual is edited by the editing unit 85 of the second terminal device 30B. The edited work procedure manual is temporarily stored in the second storage unit 81 of the second terminal device 30B separately from the work procedure manual before editing.

[0032] In step S30, the acquisition unit 87 of the second terminal device 30B acquires the changes between the pre-editing work procedure manual and the post-editing work procedure manual. The acquisition unit 87 acquires, for example, the difference file size as difference information based on the file size of the pre-editing image and the file size of the post-editing image.

[0033] In step S40, when the difference file size is equal to or greater than a predetermined value, the presentation unit 89 presents that there is a change in the work instruction image. The presentation unit 89 highlights the file information of the changed work instruction image in the table 40 displayed on the display screen 33 of the display device 32 of the second terminal device 30B. Thereby, the editor ED can confirm the changed part of the work procedure manual.

[0034] In step S50, the editor ED uploads the work procedure manual edited on the second terminal device 30B to the server 60. Thereby, the post-editing work procedure manual temporarily stored in the second storage unit 81 of the second terminal device 30B is deleted.

[0035] In step S60, when the first transmission / reception unit 73 of the server 60 receives the post-editing work procedure manual transmitted (uploaded) from the second terminal device 30B, it transmits the post-editing work procedure manual to the first terminal device 30A of the administrator MA, and the first notification unit 75 notifies the administrator MA that there is a change in the work instruction image. Then, the administrator MA checks the content of the post-editing work procedure manual and approves the change. At this time, the presentation unit 89 of the first terminal device 30A highlights the file information of the changed work instruction image in the table 40 displayed on the display screen 33 of the display device 32 of the first terminal device 30A. Then, when the change in the work instruction image is approved by the approval unit 91, the second transmission / reception unit 83 of the first terminal device 30A transmits an approval signal to the server 60. After the approval signal is transmitted to the server 60, an approval signal may be transmitted from the second notification unit 79 of the server 60 to the second terminal device 30B of the editor ED to notify that the approval has been made (or the update of the work procedure manual has been completed).

[0036] In step S70, when the approval unit 91 approves the change of the work instruction image, the update unit 77 updates the work instruction image stored in the first storage unit 71 to the edited work instruction image. In this way, the work procedure manual is edited and updated.

[0037] As described above, according to the management system 10 of the present embodiment, the acquisition unit 87 acquires the difference information between the pre-editing image and the post-editing image edited by the editing unit 85. That is, the acquisition unit 87 acquires the presence or absence of the actual changed portions of the work instruction images before and after editing, rather than the presence or absence of changes in character information such as the file name of the work instruction image. Then, when the difference information satisfies a predetermined condition, the presentation unit 89 presents that there is a change in the work instruction image. For example, when there is a large difference between the pre-editing image and the post-editing image, the presentation unit 89 presents that there is a change in the work instruction image. In this way, by comparing the work instruction images before and after editing, the presentation unit 89 can make the administrator MA and the editor ED recognize that there are changed portions in the work instruction image. Also, since mistakes in changing the file name of the work instruction image do not occur, it is possible to suppress the incorrect recognition of the changed portions of the work instruction image and the omission of the recognition of the changed portions.

[0038] According to the management system 10 of the present embodiment, the acquisition unit 87 acquires the difference file size as the difference information based on the file size of the pre-editing image and the file size of the post-editing image, and when the difference file size is equal to or greater than a predetermined value, the presentation unit 89 presents that there is a change in the work instruction image. In this way, by comparing the file sizes of the work instruction image before and after editing, the acquisition unit 87 can easily and quickly acquire the difference information.

[0039] According to the management system 10 of this embodiment, the acquisition unit 87 acquires the number of pixel changes as difference information based on the pixel values for each pixel of the pre-editing image and the pixel values for each pixel of the post-editing image, and the presentation unit 89 may present that there is a change in the work instruction image when the number of pixel changes is equal to or greater than a predetermined value. In this way, by comparing the pixel values of the pixels before and after editing the work instruction image, the acquisition unit 87 can acquire more accurate difference information.

[0040] According to the management system 10 of this embodiment, the presentation unit 89 displays the table 40 in which the work information and the file information of the work instruction image are associated on the display screen 33 of the display device 32, and highlights the file information of the changed work instruction image in the table 40. Thereby, the administrator MA and the editor ED can more clearly recognize that there is a change in the work instruction image.

[0041] The management system 10 of this embodiment includes a first notification unit 75 that notifies the administrator MA that there is a change in the work instruction image, an approval unit 91 that approves the change of the work instruction image, and an update unit 77 that updates the work instruction image stored in the first storage unit 71 to the post-editing work instruction image when the change of the work instruction image is approved by the approval unit 91. In this way, when the work instruction image is edited, the check of the administrator MA is required, so that it is possible to suppress the edited work instruction image from being erroneously updated.

[0042] According to the management system 10 of this embodiment, the work procedure manual includes a plurality of work instruction images, and when one of the plurality of work instruction images stored in the first storage unit 71 is edited by the editing unit 85, the update unit 77 updates the work instruction image corresponding to the edited work instruction image among all the work instruction images stored in the first storage unit 71 to the post-editing work instruction image. In this way, when one of the work instruction images is edited, the update unit 77 automatically updates the work instruction image corresponding to the edited work instruction image to the post-editing work instruction image, so that it is possible to suppress the occurrence of omission or mistake in the change of the work instruction image.

[0043] The management system 10 of this embodiment includes a rejection unit 93 that rejects changes to the work instruction image, and a second notification unit 79 that notifies the editor ED who edited the work instruction image that the change to the work instruction image has been rejected. As a result, the editor ED who edited the work instruction image can recognize that the editing of the work instruction image has been rejected.

[0044] As described above, the preferred embodiments of the present invention have been described. However, each of the above-described embodiments is merely an example, and the present invention can be implemented in various other forms.
