  Hereinafter, embodiments will be described with reference to the drawings. First, an example of a process management system including a process management server according to an embodiment will be described with reference to FIG. The process management system 1 includes a customer terminal 2, a parts manufacturer terminal 3, a manufacturing management system 4, and a cloud 5. The customer terminal 2 and the parts manufacturer terminal 3 are connected to the cloud 5 via a communication line. A work area terminal 46, a department terminal 47, a process management server 48, and a device control terminal 49 in a company (manufacturer) that has received an order for a product from a customer are also connected to the cloud 5 via a communication line (for example, a LAN or WAN). Connected to.

  The process management system 1 is a product order from a customer, a product order, a part order to a parts maker, a part order, a part delivery, and a product (equipment) production using the delivered parts. A series of processes such as testing and product shipment as shown in FIG. 25 are managed. The configuration of the process management system 1 is not limited to the above, and may include other configurations.

  The customer terminal 2 is a terminal that is used for order management (product ordering, inquiry, etc.) by a customer who orders a product. In this example, there is one customer terminal 2, but when there are a plurality of customers, there may be a plurality of customer terminals 2. When a customer orders a product at the customer terminal 2, for example, an order / order management system (hereinafter also simply referred to as an order management system) is used. In addition to ordering products, the customer terminal 2 can be used to check the process from ordering to shipment of the ordered product, check the shipment schedule of the product and information on the product to be delivered (delivery information), etc. it can. Specifically, the above is realized by using the customer terminal 2 to access information (for example, a product information DB or a parts information DB, which will be described later) related to the ordered product stored in the database (DB) 51 on the cloud 5. To do.

  By ordering a product, information about the product is stored in the DB 51 of the cloud 5 as a product information DB.

  An example of the product information DB is shown in FIG. As shown in FIG. 2, the product information DB is based on a customer / system input including an order management number, an estimate number, a product name, a quantity, a desired delivery date, and a delivery location, an order status, a delivery date, an inventory status, and a communication item. It consists of the manufacturer / system input items. When ordering a product, an estimate number, a desired delivery date, and a delivery location are input via the customer terminal 2. The estimate number is, for example, a number assigned to estimate information (not shown) created in advance before ordering a product. When information such as an estimate number is input, the customer terminal 2 assigns (acquires) an order management number from a management device (management system) (not shown) that manages an order management number for managing orders for products. At the same time, the product name and quantity are acquired from the estimate information using the estimate number as a key, and the information is input to the product information DB. In this example, the product name is device 1 and the quantity is 100. When the above information is input, the customer terminal 2 accepts the order status. At this time, the delivery date is undecided. When the order management number is assigned, the order management number is notified to the department terminal 47 such as the business department of the manufacturer. This is to inform new orders. Further, items relating to the manufacturer / system input can be referred to by the customer by accessing the DB 51 through the customer terminal 2.

  The parts manufacturer terminal 3 is a terminal used for parts management by a parts manufacturer that ships parts necessary for manufacturing (assembling) the ordered product. In this example, there is one component manufacturer terminal 3, but when there are a plurality of component manufacturers, there may be a plurality of component manufacturer terminals 3.

  When a parts maker performs parts management, that is, order management of parts, shipping management, input of part information of parts to be shipped, etc., for example, an order management system is used. The component information here is, for example, information such as an EPC (Electronic Product Code) code, barcode data, component weight, and component appearance of a wireless IC tag attached to a component or a housing case that accommodates the component. Are input via the parts manufacturer terminal 3.

  The component information is stored in the DB 51 of the cloud 5 as a component information DB. The component manufacturer can access and refer to the product information DB and the component information DB stored in the DB 51 by using the component manufacturer terminal 3.

  An example of the component information DB is shown in FIG. As shown in FIG. 3, the part information DB is composed of items of an order management number, a part management number, wireless IC tag data, manufacturing status, part information, and an alarm. The order management number and the parts management number are associated (linked). The order management number assigned by the customer terminal 2 is input to the item of order management number, and the part management number is input to the item of part management number based on a parts list described later. In the wireless IC tag data item, information on a wireless IC tag attached to a component or a housing case that accommodates the component is input, but is blank until the dispensing of the component is completed. Here, paying out parts means that the parts are divided (secured) according to the usage within the manufacturer and put out on the production line. The item of manufacturing status indicates the manufacturing status of the product, and for example, a part arrival waiting is input.

  The part information further includes items of a part name, a necessary number, a payout number, a parts inventory, a part model number, a weight, an external view, a specification, a change history, and defect information. The component information is basically input based on a component list or the like that is input via the component manufacturer terminal 3. The part name is a name of the part, and is input based on a product configuration list described later. The required number is the number of parts necessary for manufacturing the product. The number of payouts is the number of parts paid out. The necessary number and the number of payouts are calculated with reference to the product information DB, the parts list, the product list described later, and the like. The parts inventory is the number of parts in stock. The part model number is an identification number for identifying the part type. The weight is the weight of one part or the entire housing case that houses the part. An external view is a figure which shows the external appearance of components or a storage case. The specification is a document that describes the specification of a part. The change history indicates a component change history (for example, the latest version). The defect information is information relating to a defect when a component has a defect. The alarm is an item that is input when it is necessary to call attention in the manufacturing process of the product. For example, when a part that is not an original part is coming to the work place, this is input.

  The parts inventory, external view, specification, change history, and defect information are input by referring to the part list diagram number using the part name as a key. The part model number and weight are extracted from a specification (not shown) and input.

  Here, an example of the product list is shown in FIG. 4, an example of the parts list is shown in FIG. 5A, and an example of the product configuration list is shown in FIG. 5B.

  As shown in FIG. 4, the product list includes items of product name, product inventory, and drawing number. Each product name is associated with a figure number consisting of an inventory quantity and an external view. For example, since the inventory number of the device 1 is 0, it is necessary to newly manufacture 100 ordered devices 1 (see FIG. 2). On the other hand, if the quantity of the ordered product (device) can be covered by the inventory quantity, it is not necessary to newly manufacture the product.

  As shown in FIG. 5A, the parts list includes items such as part name, part manufacturer name, arrival (scheduled) date, number of arrivals (estimated), part management number, wireless IC tag data, acceptance result, parts inventory, figure number. It is configured. The item of the wireless IC tag data is the wireless IC tag when the manufacturer completes the acceptance of the part delivered from the part manufacturer (for example, when the wireless IC tag attached to the part or the housing case of the part is read). The part management number written in the tag is input. The component management number of the wireless IC tag is numbered and written by a component manufacturer.

  In the item of the acceptance result, if the part management number assigned by the parts manufacturer and entered in the parts list matches the part management number obtained by reading the wireless IC tag, the fact that the acceptance was successful ( In this example, a circle) is input. The input of the acceptance result is performed via a terminal of a manufacturing department of the manufacturer. Note that, for the component whose component management number is A001-003, the items of the wireless IC tag data and the acceptance result are blank, and this indicates a state of waiting for the arrival of the component.

As shown in FIG. 5B, the product configuration list includes items of product name and part name.
The parts that make up a product are associated with each product.

  Here, an example of the data format of the above-described wireless IC tag is shown in FIG. As shown in FIG. 6, the wireless IC tag is composed of a rewritable prohibited area (unique area) and a rewritable area (user area). The rewrite prohibition area further includes a PC area, an AFI (Application Family Identifier) area, and a header value area. Based on the information described in the PC area, it can be determined which standard (ISO or EPC) the tag is used for. Further, based on the information described in the AFI area and the header value area, the application and user can be known. That is, it is possible to determine whether or not the wireless IC tag is in-house. The rewritable area is an area where a manufacturer or component manufacturer can write information for order management or manufacturing management. For example, a component management number assigned by the component manufacturer is written. When the information is written, the wireless IC tag is delivered to the manufacturer together with the parts.

  Returning to FIG. 1, the manufacturing management system 4 is a system in the manufacturer. When a product order is received from a customer, the production management system 4 performs necessary processes in a series of steps from product order to product shipment. The manufacturing management system 4 includes a wireless IC R / W (also referred to as a wireless IC tag reader / writer) 41 for reading a UHF band wireless IC tag, Bluetooth (registered trademark), which is disposed in a work area (for example, a factory that manufactures products) 40. ) GW 42 that receives a beacon signal, video camera 43 that shoots a worker or a part placed at a predetermined location (also simply referred to as a camera) 43, a scale for measuring the weight of a housing case in which a part or a part is housed 44, device control for transmitting information read by the scanner 45 for reading a barcode, the work area terminal 46 for receiving an inspection result input by an operator and an alarm notification to be described later, the wireless IC tag reader / writer 41 to the DB 51 of the cloud 5 Department terminals arranged in departments such as the terminal 49 and the sales department and business department outside the work area 40 7, and a process control server 48. The process management server 48 and the device control terminal 49 are arranged in a local manufacturer, but may be constructed on the cloud 5 as shown in FIG.

  As shown in FIG. 26, the wireless IC tag reader / writer 41 works at a part placed at a predetermined place (for example, a scale 44) or a wireless IC tag attached to a housing case for housing the part, or at a work place. A wireless IC tag (worker medium) attached to a worker's work clothes or hat is read through a wireless IC tag antenna. By attaching and reading a wireless IC tag in which identification information (worker identification information) for identifying the worker is written to the worker, it is possible to manage when, where, and who worked. Further, when a manufacturing defect occurs after the product is shipped, it is possible to specify whether the part of the lot itself has a cause or the cause of the worker's work. An example of the location of the wireless IC tag antenna, the work table, and the reading range of the wireless IC tag is as shown in FIG.

  In addition, since the predetermined place where the storage case for storing the part and the part is placed is a scale 44 that can measure the weight, the weight to be measured and the weight of the part or the storage case to be originally measured can be obtained. Can be compared. As a result, it is possible to detect the placement of unintended parts or items unrelated to the product, and to prevent the manufacture of a product incorporating the wrong part, thereby improving the quality of the product. .

  In addition, the camera 43 can be installed at the work place to capture images of parts and workers, and the image of the appearance of the imaged part is compared with the image of the external appearance of the part that should be captured in advance. can do. Thereby, when the appearances of the parts are different, it is possible to detect that an unplanned part has been placed, and to improve the quality of the manufactured product.

  Data acquired by the wireless IC tag reader / writer 41, GW 42, camera 43, scale 44, etc. is transmitted to the device control terminal 49. The device control terminal 49 receives the received information, for example, the time when the wireless IC tag reader / writer 41 reads the wireless IC tag (wireless IC tag attached to a part or an operator), the identification information of the read wireless IC tag reader / writer 41, the wireless An ID (for example, a part management number or identification information assigned to an operator) written in the IC tag is stored in the DB 51 as a reception information table (not shown), for example.

  The work area terminal 46 is, for example, a PC or a tablet, and accepts input such as test check results, and the input check results are stored in the DB 51 via, for example, a communication line. The department terminal 47 is, for example, a PC or a tablet, and accesses the DB 51 in response to a request from a user of each department, and displays the status (situation) of product manufacture, information on product manufacturing operations, information on products, and the like. Output to the display. Further, the department terminal 47 and the work area terminal 46 receive an alarm notification described later, and output the contents of the alarm based on the received alarm notification.

  Here, an example of the configuration of the process management server according to the embodiment will be described with reference to FIG. The process management server 48 includes an acquisition unit 281, a determination unit 282, and a notification unit 283. The configuration of the process management server 48 is not limited to this, and may include other configurations.

  The acquisition unit 281 acquires information stored in the DB 51, and acquires information from, for example, the reception information table.

  The determination unit 282 includes information acquired from the reception information table of the DB 51 by the acquisition unit 281 (information received from the wireless IC tag reader / writer 41 when the wireless IC tag is read) and a wireless IC tag (component management number). The wireless IC tag (component management number) acquired based on the correspondence table in which the identification information of the wireless IC tag reader / writer 41 to which the wireless IC tag (component management number) is to be read is associated. It is determined whether or not the wireless IC tag (component management number) is read by the IC tag reader / writer. That is, it is determined whether a scheduled part is placed in the work place. The correspondence table may be a manufacturing shift described later, or may be a table provided separately.

  If the determination unit 282 determines that the wireless IC tag reader / writer 41 to be read has not read, the determination unit 282 inputs abnormal component detection to the alarm item in the component information DB, assuming that the part to be originally placed is not in the work place.

  The notification unit 283 acquires notification setting information to be described later when there is an input such as abnormal component detection in the alarm item of the component information DB, and based on the acquired notification setting information, the work area terminal 46 and related department terminals An alarm notification is sent to 47. Note that the alarm notification may be performed not only on the terminal but also on a patrol lamp or the like as will be described later. Since the work place often has a loud work sound and the worker does not always look at the terminal screen, the alarm notification by the patrol lamp is effective.

  In addition, the process management server 48 monitors the status of product orders, part order / arrival, product assembly / test / shipment, and the like. The process management server 48 also monitors work information such as workers, parts used, and required time. Thereby, time schedule management can be performed and a change of a work process etc. can be performed. Further, the process management server 48 monitors product information such as part lot, serial number, PT (print) plate number, and software version number. Further, the process management server 48 creates a work process based on the received process instruction and the like, and generates a later-described manufacturing shift, manufacturing personnel information, process information, and the like stored in the DB 51.

  Here, an example of notification setting information is shown in FIG. The notification setting information indicates which section uses which means to notify the alarm when there is information input in the alarm item of the component information DB. The notification setting information includes items such as an order management number, abnormal component detection, worker difference notification, component defect occurrence, and mail information.

  In the case of abnormal part detection, that is, if there is no part that should be placed in the work place by reading the wireless IC tag attached to the part or the housing case that contains the part or checking the weight of the part, e-mail The alarm notification is made using a display of the corresponding work place, a patrol lamp installed in the work area 40, and the like. In this example, alarm notification by e-mail is made to the manufacturing department (manufacturing ML) and the guarantee department (guarantee ML) based on the mail information.

  Also, in the case of worker difference detection, that is, when there is no worker who originally works at the work place by reading the wireless IC tag attached to the worker's work clothes or hat, e-mail, display, patrol lamp Use to notify. In this example, alarm notification by e-mail is made to the manufacturing department (manufacturing ML) and the guarantee department (guarantee ML) based on the mail information.

  In addition, when a component defect occurs, that is, when a component defect is found during work or the like, notification is made using an e-mail or a display. In this example, the alarm notification by e-mail is made to the manufacturing department (manufacturing ML), the guarantee department (guarantee ML), the business department (business ML), and the development department (in charge technology) based on the mail information. Is called.

  The mail information may include a mail address used when sending an electronic mail to each department.

  An example of the manufacturing shift is shown in FIG. The manufacturing shift indicates a manufacturing shift at the work place (in this example, line 1-1). The work place item may include identification information for identifying the wireless IC tag reader / writer 41 installed for each work place. Thereby, the component management number can be associated with the wireless IC tag reader / writer 41 from which the component management number is to be read.

  In the manufacturing shift shown in FIG. 8, from 9 o'clock to 12 o'clock, the person in charge A uses the parts of the three parts management numbers (A0001-003, D0001-001, J0001-002), and from 13:00 to 17:00 Up to this, it is shown that the person in charge B uses the parts having the same part management number for manufacturing. The time zone from 0 o'clock to 9 o'clock and 17 o'clock to 0 o'clock is not manufactured, and the time zone from 12 o'clock to 13 o'clock is a lunch break.

  Note that, for example, worker identification information allocated to the worker may be input to the item of the worker name. Accordingly, the worker identification information can be associated with the wireless IC tag reader / writer 41 from which the worker identification information is to be read. The manufacturing shift includes information in which a component image (image ID) corresponding to the component management number is associated with identification information (ID) of the camera (imaging device) 43 from which the component image is to be captured. It may be. Note that the image of the component corresponding to the image ID is stored in a storage area (not shown) of the DB 51, for example. In addition, the manufacturing shift may include information on the weight to be measured of the part placed on the balance 44 of the work place or the housing case for housing the part corresponding to the work place. For example, between 9 o'clock and 12 o'clock, since three parts are used, information on the weight of each part is included.

  An example of manufacturing personnel information is shown in FIG. The manufacturing personnel information indicates the manufacturing skill of the worker who performs the manufacturing for each apparatus. The manufacturing personnel information shown in FIG. 9 includes personnel information and manufacturing skills. The personnel information includes the name of the worker and the ID of the wireless IC tag data assigned to the worker. The manufacturing skill indicates the manufacturing skill (skill level) of the worker for each apparatus. For example, the person in charge A has the manufacturing skills from the apparatus 1 to the apparatus 4, while the person in charge B has only the manufacturing skills of the apparatus 1 and the apparatus 2. In FIG. 9, manufacturing skills are divided into circles (with skills) and blank spaces (without skills), but the present invention is not limited to this. For example, the skills may be shown numerically.

An example of the process information is shown in FIG. Process information shows the manufacturing process for every apparatus. For example, the apparatus 1 is manufactured through each process of process 1 (line 1-1), process 2 (line 1-2), process 3 (line 2-1), and process 4 (line 2-2). Is shown.
The cloud 5 collectively manages the various types of information described above using the DB 51.

  Next, an example of various processes using the customer terminal 2 will be described with reference to FIG. As shown in FIG. 12, the customer terminal 2 activates the order management system, accepts a selection from a predetermined menu, and checks the selected menu (event check) (step S1201). The customer terminal 2 determines whether an order input menu for a new product has been selected (step S1202). If the order is for a new product (Yes in step S1202), an order reception process is performed (step S1203). The order reception process will be described later.

  If it is not an order for a new product (No in step S1202), the customer terminal 2 determines whether an order status inquiry menu for inquiring the latest delivery schedule and status is selected (step S1204). If it is an order status inquiry (Yes in step S1204), an order status notification process is performed (step S1205). The order status notification process will be described later.

  If it is not an order status inquiry (No in step S1204), the customer terminal 2 determines whether a delivery completion menu input by the customer after receipt of the product has been selected (step S1206). When the delivery completion is selected (Yes in step S1206), a delivery completion notification process is performed (step S1207). The delivery completion notification process will be described later.

  If the delivery completion is not selected (No in step S1206), the customer terminal 2 determines whether the inquiry menu for product information or parts information including products shipped in the past has been selected (step S1208). If an inquiry such as product information is selected (Yes in step S1208), an information matching process is performed (step S1209). The information matching process will be described later.

  When it is not selection of inquiry, such as product information (No in Step S1208), customer terminal 2 performs error notification (Step S1210).

  The order reception processing subroutine will be described with reference to FIG. An estimate number, desired delivery date, delivery location, etc. are input via the customer terminal 2 (step S1301). When input, the management server (not shown) that manages the order management number assigned at the time of ordering the product issues an order management number (step S1302), and the customer terminal 2 writes the issued order management number in the product information DB. (Step S1303). The customer terminal 2 acquires estimate information (not shown), and inputs the product name and quantity to the product information DB based on the acquired estimate information (step S1304). The customer terminal 2 notifies the order management number to the process management server 48 (step S1305), and sets the order status in the product information DB to reception (step S1306).

  The subroutine of the order status notification process will be described with reference to FIG. The customer terminal 2 determines whether there is an order management number, that is, it has been issued (step S1401). If there is an order management number (Yes in step S1401), the customer terminal 2 acquires a desired order status from the DB 51, The acquired order status is notified (step S1402). The notification of the order status here is to display the order status on a display, for example. If there is no order management number (No in step S1401), the order status notification process ends.

  The subroutine for the delivery completion notification process will be described with reference to FIG. The customer terminal 2 determines whether there is an order management number (step S1501). If there is an order management number (Yes in step S1501), the customer terminal 2 sets the order status in the product information DB to delivered (step S1502). . As a result, a delivery completion notice is sent to each department of the manufacturer, parts manufacturer, and the like (step S1503). Thereby, it can be confirmed that the delivery of the product has been successfully completed. If there is no order management number (No in step S1501), the delivery completion notification process ends.

  The information inquiry processing subroutine will be described with reference to FIG. The customer terminal 2 determines whether there is an order management number (step S1601). If there is an order management number (Yes in step S1601), the product information DB inquiry (step S1602) and the parts information DB inquiry ( Step S1603) is performed to notify the inquired information (step S1604). The notification of information here is to display the inquired information on a display, for example. If there is no order management number (No in step S1601), the information inquiry process ends.

  The order status inquiry and the information inquiry can be performed not only at the customer terminal 2 but also at the parts manufacturer terminal 3 or each terminal of the manufacturer according to the request of the parts manufacturer or the manufacturer.

  Next, an example of the manufacturing process management process in the manufacturer will be described with reference to FIG. The process management server 48 checks the alarm item in the component information DB (step S1701), and determines whether there is an input to the alarm (step S1702). If there is an alarm (Yes in step S1702), an alarm notification process is performed (step S1703). The alarm notification process will be described later.

  If there is no alarm (No in step S1702), an event check is performed (step S1704), and it is determined whether there is an order management number notification from another system (customer terminal 2), that is, whether there is an order for a new product (step S1704). S1705), if it is an order for a new product (Yes in step S1705), a manufacturing process adjustment process is performed (step S1706). The manufacturing process adjustment process will be described later.

  If it is not an order for a new product (No in step S1705), it is determined whether it is a change due to a delay in parts delivery by the terminal of the manufacturing department, a worker change, a part defect, or the like, that is, a process correction (step S1707). In the case (Yes in step S1707), the manufacturing process adjustment process is performed.

  If it is not a process correction (No in step S1707), it is determined whether a manufacturing status inquiry has been received from each department (step S1708). If the manufacturing status is inquired (Yes in step S1708), a manufacturing status notification process is performed (step S1708). S1709). The manufacturing status notification process will be described later.

  If it is not an inquiry about the manufacturing status (No in step S1708), it is determined whether it is the reception of the wireless IC tag data, that is, whether the manufacturing status is input (step S1710), and if the manufacturing status is input (Yes in step S1710). Then, the manufacturing status input process is performed (step S1711). The manufacturing status input process will be described later. As an input of the manufacturing status, for example, there is an input for notifying the reception of the data of the wireless IC tag, the result of the test by the operator, and the part defect found at the time of manufacturing. If the manufacturing status is not input (No in step S1710), the manufacturing process management process ends.

  The alarm notification processing subroutine will be described with reference to FIG. If there is an input in the alarm item of the parts information DB, the process management server 48 acquires notification setting information (step S1801), and based on the acquired notification setting information and the content input in the alarm item, an alarm is generated. Notification is performed (step S1802).

  The manufacturing process adjustment processing subroutine will be described with reference to FIG. For example, the process management server 48 acquires the notified order management number (step S1901), and determines whether there is a parts information DB (step S1902). If there is no component information DB (No in step S1902), a component information DB is created (step S1903). If there is a parts information DB (Yes in step S1902), the process management server 48 determines whether parts have been secured (step S1904). If no parts have been secured (No in step S1904), parts procurement Processing is performed (step S1905). The parts procurement process will be described later. If the parts have been secured (Yes in step S1904), the process management server 48 determines whether the process has been adjusted (step S1906). If the process has not been adjusted, the process is adjusted, that is, the product is shipped from manufacture. The standard work process up to this point is created (step S1907). If the process has been adjusted (Yes in step S1906), the manufacturing process adjustment process is terminated.

  The subroutine for the parts procurement process will be described with reference to FIG. For example, the business department terminal determines whether to wait for parts to be dispensed (step S2001). When waiting for parts to be dispensed (Yes in step S2001), the parts procurement process ends. On the other hand, if the part is not waiting to be dispensed (No in step S2001), the business department terminal determines whether the part has been received (step S2002). If the part has not been received (No in step S2002), a part purchase request is issued. This is performed (step S2003). Thereafter, when a parts purchase request is made to the parts maker, the manufacturing status is set to the waiting for parts arrival (step S2004).

  On the other hand, if the parts have already been received (Yes in step S2002), the parts management number is written in the wireless IC tag data of the parts list (step S2005), and the parts are dispensed to pay out the parts necessary for manufacturing when the parts are ready. According to the instruction (step S2006), the manufacturing status is set to a part payout waiting state (step S2007). When the payout is completed after the parts payout instruction, the parts management number is written in the wireless IC tag data item of the parts information DB.

  The manufacturing status notification process subroutine will be described with reference to FIG. The terminal that has received the inquiry about the manufacturing status determines whether or not there is an order management number (step S2101). If there is an order management number (Yes in step S2101), the terminal acquires the desired manufacturing status from the DB 51 and acquires it. The manufactured status is notified (step S2102). The notification here is, for example, displaying on a display of a terminal. If there is no order management number (No in step S2101), the manufacturing status notification process ends.

  The manufacturing status input process subroutine will be described with reference to FIG. The process management server 48 determines whether a wireless IC tag is detected by the wireless IC tag reader / writer 41 in the work area 40 (step S2201). If a wireless IC tag is detected (Yes in step S2201), wireless IC tag data processing is performed (step S2202). The wireless IC tag data processing will be described later.

  If no wireless IC tag is detected (No in step S2201), a weight check process for checking the weight measured by the scale 44 is performed (step S2203). In this example, the weight check process is performed, but this process may be omitted. The weight check process will be described later.

  It is determined whether or not the input is made by the manufacturing worker who manufactures the product through the work area terminal 46 (step S2204), and is input by the manufacturing worker (for example, input of information on the number of the manufactured PT (printed) board). In the case (Yes in step S2204), manufacturing data processing such as associating information on the machine number of the PT plate with the product information DB or the like is performed (step S2205).

  On the other hand, if the input is not made by the manufacturing worker (No in step S2204), it is determined whether the input is made via the work area terminal 46 by the test worker who inspects the manufactured product (step S2206). When the input is a test operator (for example, input of the test result of the manufactured PT plate) (Yes in step S2206), test data processing such as associating the test result with the product information DB or the like is performed (step S2207).

  On the other hand, if it is not an input by the test operator (No in step S2206), it is determined whether the input is made by a component manufacturer for notifying a part lot defect, for example (step S2208). If the input is made by a component manufacturer (Yes in step S2208), component data processing for avoiding the use of a defective component is performed (step S2209).

  On the other hand, if the input is not made by the component manufacturer (No in step S2208), it is determined whether the input is other than the above (step S2210). If the input is other (Yes in step S2210), the corresponding input process is performed. If it is not other input (No in step S2210), the manufacturing status input process ends.

  A subroutine of the wireless IC tag data processing will be described with reference to FIG. It is determined whether the detected wireless IC tag is a company tag (for example, a tag of a component manufacturer) (step S2301). If the tag is not a company tag (No in step S2301), the manufacturer illegal tag detection indicating that the tag is not a company tag is input to the alarm item of the parts information DB (step S2302).

  On the other hand, if it is a company tag (Yes in step S2301), it is determined whether it is an operator's wireless IC tag (step S2303). If it is not an operator's wireless IC tag (No in step S2303), a component (or component It is determined whether the wireless IC tag is attached to the housing case (step S2304). If it is not a wireless IC tag attached to a component (No in step S2304), it is determined whether it is a wireless IC tag of a product in which components are combined (step S2305). If it is not a product wireless IC tag (No in step S2305), an unauthorized use tag detection is input on the assumption that a wireless IC tag whose use is unknown is detected in the alarm item of the component information DB (step S2306).

  On the other hand, if the wireless IC tag belongs to the worker (Yes in step S2303), is attached to a part (Yes in step S2304), or is a product (Yes in step S2305). The manufacturing shift is checked (step S2307), and it is determined whether there is a problem in the check result (step S2308). Specifically, it is checked whether the detected wireless IC tag is originally for a worker who works at the work place, or is a part originally planned for the work place. Further, when the wireless IC tag is attached to a component or a housing case that houses the component, the weight of the measured component or the housing case should be originally measured at the work place based on the manufacturing shift. It may be checked whether it is the weight, or whether the image of the imaged part is an image of the part imaged by the imaging device that should be imaged at the work place.

  If there is a problem with the check result, for example, it is not a wireless IC tag of a part originally scheduled at the work place (No in step S2308), an alarm part detection indicating that the part is not a scheduled part is included in the alarm item of the part information DB. Input (step S2309).

  On the other hand, if there is no problem in the check result (Yes in step S2308), it is determined whether the work can be started, for example, whether the original worker or parts are ready (step S2310). If the work can be started (Yes in step S2310), the process number of the manufacturing shift is acquired (step S2311), and the manufacturing status of the component information DB is set to wait for the start of the acquired process number (step S2312). A work start wait is input in the alarm item (step S2313). On the other hand, if the work cannot be started (No in step S2310), the wireless IC tag data processing ends.

  If the wireless IC tag is not detected even when the work start time approaches, that is, if the worker does not come to the work place or the part is not in the work place, the wireless IC tag is detected as an alarm item in the parts information DB. It may be input that the information is not displayed.

  Moreover, when the original worker and parts are not prepared, the work process may be readjusted and changed.

  In addition, after the start of manufacturing, even if the work is in progress, there will be fluctuations in the reading of the wireless IC tag, for example, when the worker leaves or changes the position, or when parts are moved, changed, or added. When the work does not end even after the scheduled work end time has passed, for example, when the worker does not leave or the part is left on, the fact may be entered in the alarm item of the parts information DB.

  The subroutine of the weight check process will be described with reference to FIG. It is determined whether the weight measured by the work place scale 44 is 0 (step S2401). If the weight is not 0 (No in step S2401), the weight abnormality detection is input in the alarm item of the parts information DB. (Step S2402). On the other hand, if the weight is 0 (Yes in step S2401), the weight check process ends with no abnormality. Since this subroutine is processing when the wireless IC tag is not detected, the weight is usually zero. The fact that the weight is not 0 means that a part not attached with the wireless IC tag is placed, an object not related to the production line is placed, and the like.
