Yes. That is, it is the structure by which the adjacent portable terminal was connected so that communication was possible.

  In the present embodiment, a configuration using four mobile terminals (a master terminal and a slave terminal) is described, but the present invention is applicable regardless of the number of mobile terminals.

  In the present embodiment, communication is performed using infrared rays. However, the communication method between portable terminals is not limited to infrared communication, and any method may be used.

  Hereinafter, the hardware configuration applicable to the mobile terminal shown in FIG. 1 will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, the ROM 203 or the external memory 211 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs are stored.

  A RAM 202 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program necessary for execution of processing from the ROM 203 or the external memory 211 into the RAM 202 and executing the loaded program.

  An input controller 205 controls input from the input device 209 or the like. A video controller 206 controls display on a display device 210 such as a liquid crystal display. The display device is not limited to a liquid crystal display, and may be a CRT display or the like. These are used by clients as needed.

  A memory controller 207 is connected to the hard disk (HD), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, etc. via an adapter. The access to the external memory 211 such as a compact flash (registered trademark) memory is controlled.

  Various programs that operate on the hardware are recorded in the external memory 211 and are executed by the CPU 201 by being loaded into the RAM 202 as necessary.

The printer controller 212 controls a printing machine such as a thermal dot line type printer 213.

  The scanner controller 214 controls a discriminator such as the scanner 215.

  Further, various data and various tables used by the program according to the present invention are stored in the external memory 211, and detailed description thereof will be described later. It should be noted that not all devices have these configurations, and it is only necessary to provide necessary devices.

  Next, with reference to the flowchart shown in FIG. 3, the data totaling process by the parent terminal 001 in the embodiment of the present invention will be described.

  Note that the processing shown in the flowchart of FIG. 3 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. 15 is a diagram illustrating an example of sales data in each mobile terminal. Further, the table shown in FIG. 16 is a diagram showing the sales data as a result of aggregation by the parent terminal 001 in step S303.

  The sales data shown in FIG. 15 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 of the items shown in FIG. 15 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.

  Next, the data totaling process by the handset terminal will be described using the flowchart shown in FIG.

  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 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. Therefore, only the process of transmitting the sales data of the own device to the portable terminal (master device terminal 001 side) that is the transmission source of the sales data collection instruction is performed.

  FIG. 5 is a sequence diagram showing an overview of the data flow in the sales data collection process in the embodiment of the present invention.

  In step S501, a sales data collection instruction is transmitted from the parent device terminal 001 to the child device terminal 002 (corresponding to step S301 in FIG. 3).

  In step S502, the sales data collection instruction transmitted in step S501 is transferred from the slave terminal 002 to the slave terminal 003 (corresponding to step S403 in FIG. 4).

  In step S503, as in step S502, the sales data collection instruction is transferred from the child device terminal 003 to the child device terminal 004.

  In step S504, the sales data held by the handset terminal 004 is transmitted from the handset terminal 004 to the handset terminal 003 (corresponding to step S406 in FIG. 4).

  In step S505, the sales data transmitted from the slave unit terminal 004 in step S504 and the sales data held by the slave unit terminal 003 are transmitted from the slave unit terminal 003 to the slave unit terminal 002 (in step S405 of FIG. 4). Equivalent).

  In step S506, the sales data of child device terminal 004, child device terminal 003, and child device terminal 002 is transmitted from child device terminal 002 to parent device terminal 001.

  In the present embodiment, the processing in a case where the data stored in each mobile terminal is aggregated into one mobile terminal has been described, but the data stored in one mobile terminal is shared with other mobile terminals. The process is the same process.

  That is, for example, data is transmitted from the parent device terminal 001 to the child device terminal, and the child device terminal sequentially transmits the transmitted data to the adjacent child device terminal. The mobile terminal at the end sends back a message indicating that the data transmission is completed to the parent device terminal, and each child device terminal sequentially transmits information indicating the completion to the next portable terminal toward the parent device terminal. It will be a process.

  Through the above processing, for example, when data stored in one mobile terminal is shared by many mobile terminals, or when data distributed to many mobile terminals is to be aggregated, the mobile terminals are manually operated one by one. Can be realized without establishing communication by facing each other.

  Next, a description will be given of a coping method when a communication error occurs during execution of the communication method described above.

  Similar to the above-described embodiment, processing when four mobile terminals are connected in series will be described. However, the present invention is not limited to the case where four mobile terminals are connected, and is applicable when three or more mobile terminals are connected.

  FIG. 6 is a diagram illustrating a response when an error occurs in communication from the mobile terminal A to the mobile terminal B.

  When an error occurs in communication from the portable terminal A to the portable terminal B, it is possible that either the left communication unit 601 of the portable terminal A or the right communication unit 602 of the portable terminal B is out of order.

  Therefore, as shown in FIG. 6B, the mobile terminal A is arranged at the left end, and the arrangement of the mobile terminals is changed so that the mobile terminal B is arranged at the right end, thereby sharing data with all the mobile terminals ( Data transmission / reception).

  That is, a communication error is dealt with by arranging it so that a communication unit that may be broken may not be used.

  In this case, the portable terminal A detects that an error has occurred in communication with the portable terminal B, and the communication unit 601 on the left side of the portable terminal A or the communication unit 602 on the right side of the portable terminal B may be out of order. Is displayed on the display.

  Then, an error countermeasure is presented to the user by displaying the specific arrangement (the arrangement shown in FIG. 6B) to be displayed on the display unit (FIG. 7 as an example).

  FIG. 8 is a diagram illustrating a response when an error occurs in communication from the mobile terminal B to the mobile terminal C.

  When an error occurs in communication from the mobile terminal B to the mobile terminal C, it is possible that either the left communication unit 801 of the mobile terminal B or the right communication unit 802 of the mobile terminal C is out of order.

  Therefore, as shown in FIG. 8B, the mobile terminal B is arranged at the left end, and the arrangement of the mobile terminal is changed so that the mobile terminal C is arranged at the right end, thereby sharing data with all the mobile terminals ( Data transmission / reception).

  That is, a communication error is dealt with by arranging it so that a communication unit that may be broken may not be used.

  In this case, the mobile terminal B detects that an error has occurred in communication with the mobile terminal C, and the communication unit 801 on the left side of the mobile terminal B or the communication unit 802 on the right side of the mobile terminal C may be out of order. Is displayed on the display.

  Then, an error countermeasure is presented to the user by displaying on the display section (as an example, FIG. 9) what kind of arrangement should be made (the arrangement shown in FIG. 8B).

  FIG. 10 is a diagram illustrating a response when an error occurs in communication from the mobile terminal C to the mobile terminal D.

  When an error occurs in communication from the mobile terminal C to the mobile terminal D, it is possible that either the left communication unit 1001 of the mobile terminal C or the right communication unit 1002 of the mobile terminal D is out of order.

  Therefore, as shown in FIG. 10B, the mobile terminal C is arranged at the left end and the arrangement of the mobile terminals is changed so that the mobile terminal D is arranged at the right end, thereby sharing data with all the mobile terminals ( Data transmission / reception).

  That is, a communication error is dealt with by arranging it so that a communication unit that may be broken may not be used.

  In this case, the mobile terminal C detects that an error has occurred in communication with the mobile terminal D, and there is a possibility that the communication unit 1001 on the left side of the mobile terminal C or the communication unit 1002 on the right side of the mobile terminal D is out of order. Is displayed on the display.

  Then, an error countermeasure is presented to the user by displaying the specific arrangement (the arrangement shown in FIG. 10B) to be displayed on the display unit (FIG. 11 as an example).

  Next, processing executed by each mobile terminal in the present embodiment will be described with reference to FIG.

  The process illustrated in FIG. 17 is a process in which the CPU 201 of the mobile terminal reads and executes a predetermined control program.

  In step S1701, the CPU 201 of the mobile terminal accepts a data transmission instruction. Specifically, it corresponds to an instruction from the user. At this time, an instruction as to which data to transmit is also accepted. In addition, data reception from an adjacent mobile terminal also corresponds to a data transmission instruction. That is, the process of transmitting data is triggered by the reception of data from the adjacent mobile terminal. In this way, data is transmitted and transmitted sequentially.

  In step S1702, the CPU 201 of the mobile terminal transmits data according to the data transmission instruction received in step S1701.

  In step S1703, the CPU 201 of the mobile terminal determines whether the data transmission in step S1702 has been successful.

  If successful (step S1703: YES), the processing shown in this flowchart is terminated.

  If the data transmission has failed (step S1703: NO), the process proceeds to step S1704.

  In step S1704, the CPU 201 of the mobile terminal displays an arrangement change notification on the display unit (this corresponds to FIG. 7, FIG. 9, and FIG. 11).

At this time, an arrangement is presented in which the own device is at the left end, and the terminal located on the left side of the own device is positioned at the right end. Specifically, it is as described with reference to FIGS.
Then, the process shown in this flowchart is terminated.

  With the above processing, even if an error occurs in communication, data can be shared with all portable terminals.

  Next, as a second embodiment for handling when an error occurs, a mode in which a mobile terminal having a wide communication range is used will be described.

  FIG. 12 is a diagram illustrating a response when an error occurs in communication from the mobile terminal A to the mobile terminal B.

  When an error occurs in communication from the mobile terminal A to the mobile terminal B, it is possible that either the left communication unit 1201 of the mobile terminal A or the right communication unit 1202 of the mobile terminal B is out of order.

  In this case, the mobile terminal A attempts data communication with the mobile terminal C. When the communication with the mobile terminal C is successful, data communication is executed in the order of the mobile terminal A → the mobile terminal C → the mobile terminal D (FIG. 12B). That is, communication is performed by skipping the portable terminal B.

  Here, when communication with the mobile terminal C is not possible, it is possible that the communication unit 1201 on the left side of the mobile terminal A is out of order.

  Therefore, the portable terminal A displays that fact on the display unit, displays on the display unit that the communication should be performed again in the arrangement shown in FIG. 12C, and notifies the user.

  Note that the arrangement shown in FIG. 12C is the same as the arrangement shown in FIG.

  FIG. 13 is a diagram illustrating a response when an error occurs in communication from the mobile terminal B to the mobile terminal C.

  When an error occurs in communication from the mobile terminal B to the mobile terminal C, it is possible that either the left communication unit 1301 of the mobile terminal B or the right communication unit 1302 of the mobile terminal C has failed.

  In this case, the mobile terminal B attempts data communication with the mobile terminal D. When the communication with the mobile terminal D is successful, data communication is executed in the order of the mobile terminal A → the mobile terminal B → the mobile terminal D (FIG. 13B).

  On the other hand, when communication with the mobile terminal D is not possible, it can be considered that the communication unit 1301 on the left side of the mobile terminal B is out of order.

  In this case, the mobile terminal B transmits a message to the mobile terminal A to retransmit data to the mobile terminal C, and the mobile terminal A transmits data to the mobile terminal C (see FIG. 13 (C)).

  FIG. 14 is a diagram illustrating a response when an error occurs in communication from the mobile terminal C to the mobile terminal D.

  When an error occurs in communication from the mobile terminal C to the mobile terminal D, it is possible that either the left communication unit 1401 of the mobile terminal C or the right communication unit 1402 of the mobile terminal D is out of order.

  In this case, the mobile terminal C transmits a message to the mobile terminal B to retransmit data to the mobile terminal D, and data transmission from the mobile terminal B to the mobile terminal D is executed. (FIG. 14B).

  Next, processing executed by each mobile terminal in the present embodiment will be described with reference to FIG.

  The process illustrated in FIG. 18 is a process in which the CPU 201 of the mobile terminal reads and executes a predetermined control program.

  In step S1801, the CPU 201 of the mobile terminal accepts a data transmission instruction. Specifically, an instruction from a user, a data retransmission instruction from an adjacent terminal, data reception from an adjacent terminal, and the like are applicable. This process is the same process as step S1701 in FIG.

  In step S1802, the CPU 201 of the mobile terminal determines whether the data transmission instruction received in step S1801 is a data retransmission instruction. The data retransmission instruction corresponds to reception of a retransmission request in step S1813 in FIG.

  If it is a data retransmission instruction (step S1802: YES), the process proceeds to step S1803.

  If it is not a data retransmission instruction (such as a transmission instruction from a user or data reception from an adjacent mobile terminal, etc., step S1802: NO), the process proceeds to step S1804.

  In step S1803, the CPU 201 of the mobile terminal executes data transmission to the two adjacent mobile terminals. And the process of this flowchart is complete | finished.

  For example, in the case of the portable terminal A in FIG. 13, the process in step S1803 is a process of receiving a retransmission instruction from the portable terminal B and transmitting data to the portable terminal C. The process in step S1803 corresponds to the process executed by the mobile terminal A in FIG. 13C and the mobile terminal B in FIG.

  In step S1804, the CPU 201 of the mobile terminal transmits data instructed to be transmitted to the adjacent mobile terminal.

  In step S1805, the CPU 201 of the portable terminal determines whether or not the data transmission in step S1804 is successful.

  If the data transmission is successful (step S1805: YES), the processing shown in this flowchart is terminated.

  If the data transmission has failed (step S1805: NO), the process proceeds to step S1806.

  In step S1806, the CPU 201 of the mobile terminal determines whether or not the own device is a parent device terminal (whether or not it is a terminal located at the right end shown in FIGS. 12 to 14).

  If it is a parent terminal (step S1806: YES), the process proceeds to step S1807.

  If it is not the parent terminal (step S1806: NO), the process proceeds to step S1810.

  In step S1807, the CPU 201 of the mobile terminal transmits data to the two adjacent mobile terminals.

  In step S1808, the CPU 201 of the portable terminal determines whether the data transmission process in step S1807 has been successful.

  If successful (step S1808: YES), the processing shown in this flowchart is terminated.

  If it has failed (step S1808: NO), the process proceeds to step S1809.

  In step S1809, the CPU 201 of the portable terminal displays a message to re-execute data transmission by changing the arrangement on the display unit. The screen displayed here is the same as the screen shown in FIGS. 7, 9, and 11.

  For example, the portable terminal A in FIG. 12B executes the processing in step S1807 and ends the processing in this flowchart.

  In step S <b> 1810, the CPU 201 of the mobile terminal determines whether a mobile terminal is placed next to it.

  If it is arranged (step S1810: YES), the process proceeds to step S1811.

  If not arranged (step S1810: NO), the process proceeds to step S1813.

  In step S1811, the CPU 201 of the mobile terminal transmits data to the two adjacent mobile terminals.

  In step S1812, the CPU 201 of the portable terminal determines whether the data transmission process in step S1811 has been successful.

  If the data transmission process is successful (step S1812: YES), the process in this flowchart ends.

  If the data transmission process has failed (step S1812: NO), the process proceeds to step S1813.

  In step S <b> 1813, the CPU 201 of the mobile terminal makes a data retransmission request to the data transmission source. And the process of this flowchart is complete | finished.

  Note that the mobile terminal that has received the retransmission request in step S1813 executes the process of step S1803.

  For example, it is the mobile terminal B in FIG. 13B that determines YES in step S1812, and ends the processing of this flowchart.

  For example, it is the mobile terminal C in FIG. 14B that determines NO in step S1810, executes the processing in step S1813, and ends the processing in this flowchart.

  For example, it is mobile terminal B in FIG. 13C that determines NO in step S1812, executes the process in step S1813, and ends the process of this flowchart.
