[3. Operation of Information Processing System 1]
Next, the operation of the information processing system 1 according to one embodiment of the present invention will be described with reference to FIGS.

  FIG. 7 is a schematic diagram showing an outline of an example of the manufacturing process. FIG. 8 is a sequence diagram illustrating an operation example of the information processing system 1. FIG. 9 is a schematic diagram illustrating an example of a communication packet. 10 to 12 are schematic diagrams showing examples of display on the terminal device 20.

  First, as shown in FIG. 7, before the loading platform 40 to which the terminal device 20 is attached is brought into the place of the first manufacturing process, the terminal device is used by the reader 7 to rewrite (update) display data. Twenty codes 20a are read. Then, the information processing device 10 acquires the terminal ID of the terminal device 20. The information processing apparatus 10 reads the code 20a of the terminal device 20 in order to measure the timing of rewriting (updating) display data.

  The information processing system 1 confirms the state of the LED (step S1). Specifically, the information processing device 10 is based on the acquired terminal ID of the terminal device 20 in order to confirm which LED is lit in the second display unit 24 of the terminal device 20 to be rewritten. The lighting information of the second display unit 24 is acquired with reference to the display state management table of the display information DB 12c.

  Next, the information processing system 1 transmits an LED lighting command by infrared communication (step S2). Specifically, the information processing apparatus 10 transmits an LED lighting command indicating which LED is to be lit in the second display unit 24 to the terminal device corresponding to the terminal ID via the wireless device 5 of the infrared AP. Here, as shown in FIG. 9, the LED lighting command is a communication packet including a destination ID (terminal ID) for calling the terminal device 20, a transmission source ID, an LED lighting command code, and data. Sent. In addition, this data is data (an example of display data) which LED of the 2nd display part 24 is made to light.

  Next, the information processing system 1 receives an LED lighting command by infrared communication (step S3). Specifically, the called terminal device 20 receives an LED lighting command from the information processing device 10 via the infrared communication module 21b.

  Thus, the terminal device 20 functions as an example of a receiving unit that receives display data. The terminal device 20 functions as an example of a second rewrite information receiving unit that receives the second rewrite information.

  Next, the information processing system 1 determines whether or not the instruction code is an LED lighting instruction (step S4). Specifically, the terminal device 20 reads out the instruction code of the communication packet and determines whether or not it is an LED lighting instruction.

  Thus, the terminal device 20 functions as an example of a display rewrite determination unit that determines whether or not to rewrite the display using the display data.

  When the command code is an LED lighting command (step S4; YES), the information processing system 1 performs an LED lighting process (step S5). Specifically, the terminal device 20 turns on the designated LED (LED24 (LED2)) and turns on the other LED (LED24 (LED1)) as shown in FIG. 10 according to the data following the instruction code of the communication packet. Turns off. That is, the display is rewritten.

  Next, the information processing system 1 transmits a response (step S6). Specifically, the terminal device 20 transmits information indicating that the LED lighting process has ended to the information processing device 10 by infrared communication of the infrared communication module 21b. Note that the terminal device 20 may transmit information indicating that the LED lighting process has ended by wireless communication of the wireless module 21a.

  If the command code is not an LED lighting command (step S4; NO), the terminal device 20 transmits a response and ends the process.

  Next, the information processing system 1 receives a response (step S7). Specifically, the information processing apparatus 10 transmits information indicating that the LED lighting process has ended from the terminal apparatus 20 by infrared communication.

  Next, the information processing system 1 determines whether the lighting has succeeded (step S8). Specifically, the information processing apparatus 10 determines whether there is a response within a certain time.

  If the lighting is successful (step S8; YES), the display state management table is updated (step S9). Specifically, the information processing apparatus 10 updates the LED lighting state of the terminal ID to be rewritten in the display state management table of the display information DB 12c.

  Next, the information processing system 1 wirelessly transmits a screen rewrite command (step S10). Specifically, the information processing apparatus 10 transmits a screen rewriting command including rewritten display data to the terminal device corresponding to the terminal ID via the wireless device 5 of the wireless AP. Here, as shown in FIG. 9, the screen rewriting command is a communication composed of a destination ID (terminal ID) for calling the terminal device 20, a transmission source ID, a command code of the screen rewriting command, and display data. Sent by packet.

  Next, the information processing system 1 receives a screen rewriting command by wireless communication (step S11). Specifically, the called terminal device 20 receives a screen rewrite command from the information processing device 10 via the wireless module 21a.

  Thus, the terminal device 20 functions as an example of a receiving unit that receives display data.

  Next, the information processing system 1 determines whether it is a screen rewrite command (step S12). Specifically, the terminal device 20 reads the instruction code of the communication packet and determines whether it is a screen rewriting instruction.

  Thus, the terminal device 20 functions as an example of a display rewrite determination unit that determines whether or not to rewrite the display using the display data.

  If it is a rewrite command (step S12; YES), the information processing system 1 performs a screen rewrite process (step S13). Specifically, the terminal device 20 displays data following the instruction code of the communication packet on the first display unit 23 as display data. For example, as shown in FIG. 10, an image in which the display content of the first display unit 23 is rewritten is displayed. The lot number, the instruction content, and the position of the mark 23a are changed.

  As shown in FIG. 10, even if the screen is rewritten, the second display unit 24 (LED2) and the mark 23a displayed on the first display unit 23 are in positions corresponding to each other. In this case, it is assumed that there is no abnormality in the display. In this way, the first rewrite information displayed on the first display means and the second rewrite information displayed on the second display means are displayed at positions corresponding to each other.

  On the other hand, when there is a problem with the wireless communication of the wireless module 21a and the screen rewriting has failed, when the first display unit 23 itself has a failure and the screen rewriting has failed, or between the system control unit 27 and the first display unit 23 When the screen rewriting fails due to a failure such as disconnection between them, or when the screen rewriting fails due to insufficient power, the position of the mark 23a displayed on the first display unit 23 changes as shown in FIG. Absent. In this case, since only the lighting position of the LED of the second display unit 24 is changed, the position of the mark 23a does not correspond, and it is immediately determined that something is abnormal visually.

  Further, when there is a trouble in the infrared communication of the infrared communication module 21b, when there is a failure in the second display unit 24, or when there is a failure such as a disconnection between the system control unit 27 and the second display unit 24. Or, when the power is insufficient, as shown in FIG. 12, the lighting position of the LED of the second display section 24 does not change, and the position of the mark 23a displayed on the first display section 23 changes. As described above, since only the position of the mark 23a is changed, the position of the lighting position of the LED of the second display unit 24 does not correspond, and it is immediately determined that something is abnormal visually.

  Next, the information processing system 1 transmits a response (step S14). Specifically, the terminal device 20 transmits information indicating that the screen rewriting process is completed to the information processing device 10 by wireless communication of the wireless module 21a. Note that the terminal device 20 may transmit information indicating that the screen rewriting process is completed by infrared communication of the infrared communication module 21b.

  If the instruction code is not a screen rewrite instruction (step S12; NO), the terminal device 20 transmits a response and ends the process.

  Next, the information processing system 1 receives a response (step S15). Specifically, the information processing apparatus 10 transmits information indicating that the screen rewriting process is completed from the terminal apparatus 20 by wireless communication.

  Next, the information processing system 1 determines whether the screen rewriting is successful (step S16). Specifically, the information processing apparatus 10 determines whether there is a response within a certain time.

  When lighting is not successful (step S8; NO), the information processing system 1 notifies an error (step S17). When the screen rewriting is not successful (step S16; NO), the information processing system 1 notifies an error (step S17). Specifically, if there is no response for a certain period of time, the information processing apparatus 10 times out, displays an error message on the display unit 13 or the like, and notifies the administrator of the error.

  As shown in FIG. 7, before the loading platform 40 to which the terminal device 20 is attached is carried into the place of the first manufacturing process, the importer positions the mark 23 a on the first display unit 23 of the terminal device 20. Then, the lighting position of the LED on the second display unit 24 is compared to check whether the display on the terminal device 20 has been rewritten.

  If there is no abnormality after confirmation, the loading platform 40 to which the terminal device 20 is attached is moved to the device 33 in each process, and the product P is manufactured in the device 33. The manufactured product P is unloaded, the loading platform 40 to which the terminal device 20 is attached returns to the place of the first manufacturing process, and the code 20 a of the terminal device 20 is read by the reader 7.

  As described above, according to the present embodiment, it is determined whether or not to rewrite the display by the received display data. When the display is rewritten by the display data, the mark 23a (first rewrite) is displayed on the first display unit 23. Information) and displaying the second rewrite information on the second display unit 24 at a position where the display surface of the first display unit 23 can be visually recognized, thereby comparing the first rewrite information with the second rewrite information. It is displayed at a possible position, and it can be easily recognized whether or not the display content has been rewritten.

  By displaying a plurality of systems, it is possible to easily recognize whether or not the display content has been rewritten even if one of the systems breaks down. In particular, since the screen remains on the screen even when the power is turned off, it is difficult to determine the abnormality visually. However, as a separate display, the electronic paper includes a second display unit 24 that turns on the LED, and displays the second rewrite information. By displaying, it can be easily recognized whether or not the display content has been rewritten.

  When the mark 23a displayed on the first display unit 23 and the second rewrite information (LED display switching, display position) displayed on the second display unit 24 are displayed at positions corresponding to each other. The correspondence relationship makes it easy to check for abnormalities and reduces oversight.

  When the display part (LED) of the 2nd display part 24 is installed in the outer edge part of the display surface of the 1st display part 23, the mark 23a displayed on the display surface of the 1st display part 23, and a 2nd display part 24 display parts can be compared more easily, and it can be easily recognized whether or not the display contents are rewritten. In particular, when the mark 23 a is displayed at a position near the outer edge of the display surface of the first display unit 23, it becomes easier to compare.

  Further, when a second rewrite information receiving means for receiving the second rewrite information is further provided, an abnormality can be detected even when there is a trouble in one communication.

Next, a modified example of the terminal device 20 will be described with reference to FIGS. 13 and 14.
FIG. 13 is a schematic diagram illustrating a first modification of the terminal device. FIG. 14 is a schematic diagram illustrating a second modification of the terminal device.

  As shown in FIG. 13, the number of display parts of the second display unit 24 may be three or more. For example, the LED at the position corresponding to the process number is turned on for each process. The display position of the mark 23a on the first display unit 23 is also moved according to the process number.

  Further, as shown in FIG. 14, the mark 23 a of the first display unit 23 may indicate a number such as a process number. At this time, if a process number is described below the display portion of the second display section 24, it becomes easier to compare with the process number of the mark 23a.

  In the present embodiment, the information processing apparatus 10 transmits the LED lighting command for the second display unit 24 by infrared communication and the screen rewrite command for the first display unit by wireless communication.
