The in-vehicle terminal 10 and the information management center 20, or the invoice embedded RFID 30 and the information management center 20, or the ordering management terminal 40 and the information management center 20, or the supplier management terminal 60 and the information management center 20, or the in-vehicle terminal 10 The process performed between the in-container RFID receiving antenna 50 or the delivery form embedded RFID 30 and the ordering management terminal 40 is shown.

  When the user inputs the power of the in-vehicle terminal 10, the information management center receives a power ON signal from the in-vehicle terminal 10 (S200), and transmits initial screen information to the in-vehicle terminal (S205). The in-vehicle terminal receives the initial screen information from the information management center (S105) and displays the initial screen (S110). An initial screen is shown in FIG.

  When the user inputs vehicle information (transport company code, vehicle number, transporter code) and supplier information (supplier code) on the initial screen and touches the “loading start” button (S115), the vehicle and The destination information (transport company code, vehicle number, transporter code, supplier code) is transmitted to the information management center 20 (S120). Specific examples of the screen input by the user at this time are shown in FIGS. 4-1 to 4-2, and specific examples of the vehicle and supplier information to be transmitted are shown in FIGS. However, if the user inputs vehicle and ordering source information and touches the “arrival” button in S115, vehicle information (transportation company code, vehicle number, transporter code) and ordering source information (ordering source code) are managed as information. It is transmitted to the center 20 (S120). A specific example of the screen input by the user at this time is shown in FIG. 4-2, and a specific example of the transmitted vehicle and ordering source information is shown in FIG.

  These pieces of information are received by the processing device 90 of the information management center via the network (S210).

  Hereinafter, with respect to the processing S215 to S225, the vehicle and supplier information or vehicle and ordering source information data shown as specific examples in FIGS. 5-1 to 5-2, and the information management DB 80 shown as a specific example in FIG. This will be described using data. FIG. 6A shows loading instruction information 801, FIG. 6-2-1 shows procurement component information 802 before loading start status update processing in S220, and FIG. 6-2-2 shows status update at loading start in S220. FIG. 6-3-1 shows the procurement part information 802 before the arrival status update process in S220, and FIG. 6-3-2 shows the procurement part after the arrival status update process in S220. The component information 802 is shown.

  When the vehicle and supplier information is received in S210, the processing device 90 of the information management center receives the vehicle and supplier information (transport company code: BBB, vehicle number: 555-0101, transporter code) received in S210. : Y-001, supplier code: A01) and “loading instruction date: 20060930”, the loading instruction information is retrieved from the loading instruction information 801 of the information management DB 80 (S215). The load instruction data to be searched for in S215 is three records of load instruction numbers: S000000123, S000000124, and S000000125. The processing device 90 of the information management center searches the procurement part information 802 using the order numbers of these three records: H00001, H00002, and H00003 as a key, and updates the part status of the three records to “loading” (S220). At this time, update processing is performed only when the component status of the record to be updated in the procurement component information 802 is space, and update processing is not performed when the status is other than space. The processing device 90 of the information management center is configured to update the status of the order numbers H00001, H00002, and H00003, and the loading instruction information (loading instruction date, transport company code, vehicle number) of the loading instruction numbers S000000123, S000000124, and S000000125. The transporter code, the loading instruction number, the part number, the number of instructions, the supplier, the ordering source) are transmitted to the in-vehicle terminal 10 (S225).

When the vehicle and the orderer information are received in S210, the information management center processing device 90 receives the vehicle and the orderer information received in S210 (transportation company code: BBB, vehicle number: 555-0101, transporter code: Y -001, ordering source code: C01) and “loading instruction date: 20006930” as keys, the loading instruction information is retrieved from the loading instruction information 801 of the information management DB 80 (S215). The load instruction data to be searched for in S215 is one record with the load instruction number: S000000123. The processing device 90 of the information management center searches the procurement part information 802 using the order number: H00001 of this record as a key, and updates the part status to “arrival” (S220). At this time, update processing is performed only when the component status of the record to be updated in the procurement component information 802 is “transporting”, and update processing is not performed when the status is other than “transporting”. The processing device 90 of the information management center includes the “status” after the status update of the order number: H00001 and the loading instruction information of the loading instruction number: S000000123 (loading instruction date, transportation company code, vehicle number, transporter code, loading instruction number) , The part number, the number of instructions, the supplier, the orderer) are transmitted to the in-vehicle terminal 10 (S225).
The in-vehicle terminal 10 receives the information transmitted from the information management center in S225 via the network (S125). The in-vehicle terminal 10 displays the received loading instruction information and procurement component information on the screen (S130). As a specific example of the screen displayed in S130, a specific example of the screen received from the information management center by the user touching the “loading start” button in S115 is shown in FIG. A specific example of the screen received from the center is shown in Figure 7-2.

  When the user touches the “loading completion” button on the “load receiving instruction result” screen of FIG. 7-1 of the in-vehicle terminal 10 (S135), a reading activation signal is transmitted to the receiving antenna 50 (S140).

  When the receiving antenna 50 receives this reading start signal (S500), all RFIDs 70 attached to the loaded items in the transport vehicle container are read in a batch (S505), and the read RFID information (part number, packing number, number of pieces) ) Is transmitted to the in-vehicle terminal 10 (S510).

  The RFID information (part number, packing number, number) is received by the in-vehicle terminal 10 via the network (S145), and the loading instruction information received by the in-vehicle terminal 10 in S125 ("loading instruction date: 20060930"). “Transport company code: BBB”, “Vehicle number: 555-0101”, “Transporter code: Y-001”) and the information are transmitted to the information management center (S150).

  These pieces of information are received by the processing device 90 of the information management center via the network (S230). The processing device 90 uses the received loading instruction information (“loading instruction date: 20060930”, “transport company code: BBB”, “vehicle number: 555-0101”, “transporter code: Y-001”) as a key, and the loading instruction information 801. The loading instruction information (loading instruction number: part number of S000000123 to S000000125, number of instructions) for the loaded and unreceived parts is acquired from the ID and duplicated from the received RFID information (part number, packing number, number) The data is excluded and matched with the data obtained by counting the number of each part number (S235), and when there is an unmatch, the procurement part information only for the instruction data that is displayed in S130 and that is not unmatched The part status of 802 is updated to “in transit” (S240). If unmatching does not occur, the component status of the procurement component information 802 is updated to “in transit” for all relevant instruction data displayed in S130 (S245).

  At this time, update processing is performed only when the component status of the record to be updated in the procurement component information 802 is “loading”, and update processing is not performed when the status is other than “loading”.

  For example, when the RFID information (part number, packing number, number) attached to the load is the result shown in FIG. 8-1-1, the processing device 90 eliminates duplicate reading data and totals the number for each part number. The result is as shown in Fig. 8-1-2. The part number: 777-777 has a track record of 190, the part number: 777-777, the loading instruction number: S000000124, the number of instructions 200, and the unloading instruction number: S000000123, S000000125 Update the part status of 802 to 2 records “in transit”. FIG. 6-2-3 shows procurement component information 802 as a result of updating the procurement component information 802 before update shown in FIG. 6-2-2.

  For example, when the RFID information (part number, packing number, number) attached to the load is the result shown in FIG. 8-2-1, the processing device 90 eliminates duplicate reading data and totals the number for each part number. The result is as shown in Fig. 8-2-2. Since the actual number and the instruction number all match, the part status of the procurement part information 802 is updated to 3 records “in transit” for the loading instruction numbers: S000000123 to S000000125, assuming that an unmatch has not occurred. FIG. 6-2-4 shows procurement part information 802 as a result of updating the pre-update procurement part information 802 shown in FIG. 6-2-2.

  In both cases where an unmatch occurs or does not occur, the matching result information (loading instruction number, part number, status, loading number, loading date) for the loading instruction numbers S000000123 to S000000125 displayed in S130 ) Is transmitted to the in-vehicle terminal 10 (S250).

  These pieces of information are received by the in-vehicle terminal 10 via the network (S155) and displayed on the loading / receiving instruction result screen (S160 or S165). If there is an actual unmatch in the matching result, that is, in the example of FIG. 6-2-3, the column of the stacking instruction number: S000000124 is flashed, and if there is a surplus stacking product that does not have the corresponding instruction, the part number and number Is displayed (S160). When there is no unmatch in the matching result, that is, in the example of FIG. 6-2-4, all the columns of the stacking instruction numbers: S000000123 to S000000125 are displayed in green (S165). A specific screen example of S160 is shown in FIG. 9-1, and a specific screen example of S165 is shown in FIG. 9-2.

  However, if the user touches the “Receiving” button on the screen of FIG. 7-2 (S135), the instruction and the result are matched in S235 as described above, and if an unmatch occurs, S130 The component status of the procurement component information 802 is updated to “receiving” only for the corresponding instruction data displayed in step S3 and not the unmatched instruction data (S240). If unmatching does not occur, the component status of the procurement component information 802 is updated to “receiving” for all relevant instruction data displayed in S130 (S245). At this time, update processing is performed only when the component status of the record to be updated in the procurement component information 802 is “arrival”, and update processing is not performed when the status is other than “arrival”.

  For example, when the RFID information (part number, packing number, number) attached to the loaded product is the result shown in FIG. 8-3-1, the processing device 90 eliminates duplicate read data and totals the number for each part number. The result is shown in Fig. 8-3-2. Since the actual number of part numbers 888-888 is 80 and the number of instructions of loading instruction number S888123 of part number 888-888 is 100 and unmatched, the part status of the procurement part information 802 is not updated. FIG. 6-3-3 shows procurement component information 802 obtained by updating the procurement component information 802 before update shown in FIG. 6-3-2 in S240.

  For example, when the RFID information (part number, packing number, number) attached to the load is the result shown in FIG. 8-2-1, the processing device 90 eliminates duplicate reading data and totals the number for each part number. The result is as shown in FIG. 8-2-2. Since the actual number and the number of instructions all match, it is assumed that no unmatch has occurred, and the part status of the procurement part information 802 is set to “Unloading” for the loading instruction number: S000000123. Update to FIG. 6-3-4 shows procurement part information 802 obtained by updating the procurement part information 802 before update shown in FIG. 6-3-2 in S240.

  In both cases of unmatching and non-matching, the matching result information (loading instruction number, part number, status, loading number, loading date) is displayed for the loading instruction number: S000000123 displayed in S130. It transmits to the vehicle-mounted terminal 10 (S250).

  These pieces of information are received by the in-vehicle terminal 10 via the network (S155) and displayed on the loading / receiving instruction result screen (S160 or S165). When there is an actual unmatch in the matching result, that is, in the example of FIG. 6-3-3, the column of the stacking instruction number: S000000123 is displayed blinking, and if there is a surplus stacked product for which there is no corresponding instruction, the part number and the number Is displayed (S160). When there is no unmatch in the matching result, that is, in the example of FIG. 6-3-4, the column of the stacking instruction number: S000000123 is displayed in yellow (S165). FIG. 9-3 shows a specific example of the screen displayed in S160 after the user touches the “Receiving” button on the screen of FIG. 7-2, and FIG. 9-4 shows a specific example of the screen displayed in S165.

  Upon completion of processing in S245, vehicle information, loading instruction / actual information, and part status information (order number, part number, quantity, delivery date, ordering party, supplier, transportation company code, vehicle number, transporter code, loading instruction number) , Status) is transmitted to the RFID 30 embedded in the delivery note (S255).

  The information is received by the delivery form embedded RFID 30 via the network (S300), and the received information is written in the RFID (S305). FIG. 10-2 shows a specific example of information 301 to be written in the RFID in S305 after the user touches the “loading completion” button on the “load receiving instruction result” screen of FIG. FIG. 10-3 shows a specific example of the information 301 to be written in the RFID in S305 after the user touches the “load receipt” button on the “load receipt instruction result” screen of FIG. Moreover, the data of RFID30 before S305 update processing are shown in FIG.

  When the user reads the invoice embedded in the RFID 30 with the order management terminal 40 (S400), the read RFID information (order number, part number, quantity, delivery date, order source, supplier, transport company code, vehicle number, transporter) Code, loading instruction number, and status) are transmitted to the information management center (S405).

  These pieces of information are received by the processing device 90 via the network (S260), the procurement part information 802 is searched using the order number of the received RFID information as a key (S265), and the searched order information (order number, part number, The number of orders, delivery date, supplier, transport company code, vehicle number, transporter code, loading instruction number, and status) are transmitted to the order source management terminal 40 (S270).

  These pieces of information are received by the orderer management terminal 40 via the network (S410) and displayed on the screen (S415). A specific example of the acceptance screen of S415 is shown in FIG.

  When the user presses the “accept” button on the acceptance screen (FIG. 11-1) of the orderer management terminal 40 (S420), the component information (order number, part number, order quantity, delivery date, purchase) displayed on the screen is displayed. The destination, transport company code, vehicle number, transporter code, loading instruction number, and status) are transmitted to the information management center (S425).

  Hereinafter, the process of S275-S285 is demonstrated using the specific example shown to FIGS. Information sent in S245 (order number: H00001, part number: 888-888, order quantity: 100, delivery date: 20061001, supplier: A01, shipping company code: BBB, vehicle number: 555-0101, transporter code: Y-001, loading instruction number: S000000123, status: receiving) is received by the processing device 90 via the network (S275), the procurement part information 802 is searched using the order number: H00001 as a key, and the part status is set to “ Update to “Accepted” (S280). At this time, the update process is performed only when the part status of the procured part information 802 retrieved and extracted is “receiving”, and the update process is not performed when the status is other than “receiving”. FIG. 6-3-5 shows procurement component information 802 obtained by updating the procurement component information 802 before update shown in FIG. 6-3-4 in S280.

  Upon completion of the processing of S280, procurement parts information (order number: H00001, part number: 888-888, order number: 100, delivery date: 20061001, supplier: A01, transportation company code: BBB, vehicle number: 555-0101, The transporter code: Y-001, loading instruction number: S000000123, status: accepted) is transmitted to the RFID 30 embedded in the delivery note and the orderer management terminal 40 (S285).

  The information is received by the delivery form embedded RFID 30 and the orderer management terminal 40 via the network (S310, S430), and the delivery form embedded RFID 30 writes the received information in the storage area of the RFID 30 (S315). In 40, it is displayed on the screen (S435).
