Description

  The present invention relates to a work support system, an IC tag for work support system, and a portable information terminal for work support system.

  In recent years, RFID (Radio Frequency Identification) technology for recognizing an article using an IC tag has attracted attention (see, for example, Patent Document 1). For example, IT is rapidly progressing in work sites such as factory sites, construction sites, and agricultural sites, and the introduction of the RFID technology is also progressing in these sites. For example, in a factory, parts are conveyed by a belt conveyor, a carriage, or the like, and a plurality of parts are assembled in many processes and commercialized. Here, by attaching an IC tag to each part, it is possible to identify and manage the assembled product based on the parts used in the respective steps.

  When performing the above identification, management, etc., the IC tag attached to the component is stored in the IC tag by operating a personal digital assistant (PDA: Personal Data Assistant) in each step. It is necessary to perform operations such as reading the component information and associating the newly assembled product information with the component information. In addition, after updating the product information, an operation of transmitting the product information to a server is also necessary. As described above, as IT and ICT (Information and Communications Technology) become popular, information input and information reference at work sites are required.

  However, it is difficult for a field worker to master the PDA at the work site. Even if the operation of the PDA itself is not complicated, at work sites where many on-site workers take turns or the daily work changes, Each time the work content changes, it is necessary to individually recognize the PDA operation method according to the work process performed by each field worker. Also, depending on the work site, it may be difficult to connect to the server.

  Hereinafter, the work support system, the IC tag for the work support system, and the portable information terminal for the work support system of the present invention will be described in detail. However, the present invention is not limited to the following embodiments.

(Embodiment 1)
The flowchart of FIG. 1 shows an example of the basic processing flow of the work support system of the present invention. For example, a case where the worker a performs work related to the construction site A will be described. As shown in the figure, the worker a turns on the power of the PDA having the IC tag reader (S1), and the IC tag for the A environment in which the operating environment data of the construction site A is stored by the IC tag reader (IC for operating environment) Tag) is read (S2). In the IC tag for the operating environment, for example, the system variable initial value and the execution program according to the construction site A are written. The variable initial value may include a definition of a display area and a coordinate system. Examples of the execution program include a method for placing building materials, a program in accordance with a work floor on the site, a storage destination of a photograph taken by a camera, a program for processing image conversion and additional information, and the like. Next, the IC tag reader (IC tag for worker identification) is read by the IC tag reader (S3). The worker identification IC tag stores, for example, system variable initial values and execution programs that match the characteristics and preferences of the worker a. For example, in the case of an operator having color vision abnormality, the display color on the PDA screen can be set avoiding a combination of colors that are difficult to identify. In this way, by storing worker-specific data in the worker identification IC tag in advance, the worker can read the worker identification IC tag with the PDA and make the PDA suitable for himself. Can be set in the operating environment. Therefore, the system can be adapted to the concept of universal design. Then, the PDA that has read the data in the steps S2 and S3 performs an initialization process for setting variable initial values with reference to the data (S4). In the initialization process S4, the execution programs may be stored in a character string type variable or the like in order to execute the execution programs at high speed by an interpreter method. When the initialization process S4 is completed, the PDA screen displays a layout diagram of the location at the construction site A and a menu of work contents to be performed by the worker a in a state suitable for the worker a. a performs work and PDA operation according to the menu (location operation (S5)).

  FIG. 2A is an explanatory diagram showing an example of the operation in the work support system of the present invention. Also, FIG. 2B shows an explanatory diagram of an example of the operation in the case where the same operation is performed in a system not according to the present invention, in comparison with FIG. Here, an example of location management in a state where a building material, which is a product, is manufactured at a manufacturing factory, the manufactured product is moved to a pre-shipment product storage area, and is waiting for shipment. In the case where an operator performs work for shipping a specific product in accordance with the display on the PDA screen, the system not according to the present invention performs the following operation as shown in FIG. That is, on the PDA screen possessed by the worker, work menu selection screens such as “building material arrangement”, “movement”, “shipment” and the like are displayed in the first stage. Therefore, when the “shipment” menu is selected, the layout of the entire site is displayed. Next, in order to specify the target product, the “enlarge” menu is selected, and on the enlargement operation screen, a place to be enlarged is selected and an enlargement instruction is given. The place to be enlarged is displayed in an enlarged manner, and the target product can be specified for the first time. On the other hand, in the work support system of the present invention, as shown in FIG. First, an operator reads an IC tag storing an initial value of a specific shipping destination and an execution program with an IC tag reader attached to the PDA. As the initial value, an easy-to-understand display area and a coordinate system are defined for each specific shipping destination. FIG. 3 shows a conceptual diagram of the product storage area before shipment as seen from above. For example, when a product for a specific shipping destination is arranged at a location with a hatched line, the origin (0, 0) of the (x, y) coordinate system is defined in the vicinity of the shaded area. Further, a width corresponding to the size of the shaded area is defined as a display area. After reading the IC tag, on the PDA screen possessed by the operator, a work menu selection screen such as “building material placement”, “movement”, “shipment”, etc. is displayed in the first stage. Therefore, when the “Shipment” menu is selected, the layout of the site where the place where the product for a specific shipping destination is placed is enlarged and displayed in an appropriate size is displayed, and the target product can be immediately identified. . The IC tag for each shipping destination includes, for example, shipping destination data, location origin, location x-axis and y-axis and their widths, initial values of variables at the time of PDA start-up (start-up of shipping destination unit), PDA start-up (shipment Start unit) execution program, initial value of the variable when placing the product, execution program when placing the product, initial value of the variable when moving, execution program when moving, initial value of the variable at the time of shipment, execution at the time of shipment Programs, product storage layout diagrams, product information, and the like can be stored.

  FIG. 4 is a diagram showing an execution example of the execution program stored in the IC tag in the present invention. A black star indicates a variable initial value or an execution program written in the IC tag. In the initial variable value setting in the initialization process S4, variable initial values a1, a2, a3, etc. are set in the IC tag data for environment A or the IC tag data for worker a read in step S2 or S3. It is determined whether or not there is (if). If there is the setting, the read variable initial value is set as the environment initial value. If the read IC tag data does not include the variable initial values a1, a2, a3, etc. (else), the system default value is set as the environment initial value, and the process ends (end). Subsequently, the operation enters the location operation S5 (Loop). In the location operation S5, it is determined whether there is building material display information in the read IC tag data (if). If there is the building material display information, the building material is displayed on the screen. Data necessary for the screen display is stored in the IC tag. If there is no building material display information in the read data (else), the loop exits and the execution program ends (end). For example, when a product to be shipped on the day of activation is displayed in red, data of “variable initial value (color) = red” is set in the IC tag. Then, the data is set as the environmental initial value. The execution program determines whether or not they match in the estimated shipping date comparison (if). If there is a product whose shipping date matches, that product is displayed in red. If there is no matching product (else), the execution program ends (end). In the example of FIG. 2A, when there is a building material to be shipped, a display for specifying the location of the target building material is displayed. For example, if there is no building material to be shipped because all shipments are completed, the display is not performed and the execution program ends.

  Next, FIG. 5 shows a configuration diagram of an example of variable initial values and execution program data creation stored in each IC tag. First, an execution program (execution PG) is created in a general programming language such as JAVA (registered trademark) in text format or C language. Next, the created execution program in a general programming language is converted by a compiler to create data for compressing the data amount of the execution program and improving execution efficiency. The converted execution program data is stored in a database. Then, the execution program data for storing the IC tag stored in the database is written to the IC tag using an RFID reader / writer or the like.

  FIG. 6 shows a configuration diagram of an example of creating data of an execution program stored in the PDA. The execution program stored in the PDA is created by calling the execution program stored in the IC tag by filling in the holes. First, an execution program is created in a general programming language such as JAVA (registered trademark) or C language in text format. Next, the created execution program in a general programming language is converted by a compiler to create data for compressing the data amount of the execution program and improving execution efficiency. The converted execution program is stored in a database together with a linkage editor that can be linked to the execution program written in the IC tag. Then, the PDA execution program data stored in the database is copied to the PDA and registered.

  FIG. 7 is a configuration diagram showing an example of the configuration of the execution program in the work support system of the present invention. In this configuration diagram, an interlocking image of the execution program stored in each IC tag and the execution program stored in the PDA is shown. An execution program for the A environment is written in the IC tag for the A environment. An execution program easy for the worker a to use is written in the IC tag for the worker a. When the worker a reads the IC tag for the A environment with the PDA, the PDA operating environment setting program and the work-specific program stored in the PDA are called and executed by the interpreter method. Next, when the worker a reads the IC tag for the worker a with the PDA, the unique setting program for each worker stored in the PDA is called and executed by the interpreter method.

  In the work support system of the present invention, the number of programs stored in a portable terminal such as a PDA (including portable terminals such as a mobile phone, a smartphone, and a tablet PC) is reduced as much as possible, and the reduced program is stored in an IC tag. Is a feature. By reading an IC tag in which a program is stored and executing the program according to the work purpose, the degree of freedom of the execution environment of a portable terminal such as a PDA increases.

  Furthermore, in the work support system of the present invention, each worker may define the variable initial value and the generation of the execution program for the program stored in the PDA. The result defined by the operator is written to the IC tag in the form of a variable initial value and an execution program. Next time, when the worker performs a PDA operation, the user can easily set the user-friendly setting by reading the IC tag to which the result defined by the worker is written. In this way, it is possible to respond flexibly to the convenience of field workers. It is also possible to not determine the operation procedure and function range at the time of system development.

  In addition, since the variable initial value and the execution program are stored in the IC tag, for example, a place where a wired LAN connection cannot be established with a server, such as a pre-shipment product place, a place where power cannot be pulled, and a wireless LAN connection. By utilizing the IC tag in places where it cannot be performed, it is possible to provide a mechanism for easily managing the location of products even in free locations.

  In the present embodiment, local location management is enabled by the PDA, but if necessary, after the PDA is moved to a location where it can be connected to the server, the information stored in the PDA is transmitted to and received from the server. Product location information can also be managed by a server. At that time, for example, an IC tag storing product information is attached to the product, the IC tag of the product is read by the PDA at the time of work such as shipping, and the product information is transmitted to the server after the work. Information management may be performed.

  As each IC tag, it is preferable to select an IC tag having a large memory capacity. For example, an 8000-byte IC tag having a large memory area size that is currently commercialized can be suitably used. Even when an IC tag with insufficient memory capacity is used, a huge memory space can be realized by utilizing a plurality of IC tags.

The flowchart of FIG. 8 shows another example of the basic processing flow of the work support system of the present invention. For example, a case where the worker a performs work related to the construction site A will be described. The same processes as those in FIG. 1 are denoted by the same reference numerals. As shown in the figure, the worker a turns on the power of the PDA having the IC tag reader (S1), and the IC tag for the A environment in which the operating environment data of the construction site A is stored by the IC tag reader (IC for operating environment) Tag) is read (S2). Next, the IC tag reader (IC tag for worker identification) is read by the IC tag reader (S3). By storing worker-specific data in the worker identification IC tag in advance, the worker simply reads the worker identification IC tag with the PDA and sets the PDA in an operating environment suitable for the worker. can do. Then, the PDA that has read the data in the steps S2 and S3 performs an initialization process for setting variable initial values with reference to the data (S4). After the initialization process, it is determined whether or not a location operation needs to be executed (S5-1). If it is determined that the execution is unnecessary (No), the process is completed. If it is determined that execution is necessary (Yes), a location operation is performed (S5). After the location operation, it is determined whether maintenance is necessary (S6). If it is determined that maintenance is not required (No), it is determined whether or not the next location operation needs to be executed (S5-1). When it is determined that the maintenance is necessary (Yes), the maintenance function A IC tag (maintenance function IC tag) is read (S7), and the maintenance function is executed in the PDA to perform the maintenance process (S8). After the maintenance process, it is determined whether or not the next location operation needs to be executed (S5-1).

  In the maintenance function IC tag, a variable initial value of the maintenance function and an execution program are written. If the maintenance function has options hierarchically, an IC tag is also prepared for each option.

  FIG. 9 is a diagram showing a storage image of the execution program stored in the IC tag. The execution program is written in the user usage area of the IC tag. The IC tag data for the A environment includes, for example, a variable initial value section, a layout screen display section, and a building material display processing section. In the variable initial value section, data such as a variable initial value a, a variable initial value b, and a variable initial value c corresponding to the variables a, b, and c are stored. In the layout screen display area, for example, execution programs (programs such as an if sentence and a Loop sentence) for determining the presence / absence of building material display information and the building material display processing unit are stored. In the building material display processing section, an execution program for data necessary for building material screen display is stored. The IC tag data for the worker a includes, for example, a system activation zone and a variable initial value zone. In the system startup area, for example, data such as a login ID and a password necessary for starting the system is stored. In the variable initial value section, operating environment data suitable for the worker a can be stored. For example, it is possible to set the highlight color to yellow in the PDA screen display. The IC tag data for the maintenance function A includes, for example, a variable initial value section. In the variable initial value section, data such as a variable initial value d, a variable initial value e, and a variable initial value f corresponding to the maintenance variables d, e, and f are stored.

  FIG. 10 is a configuration diagram illustrating an example of a configuration of an execution program in the work support system of the present embodiment. In this configuration diagram, an interlocking image of the execution program stored in each IC tag and the execution program stored in the PDA is shown. An execution program for the A environment is written in the IC tag for the A environment. An execution program easy for the worker a to use is written in the IC tag for the worker a. A maintenance execution program for the A environment is written in the maintenance IC tag for the A environment. When the operator reads the IC tag for the A environment with the PDA, the PDA operating environment setting program and the work-specific program stored in the PDA are called and executed by the interpreter method. When the worker reads the IC tag for the worker a with the PDA, the unique setting program for each worker stored in the PDA is called and executed by the interpreter method. When the worker reads the A environment maintenance IC tag with the PDA, the work-specific maintenance program stored in the PDA is called and executed by the interpreter method.

  According to the work support system of the present embodiment, it is not necessary to develop a maintenance screen as a system. In addition, additional development of maintenance functions is facilitated, and costs can be reduced. It also reduces program bugs. Note that normal maintenance is limited in function for managers and workers. In this embodiment, it is possible to eliminate the need to input a login ID or password to the system by reading the IC tag for the worker. The IC tag for the worker can set the environment according to the worker who uses it. FIG. 11A is an explanatory diagram when performing maintenance processing in the work support system of the present embodiment, and FIG. 11B is an explanatory diagram when performing maintenance processing in a system not according to the present invention. Show. In FIG. 11B, when a login ID and password are input and authenticated, a work menu screen is displayed. The maintenance screen is called from the work menu screen, and for example, the screen display color is set from the environment setting screen. On the other hand, according to the work support system of FIG. 11A, the work screen can be entered without inputting the login ID or password by reading the IC tag for the worker. Next, when the maintenance IC tag is read, the environment setting value stored in the maintenance IC tag is set, so that the environment setting on the maintenance screen can be made unnecessary. Therefore, according to the work support system of this embodiment, even an operator who is not used to PDA operation can easily set the environment.

(Embodiment 3)
In this embodiment, a plurality of types of IC tags having different radio wave bands are used as IC tags. UHF band IC tags and HF band IC tags are often used as a plurality of types of IC tags having different radio wave bands. When the PDA incorporates only an IC tag reader / writer corresponding to one of the used radio bands, an IC tag reader / writer compatible with the other used radio band can be externally attached via a USB connection or the like. FIG. 12 shows an example of a PDA 10 having such an IC tag reader / writer. In this example, the UHF band IC tag reader / writer 11 is built in the PDA 10 and the HF band IC tag reader / writer 12 is externally attached. FIG. 13 shows an example of the configuration of data stored in each IC tag when the PDA 10 is used. In this example, the UHF band IC tag is first read by the UHF band IC tag reader / writer 11, and then the HF band IC tag is read. The UHF band IC tag includes A information data and HF band switching program data. When the UHF band IC tag is read, an HF band switching program is started, and a screen indicating that reading from the HF band IC tag reader / writer 12 is possible is displayed on the PDA 10. Next, the HF band IC tag is read by the HF band IC tag reader / writer 12. The HF band IC tag includes B information data and UHF band switching program data. When the HF band IC tag is read, a UHF band switching program is started, and a screen indicating that reading from the UHF band IC tag reader / writer 11 is possible is displayed on the PDA. As described above, in the present embodiment, switching between the UHF band and the HF band in the screen operation can be made unnecessary, and the UHF band IC tag and the HF band IC tag can be easily performed with one PDA. Reading is possible.

(Embodiment 4)
The work support system of the present invention can be used as follows, for example, at a work site involving a large number of workers whose members are in a fluid state. As an example, when the worker x transports the building material X from the building material storage area, loads it, and ships it as follows. The worker x is given a PDA having an IC tag reader and a worker identification IC tag (for worker x) at the start of the work. The worker x IC tag stores data corresponding to the characteristics of the worker x and the work content. First, when the worker x reads his / her worker specifying IC tag with the PDA, the operating environment such as the color of the screen of the PDA and the size of characters to be displayed becomes optimum for the worker x. On the screen, items of “building material arrangement”, “moving”, and “shipping” are displayed as a list of work contents assigned to the worker x. In the display of each item, the display of the work place and the tag number of the IC tag for the operating environment are written together. In accordance with the display, the worker x goes to the first work place indicated in the item “Building material arrangement”. Then, the IC tag having the same number as the tag number written in the IC tag for the operating environment installed at the first work place is read by the PDA. Then, the details of the work contents that the worker x should perform at the first work place are displayed on the PDA screen. The layout diagram of the first work place is displayed on the screen, and the place of the building material X to be transported by the worker x is highlighted. According to the layout diagram, the worker x heads for the building material X. After confirming the building material X, when the IC tag attached to the building material X is read by the PDA, the work content for the building material X is displayed. Here, if an IC tag of a different building material is read, for example, “the building material is wrong. Please check and read the correct building material data” is displayed. When the work content for the building material X is displayed, the work is performed according to the display. When the building material X needs to be packaged or the like at the first work place, the work content is displayed. Information such as the storage location of the packing material and tools used for packing is also displayed. According to this display, the worker x packs the building material X. When the packaging is completed and the tool is returned, when the designated IC tag installed at the tool return place is read, the work at the first work place is completed and the work content list screen is displayed again. At this time, if the function of the IC tag writer is given to the PDA and the building material X packing completion information is written in the IC tag or the like at the tool return place, the process management can be performed by referring to this information later by the administrator. It becomes possible. Next, the worker x reads the IC tag having the same number as the tag number of the operating environment IC tag written together in the item “move” with the PDA. Then, on the PDA, the transportation method and the moving location of the building material X after packing are displayed. In the display, the tag number of the IC tag for the operating environment at the moving location is also written. When the building material X is transported to the designated moving location, an IC tag having the same number as the tag number written together is read from the operating environment IC tag installed at the location by the PDA. Then, how to place the building material X, the work contents, etc. are displayed. As with the work at the first work place, the work is performed in accordance with the instructions of the PDA, and when the series of work is completed, the worker x is the same as the tag number of the IC tag for the operating environment written in the item “shipping”. The numbered IC tag is read by the PDA. Then, the number of the truck to be loaded, the loading order, etc. are displayed on the PDA. If an IC tag for the operating environment is also attached to the truck, mistakes in loading can be prevented. In addition, information stored in the PDA of the worker x is written in the IC tag for operating environment given to the track, and the information is read and stored at the gate or the like at the time of shipment. The information stored in the PDA of the worker x includes information on the loaded building material X, packing status, moving status, work date, and the like. If an environment that can be connected to a server is prepared at the shipping gate, product location information can be managed by the server. In such a work site, the IT skill of the worker and the skill level of the work may vary. The work support system of the present invention can easily operate an IT device even for a worker unfamiliar with a PDA or the like. In addition, since the procedure of the work itself can be displayed in detail, it is not necessary to give a man-to-man instruction to a worker who newly enters the work site, and the work is efficiently performed. Moreover, it can be performed reliably. In addition, it is possible to check the progress of work and the location of the object from the input data.

  The present invention can be applied in various fields such as a factory site, a building site, and an agricultural site, and its uses are wide.
