It should be noted that not all devices have these configurations, and it is only necessary to provide necessary devices.

  FIG. 3 is a flowchart showing a preparation process by the parent terminal 001 in the embodiment of the present invention.

  3 is a process in which the CPU 201 of the parent terminal 001 reads and executes a predetermined control program.

  In step S101, the CPU 201 of the base terminal 001 acquires a master from an external storage device such as a connected USB memory.

  The master in this embodiment is information on a product ID and its unit price, information on a credit card number and type, information on currency, information on a product loaded in a cart for in-flight sales, etc. Contains information needed to sell the product.

  In step S102, CPU 201 of parent device terminal 001 transmits a communication start signal to the connected child device terminal by infrared communication. The communication start signal includes information to start communication from now on and an instruction to collect various data held by each slave terminal in the master terminal 001. In the present embodiment, it is assumed that HTID (mobile terminal identification information), the date of the master that each slave terminal has (information about when the master is held), and the program version of each slave terminal are collected. To do.

  In step S103, it is determined whether or not data such as HTID (mobile terminal identification information) and a master date (information on when the master is held) held by each mobile terminal is received from the connected slave terminal. . An example of data such as HTID in each portable terminal is shown in FIG.

  If data such as HTID has been received (step S103: YES), the process proceeds to step S104.

  If data such as HTID has not been received (step S103: NO), it waits for reception of HTID or the like.

  In addition, when it does not receive even if the predetermined time passes after transmitting a communication start signal, you may comprise so that a communication failure may be notified as a communication error.

  In step S104, the CPU 201 of the parent device terminal 001 specifies a portable terminal (master device terminal or any slave device terminal) having the latest date master.

  Specifically, the master date of each child device terminal received in step S103 is compared with the master date of parent device terminal 001 (own device), and the portable terminal with the latest master date (having the newest master) is identified. To do. The master date in base unit terminal 001 is the master date acquired from the external storage device in step S101.

  In step S105, CPU 201 of base unit terminal 001 transmits an instruction to share the master data stored in the mobile terminal to all the mobile terminals connected to the mobile terminal identified in step S104. To do.

  If there are multiple mobile terminals with master data with the latest master date, specify the mobile terminal that is the sharing source and give instructions so that the number of communications is minimized when sharing the master data. put out. Specifically, this will be described later with reference to FIG.

  If it is determined that the master terminal 001 has master data having the latest master date, the master data held by the own machine is transmitted.

  In step S106, CPU 201 of base unit terminal 001 determines whether or not the master can be shared by all connected portable terminals.

  Specifically, the determination is made based on whether or not the latest master has been transferred to the master terminal 001.

  When sharing of the master is completed (step S106: YES), the process proceeds to step S107.

  When the master sharing is not completed (step S106: NO), the process waits until the master sharing is completed.

  In step S107, CPU 201 of base unit terminal 001 transmits an end message to each connected mobile terminal. This end message is a signal that the sharing of the master is completed and the communication is ended.

  When the end message is returned (step S108: YES), the processing shown in this flowchart is ended.

  FIG. 4 is a flowchart showing the preparation processing by the slave terminals (slave terminal 002 to slave terminal 004) in the embodiment of the present invention.

  Note that the processing shown in the flowchart of FIG. 4 is processing in which the CPU 201 of the slave terminal reads and executes a predetermined control program.

  In step S201, the CPU 201 of the child device terminal receives the communication start signal transmitted from the parent device terminal 001 from the adjacent portable terminal (side closer to the parent device terminal).

  In step S202, the CPU 201 of the slave terminal prepares for communication.

  In step S203, the CPU 201 of the child device terminal determines whether or not the own device is located at the end of the connected portable terminal (in this embodiment, whether or not the own device is the child device terminal 004). to decide).

  As a method for determining whether or not the terminal is located at the end, it is possible to determine whether there is a slave terminal on the side opposite to the master terminal 001 (whether or not communication is possible). It is also possible to use a method for setting in advance the end.

  If it is determined that it is located at the end (step S203: YES), the process proceeds to step S207.

  If it is determined that it is not located at the end (between other portable terminals. In this embodiment, the slave terminal 002 or the slave terminal 003) (step S203: NO), the process proceeds to step S204. To do.

  In step S204, the CPU 201 of the child device terminal transfers the communication start signal received in step S201 to the adjacent child device terminal. Note that the portable terminal that is the transfer destination in step S204 is the portable terminal that is not the transmission source of the communication start signal received in step S201 among the connected portable terminals. That is, it is a mobile terminal on the opposite side to the parent terminal 001.

  In step S205, CPU 201 of the slave terminal determines whether data such as HDIT has been received from another slave terminal.

  If it is determined that it has been received (step S205: YES), the process proceeds to step S206.

  If not received (step S205: NO), it waits until it is received.

  In step S206, the CPU 201 of the slave terminal adds its own data to the data received in step S205 and transmits it to the adjacent portable terminal. Here, the adjacent mobile terminal is a mobile terminal that is a transmission source of the communication start signal received in step S201. That is, it is a mobile terminal on the base terminal 001 side.

  The data such as HTID in step S205 is illustrated in FIG.

  In step S207, the CPU 201 of the child device terminal transmits data such as its own HTID to the portable terminal that is the transmission source of the communication start signal received in step S201. That is, since the own device is at the end, there is no need to transfer the communication start signal, and the HTID information of the own device is sent back next.

  The processes in steps S201 to S207 described above correspond to the process shown in FIG. 7 (the first round of the preparation process). By executing this process, information such as the HTID of the connected mobile terminal is collected in the parent device terminal 001.

  In step S208, CPU 201 of the slave terminal determines whether or not the master sharing instruction transmitted from master terminal 001 in step S105 has been received.

  If a master sharing instruction has been received (step S208: YES), the process proceeds to step S212.

  If the master sharing instruction has not been received (step S208: NO), the process proceeds to step S209.

  In step S209, the CPU 201 of the child device terminal determines whether or not the latest master has been received. In other words, if a slave unit terminal having the latest master is located closer to the master unit terminal than the own unit, the master sharing instruction is not transferred before the slave unit terminal having the latest master. Since the master is transmitted from the slave terminal having the master, it is determined whether or not the master is received.

  If it is determined that the master has been received (step S209: YES), the process proceeds to step S210.

  If it is determined that the master has not been received (step S209: NO), the process proceeds to step S208, and waits again until a master sharing instruction or a master is received.

  In step S210, CPU 201 of the slave terminal stores the master received in step S209 in its own storage area.

  In step S211, the CPU 201 of the child device terminal transfers the master received in step S209.

  In step S211, if the own device is located at the end, it is transferred to the master transmission source (base terminal 001 side) received in step S209, and if it is not the end, it is not the transmission source. Transfer to the next portable terminal (on the opposite side to the parent terminal 001).

  In step S221, the CPU 201 of the child device terminal determines whether or not it is located at the end of the portable terminal to which the own device is connected.

  When it is determined that it is an end (step S221: YES), the processing shown in this flowchart is terminated.

  If it is determined that it is not an end (step S221: NO), the process proceeds to step S222.

  In step S222, the CPU 201 of the child device terminal receives the master transferred from the child device terminal opposite to the parent device terminal (returned transfer).

  In step S223, the CPU 201 of the child device terminal transfers the master received in step S222 to the adjacent portable terminal (parent device terminal 001 side).

  In step S223, the transferred master is merely received, and the received master is not stored.

  In step S212, the CPU 201 of the child device terminal analyzes the master sharing instruction and determines whether or not the own device is a portable terminal having the latest master.

  If it is determined that the own device is a portable terminal having the latest master (step S212: YES), the process proceeds to step S217.

  If it is determined that the own device is not a portable terminal having the latest master (step S212: NO), the process proceeds to step S213.

  In step S213, the CPU 201 of the child device terminal transfers the master sharing instruction received in step S208 to the adjacent child device terminal (the side opposite to the parent device terminal 001).

  In step S214, CPU 201 of the slave terminal determines whether or not a master has been received. That is, this is a case where the slave terminal located on the opposite side to the master terminal 001 has the latest master, and in step S214, it is determined whether or not the one that has been transferred back is received.

  If the master is received (step S214: YES), the process proceeds to step S215.

  If the master has not been received (step S214: NO), the process waits until the master is received.

  In step S215, the CPU 201 of the slave terminal stores the master received in step S214 in the storage area.

  In step S216, CPU 201 of the slave terminal transfers the master received in step S214 to the adjacent mobile terminal. The transfer destination is a mobile terminal (a mobile terminal on the base terminal 001 side) that is not the master transmission source.

  Next, a process when it is determined in step S212 that the own device has the latest master will be described.

  In step S217, the CPU 201 of the slave terminal transmits the master held by the slave terminal to the adjacent portable terminal.

  When the mobile terminal that is the transmission destination is located at the end of the mobile terminal to which the own device is connected (in the case of the child device terminal 004 in this embodiment), the master sharing instruction received in step S208. It is a mobile terminal that is the transmission source. If it is not an end, it is a portable terminal (the side opposite to the parent terminal 001) that is not the transmission source of the master sharing instruction received in step S208.

  In step S218, the CPU 201 of the child device terminal determines whether or not it is located at the end of the portable terminal to which the own device is connected.

  If it is determined that it is an end (step S218: YES), the processing shown in this flowchart is terminated.

  If it is determined that it is not an end (step S218: NO), the process proceeds to step S219.

  In step S219, the CPU 201 of the slave terminal receives the master transferred from the slave terminal on the opposite side of the master terminal (returned transfer).

  In step S220, the CPU 201 of the child device terminal transfers the master received in step S219 to the adjacent portable terminal (parent device terminal 001 side).

  In step S219, the master that has been transferred (or transmitted from the master terminal) is simply received, and the received master is not stored.

  The processes in steps S208 to S223 described above correspond to the processes shown in FIGS. 9 and 10 (the second round of the preparation process). By executing this process, the latest master is shared by all connected portable terminals.

  FIG. 5 is a flowchart showing the counting process by the base terminal 001 in the embodiment of the present invention.

  Note that the processing shown in the flowchart of FIG. 5 is processing in which the CPU 201 of the parent terminal 001 reads and executes a predetermined control program.

  In step S301, the CPU 201 of the parent device terminal 001 transmits a sales data collection instruction to the connected child device terminals in order to collect sales data of the connected child device terminals.

  In step S302, CPU 201 of parent device terminal 001 determines whether or not sales data transmitted from the connected child device terminal has been received.

  If received (step S302: YES), the process proceeds to step S303.

  If not received (step S302: NO), it waits until it is received. It should be noted that, even if a predetermined time elapses, if it is not received, an error notification may be issued as a communication error.

  In step S303, the sales data of each child device terminal and parent device terminal (own device) received in step S302 is totaled.

  The table shown in FIG. 14 is a diagram illustrating an example of sales data in each mobile terminal. Further, the table shown in FIG. 15 is a diagram showing sales data as a result of aggregation by the parent device terminal 001 in step S303.

  The sales data shown in FIG. 14 includes “product ID”, “unit price”, “quantity”, and “total”. The data items constituting the sales data are not limited to these, and other items may be included, and it is not essential that all items shown in FIG. 14 are included. .

  In this embodiment, sales data is aggregated as an example. However, the present invention can be applied to any data aggregation process as long as the data is aggregated in each mobile terminal. It is.

  FIG. 6 is a flowchart showing the counting process by the slave terminal in the embodiment of the present invention.

  Note that the processing shown in the flowchart of FIG. 6 is processing in which the CPU 201 of the slave terminal reads and executes a predetermined control program.

  In step S401, the CPU 201 of the child device terminal receives the sales data collection instruction transmitted from the parent device terminal 001 in step S301.

  In step S402, the CPU 201 of the child device terminal determines whether or not it is located at the end of the portable terminal to which the own device is connected.

  If it is determined that it is located at the end (step S402: YES), the process proceeds to step S406.

  If it is determined not to be located at the end (step S402: NO), the process proceeds to step S403.

  In step S403, the CPU 201 of the slave terminal transfers the sales data collection instruction received in step S401 to the slave terminal connected adjacently.

  Note that the transfer destination of the sales data collection instruction is a portable terminal (a slave terminal opposite to the parent terminal) that is not the transmission source of the sales data collection instruction received in step S401.

  In step S404, the CPU 201 of the slave terminal determines whether sales data has been received from another mobile terminal.

  When sales data is received from another portable terminal (step S404: YES), the process proceeds to step S405.

  When sales data is not received (step S404: NO), it waits until sales data is received.

  In step S405, the CPU 201 of the child device terminal adds the sales data in its own device to the sales data of the other mobile terminal received in step S404, and transmits it to the adjacent mobile terminal.

  In step S406, the CPU 201 of the child device terminal transmits the sales data of the own device to the adjacent portable terminal.

  That is, since the own device is located at the end, there is no need to transfer the sales data collection instruction. For this reason, only the process of transmitting the sales data of the own device to the portable terminal (master terminal 001 side) that is the transmission source of the sales data collection instruction is performed.
