Description

  The present invention relates to a chemical loading information system in a chemical manufacturing plant.

  In a manufacturing plant for chemical products or the like, a plurality of types of products are manufactured. In addition, products often have different guaranteed purities requested by customers. The manufactured chemicals need to be loaded into a predetermined transportation vehicle at an appropriate timing for each type and grade according to the shipping destination. Also, after loading, it is necessary for the driver of the transport vehicle to obtain a document in a format corresponding to the shipping destination.

  Since the shipping schedule is frequently changed according to the order status from the customer, it is desired that the latest information be shared between the driver and the manufacturing plant. Order status may change many times a day.

  Drivers often visit a manufacturing plant several times a day to load similar products. For this reason, when entering a manufacturing plant, various items are checked with an operator who is resident in the plant to prevent a mistake in loading. Items to be confirmed include the type of product to be loaded, the location of loading, the timing of loading, the type of document to be obtained by the driver, and the like. These information are often changed immediately before the start of work. For this reason, when the driver of the transport vehicle arrives at the manufacturing factory, the driver checks by telephone communication with the operator of the manufacturing plant.

  In Patent Literature 1, in a tank lorry shipping management system, cross-checking between shipping-related information input to an IC tag carried by a driver of a tank lorry and information held by a computer installed in a facility for loading chemicals into the tank lorry. A method for preventing an erroneous operation or the like by doing so is disclosed. The driver inputs the shipping-related information to the IC tag possessed by the driver every time the shipment is carried out by manually referring to the data of the host computer.

JP 2004-51139 A

  In a conventional telephone call, the driver and the person in the central monitoring room check the information on the loading of chemicals. However, misunderstandings may occur during the conversation, which causes loading of the wrong product. In addition, there is a problem that it takes time and effort to confirm, and the progress of other tasks of the person in charge of the central monitoring room is hindered. In addition, the task of grasping frequently updated loading information and sharing the latest information between the driver and the manufacturing plant is cumbersome, and it takes time to confirm that loading is performed accurately. There is. It is easy to make mistakes over the telephone.

  Further, in Patent Document 1, it is necessary to rewrite the shipping related information of the IC tag by a manual operation of the driver every shipment. In manual operation, erroneous input may occur. In addition, a rewritable IC tag needs to be prepared, and a conventional tag whose data cannot be rewritten cannot be used. Further, since the driver can access all shipping related information stored in the host computer, a security problem arises. If the loading information is updated frequently, the information owned by the driver and the information on the manufacturing plant side do not match, so that cross-check cannot be performed.

(Loading operation flow)
Hereinafter, the flow of the loading operation of the driver will be described with reference to FIG. The loading schedule created in advance is stored in the loading schedule storage unit 21 and the local memory 31. The loading schedule on the manufacturing plant side includes a list of vehicles coming to the chemical manufacturing plant for chemical loading. The loading schedule storage unit 71 of the transportation company stores only a list of vehicles belonging to the transportation company. The transportation company informs the driver of the loading schedule and distributes the RFID cards one-to-one with the vehicles.

  On the RFID card, as driver information, information on the vehicle such as the car number, the name of the chemical loaded, information on the loading amount (loading amount), information on the transportation company such as the name of the transportation company, the identification number of the transportation company, information on other vehicles, information on the transportation destination, The company name and its address may be recorded.

  The loading schedule is a list of information on vehicles scheduled to visit the plant for loading chemicals and a list of visiting schedules of the vehicles. The vehicle information is information about the transportation company such as a vehicle number, a transportation company name, and a transportation company identification number. The visit schedule includes a car number, a loading time, a loading chemical name, a loading amount, information on an analysis table, a destination company name and its address, and the like.

  In addition, the driver can carry the RFID card, but when the driver takes turns driving in one vehicle, it can be stored in the vehicle. An RFID card can be placed in a plant, and when the driver arrives, the corresponding RFID card can be taken out and held over a tag reader. At this time, in order to prevent the RFID card from being confused, the input of a preset user ID and password can be combined with the reading by the tag reader. Furthermore, even in the case where the RFID card is lost, even if the RFID card is not present, if the predetermined information is input, the setting can be set to perform the same treatment as when the RFID card is held over, for example, a user ID, a password, By inputting the vehicle number, it may be used as an alternative to the RFID card.

  First, the transportation company's vehicle comes to the manufacturing plant. The driver holds the RFID card over the touch panel 35, and the tag reader 36 reads the unique ID of the RFID card and driver information (for example, vehicle number) (step S1). As another embodiment, the tag reader 36 may read the unique ID of the RFID card as the driver information.

Next, the schedule matching unit 32 determines whether or not the driver information or the unique ID of the RFID card is included in the loading schedule (Step S2). If the driver information or the unique ID of the RFID card is not included in the loading schedule, a screen indicating that the vehicle is not scheduled to be loaded is displayed on the touch panel 35 as shown in FIG. 3E (step S2-1). ). In this case, the driver contacts his / her transportation company (step S2-2). In other words, the driver is notified on the loading confirmation interface that there is no loading scheduled, and the loading operation cannot be continued (see, for example, FIG. 3E). Thus, it is possible to prevent loading of the chemicals to be shipped to the wrong vehicle.
In step S2-3, the driver acquires the latest loading schedule from the shipping company, and changes the loading schedule by a predetermined operation from the input screen (S2-3). If the change operation has not been performed, the operation is stopped (S2-4). If the change operation has been performed, the process returns to step S2, and it is determined whether the driver information is included in the loading schedule.
For example, there is a case where the driver arrives with an instruction from the transportation company in advance for the latest order status or dispatch information, but the order status or the like is not reflected in the loading schedule and does not match. The driver can update the loading schedule by contacting the shipping company (S2-2) and reporting from the shipping company to the operator managing the loading schedule server 2. "Communication with the shipping company" may be input (S2-3), and the determination in step S2 may be performed. Alternatively, the loading schedule may be compared with the driver information in the latest state by holding the RFID card again after the update (S2).

As described above, if the cause of the inability to collate is a mistake of the RFID card, the appropriate RFID card is scanned again, and the driver information and the loading schedule are collated. Thus, it is possible to prevent the RFID cards from being mixed up.
In some cases, the updated loading schedule data is not transmitted to the shipping company. In the present embodiment, the loading schedule stored in the loading schedule server 2 is updated when the order content of the product (product name, order quantity, delivery time, etc.) is changed. When there is an update, the update information is automatically transmitted to the receiving terminal 3 and the transport vehicle management server 7. As a result, it is possible to quickly change the arrangement of the transport vehicles due to the change in the order content and to transmit the updated information to the driver.

  If the driver information or the unique ID of the RFID card is included in the loading schedule, the loading schedule confirmation screen shown in FIG. 3A is displayed, and the driver is requested to confirm it (step S3). The contents displayed on the loading schedule confirmation screen include information recorded on the RFID card (vehicle number, chemicals, etc.), scheduled loading time in the loading schedule, required number of analysis tables for products, analysis table (General, special), but other items can also be displayed. The driver touches the “OK” button when the loading schedule (for example, scheduled shipping time, number of today, type of analysis table, etc.) transmitted from the shipping company matches the content of the loading schedule confirmation screen. I do. (Step S4). In the case of “OK”, the approval requesting unit 34 requests the loading approval determining unit 44 for the loading approval (step S5).

If there is a difference in the contents displayed on the loading schedule confirmation screen (for example, scheduled time, number of analysis tables, type), it can be corrected. Since the loading may be performed a plurality of times on the same day, the driver can select a schedule to be performed from a plurality of loading schedules.
For example, when the driver touches the “time change request button”, for example, when the loading schedule transmitted from the shipping company and the scheduled shipping time are different, the screen of the today's all loading schedule shown in FIG. 3B is displayed. On this screen, the driver touches an appropriate loading “selection button”. When the input of the “select button” is received, the approval requesting unit 34 requests the loading approval from the packing approval determining unit 44 (step S5). As another embodiment, after touching the “select” button, the screen may be switched to the previous screen (FIG. 3A), and here, “OK” may be touched to execute the approval request.
In addition, when confirming the analysis table or when the display in the column of the analysis table is different from the loading schedule transmitted from the shipping company, the driver touches the “analysis table change request button” and the driver touches the analysis table shown in FIG. Switch to a screen where you can change the type and number of analysis tables. When the "OK" button is touched after receiving the input relating to the change of the analysis table, the approval requesting unit 34 requests the loading approval determining unit 44 for the loading approval (step S5). As another embodiment, the configuration may be such that after touching the “OK” button after the input relating to the change of the analysis table, the screen is switched to the previous screen (FIG. 3A), and “OK” is touched here to execute the approval request.
If the driver is not confirmed, the operation is stopped (step S4-1). The driver contacts the plant operator or the shipping company.

Next, the loading approval determination unit 44 determines whether to approve the approval request sent from the approval request unit 34 based on the loading approval rule read from the loading approval rule storage unit 41. .
In the present embodiment, as a first step, the loading approval determining unit 44 sorts between automatic approval and manual approval based on the driver information and the information on the loading schedule (step S6). For example, when a predetermined customer (delivery destination of a chemical product) has necessary documents for shipping a chemical product, an automatic approval process is performed. In other cases, a manual approval process is performed.

  As a second step in the automatic approval process, when the difference between the scheduled loading time checked in the loading schedule and the time when the driver information is obtained or the current time is within a predetermined range, the automatic loading is approved (step S7). On the other hand, if the difference is not within the predetermined range, the automatic loading is rejected and a manual approval process is performed. As another embodiment of the second step, in the automatic approval process, automatic loading is approved when the chemical inventory is equal to or more than a predetermined amount or the loading amount, and when the chemical inventory is less than a predetermined amount or less than the loading amount. The automatic loading may be rejected and the process may be switched to a manual approval process. If either one of the above-mentioned conditions and the condition described later is satisfied, the automatic loading may be rejected and a manual approval process may be performed.

  When the automatic loading is approved, a command to the effect that the automatic loading has been approved is transmitted from the loading approval server 4 to the receiving terminal 3, and the touch panel 35 displays a loading approval guidance screen shown in FIG. 3D. (Step S8). The driver touches an “OK” button as a confirmation input (step S9). The driver goes to the loading position indicated in the information of the loading approval guidance and loads (fills) the chemical into the transport vehicle.

  On the other hand, in the case of the manual approval process, the driver information and the loading schedule are displayed on the monitor of the central control room, and the plant operator confirms (step S11). In the manual approval process, the plant operator determines whether to approve or reject the shipment (step S12). If the operator permits, the process proceeds to step 8. For example, when it is necessary to output necessary documents such as an analysis table, readjustment / change of the loading schedule, etc., the plant operator outputs necessary documents, adjusts the schedule, etc., and then approves loading. In step S8, the loading approval guidance is displayed. When the operator does not permit, the process proceeds to step S13. For example, when it is necessary for the plant operator to directly contact the driver, reject the loading approval and display the fact on the touch panel 35 (step S13) to notify the driver. Then, the driver notifies the plant operator (step S14). In such a case, a microphone and a speaker for inputting and outputting audio may be incorporated in the receiving terminal 3.

  In another embodiment, the loading approval may be automatically rejected in an automatic approval process. For example, it may be automatically rejected due to a timeout of input in the loading approval guidance. In this case, the receiving terminal 3 may determine the timeout, and the loading approval server 4 may determine the timeout. The touch panel 35 displays a loading approval rejection screen (see FIG. 3F). The driver may touch the "back" button as input for the confirmation and the driver may contact the plant operator in the control room.

  In step S1, the loading approval is also rejected when loading is not permitted due to a mistake in the RFID card or the expiration of the maintenance period of the vehicle container. Also in this case, the screen of FIG. 3F is displayed on the touch panel.

The information of the loading approval guidance includes the place where chemicals are filled into the vehicle, the number of the filling equipment, the filling procedure, the presence or absence of documents required for shipping, and the acquisition method. Digitization of this information, which was conventionally communicated orally, prevents incorrect filling locations, incorrect types of chemicals to be filled, incorrect filling procedures, and incomplete documents when delivering chemicals to the destination. can do. If not approved, the loading approval interface displays that fact, so that the loading operation can be stopped.
If the work time is different from the planned schedule by making a decision based on the loading approval rule, or if the person in charge of the central monitoring room needs to manually print and prepare the required documents, etc. Can be a manual approval process. As a result, the driver and the person in charge of the central monitoring room can directly contact each other, and can flexibly respond to sudden schedule changes and the like.

  The determination result of the loading approval or the loading rejection can be recorded in a storage (not shown) of the loading approval server 4. The approval or rejection of the loading is transmitted from the loading approval server 4 to the receiving terminal 3 via the network connection, and the approval or rejection is displayed on the touch panel 35 or output as a voice message by the loading approval interface 38 of the receiving terminal 3. Is also good. If the shipment is approved, guidance information for the driver may be displayed together. The guidance information may include a chemical loading location, a loading equipment number, a method of receiving necessary documents, and the like.

As RFID tags, three types of Mifare Classic NFC card and NXP NTAG213 NFC token were used.
As a receiving terminal, a Sony Xperia Z4 tablet equipped with an NFC sensor was used.
The loading schedule server 2 and the loading approval / server 4 used a cloud service storage and accessed from the tablet using mobile Internet (3G / LTE) through an encrypted connection.
