An example of an embodiment of the present disclosure will be described below with reference to the drawings. In addition, the same reference numerals are given to the same or equivalent components and parts in each drawing. Furthermore, the dimensional ratios in the drawings are exaggerated for convenience of explanation and may differ from the actual ratios.

FIG. 1 is a diagram showing an example of the configuration of an order management system 1 according to an embodiment of the present invention.

As shown in FIG. 1, an order management system 1 according to the present embodiment is a system constructed in a store (not shown) such as a family restaurant or a pub. The order management system 1 includes a controller 10, communication devices 20, 30, and 31, an accounting device 50, and a relay device 60.

Further, the controller 10 is capable of communicating with a communication device 31 via a wireless network N3. Note that the wired network N2 may be, for example, a LAN (Local Area Network) built in a store using wires. Wi-Fi (registered trademark), which is an example of a wireless LAN standard, is applied to the wireless network N3. The controller 10 also has a wireless communication function as an access point for the wireless network N1.

The communication devices 20, 30, and 31 according to the present embodiment communicate with each of a business terminal 40 such as a handy terminal used by a customer service person for work and a personal terminal 42 such as a smartphone owned by the customer service person via a wireless network N1. It is said that communication is possible. Note that the business terminal 40 and the personal terminal 42 are examples of terminals. Moreover, as an example, a LAN or the like built wirelessly within a store is applied to the wireless network N1. More specifically, Wi-Fi (registered trademark), which is an example of a wireless LAN standard, is applied as the wireless network N1.

Next, the operation of the controller 10 will be explained.

FIG. 6 is a flowchart showing the flow of setting update processing by the controller 10. Setting update processing is performed by the CPU 11 reading a setting update program from the ROM 12 or storage 14, expanding it to the RAM 13, and executing it.

When periodically updating the communication settings, the CPU 11 executes settings for periodic updates (step S101). A timer event occurs depending on the periodic update settings. Any day or day of the week, such as the first day of every month, every Monday, or the second Friday of every month, can be specified as the timer event.

Following step S101, the CPU 101 determines whether there is a setting for regular update (step S102). As a result of the determination in step S102, if there is a setting for regular update (step S102; Yes), the CPU 101 executes setting of a timer event (step S103). As a result of the determination in step S102, if there is no periodic update setting (step S102; No), the CPU 101 skips the process in step S103.

Subsequently, the CPU 101 waits for a communication setting update event to occur (step S104).

When a communication setting update event occurs, the CPU 101 determines that the update event is an event (device event) or a timer event (step S105).

As a result of the determination in step S105, if the generated update event is a device event, the CPU 101 causes an update event from the device to occur (step S106). Following step S106, the CPU 101 sets Wi-Fi information consisting of a set of SSID and passphrase as settings for the wireless network N1 (step S107).

As a result of the determination in step S105, if the generated update event is a timer event, the CPU 101 generates an update event by the timer (step S108). Following step S108, the CPU 101 determines whether or not the permission device set to permit updating of Wi-Fi information is set to make an inquiry before updating the Wi-Fi information (step S109). ). The permission device set to permit updating of Wi-Fi information is, for example, a business terminal 40 owned by the store manager of the store where the order management system 1 is installed.

As a result of the determination in step S109, if it is not set to carry out an inquiry (step S109; No), the CPU 101 executes the setting of Wi-Fi information in step S107. On the other hand, if the result of the determination in step S109 is that the inquiry is set (step S109; Yes), the CPU 101 subsequently inquires of the permission device whether to update the Wi-Fi information (step S110). .

Following step S110, the CPU 101 determines whether the inquiry result is a Wi-Fi information update request or a cancellation of the process (step S111).

As a result of the determination in step S111, if the result of the inquiry is a Wi-Fi information update request, the CPU 101 executes the Wi-Fi information setting in step S107. On the other hand, as a result of the determination in step S111, if the result of the inquiry is to cancel the process, the CPU 101 returns to step S102 to determine whether periodic update is set.

After executing the Wi-Fi information setting in step S107, the CPU 101 notifies the set Wi-Fi information to the communication devices 20, 30, and 31 (step S112).

FIG. 7 is a diagram showing how Wi-Fi information is notified from the controller 10 to the communication devices 20, 30, and 31. Wi-Fi information is notified from the controller 10 to the communication devices 20, 30, and 31 via the wired network N2 or the wireless network N3.

The communication devices 20 and 30 connected to the wired network N2 communicate with the controller 10 to obtain Wi-Fi information at startup and when updating Wi-Fi information. The communication device 31 connected to the wireless network N3 is connected to the wireless network N3 using Wi-Fi information different from that of the business terminal 40 and the personal terminal 42. That is, the communication device 31 has multiple wireless interfaces. Therefore, the communication device 31 can acquire Wi-Fi information for the business terminal 40 and the personal terminal 42 through the wireless network N3.

Following step S112, the CPU 101 updates the Wi-Fi information of its own device with the Wi-Fi information set in step S107. Furthermore, the communication devices 20, 30, and 31 also automatically update the Wi-Fi information based on the acquired Wi-Fi information (step S113).

After updating the Wi-Fi information of the own device and the communication devices 20, 30, and 31 in step S113, the process returns to step S102 to determine whether periodic update is set.

When the business terminal 40 and the personal terminal 42 are always connected to devices in the store by wireless communication, the business terminal 40 and the personal terminal 42 acquire updated Wi-Fi information in the same way as the communication device 31. It is possible. However, when Wi-Fi information is automatically updated, there is a possibility that the update will be performed automatically on terminals that do not need to be updated, such as a personal terminal 42 owned by an employee who has already left the store.

Therefore, it is desirable that the business terminal 40 and the personal terminal 42 update the Wi-Fi information manually rather than automatically. When manually updating the Wi-Fi information settings, users of the business terminal 40 and personal terminal 42 need to add the SSID and passphrase to the business terminal 40 and personal terminal 42 in order to connect to the wireless network N1. In order to easily input the SSID and passphrase, the communication devices 30 and 31 output a two-dimensional code containing Wi-Fi information consisting of the SSID and passphrase. The two-dimensional code may be output by the user operating the communication devices 30 and 31, or by an instruction from the controller 10. The business terminal 40 and the personal terminal 42 set Wi-Fi information by reading the two-dimensional code with an imaging device.

Show specific use cases. FIG. 8 is a diagram showing a partial configuration of the order management system 1 according to the embodiment of the present invention. FIG. 8 shows a state after the Wi-Fi information of the communication device 30 has been updated with the Wi-Fi information generated by the controller 10. Here, when the personal terminal 42 attempts to connect to the wireless network N1a using the Wi-Fi information before the update, since the Wi-Fi information of the communication device 30 has been updated, the personal terminal 42 connects to the wireless network N1a using the Wi-Fi information before the update. Unable to connect to.

Therefore, the user operates the communication device 30 or instructs the controller 10 to output a two-dimensional code containing Wi-Fi information consisting of an SSID and a passphrase. FIG. 9 is a diagram showing a partial configuration of the order management system 1 according to the embodiment of the present invention. FIG. 9 shows a state in which a paper 70 on which a two-dimensional code 71 is printed is being output from the communication device 30. The personal terminal 42 can set updated Wi-Fi information by reading the two-dimensional code 71 with an imaging device (not shown).

FIG. 10 is a diagram showing a partial configuration of the order management system 1 according to the embodiment of the present invention. FIG. 10 shows a state after the Wi-Fi information of the communication device 30 has been updated with the Wi-Fi information generated by the controller 10. When the personal terminal 42 attempts to connect to the wireless network N1b using the updated Wi-Fi information, the personal terminal 42 becomes able to connect to the communication device 30.

The business terminal 40 and the personal terminal 42 are often damaged and replaced because employees carry them around all the time to register orders. Therefore, when registering Wi-Fi information for the replaced business terminal 40 and personal terminal 42, settings can be made using two-dimensional codes output from the communication devices 30 and 31. Therefore, maintenance work on the business terminal 40 and personal terminal 42 in the store becomes extremely easy, and the cost of introducing a wireless LAN system can be reduced.

Note that output of a two-dimensional code containing Wi-Fi information by the communication devices 30 and 31, or display of the setting value of the Wi-Fi information itself, may be allowed only to be performed by an employee who has permission in advance. For example, by inputting a password known only to an authorized employee such as a store manager into the communication devices 30, 31, it may be possible to output a two-dimensional code or display the set value itself. Alternatively, for example, only an authorized employee such as a store manager may be able to send an instruction to output a two-dimensional code to the communication devices 30 and 31 from the business terminal 40 carried.

Furthermore, a two-dimensional code containing Wi-Fi information may be presented on the screen of a business terminal 40 carried only by an authorized employee such as a store manager. By having the two-dimensional code presented on the screen of the business terminal 40 carried only by authorized employees, leakage of Wi-Fi information can be suppressed.

Further, the event for updating the Wi-Fi information may be generated only by operation of the business terminal 40 or the like by an authorized person such as a store manager.

In addition, various processors other than the CPU may execute the setting update process that the CPU reads and executes the software (program) in each of the above embodiments. In this case, the processor includes a PLD (Programmable Logic Device) whose circuit configuration can be changed after manufacturing, such as an FPGA (Field-Programmable Gate Array), and an ASIC (Application Specific Integrated Circuit). In order to execute specific processing such as An example is a dedicated electric circuit that is a processor having a specially designed circuit configuration. Further, the setting update process may be executed by one of these various processors, or by a combination of two or more processors of the same type or different types (for example, a combination of multiple FPGAs, and a combination of a CPU and an FPGA). etc.). Further, the hardware structure of these various processors is, more specifically, an electric circuit that is a combination of circuit elements such as semiconductor elements.

Further, in each of the embodiments described above, a mode has been described in which a program for setting update processing is stored (installed) in the ROM or storage in advance, but the present invention is not limited to this. The program is recorded on recording media such as CD-ROM (Compact Disk Read Only Memory), DVD-ROM (Digital Versatile Disk Read Only Memory), and USB (Universal Serial Bus) memory. It may also be provided in a different format. Further, the program may be downloaded from an external device via a network.
