Description

  The present invention relates to an order management system.

  In restaurants such as family restaurants and izakayas, order management systems that use electronic data to manage orders from customers are used. The controller of such an order management system has a function of receiving order data transmitted from a handy terminal or the like and transmitting data to each output device such as a printer or a display. The handy terminal inputs the order data after the employee is requested to order, and registers the order data in the controller by data transfer means such as wireless communication. The controller transmits data to each printer or the like based on the registered data, and outputs the slip data or displays it on the screen. The employee prepares the ordered food or drink according to the data and provides it to the customer. Employees always use the handy terminal when ordering from customers, so they always carry the handy terminal.

  The wireless communication data transmitted from the handy terminal is transmitted to the controller via an access point that is a wireless base unit in a general infrastructure mode. Multiple access points can be installed in a single system. In addition, since access points can communicate independently on different wireless channels, devices are installed on a plurality of wireless channels for fault tolerance of wireless communication. For example, an access point is installed by combining each of a 5 GHz band and a 2.4 GHz band.

  The registration of order data from the handy terminal uses a general technique of wireless LAN (Local Area Network) communication. For this reason, it often becomes an obstacle due to other wireless communication systems using the same frequency band. In particular, in the 2.4 GHz band, which has been used in advance in wireless LANs, communication failures often occur due to interference waves generated from microwave ovens and industrial products. In addition, since a recent wireless LAN is installed in a smartphone, the proportion of using a wireless LAN without using a public line has increased by arranging a wireless router equipped with a wireless LAN base unit in a restaurant or the like. As a result, wireless LAN interference often occurs.

  For this reason, interference is increasing in wireless LAN communications, and avoidance of interference has become essential. However, it was necessary to change the wireless LAN settings and which wireless channel should be used, or to change the access point settings using a personal computer etc. . Even if the access point is set to avoid interference, if the device fails and needs to be replaced, you want to inherit the previous access point settings, but the broken device settings. I didn't know, so the same failure could occur again.

  In an environment where a wireless failure or the like occurs, a wireless printer or a wireless repeater on the wireless slave side may reconnect to another access point because communication temporarily becomes impossible. As a result, the wireless printer cannot temporarily communicate, and communication with the reconnection destination may not be a good wireless environment, which may cause further wireless failure.

  When a wireless LAN failure occurs, order data cannot be transmitted from the handy terminal to the controller, and the delivery of received orders may be delayed without printing a slip from an output device such as a wireless printer. is there. For this reason, it is necessary to restore the failure of the wireless LAN as soon as possible.

  Due to the above problems, Patent Document 1 discloses that wireless devices (such as radio wave strength and the number of successful communication failures) are investigated with a device such as a handy terminal or a controller, and wireless settings are automatically updated by automatically updating settings related to wireless communication. A mechanism for automatically responding to failures is disclosed.

Japanese Patent No. 4825855

  However, the technique described in Patent Document 1 has a problem that settings relating to wireless communication of a single device can be automatically changed, but settings relating to wireless communication of the entire system cannot be collectively changed. In order to change the settings related to wireless communication of the entire system, it was necessary to make settings for each device.

  Therefore, the present invention has been made in view of the above-described circumstances, and an object thereof is to provide an order management system capable of collectively changing settings related to wireless communication of the entire order management system.

  The control unit 201 controls the entire handy terminal 20. In addition, when a communication failure occurs in the wireless communication unit 202, the control unit 201 changes the system ID indicating the wireless communication (wireless LAN) setting in the wireless communication unit 202. Then, the control unit 201 transmits the next system ID, which is the changed system ID, from the alternative communication unit 206 to the controller 30. Further, the control unit 201 transmits the next system ID to another device in the order management system 1 from the alternative communication unit 206 and sets it.

  The wireless communication unit 202 performs wireless communication using a wireless LAN based on the setting indicated by the system ID. The display unit 203 is a liquid crystal display (LCD, Liquid Crystal Display), an organic EL (Electro-Luminescence) display, or the like, and displays information. For example, the display unit 203 displays customer orders received by the input unit 204. The input unit 204 is a button, a touch panel, or the like, and accepts input. For example, the input unit 204 inputs a customer order. The storage unit 205 stores various information such as various settings and order data. Further, the storage unit 205 stores the system ID set in the own device. The alternative communication unit 206 communicates with an alternative communication means (for example, Bluetooth (registered trademark), IrDA (Infrared Data Association), or NFC (Near Field Radio Communication)) different from the wireless LAN.

  Next, the controller 30 will be described. FIG. 3 is a block diagram showing a configuration of the controller 30 in the present embodiment. As illustrated, the controller 30 includes a control unit 301 (setting unit, restart unit), a storage unit 302, a communication unit 303 (reception unit), a display unit 304, and an input unit 305.

  The control unit 301 controls the entire controller 30. In addition, the control unit 301 performs order processing. In addition, the control unit 301 transmits the next system ID received by the communication unit 303 to all devices in the order management system 1 and sets them. Then, the control unit 301 restarts all the devices in the order management system 1 and switches to the next system ID in which the system IDs of all the devices are set.

  The storage unit 302 stores various information such as order data received from the handy terminal 20, print data to be output to the printers 50 and 51, and setting information. Further, the storage unit 302 stores device connection information indicating a connection status with each device of the order management system 1 and a setting status of the next system ID. The communication unit 303 communicates with other devices via a wireless LAN, a wired LAN, or other communication means.

  The display unit 304 is a liquid crystal display, an organic EL display, or the like, and displays information. The input unit 305 is a keyboard, a mouse, or the like, and accepts input.

  Note that the configurations of the access point 40 and the repeater 41 are the same as those of the controller 30 with respect to the configuration mainly used in the present embodiment. However, the controller 30 has a storage unit 302 having a larger capacity than the access point 40 and the repeater 41.

  FIG. 4 is a schematic diagram illustrating a data structure and a data example of device connection information stored in the controller 30 according to the present embodiment. As illustrated, the device connection information includes items of a device name, an IP address, a connection destination 1, a connection destination 2, an update time, and a next system ID.

  The device name is a name of a device in the order management system 1. The IP address is the IP address of the corresponding device. The connection destination 1 is a device to which a corresponding device is directly connected. The connection destination 2 is a device to which the corresponding device is connected via the connection destination 1. The connection destination 1 “-” and the connection destination 2 “-” indicate that there is no connection destination. The update time is the date and time when the corresponding device next sets the system ID. The next system ID is the next system ID set for the corresponding device. The next system ID “-” indicates that the next system ID is not set.

  In the illustrated example, the IP address corresponding to the device name “AP01” is “10.0.0.1”, the connection destination 1 is “−”, the connection destination 2 is “−”, and the update time Is “2016/1/12 13:50”, and the next system ID is “1120123456”. The IP address corresponding to the device name “AP02” is “10.0.0.2”, the connection destination 1 is “−”, the connection destination 2 is “−”, and the update time is “2016/1”. / 12 13:50 ”, and the next system ID is“ 1120123456 ”. The IP address corresponding to the device name “AP03” is “10.0.0.3”, the connection destination 1 is “−”, the connection destination 2 is “−”, and the update time is “2016/1”. / 12 13:48 "and the next system ID is"-". The IP address corresponding to the device name “AP04” is “10.0.0.4”, the connection destination 1 is “AP02”, the connection destination 2 is “−”, and the update time is “2016/1”. / 12 13:30 "and the next system ID is"-". The IP address corresponding to the device name “PR01” is “10.0.0.31”, the connection destination 1 is “AP01”, the connection destination 2 is “−”, and the update time is “2016/1”. / 12 13:52 ”, and the next system ID is“ 1120123456 ”. The IP address corresponding to the device name “PR02” is “10.0.0.32”, the connection destination 1 is “−”, the connection destination 2 is “−”, and the update time is “2016/1”. / 12 13:50 ”, and the next system ID is“ 1120123456 ”. The IP address corresponding to the device name “HT01” is “10.0.0.128”, the connection destination 1 is “AP01”, the connection destination 2 is “−”, and the update time is “2016/1”. / 12 13:50 ”, and the next system ID is“ 1120123456 ”. The IP address corresponding to the device name “HT02” is “10.0.0.129”, the connection destination 1 is “AP02”, the connection destination 2 is “AP04”, and the update time is “2016/1”. / 12 13:47 "and the next system ID is"-".

  Next, in the order management system 1 according to the present embodiment, a wireless setting changing method for collectively changing settings related to wireless communication of the entire system will be described. 5 to 8 are diagrams for explaining a wireless setting changing method of the order management system 1 in the present embodiment.

  As shown in FIG. 5, the order management system 1 is assigned a system ID for grouping networks. Devices with different system IDs cannot communicate wirelessly. In the illustrated example, wireless communication is not possible between the group in which the system ID “123457” is set and the group in which the system ID “123456” is set. As a result, it is possible to prevent interference when a plurality of groups exist in the same wired LAN or when other groups of the wireless LAN exist in the vicinity. Each device of the order management system 1 is preset with a system ID of the group to which the device belongs.

  The system ID is an ID (identification information) uniquely indicating a setting related to the wireless LAN (wireless channel (frequency band) of the wireless LAN, ESSID (Extended Service Set Identifier), and wireless encryption key (password)). Each device in the order management system 1 generates a wireless LAN wireless channel, an ESSID, and a wireless encryption key based on the system ID. For example, each device generates a setting related to the wireless LAN from the system ID by combining one-configuration hash values, other characters, and the like.

  Thus, by setting the system ID to each device in the order management system 1, all devices in the order management system 1 can be connected by the same wireless LAN, and the controller 30 and each device communicate with each other. It becomes possible.

  Hereinafter, as illustrated in FIG. 6, a case where noise that interferes with the wireless communication relayed by the controller 30A occurs will be described. As illustrated, the handy terminal 20 </ b> A and the printer 50 cannot communicate with the controller 30. On the other hand, the handy terminal 20 </ b> B can communicate with the controller 30.

  As shown in FIG. 7, when the handy terminal 20A detects a communication error in the wireless LAN, the handy terminal 20A communicates with the controller 30A by an alternative communication unit different from the wireless LAN. Then, the handy terminal 20A transmits an HT abnormality detection request to the controller 30A. The HT abnormality detection request is data indicating that an abnormality has been detected in wireless LAN communication. This HT abnormality is not detected when communication cannot be performed because the communication distance is long and the radio wave intensity is weak, such as when roaming simply occurs. When the controller 30A receives the HT abnormality detection request from the handy terminal 20A, it returns the device connection information to the handy terminal 20A. The handy terminal 20A confirms information related to the update time among the device connection information received from the controller 30A, and whether there is a device whose time from the update time to the current time has exceeded a predetermined time (for example, 10 minutes). Search for no. If there is a device in which the time from the update time to the current time has exceeded a predetermined time, the device is determined to be a device that cannot perform wireless LAN communication. For example, in the example illustrated in FIG. 4, when the current time is “2016/1/12 13:52”, the update time of AP04 is “2016/1/12 13:30” and the update time to the current time. For a predetermined time (for example, 10 minutes) or more. In this case, the handy terminal 20A determines that the AP 04 is a device that cannot perform wireless LAN communication.

  When the handy terminal 20 </ b> A determines that there are other devices that are unable to communicate via the wireless LAN, the handy terminal 20 </ b> A determines the next system ID. The next system ID is obtained by changing the wireless channel from the currently used system ID. Then, the handy terminal 20A transmits the next system ID update to the controller 30A. The next system ID update includes the determined next system ID.

  When the controller 30A receives the next system ID update, the controller 30A stores the next system ID included in the received next system ID update. Note that the controller 30 retains channel information regarding the current wireless channel in which the failure has occurred as a history so that the wireless channel is not used in the future. Further, the controller 30 may prepare a list of usable wireless channels in advance so that, for example, the 2.4 GHz band is not used.

  Then, the controller 30A notifies the next system ID to all devices in the order management system 1 and sets them. For example, devices (handy terminal 20A, controller 30B, access point 40, printer 50, and printer 51) that communicate directly with controller 30A send notifications from the devices to controller 30A periodically (for example, every minute). Yes. Therefore, when receiving a notification from the device, the controller 30A adds the next system ID update notification to the response data for the notification and transmits it. The next system ID update notification includes the next system ID. Further, the controller 30A notifies other devices (the repeater 41 and the handy terminal 20B) that are not regularly communicating to perform polling. And controller 30A will add and transmit next system ID update notification to the response data with respect to the notification, if the notification from the apparatus which is not communicating regularly is received.

  When the controller 30A notifies all devices in the order management system 1 of the next system ID, the controller 30A transmits a restart instruction for instructing restart to all devices in the order management system 1. Note that the controller 30 may be restarted even if the next system ID is not set for all devices because there may be a failure of the device.

  As shown in FIG. 8, when the next system ID is notified from the controller 30, each device of the order management system 1 resets the system ID set in its own device to the next system ID. Each device holds the system ID “1010123456” of the own device and the individual ID “01” of the own device until the next system ID is notified. When the next system ID is notified from the controller 30, each device holds the notified next system ID “1120123456” in addition to the system ID of the own device and the individual ID of the own device. After that, when receiving a restart instruction from the controller 30, each device restarts, sets the next system ID “1120123456” as the system ID, and performs wireless communication based on the system ID.

  As a result, the system IDs of all the devices in the order management system 1 are updated all at once, and the wireless LAN connection is performed with the new system ID in all the devices after the restart.

  In the above-described example, the case where the system ID is automatically changed when the handy terminal 20 detects a failure in the wireless LAN has been described. However, even when the handy terminal 20 is manually updated to another system ID. Good. First, the user operates the handy terminal 20 to display an update screen for updating the system ID.

  FIG. 9 is an image diagram showing an example of an update screen displayed by the handy terminal 20 in the present embodiment. As shown in the figure, the update screen includes a “system ID update process” indicating that the system ID is updated, a current system ID “10101123456”, a next system ID “1120123456”, and an updated wireless ID. A channel “36ch”, an upper button B1, a lower button B2, a setting button B3, and a cancel button B4 are displayed. The upper button B1 and the lower button B2 are buttons for changing the radio channel. The setting button B3 is a button for setting the changed radio channel. The cancel button B4 is a button for canceling the update of the system ID.

  The user presses the upper button B1 or the lower button B2 to determine the radio channel. When the wireless channel is determined, the handy terminal 20 displays the system ID corresponding to the determined wireless channel as the next system ID on the update screen. Alternatively, when the next system ID is input on the update screen, the handy terminal 20 displays the corresponding wireless channel on the update screen. When the user determines the next system ID, the user presses the setting button B3. When the setting button B <b> 3 receives an input, the handy terminal 20 transmits a next system ID update including the determined next system ID to the controller 30.

  Thereafter, the handy terminal 20 receives device connection information from the controller 30. When the handy terminal 20 receives the device connection information, the handy terminal 20 displays a setting status screen.

  FIG. 10 is an image diagram showing an example of a setting status screen displayed by the handy terminal 20 in the present embodiment. As shown in the figure, the setting status screen includes “system ID update processing in progress” indicating that the system ID is being updated, the next system ID “1120123456”, and a setting status table indicating the setting status of each device. A restart button B11 and a cancel button B12 are displayed. The restart button B11 is a button for restarting the entire order management system 1. The cancel button B12 is a button for closing the setting status screen.

  The setting status table includes items of a device name, a setting process, and a connection destination. The device name is the name of each device. The setting process indicates whether the setting of the next system ID is completed or not completed. The connection destination is the connection destination 1. The handy terminal 20 generates a setting status table based on the device connection information received from the controller 30.

  In the example shown in FIG. 10A, the setting process for the device name “AP01” is “complete”, and the connection destination is “none”. The setting process for the device name “AP02” is “complete”, and the connection destination is “none”. The setting process for the device name “AP03” is “not yet”, and the connection destination is “none”. The setting process for the device name “AP04” is “not yet”, and the connection destination is “AP02”. The setting process for the device name “PR01” is “not yet”, and the connection destination is “AP01”. The setting process for the device name “PR02” is “complete”, and the connection destination is “none”. The setting process for the device name “HT01” is “complete”, and the connection destination is “AP01”. The setting process for the device name “HT02” is “not yet”, and the connection destination is “AP04”.

  The handy terminal 20 acquires device connection information from the controller 30 periodically (for example, every 10 seconds) and updates the connection status screen. In the example shown in FIG. 10A, the setting process of the device name “PR01” indicating the printer 50 is “not yet”. Thereafter, when the next system ID is notified from the controller 30A to the printer 50 and the next system ID is set in the printer 50, the setting process corresponding to the device name “PR01” is “completed” as shown in FIG. ”. Other data examples shown in FIG. 10B are the same as those in FIG.

  In this way, the handy terminal 20 displays the setting status of each device on the setting status screen, so that the user can grasp the setting status of each device in the order management system 1.

  When the user confirms that the setting processing of all connectable devices in the order management system 1 has been completed, the user presses the restart button B11. When the restart button B11 accepts an input, the handy terminal 20A transmits a restart request requesting the controller 30A to restart. When the controller 30A receives the restart request from the handy terminal 20A, the controller 30A transmits a restart instruction to all the devices in the order management system 1 to restart all the devices in the order management system 1, and the order management system The system ID of the wireless LAN used by 1 is updated to the next system ID.

  However, since wireless LAN communication cannot be performed in the first place, it can be assumed that a device using the wireless LAN cannot communicate and cannot set the next system ID. For example, if PR01, which is the printer 50, cannot connect to the wireless LAN and is searching for the connection destination of the wireless LAN, the next system ID is not set for the printer 50. In this case, the user can know from the setting status screen displayed on the handy terminal 20 that the next system ID is not set in the printer 50. Therefore, the user may bring the handy terminal 20 close to the printer 50 and set the next system ID to the printer 50 directly from the handy terminal 20. The handy terminal 20 determines that the next system ID is not set for the printer 50 based on the device connection information received from the controller 30. Then, the handy terminal 20 communicates with the printer 50 by the alternative communication means and notifies the printer 50 of the next system ID. When the next system ID is notified, the printer 50 sets the notified next system ID in its own apparatus. Thus, it is assumed that the printer 50 in which the next system ID is set directly from the handy terminal 20 cannot receive a restart instruction from the controller 30. For this reason, when the next system ID is directly notified from the handy terminal 20, the printer 50 immediately restarts and updates the system ID to the next system ID.

  Thereafter, the handy terminal 20 notifies the controller 30 that the next system ID has been set for the printer 50. The controller 30 updates the device connection information based on the information notified from the handy terminal 20. Further, the handy terminal 20 sets the setting process of the device name “PR01” on the setting status screen to “complete”. At this time, the handy terminal 20 displays so that it can be seen that the next system ID has been set directly from the handy terminal 20 to the printer 50, for example, by shading the column of the device name “PR01”.

  In addition, after all devices are restarted, the controller 30 sets the next system ID (the next system ID setting is completed in all devices, or there is a device for which the next system ID is not set). To the handy terminal 20. The handy terminal 20 displays the setting status of the next system ID received from the controller 30 and notifies the user. Alternatively, the controller 30 may cause the printers 50 and 51 to print the next system ID setting status and notify the user. The user can know the setting status of the next system ID based on the display on the handy terminal 20 or the slips output from the printers 50 and 51. At this time, when there is a device for which the next system ID is not set, the user may directly set the next system ID for the corresponding device using the handy terminal 20. As a result, it is possible to set a system ID for the corresponding device next time so that all devices can be connected to the wireless LAN.

  FIG. 11 is a flowchart showing a processing procedure of communication processing executed by the handy terminal 20 in the present embodiment. The processing shown in this figure is executed when the handy terminal 20 performs communication by wireless LAN.

(Step S <b> 101) The control unit 201 executes wireless LAN communication processing in the wireless communication unit 202. Thereafter, the process proceeds to step S102.
(Step S102) The control unit 201 determines whether the wireless LAN communication process has succeeded or failed in step S101. If the control unit 201 determines that the process has succeeded, the process ends. If the control unit 201 determines that the process has failed, the process proceeds to step S103.

(Step S <b> 103) The control unit 201 switches the wireless LAN relay in the wireless communication unit 202 to another relay device or connects to the controller 30 by an alternative communication unit in the alternative communication unit 206. Then, the control unit 201 transmits an HT abnormality detection request to the controller 30. Thereafter, the process proceeds to step S104.
(Step S <b> 104) The control unit 201 receives device connection information from the controller 30, and determines whether a wireless LAN communication abnormality has been detected based on the received device connection information. If the control unit 201 determines that a communication abnormality has been detected, the process proceeds to step S105. If the control unit 201 determines that no communication abnormality has been detected, the process ends.

(Step S105) The control unit 201 displays an update screen on the display unit 203 and selects the next system ID (change contents). Thereafter, the process proceeds to step S106.
(Step S106) The control unit 201 determines whether the setting button B3 has received input (OK) or the cancel button B4 has received input (cancel) on the update screen. If the control unit 201 determines that it is OK, the process proceeds to step S107. Further, when the control unit 201 determines that it is cancelled, the process ends.

(Step S107) The control unit 201 transmits a system ID update including the system ID set on the update screen to the controller 30 to register and reflect the next system ID. Thereafter, the process proceeds to step S108.
(Step S <b> 108) The control unit 201 displays a setting status screen (setting completion information) on the display unit 203. Thereafter, the process proceeds to step S109.
(Step S109) The control unit 201 determines whether or not the cancel button B12 has received an input on the setting status screen. If the control unit 201 determines that the cancel button B12 has received an input, the process ends. If the control unit 201 determines that the cancel button B12 has not received an input, the process proceeds to step S110.

  (Step S110) The control unit 201 determines whether or not the restart button B11 has received an input on the setting status screen. If the control unit 201 determines that the restart button B11 has received an input, the process proceeds to step S114. If the control unit 201 determines that the restart button B11 has not received an input, the process proceeds to step S111.

(Step S <b> 111) The control unit 201 uses the alternative communication unit in the alternative communication unit 206 to search whether there is a device whose setting process is “unknown” in the vicinity. Thereafter, the process proceeds to step S112.
(Step S112) The control unit 201 determines whether or not the corresponding device is detected in step S111. If the control unit 201 determines that the corresponding device has been detected, the process proceeds to step S113. If the control unit 201 determines that the corresponding device has not been detected, the process returns to step S108.

  (Step S <b> 113) The control unit 201 sets the next system ID for the corresponding device by the alternative communication unit in the alternative communication unit 206. Then, the control unit 201 notifies the controller 30 that the next system ID has been set for the device. Thereafter, the process returns to step S108.

  (Step S <b> 114) The control unit 201 transmits a restart request to the controller 30 to restart all devices in the order management system 1. Thereafter, the process is terminated and the device itself is restarted.

  FIG. 12 is a flowchart showing a processing procedure of communication processing executed by the controller 30 in the present embodiment. The process shown in this figure is executed when the controller 30 receives data from another device.

(Step S <b> 201) The control unit 301 executes reception event processing in which the communication unit 303 receives data from another device. Thereafter, the process proceeds to step S202.
(Step S202) The control unit 301 determines whether the received data received in step S201 is an HT abnormality detection request, a next system ID update, or a notification from a device. If the control unit 301 determines that the request is when an HT abnormality is detected, the process proceeds to step S203. If the control unit 301 determines that the system ID is updated next time, the process proceeds to step S204. If the control unit 301 determines that the notification is from the device, the process proceeds to step S207.

  (Step S <b> 203) The control unit 301 returns device connection information to the handy terminal 20 that is the transmission source of the HT abnormality detection request via the communication unit 303. Thereafter, the process returns to step S201.

(Step S <b> 204) The control unit 301 stores the received next system ID in the storage unit 302. Thereafter, the process proceeds to step S205.
(Step S205) The control unit 301 responds to the handy terminal 20 that is the transmission source of the system ID update via the communication unit 303 with the completion of data update indicating that the system ID has been updated next time. Thereafter, the process proceeds to step S206.
(Step S <b> 206) The control unit 301 polls to acquire information on the next system ID in order to notify a device that is not regularly communicating via the communication unit 303 that the next system ID has been updated. Notify the corresponding device to do so. Thereafter, the process returns to step S201.

(Step S207) The control unit 301 confirms the received data. The received data includes information indicating whether or not the next system ID has already been set. Thereafter, the process proceeds to step S208.
(Step S208) The control unit 301 updates device connection information based on the received data. For example, when the next system ID has already been set, the control unit 301 writes the set next system ID and its update time in the device connection information. Thereafter, the process proceeds to step S209.

(Step S209) The control unit 301 confirms the setting (update) of the next system ID. Thereafter, the process proceeds to step S210.
(Step S210) The control unit 301 determines whether or not the next system ID is set (updated). If the control unit 301 determines that it has been updated, the process proceeds to step S211. If the control unit 301 determines that the information has not been updated, the process proceeds to step S212.

(Step S211) The control unit 301 adds the next system ID update notification to the response data. Thereafter, the process proceeds to step S212.
(Step S <b> 212) The control unit 301 returns response data to the device that is the transmission source of the reception data via the communication unit 303. Thereafter, the process returns to step S201.

  As described above, in this embodiment, the handy terminal 20 stores the system ID indicating the wireless communication setting, the storage unit 205 that stores the system ID, the wireless communication unit 202 that performs wireless communication based on the setting indicated by the system ID, and the system ID. And a control unit 201 that transmits the next system ID that is the changed system ID to the controller 30. In addition, the controller 30 transmits the communication unit 303 that receives the next system ID from the handy terminal 20 and the received next system ID to all the devices in the order management system 1 and sets them. And a control unit 301 that restarts all devices and switches to the next system ID in which the system IDs of all the devices are set. As a result, the order management system 1 does not need to set the wireless channel set in the access point again for each individual device even when a wireless LAN failure or the like occurs. Therefore, it is possible to collectively change the wireless LAN settings set for all the devices by one operation from the handy terminal 20. That is, it is possible to collectively change the settings relating to wireless communication of the entire order management system 1.

  In addition, since the controller 30 manages the system ID, it is not necessary to manually reflect the wireless LAN setting again when replacing each device. Therefore, the wireless LAN setting procedure can be minimized.

  The control unit 201 of the handy terminal 20 changes the system ID when a communication failure occurs in the wireless communication unit 202. Accordingly, when a communication failure occurs in the wireless communication in the order management system 1, the wireless communication setting can be automatically changed.

  Further, the control unit 201 of the handy terminal 20 transmits the next system ID to the controller 30 from the alternative communication unit 206 that communicates with the wireless communication unit 202 using a different communication means. As a result, the handy terminal 20 can transmit the next system ID to the controller 30 even when a failure occurs in the wireless LAN and the wireless communication unit 202 cannot perform wireless communication.

  Further, the control unit 201 of the handy terminal 20 transmits and sets the next system ID from the alternative communication unit 206 to other devices in the order management system 1. Thereby, even when a failure occurs in the wireless LAN and the other device cannot communicate wirelessly, the next system ID can be set in the other device.

  Note that all or some of the functions of each unit included in the handy terminal 20 or the controller 30 in the embodiment described above are recorded on a computer-readable recording medium and a program for realizing these functions is recorded on the recording medium. It may be realized by reading the recorded program into a computer system and executing it. Here, the “computer system” includes an OS and hardware such as peripheral devices.

  The “computer-readable recording medium” refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, and a CD-ROM, and a storage unit such as a hard disk built in the computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program that holds a program for a certain period of time. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the system ID is used as the group ID. However, the present invention is not limited to this, and a part of the system ID may be used as the group ID. In this case, a part of the system ID is used as the ESSID. For example, in the previous example, the system ID is “1010123456”, and the ESSID and the encryption key are calculated from these values. However, when the fourth digit to the ninth digit are used as the original data for calculating the ESSID and the encryption key, it is possible to set a radio channel separately in addition to a mechanism for preventing radio interference properly.

  In such a mechanism, after the device connected to the wired LAN can update the “next system ID” and the wireless LAN channel is automatically changed, the new wireless LAN channel is used. Can work.

  In this case, there may be a case where the client side device cannot be connected due to a wireless failure, etc., but if a wired LAN device already operates with a new wireless channel, the wireless channel is not affected by noise or the like. Can be operated. As a result, if the client side is trying to establish a wireless connection with the default wireless channel and cannot establish a successful connection, another channel is searched, but a wireless connection can be automatically established. After that, after connecting with the new wireless channel, the client-side device acquires from the controller 30 that the system ID has already been changed, and updates the setting of the own device again.

  In this way, even after the next restart, a new system ID is set, so that it is possible to detect the wireless channel from the beginning and save the time to detect the wireless master unit and to connect at high speed. Become.
