Description

Technical Field

[0001] The present invention relates to a work assisting system for assisting a worker in his work. Background Art

[0002] In recent years, the digitization of work sites has accelerated, and the use of portable terminals for inputting work information has become popular. In addition, the use of electronic shelf signs and electronic labels (hereinafter referred to as "labels") to replace paper is developing in addition to paperless management of product information and traceability. When using labels to manage products, it is necessary to pre-register product and label information (such as unique numbers) and other related information in the database.

[0003] Regarding Patent Document 1, the identifier corresponding to the unit (product) and the identifier of the inspection table are registered in a database, and the read identifier of the unit and the identifier of the inspection table are compared with the database to display whether they match or not. In addition, in the case of a mismatch, the correct inspection table name is displayed.

[0004] Prior art literature

[0005] Patent Document 1: Japanese Patent Application Publication No. 2018-018371 Summary of the invention

[0006] Problems to be solved by the invention

[0007] In the past, products were associated with labels at a specific location, such as a place on a production line, and the labels were installed on the products. However, at the work site, products are scattered in a wide area. Therefore, if products are associated with labels at a specific location in advance, time is required to find the product corresponding to the label and to affix it while visually comparing the label and the product. In addition, since human-based installation work is required, if the number is large, installation differences may occur. Therefore, in consideration of operability and reliability, it is preferred to correctly associate products with labels using a portable terminal before the products are produced. When a portable terminal is used for association, it is possible to shorten the comparison time between products and labels and prevent installation differences. However, in order to correctly associate products with labels, a structure is required so that operators using the portable terminal will not mistakenly input label information and product names. Patent document 1 assumes that products and labels are associated in advance, and may not have conducted sufficient research on preventing mis-input.

[0008] The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a structure in which an operator does not make an erroneous input when associating a product with a tag using a mobile terminal.

[0009] Means for solving problems

[0010] The work support system of the present invention supports the work of associating information recording media with products, and sends registration data describing a list of information recording media not associated with products on a server to a portable terminal together with medium-specific information of the information recording media.

[0011] Effects of the Invention

[0012] According to the work support system of the present invention, the product and the label are correctly associated with high work efficiency by preventing the operator from inputting errors using the portable terminal. Other problems, structures, advantages, etc. of the present invention will become clear through the following description of the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] <Implementation method 1>

[0033] Figure 1 This is a diagram showing the relationship between a label and a product. A label 11 is attached to a product 10. An operator associates the label 11 with the product 10 before the product 10. The label 11 is used to manage the information of the product 10, and the information stored in the label is read and acquired by a portable terminal 12 (described later). If the label 11 has a display function, the status of the product 10 can also be known at a glance by displaying the information of the product 10.

[0034] Figure 2 1 is a diagram showing the structure of a work assisting system according to Embodiment 1 of the present invention. The work assisting system includes a product 10, a tag 11, a portable terminal 12, a server 20, and a PC (Personal Computer) 30. The server 20 includes an association determination unit 21, a registration data generation unit 22, a transmission information control unit 23, and a database 24. These operations will be described later.

[0035] Figure 3 This is a flowchart for explaining the operation of the work support system. Figure 3 The following describes each step.

[0036] Step S2000: The operator uses the portable terminal 12 to read the tag inherent information (medium inherent information) of the tag 11. For example, the inherent tag ID or the like held inside the tag 11 is equivalent to this. The information is read, for example, by using the NFC (Near Field Communication) function of the portable terminal 12 to approach the tag 11. If the portable terminal 12 and the tag 11 have functions such as Bluetooth or Wifi, the wireless function may also be used.

[0037] Step S2001 : The mobile terminal 12 sends the tag-specific information and the terminal-specific information to the association determination unit 21 in the server 20 .

[0038] Step S2002: The association determination unit 21 determines whether the tag unique information acquired from the tag 11 is associated with the product 10 in the database 24. The association determination unit 21 outputs the determination result to the registration data generation unit 22 and the transmission information control unit 23.

[0039] Step S2004: When receiving a determination result indicating that there is no association from the association determination unit 21, the registration data generation unit 22 generates a registration file 100. The registration file 100 can be used as a registration form used when associating the tag 11 with the product 10 in the portable terminal 12. The registration file 100 describes a list of combinations of (a) tag-specific information and (b) products 10 that are not associated with the tag 11 in the database 24. A specific example will be described later.

[0040] Step S2005: Based on the determination result of the association determination unit 21, the transmission information control unit 23 controls whether to transmit the registration file 100 generated by the registration data generation unit 22 to the portable terminal 12. When receiving a determination result indicating that there is no association from the association determination unit 21, the transmission information control unit 23 transmits the registration file 100 to the portable terminal 12 corresponding to the terminal-specific information.

[0041] Step S2006 : When receiving the determination result indicating that there is an association from the association determination unit 21 , the transmission information control unit 23 notifies the portable terminal 12 that the tag 11 and the product 10 are associated.

[0042] By sending the registration file 100 to the portable terminal 12 corresponding to the terminal-specific information through the above operation, the product 10 and the label 11 can be correctly associated. The PC 30 can access the server 20 and confirm the label-specific information and the product name-associated information in the database 24.

[0043] Figure 4This is an example of a screen in which the portable terminal 12 displays the registration file 100. The registration file 100 has a label-specific information display unit 101 and a product name selection unit 102. The label-specific information display unit 101 displays the information read by the portable terminal 12, thereby preventing the operator from making an erroneous input due to manual input. The product name selection unit 102 displays a list of products 10 in the database 24 that are not associated with the label 11. Figure 4 Such a form that can be selected by a pull-down menu may also be a form in which selection is made from a list display like a list box. When the operator presses the send button 103, the portable terminal 12 sends the product name of the selected product 10 together with the inherent information of the label 11 to the server 20. The server 20 associates them and stores them in the database 24. This processing may be performed by any functional unit on the server 20.

[0044] Figure 5 This is a table showing data stored in the database 24. The database 24 stores tag-specific information of the tag 11, the product name of the product 10, and the terminal-specific information of the portable terminal 12 that accesses the tag 11. Record #1 indicates that IDm01 is associated with the product 01, and the portable terminal 12 corresponding to the terminal-specific information device 01 is the latest portable terminal that has accessed the tag 11 corresponding to IDm01. Record #5 indicates that the product 10 and the tag 11 are not yet associated, and the product 03 is stored as the product name selection unit 102 of the registration file 100.

[0045] Figure 6 1 is a diagram showing an example of notification to the portable terminal 12 when the tag 11 is associated with the product 10. In S2006, the portable terminal 12 displays the association notification screen 190. The association notification screen 190 displays a mark indicating that the tag and the product have been associated (e.g., a message to that effect), the tag inherent information to be registered, and the product name associated with the tag inherent information stored in the database 24.

[0046] <Implementation 1: Summary>

[0047] The work support system of the first embodiment uses the tag inherent information read from the tag 11 by the portable terminal 12 as a keyword, obtains a list of products 10 that are not associated with the tag 11, and sends the list (as a registration file 100) to the portable terminal 12. The user of the portable terminal 12 selects any one of the products 10 in the list and replies. As a result, for example, a product 10 that has been associated with any tag 11 will not be mistakenly associated with other tags 11, so the product 10 and the tag 11 can be correctly associated. In addition, when the product 10 and the tag 11 are already associated, it is possible to prompt this fact on the portable terminal 12.

[0048] <Implementation method 2>

[0049] Figure 7 1 is a diagram showing the structure of the work assisting system of the second embodiment of the present invention. The difference from the first embodiment is that a registration data generation determination unit 25 is added, and the operator information is sent from the portable terminal 12 in addition to the tag inherent information and the terminal inherent information. According to the present embodiment, the operators who can register the association between the tag 11 and the product 10 are limited, and the association between the tag 11 and the product 10 performed by an unspecified number of portable terminals 12 can be avoided from being mistakenly registered. The other actions are the same as those of the first embodiment, so the following mainly describes the actions of the registration data generation determination unit 25.

[0050] The registration data generation determination unit 25 receives operator information (e.g., operator ID described later) from the portable terminal 12, and determines whether the operator has the authority to register the association between the tag 11 and the product 10 based on the operator information. If the operator has the authority, the registration data generation unit 22 is notified that the registration file 100 is allowed to be generated. If the operator does not have the authority, the registration data generation unit 22 and the transmission information control unit 23 are notified that the registration file 100 is not allowed to be generated. The registration data generation unit 22 generates or does not generate the registration file 100 according to these notifications.

[0051] Figure 8 It is a table showing the relationship between the login information and the terminal inherent information. This table can be stored in the database 24. Figure 8 In addition to Figure 5 In addition to the label inherent information and product name, the correspondence between the terminal inherent number of the logged-in portable terminal 12 and the operator information input to the user name input unit 200 described later is implemented. For example, in record #1, it can be seen that the operator information worker A is working (logged in to the server 20) using the terminal inherent information device 01.

[0052] Fig. 9 is a table showing registrants who have the authority to register the association between product 10 and label 11. This table can be stored in database 24. According to record #1, it can be known that the registrant who has the login authority for product 01 is staff member A. The registration data generation determination unit 25 generates a registration data based on the registration data. Fig. 9 registrants and Figure 8 The operator information is used to determine whether to generate the registration file 100. For example, Figure 8 "Operator Information" of the Fig. 9 The table determines whether the operator has the associated permissions.

[0053] Fig.10 2 is a diagram showing an example of notification to an operator who does not have the registration authority for the tag 11. When receiving a notification from the registration data generation determination unit 25 that the operator does not have the associated registration authority, the transmission information control unit 23 notifies the portable terminal 12 of the notification. When receiving a notification from the transmission information control unit 23 that the operator does not have the registration authority for the tag 11, the portable terminal 12 displays a warning display 202. The warning display 202 is a pop-up window display, and the pop-up window can be closed by pressing the OK button. Fig.10 This is just an example, and any other method is also possible as long as the same content as the warning display 202 is conveyed to the operator.

[0054] Fig.11 1 is a diagram showing a screen for recording operator information on the portable terminal 12. This screen is used to record the operator ID in the portable terminal 12 (or on the server 20), and is used, for example, when the operator starts using the portable terminal 12 (or starts an association operation). The portable terminal 12 is provided with a user name input unit 200 and an OK button 201. The operator displays the user name registration screen through menu transition on the portable terminal 12. The operator inputs his or her own name or an ID associated with the name into the user name input unit 200, and presses the OK button 201. After pressing, the information is saved in the portable terminal 12.

[0055] After the ID is saved, when the operator uses the portable terminal 12 to read the tag inherent information of the tag 11, the value input to the user name input unit 200 is read from the storage area of ​​the portable terminal 12 and sent to the server 20. The user name or ID serves as a login ID for the server 20. The login ID is associated with the terminal inherent information and stored in the database 24. As a result, when the portable terminal 12 logs in to the server 20, it is only necessary to send the tag information and the terminal inherent information to the server 20, so it is not necessary to send the operator ID every time the server 20 is accessed. Here, an example in which the operator information is saved in the portable terminal 12 is shown, but it can also be sent to the database 24 in the server 20 as login information.

[0056] When receiving the login information (ID of the operator, etc.) from the portable terminal 12, the registration data generation determination unit 25 uses the login information to query Fig. 9 If the ID is recorded as a person with registration authority, the registration data generation determination unit 25 determines that the person has the authority to register the association between the product 10 and the tag 11, and sends the registration file 100 to the portable terminal 12. If the ID is not recorded, the information transmission control unit 23 notifies the person of the authority, and the portable terminal 12 displays Fig.10 screen.

[0057] <Implementation method 3>

[0058] Fig.12 1 is a diagram showing the structure of a work assisting system according to a third embodiment of the present invention. The difference from the first embodiment is that a registration data analyzing unit 26 is added. In the first embodiment, the portable terminal 12 is Figure 4 In the above description, the registration file 100 is displayed on the screen and the selection result on the screen is sent to the server 20. In the third embodiment, the selection result is recorded in the registration file 100 itself, and the registration file 100 is sent to the server 20. According to the present embodiment, the tag inherent information and the product name can be registered in the database 24 using the registration file 100 itself. Since the other operations are the same as those in the first embodiment, the operation of the registration data analysis unit 26 will be mainly described below.

[0059] The registration data analysis unit 26 receives the registration file 100 from the portable terminal 12. Figure 4 As shown, the received registration file 100 includes a label-specific information display unit 101 and a product name selection unit 102. The registration data analysis unit 26 extracts the label-specific information in the label-specific information display unit 101 in the registration file 100 and the product name in the product name selection unit 102 selected in a pull-down form, and registers the label-specific information with the corresponding product name in the database 24 (i.e., performs association).

[0060] Fig.13 is a table showing the storage information of the database 24 after the tag-specific information is added. This table can be stored in the database 24. Figure 5 In the record #5, the tag unique information is blank for the product name product 03, which means that the product is not associated. The registration data analysis unit 26 registers the tag unique information IDm03 in the record #5, thereby completing the association.

[0061] When the registration to the database 24 is completed, the registration data analysis unit 26 outputs the tag-specific information, product name, and operator information to the transmission information control unit 23. The transmission information control unit 23 generates transmission information based on the information received from the registration data analysis unit 26 and transmits it to the portable terminal 12. In order to make the operator realize that the registration is completed normally, the tag-specific information and product name are displayed on the portable terminal 12. Fig.14 A specific example of display is described in FIG.

[0062] Fig.142 is a diagram showing a screen for confirming the association between the tag inherent information and the product name. The information transmission control unit 23 transmits the association result (a pair of tag inherent information / product name / operator information) stored in the database 24 by the registration data analysis unit 26 to the portable terminal 12. The portable terminal 12 displays the information on the associated information confirmation screen 203. The associated information confirmation screen 203 may include an OK button for closing the notification. In addition to the tag inherent information and the product name, the operator information may be added to the display so that it is known who has registered.

[0063] Fig.15 2 is a diagram showing a screen for instructing information writing to the tag 11. The association information between the tag 11 and the product 10 on the server 20 can also be recorded on the tag 11. In this case, after the registration data analysis unit 26 stores the association result in the database 24, a notification urging the portable terminal 12 to record the same information on the tag 11 is sent from the information transmission control unit 23. After receiving the notification, the portable terminal 12 displays a tag rewrite instruction screen 204. Through this screen, the operator is instructed to write information to the tag 11. The tag rewrite instruction screen 204 is configured with a write button. When the operator presses the write button, the portable terminal 12 becomes in a state where it can write to the tag 11. When the operator presses the write button, the portable terminal 12 converts the tag inherent information, product name, and operator information received from the information transmission control unit 23 into a format to be written to the tag 11. The operator brings the portable terminal 12 close to the tag 11, and the portable terminal 12 writes this information to the tag 11, for example, through short-range communication.

[0064] Fig.16 This is an example of a screen displaying information written to the label 11 by the portable terminal 12 on the label 11. In addition to the product name, label inherent information, and operator information, the label 11 can also display the date and time of the registered operation. By setting it as such a display, it is possible to understand that the label 11 and the product 10 are correctly associated at the correct timing. That is, the operator cannot directly observe the associated information on the database 24, but by displaying the same information on the label 11, the operator can confirm that it is correctly associated on the server 20. In this way, the correct association between the label 11 and the product 10 can be confirmed through various paths.

[0065] In the third embodiment, the portable terminal 12 can directly send the registration file 100 as a data file to the server 20. Therefore, there is no need to prepare a registration form or the like on the portable terminal 12, and the registration file 100 itself can be used as a registration form.

[0066] <Implementation method 4>

[0067] Fig.17This is a diagram showing a screen for instructing to send the information to the server 20 after writing to the tag 11. The server sending instruction screen 205 is displayed on the portable terminal 12. The instruction to send information to the server 20 is displayed in the server sending instruction screen 205. In addition, a send button for sending to the server 20 is configured. After confirming the instruction, the operator presses the send button. The portable terminal 12 sends the information written to the tag 11 to the server 20. In this way, after the display of the tag 11 is rewritten, the displayed information and whether the operation is performed correctly can be managed on the server 20.

[0068] Fig.18 1 is a diagram showing the configuration of a work support system according to a fourth embodiment of the present invention. In addition to the configuration described in the third embodiment, a label display information registration unit 27 is added. The label display information registration unit 27 receives information received from the portable terminal 12 via Fig.17 The label display information sent from the screen is registered in a table corresponding to the corresponding label inherent information in the database 24. The other structures are the same as those in the first embodiment.

[0069] Fig.19 This is a table showing information stored in the database 24 including label display information. The label display information corresponding to each label 11 is stored in the database 24. By checking the database 24, it is possible to check whether the operation of associating the label 11 with the product 10 is correctly completed. For example, according to record #2, it can be seen that the operation of sending the label display information to the server 20 is not performed.

[0070] When the portable terminal 12 writes information to the tag 11, the portable terminal 12 may determine whether the writing is completed normally. Fig.17 A message to that effect is displayed if the process does not end normally.

[0071] <Variations of the present invention>

[0072] The present invention is not limited to the above-mentioned embodiments, and includes various modified examples. For example, within the scope of the main purpose of the invention, a part of the structure of a certain embodiment can be replaced with the structure of another embodiment, and the structure of another embodiment can be added to the structure of a certain embodiment. In addition, with respect to a part of the structure of each embodiment, other structures can be added, deleted, or replaced.

[0073] In the above embodiment, various equipment installed at a work site are cited as typical examples of the product 10 , but the present invention is not limited thereto, and any equipment can be assumed as the product 10 .

[0074] In the above embodiment, the registration file 100 can be configured to have, for example, Figure 4Alternatively, instead of the registration file 100, data in any format including at least the label-specific information and the product list may be used as the registration data, similarly to the registration file 100. When the registration data is displayed on the portable terminal 12, if the registration data itself does not have an input form, the portable terminal 12 may generate a PDF file corresponding to the registration data. Figure 4 Same picture.

[0075] In the above embodiment, the case where the tag 11 is mounted on the product 10 is described, but any other detachable information recording medium may be mounted on the product 10 instead of the tag 11 or in combination with the tag 11 to perform the same operation as in the above embodiment.

[0076] In the above embodiment, each functional unit (association determination unit 21, registration data generation unit 22, transmission information control unit 23, registration data generation determination unit 25, registration data analysis unit 26, label display information registration unit 27) of the server 20 can be composed of hardware such as circuit devices equipped with these functions, or can be composed by executing software equipped with these functions by a computing device such as a CPU (Central Processing Unit). The database 24 can be composed by storing data recorded in a storage device.
